-# DELEGATION SPECIFICATION: HARNESS-DRIVEN VALIDATION LOOP
-slug: sketch-focus-arbiter · repo: /home/tommaso/projects/apps/orca_cad · branch: cad-mainline
-
-## 1. TARGET GOAL
-
-**Functional Objective.** Keyboard input in the Design tab is routed by WHAT THE KEY IS, not by
-which widget the window manager decided to focus. Adopted from FreeCAD's
-`DrawSketchKeyboardManager::detectKeyboardEventHandlingMode`
-(src/Mod/Sketcher/Gui/DrawSketchKeyboardManager.cpp), which never queries focus at all:
-
-  - digit, `-`, `.`, `,`  -> the open value field
-  - Backspace / Delete    -> the open value field (when one is open)
-  - Enter / Return / Tab  -> commit the field, control returns to the view
-  - a letter              -> the sketch-tool shortcut map, as today
-  - Esc                   -> the existing CadLevel LIFO (DesignInteraction.hpp), unchanged
-  - anything else         -> sticky: whoever had it keeps it
-
-Observable postcondition: for EVERY sketch tool that opens a value field, a value typed
-immediately after the field appears — with NO click into the field — is the value committed.
-Today the prefill is committed instead whenever the WM withholds focus.
-
-**Target Files / Scope (writable).**
-  src/slic3r/GUI/CAD/DesignPanel.cpp        (the arbiter lives in the existing wxEVT_CHAR_HOOK)
-  src/slic3r/GUI/CAD/DesignCanvas.cpp/.hpp  (forwarding entry points only)
-  src/slic3r/GUI/CAD/SketchInlineEditor.cpp/.hpp (accept a programmatically delivered character)
-  scripts/CAD/check-gui-click-edit.py       (F2P oracle — authoring exception, see §4)
-Everything else read-only. No dependency additions, no reformatting.
-
-**Open Bindings.**
-  - The in-canvas ImGui field on wip/in-canvas-value-field is NOT in scope. Default: the arbiter
-    is implemented against the CURRENT wxFrame field on cad-mainline, because content-based
-    routing makes the window's focus irrelevant either way. If it later moves in-canvas the
-    arbiter is unchanged.
-  - Tools whose field is opened by a toolbar button rather than a gesture (Constrain path) are
-    covered by the same arbiter but are not in the F2P tool list. Default: assert them in P2P only.
-
-## 2. HARNESS ENVIRONMENT & GROUND TRUTH
-
-The rig container `orcacad-gui` on nativedev IS the harness. Xvfb `:11` + openbox, the app under
-test, `xdotool` for synthetic input, and an MCP socket at `/tmp/mcp.sock` that reports sketch
-state as JSON. It is a closed loop: drive input, read geometry back, assert. No window manager
-politics, no human.
-
-  Harness interface (ordered; each slot one invocation, one exit code):
-    S1 sync    docker cp <file> orcacad-gui:/OrcaSlicer/<path>
-    S2 build   docker exec orcacad-gui ninja -C /OrcaSlicer/build orca-slicer
-    S3 restart docker exec orcacad-gui /OrcaSlicer/scripts/CAD/start-headless-gui.sh
-    S4 F2P     docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-click-edit.py --attach
-    S5 P2P     docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-sketching.py
-
-**F2P.** `scripts/CAD/check-gui-click-edit.py`. For each of Line, Rectangle, Circle, Slot,
-Polygon, Ellipse and Rounded rectangle: arm the tool, draw it, and type a value that differs
-from the prefill WITHOUT clicking the field. Assert the committed value equals the typed value.
-The ladder must FAIL against unmodified cad-mainline — that is what proves it asserts something.
-
-**P2P.** `scripts/CAD/check-gui-sketching.py`, the existing gesture ladder, minus anything red at
-baseline. NOTE: it calls `focus_field()` — one click into the field before typing — which is the
-workaround this whole task removes. It stays green as a regression guard; it is NOT evidence.
-
-**Test Integrity Constraint.** `focus_field()` in check-gui-sketching.py must NOT be deleted to
-make things pass, and check-gui-click-edit.py must NOT be weakened. Either invalidates the run.
-
-## 3. VERIFICATION COMMANDS
-1. Static: `docker exec orcacad-gui ninja -C /OrcaSlicer/build orca-slicer` (warnings delta only;
-   this repo configures no linter — the compiler is the static gate. Absolute-zero is NOT the gate.)
-2. Harness: `docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-click-edit.py --attach`
-3. Regression: `docker exec -e DISPLAY=:11 orcacad-gui python3 /tmp/check-gui-sketching.py`
-
-## 4. CONVERGENCE LOOP — ceiling 8 iterations
-EDIT (scoped) -> EXECUTE S1..S5 -> PARSE the ladder's per-tool assertions and the [UX]/[KEYTRACE]
-lines -> PATCH from the parsed cause. On ceiling without convergence: stop, report the last diff
-and the unresolved failure set. Do not report success.
-
-F2P authoring exception: check-gui-click-edit.py is writable, and must be shown RED against
-unmodified source before any source edit counts.
-
-## 5. TERMINATION CRITERIA
-- [ ] S2 exits 0, and introduces no compiler warning absent from the baseline.
-- [ ] S4 ALL_PASSED — every tool commits the typed value, no click into the field.
-- [ ] S5 shows zero regressions against its recorded baseline pass count.
-- [ ] F2P proven red without the fix (source stashed, ladder re-run, must FAIL).
-
-## 6. GUARDRAILS
-Zero-assumption: no completion claim without captured stdout and exit codes. Oracle supremacy:
-the ladder's verdict overrides my judgement. Blast radius: §1 files only. Baseline obligation:
-run §3 once before the first edit and record it.

-# OrcaSlicer system profiles
-
-This skill describes how OrcaSlicer system profiles are drafted and shaped: the rules, equations and
-patterns a profile follows. Use it to draft new profiles, modify existing ones, fix profile issues and
-review profile changes.
-
-A bundle is the index `resources/profiles/<Vendor>.json` plus the folder `<Vendor>/`. The vendor id is
-the filename stem (`BBL`), not the index's display `name` (`Bambulab`). The index is the loader's only
-entry point: an unindexed preset never loads. `OrcaFilamentLibrary` is the shared filament bundle,
-loaded first; `blacklist.json` is data, not a bundle.
-
-## References

-Read the reference for the task before editing; load others only when the task crosses into them.
-Paths below are relative to this skill. Commands run from the repository root; on Windows use `py -3`
-for `python3`.

-
-## Rules
-
-1. **Bump the `version` of every bundle you change**, `OrcaFilamentLibrary.json` included when affected.
-   Increment the last component and carry `.99` into the third (`02.04.00.99` → `02.04.01.00`). The
-   updater installs only a strictly newer version, and CI does not check the bump.
-2. **Register every preset, bases included, parents before children.** `update-index` writes the four
-   `*_list` arrays from the files on disk; `check` fails unless the index equals its output. Each index
-   entry's `name` must equal the file's `name`.
-3. **Generate ids; never invent or copy them.** Keep existing ids during ordinary tuning. New presets
-   normally omit them until `generate-id`; bases carry no `setting_id`. BBL's own `setting_id`s and a wrongly
-   inherited `filament_id` need the explicit handling in [ids.md](references/ids.md).
-4. **A name is an identity; preserve shipped selectable names.** Every reference (`inherits`,
-   `compatible_printers`, `default_*`, `printer_model`) is the exact, case-sensitive `name`. Renaming or
-   deleting a shipped selectable preset, or flipping its `instantiation` from `"true"` to `"false"`,
-   needs `renamed_from` (a `;`-separated string) on a selectable successor
-   ([migration rules](references/vendor-bundle.md#renamed_from)); update in-tree references too.
-5. **Values are strings or arrays of strings.** `"instantiation": "false"`, never `false`. A
-   `machine_model`'s `nozzle_diameter` is a `;`-separated string; a `machine`'s is an array. Custom
-   G-code is one string. Wrong types can abort loading of the bundle or of every vendor
-   ([failure scopes](references/vendor-bundle.md#failure-scopes)).
-6. **Unknown keys are dropped silently.** Confirm every new key exists in
-   `src/libslic3r/PrintConfig.cpp`; a key a neighbouring file writes is no evidence it exists. `check` rejects,
-   and `normalize` removes, known obsolete keys, but neither detects an arbitrary misspelling. A key
-   missing from the definitions may be a legacy name the loader still renames
-   (`tool_change_gcode` → `change_filament_gcode`) or whose value it rewrites (`DirectDrive` →
-   `Direct Drive`); check `PrintConfigDef::handle_legacy` before removing one, and write the current name
-   in new edits.
-7. **Write overrides only.** Inherit the bundle's bases and restate just what differs; follow the
-   bundle's existing layering and style, except that a new filament prefers the library's bases. A
-   value that every preset of a group shares goes on the group's base
-   ([shared bases](references/shared-bases.md)).
-8. **One load error can discard a whole vendor bundle**: an unresolved `inherits`, a missing indexed
-   file, two selectable presets with one name, an unknown `printer_model` or `printer_variant`, a
-   filament with no resolvable `filament_id`, `nil` in a non-nullable key. `inherits` and `include`
-   resolve only inside the bundle, except that filaments may inherit from OrcaFilamentLibrary.
-9. **Filament compatibility names exact printer variants.** Every instantiated filament outside the
-   library writes a non-empty `compatible_printers` in its own file. Library fallbacks may omit it;
-   library printer-specific tunes use a non-empty list. One variant may be claimed by only one preset
-   per filament product (`filament_id`); an overlap is resolved by moving the variant to the most
-   specific preset, which is preferred over deleting a preset
-   ([one variant, one profile](references/filament-profiles.md#overlapping-coverage-one-variant-one-profile-per-product)).
-10. **One all-printer preset per product; colour is a runtime property, never a preset.** Never ship
-    presets that differ only by colour. CI accepts them, so this is a review call
-    ([colour](references/filament-profiles.md#colour-is-a-runtime-property)).
-11. **Write a variant key at full width or not at all.** A key in the four variant sets holds exactly
-    `N` values in the selectable preset that writes it, `N = S × k` in the
-    [sizing equation](references/extruder-variants.md#sizing-equation): one per variant, a (normal,
-    silent) pair per variant for the `machine_max_*` limits; one value is not "the same for every
-    variant". Profiles must be correct as written: `check` judges each selectable preset by the
-    equation, never by what the loader pads or cuts, and `check --strict` also holds what a preset
-    inherits to its own width, as BBL writes it. A base is never judged on its own: its array widths
-    count, under `--strict`, where they reach a preset, while the id and layout rules judge the
-    composed preset, inherited values included, without it. Declare the variant layout on a
-    multi-extruder printer whose extruders need different values
-    ([widths](references/extruder-variants.md#widths)).
-12. **Run the full checks before reporting completion.** A `--vendor` run is only a development loop.
-    Review also covers version bumps, assets, non-default processes and hardware tuning, which CI cannot
-    establish.
-
-## Names
-
-| Type | Shape | What the loader uses |
-| --- | --- | --- |
-| `machine_model` | `<Model>` (`Bambu Lab X1 Carbon`) | the exact string, named by each variant's `printer_model`; also the `<Model>_cover.png` stem |
-| `machine` | `<Model> <nozzle> nozzle` | the exact string, named by `compatible_printers`; `printer_variant` holds the nozzle token (`0.4`, [rules](references/machine-profiles.md#printer_model-and-printer_variant)) |
-| `process` | `<lh>mm <Quality> @<target>` | the exact string when referenced or selected; `@<target>` is a label, compatibility comes from the preset's list or condition |
-| `filament` | `<Product> @<target>` | text before the first `@` is the alias (shadowing, `filament_id`); the rest is a label, with reserved targets `@base` and `@System` |
-
-The shapes are convention; `check` enforces only uniqueness. Per-type conventions, base names and
-filename rules are in [naming.md](references/naming.md).
-
-## Creating or modifying a profile
-
-1. **Inspect the diff and the neighbouring presets.** Read their `name`, parent chain and children:
-   edits to a base, or to a leaf that others inherit, propagate. Match the bundle's structure and write
-   only overrides. New files use tab indentation, LF and a trailing newline; preserve unrelated
-   formatting in existing files. Match filename case exactly and use
-   [cross-platform names](references/naming.md#filenames-and-paths).
-2. **Author explicit metadata.** Set `type` yourself (`machine` vs `machine_model` especially), and use
-   `"from": "system"` and a string `instantiation` on config presets. Omit ids on new presets unless
-   [ids.md](references/ids.md) requires special handling; retain them on existing ones. Complete
-   compatibility, defaults, assets and any rename migration using the task reference.
-3. **Put shared values on shared bases** when drafting several presets, and after `fix-variant`, which
-   widens an array in every preset that writes it and moves nothing. Each value goes on the base of the
-   level that determines it, a new base only where it pays for itself, and a restructure must leave
-   every selectable preset loading what it loaded: `snapshot` before the edit, `compare` after it
-   ([shared-bases.md](references/shared-bases.md)).
-4. **Bump the version**, then run the authoring commands in order for each affected bundle, reading
-   every diff and resolving every error before moving on:
-
-   ```bash
-   python3 scripts/orca_profile_tool.py normalize --vendor "<Vendor>"
-   python3 scripts/orca_profile_tool.py update-index --vendor "<Vendor>"
-   python3 scripts/orca_profile_tool.py generate-id --vendor "<Vendor>"
-   python3 scripts/orca_profile_tool.py check
-   ```
-
-   Writing commands accept `--dry-run`. `normalize` changes content and can reformat entire files;
-   rerun `update-index` after any change to `inherits` or `include`, since it orders by them.
-   **Do not use `trim` in this workflow:** it deletes unindexed files, including one you just added. Do
-   not use `normalize --force` for routine edits. An error in a bundle you did not touch predates your
-   change: confirm it on a clean checkout and report it rather than fixing it in the same change.
-5. **Validate:**
-
-   ```bash
-   ./scripts/check_profile.sh --vendor "<Vendor>"   # development loop
-   ./scripts/check_profile.sh                       # full tree before the PR
-   ```
-
-   On Windows use `scripts\check_profile.bat -Vendor "<Vendor>"` / `scripts\check_profile.bat`. Logs
-   land in a per-user cache dir ([validation.md](references/validation.md)). Id checks stay tree-wide
-   under `--vendor`, and filament-only bundles skip the default slice check. Under `--vendor` read only
-   `profile_tool` and `validate_slice`: the other three checks fail on library presets that name other
-   vendors' printers ([why](references/validation.md#the-five-checks)).
-6. **Verify the changed behaviour.** Slice newly added non-default processes and filaments
-   [explicitly](references/validation.md#checking-a-copy-of-the-tree), and
-   [test in the app](references/validation.md#testing-in-the-app) for selection or UI behaviour. Report
-   the checks actually run, their failures and skips, and any hardware tuning still unverified.

-## Symptom → first look

-| Symptom | Start here |
-| --- | --- |
-| A vendor disappears | the app's log or the `validate_system` log; [failure scopes](references/vendor-bundle.md#failure-scopes) |
-| A setting has no effect | key spelling or a legacy name (`PrintConfigDef::handle_legacy`), value type, or a config key placed on a `machine_model` |
-| A preset exists but is not selectable | index registration, `instantiation`, whether it is installed (chosen in the setup wizard, or listed in the model's `default_materials`), compatibility |
-| A filament is missing, duplicated, or matches the wrong spool | [compatibility and alias shadowing](references/filament-profiles.md#compatible_printers), [ids](references/ids.md) |
-| Presets differ only by colour, or an all-printer library preset lacks `@System` | [colour is a runtime property](references/filament-profiles.md#colour-is-a-runtime-property) |
-| High Flow (or a second extruder) slices with Standard (or extruder 1) values; a variant switch is missing; a variant's tuned values never arrive | [extruder variants](references/extruder-variants.md#variant-strings), [widths](references/extruder-variants.md#widths), [variant names](references/validation.md#variant-names) |
-| Values land on the wrong extruder or mode after a variant was added | [inserting a variant](references/extruder-variants.md#adding-a-variant-inserts-its-values-at-its-variant-index), [padding and composition](references/extruder-variants.md#padding-truncation-and-composition) |
-| A resolved value matches neither the file nor its `inherits` parent; an array is not the width the file wrote, or a child got only a base's first value | [composition order and `include`](references/vendor-bundle.md#inherits-and-include) |
-| A bed temperature is ignored | [the twelve plate keys](references/filament-profiles.md#bed-temperature-is-twelve-keys-not-one) |
-| A change is absent from the running app | version bump and [installed profile location](references/validation.md#testing-in-the-app) |
-| A check fails | [error → remedy](references/validation.md#error--remedy) |

-## Source of truth
-
-When this skill and the checkout disagree, the checkout wins: `scripts/orca_profile_tool.py` for the
-tool and its flags; `src/libslic3r/Preset*.cpp` for loading and compatibility;
-`src/libslic3r/PrintConfig.cpp` for keys, types, nullable options, the variant key sets and legacy
-handling; `src/dev-utils/OrcaSlicer_profile_validator.cpp` and `.github/workflows/check_profiles.yml`
-for validation coverage; `docs/HLSD/filament_id.md` for filament identity. The wiki's
-[profile guide](https://github.com/OrcaSlicer/OrcaSlicer_WIKI/blob/main/developer_reference/how_to_create_profiles.md)
-is a tutorial; confirm loader and CLI details against these sources.
-
-## Editing this skill
-
-The skill describes what a profile must be, not what the shipped tree currently is. State rules,
-equations, patterns and profile shapes; never inventories of shipped defects, counts, dated
-measurements or lists of which vendors do what. Test each sentence: if editing the profiles alone,
-with the engine and tool unchanged, could make it false, state the rule behind it or give a generic
-example instead. Example files named as models to copy, and commit hashes cited as the reason for a
-rule, are fine.

-# Extruder variants
-
-Use this when a printer's hotend or extruder can be in more than one hardware configuration that
-needs different settings: a Standard and a High Flow nozzle, a TPU High Flow, E3D High Flow or Extra High Flow nozzle, or
-a Direct Drive and a Bowden extruder on one machine. Variants let one printer, process and filament preset carry a
-separate value per configuration; the user picks the configuration in the sidebar, and slicing uses
-the matching values. They are not for nozzle **diameter**: that stays one `machine` preset per
-`printer_variant`.
-
-## Variant strings
-
-- A **variant string** is `"<extruder_type> <nozzle volume type>"`: the extruder's `extruder_type`
-  value, a space, and its nozzle volume type (the project's `nozzle_volume_type`, seeded by the
-  printer preset's `default_nozzle_volume_type`), e.g. `"Direct Drive High Flow"`.
-- A **variant** is one entry of a preset's variant list, named by its variant string (plus an extruder
-  id for printer and process lists). A variant-aware key holds **one value per variant** (a
-  (normal, silent) pair for the `machine_max_*` limits), and each preset declares its variants in
-  that list. Slicing picks, for each extruder, the variant whose
-  variant string equals the current `extruder_type` + nozzle volume type.
-- Matching is an **exact string compare** of the whole string (plus the extruder id for printer and
-  process lists) against the preset's own resolved list, in any order. With no match the **first
-  variant** is used, silently: variant index 0 for printer and process keys (extruder 1's first
-  variant, whichever extruder asks), the filament's own first variant for filament keys. Printer and
-  process keys are matched only on a printer with several extruders or whose
-  `extruder_variant_list` offers several variant strings (`support_different_extruders`); on any
-  other printer their variant index 0 is read whatever it names. Nothing rejects a profile for a
-  variant mismatch; mistakes surface only as wrong values in the G-code.
-- Variant index and array length follow [Widths](#widths).
-
-The complete enum is `s_keys_map_ExtruderType` and `s_keys_map_NozzleVolumeType` in
-`src/libslic3r/PrintConfig.cpp` (`grep -A5 s_keys_map_NozzleVolumeType` there to confirm):
-
-| Part | Values |
-| --- | --- |
-| Extruder type | `Direct Drive`, `Bowden` |
-| Nozzle volume type | `Standard`, `High Flow`, `TPU High Flow`, `E3D High Flow`, `Extra High Flow` (`Hybrid` exists but is runtime-only) |
-
-So the ten legal variant strings are the two extruder types × the five writable nozzle volume types,
-and this table is the whole test of legality: a string's presence in a shipped profile is no evidence
-for it. `Hybrid` (an extruder with several sub-nozzles) is never a variant: a filament on it reads the
-variant of its own nozzle volume type from the project's `filament_volume_map`, printer and process
-keys get one variant per nozzle volume type the extruder holds (`extruder_nozzle_stats`), and any
-other lookup reads `Standard`. Never write it in a variant string. The same per-filament and
-per-type reading applies on any extruder once `extruder_nozzle_stats` lists more nozzle volume
-types than there are extruders.
-
-Every other string (a nozzle volume type name from another slicer, a typo, a variant copied from a
-shipped profile) is a **dead variant**: nothing selects it, and since lookup is by string it does not
-shift the variants beside it; it still counts toward the variant length when arrays are sized.
-`orca_profile_tool.py check` reports it as an error in every bundle, BBL included
-([variant names](validation.md#variant-names)). Legacy names are errors too: in the four variant
-lists, `default_nozzle_volume_type` and `nozzle_volume_type`, the loader still rewrites `Normal` →
-`Standard` and `Big Traffic` → `High Flow`, so a ported `Direct Drive Normal` variant would load, but
-`check` rejects the spelling and names the enum name to write. `DirectDrive` is rewritten only in
-`extruder_type`, so `DirectDrive Standard` in a variant list is dead. Write the enum names;
-`normalize` does not convert them.
-
-### A nozzle the enum does not name
-
-The nozzle volume types are fixed by the engine, and a profile cannot add one. A nozzle the table does
-not name needs the type added in code first, which is outside profile work; until then any string
-for it is a dead variant. Once the engine has the type, its variant string is the enum name after
-the extruder type, e.g. `"Direct Drive <name>"`, and `check` accepts it with no tool change, since it
-reads the enum from `PrintConfig.cpp`. Existing arrays are unaffected
-([slice time](#slice-time-and-existing-users)).
-
-## When to use variants
-
-| Hardware | Do |
-| --- | --- |
-| One extruder, one nozzle type | Nothing. Without a variant list the printer has one variant ([variant length](#widths)) and no printer-key lookup takes place; a filament with several variants still gets the one for the printer's variant string. |
-| Bowden-only printer | Nothing either. A list-less printer matches no string, so every printer-key lookup reads variant index 0 whether that variant is called `"Bowden Standard"` or `"Direct Drive Standard"`; naming it is cosmetic while it is the printer's only variant. A multi-extruder Bowden printer that declares the layout writes `"Bowden Standard"` variants: `"Direct Drive Standard"` entries match none of its extruders, so every extruder reads variant index 0 (and `check` reports them under [Printer rule 3](#printer-machine)). A filament with a `"Bowden Standard"` variant does get that variant there. |
-| Nozzle types the user swaps (Standard / High Flow / TPU High Flow / E3D High Flow / Extra High Flow) | The printer lists them as variants; tune the keys that really differ per nozzle volume type. |
-| Extruders of different types on one machine | One `extruder_type` per extruder, each extruder listing its own variants. |
-| Several extruders that need different values in a variant key (retraction, z-hop, `nozzle_volume`, the `machine_max_*` limits) | Declare the layout even with a single nozzle volume type: `extruder_variant_list` with one `"<type> Standard"` per extruder, and the flattened pair. Without it the arrays still hold one value per extruder ([variant length](#widths)), but the loader keeps only extruder 1's value of a list-less printer's arrays, so every extruder prints with it. |
-
-A preset without variant keys keeps working on a variant printer: its single variant is applied to
-every extruder. So adding variants to a printer does not break existing processes or library
-filaments; it only makes per-variant tuning possible.

-
-Rules:
-
-1. `extruder_variant_list` has **one entry per extruder**; each entry is the `,`-joined variants that
-   extruder supports. It is the per-extruder menu the sidebar offers. It is in no
-   [variant set](#the-four-key-sets), so the variant-length resize leaves it alone. Extruder 1's
-   first variant, variant index 0 of the flattened pair, is the fallback of every extruder whose
-   variant is missing when the arrays are collapsed for slicing
-   ([slice time](#slice-time-and-existing-users)); it is not necessarily the configuration the user
-   sees, which is `default_nozzle_volume_type` (rule 4).
-2. `printer_extruder_variant` is that list **flattened** extruder-major, one entry per variant, and
-   `printer_extruder_id` gives each entry its 1-based extruder. These two size and address every
-   variant. Write all three keys and keep them in agreement. At load with
-   `single_extruder_multi_material` off, and in the app when the printer tab loads a printer with a
-   different number of extruders, the pair is rebuilt from `extruder_variant_list` (one
-   `Direct Drive Standard` per extruder when the list is absent) and the variant arrays are resized to
-   the rebuilt pair, padded with their first value or cut. The resize skips the `machine_max_*` limits
-   and `hotend_heating_rate` / `hotend_cooling_rate`: they keep their width, and an extruder beyond it
-   reads their first value, so extruder 2 and up of a list-less printer take extruder 1's normal limit
-   as their silent one too. With the three in agreement that changes nothing; a pair written without
-   the list is replaced. A listed variant the pair lacks is a menu choice that reads variant index 0.
-   - The pair without `extruder_variant_list` slices, but the sidebar offers no variant switch and
-     the app cannot add variants to a list-less process: nothing is lost while every extruder
-     has exactly one variant, and every further variant is unreachable.
-   - A missing or one-value `printer_extruder_id` is extruder 1 at every index
-     ([the id trap](#padding-truncation-and-composition)) unless the load-time rebuild above
-     replaces the pair (`single_extruder_multi_material` off).
-   - `check` reports against this rule ([variant arrays](validation.md#variant-arrays)). Errors: a
-     pair that is not the flattening, an id array that does not give each entry its extruder, a list
-     of more than one variant without the pair, and a pair without the list that puts several variants
-     on one extruder. A pair without the list and one variant per extruder is a warning where the
-     load-time rebuild would replace it (`single_extruder_multi_material` off, and a pair other than
-     one `Direct Drive Standard` per extruder), and passes otherwise.
-3. Every variant string in an entry must start with that extruder's `extruder_type`.
-4. `default_nozzle_volume_type` has one value per extruder and must name a nozzle volume type that
-   extruder's variants list; it seeds the sidebar. The live choice is `nozzle_volume_type` in the
-   project config, never a preset key.
-5. Size every array by the set its key belongs to (the three sets are listed in full in
-   [The four key sets](#the-four-key-sets); the lengths are worked through in the
-   [sizing equation](#sizing-equation)): exactly the length below in each selectable preset that
-   writes it, or leave the key out and the preset takes what reaches it, the default or its base's
-   array. One value is no
-   shorthand for "the same for every variant"; write the value for every variant:
-
-| Set | Length | Keys |
-| --- | --- | --- |
-| `printer_extruder_options` | extruders (`E`) | the 8 per-extruder keys outside the variant scheme (`extruder_type`, `nozzle_diameter`, `default_nozzle_volume_type`, …) |
-| `printer_options_with_variant_1` | variant length (`S`) | the full list below; not guessable from names |
-| `printer_options_with_variant_2` | 2 × variant length | the 16 `machine_max_*` limits, at [stride 2](#widths): a (normal, silent) pair per variant |
-
-Put the variant layout on the shared base of all printers that share the hardware, and let the
-nozzle-diameter siblings inherit it, restating only the variant arrays whose values change. `check`
-does not judge a base on its own; its arrays count where they reach a selectable preset, under
-`check --strict`. The loader stores a base at its **own** `printer_extruder_variant`, one variant
-when it writes none whatever its extruder count, and cuts a wider array to its first values before
-any child inherits it; so a multi-extruder base whose extruders need different values declares the
-layout itself ([composition](#padding-truncation-and-composition)). When a variant array can move from
-the presets to a base is in [shared-bases.md](shared-bases.md#variant-arrays-on-a-base).
-
-## Process
-
-1. `print_extruder_variant` + `print_extruder_id` list the (extruder id, variant string) pairs of the
-   process's variants. A variant is found by that pair, never by position: what is **required** is
-   that every pair a compatible printer (by list or condition) can select is present, in any order. A
-   missing pair reads the process's variant index 0 for that extruder, an extra pair is a variant
-   nothing selects, and neither is reported. The exception is a single-extruder printer whose
-   `extruder_variant_list` offers one variant string: no pair is matched there and variant index 0
-   is read, so a process shared with such a printer lists that printer's pair first. **Mirroring** the printer's `printer_extruder_variant` +
-   `printer_extruder_id` entry for entry is the convention; follow it, so the arrays compare by eye,
-   but a different order with every pair present is a nit, not a defect. A process shared by printers
-   whose pairs differ falls back to variant index 0 on the pairs it lacks; give each layout its own base.
-2. Every key in `print_options_with_variant` ([the full list](#the-four-key-sets), which is not
-   "every speed") has exactly one value per variant, or is left out. `print_extruder_id` needs its
-   value per variant too: one value pads to extruder 1 everywhere. `check` holds a
-   `print_extruder_id` that reaches the preset, written or inherited, to one entry per variant on any
-   printer, without `--strict`, and warns when it is absent and a variant repeats.
-3. Only add process variants if speeds or accelerations really differ per nozzle volume type or
-   extruder. Otherwise omit the variant keys: a one-variant process needs no list, because match and
-   no-match both read variant index 0, and that variant is copied to every extruder at slice time.
-4. Put the lists on the process base for that printer layout, so leaves stay small.

-## Filament
-
-```json
-"filament_extruder_variant":     ["Direct Drive Standard", "Direct Drive High Flow"],
-"filament_max_volumetric_speed": ["21", "29"],
-"filament_flow_ratio":           ["0.98", "0.98"],
-"filament_retraction_length":    ["nil", "0.4"]
-```
-
-1. `filament_extruder_variant` lists variants **without extruder ids**: a filament's High Flow variant
-   is used on whichever extruder is in High Flow. Its entries must be distinct, since the lookup
-   returns the first equal string and a repeated entry is a variant nothing selects. There is no
-   filament id key: `filament_extruder_id` exists only as a G-code placeholder, not as a filament
-   option (its option and its set entry are commented out in `PrintConfig.cpp`), so a filament file that writes it loses the key as unknown.
-   `filament_extruder_compatibility` is unrelated to variants (it says which extruders the filament
-   may be loaded into).
-2. Every key in `filament_options_with_variant` ([the full list](#the-four-key-sets)) that reaches the
-   preset, whether written, included or inherited, is resized to its variant count: write it at exactly
-   that width, or leave it out. Keys outside the set
-   (`filament_type`, plate temperatures, `fan_max_speed`, `slow_down_min_speed`, …) are never addressed by variant index; the preset contributes their first value however wide a
-   file writes them.
-3. Cover every variant the material is meant to print on across its `compatible_printers`. Leave out
-   a variant deliberately when the material should not be tuned for it (e.g. a TPU High Flow variant
-   only on TPU filaments); an extruder reporting that variant string then reads the first variant.
-4. Order the variants like the printer's, Standard first, so the first-variant fallback is the
-   conservative one.
-5. Tune what really differs: `filament_max_volumetric_speed` is the usual difference between nozzle
-   volume types, then flow ratio, temperature and retraction. Use measured values; never copy the
-   Standard value into the High Flow variant and call it tuned.
-6. `nil` is legal per variant in the nullable override keys, occupies one entry like any value, and
-   keeps the printer's value for that variant only.
-7. Declare a multi-variant list with the arrays it sizes: on the filament, in its own file or in a
-   template it pulls in with [`include`](vendor-bundle.md#inherits-and-include). The filament may be
-   compatible with printers that list fewer variants, or none: each printer takes the filament's variant
-   for its own variant string, else the filament's first variant. A one-variant list on a shared base
-   is harmless, because one variant is the width a list-less preset has anyway; and a list-less base is
-   stored at that width, so a wider array on it reaches its children as its first value only.
-   A key such a base writes reaches a multi-variant child as one value, which the loader spreads over
-   the child's variants; `check --strict` reports it at the child, which restates it at its own width.
-
-## Widths
-
-Every variant key is a flat array addressed by **variant index**: index `n` belongs to entry `n` of
-the preset's own variant list (`printer_extruder_variant`, `print_extruder_variant` or
-`filament_extruder_variant`). The index is found by exact compare of the string
-`"<extruder_type> <nozzle volume type>"` (plus the 1-based extruder id for printer and process lists),
-and the value is read at `index × stride`:
-
-| Stride | Keys | Layout |
-| --- | --- | --- |
-| 1 | `printer_options_with_variant_1`, `print_options_with_variant`, `filament_options_with_variant` | `[variant 0, variant 1, …]` |
-| 2 | `printer_options_with_variant_2` (the `machine_max_*` limits) | `[variant 0 normal, variant 0 silent, variant 1 normal, variant 1 silent, …]` |
-
-So a variant array is `variant length × stride` long. The **variant length** is the number of
-entries in the preset's variant list, counted on the preset's config **after** `include` and
-`inherits` are applied, dead variants included. An inherited array arrives already resized to the
-base's own variant length, an included one at the width its file wrote
-([composition](#padding-truncation-and-composition)):
-
-| Preset | Variant length |
-| --- | --- |
-| `machine` | `len(printer_extruder_variant)`; without it, the variants `extruder_variant_list` offers; without both, **one per extruder** (`len(nozzle_diameter)`), since the list's default is one `Direct Drive Standard` per extruder. `extruders_count` is a printer-tab field, not a preset key. The loader honours that default only halfway for a system preset: it sizes the composed preset by the one-entry default `printer_extruder_variant`, cutting every variant array to its first value, and only then (with `single_extruder_multi_material` off) rebuilds the pair to one variant per extruder ([Printer rule 2](#printer-machine)) and pads the arrays with that value. The rule's width is still one per extruder; to give extruders different values, declare the layout. |
-| `process` | `len(print_extruder_variant)`; without one, 1 |
-| `filament` | `len(filament_extruder_variant)`; without one, 1 |
-
-The per-extruder keys in `printer_extruder_options` ([listed with the sets](#the-four-key-sets)) are
-outside this scheme and stay one value per extruder. Keys outside [the four sets](#the-four-key-sets)
-are never variant-resized or addressed by variant index, however wide a shipped file writes them; a
-per-extruder vector holds `len(nozzle_diameter)` values, and a shorter one acts as padded with its
-first value ([machine-profiles.md](machine-profiles.md#multi-extruder-idex-and-tool-changers)).
-
-### Sizing equation
-
-For a key in one of the four variant sets:
-
-```
-E    = extruders                        = len(nozzle_diameter) = len(extruder_type)
-                                        = len(default_nozzle_volume_type) = len(extruder_variant_list)
-V_i  = variants listed for extruder i   = ","-separated entries of extruder_variant_list[i],
-                                          each "<extruder_type[i]> <nozzle volume type>"
-S    = variant length                   = V_1 + V_2 + … + V_E
-                                        = len(printer_extruder_variant) = len(printer_extruder_id)
-k    = stride                           = 2 for printer_options_with_variant_2, else 1
-
-N    = values the key holds, one per variant:
-       machine  (printer_options_with_variant_1, _2) = S × k
-       process  (print_options_with_variant)         = len(print_extruder_variant) = len(print_extruder_id)
-       filament (filament_options_with_variant)      = len(filament_extruder_variant)
-values[s × k + m]                       = variant index s, mode m   (m = 0 normal, m = 1 silent; only m = 0 at stride 1)
-variant index s                         = (printer_extruder_id[s], printer_extruder_variant[s])
-```
-
-`printer_extruder_variant` is not sized by the equation; it defines `S`: it is `extruder_variant_list`
-flattened extruder by extruder, and `printer_extruder_id[s]` is the extruder that index `s` came from.
-A process that mirrors the printer's pairs, as [Process rule 1](#process) asks, has `N = S`; a
-filament lists each variant string it is tuned for once, with no extruder id, so its `N` is its own
-and independent of any one printer: it serves every printer in its `compatible_printers`, and a
-variant string no extruder of a printer reports is simply never read there (a two-extruder printer
-with `S = 7` serves a filament whose `N` is 3, and the filament keeps its 3 on a printer that offers
-two variant strings). The
-pair is what the loader reads, so the equality with the sum holds when the three keys agree, as
-[Printer rule 2](#printer-machine) requires.
-
-A selectable preset that writes a variant key writes it at its own `N`; any other width, one value
-included, is an error. A preset that leaves a key out takes what reaches it, the default or an array
-it inherits or includes, which the loader resizes to the preset's `N`; `check --strict` holds that
-array to the preset's `N` too. A base is not judged on its own: its arrays count only where they reach
-a preset that does not override them. BBL is the model for strict: every printer-specific machine,
-process and filament declares its layout and restates every variant key at its own `N`, even where all
-the values are the same, keys Orca added to the sets included.
-Without the lists, `extruder_variant_list` defaults to one
-`Direct Drive Standard` per extruder, so a machine has `V_i = 1` and `S = E`, and a process or filament
-has `N = 1`; the loader cuts a list-less machine to its first variant and, with
-`single_extruder_multi_material` off, widens it again with that value ([variant length](#widths)). The per-extruder keys outside the sets
-(`printer_extruder_options` plus `extruder_offset` and `extruder_colour`) and `extruder_variant_list`
-itself hold `E` values.
-
-### Sizing examples
-
-**One extruder, two nozzle volume types**: `E = 1`, `V_1 = 2`, so `S = 2`; stride-1 keys hold 2
-values, `machine_max_*` hold 4:
-
-```json
-"nozzle_diameter":            ["0.4"],
-"extruder_type":              ["Direct Drive"],
-"extruder_variant_list":      ["Direct Drive Standard,Direct Drive High Flow"],
-"printer_extruder_id":        ["1", "1"],
-"printer_extruder_variant":   ["Direct Drive Standard", "Direct Drive High Flow"],
-"default_nozzle_volume_type": ["Standard"],
-"retraction_length":          ["0.8", "1.0"],
-"machine_max_speed_x":        ["500", "200", "600", "250"]
-```
-
-The matching process lists the same two pairs (`print_extruder_id` `["1", "1"]`,
-`print_extruder_variant` as above) and holds 2 values per key, e.g. `outer_wall_speed`
-`["200", "260"]`; a filament for it lists `["Direct Drive Standard", "Direct Drive High Flow"]` and
-holds 2 values per key, e.g. `filament_max_volumetric_speed` `["16", "24"]`.
-
-**Four extruders, one nozzle volume type each** (a tool changer): `E = 4`, every `V_i = 1`, so
-`S = 4`; stride-1 keys hold 4 values, `machine_max_*` hold 8:
-
-```json
-"nozzle_diameter":            ["0.4", "0.4", "0.6", "0.4"],
-"extruder_type":              ["Direct Drive", "Direct Drive", "Direct Drive", "Direct Drive"],
-"extruder_variant_list":      ["Direct Drive Standard", "Direct Drive Standard",
-                               "Direct Drive Standard", "Direct Drive Standard"],
-"printer_extruder_id":        ["1", "2", "3", "4"],
-"printer_extruder_variant":   ["Direct Drive Standard", "Direct Drive Standard",
-                               "Direct Drive Standard", "Direct Drive Standard"],
-"default_nozzle_volume_type": ["Standard", "Standard", "Standard", "Standard"],
-"retraction_length":          ["0.8", "0.8", "1.2", "0.8"],
-"machine_max_speed_x":        ["500", "200", "500", "200", "500", "200", "500", "200"]
-```
-
-The (normal, silent) pair is repeated per extruder: `["500", "200"]` would be width 2 against
-`S × k = 8` (the loader pads it to `500, 200, 500, 500, …`) and `["500"]` width 1; both are errors. The
-process mirrors the four pairs (`print_extruder_id` `["1", "2", "3", "4"]`) with 4 values per key, or
-omits the variant keys altogether when nothing differs per extruder (then one value per key). A
-filament for it lists only `["Direct Drive Standard"]`: one entry, so one value per key. Drop the
-layout from this printer and the widths stay the same, since the default list gives `S = E = 4`; but
-the loader then keeps only the first variant ([variant length](#widths)): `retraction_length`
-becomes `0.8` on every extruder and extruder 3 loses its `1.2`.
-
-### Adding a variant inserts its values at its variant index
-
-Indexes run extruder-major: extruder 1's variants in `extruder_variant_list` order, then extruder
-2's. A new variant's values go in at its index, not at the end. Giving extruder 1 of a two-extruder
-printer a High Flow option, when only extruder 2 had one:
-
-| Key | Before | After |
-| --- | --- | --- |
-| `extruder_variant_list` | `["Direct Drive Standard", "Direct Drive Standard,Direct Drive High Flow"]` | `["Direct Drive Standard,Direct Drive High Flow", "Direct Drive Standard,Direct Drive High Flow"]` |
-| `printer_extruder_id` | `["1", "2", "2"]` | `["1", "1", "2", "2"]` |
-| `printer_extruder_variant` | `[Standard, Standard, High Flow]` | `[Standard, High Flow, Standard, High Flow]` (full strings in the file) |
-| `retraction_length` (stride 1) | `["0.8", "1.0", "1.2"]` | `["0.8", "?", "1.0", "1.2"]`: one value at index 1 |
-| `machine_max_speed_x` (stride 2) | `["500", "200", "600", "250", "700", "300"]` | `["500", "200", "?", "?", "600", "250", "700", "300"]`: a (normal, silent) pair at position 2 |
-| `print_extruder_id` / `print_extruder_variant` / `outer_wall_speed` | mirror the printer | the same insertion at index 1 |
-| `filament_extruder_variant` `[Standard, High Flow]` | — | unchanged: filament variants carry no extruder id, so the existing High Flow variant now serves both extruders |
-
-Every `?` is a measured value for that nozzle, on the machine limits as much as on retraction.
-Removing or renaming a variant shifts the later values the same way in reverse; a variant string that
-no longer matches the enum is simply a variant nothing selects.
-
-### Padding, truncation and composition
-
-**Every key in the set widens, whether or not a file restates it.** At load each variant key of the
-composed config is resized to the length of the preset's own `*_extruder_variant` (the one-entry
-default when it writes none) × stride: a short array is **padded by repeating its first value**, a
-long one is truncated to its first values, without a word from the loader or the validator. The rule
-does not follow from this padding: a file writes a variant key at **exactly `variant length × stride`**
-or not at all. Any other length, one value included (which the loader spreads over every variant, at
-stride 2 over normal *and* silent alike), is a mistake the loader hides and
-`orca_profile_tool.py check` reports as an error in the selectable preset that writes it, even when
-every value is the same; `check --strict` also reports an array that reaches a selectable preset at
-another width
-([variant arrays](validation.md#variant-arrays)).
-
-The loader sizes a list-less preset of any type to one variant at this step, a list-less machine
-included: a two-extruder machine without a layout that writes `retraction_length` `["0.8", "0.9"]`, the
-width the equation asks for, stores `["0.8"]`, which the pair rebuild and the slice-time collapse hand
-to both extruders. A 3-value array on a preset of variant length 2 keeps its first two; at length 4 it
-becomes `[a, b, c, a]`.
-
-Composition hands down widths in two ways:
-
-- **`inherits` hands down the parent's resized arrays.** A base is stored after its own resize, at
-  the length of its own `*_extruder_variant` (one variant for a base of any type that writes none,
-  whatever its extruder count), so an array wider than the base's list is cut to its first values
-  before any child sees it, and a child that adds variants gets those first values padded. Widen an
-  array only on a preset whose own resolved list already has the entries. `check` judges selectable
-  presets only, at the width each file wrote: an array a base's own resize cuts is not seen (a review
-  item), and an inherited array of another width than a child's list is left to the loader's resize
-  unless `check --strict`, which asks the child to restate it at its own width.
-- **`include` hands down the template's diff at its pre-resize width.** The template contributes every
-  key where its composed config differs from the built-in defaults, taken before its own resize, so the
-  arrays it writes arrive at the width its file wrote, and the includer's own list sizes them. A key the
-  template sets to the built-in default is not passed on
-  ([`include`](vendor-bundle.md#inherits-and-include)).
-
-The id keys are the trap in this padding: `printer_extruder_id` and `print_extruder_id` are members
-with default `[1]`, so a missing or one-value id array beside a longer variant list is padded to
-extruder 1 at every index. That is right on a single-extruder printer and wrong on a multi-extruder
-one, where every variant is then addressed as extruder 1's. A machine escapes it only where the
-load-time pair rebuild of [Printer rule 2](#printer-machine) runs (`single_extruder_multi_material`
-off); a process's `print_extruder_id` is never rebuilt at load. `check`
-holds an id array that reaches a selectable preset, written or inherited, to one entry per variant on
-any printer; `fix-variant` never pads an id array or a variant list, since those address the
-variants rather than fill them.
-
-Consequences:
-
-- A base that gains a variant silently pads every descendant that restates a variant array at the old
-  width, and a short `machine_max_*` array copies variant 0's *normal* limit into the silent entries
-  too; a descendant that restates nothing inherits the widened array and needs no edit. Extend, in one
-  change: the printer base and each nozzle-diameter sibling that restates a variant array, the process
-  bases that mirror the printer's variants, and the filaments that should cover the variant.
-- A one-value override is reported, and the loader spreads it over **all** variants, overwriting the
-  ones that should differ.
-- A process or filament that omits the new variant is not padded; the variant resolves to its index 0.
-
-### Slice time and existing users
-
-**Slice time collapses variants to extruders.** When printer, process and filaments are combined on a
-printer with several extruders or several variant strings, each printer and process variant key is
-re-gathered to one entry per extruder (× stride) in extruder order, using each extruder's live nozzle
-volume type, or to one entry per nozzle volume type for an extruder that holds several (Hybrid, or
-`extruder_nozzle_stats` listing more types than there are extruders); on any other printer they are
-not re-gathered and variant index 0 is read. Filament keys are re-gathered to one entry per filament,
-on a printer with a single variant too once a filament has several variants, and under a dynamic
-nozzle map to one entry per variant each filament prints through. Custom G-code and the
-`machine_max_*` limits therefore index by extruder or filament, never by variant index; variant order
-matters only inside the preset. An extruder with no matching variant reads variant index 0, extruder
-1's first variant, whichever extruder it is; under layered nozzle grouping, `get_config_index_base`
-reads the collapsed arrays and falls back to the same extruder's first entry instead.
-
-**Existing user presets and projects follow the variant string, not the position.** A user preset
-stores every variant array it changed (nullable keys as per-variant diffs, `nil` where equal to the
-parent). On load each parent variant takes the child's value for the variant with the same extruder id
-and variant string; variants the parent gained keep the parent's value, and a child whose arrays the
-parent cannot map keeps its own. Per-object process overrides are remapped when a printer change
-alters the extruder count or the length of `printer_extruder_variant`, by variant string alone (no
-extruder id; of several matching values the smallest wins), and a single-value override applies to
-every variant. Adding or reordering variants in a shipped preset is therefore safe for existing
-users; renaming a variant, or moving it to another extruder id, loses their values for it.
-
-**A new nozzle volume type changes no array.** Adding one to the code widens nothing until a profile
-lists the new variant string; until then every existing array keeps its length and meaning.
-
-## The four key sets
-
-Membership is literal (four `std::set<std::string>` initializers in `src/libslic3r/PrintConfig.cpp`)
-and **not guessable from names**: `ironing_speed`, `skirt_speed`, `wipe_speed`, `scarf_joint_speed`,
-`small_support_perimeter_speed` and `wipe_tower_max_purge_speed` are process speeds outside the set,
-while every process `*_acceleration` and `*_jerk` key is inside, and so are
-`small_perimeter_threshold`, `top_solid_infill_flow_ratio` and `slowdown_for_curled_perimeters`;
-`filament_flush_temp` is in and `filament_flush_temp_fast` out; `use_firmware_retraction` is out and
-`travel_slope` and `retract_lift_enforce` in. The three variant-list keys and the two id
-keys are members of their own set (the list sizes itself, a no-op; the id keys are padded like any
-other member, [the id trap](#padding-truncation-and-composition)), while `extruder_variant_list` is in
-no set: the variant-length resize leaves it alone, and only the pair rebuild of
-[Printer rule 2](#printer-machine) pads it. The per-extruder `printer_extruder_options` is listed
-last for contrast; it is not a variant set.
-
-`check` and `fix-variant` read the four sets from `PrintConfig.cpp` on every run, so they follow the
-engine. The lists below are from the 2026-09-29 checkout; regenerate them from the repository root
-before relying on them (the recipe strips comments, since an initializer can carry a commented-out entry):
-
-```bash
-python3 - <<'EOF'

-entries beyond the extruder count are never read
-([per-extruder vectors](machine-profiles.md#multi-extruder-idex-and-tool-changers)).
-
-## Checking and testing
-
-Checklist for a new variant profile set:
-
-1. Decide the variants per extruder from the real hardware; pick legal strings only.
-2. Printer base: `extruder_type`, `extruder_variant_list`, flattened `printer_extruder_variant` +
-   `printer_extruder_id`, `default_nozzle_volume_type`; every variant array at variant length, every
-   `machine_max_*` at 2 × variant length as (normal, silent) pairs, even where the values are the
-   same, values in variant order.
-3. A process base per variant layout, or no variant keys at all.
-4. Filaments for the printer: a variant list covering the intended variants, every variant key at that
-   width, measured values per nozzle volume type.
-5. Run the usual authoring commands and full checks. `check` holds each array of steps 2–4 to the
-   width of the selectable preset that writes it, `check --strict` also to every selectable preset it
-   reaches, and
-   the printer's layout keys through every selectable preset
-   ([variant arrays](validation.md#variant-arrays)); `check_variant_names` holds every variant string,
-   `extruder_type`, `nozzle_volume_type` and `default_nozzle_volume_type` to the enums
-   ([variant names](validation.md#variant-names)). The choice of variants, the variant order and
-   the measured values are not checked.
-6. In the app, for each nozzle volume type in the sidebar combo: slice and confirm the G-code uses that
-   variant's values (e.g. volumetric speed limit, retraction). `validate_slice` only slices the default
-   nozzle volume type.
-
-To review rather than author, run the same list against the diff. `check` catches a wrong array length,
-a layout key out of step, and a variant string the enums cannot build. The failures no check catches: a
-new variant appended instead of inserted at its index, an array widened on a base whose list is
-shorter (cut before any child inherits it), a process lacking a pair its printer can select, and a High
-Flow variant copied from Standard.
-
-### UI facts to design around
-
-- The single-extruder sidebar shows a **nozzle volume type combo** (tooltip `Flow`, in place of the
-  nozzle-diameter selector) only when `extruder_variant_list` offers more than one distinct variant
-  string (`support_different_extruders`); four extruders listing `Direct Drive Standard` each show
-  none.
-- The two-extruder sidebar's per-extruder nozzle volume type combos are shown for BBL printers only.
-  Another vendor's multi-extruder printer falls back to the single-extruder layout: one combo (for the
-  first extruder) when the variants differ, otherwise the nozzle-diameter selector, so the other
-  extruders' nozzle volume type stays at `default_nozzle_volume_type`.
-- High Flow is hidden from the combo when `printer_variant` is `0.2` or the printer model is
-  `Bambu Lab X1E`, and E3D High Flow unless `printer_variant` is `0.4` or `0.6`. A variant listed on
-  another nozzle diameter is never selectable there.
-- The filament tab shows a variant switch built from the filament's own `filament_extruder_variant`;
-  a multi-variant filament whose tab shows none did not resolve its variant list through `include` or
-  `inherits`. The printer and process tabs show one entry per extruder instead, labelled with that
-  extruder's live nozzle volume type (two for Hybrid), and only on two-extruder printers whose
-  `extruder_variant_list` offers more than one variant string; elsewhere they edit the variant of the
-  nozzle volume type selected in the sidebar (an X1C shows no switch).
-
-### Worked examples in the tree
-
-`BBL/machine/fdm_bbl_3dp_001_common.json` (one extruder), `fdm_bbl_3dp_002_common.json` (two
-extruders), `Bambu Lab X1 Carbon 0.4 nozzle.json` (Standard + High Flow), `Bambu Lab H2D 0.4
-nozzle.json` (extruders with different variant sets), `Bambu Lab X2D 0.4 nozzle.json` (Direct Drive +
-Bowden), with their `@BBL` processes and filaments. The H2D and X2D examples also carry
-`E3D High Flow` variants. BBL's multi-variant filament lists come from `fdm_filament_template_*`
-presets that the printer-specific filaments pull in with `include`, not from their `inherits` chain.

-# Filament profiles and OrcaFilamentLibrary
-
-`OrcaFilamentLibrary` is the filament-only bundle the loader reads **first**, so any vendor's filament may
-inherit a library preset by name. It is the only cross-bundle parent: vendor-to-vendor inheritance
-always fails.
-
-## Where a filament goes
-
-| Contribution | Location |
-| --- | --- |
-| Generic material for all printers | `OrcaFilamentLibrary/filament/Generic <mat> @System.json` |
-| A brand's product, all printers | `OrcaFilamentLibrary/filament/<Brand>/` |
-| A brand's tune for one printer vendor | `OrcaFilamentLibrary/filament/<Brand>/<PrinterVendor>/` (recommended); `<PrinterVendor>/filament/<Brand>/` also works |
-| A printer vendor's tune of a generic, or its own product | `<PrinterVendor>/filament/` |
-
-Both locations in the third row are supported: `OrcaFilamentLibrary/filament/<Brand>/<PrinterVendor>/<Name>.json`
-(the shape the wiki shows) and `<PrinterVendor>/filament/<Brand>/`. The library path is the one a
-filament brand should contribute to: `OrcaFilamentLibrary/filament/<Brand>/` is the brand's own folder,
-while a printer vendor's folder belongs to that printer vendor.
-
-Library layout: `filament/base/fdm_filament_*.json` material roots, root-level
-`Generic <mat> @System.json` generics, and one subfolder per brand, which may nest printer-specific
-tunes one level deeper. Adding a brand means adding a folder here; the folder name is a directory label
-only, and `filament_vendor` inside the JSON is the real vendor string.
-
-## The three-part shape
-
-```jsonc
-// OrcaFilamentLibrary/filament/Polymaker/Fiberon PA6-CF @base.json — the product root: identity + material values
-{ "type": "filament", "name": "Fiberon PA6-CF @base", "from": "system",
-  "instantiation": "false", "inherits": "fdm_filament_pa",
-  "filament_id": "OFkOviHk",                 // minted here by generate-id; every child inherits it
-  "filament_vendor": ["Polymaker"], "filament_type": ["PA6-CF"], /* … */ }
-
-// OrcaFilamentLibrary/filament/Polymaker/Fiberon PA6-CF @System.json — the selectable all-printer shim, 7 keys
-{ "type": "filament", "name": "Fiberon PA6-CF @System", "from": "system",
-  "instantiation": "true", "inherits": "Fiberon PA6-CF @base",
-  "setting_id": "…", "compatible_printers": [] }
-
-// BBL/filament/Polymaker/Fiberon PA6-CF @BBL X1C.json — a printer tune (BBL keeps its own copy of the @base)
-{ …, "inherits": "Fiberon PA6-CF @base", "filament_max_volumetric_speed": ["14"],
-  "compatible_printers": ["Bambu Lab X1 Carbon 0.4 nozzle", …] }
-```
-
-- `@base` is the convention for a root; a root is really `instantiation: "false"`. A base carries
-  **no** `setting_id`, no `compatible_printers` and no `filament_settings_id`. Only the `setting_id`
-  half is enforced; the other two are unchecked, so a neighbouring base that carries them is no model.
-- Every `@System` shim must be `"instantiation": "true"`; one set to `"false"` would ship but could
-  never be selected, and no check catches it. The shim exists only for products in the library.
-- `filament_cost`, `filament_density`, `filament_type` and `filament_vendor` belong on the root and
-  should not appear in a printer tune.
-- A brand `@base` duplicated across bundles is legal (a vendor bundle may keep its own copy of a
-  library product root, with the same id): bases never become selectable presets and the
-  duplicate-name error covers only those, so there is none.
-- You may inherit from an instantiated preset as well as from a base.
-
-## Colour is a runtime property
-
-`filament_id` identifies a product, not a colour; filament sync and AMS read the colour from the spool
-at runtime. A product ships one all-printer preset and the colour is chosen at runtime, never a sibling
-preset that differs only by colour. A material family (PLA vs PLA Matte vs PLA Silk) is a new product;
-a colour is not. A printer tune keeps the product alias and does not multiply per colour either.
-
-CI does not catch this (per-colour presets pass `check`), so it is a review call.
-
-## The two most common contributions
-
-**A printer vendor tuning a generic.** Keep the `Generic X` alias so it shadows the library preset on
-your printers, inherit `Generic X @System`, declare **no** `filament_id` (inheriting the library's is
-correct: the product really is the library's generic), and give it a non-empty `compatible_printers` in
-its own file:
-
-```jsonc
-// <Vendor>/filament/Generic PETG @Acme One 0.4 nozzle.json
-{ "type": "filament", "name": "Generic PETG @Acme One 0.4 nozzle", "from": "system",
-  "instantiation": "true", "inherits": "Generic PETG @System",
-  "filament_flow_ratio": ["0.95"], "filament_max_volumetric_speed": ["10"],
-  "compatible_printers": ["Acme One 0.4 nozzle"] }
-```
-
-**A printer vendor's own branded product.** Give it a `@base` root on a material base so `generate-id`
-can mint the id, then one instantiated leaf per printer in the same bundle. Inheriting
-`Generic X @System` directly gives the product the generic's id, which the tool cannot fix
-([ids.md](ids.md#what-generate-id-does-and-does-not-fix)). No `@System` shim: that is only for a product
-entering OrcaFilamentLibrary.
-
-```jsonc
-// <Vendor>/filament/Acme Aura PETG @base.json — instantiation false, no setting_id
-{ "type": "filament", "name": "Acme Aura PETG @base", "from": "system",
-  "instantiation": "false", "inherits": "fdm_filament_pet",
-  "filament_vendor": ["Acme"], "filament_type": ["PETG"] }   // filament_id minted here
-
-// <Vendor>/filament/Acme Aura PETG @Acme One 0.4 nozzle.json
-{ "type": "filament", "name": "Acme Aura PETG @Acme One 0.4 nozzle", "from": "system",
-  "instantiation": "true", "inherits": "Acme Aura PETG @base",
-  "filament_max_volumetric_speed": ["11"],
-  "compatible_printers": ["Acme One 0.4 nozzle"] }
-```
-
-Omit `filament_settings_id` from new presets: it is runtime bookkeeping the app rewrites to the preset
-name.
-
-To offer either kind by default, add its name to each model's `default_materials`; put it first in the
-machine's `default_filament_profile` only if it should be the preselected filament
-([machine keys](machine-profiles.md#other-keys)).
-
-## `compatible_printers`
-
-- **Library fallbacks** (`@System`): empty `[]` or absent, so they are offered on all printers except
-  where [alias shadowing](#alias-shadowing) supplies a printer-specific tune.
-- **Library printer-specific tunes**: non-empty, listing exact printer **variant** names. These
-  supersede a same-alias fallback just like a tune in a printer vendor's bundle.
-- **Instantiated filaments in every other vendor**: non-empty, listing exact printer **variant** names.
-  Enforced twice, but not identically: `validate_system` reads the resolved config, so an inherited list
-  satisfies it, while `check` reads the file's **own** key. Write the list in the file itself. This is
-  the most common filament CI failure.
-- Emptying it to "make it apply everywhere" fails that check *and* collides with the library generic's
-  `filament_id` on every printer.
-- Copying a base's full printer list onto a nozzle-specific tune produces duplicate combobox entries: a
-  real shipped bug twice over.
-
-## Overlapping coverage: one variant, one profile per product
-
-`filament_id` is the **product** key, not the preset key: every preset of one product shares it
-(`<filament_vendor>/<filament_type>/<alias>`). So if one printer variant appears in the
-`compatible_printers` of two presets of that product, the slicer cannot tell them apart at AMS match
-time. `validate_system` reports `Ambiguous AMS filament match: N filament presets share filament_id "X"
-and are all compatible with printer "Y"`; `orca_profile_tool.py check` does **not** see it and passes.
-Resolve the overlap by **specificity**: keep the variant on the most specific profile and remove it from
-every more general one. Deleting a profile is the least preferred fix: moving coverage keeps the tune
-that users rely on.
-
-Judge specificity from the profile's `compatible_printers` (how many variants it actually covers) and
-use the name only as a secondary, often vague hint; decide by the lists, with a judgement call on the
-name. Naming conventions differ by vendor: BBL's is the reference (`@<Vendor> <Model>` for a whole
-model, `@<Vendor> <Model> <nozzle> nozzle` for one variant, `@<Vendor>` for a vendor-wide generic), but
-others vary (`@<printer model>`, a printer serial, or Creality's `@<Model>-all`). A name never overrides
-the list; see [preset naming](naming.md#filament) for the shapes.
-
-Specificity, most to least:
-
-1. **Variant-specialized**: lists a single printer variant (BBL-style
-   `… @<Vendor> <Model> <nozzle> nozzle`).
-2. **Model-specialized**: lists the variants of one printer model (BBL-style `… @<Vendor> <Model>`). It
-   should cover every variant of its model, not only the nozzle it was authored for.
-3. **Family / series**: lists variants spanning a printer family or series.
-4. **Generic / catch-all**: vendor-wide, covering many unrelated models (often the bare
-   `Generic <mat> @<Vendor>`).
-
-Rules:
-
-- A model-specialized profile is extended to **all** variants of its model, and each variant it thereby
-  starts covering is removed from the family and generic profiles that also listed it, including
-  variants that had no overlap before. Apply it per nozzle, not just 0.4.
-- Apply it **per product**: trim only the material that has a specialized profile from the generic; a
-  material whose product has no specialized profile keeps the variant in the generic.
-- Never strip coverage a variant has nowhere else to get. If a variant has no variant-level specialized
-  profile, the next level down keeps it; when the model has specialized profiles, the model-level one
-  wins over the family and generic ones.
-- Moving coverage is preferred over deleting. If a profile must be deleted, remove the more general one,
-  not the specialized profile that carries the tune.
-- After moving coverage, repoint the affected machine's `default_filament_profile` and clean the model's
-  `default_materials`: they should name the most specific profile that covers the variant, and should
-  not keep generic entries that no longer cover the model. This rule applies equally when adding or
-  fixing defaults.
-
-Several profiles of one product with **disjoint** `compatible_printers` is the intended end state.
-Adding coverage to the specialized profile and removing it from the generic is the preferred direction.
-
-**Detection caveat:** `orca_profile_tool.py check` is blind to this; only the validator behind the full
-`./scripts/check_profile.sh` reports it (`validate_system`). Always confirm with that, not the
-vendor-scoped loop.
-
-## Alias shadowing
-
-A printer-specific filament in either the library or a vendor bundle supersedes the library fallback on
-the printers it lists. The matching key is the **alias**: the preset name up to the **first** `@`,
-right-trimmed (no `@` → the whole name). So `QIDI ABS-GF@Q2-Series` aliases to `QIDI ABS-GF`.
-
-A library preset with an empty `compatible_printers` is hidden on every printer that a same-alias preset
-lists in a non-empty `compatible_printers`, whether that preset is in the library or in a vendor bundle
-(a printer matches by its own name or its parent's).
-
-Two consequences:
-
-- **Only an unrestricted library fallback can be shadowed.** Two printer-specific presets sharing an
-  alias do not hide each other; overlapping lists for the same product trip the ambiguous-match error
-  above instead.
-- This is why adding `Generic PLA @<printer>` to a vendor silently removes the library
-  `Generic PLA @System` from that printer. That is intended, and the reason a vendor tuning a generic
-  must **keep the `Generic X` alias**.
-
-The literal spelling `Generic <mat> @System` is load-bearing beyond shadowing: when a user preset, an
-imported preset or a 3MF project names a parent that no longer resolves and contains `Generic`, the
-loader rewrites the name into `Generic <mat> @System` and retries. Only the library ships those names,
-so keep them.
-
-## `filament_id`, `filament_vendor`, `filament_type`
-
-`filament_id` is minted from the triple `(filament_vendor, filament_type, alias)`. `filament_vendor` and
-`filament_type` are therefore **identity, not decoration**: editing either, or the alias, re-mints the
-id. Read `docs/HLSD/filament_id.md` before changing any of them, and see [ids.md](ids.md) for the
-tooling.
-
-A filament with no resolvable `filament_id` anywhere in its `inherits` chain is a **hard load error**
-that discards the vendor bundle. The id inherits across bundles, so a vendor's `Generic ABS @X`
-inheriting `Generic ABS @System` gets the library's id for free; a vendor's own product must resolve its
-own.
-
-- `filament_type` **must be a JSON array**: the one vector key `check` rejects as a scalar outright. A
-  scalar `"PP"` once hung the filament and printer selection UI.
-- It is an **open** enum: an unlisted value is accepted silently and falls back to 190–300 °C defaults
-  and adhesion 1.0. Prefer a value from `MaterialType::all()` in
-  `src/libslic3r/MaterialType.cpp`, or add a row there.
-- Generics use `filament_vendor: ["Generic"]`, which `fdm_filament_common` already defaults to.
-
-## `"nil"`
-
-`"nil"` is legal only in an option defined as nullable (`add_nullable`, or `nullable = true`, in
-`src/libslic3r/PrintConfig.cpp`). Anywhere else it fails the file, and with it the **whole bundle**
-(`Failed loading configuration file`, after `Deserializing nil into a non-nullable object` or
-`Invalid value provided for parameter <key>: nil`). To leave a non-nullable key unset, omit it; do not
-write `nil`.
-
-In filament presets a minority of the `filament_*` keys are nullable, plus `long_retractions_when_ec`
-and `retraction_distances_when_ec`. About half of them are the extruder overrides (`filament_retraction_length`,
-`filament_z_hop`, `filament_wipe`, `filament_retract_*`, `filament_retraction_speed`,
-`filament_deretraction_speed`, `filament_retraction_minimum_travel`, `filament_wipe_distance`,
-`filament_long_retractions_when_cut`, `filament_retraction_distances_when_cut`, …), where `nil` means
-*keep the printer's or extruder's own value*. The rest are ordinary nullable options
-(`filament_flow_ratio`, `filament_flush_temp`, `filament_adaptive_volumetric_speed`, …), where it means
-*unset*. Check the option's definition before writing `nil` anywhere else.
-
-## Tuning per nozzle and per variant
-
-Between a product's `@X` and `@X 0.N nozzle` tunes the keys that usually differ, most often first, are
-`filament_max_volumetric_speed`, `filament_retraction_length`, `slow_down_min_speed`,
-`filament_flow_ratio`, `slow_down_layer_time`, `nozzle_temperature` and `pressure_advance` (switched on
-by `enable_pressure_advance`).
-
-Use measured values for the material, hotend, extruder and nozzle combination. Neither maximum
-volumetric speed nor pressure advance has a universal nozzle-only lookup table. When cloning a 0.4
-preset for a 0.2 nozzle, explicitly revisit flow limits; do not infer a pressure-advance value, or a
-required direction of change, from diameter alone.
-
-On a printer with extruder variants, a filament tunes these per variant too:
-`filament_max_volumetric_speed`, `filament_flow_ratio`, `nozzle_temperature`, pressure advance and the
-retraction overrides carry one value per variant of `filament_extruder_variant` (Standard, High Flow, …). The
-exact key set is [`filament_options_with_variant`](extruder-variants.md#the-four-key-sets);
-`slow_down_min_speed` and `fan_max_speed` are not in it. Keep every such array at exactly that width, even where the
-setting does not differ per variant, and measure the High Flow variant rather than copying Standard
-([extruder-variants.md](extruder-variants.md#filament)).
-
-## Bed temperature is twelve keys, not one
-
-There is no single "bed temperature". The plate type selected for the printer (`Cool Plate`,
-`Engineering Plate`, `High Temp Plate`, `Textured PEI Plate`, `Textured Cool Plate`, `Supertack Plate`)
-picks one of six keys, each with an `_initial_layer` twin: `cool_plate_temp`, `eng_plate_temp`,
-`hot_plate_temp`, `textured_plate_temp`, `textured_cool_plate_temp` and `supertack_plate_temp`.
-
-`textured_cool_plate_temp` is the one most often forgotten. A non-BBL printer with
-`support_multi_bed_types` off hides the plate selector and uses the printer preset's `default_bed_type`
-(High Temp Plate, `hot_plate_temp`, when unset or invalid), but a loaded project or a CLI config can
-still carry another plate. So set every plate the printer plausibly has, as the sibling presets in the
-bundle do.
-
-## Style
-
-- Overrides, not full copies: an instantiated filament preset carries around a dozen non-meta keys,
-  and a library `@System` shim two or three. A preset that restates fifty-plus keys from its parent is
-  the pattern to move away from, not to copy. Commit `6943b6ddc3` is the stated model for converting such presets: flip true
-  bases to `instantiation: "false"`, strip their `compatible_printers`, `setting_id` and
-  `filament_settings_id`, and add `renamed_from` on the surviving selectable preset. A value every
-  printer tune of a product shares goes on the product's `@base`
-  ([shared bases](shared-bases.md#levels)).
-- Prefer the library's `fdm_filament_*` bases over a vendor-local copy; for a new preset, even in a
-  bundle whose older presets use one: a local copy drifts from the library's.
-- Canonical key order, written by `orca_profile_tool.py normalize` when it rewrites a file: `type`,
-  `name`, `renamed_from`, `inherits`, `from`, `setting_id`, `filament_id`, `instantiation`, then
-  everything else in the order you wrote it. Not enforced on its own: a file that leads with
-  `compatible_printers` passes `check`.
-- **Every vector-typed (`co…s`) key must be a JSON array.** Only a scalar `filament_type` is an outright
-  error; `normalize` silently arrayifies five more (`filament_cost`, `filament_density`,
-  `temperature_vitrification`, `filament_max_volumetric_speed`, `filament_vendor`), and `check` fails
-  when it would. Every other vector key is on you, including `filament_start_gcode`,
-  `filament_end_gcode`, `filament_extruder_variant`, `compatible_printers` and the plate temperatures.

-# `setting_id` and `filament_id`
-
-Orca-generated ids are deterministic hashes of identity. **Never invent an id or copy a sibling's
-`setting_id`.**
-Use `scripts/orca_profile_tool.py`; the two special cases are
-[a wrongly inherited filament id](#what-generate-id-does-and-does-not-fix) and
-[BBL's authoritative setting ids](#bbls-exception-precisely).
-
-`docs/HLSD/filament_id.md` is the authoritative design document for `filament_id`: the id landscape,
-the checks CI runs, and the Bambu catalog map. This page is the tooling half.
-
-| | `setting_id` | `filament_id` |
-| --- | --- | --- |
-| Identifies | one selectable preset | one filament **product** |
-| Key hashed | `<vendor folder>/<type>/<name>` | `filament_product/<filament_vendor>/<filament_type>/<alias>`, using the resolved (inherited) first values and the name up to the first `@`, right-trimmed |
-| Shape | 16 base62 characters | `OF` + 6 base62 characters |
-| Required on | every `instantiation: "true"` preset | every **instantiated** filament, own or inherited |
-| Forbidden on | bases (`instantiation` not `"true"`) | — (a product's root base is exactly where it belongs) |
-| Scope | unique across the whole tree | shared by every preset of the product, in every bundle |
-
-`<type>` is `machine`, `process` or `filament`, and the vendor is the **folder** name (`BBL`), not the
-display name (`Bambulab`). Renaming a preset changes its `setting_id`; renaming a filament's alias, or
-editing its `filament_vendor` or `filament_type`, also changes its `filament_id`, and the old id is not
-forwarded.
-
-## The tool
-
-`scripts/orca_profile_tool.py` takes a subcommand:
-
-| Command | Does |
-| --- | --- |
-| `check` | everything CI's `profile_tool` step runs; see [validation.md](validation.md#orca_profile_toolpy-check) |
-| `generate-id` | writes `setting_id` and `filament_id` |
-| `normalize` | rewrites profile files into their canonical shape |
-| `trim` | deletes profile files no `<Vendor>.json` list references |
-| `update-index` | rebuilds the `*_list` sections from the files on disk |
-
-The order after adding, renaming or deleting files is `normalize` → `update-index` → `generate-id` →
-`check`. Each step feeds the next, so it is not interchangeable. The
-[authoring workflow](../SKILL.md#creating-or-modifying-a-profile) has the commands.
-
-> **`trim` deletes.** It removes every profile file the index does not list, including the one you just
-> added and have not registered yet. Register first, or skip `trim` entirely: it is a cleanup sweep, not
-> part of landing a profile. Preview with `--dry-run`.
-
-**Register, then mint.** The `filament_id` pass reads `<Vendor>.json`'s `filament_list`, not the
-filesystem (the `setting_id` pass walks the filesystem, so a bundle whose index has not landed yet is
-still assignable). A new filament file is therefore invisible to `generate-id`'s `filament_id` pass
-until it is registered; its `setting_id` is written regardless.
-
-- `--dry-run` works on every writing command (`generate-id`, `normalize`, `trim`, `update-index`) and
-  writes nothing.
-- `--filament-id` / `--setting-id` narrow `generate-id` to one pass; they exclude each other, and
-  passing neither writes both.
-- `--vendor` is repeatable and narrows **only what is written**: an id is a function of its own key
-  alone, so a narrowed run writes exactly what a full run would. An unknown vendor exits 1 before any
-  write. `--vendor` on `check` narrows the per-vendor checks only; the `setting_id` and `filament_id`
-  passes stay tree-wide.
-- `--profiles DIR` points any command at another tree; see
-  [Checking a copy of the tree](validation.md#checking-a-copy-of-the-tree).
-- `--profile-type` narrows `normalize`, `trim` and `update-index` to `machine_model`, `process`,
-  `filament` or `machine`.
-- Exit codes: 0 clean, 1 errors found (`generate-id` still writes what it could), 2 argparse misuse.
-- Output is ANSI-coloured; searching for the literal `[ERROR]` still works.
-
-`generate-id` is **idempotent and byte-preserving**: BOM and CRLF are kept, and each pass touches only
-its one key line. A legitimate `generate-id` diff is one or two changed lines per file: a new instantiated
-filament gets both a `filament_id` and a `setting_id`. `normalize` is the opposite by design (it
-rewrites whole files into canonical shape), which is why `check` demands it already be a no-op. A file
-committed with CRLF line endings changes on every line under `normalize`; read the diff before
-committing it.
-
-Exit 1 from `generate-id` does not mean nothing was written: it writes every id it can and reports the
-rest, so read the diff before rerunning. On a clean tree `check` and `generate-id --dry-run` both exit 0
-with zero findings; that is the baseline to restore before opening a PR.
-
-## What `generate-id` does and does not fix
-
-Writes:
-
-- a `setting_id` into any instantiated preset that lacks one, or whose value does not match the formula;
-- strips a `setting_id` from a base;
-- deletes the misspelled key `settings_id`, moving its value to `setting_id` only on an instantiated BBL
-  preset that lacks one (everywhere else the old value is discarded and a fresh id minted);
-- a `filament_id` into the id-less **root(s)** of an instantiated filament that resolves none;
-- rewrites a **declared** `filament_id` that is not the mint of its own triple.
-
-Refuses to write (reports only): a base62 collision between two products, an empty `filament_vendor` or
-`filament_type`, a broken `inherits` chain, and roots of one filament resolving different
-`(filament_vendor, filament_type)` pairs.
-
-**Does not fix: a preset that *inherits* a wrong `filament_id`.** This is check 2b (the label `docs/HLSD/filament_id.md` and the tool use), and it is the trap most likely to bite.
-It happens when a branded filament inherits a generic for its settings:
-
-```jsonc
-{ "name": "Phrozen Aura PETG @Phrozen Arco 0.4 nozzle",
-  "inherits": "Generic PETG @System" }   // resolves the library generic's id: wrong product
-```
-
-The preset resolves *an* id, so `generate-id` neither inserts nor rewrites one, and `check` fails with
-`inherits filament_id "X" but its own triple "V/T/N" mints "Y"`.
-
-Two fixes, in order of preference:
-
-1. **Give the product a `@base` root** inheriting a material base (`fdm_filament_pet`,
-   `fdm_filament_pla`, …) with its own `filament_vendor` and `filament_type`. No `fdm_filament_*` base
-   carries a `filament_id`, so the filament now resolves none and `generate-id` mints it on the root.
-   This is the product-root shape ([the three-part shape](filament-profiles.md#the-three-part-shape)).
-2. **Declare the tool-computed id on the preset itself.** Use the expected value `check` reports, or
-   compute it with the function below; this is not a manually chosen id. First make sure the preset
-   resolves the right `filament_vendor` and `filament_type`: with neither set, the triple resolves
-   through the generic parent and the branded product is minted under vendor `Generic`. If you need the
-   id before the file exists:
-
-   ```bash
-   python3 -c "import sys; sys.path.insert(0,'scripts'); from orca_profile_tool import generate_filament_id as g; print(g('Polymaker','PLA','PolyLite PLA'))"
-   # -> OF5CgdDq
-   ```
-
-   The quoting works unchanged in cmd and PowerShell; only swap `python3` for `py -3`.
-   `generate_preset_setting_id('<vendor folder>', '<type>', '<name>')` is the `setting_id` equivalent.
-
-A vendor's tune of a generic that keeps the `Generic X` alias is not this case: inheriting the
-generic's id is correct there, because the product really is the library generic
-([filament-profiles.md](filament-profiles.md#the-two-most-common-contributions)).
-
-## BBL's exception, precisely
-
-The exception covers **`setting_id` assignment only**, keyed on the *folder* name `BBL`:
-
-- The tool never mints or replaces a `setting_id` in `BBL/`: those are Bambu's own ids. A new
-  instantiated BBL preset with no `setting_id` therefore **cannot be fixed by the tool**, yet the
-  presence rule still applies to it: carry over Bambu's authoritative id by hand.
-- BBL is not exempt from anything else: bases still get their `setting_id` stripped, ids must still be
-  unique across the tree, and BBL `filament_id`s are minted like everyone else's, as `OF…` ids.
-
-## Ids other systems compose
-
-No id from another system is the mint of a triple, so `check` rejects one used as a `filament_id` like
-any other bad id: same error, same remedy, whoever wrote it. Three such spaces exist near the tree;
-recognise them so you do not copy one into a profile:
-
-- **Bambu's `GF…` catalog**: external and opaque, correlated to Orca's ids by the generated
-  `resources/printers/bambu_filament_ids.json`. `blacklist.json` and
-  `BBL/filament/filaments_color_codes.json` reference Bambu catalog ids by design. The rule is about
-  `filament_id` and nothing else: every BBL `setting_id` starts with `G`, and that is Bambu's own
-  preset id, not a leaked catalog id.
-- **Qidi's `QD_…`**: composed at runtime by the printer's filament box
-  (`QD_<series>_<vendor>_<typeidx>`), not a preset id.
-- **`P` + 7 hex digits, and `"null"`**: what the app gives a *user*-created filament.
-
-## Tests
-
-`python3 -m unittest discover -s scripts/tests -t scripts` (`py -3 -m …` on Windows) runs the tool's
-unit tests. Note the `-t scripts` argument; without it the imports fail. CI runs them as the first,
-non-`continue-on-error` step of the profile job; see [validation.md](validation.md#ci).

-# Printer models and variants
-
-Both live in `resources/profiles/<Vendor>/machine/`; models go in `machine_model_list`, variants and
-shared bases in `machine_list`. Every one of them is registered. A bundle may nest further subfolders
-under `machine/`, so recurse rather than globbing `machine/*.json`.
-
-## `machine_model`: a record, not a config preset
-
-The loader reads a fixed set of keys from a `machine_model` and stores only these (`version` and `url`
-are recognised and discarded):
-
-`name`, `model_id`, `nozzle_diameter`, `machine_tech`, `family`, `bed_model`, `bed_texture`,
-`hotend_model`, `default_materials`, `not_support_bed_type`, `image_bed_type`,
-`bottom_texture_end_name`, `bottom_texture_rect`, `bottom_texture_rect_longer`, `middle_texture_rect`,
-`use_double_extruder_default_texture`.
-
-**Everything else is silently dropped**, a printer config key such as `default_bed_type` or a
-misspelling included, so a neighbour carrying a key is no evidence it does anything. Printer config options belong on the `machine` preset, never here. The loader drops a model
-silently if its index entry has no name or its `nozzle_diameter` yields no sizes; `check` also requires
-the file's own `name`.

-| Field | Notes |
-| --- | --- |
-| identity | **the `name` of the `machine_model_list` entry**, which is what a variant's `printer_model` must equal. `check` forces it to equal the file's `name`, so they coincide. |
-| `model_id` | a *separate* cloud/device printer type. Optional, and not required to be unique. Not the model's identity; changing it changes device matching. |
-| `machine_tech` | only a value starting with `SL` means SLA; everything else is FFF. Write `FFF`; `FGF` behaves as FFF. |
-| `nozzle_diameter` | `;`-separated string, one token per available size. Order is free (`0.4;0.2;0.6;0.8` puts the default first). This list is the authoritative set of legal `printer_variant` values. |
-| `default_materials` | `;`-separated filament **preset names**, not `,`; case-sensitive (`@System`); order is ignored. Used to preselect filaments in the setup wizard *and* to install a printer's filaments on first run, so a dangling entry costs a real user a filament. Every name must exist (`check` fails on a name matching no filament file, here or in `default_filament_profile`), and every variant of the model needs at least one entry compatible with it (`validate_system`). |
-| `family` | a wizard grouping label only; give every model one. |
-
-### Assets
-
-`bed_model`, `bed_texture` and `hotend_model` are paths relative to the **vendor folder** (named by the
-vendor id). Convention: `<Model>_buildplate_model.stl` and `<Model>_buildplate_texture.svg`. An
-empty string is the legal "none", and is the norm for `hotend_model`.
-
-**Nothing checks that the files exist.** A missing `hotend_model` falls back to
-`resources/profiles/hotend.stl`; a missing `bed_model` makes the bed render as a generic custom bed, and a missing
-`bed_texture` renders no texture.
-Verify by hand, in exact case.
-
-Every model also has a `<Model>_cover.png` in the vendor folder; treat it as required, not optional.
-240×240 is the cap `scripts/optimize_cover_images.py` enforces. A missing cover degrades to a placeholder in both the wizard and the sidebar.
-
-## `machine`: the variant
-

-
-Minimum viable key set: `type`, `name`, `from`, `instantiation`, `setting_id`, `inherits`,
-`printer_model`, `printer_variant`, `nozzle_diameter`, `printable_area`, `printable_height`,
-`default_print_profile`. `default_filament_profile` is optional; when written it
-is an array (`["Generic PLA @System"]`), while the model's `default_materials` is a `;`-separated
-string. Unlike a `machine_model`, a `machine` **is** a config preset, so a key belonging to another
-preset type is a reported error and is removed; a misspelled key is still dropped silently.
-
-### `printer_model` and `printer_variant`
-
-1. `printer_model` is non-empty and names a model of this bundle exactly.
-2. `printer_variant` is non-empty and an exact token of that model's `;`-separated `nozzle_diameter`
-   list.
-3. For instantiated presets, when validating: split `printer_variant` on `+`; each token must start
-   with a number (a trailing non-numeric suffix such as `HF` is ignored), and the resulting **set** must
-   equal the set of `nozzle_diameter` values.
-
-Rules 1 and 2 are loader-enforced: failing either discards the whole bundle. Rule 3 only raises a
-validation error: the preset still loads, but the validator exits non-zero.
-
-`nozzle_diameter` lists one entry **per extruder**; `printer_variant` lists the **distinct** diameters
-joined with `+`: `["0.4","0.4","0.6","0.6"]` against `"0.4+0.6"` passes because the comparison is on
-sets.
-
-Write `printer_variant` as a bare diameter matching the model's list, with no unit. The conventional
-values are `0.2`, `0.25`, `0.4`, `0.5`, `0.6`, `0.8` and `1.0`; a suffixed form (`0.4HF`, `0.4HS`) or
-the `+` form is legal under rule 3. A `printer_variant` is **not** required to be unique within a
-model: an IDEX model's normal, `COPY MODE` and `MIRROR MODE` presets can all be `0.4`.
-
-The converse is **unchecked**: a nozzle size in the model's list with no matching variant is offered in
-the wizard and resolves to nothing. A variant whose `printer_model` names a sibling model by mistake
-leaves its own model's size in exactly that state.
-
-### Other keys
-
-- `default_print_profile` is a **scalar**, matched by exact preset name; not a `;` list. The named
-  process must be compatible with this printer through its resolved list or condition.
-  `validate_slice` attempts to select it and rejects generic Default fallbacks, but compatibility
-  updates can choose another compatible preset, and `check` does not resolve the name. Check the exact
-  default reference yourself.
-- `default_filament_profile` is an **array**, one name per element. Entry 0 is the filament preselected
-  when the printer is chosen; entry *i* is the preferred replacement when filament *i* is incompatible,
-  and any listed name outranks an unlisted one. The validator checks every entry. The list of a
-  printer's filaments is the model's `default_materials`: a new filament goes into `default_materials`;
-  put it first in `default_filament_profile` only if it should become the preselected one.
-- `printable_area` is an array of `"XxY"` strings: four points for a rectangle; a delta or other circular bed
-  is a polygon with one point per segment.
-- A non-BBL printer shows the plate selector only with `support_multi_bed_types` `"1"`; otherwise it
-  uses its `default_bed_type` (a plate name such as `"Textured PEI Plate"`; High Temp Plate when unset).
-  Filaments still set every plate
-  ([twelve keys](filament-profiles.md#bed-temperature-is-twelve-keys-not-one)).
-- `gcode_flavor` is usually set once in the base; the common values are `klipper`, `marlin`, `marlin2`
-  and `reprapfirmware`.
-- `printer_settings_id` does nothing in a preset file: the app replaces it with the selected preset's
-  name before slicing. Omit it, and do not copy it when cloning a bundle.
-- `min_layer_height` / `max_layer_height` are **machine** keys (one per extruder), never process keys.
-
-## Bases
-
-The conventional machine root is a base named `fdm_machine_common`, with `fdm_klipper_common` on top
-of it for Klipper printers. Which values a hardware
-family or model base holds, and when adding one pays off, is in [shared-bases.md](shared-bases.md).
-
-**There is no leading-underscore convention for bases.**
-
-## Adding a printer to an existing bundle
-
-1. Choose the names first: model, variant(s), process(es); everything else references them
-   ([naming.md](naming.md)).
-2. Add the model (`machine_model_list`) and one `machine` variant per nozzle; the minimum key sets are
-   above. Bed assets and `<Model>_cover.png` go directly in `<Vendor>/`.
-3. Add at least one process per variant naming it in `compatible_printers`
-   ([process-profiles.md](process-profiles.md#adding-a-quality-tier-or-a-nozzles-processes)).
-4. Add the variants to the filaments they should offer, and set the model's `default_materials` so every
-   variant has a compatible entry.
-5. Register everything (`update-index`), bump the version, run the id tool, validate: the
-   [authoring workflow](../SKILL.md#creating-or-modifying-a-profile).
-
-## Adding a nozzle variant
-
-1. Extend the model's `nozzle_diameter` (`"0.4"` → `"0.4;0.6"`).
-2. Add the variant preset. Either inherit the shared base (the usual choice), or the 0.4 sibling
-   (a smaller diff, but the sibling's edits now reach this file too). Follow the bundle.
-3. Override what actually changes with the nozzle: `nozzle_diameter`, `printer_variant`,
-   `default_print_profile`, `default_filament_profile`, `min_layer_height` / `max_layer_height`, and
-   retraction if the vendor tunes it.
-4. Add at least one process for the new nozzle (see [process-profiles.md](process-profiles.md)), and
-   extend the filaments' `compatible_printers` so at least one `default_materials` entry covers the new
-   variant.
-5. Register both, bump the version, run the id tool, validate.
-
-## Multi-extruder, IDEX and tool changers
-
-Per-extruder vectors hold one value per extruder (`len(nozzle_diameter)`), and a wrong length raises no
-error: a short vector acts as padded with its **first** value, not the last (`extruder_offset`
-`["0x0","50x0"]` on a 4-extruder machine reads as `0x0, 50x0, 0x0, 0x0`), and entries beyond the
-extruder count are never read.
-
-Note the two sizing families. The plain per-extruder keys (`printer_extruder_options`: `extruder_type`,
-`nozzle_diameter`, `default_nozzle_volume_type`, `extruder_printable_height`, `min_layer_height`,
-`max_layer_height`, …, given in full with the [key sets](extruder-variants.md#the-four-key-sets), plus
-`extruder_offset` and `extruder_colour`) hold one value per extruder. The variant sets
-(`retraction_length`, `z_hop`, `wipe`, `nozzle_type`, the `machine_max_*` limits at stride 2;
-[the full lists](extruder-variants.md#the-four-key-sets)) are sized to the variant length:
-`len(printer_extruder_variant)`, or one variant per extruder when the resolved preset writes no layout,
-since `extruder_variant_list` defaults to one `Direct Drive Standard` per extruder
-([widths](extruder-variants.md#widths)). `extruders_count` is a printer-tab field, not a preset key; the
-loader drops it.
-
-- Give **one entry per extruder** for ordinary per-extruder vectors such as `extruder_offset`,
-  `extruder_colour`, `min_layer_height` and `max_layer_height`. Size the variant sets to the variant
-  length × stride, one value per variant (per extruder when there is no layout; a (normal, silent)
-  pair for the `machine_max_*` limits), even where the values are the same; the loader keeps only the first value of a list-less printer's variant arrays, so declare
-  the layout when the extruders differ. A single `["0x0"]` `extruder_offset` on a dual or
-  multi-extruder machine pads every extruder to the same offset, so the offset never applies.
-- Overriding `nozzle_diameter` to a different count without restating every per-extruder vector is the
-  other half of the trap: a 4-extruder preset on a 5-extruder base inherits 5-entry vectors against 4
-  extruders.
-  The reverse is silent too: a base is stored resized to its own `printer_extruder_variant` (one variant
-  when it writes none, whatever its extruder count), so a wider variant array on it reaches the children
-  as its first value padded ([composition](extruder-variants.md#padding-truncation-and-composition)).
-  `check` does not judge the base on its own; where its extruders need different values, declare the
-  layout on the base.
-
-Structure to copy: `Custom/machine/fdm_toolchanger_common.json` + `Custom/machine/MyToolChanger 0.4
-nozzle.json` (a minimal variant on a base that gives the per-extruder vectors five entries), and
-`Ratrig/machine/RatRig V-Core 4 IDEX 300 0.4 nozzle.json` for IDEX. Take the structure from them and
-the widths from the [sizing equation](extruder-variants.md#sizing-equation). Both are list-less, so
-every variant array holds one value per extruder and the loader keeps only the first: fine while every
-extruder shares the same retraction and limits. Add the extruder-variant layout
-(`extruder_variant_list`, `printer_extruder_variant` / `printer_extruder_id`,
-`default_nozzle_volume_type`) when the hardware has swappable nozzle volume types or mixed extruder
-types, or as soon as one extruder needs its own value in a variant key; how to author it, and the
-matching process and filament variants, is in [extruder-variants.md](extruder-variants.md).
-(`nozzle_volume_type` itself is not a machine-preset key.)
-
-## Custom G-code
-
-The keys are `machine_start_gcode`, `machine_end_gcode`, `change_filament_gcode`,
-`machine_pause_gcode`, `before_layer_change_gcode` and `layer_change_gcode`. Each is one string with
-embedded `\n`. Never split G-code into a JSON array of lines: the loader joins array elements with `,`
-into a single line (a one-element array is equivalent to the string): a two-element
-`machine_start_gcode` becomes one line, `PRINT_START …,SET_PRESSURE_ADVANCE ADVANCE=0.046`.
-Conditionals are `{if …}` / `{elsif …}` / `{else}` / `{endif}`.
-
-Placeholder errors only surface when the G-code is actually expanded, which means `validate_slice`:
-
-```bash
-./scripts/check_profile.sh --vendor "<Vendor>" validate_slice
-# Windows:  scripts\check_profile.bat -Vendor "<Vendor>" validate_slice
-```
-
-What the sweep covers is in [validation.md](validation.md#validate_slice); a printer whose output has no
-`CP TOOLCHANGE START` fails it, because its `change_filament_gcode` never expanded.

-# Preset naming
-
-A preset's `name` is its identity, not decoration. The index registers it; `inherits`,
-`compatible_printers`, `printer_model` and the `default_*` keys reference it by the exact,
-case-sensitive string; `renamed_from` migrates it; `setting_id` and `filament_id` hash it
-([ids.md](ids.md)). Treat a name change as an identity change that needs
-[migration](vendor-bundle.md#renamed_from), not a relabel. Which part of each name the loader acts on
-is the table in [SKILL.md](../SKILL.md#names); this page holds the conventions.
-
-## `machine_model`
-
-`<Model>`, vendor-prefixed: `Bambu Lab X1 Carbon`, `Creality K1`, `Prusa CORE One`. Each variant's
-`printer_model` names it verbatim (a mismatch discards the bundle), and its index entry equals the
-file's `name`. It is also the stem of `<Model>_cover.png` and, by convention, of the bed assets
-(`<Model>_buildplate_model.stl`).
-
-## `machine` (variant)
-
-`<Model> <nozzle> nozzle` is near-universal (`Bambu Lab X1 Carbon 0.4 nozzle`). Casing varies
-(`nozzle` / `Nozzle`): match the bundle, not this page. A variant that is not nozzle-specific (a
-special toolhead, a multi-material build, IDEX copy and mirror modes such as
-`<Model> COPY MODE (0.4 nozzle)`) may drop or reshape the suffix; it is still an exact reference. `printer_variant`
-holds the nozzle token: `0.4`, a suffixed `0.4HF`, or `0.4+0.6` for mixed nozzles
-([rules](machine-profiles.md#printer_model-and-printer_variant)).
-
-## `process`
-
-`<layer height>mm <quality> @<target>`. The quality word stays before `@` and the printer target after
-it: a printer model in the quality position leaves the tier undescribed. The `@<target>` is a label,
-and need not equal any variant name; compatibility comes from `compatible_printers` or the
-condition. The quality ladder and per-nozzle labels are in
-[process-profiles.md](process-profiles.md#naming).
-
-## `filament`
-
-`<Product> @<target>`. The product half, up to the first `@` and right-trimmed, is the **alias**:
-shadowing matches on it and `filament_id` hashes it. The target half is a label, except for the
-reserved forms:
-
-- `@base`: a non-instantiated product root. Convention only; a base is really
-  `instantiation: "false"` without `setting_id`
-  ([the three-part shape](filament-profiles.md#the-three-part-shape)).
-- `@System`: the OrcaFilamentLibrary selectable shim, and the convention for an all-printer product
-  (`<Product> @System`, empty `compatible_printers`). Not enforced, so a deviation is worth a review
-  comment. The literal `Generic <mat> @System` is also load-bearing for project recovery
-  ([alias shadowing](filament-profiles.md#alias-shadowing)).
-- Printer tunes. BBL's shape is the reference: `@<Vendor>` (vendor-wide), `@<Vendor> <Model>` (one
-  model), `@<Vendor> <Model> <nozzle> nozzle` (one variant). Other vendors differ: a bare model
-  (`QIDI ABS-GF@Q2-Series`), a printer serial, Creality's `@<Model>-all`. Judge specificity from
-  `compatible_printers`, never from the name
-  ([one variant, one profile](filament-profiles.md#overlapping-coverage-one-variant-one-profile-per-product)).
-- No colour in the product name: `<Product> <Colour>` presets are not authored; colour is chosen at
-  runtime ([colour](filament-profiles.md#colour-is-a-runtime-property)).
-
-## Bases
-
-| Type | Base names |
-| --- | --- |
-| `machine` | `fdm_machine_common`, `fdm_<vendor>_common`, `fdm_klipper_common`, or an established machine-family base |
-| `process` | `fdm_process_*`: shared roots and per-layer-height or per-nozzle bases such as `fdm_process_single_0.20` or `fdm_process_<vendor>_<lh>_nozzle_<n>` |
-| `filament` | `fdm_filament_*` material roots, `<Product> @base` product roots |
-
-There is no leading-underscore convention. Base names repeat across bundles by design:
-every bundle may have its own `fdm_process_common`, and a product root such as `Fiberon PA6-CF @base`
-can exist in both the library and a vendor. Investigate a newly authored base that kept an unrelated
-selectable preset's name from a copy.
-
-## Uniqueness
-
-- Type + name is unique within a bundle, indexed or not; `check` enforces it.
-- `machine_model` names are unique across the whole tree; `check` enforces it even with `--vendor`.
-  Printer-type lookup matches `printer_model` against every vendor's models and takes the first, so a
-  duplicate makes it depend on vendor order.
-- At load, two selectable presets with one name discard the bundle, and a duplicate across vendors
-  is a validator error. Two bases with one name, or a base and a selectable preset, load silently and
-  the first in the index wins; an unindexed twin is therefore one `sub_path` edit away from becoming
-  the parent every child resolves to.
-
-## Filenames and paths
-
-The loader keys off `name`, and a filename that disagrees usually still loads, but keep the filename
-equal to the `name` and to the index `sub_path`. Match the exact case of every `sub_path` and asset
-filename: Linux filesystems distinguish case even when a macOS or Windows checkout does not, and
-preset-name references are case-sensitive on every platform. Avoid Windows-invalid characters
-(`< > : " | ? *`), reserved device names such as `CON` and `NUL` (with any extension), and trailing
-spaces or dots in a path component; a space right before `.json` is not a trailing space.
-
-## Checking names
-
-Check the `name` of every newly added profile, and every intentional rename, against its type and role
-(model, selectable preset or base). `check` does not enforce the shapes on this page: inspect the
-added or renamed presets in the diff, use neighbouring names as context, and follow the bundle's
-established style where the conventions allow variation. Preserve shipped names during ordinary
-tuning; renaming a shipped selectable preset needs `renamed_from`.

-# Process profiles
-
-Processes live in `resources/profiles/<Vendor>/process/`, selectable leaves and shared bases alike, and
-every one of them is registered in `process_list`. There are no global processes shared across vendors.
-
-## Naming
-
-`"<layer height>mm <quality> @<target>"` is near-universal, so match it: the quality word before `@`,
-the printer label after it ([naming.md](naming.md#process)).
-
-Follow the bundle's existing quality vocabulary. BBL's common ladder relates the quality word to the
-layer height / nozzle ratio; it is a naming convention, not a loader constraint:
-
-| Quality | Ratio | 0.2 nozzle | 0.4 | 0.6 | 0.8 |
-| --- | --- | --- | --- | --- | --- |
-| Extra Fine | 0.2× | — | 0.08 | — | — |
-| Fine | 0.3× | 0.06 | 0.12 | 0.18 | 0.24 |
-| Optimal | 0.4× | 0.08 | 0.16 | 0.24 | 0.32 |
-| Standard | 0.5× | 0.10 | 0.20 | 0.30 | 0.40 |

-| Extra Draft | 0.7× | 0.14 | 0.28 | 0.42 | 0.56 |
-
-This is the `fdm_process_single_<lh>_nozzle_<n>` ladder; 0.4 is commonly the unsuffixed nozzle default.
-Newer BBL printers add High Quality, Balanced Quality and Strength tiers. Match neighbouring names rather
-than renaming shipped tiers to fit the table. On a model with several nozzles, processes for the other
-nozzles usually carry the nozzle in the label (`0.30mm Standard @BBL X1C 0.6 nozzle`); follow the bundle.
-
-The `@target` is a human label, not a reference: it need not equal any printer variant name.
-Compatibility comes from the resolved list or condition, not this label.
-
-## Shape
-
-A selectable leaf has `type`, `setting_id`, `name` and `instantiation`, normally `inherits` and
-`from`, plus compatibility; its slicing keys, `layer_height` included, normally come from its bases. A
-base has `type`, `name`, `instantiation`, `from`, and **no** `setting_id`.
-
-**Target shape: a 7-key leaf.** `OrcaArena` is the cleanest model:
-`fdm_process_common` → `fdm_process_arena_common` → `fdm_process_arena_<lh>_nozzle_<n>` → leaf, where the
-leaf carries only `type`, `name`, `inherits`, `from`, `setting_id`, `instantiation` and
-`compatible_printers`, and the per-nozzle base holds the layer height and all eight line widths.
-[shared-bases.md](shared-bases.md#levels) says which level each process setting belongs to.
-
-BBL's *layering* is a model too (every leaf inherits a base, names its printers directly and holds no
-layer height of its own), but not its content: its leaves carry multi-variant `print_extruder_variant`
-arrays that no single-variant vendor needs ([extruder-variants.md](extruder-variants.md#process)).
-
-A bundle has its own `fdm_process_common` as the inherits-less root, since a process inherits only
-inside its bundle; starting a new bundle's from another vendor's copy is fine.
-
-Beware leaf-inherits-leaf: a bundle may chain selectable processes several levels deep, so editing one
-silently changes others. Check a leaf's children before editing it.
-
-## Compatibility
-
-A leaf sets `compatible_printers` directly, inherits it from a base, or falls through to
-`compatible_printers_condition`. After resolving `inherits`, **every selectable process has one or the
-other**: that is the invariant to review against. Unlike filaments, inheriting `compatible_printers` is
-legitimate for a process, and no check enforces its presence.
-
-- A non-empty `compatible_printers` makes `compatible_printers_condition` **dead**. Use one or the
-  other.
-- A condition that fails to parse means *compatible with everything*: a warning, not an error. A typo
-  widens compatibility instead of narrowing it.
-- A regex in a condition must match the **whole** string, so wrap the keyword in `.*`; `.` also spans
-  the newlines inside `printer_notes`.
-- A `printer_notes` keyword that prefixes another model's keyword matches both. Guard it with a
-  character class after the keyword, and combine terms with `and`:
-
-  ```
-  printer_notes=~/.*PRINTER_MODEL_COREONE[^_a-zA-Z0-9].*/ and nozzle_diameter[0]==0.4 and printer_notes=~/.*HF_NOZZLE.*/
-  ```
-
-  The `[^_a-zA-Z0-9]` exists because `PRINTER_MODEL_COREONE_L` also contains `PRINTER_MODEL_COREONE`.
-
-A leaf listing a whole model family is where a newly added printer is usually forgotten.
-
-## Values to review per nozzle
-
-| Key group | Review |
-| --- | --- |
-| `line_width` and per-region widths | resolved widths suit the nozzle and layer height |
-| `layer_height`, `initial_layer_print_height` | within the printer's `min_layer_height` / `max_layer_height` |
-| print speeds | consistent with flow limits and hardware tuning |
-| shell layers, wall loops, accelerations, support Z distances | preserve the intended thickness, motion and support behaviour |
-
-**A common starting pattern is line width = nozzle + 0.02 mm**: 0.22 / 0.42 / 0.62 / 0.82 / 1.02. In
-that pattern, at 0.4, `inner_wall_line_width`, `sparse_infill_line_width`, `skin_infill_line_width` and
-`skeleton_infill_line_width` widen to 0.45 and `initial_layer_line_width` to 0.5; at 0.2,
-`initial_layer_line_width` widens to 0.25. Also derived, and easily missed:
-`ironing_inset = line_width / 2` (0.11 / 0.21 / 0.31 / 0.41). These are examples, not required values;
-preserve intentional vendor tuning and percentage or automatic widths, and validate their resolved
-values.
-
-`min_layer_height` and `max_layer_height` are machine keys; no process file sets them.
-
-### Slicing limits
-
-Slicing rejects a process that breaks one of these (the message in italics):
-
-1. `initial_layer_print_height` ≤ the smallest `nozzle_diameter` (with a raft, the nozzle of the raft's
-   first-layer extruder).
-2. `layer_height` ≤ the smallest `nozzle_diameter`: *"Layer height cannot exceed nozzle diameter."*
-3. `line_width` and the seven per-region widths (inner and outer wall, sparse infill, internal solid
-   infill, top surface, skin, skeleton) > `layer_height`: *"Line width too small"*.
-   `support_line_width` is checked only when the object has support or a raft;
-   `initial_layer_line_width` is never checked. A width that resolves to 0 (automatic) is skipped.
-4. Every width ≤ 5 × the largest `nozzle_diameter`: *"Line width too large"*.
-
-Two further rules cover `bridge_line_width`: it must not exceed the nozzle diameter, and must exceed
-`layer_height` unless `thick_bridges` and `thick_internal_bridges` are both on. The slice sweep starts
-from printer defaults rather than enumerating every process: **a new non-default process gets no
-dedicated slice coverage in CI.**
-
-## What CI checks on a process
-
-Structure, not content: `process_list` name consistency **and** index coverage the other way, two files
-claiming one process name, the `extruder_clearance_radius` / `extruder_clearance_max_radius` conflict
-pair, duplicate JSON keys, a file `normalize` would rewrite, the five `setting_id` rules (present on
-selectable presets, absent from bases, equal to the formula outside `BBL/`, unique across the tree, and
-no misspelled key `settings_id`), and the variant arrays: every array of `print_options_with_variant`
-exactly `variant length × stride` wide in each selectable process that writes it, and a written
-`print_extruder_id` one entry per variant
-([variant arrays](validation.md#variant-arrays)). `compatible_printers` presence is checked for
-**filaments only**.
-
-The loader derives a missing `setting_id` on the fly, so the validator accepts a process without one;
-only `orca_profile_tool.py check` catches it.
-Running the validator alone gives a false all-clear.
-
-## Silent failures specific to processes
-
-- **Unknown or misspelled keys are discarded with no error and no warning**, both plain typos
-  (`inital_layer_height`, `tree_support_bramch_diameter_angle`, `sparse_infill_patter`) and keys
-  copied from other slicers that Orca never defined.
-- Keys on the tool's obsolete list (`adaptive_layer_height`, `overhang_totally_speed`, …) are rejected
-  by `check`'s normalization pass across preset types; `normalize` removes them. The additional per-key
-  obsolete warnings read `filament/` only.
-- A dangling `compatible_printers` inside an `instantiation: "false"` base is reported only through a
-  selectable child that inherits it unchanged; it goes unreported when every child overrides the list,
-  or when the base has no instantiated children.
-- Nothing flags an orphan base that nothing inherits, usually the leftover of a half-finished nozzle
-  addition.
-
-## Adding a quality tier or a nozzle's processes
-
-1. Choose the layer height and quality label using the bundle's existing ladder.
-2. If the bundle has per-nozzle bases, add one (`fdm_process_<vendor>_<lh>_nozzle_<n>`) with the layer
-   height, nozzle-appropriate line widths, `initial_layer_print_height` and `ironing_inset`.
-3. Add the leaf: 7 keys, `compatible_printers` naming the exact printer variant(s).
-4. Register both in `process_list`, parent first, bump the version, run the id tool and validate: the
-   [authoring workflow](../SKILL.md#creating-or-modifying-a-profile).
-5. Slice this process explicitly with its intended printer
-   ([on a copy of the tree](validation.md#checking-a-copy-of-the-tree)); the sweep gives non-default
-   tiers no dedicated coverage. If it is a printer's `default_print_profile`, verify the exact name and
-   resolved compatibility too: the sweep may fall back or select another compatible process.

-| Not checked by CI | Consequence |
-| --- | --- |
-| The `version` bump | The change never reaches an upgrading user; an absent `version` hides the vendor from the setup wizard |
-| A misspelled setting key | The setting silently has no effect |
-| A filename Windows cannot check out, or one that differs from its `sub_path` only in case | Works on the author's machine, breaks the bundle on another platform |
-| `bed_model` / `bed_texture` / `hotend_model` / cover pointing at a missing asset | A missing bed model renders a generic custom bed and a missing texture renders none, the hotend falls back to the generic model, the cover shows a placeholder |
-| A nozzle size in a model's list with no matching variant | The size is offered and resolves to nothing |
-| A non-default process | `validate_slice` gives non-default quality tiers no dedicated coverage |
-| Whether the intended default survived compatibility selection | The sweep can select a different compatible preset |
-| A dangling `compatible_printers` inside a base whose children all override it (or that has no instantiated children) | The reference check walks resolved selectable presets, so it reports a base's list only through a child that inherits it unchanged (a bad `inherits` in a base *is* caught) |
-| A base nothing inherits | Dead weight, usually the leftover of an unfinished nozzle addition |
-| A `renamed_from` whose old name is still a live preset | The redirect is inert while a live preset carries that name |
-| A preset differentiated only by colour, or an all-printer library preset without `@System` | Per-colour presets split one product across several ids and the selector fills with near-duplicates; CI stays green |
-| Plate temperatures for plates the printer has | The user's plate reads an unset or inherited temperature |
-| Per-extruder vector length on a multi-extruder printer | Silently padded (with the **first** value) or truncated |
-| A new variant appended instead of inserted at its variant index, a variant array widened on a base with a shorter list, or a variant a filament/process lacks | Values shift onto the wrong extruder, are cut before any child inherits them, or resolve to the first variant: High Flow silently gets Standard values |
-| A name that ignores its type's convention: a printer model in a `process` quality position, or an unrelated target label or base name left in a copied preset | The selector misrepresents the preset's quality or intended printer |
-| Values: temperatures, speeds, widths, pressure advance | A wrong value prints wrong while CI stays green |
-
-## 1. Was the vendor `version` bumped?
-
-For **every** bundle whose folder the diff touches, `resources/profiles/<Vendor>.json` must have its
-`version` incremented: last component, carrying `.99` into the third component. A library change means
-bumping `OrcaFilamentLibrary.json`.
-
-*Why:* nothing in CI checks it, and the app reinstalls a bundled profile set only when its version is
-newer than the installed one: without a bump the change reaches neither an upgrading user nor the
-author's own running app. Without any `version` the vendor vanishes from the setup wizard, and neither
-`check` nor the validator reports it.
-
-## 2. Was the index rebuilt, and does the diff contain only this change?
-
-`check` fails on an unregistered file, on an index `update-index` would reorder, and on a file
-`normalize` would rewrite, so a PR that skipped them arrives red and you do not have to spot the
-omission yourself. Three things are still yours:
-
-- **The index diff belongs to this change.** `update-index` rewrites whole `*_list` sections. If the
-  bundle had drifted, the author's PR now carries someone else's reordering; ask for it in a separate
-  commit rather than reviewing it inline.
-- **A deleted selectable preset needs a successor** as in item 4. `update-index` removes its
-  registration; `validate_custom` detects the break only for names covered by released fixtures.
-- **`normalize` edits content, not just layout.** It drops `version` and `is_custom_defined` from preset
-  files, removes obsolete keys, deletes six print-speed keys from filament profiles, and resolves
-  `extruder_clearance_radius` against `extruder_clearance_max_radius` by keeping the larger
-  ([what normalize changes](validation.md#normalize-and-update-index-are-part-of-the-check)). Check that
-  the keys it removed were meant to go.
-
-Index order is dependency order, not alphabetical: parents and include templates before the presets
-that use them, then, in name order, the entries that neither depend on nor are depended on by another
-entry of their own list (such as a leaf filament whose only parent is in the library), and any entry on
-a dependency cycle. Judge a hand-placed entry only by
-`update-index --dry-run`: if it reports nothing to rebuild, the position is not a finding.
-
-*Why:* the index is the loader's only entry point. Out-of-order entries fail with `can not find inherits`
-and take the whole vendor bundle down; an unindexed file gets reviewed, merged and never loads.
-
-## 3. Are ids generated, not written?
-
-No hand-typed or copied `setting_id` / `filament_id`. Instantiated presets have a `setting_id`; bases do
-not. `check` enforces all of that; what it cannot tell you is whether the identity *should* have moved.
-
-A rewritten or removed `filament_id` means a product's identity moved (a renamed alias, or an edited
-`filament_vendor` / `filament_type`), and the old id is not forwarded anywhere. Confirm that was
-intended, and that a new id is not a rename in disguise.
-
-*Why:* a duplicate `filament_id` on one printer makes AMS spool matching a coin toss; a copied
-`setting_id` breaks preset identity. See [ids.md](ids.md).
-
-## 4. Does anything disappear for existing users?
-
-A rename, a deletion, or a flip of `"instantiation": "true"` → `"false"` on a shipped selectable preset
-removes the name from the preset collection. It needs `renamed_from` on a selectable successor
-([renamed_from](vendor-bundle.md#renamed_from)), and only one preset may claim a given old name. The
-claimed old name must **not** still be a live preset; the redirect is inert if it is.
-
-*Why:* user presets inheriting it die with `can not find parent <name> for config <file>!`; 3MF-embedded
-presets are dropped with no error at all. Commit `33923464ae` reverted exactly this for Cubicon;
-`6943b6ddc3` redid it correctly with `renamed_from`. CI's `validate_custom` catches the shipped-name
-case, but not an inert `renamed_from`.
-
-## 5. Is `compatible_printers` right?
-
-Exact printer **variant** names, non-empty on every instantiated filament outside OrcaFilamentLibrary,
-and written in the preset's own file ([SKILL.md rule 9](../SKILL.md#rules); the resolved-vs-own-key trap
-is in [filament-profiles.md](filament-profiles.md#compatible_printers)). A `machine_model` name instead
-of a variant name is the usual mistake: `check` passes it, the validator reports
-`references unknown compatible_printers`. Watch for a nozzle-specific tune that inherited or copied the
-base's full printer list, and for two presets of one product with overlapping lists: duplicate combobox
-entries and an ambiguous AMS match.
-
-Two presets of one product (`filament_id`) must not share a variant. Resolve it by specificity: move the
-variant to the most specific preset and remove it from the more general ones, which is preferred over
-deleting a profile. Then repoint the machine's `default_filament_profile` and the model's
-`default_materials` at the profile that now covers it. See
-[one variant, one profile](filament-profiles.md#overlapping-coverage-one-variant-one-profile-per-product).
-
-*Why:* real shipped bugs twice (`b7b3418baf` filaments "showing up everywhere", `ff83aa41ef` duplicate
-Flashforge entries). The Python `check` passes on an overlap; only the full `check_profile.sh`
-(`validate_system`) reports `Ambiguous AMS filament match`.
-
-## 6. One product, one all-printer preset; colour is not a preset
-
-No presets that differ only by colour: `filament_id` identifies a product, and the colour comes from the
-spool at runtime. An all-printer library product is a `<Product> @System` shim with an empty
-`compatible_printers` ([colour](filament-profiles.md#colour-is-a-runtime-property)).
-
-*Why:* per-colour presets pass every check, so this is a review call.
-
-## 7. Model ↔ variant ↔ process consistency
-
-- A new nozzle size → the model's `nozzle_diameter` list extended, a variant with a matching
-  `printer_variant`, and at least one process listing that variant. Every size in the model's list has a
-  variant (unchecked).
-- `default_print_profile` is one exact name (not a `;` list), and that process's resolved compatibility
-  list or condition includes this printer.
-- `default_filament_profile` is an array of names that exist.
-- Each variant of the model has at least one compatible entry in the model's `default_materials`.
-
-*Why:* an unlisted `printer_variant` is a hard bundle-load failure. Default process selection is weaker:
-the sweep attempts the named default, then updates compatibility and rejects generic Default fallbacks,
-so another compatible process can conceal a bad reference. Inspect it even after a pass.
-
-## 8. Types and spellings
-
-Every value a string or an array of strings; `filament_type` an array; `instantiation` the string
-`"true"` / `"false"`; custom G-code one string, never an array of lines ([SKILL.md rule 5](../SKILL.md#rules)).
-Check index metadata and model `nozzle_diameter` especially: wrong types there can abort loading for
-**every** vendor.
-
-The part only a reviewer can do: check new setting keys against `src/libslic3r/PrintConfig.cpp`. A
-misspelled key is silently discarded ([rule 6](../SKILL.md#rules)), the single most common way a profile
-edit does nothing while CI stays green.
-
-## 9. Blast radius of a base edit
-
-A change to `fdm_*_common.json` or any other base reaches every child at once. Ask which presets it
-touches: several reverts in this repo are exactly this (`41d1b0d3c8`, `dc491166a8`). Also check whether
-the edited leaf has children of its own: a bundle may chain leaf-inherits-leaf several levels deep. A
-newly added base that nothing inherits is dead weight, and a dangling
-`compatible_printers` inside a base is reported only through a child that inherits it unchanged. A diff
-that only moves values between presets and bases must leave every selectable preset loading what it
-loaded: ask for the `compare` result ([shared bases](shared-bases.md#nothing-loads-differently)), and
-check each new base against the [balance rules](shared-bases.md#balance).
-
-## 10. Do the numbers make sense for the nozzle and material?
-
-Check resolved widths and layer heights against the nozzle, temperatures against the material (PLA
-values under an ASA name print wrong), and flow limits / pressure advance against the actual hardware
-and material. The patterns in [process-profiles.md](process-profiles.md#values-to-review-per-nozzle)
-are examples, not mandatory values; [filament-profiles.md](filament-profiles.md#tuning-per-nozzle-and-per-variant)
-explains what to revisit for a nozzle change. A cloned preset's unchanged volumetric speed needs
-particular scrutiny.
-
-Settings tuned for real hardware cannot be verified by reading the diff. Say so rather than approving
-numbers nobody measured.
-
-## 11. Plate temperatures
-
-A filament sets the plate temperature for every plate the printer plausibly has, as its siblings do;
-`textured_cool_plate_temp` is the one most often forgotten
-([twelve keys](filament-profiles.md#bed-temperature-is-twelve-keys-not-one)).
-
-## 12. Asset references (not checked anywhere)
-
-`bed_model`, `bed_texture`, `hotend_model` and `<Model>_cover.png` exist under
-`resources/profiles/<vendor folder>/`, in exact case. Nothing checks them.
-
-## 13. `default_materials` and `default_filament_profile` (checked by CI)
-
-`check` fails on a `default_materials` / `default_filament_profile` name that matches no filament file,
-and `validate_system` on a variant with no compatible system filament in `default_materials`, so a
-dangling entry no longer reaches review. When compatibility moves between profiles of a product, the
-machine's `default_filament_profile` and the model's `default_materials` must be repointed at the most
-specific profile that still covers the variant, dropping generic entries that no longer apply; the same
-[specificity rule](filament-profiles.md#overlapping-coverage-one-variant-one-profile-per-product) applies
-when adding or fixing defaults. Scope the run while working on one vendor:
-
-```bash
-python3 scripts/orca_profile_tool.py check --vendor "<Vendor>"   # py -3 on Windows
-```
-
-## 14. Per-extruder vectors (not checked) and variant arrays (widths and layout checked)
-
-One entry per extruder for the plain per-extruder vectors; the variant sets are sized to the variant
-length, `len(printer_extruder_variant)` or one per extruder when the resolved preset has no layout (a
-per-extruder difference in those keys still needs the layout, since the loader keeps only the
-first value of a list-less printer's arrays). A wrong length is silently padded, repeating the **first**
-value, not the last, or truncated. The two sizing families and the worked cases are in
-[machine-profiles.md](machine-profiles.md#multi-extruder-idex-and-tool-changers).
-
-`check` reports a variant array of any type that is not exactly the `variant length × stride` width
-of the selectable preset that writes it, one value included, as an error whatever the values;
-`check --strict` also reports one that reaches a selectable preset at another width. A base is not
-judged on its own. On a machine it
-also reports layout keys that disagree: `printer_extruder_variant` / `printer_extruder_id` not the
-flattening of `extruder_variant_list`, a variant without its extruder's `extruder_type` prefix, a
-`default_nozzle_volume_type` the extruder does not list, a list of several variants without the pair, a
-pair without the list that puts several variants on one extruder. On a machine or a process, an id
-array, written or inherited, whose length differs from its variant list is an error; the id and
-layout rules judge the composed preset without `--strict`. Two layout findings are warnings: a
-pair without the list that `single_extruder_multi_material` off would replace at load, and a process
-without `print_extruder_id` whose variants repeat. The full rules are in
-[variant arrays](validation.md#variant-arrays). `check_variant_names` separately holds every variant
-string, `extruder_type`, `nozzle_volume_type` and `default_nozzle_volume_type` to the engine's enums
-in every bundle, BBL included, failing on a dead variant, a legacy spelling and a variant list that
-names one variant twice ([variant names](validation.md#variant-names)).
-
-On a multi-variant printer, still check by hand:
-
-- that a new variant's values sit at its variant index (machine limits as a (normal, silent) pair at
-  `2 × index`) in every file of the chain that restates the key, `include` templates included;
-- that each process lists every (extruder id, variant) pair its printers can select;
-- that no array was widened on a base with a shorter variant list: the loader cuts it before the
-  children inherit it ([composition](extruder-variants.md#padding-truncation-and-composition)), and
-  `check`, even `--strict`, composes without that cut, so it passes;
-- that only keys in [the four sets](extruder-variants.md#the-four-key-sets) carry per-variant values;
-- that the High Flow variants carry measured values rather than copies
-  ([checking and testing](extruder-variants.md#checking-and-testing)).
-
-## 15. Non-default processes get no slice coverage
-
-`validate_slice` starts from printer defaults; it does not enumerate every process. Slice a new or
-changed non-default tier explicitly with its intended printer
-([on a copy of the tree](validation.md#checking-a-copy-of-the-tree)).
-
-## 16. Do the preset names follow the conventions?
-
-Check **every newly added profile and intentional name change**, including models and bases, against
-[the naming conventions](naming.md#checking-names): no printer model in a process quality position, no
-target label or base name left over from a copied preset, the bundle's established style. Preserve
-shipped names during ordinary tuning; renaming a shipped selectable preset requires the migration in
-item 4.
-
-*Why:* CI checks name uniqueness, but does not enforce the naming conventions. Catch naming mistakes
-before the names ship and existing projects depend on them.
-
-## 17. Cross-platform filenames and paths (not checked)
-
-Check for Windows-invalid characters, reserved device names, trailing path-component spaces or dots,
-and case mismatches between `sub_path` or asset references and the files on disk. See
-[filenames and paths](naming.md#filenames-and-paths).
-
-## 18. Housekeeping worth a nit, not a block
-
-`"from"` other than `"system"` (the bundle loader ignores it, though loading the file as a CLI config
-rejects anything but `system` / `user` / `User`), `printer_settings_id` copied from another vendor,
-redundant overrides that restate the parent's value, siblings that each repeat a value their base could
-hold ([shared bases](shared-bases.md)), and a filename that disagrees with the preset's
-`name` (the loader keys off `name`).
-
----
-
-## Reporting the review
-
-A finding is **one defect**: its file (or quoted lines), what breaks at runtime or in CI, and the fix.
-Split independent defects into separate findings even when they live in one file: five id problems in
-one bullet get one fix and four survivors. Say which findings `check` or the validator reports and which
-only a reader catches: a missing version bump, a misspelled key and wrong temperatures pass CI, so a
-contributor who only reruns the tools fixes what CI flags and resubmits the rest.
-
-Severity discriminates only if it is earned:
-
-| Severity | Means |
-| --- | --- |
-| blocker | the bundle fails to load, or a preset is unreachable at runtime |
-| major | CI fails, existing users lose a preset, or a value prints wrong while CI stays green (PLA temperatures under an ASA name; a misspelled key whose intended value differs from the inherited one) |
-| minor | wrong but working: redundant or dead keys that change nothing, `from`, naming |
-
-Compute every number and id (`orca_profile_tool.py`, a scripted count) or omit it: one invented count
-makes a reader stop trusting the right ones. Report a command's result only if you ran it. End with a
-verdict: can it merge as it stands?

-# Shared bases
-
-Use this when drafting several presets at once, after `fix-variant`, or when sibling presets repeat the
-same values. Each value is written once, on the base of the group it is true for, and a selectable
-preset holds its identity and what makes it different. The work has two halves: choosing the groups,
-which is judgment, and moving the values, which must leave every preset loading exactly what it loaded
-before.
-
-## When
-
-- **Drafting** a printer family, a quality ladder or a product line: place each setting at its
-  [level](#levels) before writing any preset, then write the presets as overrides
-  ([Rule 7](../SKILL.md#rules)).
-- **After `fix-variant`.** It resizes each array in the selectable preset that writes it and never
-  moves or deletes a value ([variant arrays](validation.md#variant-arrays)). A family whose presets all
-  wrote one value now repeats the widened array in every preset, and a preset that restated what it
-  inherits now restates it wider.
-- **Converting full copies**: a machine that inherits nothing, or a filament that restates fifty-plus
-  keys, is the style to move away from ([filament style](filament-profiles.md#style)).
-
-Out of scope:
-
-- **BBL.** Its profiles are synced from BambuStudio: a restructure is overwritten by the next sync and
-  makes every later sync diff unreadable. Fix BBL values in the file that holds them.
-- **OrcaFilamentLibrary bases for one vendor's values.** A library base reaches every bundle's
-  filaments. Put a vendor's shared values on a base in its own bundle (a product `@base`, or a vendor
-  base that inherits the library's), and change a library base only for a value true of every filament
-  below it in every bundle.
-- **Families the change does not touch.** Restructure the presets you are already changing; a
-  bundle-wide pass is a change of its own. Commit a restructure without any value change, so `compare`
-  alone verifies it.
-
-## Nothing loads differently
-
-A restructure changes where values are written, never what a selectable preset loads. Presets keep
-their `name` and `setting_id`, and user presets and projects refer to a system preset by name and store
-their own changes against what it loads, so an unchanged load changes nothing for users. Prove it with
-the bundled helper, from the repository root (every subcommand takes `--profiles <dir>` to work on a
-copy of the tree):
-
-```bash
-python3 .claude/skills/orca-profiles/scripts/shared_settings.py snapshot <before.json>   # before any edit
-python3 .claude/skills/orca-profiles/scripts/shared_settings.py compare <before.json>    # after: "0 difference(s)", exit 0
-```
-
-`snapshot` records every selectable preset of every bundle as the loader stores it: the parent's stored
-config, each `include` at the width its file wrote, the preset's own keys, then every variant array
-resized to the preset's own variant list ([composition](vendor-bundle.md#inherits-and-include)). It
-models the step `check` does not see: a base is stored after its own resize, so an array wider than a
-base's list reaches its children cut. It also leaves out what the loader reads from each file and never
-hands down (`name`, `type`, `from`, `instantiation`, `inherits`, `include`, `setting_id`,
-`renamed_from`, `description`, `version`, `url`, `is_custom_defined`), so those keys never move to a
-base. Nor does it record `print_settings_id`, `printer_settings_id` or `filament_settings_id`: the app
-replaces them with the selected presets' names before slicing, so a file's value never counts. Delete
-them from the presets you restructure rather than moving them to a base.
-
-It does not know the built-in defaults, so `compare` lists a key written on one side only (no file of
-the preset's chain writes it on the other) apart from the differences, and exits 1 for either. A
-difference is a value the edit changed: undo it, or make it a separate, deliberate change. A one-sided
-key is no change only when its written value is the option's default in `PrintConfig.cpp`: confirm
-each, as when a preset that loaded the default by leaving a key out must now write it
-([Balance 5](#balance)). A value equal to the default needs writing nowhere when no base above writes
-another: delete it from the presets rather than moving it, and confirm the one-sided keys.
-
-## Levels
-
-A base stands for a level of the vendor's catalogue, and a setting lives at the level that determines
-it. The test for a shared value: if it had to change for one preset of the group, should it change for
-all of them? If yes, it is the group's and goes on the group's base. A value that is only equal today
-(two unrelated printers with the same acceleration) stays in each preset: a base built on coincidence
-is later edited for one preset and silently changes the others. For a default with exceptions
-([Balance 5](#balance)), ask the question of the presets that inherit the default.
-
-The tables give each setting's usual level; the test decides for a given bundle: where each toolhead
-(Bowden or Direct Drive) has its own default filament, `default_filament_profile` follows the
-toolhead, not the nozzle. Levels run
-coarse to fine, and a chain need not visit every level: each preset or base inherits the next coarser
-level that has a base.
-
-| Machine level | Base | Settings it determines |
-| --- | --- | --- |
-| Vendor | `fdm_machine_common`, `fdm_<vendor>_common` | the vendor's defaults for every printer |
-| Firmware | `fdm_klipper_common`, `fdm_marlin_common` | `gcode_flavor`, G-code that calls the firmware's macros (layer change, pause, filament change), `host_type`, `print_host`, the thumbnail format |
-| Hardware family: models that share a frame, motion system, toolhead or extruder layout | `fdm_<vendor>_<family>_common` (`fdm_qidi_x3_common`, `fdm_machine_eryone_ER20_common`) | the `machine_max_*` limits, `extruder_clearance_*`, the toolhead's retraction where every nozzle shares it, `z_hop` and wipe, fitted hardware such as `auxiliary_fan`, the extruder count and per-extruder vectors, the variant layout ([Printer rule 2](extruder-variants.md#printer-machine)) |
-| Model: one `machine_model`, which for an IDEX printer includes its mode | the default-nozzle preset where the bundle hangs its other nozzle presets off it; otherwise `fdm_<vendor>_<model>_common` | `printable_area`, `printable_height`, `bed_exclude_area`, the model's start G-code, a COPY or MIRROR mode's settings |
-| Nozzle: the selectable preset | none | `printer_model` and `printer_variant`, which name the preset's model and nozzle and stay in every preset as the tree writes them; `nozzle_diameter`, `min_layer_height`, `max_layer_height`, `default_print_profile`, `default_filament_profile`, retraction the vendor tunes per nozzle |
-
-A family may split once more, into toolhead or revision groups that exist only within it:
-`fdm_<vendor>_<family>_common` → `fdm_<vendor>_<family>_mk1_common`. A split that crosses another axis is not a
-level: when every controller comes with every toolhead, a toolhead base under each controller base
-repeats the same values in each ([Balance 6](#balance)).
-
-| Process level | Base | Settings it determines |
-| --- | --- | --- |
-| Vendor | `fdm_process_common`, `fdm_process_<vendor>_common` | strategy: seam, wall order, infill and support patterns |
-| Printer family or variant layout | `fdm_process_<vendor>_<family>_common` (`fdm_process_arena_common`, BBL's `fdm_process_dual_common`) | speeds, accelerations and jerk of that motion system; the variant layout ([Process rule 4](extruder-variants.md#process)) |
-| Layer height × nozzle | `fdm_process_<vendor>_<lh>_nozzle_<n>` (BBL's `fdm_process_single_0.20`) | `layer_height`, line widths, shell layers, speeds scaled to the layer |
-| Quality × printer: the selectable preset | none | `compatible_printers`, and what is unique to that combination |
-
-| Filament level | Base | Settings it determines |
-| --- | --- | --- |
-| Material | `fdm_filament_<material>` in OrcaFilamentLibrary, shared by every bundle | material defaults |
-| Product | `<Product> @base` | `filament_id` (minted here, [ids](ids.md)), `filament_vendor`, `filament_type`, density, cost, the product's temperatures and cooling |
-| Printer or nozzle tune: the selectable preset | none | `compatible_printers` (always in its own file, [Rule 9](../SKILL.md#rules)), volumetric speed, flow ratio, pressure advance and retraction measured on that printer |
-
-**Equal where they must differ is a copy.** A key that follows a finer level, such as the layer-height
-limits and line widths that follow the nozzle diameter or `printable_area` that follows the bed, never
-moves above that level. When presets that differ in it carry the same value, the value was copied: leave
-it in the presets and report it (the [worked example](#worked-example-an-idex-family) has one).
-
-## Balance
-
-1. **One group, one base; use the existing one first.** A base is the home of the presets below it,
-   whatever its name. In a bundle whose presets are all one family, the vendor base is the family base,
-   so the family's values go there. In a bundle that hangs the other nozzles off the default-nozzle preset, that preset is the model's home.
-   Never create a base whose presets are exactly its parent's. Where two existing bases already serve
-   the same presets (a copied `fdm_machine_common` above the vendor's own base), the finer one is the
-   home, and merging the pair is a change of its own. Moving a key into an existing home adds no file.
-   A base value that no preset below it loads is dead: replace it with the group's value when there is
-   one; otherwise leave it and report it, since a future preset would inherit it.
-2. **A new base must stand for a level and pay for itself.** Its file costs five metadata keys and an
-   index entry, so create it only when it takes `k` keys off `n` selectable presets with
-   `(n − 1) × k > 6`, where a custom G-code value counts as one key per G-code line: what it removes
-   must outnumber what it adds. A model with two nozzles that share three short keys keeps them in both.
-3. **No ad-hoc bases:** never a base for presets that merely agree (the ones with 0.8 mm retraction),
-   and never a base with one preset below it.
-4. **Keep every selectable preset within four ancestors**, selectable parents included. When a level would push a preset past that, fold it into the level above or leave
-   its keys in the presets.
-5. **A default with exceptions.** A value that only some presets below a shared base load moves to that
-   base, whichever axis it follows, when two conditions hold. More presets load it than any other value
-   (on a tie the key stays in the presets), and `w − a > 1`, where `w` presets drop their copy and `a`
-   presets that take the key from the base and load another value, the built-in default included, must
-   now write theirs. Presets that write another value keep it and are unaffected. The base then holds
-   the group's default, and the exceptions stay visible in their own files.
-6. **One chain; the other axes stay in the presets.** `inherits` follows one axis. When presets vary
-   along several (bed size × controller × toolhead), first fill the existing homes by
-   rules 1 and 5. Then give new bases to the axis whose bases pay most: sum rule 2's count over its
-   bases, less the keys a re-parented preset must now write because it no longer inherits them from its
-   old parent; on a tie, follow the layering the bundle already has. Leave the other axes' keys in the
-   presets, and never repeat one axis's bases under each group of another. Outside BBL, whose synced
-   presets need theirs, add no `include` template for a second axis: the loader reads `include` only
-   since #15869 (2026-09-25), and an app that predates it ignores the key, so the template's settings
-   never reach the preset.
-
-Name a new base after its level ([base names](naming.md#bases)). The name must be unique in its bundle
-and must not equal a selectable preset's: two such presets load silently and the first in the index wins
-([uniqueness](naming.md#uniqueness)).
-
-## Restated values
-
-`candidates` lists every key a file writes that it would load unchanged without writing it. Delete it
-when the value is what the presets below the base that supplies it share: more of them load it,
-written or inherited, than any other value. A family that restates machine limits, clearances and
-G-code every other printer of the bundle loads from `fdm_klipper_common` drops its copies. When most
-presets below that base load another value, the match is a coincidence: keep the key, and move it to
-the level of the presets that share it. Keys of the nozzle level stay in the preset in
-either case.
-
-After a restructure the report still lists keys that are right where they are: the nozzle-level keys
-each preset keeps, and arrays a list-less multi-extruder base writes at its presets' width for
-`check --strict`.
-
-## Variant arrays on a base
-
-- The loader stores a base with its variant arrays resized to the base's own variant list, one variant
-  when it writes none, so an array on a narrower base reaches its presets as its first value, padded.
-  Move a variant array to a base only when the base declares the presets' variant list (and, for a
-  machine or process, their ids), moving the layout keys with it as
-  [Printer rule 2](extruder-variants.md#printer-machine) and [Process rule 4](extruder-variants.md#process)
-  ask; or when the presets load its first value anyway: every value is equal, or the presets are
-  list-less machines, which the loader cuts to one variant. `compare` catches a cut.
-- Write the array on the base at the width of the presets it serves, their `N`
-  ([sizing equation](extruder-variants.md#sizing-equation)), so `check --strict` judges the right width
-  where it reaches them. When the presets below a base need different widths (single- and
-  dual-extruder models on one base), leave the array in the presets, or on bases that each serve one
-  width.
-- On a list-less multi-extruder family base, declare the extruder count: `nozzle_diameter` and the other
-  per-extruder vectors at one entry per extruder. The base then has its presets' width, and
-  `fix-variant --strict` writes an array that reaches the presets at another width into the base once,
-  instead of into every preset.
-- Deleting a restated variant array leaves the preset on the inherited array. Plain `check` accepts
-  that; `check --strict` reports it when the inherited width differs, which is why a bundle held to
-  `--strict` restates the array at each preset's width.
-
-## Procedure
-
-1. **Snapshot** the tree before any edit, `fix-variant` included. After `fix-variant`, run `compare`: a
-   difference is a value its padding changed (it repeats the last value, the loader the first). Set that
-   value deliberately, then snapshot again as the baseline for the restructure.
-2. **List the candidates:**
-
-   ```bash
-   python3 .claude/skills/orca-profiles/scripts/shared_settings.py candidates --vendor "<Vendor>" --type machine
-   python3 .claude/skills/orca-profiles/scripts/shared_settings.py candidates --vendor "<Vendor>" --type machine --group-by printer_model
-   ```
-
-   It prints the [restated values](#restated-values), then, per base, the keys every selectable preset
-   below it loads with one value and how many of those presets write it themselves, and under
-   `default with exceptions` the values that pass [Balance 5](#balance), with `w` and `a`. With
-   `--group-by <key>` it groups the selectable presets by that key's value instead and names each
-   group's nearest common base, where a new base would go: `printer_model` for models, `gcode_flavor`
-   for firmware, `extruder_type` or `default_filament_profile` for toolheads, `filament_id` for
-   filament products, `layer_height` for processes. The report is evidence, not a plan: it cannot tell
-   a shared value from a coincidence or a copy.
-3. **Decide each key** by [Levels](#levels), [Balance](#balance) and
-   [Restated values](#restated-values): delete the restatements of shared values, move group values up
-   to the group's home, and create only the bases that pay.
-4. **Edit.** Each new base gets `"type"`, `"name"`, `"from": "system"`, `"instantiation": "false"`, no
-   `setting_id`, and `inherits` set to the presets' old parent. Point the presets' `inherits` at it and
-   delete the moved keys from them. Bump the version, then run `normalize`, `update-index` (it orders
-   parents first) and `generate-id --dry-run`, which must write nothing: bases take no id and presets
-   keep theirs.
-5. **In a bundle held to `--strict`, run `fix-variant --strict` now**, so it writes into the new bases.
-6. **Verify.** `compare` prints `0 difference(s)`, and every one-sided key it lists is a default.
-   `check` reports no error it did not report before, and neither does `check --strict` where the bundle
-   passes it. Then run the [authoring checks](../SKILL.md#creating-or-modifying-a-profile).
-7. **Report** each base added (name, level, presets below it, keys it holds), the keys left in presets
-   and why, the copies found, and the `compare` result.

-## Worked example: an IDEX family
-
-A Klipper bundle's IDEX family has 36 selectable machines (bed size 300, 400 or 500 × normal, COPY or
-MIRROR mode × 0.4, 0.5, 0.6 or 0.8 nozzle) that all inherit `fdm_klipper_common` directly and write 49
-keys each. `fix-variant` has widened their retraction arrays to two values and their machine limits
-to four.
-
-- **Restated.** All 36 restate 10 values that every other printer of the bundle loads from
-  `fdm_klipper_common`: three machine limits, the three clearances, wipe, `retract_before_wipe`, and the
-  layer-change and pause G-code. Delete them.
-- **Family.** All 36 load one value for 24 more keys: the other machine limits, `extruder_offset`,
-  retraction, `z_hop`, `single_extruder_multi_material`, `manual_filament_change`, the remaining G-code
-  except the start G-code, and thumbnails. A new family base, `fdm_<vendor>_<family>_idex_common`,
-  holds them, plus `nozzle_diameter` `["0.4", "0.4"]` for the extruder count: at least
-  `(36 − 1) × 24 = 840`.
-- **Model.** Each `printer_model` (a bed size in one mode) has four nozzle presets that share
-  `printable_area`, `printable_height` and a three-line `machine_start_gcode`: `(4 − 1) × 5 = 15`, so
-  one base per model, nine in all. The family does not hang its other nozzles off a default-nozzle
-  preset, so the model level here is a base.
-- **A coincidence.** The twelve 500 presets' `printable_height` 500 equals `fdm_klipper_common`'s, but
-  every preset of the bundle writes its own height and 300 is the most common. The 500 is the base's
-  leftover, not a shared value, so it stays on the model bases.
-- **A copy.** In COPY and MIRROR mode, every nozzle of a model carries the 0.4 nozzle's
-  `min_layer_height`, `max_layer_height` and `retract_lift_below`: 0.06, 0.3 and 0.2 on the 0.8 nozzle,
-  where normal mode has 0.12, 0.5 and 0.3. `candidates --group-by printer_model` lists the first and
-  last as shared by the model, and `max_layer_height` as restated from `fdm_klipper_common`, whose value
-  is also 0.3. They follow the nozzle, so they stay in the presets and are reported for tuning.
-- **Nozzle.** Each preset keeps `printer_model`, `printer_variant`, `nozzle_diameter`,
-  `min_layer_height`, `max_layer_height` and `retract_lift_below` beside its metadata.
-- **Result.** 36 full presets become 36 short ones on 10 new bases. `compare` reports 0 differences,
-  `check --vendor "<Vendor>"` passes as before, and `generate-id --dry-run` writes nothing.
-  `check --strict` reports more errors than before, because the deleted variant arrays now reach the
-  presets at `fdm_klipper_common`'s one value. `fix-variant --strict` writes those arrays into the
-  family base alone, after which `check --strict` passes for the family and `compare` still reports 0
-  differences.

-# Validating profiles

-./scripts/check_profile.sh --vendor "<Vendor>"           # development loop

-
-```bat
-scripts\check_profile.bat                        :: the same three, on Windows
-scripts\check_profile.bat -Vendor "<Vendor>"
-scripts\check_profile.bat profile_tool validate_slice
-```
-
-`check_profile.bat` is a shim around `check_profile.ps1`: same checks, same order, same logs. Its flags
-take PowerShell spellings (`-Vendor`, `-ProfilesDir`, `-Validator`, `-Download`, `-Refresh`,
-`-WorkDir`, `-LogLevel`), and positional check names are unchanged. `-p`, `-v` and `-l` are aliases,
-so `-v Elegoo -l 2` reads the same on both platforms. It passes `-ExecutionPolicy Bypass` because a
-default Windows client refuses to run a checked-out `.ps1` at all. The `.ps1` finds Python itself,
-probing `py -3`, then `python`, then `python3`; run the tool by hand with `py -3` for the same reason.
-
-Every check runs even after an earlier one fails; the script exits non-zero if any failed, and writes
-`logs/<check>.log` plus, on failure, `pr_comment.md` (the same report CI posts on the PR) under a
-per-user cache dir:
-
-| Platform | Cache dir |
-| --- | --- |
-| macOS | `~/Library/Caches/orca-profile-check` |
-| Linux | `${XDG_CACHE_HOME:-~/.cache}/orca-profile-check` |
-| Windows | `%LOCALAPPDATA%\orca-profile-check` |
-
-It is named apart from OrcaSlicer's own per-user dirs and sits outside the checkout, so every worktree
-shares one copy and each run overwrites its `logs/`. `--work-dir` / `-WorkDir` overrides it.
-
-When other worktrees or agents may run checks too, pass `--work-dir <a dir of your own>` from the start
-and capture the console output yourself: the shared `logs/` can belong to another run by the time you
-read them. With `--work-dir`, also pass `--validator` pointing at the cached nightly, so the new dir
-does not download it again:
-
-| Platform | Cached validator |
-| --- | --- |
-| Linux | `<cache dir>/validator/OrcaSlicer_profile_validator` |
-| macOS | `<cache dir>/validator/OrcaSlicer_profile_validator.app/Contents/MacOS/OrcaSlicer_profile_validator` |
-| Windows | `<cache dir>\validator\OrcaSlicer_profile_validator.exe` |
-
-Copying the cached `profile-fixtures/` into the new dir reuses the fixture archives; the fixture
-`manifest.json` is still downloaded on every run, so `validate_custom` needs the network either way.
-`another run is using <dir>` means a live run holds `<dir>/.lock`: leave it and use your own
-`--work-dir`. Only a `.lock` with no `check_profile` process alive is a crash leftover; delete it by
-hand.
-
-## The five checks
-
-| Check | Command it runs | Catches |
-| --- | --- | --- |
-| `profile_tool` | `python3 scripts/orca_profile_tool.py check` | index coverage **both ways**, preset-name collisions, files `normalize` / `update-index` would still rewrite, duplicate JSON keys, filament `compatible_printers`, `filament_type` array, conflict keys, variant strings and array widths and layout keys, dangling `default_materials`, id length, **all `setting_id` and `filament_id` rules** ([below](#orca_profile_toolpy-check)) |
-| `validate_system` | `validator -p resources/profiles -l 2` | load errors, missing filament `compatible_printers`, dangling `inherits` / `compatible_*`, duplicate `filament_id` per printer (`Ambiguous AMS filament match`), printer defaults that name no compatible system filament |
-| `validate_slice` | `validator -p … -s -l 2` | custom G-code expansion and unresolvable printer defaults, by slicing |
-| `validate_filament_subtypes` | `validator -p … -l 2 -f` | nothing extra; see below |
-| `validate_custom` | `validator -p <tree + fixture> -l 2` | a shipped preset name that a past release offered no longer resolving |
-
-**`-f` is a no-op.** It defaults to on, so the duplicate-`filament_id` check runs whether or not you
-pass it, and `validate_system` already fails on duplicates. The binary's own `--help` ("Off unless this
-flag is present") does not reflect that default.
-
-**A `--vendor` run reads differently from CI.** The validator's `-v` loads that vendor plus
-OrcaFilamentLibrary and nothing else, so every library tune whose `compatible_printers` names another
-vendor's printers fails `validate_system`, `validate_filament_subtypes` and each `validate_custom`
-fixture with thousands of `references unknown compatible_printers "Bambu Lab …"` lines. Under
-`--vendor`, `profile_tool` and `validate_slice` are the meaningful results; for the other three, filter
-the log for your vendor's files and treat only those lines as findings. The unscoped run is the CI
-result; run it before the PR.
-
-### `validate_custom`: the backward-compatibility gate
-
-It downloads one fixture archive per past release (v1.9.0 onwards) of *generated mock* user presets: a
-`<vendor>_<preset>_orca_test` copy of every system preset that release shipped, cut with the
-validator's own `-g 1` mode. It unpacks each over a copy of the current tree and loads it. Each entry
-holds only `inherits` plus a canned diff, so the one failure it adds over `validate_system` is a shipped
-preset name disappearing. This is what makes a rename, a deletion or an `instantiation` flip a CI
-failure rather than just a user complaint, and the reason `renamed_from` is mandatory.
-
-The whole current tree sits under each fixture, so every `validate_system` error fails
-`validate_custom` too: fix `validate_system` first. Under `--vendor` it copies only the top-level index
-files, `<Vendor>/` and `OrcaFilamentLibrary/`, and picks fixtures by the index's display `name`
-(`Bambulab` for `BBL`), not the file stem; fixture presets without that prefix are covered only by an
-unscoped run, and it warns `validate_custom checked nothing` when none match.
-
-### `validate_slice`
-
-It slices a two-colour cube on every instantiable printer in the tree, sequentially, forcing the prime
-tower. It selects `default_print_profile` and the first `default_filament_profile`, then updates
-compatibility; that update can select a different compatible preset. Confirm the intended defaults
-yourself rather than treating a passing sweep as proof that those exact presets were sliced.
-
-A printer fails if it cannot be selected, falls back to a Default preset, throws, produces no G-code,
-or emits no `CP TOOLCHANGE START` (`change_filament_gcode` never expanded). Non-default processes and
-filaments get no dedicated coverage; [slice them on a copy](#checking-a-copy-of-the-tree). In the
-default set, a bundle without a `machine/` folder is recorded as SKIP; naming `validate_slice`
-explicitly for it fails (`No instantiable printer presets found for vendor OrcaFilamentLibrary`). The
-validator logs `[error]` lines that do not fail a check (such as `could not found extruder_type`); only
-each check's PASS or FAIL counts.
-
-## `orca_profile_tool.py check`
-
-`check` is one subcommand of the tool that also owns `fix-variant`, `generate-id`, `normalize`,
-`trim` and `update-index`; [ids.md](ids.md#the-tool) has the writing half.
-
-| Catches | Scope | Function in the tool |
-| --- | --- | --- |
-| two files in one bundle claiming one type + name, indexed or not | per vendor | `check_preset_name_uniqueness` |
-| a file on disk that no `*_list` references (**an error, not a warning**) | per vendor | `check_index_coverage` |
-| an index entry whose `name` disagrees with the file, or whose `sub_path` is missing | per vendor | `check_name_consistency` |
-| a file `normalize` would rewrite, an index `update-index` would rebuild | per vendor | `check_normalized` |
-| duplicate JSON keys in a file | every file read | the JSON loader |
-| an instantiated non-library filament with no non-empty `compatible_printers` of its own | per vendor | `check_filament_compatible_printers` |
-| `extruder_clearance_radius` alongside `extruder_clearance_max_radius` | per vendor | `check_conflict_keys` |
-| a scalar `filament_type` (`"filament_type": "PLA"`); the five other filament vectors `normalize` arrayifies surface as `normalize would convert <field> to an array` | per vendor | `check_vector_type_keys`, `check_normalized` |
-| a variant string the two enums cannot build (a dead variant, a legacy spelling included), a variant list naming one variant twice, an `extruder_type`, `nozzle_volume_type` or `default_nozzle_volume_type` that is not an enum name ([variant names](#variant-names)) | per vendor | `check_variant_names` |
-| a variant array not exactly `variant length × stride` wide in a selectable preset that writes it (with `--strict`, also in one it reaches); machine variant layout keys that disagree; a process id array that does not pair each variant ([variant arrays](#variant-arrays)) | per vendor | `check_variant_arrays` |
-| a declared `filament_id` longer than 8 characters | per vendor | `check_filament_id_length` |
-| a `default_materials` name, or a `default_filament_profile` name, matching no filament file ([below](#default-material-references)) | per vendor | `check_machine_default_materials` |
-| per-key warnings for ignored options, **filament files only** | per vendor | `check_obsolete_keys` |
-| `setting_id` uniqueness, every `filament_id` rule, and `machine_model` names duplicated across bundles | **tree-wide, ignoring `--vendor` entirely** | `check_setting_id_uniqueness`, `check_filament_ids`, `check_machine_model_name_uniqueness` |
-
-Because the id and model-name checks stay tree-wide, a vendor-scoped run can and does fail on another
-vendor's files, and it saves seconds, not minutes.
-
-Unscoped, the per-vendor pass covers every bundle. The only exclusion is the stray `user/` directory
-(below); OrcaFilamentLibrary is held to the same rules as any vendor, its sole exemption being that a
-library filament may leave `compatible_printers` empty. `check_normalized` covers every bundle with an
-index.
-
-Notes that matter:
-
-- Exit codes: **0** clean, **1** errors found, **2** argparse misuse. Warnings never change the exit
-  code.
-- A nonexistent `--vendor` is a hard error: `[ERROR] unknown vendor "<V>" in <dir>`, exit 1.
-- `--vendor ""` means all vendors; `check_profile.sh` relies on that. `--vendor` is repeatable
-  (`check --vendor A --vendor OrcaFilamentLibrary`); `check_profile.sh` takes one.
-- A **stray directory** under `resources/profiles/` still gets counted as a vendor by the per-vendor
-  pass and warned about (`No profiles found for vendor: <dir> at …/<dir>.json`, and the "Checked
-  vendors" count goes up by one): usually an emptied folder, or a `user/` left by a direct validator
-  run. An unscoped `check` skips `user/` by name; `--vendor user` still checks and warns about it.
-  `normalize`, `trim` and `update-index` ignore strays too: they define a bundle as *a directory with a
-  matching index file*.
-- Each remedy is printed once for the whole run, not once per file, as a `[WARNING]` under the errors
-  (`2 unreferenced file(s) above: delete them, or run … update-index`). Read those lines: they name the
-  command that fixes the batch.
-- When there are errors or warnings, the trailing summary suggests `normalize`. That is right for the
-  shape errors and misleading for everything else: an id error needs `generate-id`, a dangling
-  `default_materials` needs a human.
-- Other options: `--dry-run` on every writing command, `--profiles DIR` to point any command at another
-  tree, `--profile-type` to narrow `normalize`, `trim` and `update-index` to one type
-  ([ids.md](ids.md#the-tool)).
-- `resources/profiles/check_unused_setting_id.py` is a legacy BBL-only diagnostic, not part of
-  profile CI. Use `orca_profile_tool.py check` for current id validation.
-
-### Obsolete keys
-
-`check` always reports per-key warnings for obsolete options in filament profiles. Its normalization
-check also rejects obsolete keys across all preset types (`normalize would remove <key>`); `normalize`
-removes them.
-
-### Default-material references
-
-The materials check finds `default_materials` / `default_filament_profile` entries naming a preset that
-does not exist. It reads each `machine/` file's own key (a model's `default_materials`, a variant's
-`default_filament_profile`; a file that writes both is checked on `default_materials` only) and accepts
-any `name` found in the vendor's or OrcaFilamentLibrary's `filament/` files, bases and unindexed files
-included. The three authoring errors it surfaces are `,` instead of `;`, wrong case (`@system`), and a
-whole `;`-joined string stuffed into one array element. Only the validator (`validate_system`) requires
-an instantiated system filament that is compatible with each variant.
-
-### Variant arrays
-
-`check_variant_arrays` composes every selectable preset the loader's way (the parent, then each
-`include` in order, then the file's own keys; a filament's `inherits` may fall through to
-OrcaFilamentLibrary) and holds each key of [the four variant sets](extruder-variants.md#the-four-key-sets)
-that the preset writes itself to exactly its `variant length × stride`
-([widths](extruder-variants.md#widths)). The variant length is the length of the composed preset's
-own `*_extruder_variant` list; without one, a machine's is the number of variants its
-`extruder_variant_list` offers, else its extruder count (the list's default is one
-`Direct Drive Standard` per extruder), and a process's or filament's is 1. Any other width is an
-error, one value included and even when every value is the same. A key the preset does not write
-takes what reaches it, the default or an array it inherits or includes, which the loader resizes; it
-is not checked. A base is not judged on its own: what it writes counts only where it reaches a preset
-that does not override it.
-
-`check --strict` also holds every selectable preset to its own width for each key that reaches it,
-so a preset whose variants differ from those of the file its array comes from restates the array
-(the error names that file). That is BBL's practice and the target for new printer-specific presets;
-CI runs `check` without `--strict`.
-
-An id array that reaches a selectable preset, `printer_extruder_id` or `print_extruder_id`, written or
-inherited, must have one entry per entry of its variant list on any printer. This rule and the
-machine layout rules below judge the composed preset without `--strict`, whichever file writes the
-keys. Beside a written variant list this rule reports it instead of the width
-rule, so it is reported once. A process that
-lists variants without `print_extruder_id` gets a **warning** when a variant repeats (every entry then
-reads as extruder 1, so the repeated variant is unreachable), nothing otherwise.
-
-On a machine the layout keys are held to [Printer rules 1–4](extruder-variants.md#printer-machine),
-every failure an error unless marked:
-
-- With `extruder_variant_list` written: the list has one entry per extruder, as many as
-  `nozzle_diameter`; every variant starts with its extruder's `extruder_type`;
-  `default_nozzle_volume_type` names a nozzle volume type that extruder lists;
-  `printer_extruder_variant` is the list flattened extruder-major and `printer_extruder_id` gives each
-  entry its 1-based extruder (an id array left out reads as extruder 1 everywhere, which passes when
-  those are the flattening's ids). Without the pair, the list may offer one variant in total.
-- With the pair written and no `extruder_variant_list`: one variant per extruder at most. A pair that
-  `single_extruder_multi_material` off would replace with the default at load is a **warning**; a pair
-  the rebuild would leave as it is passes.
-
-It does **not** see a base's own resize: it composes at the width each file wrote, so an array wider
-than a base's list, which the loader cuts before any child inherits it, passes even with `--strict`
-([composition](extruder-variants.md#padding-truncation-and-composition)). Nor does it see per-extruder
-vectors outside the sets (`extruder_offset`, `printer_extruder_options`, …), which no variant list
-sizes. What a variant holds (a High Flow variant copied from Standard, a variant inserted at the wrong
-index) is review work
-([item 14](review-checklist.md#14-per-extruder-vectors-not-checked-and-variant-arrays-widths-and-layout-checked));
-whether it is a name the engine can select at all is `check_variant_names`'.
-
-`python3 scripts/orca_profile_tool.py fix-variant` resizes every array the width rule rejects in the
-selectable preset that writes it, leaves bases alone and adds no key: extra values are dropped, missing ones
-repeat the last value (the last normal/silent pair at stride 2; a lone value fills normal and silent
-alike). It leaves the variant lists and id arrays to you, since they address the variants rather than
-fill them. `fix-variant --strict` then also writes each key that reaches a selectable preset at
-another width: into the most general file on the way down to the preset whose own width is the
-preset's and whose selectable presets taking it all need that width, else into the preset itself.
-Presets of every bundle count towards that agreement; `--vendor` limits the files written and
-`--dry-run` previews. The loader pads with the first value where `fix-variant` repeats the last, so a
-padded array need not load as before, and
-trimming deletes values: when the extra values were meant as per-extruder or per-variant values,
-declare the variant layout instead ([Printer rule 2](extruder-variants.md#printer-machine)) and keep
-them. `fix-variant` moves no value, so a family whose presets all wrote one value repeats the widened
-array in each; put it on the family's base afterwards ([shared bases](shared-bases.md)).
-
-### Variant names
-
-`check_variant_names` reads the four list keys plus `extruder_type`, `nozzle_volume_type` and
-`default_nozzle_volume_type` of every preset the bundle's index references, bases included, and holds
-each entry to the names the engine's two enum maps define (`s_keys_map_ExtruderType`,
-`s_keys_map_NozzleVolumeType`, read from `PrintConfig.cpp` on every run). The bundle's own files are
-judged, not the composed config: a bad string is the writing file's error, once. Every finding is an
-error, and no bundle is exempt: BBL, whose bundle is imported from BambuStudio, is held to OrcaSlicer's
-enums like any other.
-
-- A variant string outside `<extruder type> <nozzle volume type>` is a **dead variant**: it still
-  counts toward the variant length the arrays are sized by, so the values written for it silently never
-  reach the G-code. `Hybrid` too, which is runtime-only, and an empty entry. A name BambuStudio's enum
-  has and OrcaSlicer's lacks is dead here as well, and passes with no tool change once the engine gains
-  that nozzle volume type.
-- A legacy name the loader still rewrites in these keys (`Normal` → `Standard`, `Big Traffic` →
-  `High Flow`) is an error that names the enum name to write; the profile has to spell the enum
-  name. `DirectDrive` is only rewritten in `extruder_type`, so a variant string carrying it is dead.
-- A variant list naming one variant twice is an error: the lookup returns the first equal string, so
-  the repeat is unreachable and its value sits at an index no extruder reads. A filament list takes
-  strings, `extruder_variant_list` takes them per extruder, and a process takes `(extruder id, variant)`
-  pairs — one string on two extruders is two pairs, not a repeat.
-- An `extruder_type`, `nozzle_volume_type` or `default_nozzle_volume_type` value that is not an enum
-  name is an error: they are enum options, so an unknown value fails the validator's load of the
-  whole bundle, while the app silently loads the option's default instead. A legacy spelling
-  (`DirectDrive`, `Normal`, `Big Traffic`) and `Hybrid`, an enum value no profile writes, are errors
-  too.
-
-The variant *order*, the choice of variants, and the values themselves are not checked.
-
-### `normalize` and `update-index` are part of the check
-
-`check` fails when either command would still change something, so they are not optional polish: the
-file that gets reviewed has to be the file that ships. What `normalize` changes is narrow and fixed:
-
-- adds a missing `type`;
-- deletes a `version` or `is_custom_defined` key from a *preset* file;
-- deletes six print-speed keys from filament profiles (`initial_layer_print_speed`, `outer_wall_speed`,
-  `inner_wall_speed`, `infill_speed`, `top_surface_speed`, `travel_speed`);
-- deletes the obsolete keys the loader ignores (the `ignore` set in `PrintConfigDef::handle_legacy`),
-  across preset types;
-- resolves the `extruder_clearance_*` conflict pair by keeping the larger;
-- arrayifies six filament options (`filament_type`, `filament_cost`, `filament_density`,
-  `temperature_vitrification`, `filament_max_volumetric_speed`, `filament_vendor`);
-- hoists `type`, `name`, `renamed_from`, `inherits`, `from`, `setting_id`, `filament_id`,
-  `instantiation` to the front.
-
-A file it changes is then rewritten whole: tab-indented, LF, one trailing newline, keys reordered. A
-file committed with CRLF line endings therefore changes on every line; read the diff before committing
-it.
-
-**Set `type` explicitly when authoring.** For a file in `machine/` without it, normalization guesses
-`machine` only if its name contains `nozzle` (case-insensitive), otherwise `machine_model`. That
-heuristic cannot reliably classify shared machine bases or unusually named variants.
-
-The tool's obsolete-key set is checked against the loader's ignore list by a unit test. Active options
-are preserved, including live keys whose *values* the loader rewrites (`extruder_type`: `DirectDrive` →
-`Direct Drive`; the variant-string keys: `Normal` / `Big Traffic` → `Standard` / `High Flow`), and so are
-legacy key names the loader migrates (such as `extruder_clearance_max_radius`).
-
-Two things it therefore does **not** enforce:
-
-- **Formatting and key order on their own.** A file with none of those problems is skipped entirely, so
-  4-space indent, a missing trailing newline, and a file that leads with `compatible_printers` all pass
-  `check`. They stay latent until something else trips `normalize` and the whole file reformats inside
-  an unrelated diff. (`normalize --force` rewrites every file; do not run it on a shipped bundle.)
-- **A misspelled setting key.** `inital_layer_height` and `sparse_infill_densiti` pass `check` cleanly.
-  Verify new keys against `src/libslic3r/PrintConfig.cpp` and the loader's legacy handling
-  (`PrintConfigDef::handle_legacy`: renamed keys, rewritten values and ignored keys).
-
-`check` does not catch a dangling `default_print_profile` either; check that name by hand.
-
-## The validator binary
-
-Built from `src/dev-utils/OrcaSlicer_profile_validator.cpp` with `-DORCA_TOOLS=ON`. Both scripts use a
-local build under `build*/` when one exists, else they download the nightly into the `validator`
-subdirectory of the cache dir. `check_profile.sh` searches Release, then RelWithDebInfo, then Debug
-(each under `build*/src/<config>` and `build*/*/src/<config>`), then single-config `build*/src`, and
-prefers a host-architecture build tree; `check_profile.ps1` tries Release, RelWithDebInfo, MinSizeRel,
-then Debug. A stale local build is used silently; `--download` / `-Download` skips local builds and uses the
-nightly. The download and the fixtures stay cached until `--refresh` / `-Refresh`, so
-`--download --refresh` (`-Download -Refresh`) matches CI exactly. Windows looks for
-`OrcaSlicer_profile_validator.exe`.
-
-If your build lives somewhere else, point at it with `--validator` / `-Validator`, or set
-`ORCA_PROFILE_VALIDATOR` (`$env:ORCA_PROFILE_VALIDATOR` in PowerShell).
-
-| Flag | Meaning |
-| --- | --- |
-| `-p <dir>` | profile tree (also becomes the data dir) |
-| `-l <n>` | log level; CI uses 2 |
-| `-v <Vendor>` | load only that vendor **plus** OrcaFilamentLibrary |
-| `-s` | slice sweep |
-| `-o <dir>` | with `-s`, save each printer's G-code there |
-| `-f` | no-op (see above) |
-| `-g 1` | regenerate user-preset fixtures; takes a value, and wipes the user preset dir first |
-
-On ARM64 Linux the nightly is x86-64 only: the script warns and downloads anyway, producing a binary
-that will not run. Build it locally with `-DORCA_TOOLS=ON` and pass `--validator`.
-
-Running the validator directly uses the profile tree as its data directory and can create `user/`
-there. Prefer the wrappers, which stash existing user presets and restore them afterward. After a
-direct run, inspect `user/` and remove only empty directories created by that run; fixtures or
-pre-existing user files may be present.
-
-## Checking a copy of the tree
-
-Use `--profiles DIR` on the Python tool and `-p DIR` on the validator. The wrappers' `--profiles` /
-`-ProfilesDir` passes the tree to both, so one run validates a copy fully:
-
-```bash
-./scripts/check_profile.sh --profiles "<tree>"
-# Windows: scripts\check_profile.bat -ProfilesDir "<tree>"
-```
-
-To slice a process or filament that is not a printer's default, or to read the G-code, work on a copy:
-copy `resources/profiles` and `resources/info` into one scratch dir (the validator reads `info/` next to
-the tree), point the printer's `default_print_profile` or first `default_filament_profile` at the preset
-in the copy, and run the validator with `-o`:
-
-```bash
-<validator> -p <scratch>/profiles -v "<Vendor>" -s -o <gcode dir>
-```
-
-Each printer's G-code is saved as `<vendor name>__<printer>.gcode`; its embedded config
-(`; print_settings_id = …`, `; filament_settings_id = …`) shows what was actually sliced.
-
-## Testing in the app

-Editing this checkout's `resources/profiles` does not update a separately installed application. Test
-with a build using the edited resources and a bumped bundle version: the updater installs newer bundles
-under `<data_dir>/system/`, and the preset cache also depends on the bundle version. Use Help ▸ Show
-Configuration Folder to locate the active data directory:
-
-| Platform | Default data directory |
-| --- | --- |
-| macOS | `~/Library/Application Support/OrcaSlicer` |
-| Linux | `$XDG_CONFIG_HOME/OrcaSlicer`, or `~/.config/OrcaSlicer` when unset |
-| Windows | `%APPDATA%\OrcaSlicer` |
-
-A portable `data_dir` next to the executable takes precedence. Use a separate test configuration for a
-clean-install check; preserve the normal configuration and user presets.

-## CI
-
-`.github/workflows/check_profiles.yml`, job **"Check profiles"**, runs on `pull_request` into `main` or
-`release/*` touching `resources/profiles/**`, `resources/printers/**`, `scripts/**`,
-`src/libslic3r/PrintConfig.cpp` (where the tool reads the variant key sets) or the workflow itself.
-There is no push trigger: a direct push to main runs no profile validation.
-
-The job opens with `python3 -m unittest discover -s scripts/tests -t scripts`, the tool's own unit tests
-(run them locally after changing `scripts/`, with `py -3` on Windows, and keep `-t scripts` or the
-imports fail). That step is deliberately **not** `continue-on-error`: a broken tool makes everything it
-then says about the profiles worthless. Every check after it is `continue-on-error` with a final gate,
-so one run reports all five results. On failure a second workflow posts or replaces a single PR comment
-marked `<!-- profile-validation-comment -->`, holding the start of each failing log (30 KB per check,
-12 KB per `validate_custom` fixture; reproduce locally for the full list); it deletes the comment once
-the run is green.
-
-The job name is also the required check for the delegated-merge bot, which lets a vendor maintainer
-self-merge a PR limited to their own `resources/profiles/<Vendor>/` folder with no human review, so
-whatever CI does not check is what ships unreviewed. Its denied patterns refuse `^scripts/` and any
-`.py`, so a PR that touches the tooling always needs a maintainer.

-# Vendor bundles
-
-A bundle is `resources/profiles/<Vendor>.json` (the index) plus `resources/profiles/<Vendor>/`. The
-**vendor id is the filename stem**, not the `name` inside; the two may differ (`BBL.json` is named
-"Bambulab"). Asset paths and the `setting_id` formula use the id; the `validate_custom` fixture prefix
-uses the `name`.
-
-## The index
-
-```json
-{
-    "name": "Phrozen",
-    "version": "02.04.00.03",
-    "force_update": "0",
-    "description": "Phrozen configurations",
-    "machine_model_list": [ { "name": "Phrozen Arco", "sub_path": "machine/Phrozen Arco.json" } ],
-    "machine_list":       [ … ],
-    "process_list":       [ … ],
-    "filament_list":      [ … ]
-}
-```
-
-The loader reads `name`, `version`, `url` and the four `*_list` arrays. `description` is only logged;
-`force_update` is read by the profile updater, never by the loader. `sub_path` is relative to the
-**vendor folder**.
-
-| List | Holds |
-| --- | --- |
-| `machine_model_list` | `machine_model` records (the printer product) |
-| `machine_list` | printer variants **and** shared machine bases |
-| `process_list` | selectable processes **and** shared process bases |
-| `filament_list` | selectable filaments **and** shared filament bases |
-
-### Three registration rules
-
-1. **Everything is registered, bases included.** Every preset file on disk has exactly one entry in the
-   matching list, and no unindexed preset file is left in the tree.
-2. **Parents before children, includes before includers.** The lists load processes first, then
-   filaments, then printers, each in index order, and `inherits` and `include` resolve only against
-   presets of that type already loaded from it. A parent
-   listed after its child produces `can not find inherits <parent> for <child>` and the bundle is
-   discarded; an include listed after its includer is `can not find include`, a counted error that
-   leaves the includer without those keys.
-3. **The index entry's `name` equals the `name` inside the `sub_path` file.** `renamed_from` does not
-   excuse a mismatch.
-
-All three are `check` errors, and `update-index` writes an index that satisfies all three from the
-files on disk, including the dependency ordering (parents and templates before the presets that use
-them, then, in name order, entries that neither depend on nor are depended on by another entry of their own
-list, and any entry on a dependency cycle). Hand-editing the index is
-fine for a one-line addition, but the committed result must equal what `update-index` writes, because
-`check` compares them.
-
-The loader itself reports none of this: an unregistered file, or an entry with a misspelled key
-(`"subpath"`), is silently dropped. (A misspelled `sub_path` value is a `check` error naming the entry.)
-
-`BBL/cli_config.json` and, in `BBL/filament/`, `filaments_color_codes.json`, `filament_id_map.json`,
-`filament_name_map.json` and `support_recommended_params.json` are auxiliary data files read by path,
-not presets. The last three carry a `type` key and look like presets; the tool excludes all five from
-preset maintenance.
-
-## `version`
-
-Four components, `MM.mm.pp.bb`, compared as a version number in which the fourth is folded into the
-third (`patch × 100 + build`). Write all four components, zero-padded.
-
-- **Bump the version for every bundle the change touches.** The app installs bundled profiles only
-  when their version is newer than the installed one, and the `.opc` preset cache is also keyed on
-  the version. Nothing in profile CI checks the bump.
-- **Keep the last component ≤ 99.** `02.04.00.100` and `02.04.01.00` both read as
-  `2.4.100`. A bundle that
-  reaches `.99` carries into the third component (`02.03.02.99` → `02.03.03.00`).
-- An **absent** version is worse than a stale one: it reads as `0.0.0`, which is not a valid version.
-  `check` and the validator still pass, but the vendor is dropped from the setup wizard entirely and gets no preset cache. Confirm the key exists. An
-  *unparseable* version is not silent: it discards the whole bundle (`vendor <V>'s config version: <s>
-  invalid`).
-
-## Common preset keys
-
-| Key | Value |
-| --- | --- |
-| `type` | `machine_model`, `machine`, `process` or `filament` |
-| `name` | the preset name, the identity every reference uses; the filename is *not* authoritative |
-| `inherits` | the parent's exact `name`: no path, no `.json` |
-| `include` | a template's exact `name`, or an array of them, layered under this preset's own keys ([below](#inherits-and-include)) |
-| `instantiation` | the **string** `"true"` (selectable) or `"false"` (base) |
-| `from` | `"system"` for shipped presets |
-| `setting_id` | generated; required on instantiated presets, forbidden on bases |
-| `renamed_from` | `;`-separated old names this preset supersedes ([below](#renamed_from)) |
-
-These are config-preset keys; `machine_model` records have their own
-[key set](machine-profiles.md#machine_model-a-record-not-a-config-preset). Keep `from` as `"system"`:
-the bundle loader ignores it, but loading the file as a CLI config accepts only `system`, `user` or
-`User` and handles their inheritance differently.
-
-`instantiation` is the one metadata key the validator gates: a missing key or any value other than the
-strings `"true"` / `"false"` is a counted error (`Missing instantiation attribute for <name>`) that fails
-the validator, though the preset still loads and is treated as selectable. A file with no
-`instantiation` whose name contains `gcode`, or that has no `name`, silently becomes an include-only
-template. A JSON boolean `true` fails harder: it takes the **whole vendor bundle** down.
-
-## `inherits` and `include`
-
-`inherits` resolves by exact name **within the same bundle**, plus one exception: filaments may inherit
-from OrcaFilamentLibrary, which is loaded first. Vendor-to-vendor inheritance always fails, and an
-unresolved `inherits` discards the bundle. You can inherit from an instantiated preset as well as from a
-base.
-
-`"include": ["<name>", …]` (or one bare name) pulls in `instantiation: "false"` presets of the same type
-from the same bundle (never the library), registered before the includer. It shares a block of keys
-between presets that do not share a parent: a variant layout, a G-code template. Only `"false"` presets
-can be included, so a name that resolves to nothing (misspelled, registered after the includer, or a
-selectable preset) is a counted error (`can not find include`) and the preset loads without it.
-
-**How a preset's config is composed:** start from the parent's stored config (a root starts from the
-built-in defaults), apply each preset named in `include` in the order listed, then the preset's own
-keys. Later layers win, so precedence is own keys > later includes > earlier includes > the `inherits`
-chain. Only then is every variant key of the composed config resized to its variant length
-([widths](extruder-variants.md#widths)), and keys of another preset type removed. The two routes hand
-down different widths:
-
-- **`inherits` hands down the resized config.** A base is stored *after* its own resize, at the length
-  of its own `*_extruder_variant` (one variant for a base of any type that writes none, whatever its
-  extruder count). A child therefore inherits the base's arrays at the base's width: an array wider than
-  that is cut to its first values before any child sees it, and a child that adds variants gets those
-  first values padded. So widen an array only on a preset whose own variant list already has the
-  entries; a wide array on a narrow base is silently lost at load, and `check`, which composes at the
-  width each file wrote and judges selectable presets only, misses that cut.
-- **`include` hands down the template's diff, at its pre-resize width.** An included preset contributes
-  every key where its own composed config (its parent, its own includes and its own keys) differs from
-  the built-in defaults, taken *before* its resize. So keys the template inherits are passed on too,
-  arrays it writes arrive at the width its file wrote, and a key it sets to the built-in default value
-  is not passed on at all, so it cannot override what the includer inherited. Resizing happens on the
-  includer, not on the template.
-
-## `renamed_from`
-
-One JSON string, `;`-separated for several old names.
-
-- Write `"A;B"`, never `"A ; B"`: a space after a `;` is skipped, but a space before it stays part of
-  the name (`"A "`), which can never match.
-- When `renamed_from` is **absent** and the name contains `@`, the loader auto-adds the `@`-removed form
-  (`X @Y` → `X Y`) as a rename alias. Declaring an explicit `renamed_from` **suppresses** that, so a
-  preset that needs both the `@`-removed form and a real old name must list both; a preset that gains
-  a `renamed_from` without it quietly loses its `X Y` alias.
-- It rescues names stored **outside** the tree: user presets and 3MF projects. It does **not** rescue
-  in-tree `inherits` (exact lookup), it does **not** satisfy the index-name rule, the validator reports
-  an in-tree reference that only resolves through it (`references renamed compatible_printers "OLD"
-  (now "NEW")`), and `machine_model` records never read it at all.
-- Only one preset may claim a given old name; two that do is a counted error
-  (`… was marked as renamed from "Y" … as well`). But the redirect is **inert while a live preset still
-  carries that name**, and nothing checks *that*, so a neighbour's `renamed_from` is no model.
-
-## Failure scopes
-
-| Scope | Cause |
-| --- | --- |
-| **Every vendor except OrcaFilamentLibrary, and all user presets** | a non-string where the index or a `machine_model` expects a string (`"version": 2` at the top level of an index, a numeric `name` or `url`, a non-string `nozzle_diameter` or other model key): `[json.exception.type_error.302] type must be string`, and the validator reports `Validation failed` |
-| **The whole vendor bundle** | index JSON parse error; unparseable `version`; a listed file missing or unparseable; a value its option cannot take, such as `nil` in a non-nullable key (`Failed loading configuration file`); unresolved `inherits`; two selectable presets with one name; empty or unknown `printer_model` / `printer_variant`; a filament resolving no `filament_id`; a JSON boolean `instantiation` |
-| **A counted error; the preset still loads** | `instantiation` missing or not `"true"` / `"false"`; keys belonging to another preset type (`contains incorrect keys: …, which were removed`); a non-string inside a `*_list` entry (`invalid value type for <key>`); an `include` naming nothing usable (`can not find include`, loads without it) |
-| **The rest of the file, logged only** | an array with a non-string element (`[0.4]`, `invalid json array`): that key and every key after it in the file are dropped, and no error is counted |
-| **One value, logged only** | a raw JSON number in a preset (`invalid json type for <key>`): the value is dropped and the exit code stays 0 |
-| **Nothing reported by the loader** | unregistered file; two bases with one name, or a base and a selectable preset with one name (the first in the index wins); misspelled setting key; missing bed, hotend or cover asset. `check` catches the first two; the others reach users |
-
-Deleting a file the index still lists surfaces as a *parse error* on line 1 (`unexpected end of input`), not "file
-not found".
-
-Selectable preset names are a **single namespace across every vendor**: a duplicate within one vendor
-is a hard bundle failure, and a duplicate across vendors is reported as `Found duplicated preset: <name>
-in vendor: <vendor>` and still counts as an error. `check` catches the within-bundle case earlier and
-more precisely, bases included, and including an *unindexed* twin, which is one `sub_path` edit away
-from silently becoming the parent every child resolves to (the first registered preset of a name wins,
-so index order decides). Base names, by contrast, repeat across bundles by design:
-every bundle may have its own `fdm_process_common` ([uniqueness](naming.md#uniqueness)).
-
-## Starting a whole new vendor bundle
-
-Nothing generates one; copy the smallest bundle that resembles the hardware. **`Voxelab`** is the
-minimal shape: a shared machine base, the model, one variant, a shared process base, two processes, and
-an empty `filament_list`, so the printer takes the library generics. Do *not* start from a bundle that
-carries local `fdm_filament_*` copies, which drift from the library, or filament presets that restate
-most of their parent, the style this skill advises against.
-
-Write the machine files **last**, so you only visit them once:
-
-1. **Choose the names first**: model, variant(s), process(es). Everything else references them
-   ([naming.md](naming.md)).
-2. `resources/profiles/<Vendor>.json`: `name`, `version` (`01.00.00.00`), `force_update: "0"`,
-   `description`, and all four `*_list` arrays (empty is fine: `update-index` fills them once the files
-   exist, so this step only needs the bundle metadata to be right).
-3. The shared bases: `<Vendor>/machine/fdm_machine_common.json` and
-   `<Vendor>/process/fdm_process_common.json`, both `"instantiation": "false"` with no `setting_id`. For
-   a Klipper printer add your own `<Vendor>/machine/fdm_klipper_common.json` inheriting the machine
-   base; there is no shared one, because a `machine` preset can only inherit inside its own bundle.
-4. One selectable process per variant, each naming its variant in `compatible_printers`.
-5. Bed assets and `<Model>_cover.png`, all directly in `<Vendor>/`. None of them is needed for the
-   bundle to load, and nothing in CI checks them; but the bed files are inert unless the
-   `machine_model` names them in `bed_model` / `bed_texture`, and the cover is found by convention as
-   `<the name you gave the model in machine_model_list>_cover.png`.
-6. The `machine_model` record and the `machine` variants, now that every value they reference exists;
-   the minimum key sets and the `default_*` shapes are in
-   [machine-profiles.md](machine-profiles.md#machine-the-variant).
-7. Run the tool and validate: follow
-   [Creating or modifying a profile](../SKILL.md#creating-or-modifying-a-profile). `generate-id` is not
-   optional for a new bundle: the validator loads presets that have no `setting_id`, but `check` fails
-   every one of them.
-
-## `resources/profiles_template/`
-
-A separate tree (`Template.json` + `Template/`) holding filament and process templates. It is **not** a
-scaffold for shipped profiles: the app's "create a custom printer / filament" dialog reads it, so
-editing it changes what users get when they create a custom preset. `check_profile.sh`'s validator
-checks default to `resources/profiles` (redirectable with `-p`), and so does `orca_profile_tool.py`
-(redirectable with `--profiles`); neither covers this tree.

-# vendor-dispatch path is also what makes post_merge_profiles.yml call the OTA auto-publish API after
-# uploading - see post_merge_profiles.yml for both sides of that contract.
-#
-# Each run captures a timestamp, dispatches the needed OFL publishers, waits for
-# all of them to finish, then clears the pending-publish table once. Changes merged

-# Manager lists the asset, a maintainer attaches a changelog and hits Publish, and

 - If a term's established translation changes, update both the affected `.po` files and the glossary (`localization_glossary.tsv`, then regenerate) so they stay in sync.
 - Translate the *meaning*, not the words. Check what the string actually controls before translating it — English reuses one word for different things. `Flow ratio` (multiplier), `Flow Rate` (throughput) and `Flow Dynamics` (pressure compensation) are three different terms; `extruder` may mean the toolhead, the feeder motor, or the nozzle depending on the string.
 - Reuse one template per recurring message shape (`Failed to connect to …`, `Are you sure you want to …?`), even where the English wording varies.

-# Texture Displacement - Technical Notes
-
-Branch: `feature/texture_displacement`. Reference for the feature as it stands: what it does, how the
-algorithms work, and where the code lives.
-
-## What it does
-
-A paint-style gizmo (`GLGizmoTextureDisplacement`) that lets you:
-- Paint one or more "layers" onto a model's surface, each a height-map texture with its own
-  depth/tiling/rotation/offset/invert/tile-mode/projection-mode/blend-mode.
-- Pick a texture from a shipped library (`resources/textures/displacement/`) or import your own
-  (saved into `<data_dir>/textures/displacement/`, kept separate so app updates can't clobber it).
-- Combine overlapping layers with image-editor-style blend modes (Add/Subtract/Multiply/Divide).
-- Preview the true displaced result live, before baking (background job, not on the UI thread).
-- Preview via a fast GPU shader instead (no real geometry movement) for a lighter-weight alternative.
-- Bake into real mesh geometry on demand, restricted to the painted area only.
-- Remesh and subdivide so a low-poly model has enough vertices to show fine detail.
-- Unwrap a painted patch with a real CGAL LSCM parameterization and view it in a dedicated,
-  dockable 2D "UV Editor" pane.
-
-## Standard vs Pro mode
-
-A two-position slider in the panel header, right of the Dock/Undock button.
-
-**Pro** shows every mesh-preparation control; Remesh, Subdivide and Bake are run separately by the user,
-in whatever order they like.
-
-**Standard** hides all of it and folds one fixed recipe into the Bake button, because a height map only
-ever *moves vertices that already exist* - painting onto an imported 12-triangle box and pressing Bake
-would otherwise do nothing visible. Standard's Bake is:
-
-1. `plan_remesh()` + `replace_mesh_keep_all_paint()` - isotropic remesh to 1 mm, sharp edges above 40
-   degrees protected. Gives the subdivider an even starting density whatever the input looked like.
-2. `plan_adaptive_subdivision()` + `apply_adaptive_subdivision()` - feature-adaptive refinement, max
-   edge 20 mm, detail 0.02 mm, min edge 0.02 mm.
-3. `bake()` - the ordinary background displacement job.
-
-Both preparation stages are *planned* before the undo snapshot and *applied* after it, so a stage with
-nothing to do is skipped without leaving an empty undo step. The standalone Pro buttons share the same
-plan/apply split.
-
-**All three stages sit under one undo step.** `Plater::take_snapshot()` records the state *before* the
-change, so a single snapshot taken at the top of `bake_standard()` means one Undo returns the mesh to
-exactly what was imported. `TextureDisplacementBakeInput::take_snapshot` lets the caller say who owns
-the undo step - true for the Pro-mode button, false for the pipeline, whose background job commits long
-after that snapshot's scope has closed.
-
-The presets live in one place (`STD_*` constants) and `apply_standard_mode_presets()` pins the hidden
-controls to them every frame while Standard is active, so the live preview cannot disagree with what
-Bake will do. Switching to Standard also closes the subdivision preview, whose controls have just gone.
-
-One control survives into Standard: **"Added triangles (k)"**, the subdivision budget. It is deliberately
-*not* pinned - pinning would fight the user's own slider every frame - because unlike the rest of the
-recipe its right value depends on the part rather than on the method (a big model, or a fine texture,
-simply needs more triangles). Default 1500. The widget is one lambda shared by both layouts.
-
-Standard remeshes *after* painting, so the remesh has to preserve paint: `ModelVolume::restore_painting()`
-only remaps the four standard channels, so `replace_mesh_keep_all_paint()` additionally runs
-`TriangleSelector::remap_painting()` over the eight texture-displacement masks. The Pro Remesh button
-goes through the same helper. If the remap comes back empty the pipeline stops with a message rather
-than baking a flat mesh.
-
-## Architecture
-
-### Data model (per `ModelVolume`)
-
-Each of up to `TEXTURE_DISPLACEMENT_MAX_LAYERS` (8) layers gets its **own independent
-`FacetsAnnotation`** paint mask - the same `TriangleSelector`/`FacetsAnnotation` machinery every other
-paint gizmo (FdmSupports, Seam, MMU, FuzzySkin) already uses, just one full instance per layer slot
-instead of one per volume. This is what makes layered/blended painting work for free: the same triangle
-can be `ENFORCER` in layer 2's mask and layer 5's mask simultaneously, and at bake/preview time each
-layer displaces the surface left by the previous one (image-editor-layer semantics).
-
-Whole-stack settings (border handling, post-process smoothing) live beside the layers in
-`texture_displacement_options` (`TextureDisplacementOptions`), since they belong to no single layer.
-
-### Bake algorithm (`libslic3r/TextureDisplacement.cpp`)
-
-`build_texture_displacement(base_mesh, layers, facets_data, options)` is **accumulate-then-displace,
-and topology-preserving**: the returned mesh has exactly the input's vertices and triangles, in the
-same order - only the positions of displaced vertices differ.
-
-1. `its_compactify_vertices()` on a copy of the input. In practice a no-op (it only drops
-   *unreferenced* vertices, and preserves the order and indices of the rest). It is there to
-   guarantee the index alignment step 3 depends on.
-2. Area-weighted vertex normals of the **undisplaced** mesh, computed once. Every layer both projects
-   and displaces along these, so a vertex covered by several layers moves along one single well-defined
-   direction. Where the paint does *not* cover every triangle around a vertex, the normal is recomputed
-   from the painted triangles alone (the union over all layers, so it stays one direction per vertex):
-   on the rim of a fully painted top face the whole-mesh normal is the 45-degree bisector it shares with
-   the side wall, and displacing along that flares the rim outwards instead of raising it. Interior
-   vertices are unaffected - all their triangles are painted, so the two normals coincide. Paint
-   coverage per original triangle comes straight off `TriangleSplittingData::triangles_to_split`.
-3. For each layer in slot order: deserialize its stored paint mask into a `TriangleSelector` against
-   the **base mesh** (never against a previous layer's output), then
-   `selector.get_facets_strict(ENFORCER)` -> the painted patch. Two facts are exploited:
-   - `get_facets_strict()` returns the mesh's **entire** referenced vertex array regardless of which
-     state was asked for - only `.indices` is filtered by state. So `get_facets_strict(ENFORCER)`
-     and `get_facets_strict(NONE)` share identical vertex indexing, which is what lets boundary
-     detection be a plain index check instead of a position-hash lookup.
-   - The selector's vertex array *starts with* the mesh's own vertices (extra ones created where a
-     brush stroke split a triangle are appended after them), and `get_facets_strict()` emits the
-     referenced ones in order. Combined with step 1, **selector vertex index `i` is our vertex `i`**.
-     Split vertices live past the end of our array and are simply skipped - they sit on the paint
-     boundary anyway (splitting only happens at partial coverage).
-4. A vertex used by at least one **unpainted** triangle is a border vertex. Whether it moves is
-   `TextureDisplacementOptions::displace_border`, and it does by default. Nothing can tear: the bake is
-   topology-preserving, so a border vertex is *one* vertex shared by both regions and moving it simply
-   tilts the unpainted triangles that use it. Pinning it instead clamps the outermost ring of relief to
-   zero, which on a fully painted face collapses the pattern into a ring of steep ramps at the edge; it
-   is kept as an option for when the relief must not spill past the paint at all. Either way the border
-   drives the `edge_smoothing` falloff.
-5. Per interior vertex: sample the height texture (`sample_layer_height()`, see Projection methods)
-   and fold `height * depth_mm * (invert ? -1 : 1)` into that vertex's running total via the layer's
-   `TextureBlendMode` (see Blend modes). A `visited` set makes each layer fold in exactly **once**
-   per vertex, no matter how many of the patch's triangles share it - otherwise a Multiply/Subtract
-   layer would apply two or three times over depending on local triangle fan-out.
-6. Move each touched vertex along its (step 2) normal by its accumulated total.
-7. Optionally (`TextureDisplacementOptions::smooth_*`) relax the result - see Post-process smoothing.
-
-### Post-process smoothing
-
-`smooth_mesh_vertices(mesh, movable, strength, iterations)` - Laplacian relaxation, run after all layers
-have been folded in, restricted to the vertices flagged in `movable`. Each pass moves a movable vertex a
-`strength` fraction of the way to the average of its one-ring, read from a **snapshot** of the previous
-pass so the result does not depend on vertex order (a Gauss-Seidel sweep would smooth several times as
-hard at the end of the array as at the start). Neighbours come from a CSR-style adjacency built once per
-call. Topology-preserving, like the bake.
-
-Its job is to round off the hard steps a bitmap height map leaves behind - a different knob from
-`TextureDisplacementLayer::smoothing`, which blurs the *height map* before it is ever sampled.
-
-Two ways in, sharing one set of settings on the volume:
-- The **"Smooth result"** checkbox + "Smoothing (%)" / "Passes" ride along with Preview and Bake.
-  `movable` is exactly the set of vertices the displacement moved, so the untouched part of the model
-  keeps its exact geometry and the ring just outside the displaced set anchors the relaxation (the
-  relief cannot creep outward).
-- **"Smooth baked mesh now"** (`GLGizmoTextureDisplacement::smooth_model()`) applies the same settings to
-  the volume's *committed* geometry, for relief that is already baked in. `movable` there is the painted
-  triangles' vertices. Because smoothing never touches the triangle list, this is the one geometry
-  operation in the gizmo that keeps **every** paint channel verbatim - it saves and restores the eight
-  texture-displacement masks around `set_mesh()` rather than remapping or dropping them.
-
-**"Ignore outer ring"** (`smooth_skip_border`, on by default) drops the patch's own outermost ring of
-vertices from `movable`. That ring's neighbours *outside* the paint never move, so relaxing it drags the
-rim of the relief down toward the flat surface and the pattern comes out half-melted where it meets the
-edge. Held out, the border keeps the full depth the texture asked for and only the interior relaxes.
-Turning it off softens the outer edge deliberately (a blunter version of the per-layer edge-smoothing
-falloff). This is the *smoothing* rim, independent of whether that rim is displaced at all
-(`displace_border`, step 4 above); both default to keeping the border sharp.
-
-### Blend modes
-
-`TextureBlendMode` {Add, Subtract, Multiply, Divide}, per layer, applied per vertex against the
-total accumulated by the layers **below** it (lower slots). The quantity blended is a signed
-displacement in **mm**, not a pixel value.
-
-Add/Subtract are self-explanatory. Multiply/Divide are *scaling* operations and so need a unit
-convention: they treat the layer's own value as a **factor relative to 1 mm**. That makes `depth_mm`
-a gain, and - the property that makes a Multiply layer usable as a mask - a layer with depth 1 mm
-sampling a white (1.0) texel multiplies by exactly 1, i.e. leaves the layers below unchanged.
-Divide floors its divisor's magnitude at 0.05: a black texel samples to *exactly* zero, so the divisor
-really does hit zero in ordinary use, and an unbounded `1/0` would fling vertices thousands of mm away
-and poison the mesh's bounding box (and every plate/print-volume check downstream). The floor doubles as
-a cap on how far Divide can amplify the relief beneath it: at most 20x.
-
-The **lowest painted layer ignores its blend mode**: it has nothing beneath it, and Multiply/Divide
-against an implicit zero base would annihilate (or blow up) it. Enforced in
-`build_texture_displacement()` (the first layer to reach a given vertex always folds in additively) and
-surfaced in the UI, which labels that layer "Base layer" instead of offering a control that does nothing.
-
-### Projection methods
-
-Five choices per layer (`TextureProjectionMethod`), all funneling through `apply_uv_transform()`
-(scale by `1/tiling_scale`, rotate by `rotation_deg`, add `offset`). They are dispatched by
-`sample_layer_height()`, which returns a **height**, not a UV - because Triplanar takes three
-texture samples per vertex and so has no single UV that represents it.
-
-- **Triplanar** (default) - samples the texture on all three world planes (`(y,z)`, `(x,z)`, `(x,y)`)
-  and blends the three by the vertex's own normal raised to `TRIPLANAR_BLEND_SHARPNESS` (4). Hard-picking
-  the single axis most aligned with the normal instead is discontinuous wherever that dominant axis
-  flips: on a +X face the planar coordinate is `(y, z)`, on a -Y face it is `(x, z)`, so at the shared
-  edge `u` jumps. A weighted blend is continuous across the transition by construction, since the weight
-  of the axis being left behind falls smoothly to zero. This removes the hard *seam*; some cross-fade
-  blurring in the band right at a 90° edge is inherent to triplanar mapping. A genuinely seam-free wrap
-  around a box needs a real unwrap - that is what the LSCM mode is for.
-- **Cylindrical** - wraps around an axis through the patch centroid, axis auto-picked as the world
-  axis *least* aligned with the average normal (perpendicular to the outward radial normal, as a
-  cylinder's own axis would be). `u = angle * local_radius` (arc length in mm), `v = distance along
-  axis`. An approximation, not an exact fit for arbitrary geometry, and the axis/centre are not
-  user-overridable.
-- **Spherical** - longitude/latitude around the centroid, scaled by local radius. Same caveat.
-- **LSCM** - real UV unwrap via `MeshBoolean::cgal::parameterize_lscm()` (CGAL's
-  `Surface_mesh_parameterization` package, LSCM algorithm). Computed **once per patch** (not
-  per-vertex like the others - it's a single global least-squares solve), then each vertex looks up
-  its precomputed UV. Requires the patch to be a single topological disk (one connected component,
-  one boundary loop) - `compute_lscm_uvs()` returns empty and the layer falls back to Triplanar if not
-  (e.g. multiple disconnected painted islands, or a fully closed patch). CGAL's parameterizer needs a
-  mesh with no isolated/unreferenced vertices, but `get_facets_strict()` returns the *whole* mesh's
-  vertex array - so `compact_patch_with_map()` builds a clean sub-mesh plus an index map back to the
-  original vertex numbering, purely local to this file.
-- **ViewProjected** ("From view") - a flat projection along a fixed direction captured from the 3D
-  camera, like a slide projector. `capture_view_projection()` takes the camera's right/up axes,
-  transforms them into the volume's *local* frame (so the projection rides along if the part is later
-  moved), and stores them as `TextureDisplacementLayer::view_project_right/up` (unit vectors, so the
-  projected coordinate stays in mm and `tiling_scale` keeps meaning mm). `sample_layer_height()`
-  projects `Vec2f(dot(pos, right), dot(pos, up))`. Single-valued per point, so - like LSCM but unlike
-  blended Triplanar - the fast preview and UV-check overlay precompute it per vertex
-  (`compute_layer_vertex_uvs()`) and drive the shader's `use_vertex_uv` path. Faces angled away from
-  the projector smear; that is inherent to view projection.
-
-  Two companions to this mode:
-  - **Projection frame overlay** (`TextureProjectorFrame`, see below) - a semi-transparent window
-    dragged over the 3D view whose border becomes the projection's edge. Applying it stores an exact
-    **projective** map in `view_project_matrix`, which supersedes the affine `right`/`up` axes above
-    for that layer (`view_project_projective`).
-  - **"Project only on visible"** (`select_visible_faces()`) - repaints the layer with exactly the
-    facets the camera can see, so the projected area matches the viewpoint the projector was captured
-    from. Two tests: a facing test (normal vs. view direction, per triangle - under perspective the
-    view direction varies across the model, so it is taken from the eye to each centroid), then
-    `MeshRaycaster::get_unobscured_idxs()` on the survivors to drop facets hidden behind other
-    geometry, so a concave part's far inner wall is correctly excluded. One ray query per front-facing
-    facet, hence click-driven (on the checkbox and on each "Capture current view"), never per frame.
-    It **replaces** the layer's paint rather than adding to it - "project onto what I can see" would
-    otherwise accumulate every angle the user had ever looked from.
-
-### Manual seams and island cutting
-
-`TextureDisplacementLayer::lscm_seam_edges` - undirected mesh-vertex-index edge pairs the unwrap is
-forced to cut along, on top of the dihedral-angle seams. `segment_into_charts()` takes a set of these
-(translated from mesh -> compacted-patch numbering inside `compute_patch_unwrap()`) and refuses to
-union two triangles across a marked edge whatever their angle. Both the unwrap cache key and the
-gizmo's `UVEditorState` include the seam list, so marking a seam (which leaves the paint mask
-untouched) still forces a re-solve. Like the paint masks, seams are mesh-index-space and so dropped on
-any topology change.
-
-Two ways to write to it:
-- **Mark seam (manual)** - a "Mark seams" click mode (`m_seam_edit_mode`) that suppresses painting. A
-  click raycasts the volume (`m_c->raycaster()->raycasters()[idx]->unproject_on_mesh()`, `idx` = the
-  volume's slot among model-part volumes), finds the facet's edge nearest the hit point, and toggles it.
-  Marked edges render as a red overlay (`render_seam_overlay()`), pulled toward the camera so they read
-  on top. This is the Blender mark-seam workflow.
-- **Cut island (auto)** - `cut_island()` takes the selected chart's triangles (back-mapped from the
-  unwrap via `source_vertex`), finds their 3D bounding box, and marks every edge that straddles the
-  mid-plane perpendicular to the longest axis. The re-unwrap then splits the chart across its narrow
-  waist. Exposed as the UV pane's **Cut** button.
-
-### UV-check overlays (checker / distortion)
-
-`resources/shaders/{110,140}/texture_displacement_uvcheck.{vs,fs}`, one shader with a `mode` uniform,
-drawn over the painted patch (`rebuild_uvcheck_mesh()`/`render_uvcheck_mesh()`, P3N3T2: `normal.x` =
-distortion, `tex_coord` = uv), pulled forward with a polygon offset. **Checker** samples a procedural
-checkerboard at the layer's uv (per-vertex for LSCM/ViewProjected, in-shader triplanar otherwise) -
-squares that stay square mean low distortion. **Distortion** colours each triangle blue->green->red by
-`log2(uv_area / surface_area)` centred on the patch's *median* stretch (so a globally-scaled unwrap
-reads as uniformly ideal and only relative stretch shows), averaged to vertices. A separate **Show mesh
-wireframe** toggle draws the whole volume's triangle edges, rebuilt only when the vertex count changes
-(not per stroke).
-
-### Tiling
-
-`DecodedHeightTexture::sample(uv, tile_enabled, tile_method)`. Two tile methods when enabled
-(Repeat, MirroredRepeat). **When `tile_enabled` is false, sampling outside `[0,1)` returns `0`
-directly** rather than clamping the *coordinate* into range, which would smear the border row/column of
-pixels outward to infinity in every direction (streaky lines radiating out from the painted patch).
-
-### Subdivision - two modes
-
-**Uniform (`subdivide_mesh_uniform()`)** - whole-mesh, 1-to-4 split. Recursive edge-midpoint split with
-a shared per-pass midpoint cache (keyed by sorted vertex-index pair) so triangles sharing an edge get
-the *same* new vertex - capped at `max_iterations` (default 6). Whole-mesh so it never leaves a
-T-junction, at the cost of densifying everywhere. Wired as a "Subdivide steps" slider (**0-5**, 0 =
-no subdivision), Apply snaps back to 0. Drops texture-displacement paint (no remap) via the standard
-`save_painting()`/`set_mesh()`/`restore_painting()` dance; the other four channels are remapped.
-
-**Adaptive (`subdivide_mesh_adaptive()`)** - refine **only the painted area**, by **Rivara longest-edge
-bisection**, which is *conformal by construction*. Only **terminal** edges are ever bisected - an edge
-that is the longest edge of *every* triangle sharing it - which splits both those triangles along one
-shared midpoint at once, so a hanging node is never created. The edge to split for a triangle that wants
-refining is found by **longest-edge propagation (LEPP)**: walk to the longest edge of ever-longer-edged
-neighbours until a terminal one is reached, and bisect that. Edge length strictly increases along the
-path (ties broken by mesh-vertex key, which both sides of an edge compute identically), so the walk
-cannot cycle, and Rivara's result is that repeating it refines the original triangle in a bounded number
-of bisections. The transition triangles it pulls in just outside the painted patch are the graded band
-that makes the size change conformal.
-
-The win: a small decal on a big model no longer quadruples the *whole* model's triangle count.
-
-**Run to completion, worst-first, against a triangle budget.** The refinement loop is not a fixed number
-of sweeps: it holds every triangle that is over its criteria in a max-heap keyed by *how many times over*
-it is, pops the worst, walks its LEPP, bisects, and re-scores. Edge adjacency (`nb[e]`, the triangle
-across each edge) is built **once** and maintained incrementally through each bisection, so the cost
-scales with the refined region rather than with the whole model. `max_triangles` is the only bound;
-stopping on it leaves a perfectly valid, still-conformal mesh that spent its budget on the largest
-errors. A fixed sweep count instead spends itself grading the *coarse surroundings* - whose edges are
-the longest, so they win every terminal-edge contest - and never reaches the painted patch.
-
-**It carries the paint forward**, which is what makes it usable (uniform subdivide drops paint). Because
-the refinement is *driven by* the paint, the remap is trivial: `subdivide_mesh_adaptive()` fills an
-`out_source[new_tri] = input_tri` map (children inherit their parent), and the gizmo rebuilds each
-layer's mask on the new mesh - a new triangle is painted iff its source was fully painted in that
-layer. `collect_paint_region()` derives both:
-- the union refine-region: **exactly** the original triangles the brush touched, read straight off
-  `TriangleSplittingData::triangles_to_split` (`serialize()` records an entry per original triangle that
-  is either split - i.e. partially painted, the patch boundary - or carries a non-default state). No
-  dilation: marking every triangle that shares a *vertex* with the patch drags in a whole fan of huge
-  unpainted neighbours and refines *those* down to the resolution floor, since the height field the
-  detail test samples is not restricted to the painted area. The conformal closure already grades the
-  size change outward on its own.
-- the per-layer fully-painted-triangle sets (a `get_facets_strict(ENFORCER)` sub-triangle with all three
-  *original* vertex indices == a whole, fully-painted original triangle; a partial stroke's sub-triangles
-  always carry a split vertex).
-
-The other four channels ride the normal `restore_painting()` remap.
-
-Both modes share the gizmo's Preview/Apply/Done flow; the **"Only painted area (adaptive)"** checkbox
-picks the mode, and the adaptive preview follows the paint live (`rebuild_preview()` refreshes the
-wireframe while the subdivide preview is open in adaptive mode). The panel shows the previewed triangle
-count.
-
-**Feature-adaptive (follow texture detail).** A sub-mode of adaptive (the **"Follow texture detail"**
-checkbox) that puts triangles where the *displaced surface actually bends*, not evenly. A flat region or
-a linear **ramp** needs no extra vertices (linear interpolation is exact for a ramp); what needs them is
-**curvature** - the *second* derivative, not the gradient. So the extra predicate is a **chord-error**
-test: sample the combined displacement at the triangle's three edge midpoints *and its centroid*
-(sampling the interior is what catches a hill sitting inside a triangle, the blind spot of an edge-only
-test) and take the largest departure from the flat triangle's barycentric interpolation. Refine while
-that exceeds `chord_tolerance_mm` ("Detail (mm)"). Zero chord error on a ramp => untouched; high on a
-hill/ridge/noise => refined until captured. Same conformal machinery, so still crack-free. The
-per-triangle error is cached and recomputed only for the children of a split.
-
-Four knobs bracket it, and all four matter:
-- **"Max edge (mm)"** (`target_edge_length_mm`) is a **baseline that applies in feature mode too**.
-  Without it the chord test aliases: a big triangle over a fine pattern can sample four points that all
-  land at similar heights, report no error, and stall before refinement ever starts. The baseline
-  guarantees a sampling density fine enough for the curvature test to see the texture at all.
-- **"Detail (mm)"** is the chord tolerance above.
-- **"Min edge (mm)"** is a hard floor under both, and is what guarantees termination across a sharp
-  texture *step*, where the error never falls however fine the mesh gets.
-- **"Added triangles (k)"** is the budget, passed as `max_triangles` (the model's own triangle count plus
-  the slider, so the control still means something on an already-dense model).
-
-The height field is `make_combined_displacement_sampler()` - it mirrors `build_texture_displacement()`'s
-per-layer setup (decode, patch centroid, cylinder axis, blend order, "lowest layer folds additively")
-but evaluated per point. Two deliberate simplifications, both erring toward *more* detail (safe -
-over-refinement is never a crack): every sampleable layer is sampled at every point (no per-point paint
-test), and edge-smoothing falloff is ignored. The first is *why* the refine region must not be dilated -
-outside the paint the sampler still reports full relief. **LSCM layers are skipped** (no per-point UV); a
-purely LSCM stack yields a null sampler and the code falls back to the length baseline alone. Per-vertex
-heights are sampled lazily, so a small patch on a huge model never pays for the rest of it.
-
-### Fast preview (GPU-only, no CPU meshing)
-
-`resources/shaders/{110,140}/texture_displacement_shaded.{vs,fs}`, registered as
-`"texture_displacement_shaded"`. Shades the *displaced* surface without moving geometry - active-layer
-only, selected from the View row, and the default when the gizmo opens (`m_use_shaded_preview = true`).
-Vertex format is `GLModel::Geometry::EVertexLayout::P3N3T2`: `normal.x` carries the per-vertex paint
-weight (0/1), `normal.y` flags the UV island currently being dragged, and `tex_coord` carries a
-precomputed texture UV, so it can use `GLModel` normally instead of a hand-rolled VBO/VAO manager.
-
-The mesh is **flat** (vertices not shared between triangles): every corner of a painted triangle gets
-weight 1, every corner of an unpainted one weight 0. A coarse mesh needs that - one painted face of a raw
-cube has no strictly-interior vertex, so per-vertex weighting would either bleed onto the neighbours or
-vanish outright. Duplicating vertices costs no shading quality here because the shader takes its surface
-normal from screen-space derivatives of position, not from a per-vertex normal.
-
-**Both preview meshes work in the patch's vertex space, not the mesh's.** Those agree only until a
-*brush* stroke splits a triangle: `get_facets_strict()` then appends the split vertices, so the patch
-array is longer. `rebuild_shaded_preview_mesh()` and `rebuild_uvcheck_mesh()` therefore index
-`patch.vertices` throughout. The weight buffer is rebuilt at the same cadence as the true-displacement
-preview (stroke-end/slider-release) but from the **live** `TriangleSelector` state, not the flushed model
-facets, so it does not lag by a full model round-trip.
-
-The perturbed normal is the analytic one for a height field `H = +/-depth_mm - h(uv)` displaced along
-`N` over any orthonormal surface tangent pair `T`/`B`:
-
-    N' = normalize(N - (dH/da)-T - (dH/db)-B),   a = dot(p,T), b = dot(p,B)
-
-The two slopes have to be genuine **mm-per-mm** derivatives for the preview's apparent depth to match
-the bake's.
-
-**Two projection paths (`use_vertex_uv` uniform):**
-- **Triplanar (`use_vertex_uv = 0`)** - `uv` and the `T`/`B` axes are both derived in-shader from
-  the dominant normal component, mirroring `project_planar()`/`apply_uv_transform()`, and the slope is
-  formed analytically. `T`/`B` are the projection's axis-aligned pair, exact only when the face is
-  axis-aligned; the shader drops the along-normal component to keep the gradient in the surface. Here
-  one `uv` unit is exactly `tiling_scale` mm, so the `1/tiling_scale` gradient factor is right.
-- **Precomputed UV (`use_vertex_uv = 1`, used for LSCM and ViewProjected)** - `uv` comes per-vertex from
-  the CPU (`compute_layer_vertex_uvs()`, so island placement + tiling/rotation/offset are already folded
-  in), and the perturbed normal is built with **Mikkelsen's method** ("Bump Mapping Unparametrized
-  Surfaces on the GPU"): the surface gradient taken directly from the screen-space derivatives of the
-  *sampled height* and position. **This makes no uv->mm scale assumption**, which is essential, because an
-  LSCM map is **conformal, not isometric**: it is globally area-scaled but the *local* mm-per-uv varies
-  across the chart, so a single global `1/tiling_scale` factor gets the apparent depth wrong. `dFdx(h)`
-  captures the true on-screen rate of change however the chart is stretched. This path is also what makes
-  the fast preview follow the UV editor: move an island and its uv - hence its shading - moves with it
-  (the mesh rebuilds on drag-end, `on_island_edited(finished)` -> `rebuild_preview()` ->
-  `rebuild_shaded_preview_mesh()`). The branch is uniform and the paint weight gates by multiply, so the
-  texture derivatives stay well defined. A triangle straddling a seam has a discontinuous uv -> the
-  `det~0` guard skips it (a localised preview-only artifact, never in the bake).
-
-**Parallax (triplanar path).** Perturbing the shading normal alone welds the pattern to the base surface:
-it does not slide as the camera orbits, and does not get deeper as `depth_mm` grows. The triplanar path
-therefore shades at the point the *displaced* surface would show at this pixel, found by **ray marching**
-(parallax occlusion mapping). A point at ray parameter `s`, i.e. `P + V-s` (`P` the base point, `V` the
-unit direction to the eye), sits at height `s-dot(V,n)` above the undisplaced surface. The displaced
-surface lives in a shell between the extreme values of `amp-(h - midlevel)` - taken from both ends of
-`h  in  [0,1]`, so it holds for an inverted layer and a raised midlevel too, where the surface sits *below*
-the undisplaced one. The march starts at the top of that shell, where the ray is outside the surface by
-construction, and steps inward until the ray height drops below the sampled height. That crossing *is*
-the visible point.
-
-Solving `Q = P + V-(H(Q)/dot(V,n))` by fixed-point iteration instead is geometrically exact but the
-divisor goes to zero edge-on; the sample then lands a large fraction of a tile away and the iteration
-oscillates, which reads as a second, flat copy of the pattern ghosted over the real one. Clamping the
-step to one tile does not help - a tile-sized shift lands on the neighbouring tile, the same pattern
-again. Offset limiting (stepping along the tangential part of `V`) is stable but understates parallax
-enough that the relief still flattens as soon as the camera tilts. Marching has neither problem.
-
-The hit is interpolated between the last two samples, which keeps `PARALLAX_STEPS` (24) affordable, and
-the whole march is skipped when sweeping the shell would move the sample point less than half a texel -
-the head-on case, so the common view pays almost nothing. The 140 variant samples with
-`textureLod(..., 0.0)` inside the loop, since implicit derivatives are undefined in non-uniform control
-flow. Two uniforms exist for this: `midlevel` (parallax needs the real height, not just its derivative)
-and `eye_model_pos` (the camera in the volume's local frame).
-
-Parallax cannot change the model's silhouette or cast shadows; the View row's Normal mode is one click
-away for that. The LSCM path stays plain Mikkelsen normal perturbation - it has no closed-form uv, so there is no cheap
-way to re-project a marched position. One further approximation: the GPU sampler's wrap mode stands in
-for `tile_enabled`/`tile_method`, so with tiling *off* the GPU repeats where the CPU returns 0 outside
-`[0,1)`.
-
-### On-canvas "Adjust Texture" gizmo
-
-A per-active-layer toggle ("Adjust placement") that disables painting and shows a flat pan panel (free
-2D drag on both axes) plus two arrows along the patch's own U/V axes (constrained single-axis drag).
-Anchored to the painted patch's centroid/average-normal (`compute_layer_paint_anchor()`). Hit-testing is
-screen-space distance/point-to-segment, not real 3D ray intersection against the handle geometry - simple
-and good enough at this handle size.
-
-### Projection frame overlay (ViewProjected)
-
-`src/slic3r/GUI/TextureProjectorFrame.hpp/.cpp` - a semi-transparent, resizable `wxFrame` the user
-drags **over the 3D view**, like a slide projector's gate. Whatever the model shows through it is what
-the texture is projected onto, and the window's border becomes the hard edge of the displacement.
-Press **Apply projection frame** and the gizmo reads the window's rectangle and commits it.
-
-The window is deliberately **dumb**: it owns no placement state and reports nothing continuously. Its
-position and size *are* the placement, read on demand at Apply - which is also when the expensive
-visible-facet raycast runs. So dragging it is free and nothing recomputes until asked.
-
-Plain 2D (`wxPaintDC`), not a `wxGLCanvas`: a second GL canvas would have to share the app's one real
-`wxGLContext`. It only ever draws a bitmap and a border.
-
-**The projective mapping (`apply_projection_frame()`)**. The frame defines a **screen-space** rectangle,
-but the bake samples from a **local-space** position, so the two have to be reconciled.
-`view_project_right/up` can only express an *affine* projection - exact under an orthographic camera, but
-wrong under perspective, where the near end of a part projects larger than the far end and no pair of
-axes reproduces that. So the layer instead stores a full projective map (`view_project_matrix`, row-major
-3x4, `uv = (row0-p/row2-p, row1-p/row2-p)`), built like this:
-
-- `K = projection - view - (instance - volume)`, i.e. local -> clip, the same product the renderer uses.
-  Note `Camera::get_projection_matrix()` is typed `Transform3d` (nominally affine) but its perspective
-  form explicitly writes a `(0, 0, -1, 0)` bottom row into the underlying 4x4, so `clip.w = -z_eye` is
-  genuinely carried. The build therefore multiplies **`.matrix()` products** (plain `Matrix4d`), never
-  `Transform3d` products, which would not compose that row correctly.
-- Window coordinates follow `igl::project`'s convention (as `CameraUtils::project` does), with y
-  measured downward. Writing `uv = (win - rect_origin) / rect_size` makes u and v affine in
-  `ndc = clip.xyz / clip.w`; multiplying through by `clip.w` leaves a plain linear combination of `K`'s
-  rows, which is exactly the 3x4 matrix - the perspective divide survives intact.
-- `w > 0` is checked rather than divided blindly. A point behind the projector has `w < 0` and divides
-  to a plausible-looking but **mirrored** uv - the classic way a projected decal reappears on the back
-  of a model. `project_uv_projective()` returns false there and the caller treats it as no height.
-
-The map already includes placement, so `apply_uv_transform()` is **not** applied on top of it - the
-window's own position and size are the placement, and the tiling/rotation/offset sliders would shove
-the result off the frame the user just aligned. A "Clear" button drops back to the affine path where
-those controls mean something again.
-
-Apply also sets `tile_enabled = false`, so `DecodedHeightTexture::sample()` returns 0 outside `[0,1)`
-and the border is a hard edge rather than the first seam of an endless repeat, and repaints the layer
-via `select_visible_faces(&matrix)` - the frame's uv square clips the selection, which both matches the
-paint to the border and keeps the ray queries proportional to the framed area instead of the model.
-
-Owned by the gizmo and **destroyed** (not just hidden) in `on_shutdown()`. Closing it only hides it, so
-reopening keeps it where it was left.
-
-### UV Editor pane
-
-`UVEditorCanvas` (`src/slic3r/GUI/UVEditorCanvas.hpp/.cpp`) - a standalone `wxGLCanvas` rendering the
-flattened LSCM islands (per-island wireframe + outline + fill) over the height texture (background
-quad tiled across the whole unwrap), with mouse pan/zoom. It is wrapped in a **`UVEditorPanel`**
-(same file) that adds a button row (Frame / Snap / Avg scale / Cut / Join / Unjoin) and a status line
-along the bottom naming the current gesture and the shortcuts in play. The *panel* is what is
-registered as a `wxAuiPaneInfo` pane on `Plater`'s `m_aui_mgr`; `Plater::show_uv_editor(bool)`
-shows/hides it (deferred via `CallAfter`, since the gizmo calls it mid-3D-frame), and
-`get_uv_editor_canvas()` returns the inner canvas the gizmo talks to.
-
-Deliberately **shares the app's one real `wxGLContext`** (`wxGetApp().init_glcontext(*this)`, the
-same call `View3D`/`Preview`/`AssembleView` make) rather than creating an independent context like
-`SkipPartCanvas` does elsewhere in this codebase - this is what lets it reuse the already-registered
-`"flat"`/`"flat_texture"` shaders and `GLModel` as-is, instead of needing its own shader
-compilation/VBO management.
-
-**Geometry is uploaded once, in the unwrap's own (raw, mm) coordinates**, one `GLModel` set per island;
-each island is then drawn through its own 2x3 affine (`island_transform_matrix()` composed with the
-layer's tiling/rotation/offset) passed as the `flat` shader's `view_model_matrix`. A drag updates one
-matrix per island and touches no vertex buffer - `on_island_edited(!finished)` calls only
-`set_island_transforms()`, and the full `set_islands()` rebuild happens solely when the unwrap itself
-changes (`unwrap_changed` in `update_uv_editor()`).
-
-**Gestures** (canvas-owned, reported to the gizmo as incremental deltas via `IslandEditFn`): left-drag
-= move, right-drag or **R** = rotate (hold **Shift** to snap to 15° steps - quantised on the
-*cumulative* rotation, not each delta, so it doesn't judder, and accumulated incrementally so it
-survives crossing +/-180°), **S** = scale (R/S modal, click/Enter to confirm, Esc to cancel), wheel =
-zoom about the cursor, middle-drag = pan, **Home**/**F** = frame all. Scale writes
-`TextureIsland::scale`; "Avg scale" (`average_island_scales()`) sets every island to the mean, so
-one island scaled by hand can be matched back to its neighbours' texel density. **Snap** (canvas-owned
-`m_snap_enabled`, toggled from the toolbar) sticks a dragged island's nearest boundary vertex onto a
-neighbouring island's at drag-*end* only - a magnet that re-applies mid-drag is very hard to pull out
-of. Toolbar commands the canvas can't service itself (Avg scale, Cut, Join, Unjoin) are forwarded to the
-gizmo via `CommandFn`; view-only ones (Frame, Snap) it handles directly.

-# Texture Displacement - Feature & Controls Guide
-
-Texture Displacement is a paint-style gizmo that stamps height-map textures onto a model's surface
-and turns them into real relief - engraved or embossed detail - either as a live preview or baked
-into actual mesh geometry. You paint where the texture applies, stack multiple textures as blended
-layers, choose how each is projected onto the surface, and (for the unwrap projection) lay the result
-out by hand in a dedicated 2D **UV Editor** pane.
-
-This document describes every feature and control. For the internal architecture and algorithms, see
-`TEXTURE_DISPLACEMENT.md`.

----
-
-## Quick start
-
-1. Select an object and open the **Texture displacement** gizmo from the left toolbar.
-2. A texture layer is added automatically. Pick a texture from the layer's picker, or import your own.
-3. **Paint** the area you want the texture to affect (or press **Select whole model**).
-4. The relief appears live on the model. Tune **Depth**, **Tile size**, **Rotation**, etc.
-5. If the model is low-poly, use **Subdivide** or **Remesh** so there are enough vertices for detail.
-6. Press **Bake** to convert the preview into real geometry, or leave it as a live preview.
-
-> The tool only ever affects the **painted** area. Everything you don't paint keeps its original
-> surface, and bake blends the relief seamlessly into it.
-
----
-
-## Entering the tool
-
-The gizmo lives on the left gizmo toolbar (icon: `toolbar_texture_displacement.svg`). Its settings
-panel opens beside the toolbar. You can **Dock panel / Undock panel** (top of the panel) to pin it or
-float it freely over the 3D view, and **Close** at the bottom exits the gizmo.
-
-When you first open the tool on a never-textured object it starts with **one texture layer already
-added**, so you can paint straight away.
-
----
-
-## Selection modes
-
-Choose *how* you paint. All three write into the **active layer's** mask.
-
-| Mode | What it does |
-|------|--------------|
-| **Brush** | Free-hand painting with a round brush. Shows a **Brush size** slider and a **Circle / Sphere** choice (circle = surface disc, sphere = 3D ball that also paints around curves). |
-| **Face** | Click a single triangle to paint it. |
-| **Connected area** | Click to flood-fill a region; the **Angle threshold** slider limits how far the fill spreads across changes in surface angle. |
-
-- **Select whole model** - marks the entire model as painted for the active layer, instead of
-  brushing it by hand.
-
----
-
-## View modes
-
-A row of icon buttons labelled **View** controls how the painted area is shown. The first four are a
-radio group; **Wireframe** is an independent toggle. Hover any icon for its tooltip.
-
-| View | Meaning |
-|------|---------|
-| **Normal** | The true displaced geometry - exactly what **Bake** produces. Rebuilt in the background. |
-| **Fast** | A GPU shaded approximation of the *active layer only*. No real geometry movement - quick to update, not exact. Best while tuning or dragging islands. |
-| **Checker** | A test grid painted over the unwrap so you can see stretching (squares stay square where the map isn't distorted). |
-| **Distortion** | A blue->green->red heatmap of how much each area is compressed or stretched in UV space. Needs the **Unwrap (LSCM)** projection. |
-| **Wireframe** | Overlays the mesh edges (white). Independent of the view above; in **Normal** view it sits on the displaced surface. |
-
----
-
-## Auto update
-
-**Auto update** (on by default) rebuilds the true displaced geometry as soon as *anything* changes -
-painting, swapping textures, moving sliders. Turn it off on very heavy models to only rebuild when you
-release a slider (painting still updates on stroke end).
-
----
-
-## Texture layers
-
-You can stack up to **8** texture layers. Each has its own independent paint mask, its own texture,
-and its own parameters, and they combine in slot order like layers in an image editor.
-
-- **Add a layer** - the **+ icon** to the right of the *Texture layers* heading (reuses the tool icon
-  for now).
-- **Remove** - the button on each layer's header row.
-- **Active layer** - click a layer's header (or anywhere in its block) to make it active. The active
-  layer is the one you paint into and the one whose block is tinted. Only one layer is active at a time.
-- **Erase all** - clears the active layer's paint.
-
-Each layer shows a texture **picker** (large preview + name). Open it to choose from the shipped
-library or import your own image (any png/jpg/bmp; it's converted to an 8-bit grayscale height map and
-copied into your user texture folder so app updates can't overwrite it).
-
----
-
-## Per-layer settings
-
-| Control | Range / options | What it does |
-|---------|-----------------|--------------|
-| **Depth (mm)** | 0.01-10 (log) | Maximum displacement along the surface normal. |
-| **Tile size (mm)** | 0.2-200 (log) | Physical size of one texture tile on the surface. |
-| **Rotation** | 0-360° | Rotates the texture on the surface. |
-| **Midlevel** | 0-10 | The grey level that means "don't move". At 0 the texture only pushes outward; raise it and darker texels cut *inward* (one map both embosses and engraves). 0.5 makes mid-grey neutral. |
-| **Smoothing** | 0-1 | Blurs the height texture before it displaces - rounds hard edges and removes speckle without needing a softer source image. |
-| **Edge smoothing** | checkbox + **Edge amount** 0-1 | Fades the relief to flat toward the *edge of the painted area*, so it blends into the surrounding surface. A small amount softens only a thin band at the very edge; the maximum flattens the whole painted face. |
-| **Invert** | checkbox | Flips the height map (peaks become valleys). |
-| **Blend** | Add / Subtract / Multiply / Divide | How this layer combines with the layers **below** it where they overlap. Add/Subtract pile relief on or carve it away; Multiply/Divide scale the relief underneath (a mask). The lowest painted layer is the **Base** and always behaves additively. |
-| **Tile** | checkbox + **Repeat / Mirrored repeat** | When off, the texture is placed once (a decal) instead of repeating. Mirrored repeat flips every other tile to hide seams. |
-| **Projection** | see below | How the texture is mapped onto the painted surface. |
-
-> **Midlevel warning:** cutting inward can fold the surface through itself in sharp concave corners or
-> thin walls. Keep Depth small relative to the feature you're cutting into; the panel warns when a deep
-> inward setting is risky.
-
----
-
-## Projection methods
-
-How the 2D texture is wrapped onto the 3D painted area.
-
-| Method | Best for | Notes |
-|--------|----------|-------|
-| **Triplanar (blended)** | Patches wrapping around edges | Projects from all three axes at once and blends, so there's no seam across a sharp edge. |
-| **Cylindrical** | Round, tube-like selections | Wraps the texture around the patch's own centre/axis. |
-| **Spherical** | Ball-like selections | Longitude/latitude wrap around the patch centre. |
-| **Unwrap (LSCM)** | Flat, controlled layout | A real conformal unwrap. Cuts the area into pieces at sharp edges (see **Seam angle**), flattens each, and lets you lay them out by hand in the **UV Editor**. Unlocks Checker/Distortion, seams, and island editing. |
-| **From view** | Decals / slide-projector look | Projects straight onto the surface from the current camera direction. Use **Capture current view** to re-lay it from wherever you're looking. |
-
-### LSCM-only controls
-
-These appear when a layer uses **Unwrap (LSCM)**:
-
-- **Seam angle** (5-90°) - edges sharper than this are cut so each piece lies flat. Lower cuts more
-  (less stretching, more seams); raise to keep more in one piece. A box's 90° corners are cut by
-  default. *Ignored once you've marked any seam by hand* (your seams then define the pieces).
-- **Connect islands** (on by default) - lays the unwrap out as a **connected net**: pieces that share
-  an edge are unfolded next to each other (a cube becomes a joined net instead of six loose squares).
-  They stay separate islands, so you can still move any of them by hand. Turn off for the classic
-  packed-grid layout.
-- **Open UV editor** - shows the flattened unwrap in a side pane (see below). Opens *only* when you
-  turn this on - it never pops up on its own.
-- **Mark seams** / **Path** / **Clear seams** - see [Seams](#seams).
-- An **Unwrap: N islands, F faces, V verts** read-out tells you what the unwrap actually produced.
-
----
-
-## The UV Editor
-
-A dockable 2D pane (enable **Open UV editor** on an LSCM layer) showing the flattened unwrap over the
-height texture. Islands are the flattened pieces; you can rearrange them freely - nothing re-packs them
-behind your back. Moving an island updates the model **live** (in Fast view it tracks the cursor
-smoothly, via a shader uniform - no rebuild until you release).
-
-### Navigation
-
-| Action | Control |
-|--------|---------|
-| Pan | Middle-drag |
-| Zoom | Mouse wheel (zooms about the cursor) |
-| Frame everything | **Home** or **F**, or the **Frame** toolbar button |
-
-### Editing an island
-
-| Action | Control |
-|--------|---------|
-| Select | Left-click an island |
-| Move | Left-drag |
-| Rotate | Right-drag, or press **R** then move the mouse (click/Enter to confirm, Esc to cancel) |
-| Rotate snapped | Hold **Shift** while rotating - snaps to **global** 15° marks (0/15/30...). A protractor dial with tick marks and the current angle is shown. |
-| Scale | Press **S** then move the mouse (click/Enter to confirm, Esc to cancel) |
-| Undo / Redo | **Ctrl+Z** / **Ctrl+Shift+Z** or **Ctrl+Y** |
-
-The **selected** island gets a bold light-green outline and a brighter wireframe; unselected islands
-are a translucent light-green wash. The texture underneath repeats exactly as it will when baked.
-A **status line** along the bottom always names the current gesture and the shortcuts in play.
-
-### Toolbar
-
-| Button | Action |
-|--------|--------|
-| **Frame** | Frame all islands (same as Home). |
-| **Snap** | Toggle magnetic snapping - a dragged island sticks its boundary to a neighbour's when they come close. |
-| **Avg scale** | Give every island the same texel density (Blender's "Average Islands Scale"). |
-| **Cut** | Split the selected island across its long axis (useful for very long islands). |
-| **Join** | Unfold the selected island onto its nearest neighbour along their shared edge - keeps both as separate islands with their own borders. |
-| **Unjoin** | Send the selected island back to its own packed position. |
-
-> **Checker / Distortion in the UV editor:** selecting those View modes also colours the UV pane - a
-> checker background, or a per-island distortion heatmap - so you can judge stretch in 2D as well as
-> on the model.
-
----
-
-## Seams
-
-Seams are edges the unwrap is forced to cut along, on top of whatever the Seam angle cuts - the
-Blender "mark seam" workflow. They let you control exactly where the unwrap splits.
-
-Enable **Mark seams** on an active LSCM layer, then:
-
-- **Click an edge** on the model to mark it (it turns **red**); click a red edge again to unmark it.
-  The edge under the cursor is highlighted **yellow** so you can see what a click will toggle.
-- **Path mode** (the **Path** checkbox) - for dense meshes where clicking each edge is tedious: click a
-  start point, then an end point, and the whole **shortest path** between them is seamed at once. It
-  chains (each click extends from the last point); the start vertex is shown in **green**.
-- **Ctrl+drag** rotates/pans the camera while in seam mode.
-- **Clear seams** removes them all.
-
-Once any seam is marked, the automatic Seam-angle cutting is disabled so *your* seams define the
-islands - pieces you leave un-seamed merge together.
-
----
-
-## Adjust placement (on-model)
-
-**Adjust placement** (on an active layer) lets you position the texture by dragging a handle on the
-model instead of nudging the Rotation/offset numbers. The handle is a flat panel in the patch's
-tangent plane (drag anywhere on it to move freely) plus U/V arrows for single-axis nudges. It's
-anchored to the painted patch, so paint something first.
-
----
-
-## Preparing the mesh: Subdivide & Remesh
-
-Displacement can only move vertices that exist, so a coarse model needs more of them first.
-
-### Subdivide
-
-Splits every triangle into four, **1-5 times** (each step roughly quadruples the triangle count).
-
-- **Subdivide steps** (1-5) - how many times to split.
-- **Preview subdivision** - shows the result as a **cyan wireframe** without changing the model.
-- **Apply** - commits the subdivision to the geometry.
-- **Done** - ends the preview and leaves the model as it is.
-
-### Remesh
-
-Rebuilds the whole model with triangles close to a target edge length - evens out a mesh with wildly
-varying triangle sizes (CGAL isotropic remeshing).
-
-- **Target edge (mm)** - desired triangle edge length (seeded to the model's current average).
-- **Remesh** - splits the big triangles and merges the small ones to that size.
-
-> Both Subdivide-Apply and Remesh **replace the geometry** and clear any *not-yet-baked* paint on it
-> (already-baked relief is kept). If you had the mesh **Wireframe** on before, it stays on afterward.
-
----
-
-## Baking & resetting
-
-- **Bake** - converts the current preview into real, permanent mesh geometry, restricted to the
-  painted area. Runs in the background; the button shows *Baking...* while it works.
-- **Erase all** - clears the active layer's paint.
-
-Baking is the exact same algorithm as the **Normal** preview, so what you see is what you get.
-
----
-
-## Controls reference

-
----
-
-## Tips & limitations
-
-- **Paint first, then bake.** The preview is free to explore; only Bake changes the real mesh.
-- **Not enough detail?** Subdivide or Remesh before painting fine textures.
-- **Inward cuts** (high Midlevel + big Depth) can self-intersect on thin walls or sharp concave
-  corners - keep Depth modest there.
-- **Fast vs Normal:** Fast preview only shades the relief and shows only the active layer; use it for quick
-  tuning and smooth UV dragging, but trust **Normal**/**Bake** for the exact result.
-- **Topology changes drop unbaked paint.** Subdivide-Apply, Remesh, and Simplify replace the mesh, and
-  texture-displacement paint isn't remapped across that change (already-baked relief is unaffected).
-- **Island placements** are tied to the current unwrap. Re-painting or changing the Seam angle can
-  re-segment the charts and renumber them, so a re-unwrap re-lays the connected net and discards
-  hand placements made before it.
-- **Connect islands** is on by default; turn it off (per layer) for the classic packed-grid layout, or
-  if an unfold looks wrong on an unusual mesh.

-# Deferred Page Construction: High Level Design
-
-## Why it exists
-
-The main window is a notebook of tabs, and only one of them is on screen when the first
-frame appears. Others are opened later in the session, some never, and some only exist
-for certain printers. Building every tab before the first frame makes each startup pay for
-tabs the user may never open.
-
-This subsystem builds a tab the first time it is shown, and builds the rest in small units
-while the user is idle after startup. Startup pays only for what the first frame shows,
-the other tabs are usually ready before anyone opens them, and a click that lands in the
-middle of the idle build waits for one unit at most. Work that is not a tab, such as a
-dialog or the 3D view's GL resources, uses the same machinery.
-
-## The parts
-
-The parts are independent. A holder can hold anything a factory makes, a placeholder page
-is a holder with a widget, a staged object can live outside a holder, and the scheduler
-knows none of them; it runs tasks, which the main window makes from the holders.
-
-### The holder: `Lazy<T>`
-
-A holder keeps one object and the factory that makes it. The rest of the app reads the
-object if it exists, makes sure it exists now when about to show or navigate to it, or runs
-something once it exists. A type with one instance in the app gets these as statics
-through `LazyInstance<T>`, so callers need no reference to the main window, and all of them
-are harmless while no holder exists.
-
-The holder guarantees that callers see the object only once it is completely built. A
-build cannot re-enter itself, so a nested request finds nothing yet, and a factory that
-returns null or a unit that throws leaves the holder and the scheduler able to carry on.
-The holder does not own the object; its wx parent does, as for any window. The holder has
-no wx dependency and is unit-tested.
-
-### The placeholder page: `LazyPage<Panel>`
-
-The notebook needs a page object for a tab to exist and for tabs to be inserted and
-removed by pointer, and the placeholder is that object. It builds the real panel inside
-itself the first time it is shown and forwards showing and hiding afterwards, so a panel's
-own show handling stays its activation hook. Nothing builds while the main window is
-hidden; the window's first show builds the start page. A page that is out of the book is
-not prebuilt. A panel built while its page is hidden stays hidden, and gets the theming
-the window applied before the panel existed.
-
-### Staged construction: `StagedBuild`
-
-A constructor too big to be one unit builds a skeleton and queues the rest as steps, which
-run one per unit. A child panel's steps can be forwarded to its parent, and the parent is
-complete only once the child is. Nothing may use what a step builds before the last step
-has run, so staged panels follow these constraints:
-
-- members created in steps start out null, so a partly built panel can be destroyed;
-- timers, event handlers and destructors that touch step content check that the panel is
-  complete first;
-- nothing takes focus while off screen, since a unit may run while the user is typing
-  elsewhere;
-- a widget added by a step keeps its place in the sizer through an empty slot the skeleton
-  creates.
-
-### The scheduler: `IdleScheduler` and `PrebuildQueue`
-
-The queue holds tasks in order, and a slice runs units of the first pending task until
-the task finishes, the time budget is spent, or input arrives. It has no wx dependency and
-is unit-tested with a fake clock. A task whose work goes away, such as a tab removed from
-the book, is skipped, and becomes pending again if the work comes back.
-
-A slice runs only once the user has been idle for a short quiet time, and each slice is its
-own timer message, so paint, timers and input queued in between are handled before the
-next slice. Posting slices as pending events would not do that, because wx drains every
-pending event before the next native message. On GTK a timer that is always due starves
-the lower-priority sources that repaint and deliver posted events, so slices are a few
-milliseconds apart. On Windows a slice also waits while the native queue holds input,
-not counting mouse moves, which Windows synthesizes whenever a window appears under the
-cursor. A slice never runs inside a `wxYield()`, where it would build pages in the middle of
-the code that yielded. A unit cannot be interrupted, so the largest unit bounds how long a
-click can wait.
-When nothing is pending the timer stops and the subsystem costs nothing.
-
-The main window owns the scheduler because it owns what the tasks build, and clearing the
-queue with the window keeps a task from outliving its object. Each owner provides its own
-tasks, such as a tab, a dialog, the Prepare tab's settings page one option group at a
-time, the Prepare page's layout at the size the book gives its pages, or the 3D view's GL
-resources.
-
-### The 3D view's GL resources
-
-OpenGL is loaded on the Prepare tab's canvas. When the start page is not Prepare, loading
-it is an idle task that makes the context current on the hidden canvas, so the start page
-paints first and Prepare never appears. Loading it on a shown canvas under `Freeze()` holds
-back the start page's paint, and on GTK `Freeze()` cannot hide the canvas, which is a
-native child window or a Wayland subsurface drawn outside GTK. A hidden Windows child
-window keeps its device context, macOS attaches the context to a hidden view, and GTK
-creates the canvas's surface when the widget is realized, so on GTK the task realizes the
-canvas first. If the context cannot be made current, the canvas's first render loads the
-resources.
-
-## Rules
-
-**Before the first frame.** Only the start page and the Prepare tab's plater are built
-before the first frame. Everything else goes through a holder.
-
-**Reaching a lazy object.** Callers use the type's statics. Reading it if built is for
-things the object can live without, such as a rescale, a color change or a status refresh.
-Making sure it exists is for navigating to it or showing it. Running something once it is
-built is for state it would not fetch for itself on construction. A panel that pulls its
-state when constructed only ever needs to be read if built.
-
-**Unit size.** A unit should fit in one slice on a fast machine. A constructor over that is
-staged, and a single widget over it is accepted unless the widget itself can be split.
-
-**Order.** Tasks run cheapest and most likely to be opened first. Each holder's order is
-given where it is created, with gaps so a new task fits between its neighbors. A negative
-order is never prebuilt, for something few sessions open that costs more to build unasked
-than it saves.
-
-## Adopting it
-
-A lazy tab needs a panel type deriving from `LazyInstance`, a placeholder page the main

-# Design tab — High Level Design
-
-## Purpose and scope
-
-The Design tab is a parametric CAD environment inside the slicer: sketch, constrain, build
-solid features, commit the result to the plate. It exists because the alternative is a round
-trip through an external CAD application, and that round trip discards design intent at both
-ends — a part edited after slicing comes back as a mesh rather than as the feature history
-that produced it. Keeping the model in the project means a dimension can be changed after the
-part has been sliced, with the nozzle diameter, the build volume and the material already
-known.
-
-Its coupling to the rest of the application is deliberately narrow. It adds no stage to the
-slicing pipeline and touches neither the preset system nor `Tab`. It reaches the rest of Orca
-in two places: **Commit to Plate**, which hands finished solids to Prepare as ordinary model
-objects, and one optional 3MF archive entry that carries the recipe. Everything else is
-contained in `src/libslic3r/CAD/` and `src/slic3r/GUI/CAD/`.
-
-The user-facing manual lives in the wiki
-([Design Tab](https://www.orcaslicer.com/wiki/design_tab)), not here. This document covers the
-parts of the design that the code does not make evident.
-
-## The model is a recipe
-
-`CadDocument` holds an ordered list of `CadFeature` and nothing else that matters. Bodies,
-meshes and display geometry are **derived**: `recompute()` replays the feature list from the
-start and rebuilds them. Editing a dimension set twenty features ago is therefore an ordinary
-edit — everything downstream is rebuilt by the same replay that built it the first time.
-
-Two consequences follow from deriving rather than storing:
-
-- **Undo is a snapshot of `features` alone.** The caller calls `checkpoint()` before the
-  mutations that make up one user action; undo restores that snapshot and recomputes. Because
-  everything else is derived, one checkpoint is exactly one `Ctrl+Z` step and the restored
-  state is exact rather than approximately reconstructed. The tab keeps this stack itself; it
-  is not Orca's project snapshot system, which operates on `Model` objects the Design tab does
-  not own until Commit.
-- **Face and edge ids are session-scoped.** They are indices into `TopExp::MapShapes`, so a
-  rebuild invalidates every one of them. `CadDocument::topo_generation` is bumped on every
-  rebuild so a holder of an id can discover that it is stale instead of silently addressing a
-  different edge. The counter is deliberately not serialized: an id means nothing outside the
-  run that produced it.
-
-## Geometry kernel and dependency surface
-
-The kernel is OCCT, which OrcaSlicer **already** links — `Format/STEP.cpp`, `Format/svg.cpp`
-and `Shape/TextShape.cpp` use it upstream. The Design tab adds no third-party dependency; it
-widens the existing OCCT build by one module flag in `deps/OCCT/OCCT.cmake`:
-
-```cmake
--DBUILD_MODULE_ModelingAlgorithms=${SLIC3R_CAD}
-```
-
-Most of that module's twelve toolkits were already being built, because `DataExchange` — the
-STEP path upstream ships — depends on them. The delta is `TKFillet` (used through
-`BRepFilletAPI`), `TKOffset` (`BRepOffsetAPI`) and `TKFeat`, which nothing here references but
-which the module flag builds anyway, because OCCT's module flags are all-or-nothing. On macOS
-and Linux OCCT links statically, so an unreferenced toolkit costs build time and no shipped
-bytes; on Windows OCCT builds shared, so the cost there is real DLL bytes. That Windows figure
-has not been measured, and `OCCT.cmake` says so rather than carrying a number that was derived
-from an incomplete toolkit list.
-
-On Windows the packaging step asserts that every linked OCCT toolkit has a shipped DLL and
-fails the configure with the name of any that is missing, because the alternative failure — a
-deps prefix built with a different `SLIC3R_CAD` setting than the app — otherwise surfaces as a
-missing DLL at first launch.
-
-## The sketch constraint solver
-
-`src/libslic3r/slvs/` is a vendored subset of SolveSpace's `libslvs`: self-contained, no
-external dependencies, **GPL-3.0**, with its `LICENSE` preserved verbatim in the directory.
-`SketchSolver.cpp` is its only consumer and drives every sketch constraint in the tab.
-
-OrcaSlicer is AGPL-3.0. GPLv3 §13 permits combining a GPLv3 work with an AGPLv3 work and
-AGPLv3 §13 grants the converse, so the combined work is distributable under AGPL-3.0 with the
-solver's GPLv3 terms preserved. The solver is vendored rather than fetched as a dependency
-because it is a pinned subset with no build system of its own; the cost of that choice is
-upstream-sync burden, paid deliberately to keep `deps/` unchanged.
-
-## The SLIC3R_CAD gate
-
-`SLIC3R_CAD` (default ON) compiles the tab and selects the OCCT module flag above. With it OFF
-the tab is not built and the deps prefix matches upstream exactly. The gate is cheap because
-the hooks the Design tab adds to shared GUI code — chiefly the `m_design_sketch_tool` member
-and the render, mouse and key hooks in `GLCanvas3D` — are null-guarded on the path they extend,
-so removing the tab removes behaviour rather than requiring the host code to be rewritten.
-
-The flag has to agree between the dependencies and the application; that is what the DLL
-assertion above is checking.
-
-## Project persistence
-
-A project stores the recipe as one optional archive entry, `Metadata/orca_cad.bin`, backed by
-a single `std::string cad_recipe` on `Model`. The entry is written only when the string is
-non-empty, and readers that do not know it ignore it, so projects that contain no CAD model are
-byte-identical to what upstream would have written and older readers are unaffected.
-
-The blob is a cereal binary archive whose layout is the field order of `CadFeature`'s
-save/load. That makes the format the one irreversible decision in the subsystem, and the rules
-that keep it survivable are:
-
-- **Append only, never reorder.** Enums serialize positionally as their underlying integer, so
-  inserting a value in the middle of `SketchConstraintType` or `CadFeatureType` reinterprets
-  every constraint in every saved project. New fields go at the end.
-- **Features are length-framed.** Since v5 each feature is a length-prefixed, self-contained
-  cereal stream, so a reader can skip a feature written by a newer build and stop cleanly on an
-  older one. This is what makes appending a field a non-breaking change from here on. v4 and
-  earlier still open through the pre-framing flat path; v1 is deliberately not loadable and has
-  no migration path.
-- **A newer stamp is refused, not guessed at.** `deserialize_recipe` rejects a blob whose
-  version exceeds `ORCA_CAD_RECIPE_VERSION` with a message naming both versions.
-- **The rules are held by fixtures, not by discipline.** `tests/data/cad_recipe_v{3,4,5}.bin`
-  are checked-in blobs from the builds that wrote them, and the tests that load them fail if a
-  field is reordered — which the in-memory round-trip test cannot detect. A regeneration test
-  (`[.regen]`, not run by default) produces a fresh fixture when a new version is stamped.
-
-`Import` features embed the imported solid as an OCCT BRep string inside the recipe rather than
-referencing the source file, so a project opens without the STEP or mesh it was built from.
-The cost is that saved projects are coupled to an OCCT BRep revision.
-
-## The interaction contract
-
-Three inputs carry the whole modelling loop — left click, right click and `Esc` — and the
-contract between them is stated in code rather than spread across handlers.
-
-`DesignInteraction.hpp` defines a four-level LIFO stack whose enum value *is* the depth, so
-"which level does this press belong to" is a comparison:
-
-| Level | Holds | One `Esc` press |
-| --- | --- | --- |
-| `Transient` | a value field or a popup menu | closes it; the tool stays armed |
-| `Gesture` | an uncommitted delta — an entity being drawn, a body being dragged | reverts it; committed work is untouched |
-| `Tool` | a feature card, an armed sketch tool, a constrain session | exits it; drawn entities survive |
-| `Idle` | nothing transient | clears the selection; leaves a sketch session only if it is empty |
-
-`cad_escape_level()` is a `constexpr` free function over a POD of four booleans rather than a
-method on the panel, so the ordering that is the entire contract is checkable without a window,
-a GL context or an event loop — five `static_assert`s in the header do exactly that at compile
-time.
-
-**The strict invariant: no level of `Esc` deletes a feature, discards a sketch that holds
-geometry, or rolls history back.** Destroying work needs a gesture that says so — `Del` on an
-explicit selection, the sketch ribbon's Cancel, which asks first, or `Ctrl+Z`. A sketch
-*session* is deliberately not a `Tool` level; it is the environment the `Idle` level lives in,
-which makes the destructive path unrepresentable rather than merely unlikely.
-
-Right-click is read at button-up against two independent budgets — 3 px of drift and 200 ms —
-because drift alone still popped a menu at the end of a slow, careful orbit. The raycast uses
-the press position, not the release. An armed sketch tool that already consumed the right
-button (to terminate a chain, say) declines to also open a menu, through a read-and-clear flag.
-Past either budget the event is navigation, and navigation does not transition the state
-machine.
-
-Entering a sketch changes three things at once so the mode is legible: a banner above the
-canvas (a sibling of the canvas, not a child over it — on GTK a child window over a
-`wxGLCanvas` is a native window and does not reliably stack over GL), the printer bed muted so
-a plate grid is never read as a sketch grid, and `N` to look normal to the plane. Code that
-changes any of the three belongs with a change to this section.
-
-## The offer is generated, not hand-written
-
-Right-clicking geometry opens the *offer*: eight families in a fixed order, each verb at a
-permanent row index, verbs that do not apply shown disabled **in place with their reason**
-rather than removed. The invariant is that a verb's row index is identical in every selection
-where it appears and that adding a verb never moves an existing one — the hand learns the
-position, so the menu is never re-sorted, compacted or adaptively ordered.
-
-An invariant across 92 verbs and 20 selection kinds does not survive by review, so the map
-exists once, as data: `scripts/CAD/tool_atlas.json` carries every verb with its row, key, icon,
-accepted selections, preconditions and refusal string, and `scripts/CAD/gen_offer_table.py`
-emits `src/slic3r/GUI/CAD/DesignOffer.hpp` from it. The header is checked in and never
-hand-edited; `scripts/CAD/run-all-checks.sh` runs the generator with `--check` as its first
-rung, which is what makes "GENERATED — DO NOT EDIT" a fact rather than a request. The generator
-also refuses an atlas with a duplicate verb id, since `mcp_run_verb` resolves a verb by id and
-would make the second one unreachable.
-
-The atlas and its generator sit in `scripts/CAD/` rather than in `docs/`: they are build inputs
-for a checked-in header, not documentation.
-
-## Automation surface
-
-`McpControl` exposes the document over JSON-RPC when `ORCA_CAD_MCP` is set in the environment,
-with `tools/orca_cad_mcp_bridge.py` as the client side. It describes the scene, queries
-topology, measures, and runs the same verbs the offer does — it re-implements nothing, so a
-scripted action and a clicked one cannot diverge. It is off unless the variable is set.
-
-## Where the code lives
-
-| Path | Role |
-| --- | --- |
-| `src/libslic3r/CAD/CadDocument.*` | the feature recipe, its replay, undo and serialization |
-| `src/libslic3r/CAD/GeometryEngine.*` | OCCT wrapper — faces, edges, booleans, healing |
-| `src/libslic3r/CAD/SketchEngine.*` | profile → wire → solid |
-| `src/libslic3r/CAD/SketchSolver.*` | constraint solving, over the vendored solver |
-| `src/libslic3r/slvs/` | vendored 2D constraint solver (GPLv3) |
-| `src/slic3r/GUI/CAD/DesignPanel.*` | the tab: toolbar, feature cards, tree, key maps |
-| `src/slic3r/GUI/CAD/DesignCanvas.*` | viewport integration |
-| `src/slic3r/GUI/CAD/DesignSketchTool.*` | in-canvas sketching |
-| `src/slic3r/GUI/CAD/DesignInteraction.hpp` | the Esc level contract |
-| `src/slic3r/GUI/CAD/DesignOffer.hpp` | generated offer table |
-| `scripts/CAD/tool_atlas.json` | source of truth for the offer |
-
-## Verification
-
-The kernel is covered by Catch2 suites in `tests/libslic3r/` (`test_caddocument`,
-`test_sketchconstraints`, `test_sketchedit`, `test_sketchimport`, `test_sketchinference`,
-`test_sketchprofile`, `test_slvs_constraints`), which need no display;
-`scripts/CAD/run-kernel-tests.sh` builds only `libslic3r_tests` and runs them headless.
-
-The GUI half is not covered by CI, which has no OpenGL canvas or synthetic input: the ladders
-in `scripts/CAD/` drive a running application in a local rig instead, and
-`scripts/CAD/run-all-checks.sh` is the gate that runs all of them. A green kernel run says
-nothing about the viewport, so the two are reported separately rather than as one number.

-# Keyboard Shortcuts
-
-## Why it exists
-
-Key events arrive in several windows (the main frame's char hook, the 3D canvases, the
-gizmo manager and the object list), and the same keys are shown again in menu labels,
-toolbar tooltips, gizmo names and the shortcuts dialog. The registry is the one table all
-of them read. Each binding is defined once; dispatchers look key events up there, labels
-are derived from it, and a change the user makes updates all of them.
-
-## Data model
-
-`KeyChord` (`src/slic3r/GUI/KeyChord.hpp`) is one key press: the key code as
-`wxEVT_KEY_DOWN` reports it, plus the `wxMOD_*` modifiers held with it. It has two
-text forms. The canonical one (`Ctrl+Shift+S`) is platform-neutral and doubles as the wx
-accelerator string and the config format. The display one uses translated modifier
-names and the command and option glyphs on macOS. `KeyChord::from_event()` turns any wx
-key event into the same key code and modifiers, so a chord recorded in the dialog is
-equal to the chord a dispatcher builds from the key press.
-
-`Shortcut` is the enum of every user-facing binding. `shortcut_table` in
-`src/slic3r/GUI/Shortcuts.cpp` gives each one a config key, a description, a context
-mask, a default chord, a `repeatable` flag and a `modifier_variants` flag, in the order
-the dialog lists them; a `static_assert` keeps the table and the enum in step.
-
-`ShortcutRegistry` overlays the user's overrides on the defaults and keeps a
-chord-to-shortcut index for lookups. It reads and writes the `shortcuts` section of
-`AppConfig`. Only overrides are stored, so a default can change between releases
-without touching anyone's config; `none` records a shortcut the user unbound.
-
-## Contexts
-
-A key press is looked up in the context of the window that received it.
-
-| Context      | Dispatcher                                                | Examples                      |
-|--------------|-----------------------------------------------------------|-------------------------------|
-| `Global`     | `MainFrame`'s `wxEVT_CHAR_HOOK`, before any child sees it | New project, camera views     |
-| `Plater`     | `GLCanvas3D` of the 3D and assembly views                 | Arrange, gizmo activation     |
-| `Preview`    | `GLCanvas3D` of the G-code preview                        | One-layer mode, jump to layer |
-| `ObjectList` | the object list                                           | Copy, delete, auto drop       |
-| `Painting`   | `GLGizmosManager` while a painting gizmo is open          | Circle, sphere, fill tools    |
-
-A shortcut can belong to several contexts, which is how copy and paste are a single
-binding for the canvas and the object list. Two shortcuts can share a chord when their
-contexts do not overlap; `C` is the cut gizmo in the 3D view, the G-code window in the
-preview and the circle tool while painting. A Global chord is dispatched before every
-other context, so the dialog treats it as conflicting with all of them.
-
-A Global shortcut has to include Ctrl or Alt or use a key that types nothing, since a
-bare printable key in the frame hook would swallow that character in every text field.
-The dialog refuses such chords and `ShortcutRegistry::load()` drops them from the config.
-Space counts as typing. The speed dial's default is the one bare Space, and
-`MainFrame` leaves it to a focused control that uses Space itself (text fields, buttons,
-combo boxes), so it opens the dial from the canvases and the tab strip only.
-
-## Which event a chord matches
-
-Letters, digits and special keys match on `wxEVT_KEY_DOWN`. Its key codes do not depend
-on the keyboard layout: the key labelled `Q` on an AZERTY keyboard and the key in the
-same position under a Cyrillic layout both report `Q`. Numpad keys fold onto their main
-keyboard equivalents, so `Ctrl+1` and `Ctrl+Numpad 1` are one binding.
-
-Punctuation matches on `wxEVT_CHAR`, because only the char event knows which character
-a key produced under the active layout. `+` is Shift and `=` on a US keyboard and a key
-of its own on a German one, and the binding means the character in both cases. The
-canvas looks a key up on key-down first and, when nothing matched, once more on the char
-event, for punctuation chords only. The dialog records chords the same way: a printable
-non-alphanumeric key pressed with nothing but Shift is taken from the char event that
-follows.
-
-wxGTK does not report key auto-repeat, so the canvases share one record of the keys
-seen going down and swallow the repeats of every shortcut not marked `repeatable`. Zoom
-and undo repeat, for example; a toggle such as Tab does not. The record is shared because
-a shortcut can move the focus to another canvas while its key is still held; a key
-released while no canvas had the focus is dropped on the next press.
-
-A few shortcuts have `modifier_variants`: Shift or Ctrl added to their binding selects a
-step of the same action (1 mm and camera-space moves of the selection, five-step slider
-moves). Only a binding without Shift or Ctrl of its own has steps, so no two bindings
-share one. `ShortcutRegistry::match()` looks the exact chord up first and only then, when
-nothing is bound to it, looks for such a shortcut whose binding is the chord minus those
-modifiers, reporting which were added; a binding on Ctrl+Shift+key therefore wins over
-the combined step. The Shift and Ctrl steps themselves are reserved. `step_owner()` names
-the shortcut they belong to, the capture dialog refuses to assign them, and
-`conflicts()` reports exact chords only. A binding made before its key became a stepping
-key keeps its chord and shadows that one step. A move or rotation of the selection
-started from the keyboard runs until the key that started it is released, or the
-canvas loses focus, so a held key is one undo step.
-
-## Labels
-
-Menu labels, toolbar tooltips, gizmo names, the context menu and the shortcuts dialog
-read the registry, so a rebinding shows up in all of them. Each tracked menu item keeps
-its base label; `MainFrame::update_shortcut_labels()` appends the current binding
-again after an edit, which also installs the new wx accelerator.
-
-A chord that is unsafe as a menu accelerator, meaning a bare printable key, is appended
-to the label as plain text so the menu cannot take it away from text fields. The macOS
-edit menu shows its clipboard and undo entries that way, because a system-menu key
-equivalent for Cmd+C would run instead of the text field's own copy.
-
-On macOS the object list receives no key events at all, so its bindings are installed as
-a `wxAcceleratorTable`, regenerated from the registry after each edit.
-
-## Editing
-
-The shortcuts dialog has a page per context, each opening with a line that says when its
-keys apply. A page lists the shortcuts under the headings of `section_table`, with the
-fixed keys that cannot change (mouse buttons, the step modifiers, Esc, the digit keys
-that pick a filament) sorted into the same sections. The mouse drag rows describe the
-camera actions chosen in Preferences; their button opens Preferences > Control with that
-option scrolled into view and focused, instead of editing a key.
-Editing a row opens a capture dialog that records the next chord, names the shortcuts it
-would take the chord from, and on confirmation unbinds those and binds this one.
-Resetting a row asks the same question when its default is now held by another
-shortcut, so a reset cannot leave two shortcuts on one chord. Each change is written to
-the config at once and pushed to the menus, tooltips and accelerator tables through
-`GUI_App::on_shortcuts_changed()`. The dialog opens from the Help menu and Preferences >
-Control on the Global page, and from the `?` key on the page of the view that received it.
-
-## Adding a shortcut
-
-1. Add the enum value to `Shortcut` and its row to `shortcut_table`, in the position
-   the dialog should list it; the row's section heading is the `section_table` entry
-   above it, so a new section needs an entry there too. Pick a default that does not
-   collide inside its contexts; the `[Shortcuts]` tests check every default against the
-   others.
-2. Handle it in the dispatcher of its context: `MainFrame::handle_global_shortcut`,
-   `GLCanvas3D::handle_shortcut`, `ObjectList::dispatch_shortcut`, or a gizmo's
-   `on_tool_shortcut`. A gizmo that opens on a key sets `m_shortcut` in its constructor.
-3. Where the UI shows the key, ask the registry (`display()` for tooltips,
-   `accelerator()` for menu labels); no label holds a literal key name.

-# Multiline infill — High Level Design
-
-## Purpose and scope
-
-`fill_multiline` prints every sparse infill wall as N adjacent lines instead of
-one, so a wall is `d1 = N * spacing` thick. Only internal sparse infill uses it.
-Each pattern first builds its single-line centerlines at N times the usual line
-spacing (so the density holds), and `multiline_fill()` then replaces each
-centerline by the lines of that wall: the centerline itself when N is odd, and
-closed outlines around it at every `spacing` out to `d1 / 2`. The outlines are
-clipped to the fill region contracted by half a line width, then connected like
-any other infill.
-
-Outlines of centerlines that cross each other overlap at every crossing, which
-over-extrudes the wall intersections. The line-crossing patterns Grid,
-Triangles, Tri-hexagon and Cubic therefore build centerlines that never cross
-(`FillRectilinear::fill_surface_trapezoidal()`), and so do Adaptive Cubic and
-Support Cubic (`FillAdaptive`); the other patterns outline their usual
-centerlines.
-
-## Non-crossing centerlines
-
-The crossing lines are resolved into x-monotone paths, the levels of the line
-arrangement: walking along x, the k-th path is always the k-th line from the
-bottom. At every crossing, the two paths bounce off each other instead of
-passing through. Adjacent paths meet only at crossings, so their outlines touch
-there and nowhere overlap.
-
-Where two paths meet, each is cut short by a line perpendicular to the bisector
-of its bend, `d1 / 2` from the crossing. The two cut segments are parallel and
-`d1` apart, so the outermost lines of the two walls sit exactly `spacing` apart,
-like the lines inside a wall. Where three lines meet at one point, the middle
-path runs straight through and the outer two are cut `d1` from it.
-
-Each pattern builds its rows along x in a rotated frame. Grid lines run at ±45°
-there, and its rows are trapezoid waves that transpose on alternate layers. The three families of Triangles, Tri-hexagon and
-Cubic run at 0°, 60° and 120°. Those rows rotate by 120° every layer about a
-3-fold center of the arrangement, so each family takes every role in turn.
-The pattern is phased on fixed positions, so it lines up across layers and
-across the regions of one layer. Rounding the corners with
-`sparse_infill_smooth_factor` happens before `multiline_fill()`.
-
-Each region builds only the rows over its bounding box in that frame, and
-outlines only the centerlines within `d1 / 2` of it, the ones whose outlines
-reach it. Every row is monotone along its direction, so each outline is started
-on the cap at the first end of its centerline, outside the region, and clipping
-to the region cuts it only where it crosses the boundary.
-
-## Cubic
-
-Single-line Cubic draws the three families at the same spacing `h` and shifts
-them with z: by `+dx`, `-dx` and `+dx`, `dx = z / sqrt(2)`. The multiline paths
-follow the same lines. In the frame where one family is horizontal, the other two
-cross in rows `h` apart, alternating by half a period, at height
-`tau = -3 * dx (mod h)` above the horizontal line below them. The crossings split
-every band between horizontal lines into up-pointing triangles of height `tau`,
-down-pointing triangles of height `h - tau`, and hexagons. At `tau = 0` (and `h`)
-all three families meet at common points, as in Triangles. At `tau = h / 2` the
-triangles are equal, as in Tri-hexagon. The origin of that frame is always a
-3-fold center, whatever z is, so the per-layer rotation keeps the lines in place.
-
-Each band holds two paths that touch at its crossings: the upper one takes the
-V below the crossing and runs along the top horizontal line, and the lower one
-takes the inverted V above it and runs along the bottom line. Both are the same function
-of `tau`, the lower one mirrored with `h - tau`. `cubic_upper_level()` builds one
-period of the upper path as the lower envelope of five lines, clipped from below:
-
-- the two slanted lines through the crossings,
-- the horizontal line, lowered when the triangle above it is less than `1.5 * d1` high,
-- the two chamfers where the path turns onto and off the horizontal line, `d1 / 2`
-  from those crossings,
-- the flat cut into the V at the crossing.
-
-The cut height `clamp(tau - d1 / 2, 0, h - d1) + d1` is what makes the pattern
-continuous in z. While both triangles are at least `1.5 * d1` high, every
-crossing is a pair of bends `d1 / 2` from it, as in Tri-hexagon. When a triangle
-is thinner, its three paths stack like a triple crossing. The path through it
-flattens toward its base line and lies on it once the triangle is under `d1 / 2`
-high, and the paths beside it are pushed `d1` away. The layout thus reaches the
-Triangles one where the families meet. Adjacent paths stay at least `d1` apart
-at every `tau` and at every density up to 100%.
-
-## Adaptive Cubic
-
-Adaptive Cubic and Support Cubic take their lines from an octree of cubes
-standing on a corner. On each layer every cube cuts its three mid-planes into
-segments of the same three 60° families as Cubic, but the pattern is not
-periodic. Smaller cubes near the surface add finer lines, and a finer line ends
-where it meets the wall of its coarser cube, so the lines form crossings and
-T-junctions. `FillAdaptive::multiline_paths()` builds the paths from these
-segments directly, for each fill region and within `4 * d1` of it.
-
-At a crossing the two paths bounce as in Cubic. At a T-junction the through line
-runs straight on and the path of the ending line stops there. Every path still
-runs left to right in the frame where one family is horizontal, and that family
-rotates with the layer.
-
-Every line of every cube size lies on one fine lattice, so crossings closer than
-a few `d1` are the corners of one small triangle of that lattice, as in Cubic.
-The cuts follow the Cubic rules without a closed formula:
-
-- The two bends of a crossing are cut `d1` apart, `d1 / 2` each, perpendicular
-  to their bisector, so their walls touch. A cut goes no further than the path
-  end, and the other bend takes the rest of `d1`.
-- At the tip of a small triangle, between the two slanted families, a cut also
-  goes no further than the neighbouring bend turning the other way, and the
-  path beyond that bend is kept a wall away from it. The bends onto the
-  horizontal family are not limited this way: pushing their paths apart would
-  open gaps between walls that should touch.
-- A cut moves the path only where the cut line lies beyond it, near its bend.
-  The sharp bends between the two slanted families are cut after the bends onto
-  the horizontal family, so the tip of a small triangle wins, as in Cubic.
-- A path stopping at a T-junction is trimmed until it is `d1` less half a line
-  spacing from every other path, so that its end overlaps the wall it stops on
-  by half a line and bonds to it. The paths are trimmed one at a time against
-  the others as already trimmed, so two ends facing each other meet instead of
-  both backing off. A path stopping on the line of another is trimmed before
-  that one, so it gives way and the other still reaches the line it stops on. A
-  second round trims every path again from its full length, so an end grows
-  back where the ends it gave way to were trimmed later, and a last round only
-  shortens them, keeping them that far apart. Paths shorter than `d1` are left
-  out.
-- A line that ends on another less than `2 * d1` past a crossing stops at that
-  crossing instead, the shorter one where both do. The path along such a stub
-  would be trimmed away, leaving a hole between the walls that were cut to
-  touch it.
-
-Short paths enclosed by coarser lines still print as closed outlines, but most
-paths run on across several cells.

-# Precise Seam — High Level Design
-
-## Purpose and scope
-
-Precise Seam places the seam where a helper volume intersects the external
-wall. The user attaches a mesh to an object as a Precise Seam modifier, and on
-every layer the seam placer reads the modifier's slice to decide where the seam
-of each external perimeter may, must or must not go. The same mesh keeps
-working after the model changes, so the seam does not have to be repainted
-after every design revision, and a swept helper body can guide the seam along
-any path.
-
-The modifier is non-printing geometry. It does not take part in slicing, region
-assignment, filament selection or brim adhesion. It affects only seam
-placement, which runs during G-code export.
-
-## Volume types and priority
-
-Precise Seam adds six `ModelVolumeType` values after `SUPPORT_ENFORCER`. The
-strong types come first and the weak types follow. `is_precise_seam()`,
-`is_precise_seam_strong()` and `is_precise_seam_weak()` are range checks that
-depend on this order.
-
-| Type | Group | Effect on the perimeter |
-| --- | --- | --- |
-| `PRECISE_SEAM_CENTER` | strong | seam at the arc-length midpoint of the intersection |
-| `PRECISE_SEAM_LEFT` | strong | seam at the first point of the intersection |
-| `PRECISE_SEAM_RIGHT` | strong | seam at the last point of the intersection |
-| `PRECISE_SEAM_ENFORCED` | weak | intersection marked as enforced |
-| `PRECISE_SEAM_BLOCKED` | weak | intersection marked as blocked |
-| `PRECISE_SEAM_NEUTRAL` | weak | intersection reset to neutral |
-
-A strong modifier fixes one point. A weak modifier only changes the
-enforced/blocked type of seam candidates, and the configured seam position then
-chooses among them. First and last are taken along the perimeter made
-counter-clockwise seen from above. On an outer wall seen from outside, Left is
-the left end of the intersection. On the wall of a hole seen from inside the
-hole, the two ends are swapped.
-
-The order of volumes in the object is the priority order, highest first.
-`ModelObject::sort_volumes()` keeps every strong modifier before every weak one
-and preserves the user's order within each group. The object list lets the user
-drag a modifier only within its own group. A type change that crosses a group
-boundary moves the volume to the end of its new group, where it has the lowest
-priority. Strong modifiers are tried in this order, and the first one that
-yields a seam on a perimeter wins. Weak modifiers are applied from the lowest
-priority to the highest, so the highest one overwrites any overlapping zone.
-
-## Model storage and 3MF compatibility
-
-Projects must stay readable by earlier releases, and the modifier must not
-change a print there. Both 3MF writers therefore store a Precise Seam volume as
-an ordinary parameter modifier: `modifier_part` in the Bambu-format part
-subtype, and `ParameterModifier` together with the legacy `modifier` flag in
-the Prusa-format volume metadata. The seam mode is written separately under
-`precise_seam_type`, using the names from `ModelVolume::type_to_string()`
-(`precise_seam_center` and so on).
-
-On load, the mode applies after all other volume metadata, regardless of XML
-key order, and only when the base type is a modifier. Missing or unknown modes
-leave an ordinary modifier. Seam metadata on any other base type is ignored.
-Files that stored the seam mode directly as the volume type still load.
-
-A Precise Seam volume keeps any per-volume settings it had as a part or
-modifier, but they are inactive and the object list shows no settings item for
-it. The writers prefix these keys with `precise_seam_config:`, so an earlier
-reader drops them as unknown options. The volume therefore loads there as a
-modifier without settings and has no effect on the print. The current reader
-restores the keys only when the volume ends up as a Precise Seam type, so the
-settings return when the user changes the type back. Configuration values are
-XML-escaped in both writers, for every volume type.
-
-## Print invalidation
-
-`Print::apply()` compares the Precise Seam volumes of each object by type, ID
-and transformation. Adding, removing, moving, reordering or retyping one
-cancels background processing and invalidates only `psGCodeExport`; the sliced
-layers are kept. `model_volume_list_update_supports_and_seams()` then brings
-the support and Precise Seam volumes of the print's model copy in line with the
-new model in one pass. A volume may switch between the two families, since
-neither affects slicing. A conversion to or from a part or ordinary modifier
-changes the solid and modifier volume lists and reslices as before.
-
-## Modifier slices
-
-`SeamPlacer::init()` collects the Precise Seam volumes of each object once:
-strong ones in priority order and weak ones reversed. It slices each volume
-separately with `PrintObject::slice_single_volume()`, which shares
-`slice_modifier_volumes()` with support blockers and enforcers but does not
-merge volumes, so each keeps its own priority. The result is cached per volume
-and indexed by object layer; `Layer::id()` includes raft layers, which are
-subtracted. Seam candidates are then gathered in parallel over the layers and
-read the cache without locking.
-
-Objects without Precise Seam volumes follow the unchanged seam placement path.
-For objects that have them, perimeter extraction also removes consecutive
-duplicate points and the repeated closing point of each extrusion loop.
-Zero-length edges at path junctions would otherwise prevent point insertion
-there. Distinct visits to one point of a self-touching contour are kept.
-
-## Finding the wall segment
-
-The seam placer works on the external perimeter loops of each layer, both
-outer contours and holes, each made counter-clockwise. For every modifier
-polygon on the layer that overlaps the perimeter's bounding box, the region
-enclosed by the perimeter is clipped against the modifier polygon. The boundary
-of each intersection polygon alternates between runs that follow the perimeter
-and runs that follow the modifier outline. The wall segment is the longest
-continuous run of intersection vertices that lie on the perimeter, measured in
-vertices.
-
-The fast path first finds an intersection vertex that exactly matches a
-perimeter vertex. It then walks forward and backward, expecting the adjacent
-perimeter vertex and falling back to projection when Clipper has merged or
-split collinear edges. A vertex counts as on the perimeter when its projection
-is within about 1.6 nm, which covers Clipper's rounding. If no vertex matches
-exactly, or every vertex lies on the perimeter, the general path projects all
-vertices. When every vertex is on the perimeter, the edge midpoints are checked
-instead: a modifier chord can join two perimeter vertices directly, and the
-chords split the vertex ring into runs. If no edge leaves the perimeter, the
-perimeter lies entirely inside the modifier.
-
-`Polygon::point_projection()` optionally reports the edge that holds the
-projection, and every point of the segment keeps the index of its perimeter
-edge. New points are inserted on that edge. A point within 1 µm of an existing
-vertex snaps to that vertex instead.
-
-## Strong modifiers
-
-For a strong modifier, the target is the first point, the last point or the
-arc-length midpoint of the segment. The midpoint is projected back onto the
-original perimeter, because Clipper may have merged several perimeter edges
-into one segment edge. The target is inserted into the perimeter, and a helper
-point is inserted 1 µm before and after it. Strong modifiers are tried in
-priority order, the first valid intersection decides the seam, and weak
-modifiers are not processed for that perimeter.
-
-When candidates are built, the inserted point is the only enforced candidate
-and becomes the central enforcer; every other candidate is blocked. The seam
-position modes then pick that point: Aligned and Aligned Back prefer the central
-enforcer, while Back, Random and Nearest rank enforced candidates above blocked
-ones. Alignment and random placement can still move the final position along an
-edge. After alignment, `restore_precise_seam_positions()` writes the exact point
-and its index back into every perimeter that has a strong seam. Inner walls take
-their seam from the external seam as usual, including staggering.
-
-## Weak modifiers
-
-Weak modifiers produce one segment per intersection polygon, so one modifier can
-mark several zones on one perimeter. All segment boundaries are inserted into
-the perimeter in order of decreasing arc length. Each insertion then leaves the
-indices of the pending, shorter ones unchanged; a point on the closing edge is
-appended rather than inserted at index zero. A helper point is added 1 µm
-outside each boundary. Random placement picks a position along the edge that
-follows a candidate. These helpers keep that edge 1 µm long at each boundary, so
-a zone cannot extend or intrude further than that. Boundaries that coincide
-share their helper points.
-
-The zone types are then resolved in priority order, and the edges of enforced
-zones are subdivided into steps of at most
-`SeamPlacer::enforcer_oversampling_distance` (0.2 mm). The middle candidate of
-the longest enforced patch is therefore close to the geometric middle of the
-zone. That patch is measured in candidates, across the closing edge, regardless
-of where the contour starts; the same rule applies to painted seams.
-
-Candidates first receive their type from seam painting. The weak zones then
-overwrite it, lowest priority first. Blocked and Enforced zones therefore take
-precedence over painting, and Neutral clears painting inside its zone.
-
-## Unsupported geometry and warnings
-
-Some modifier shapes cannot be resolved to one seam or one zone per crossing.
-They are detected cheaply and reported rather than guessed:
-
-- A strong modifier that crosses a perimeter in more than one place uses only
-  its first valid segment. The other crossings are ignored.
-- A modifier that crosses the whole region enclosed by the perimeter is
-  detected when the modifier outline minus that region leaves more than one
-  piece, none of them a hole. Its intersection holds two wall runs, and only
-  one of them is used.
-- A modifier whose slice has a hole on a layer, found as a clockwise polygon in
-  the flattened slice, is skipped on that layer. The flattened slice no longer
-  records which hole belongs to which contour.
-- A perimeter that lies entirely inside a modifier is ignored by that modifier.
-
-The conditions are atomic flags shared by all layers and objects. After all
-objects are processed, `SeamPlacer::init()` issues at most one non-critical
-warning with the ID `SlicingPreciseSeamWarning`. The warning is a single line
-that lists every cause found, because the export warnings dialog shows only the
-first line of each warning. Repeated warning events replace this notification
-instead of appending text to it.
-
-## User interface
-
-- *Add Precise Seam* in the object menu creates a Center modifier from a
-  primitive or a loaded mesh. Text and SVG volumes cannot become Precise Seam
-  modifiers: the menu does not offer them, and `ObjectList::set_volume_type()`
-  refuses the change.
-- *Change Type* has a single *Precise Seam* entry. It converts other volumes to
-  Center and keeps the mode of volumes that are already Precise Seam. The
-  *Precise Seam Type* submenu appears only when every selected item is a
-  Precise Seam volume, including settings rows that resolve to one. It sets the
-  chosen mode on all selected volumes.
-- Each mode has its own icon in the object list and its own color in the 3D
-  view, at 60% opacity: warm oranges for the strong modes, and green, red and
-  gray for Enforced, Blocked and Neutral.
-- Object list drops map visible rows to volume indices while skipping hidden
-  cut connectors, and they refresh the row-to-volume map of the object.
-- Precise Seam volumes have no filament, block pasting into SLA, and are exposed
-  to Python plugins as `ModelVolumeType` values plus the `is_precise_seam*()`
-  methods.

-# Prime tower sparse layers — High Level Design
-
-## Purpose and scope
-
-A prime tower exists to absorb filament changes, but it is planned on every
-object layer below the topmost change, not only on the layers that purge. The
-layers in between carry no filament change and print nothing but a block of the
-tower's own footprint to keep its top level. They are called sparse layers, and
-on a print with few changes they are most of the tower: they cost time, filament
-and a travel to the tower on every layer.
-
-Two settings trade that cost against something else. `wipe_tower_no_sparse_layers`
-drops them, which sinks the tower below the model. `wipe_tower_sparse_layers_combination`
-merges runs of them into fewer, thicker layers, which keeps the tower level with
-the model. Both are off by default, and with both off the tower prints one layer
-per object layer as it always has.
-
-The decisions belong to tower planning and G-code emission. They do not change
-sliced object geometry, but they do change the emitted G-code, the filament and
-time estimates, and — for the compacted case — whether a plate is printable at
-all. Changing either setting invalidates the tower step.
-
-## What a sparse layer is
-
-`ToolOrdering::fill_wipe_tower_partitions` counts the filament changes per layer
-and propagates that count downwards, so every layer below the topmost change is
-marked as carrying a tower. It then fills any gap between two tower layers, so
-the tower is continuous from the bed to its last purge. `wipe_tower_layer_height`
-is the distance from the previous tower layer, which is the object's layer height
-whenever the tower prints on every layer.
-
-`Print::_make_wipe_tower` plans one tower layer per such object layer. A layer
-whose only call keeps the current filament leaves no toolchange in the plan, and
-the layer it generates is a single result whose initial and new tool are equal.
-That is what `wipe_tower_layer_is_sparse` recognises, and it is the unit both
-settings work on.
-
-The plan stays one entry per tower layer in every case. The G-code emitter walks
-`WipeTowerData::tool_changes` by layer index, advancing once per object layer
-that carries a tower, so a planner that removed entries would silently shift
-every later layer onto the wrong tower geometry. Layers that print nothing are
-therefore still planned and still generated; they are marked, and the emitter
-drops them.
-
-## Shared rules
-
-Tower planning, G-code emission and the plate validation all have to agree about
-which layers print and where. They ask one set of free functions, declared beside
-the tower classes, rather than each re-deriving the answer from the raw options:
-
-- `wipe_tower_sparse_layers_skipped` — whether sparse layers are really dropped.
-  Smooth timelapse and clumping detection park the nozzle on the tower every
-  layer, so with either of them on no layer is ever dropped and the option reads
-  as off everywhere.
-- `wipe_tower_sparse_layers_combined` — whether runs are really merged. The same
-  two rule it out, and so does `wipe_tower_no_sparse_layers`: dropping the layers
-  outright is the stronger answer to the same problem, so the two settings are
-  exclusive and the GUI greys out the second while the first is on.
-- `wipe_tower_layer_is_sparse`, `wipe_tower_layer_is_combined_away` — per-layer
-  questions the emitter asks about generated results.
-- `compute_compacted_wipe_tower_z` — the tower's print z per planned layer when
-  it is compacted.
-- `combine_sparse_wipe_tower_layers` and its `combine_sparse_wipe_tower_plan`
-  wrapper — the merge rule, applied to either generator's plan.
-
-Both tower generators are driven through these. `WipeTower` (Type 1, the block
-tower) and `WipeTower2` (Type 2, the default) keep separate plans with the same
-per-layer shape — print z, layer height, toolchanges, and a `combined_away` flag
-— so one template covers both.
-
-## Dropping sparse layers
-
-With `wipe_tower_no_sparse_layers`, the tower only grows on layers that carry a
-real change. It therefore falls one layer height behind the object for every
-sparse layer, and by the top of a tall print it can sit far below the model. The
-nozzle has to reach down to it at each purge.
-
-`compute_compacted_wipe_tower_z` derives that z once, from the generated results,
-so the emitter and the validator cannot disagree. Emission descends to it, but
-only once the nozzle is parked over the tower: descending while still over the
-model would drive the nozzle into the print, so a descent that would do that is
-deferred until after the travel to the tower. Extrusions emitted without an
-explicit z — the nozzle-change wipe in particular — are pulled down to the
-compacted z for the same reason.
-
-Reaching down is only safe if nothing tall stands near the tower. `Print.hpp`
-carries the clearance rule: a keep-out zone grown from the tower's footprint by
-the spiral z-hop envelope, and a per-object limit on how high an object may rise
-near it, tiered by the nozzle cone, the head body, the rod and the lid. The same
-rule serves the precise check on real extrusions, the pre-slice estimate that
-feeds the plater, and the outlines the plater draws while an object is dragged,
-so that the ring the user sees touches the object's outline exactly when the
-check trips.
-
-## Merging sparse layers
-
-With `wipe_tower_sparse_layers_combination`, no layer is dropped and nothing is
-compacted: the tower keeps following the object, and the nozzle never descends.
-Instead a run of consecutive sparse layers prints once, on the run's last layer,
-at the accumulated height of everything it covers — the same way infill
-combination merges sparse infill. The layers below it in the run print nothing.
-
-`combine_sparse_wipe_tower_plan` runs before the tower's depths are planned,
-because the heights it rewrites feed the extrusion flow of every later pass. It
-raises `height` in place on the layer that prints a run and sets `combined_away`
-on the rest; generation then proceeds unchanged, and the flag is copied onto the
-results so the emitter can drop them.
-
-Four constraints shape the rule:
-
-- **Whole layers only.** A tower layer is entered at the object's z, so a merged
-  layer has to end on an object layer boundary. The merged height is therefore a
-  sum of whole layer heights, never a clamped value.
-- **The nozzle's maximum layer height.** A run stops growing as soon as one more
-  layer would pass `max_layer_height` for the nozzle printing it — three quarters
-  of the nozzle diameter when that is left at 0, as elsewhere in slicing. The cap
-  is read through the filament-to-nozzle map, since `max_layer_height` is per
-  nozzle while the tower indexes filaments. This is what makes the setting inert
-  at common layer heights: two 0.2 mm layers are 0.4 mm and do not fit under a
-  0.3 mm maximum, so nothing merges until the layer height is 0.15 mm or below,
-  or the maximum is raised.
-- **A filament change purges at its own z.** A layer with a real change can
-  neither be merged away nor absorb the run below it, so a run always ends on its
-  own last sparse layer and the change above it is untouched.
-- **The first layer stays on the bed.** It carries the brim and is never merged.
-
-A run holds one filament throughout — that is what makes it sparse — so the cap
-is uniform across it, and the tower reserves depth only for the purges above a
-layer, so a run has one footprint and the merged layer covers exactly the area
-the layers it replaces would have.
-
-## Emission and accounting
-
-`WipeTowerIntegration` drops a layer whose results are marked, for both settings,
-through the same `ignore_sparse` path in `tool_change` and
-`is_empty_wipe_tower_gcode`. A dropped layer emits no travel to the tower and no
-extrusion.
-
-Filament used is accumulated by the generators while they write, so a layer that
-will be dropped must not be charged. Type 1 asks `layer_is_printed` at each of
-its accumulation points; Type 2 guards the equivalent block in `finish_layer`,
-which also stops a merged-away layer from adding height of its own — the layer
-that prints the run carries all of it.
-
-A merged layer is the only case where the tower's layer height differs from the
-object layer it sits on, and therefore the only case where the height the
-exporter already emitted for that layer is wrong for the tower. Both generators
-do declare a height, but each hardcodes a tag dialect — the block tower forces
-the BBL tag, the other writes the compatible one — while the G-code processor
-reads only the tag its printer uses. On a non-BBL printer with a Type 1 tower the
-declaration is dropped, and the merged layer is drawn and costed as a thin one.
-`WipeTowerIntegration::tower_height_tag` therefore declares it at export time,
-where the printer is known, and only when the tower's own G-code does not already
-carry the tag that will be read. The object's height returns on the next object
-path, because emission forces the processor role to the tower on any layer that
-carries one.
-
-## Constraints
-
-A layer that prints nothing prints nothing at all, including any interface work
-the tower planner scheduled there. The Type 1 block planner marks a layer as a
-contact layer when a filament category stops or starts being used relative to the
-layer below, and a sparse layer immediately above a change qualifies. Merging a
-run, like dropping its layers, replaces that interface with the run's single
-layer. Both settings are off by default for this among other reasons.
-
-Neither setting changes what the tower is for. A plate that needs a tower on
-every layer — smooth timelapse, clumping detection — gets one, and the settings
-read as off rather than compacting or merging in one place and not another.

-# Printer agents
-
-Printer agents isolate printer-specific communication from the rest of OrcaSlicer. The GUI and
-`DeviceManager` operate on a shared set of printer operations and device state; a selected printer
-agent implements those operations for a particular printer ecosystem. The agent boundary allows
-Bambu, Moonraker-based printers, built-in integrations, and Python-provided integrations to use the
-same application workflow without making the GUI understand every printer protocol.
-
-The current boundary is an adapter boundary around the existing application contract. In particular,
-some request fields and message payloads still use the Bambu-shaped representation that existing
-`MachineObject` and `DeviceManager` code consumes. The printer agent is responsible for translating
-that representation into the protocol spoken by its printer. This is an intentional compatibility
-constraint of the current design; the interface is not yet a neutral printer protocol.
-
-The v1 dialect migration path is deliberately narrow. `DeviceManager` currently speaks the Bambu JSON
-dialect because that is the payload shape already used throughout the command and state workflow. The
-v1 `OrcaPrinterAgent` also accepts that Bambu dialect. Its transport path places the small translation
-needed for the target printer at `deliver_to_sink`, keeping the compatibility code at the edge rather
-than spreading it through `DeviceManager` or the agent interface.
-
-The eventual direction is for `DeviceManager` to produce an Orca JSON dialect. The Bambu agent will then
-own the translation from Orca JSON to Bambu's protocol, while `OrcaPrinterAgent` can forward the Orca
-payload directly to its sink. The v1 translation at `deliver_to_sink` can then be removed without
-changing `DeviceManager`, the command callers, or the rest of the agent workflow.
-
-## Components
-
-The system has four relevant layers:
-
-```text
-GUI / DeviceManager / MachineObject
-              |
-        NetworkAgent
-          /       \
- IPrinterAgent   ICloudServiceAgent
-      |                 |
- printer protocol   authentication and cloud services
-```
-
-### `DeviceManager` and `MachineObject`
-
-`DeviceManager` owns the application-facing printer workflow. It maintains `MachineObject` instances,
-updates their state, filters devices for the active printer agent, and initiates operations such as
-homing, temperature changes, printing, subscriptions, and camera playback.
-
-`MachineObject` remains the shared state model used by the GUI. It does not contain the implementation
-of a printer protocol. When a device is discovered or returned by a cloud query, the device is tagged
-with the active `printer_agent_id`. Device lists and selected-machine operations use that tag to avoid
-sending an operation through an agent that does not own the device.
-
-### `NetworkAgent`
-
-`NetworkAgent` is the façade used by the GUI and `DeviceManager`. It owns:
-
-- the currently selected `IPrinterAgent`;
-- the registered cloud-service instances, indexed by provider;
-- callbacks shared by the active printer agent and the application;
-- the forwarding methods for printer commands and cloud operations.
-
-There is one active printer agent for the currently selected printer preset. Switching the preset
-increments the machine-list generation, disconnects the old printer agent, removes its callbacks, and
-installs the newly selected agent. The façade then forwards printer operations to that agent.
-
-Cloud operations are selected separately using a provider key. `NetworkAgent` forwards a cloud request
-to the matching `ICloudServiceAgent`, and forwards cloud camera operations with a device ID. The
-printer agent receives a cloud-agent pointer through `set_cloud_agent()` when it is created, allowing
-printer communication to obtain cloud tokens without depending on a concrete cloud implementation.
-
-### `IPrinterAgent`
-
-`IPrinterAgent` is the printer-facing contract. It covers:
-
-- cloud-relay and direct-LAN message delivery;
-- LAN connection, discovery, binding, and certificates;
-- printer subscriptions and callbacks;
-- print operations;
-- filament synchronization;
-- camera capability and local camera URL reporting;
-- printer command methods.
-
-Concrete built-in implementations include the Bambu wrapper, the native Orca/Moonraker path, and
-other printer-agent implementations registered by the application. A printer agent may use either
-the cloud agent, a direct LAN connection, or both.
-
-### `ICloudServiceAgent`
-
-`ICloudServiceAgent` owns authentication and services provided by a cloud backend. It covers login
-state, tokens, user and printer lists, settings synchronization, model services, cloud messages, and
-cloud camera operations.
-
-Cloud camera operations are device-scoped:
-
-- `get_camera_url(dev_id, callback)` obtains a stream URL for one device;
-- `create_camera_signaling_channel(dev_id)` creates signaling for one device where the provider
-  supports it.
-
-This is separate from the local camera URL exposed by `IPrinterAgent`, which is currently scoped to
-the active printer agent because a normal LAN agent represents one physical printer connection.
-
-## Agent registration and selection
-
-`NetworkAgentFactory` maintains the printer-agent registry. Each registry entry contains an agent ID,
-a display name, and a factory function. Built-in agents register during application initialization.
-Python printer-agent capabilities register dynamically and contribute an agent ID and factory entry.
-
-The selected printer preset contains the printer-agent choice. If no explicit choice is stored, the
-application preserves the existing default behavior: Bambu presets select the Bambu agent and other
-presets select the native Orca agent. When a preset is changed, `GUI_App` resolves the effective agent
-ID, obtains the corresponding cloud agent, creates the printer agent through the registry, and installs
-it in `NetworkAgent`.
-
-The registry rejects conflicting agent IDs. This matters for Python plugins because an agent ID is the
-stable identity used by presets and device ownership; two enabled plugin capabilities must not claim
-the same ID.
-
-## Message and command flow
-
-There are two low-level message paths:
-
-- `send_message()` publishes a command through the printer's cloud relay;
-- `send_message_to_printer()` sends a command directly to the printer over the LAN path.
-
-Both paths accept a JSON string, quality-of-service and flag values, and return the existing network
-status code domain. The agent owns the conversion from that JSON contract to its native transport.
-
-The typed `command_*` methods are the application-facing convenience layer. The five generic defaults
-currently implemented by `IPrinterAgent` construct the existing JSON dialect and route through the
-same message path:
-
-| Method | Default operation |
-| --- | --- |
-| `command_xyz_abs()` | Send `G90` for absolute positioning |
-| `command_auto_leveling()` | Send `G29` for bed leveling |
-| `command_go_home()` | Use the supported homing operation or send `G28` |
-| `command_set_bed()` | Use the supported bed control or send `M140` |
-| `command_set_nozzle()` | Send `M104` for nozzle temperature |
-
-These are compatibility defaults for common printer workflows, not a guarantee that every firmware
-implements every command identically. An agent can override a method when its protocol needs another
-operation. For example, a Klipper configuration may use `BED_MESH_CALIBRATE` instead of `G29`.
-
-The remaining common command methods default to `ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED` because their
-existing behavior is vendor-specific or has no portable implementation:
-
-- AMS RFID refresh;
-- AMS calibration;
-- AMS tray selection;
-- camera start;
-- axis control.
-
-The methods remain on the common interface so an agent that supports them can override them explicitly.
-`sequence_id` remains part of the command contract because `DeviceManager` creates and tracks it as
-the command ID.
-
-## Device ownership and stale responses
-
-Printer-agent ownership is represented by `printer_agent_id` on device records and `MachineObject`
-instances. The active agent ID is attached when a device is discovered, returned by a cloud list, or
-reused after a preset switch. Local-machine configuration also persists the agent ID so a saved LAN
-device is not silently reused by an unrelated agent.
-
-Cloud printer-list responses carry three pieces of request context added by `NetworkAgent`:
-
-```text
-provider   cloud provider used for the request
-agent_id   active printer agent when the request was made
-generation machine-list generation when the request was made
-```
-
-`DeviceManager` accepts the response only when those values still match the current provider, active
-agent, and generation. This prevents a slow response from the previous preset or provider from
-repopulating the current device list.
-
-The provider mapping is currently selected by `GUI_App`: the Bambu agent maps to the Bambu cloud
-provider and other agents map to the Orca cloud provider. The generation check protects that existing
-selection from races; it does not make cloud-provider ownership intrinsic to an agent. Cloud-printer
-ownership and the broader Orca cloud services are therefore still separate architectural concerns.
-
-## Python printer agents
-
-`PrinterAgentPluginCapability` implements `IPrinterAgent` directly. The live capability object is
-registered with `NetworkAgentFactory` and handed out as the printer agent when its agent ID is selected.
-The plugin receives the selected `ICloudServiceAgent` through `set_cloud_agent()` just like a built-in
-printer agent.
-
-Python plugins must implement the core communication and lifecycle methods required by the interface,
-including agent metadata, printer connection, discovery callbacks, and the two message-send methods.
-Methods that are meaningful only to a particular printer are optional overrides where the C++ base
-class provides a default.
-
-All ten `command_*` methods are available in the Python binding and in the trampoline. Their override
-status is intentionally optional:
-
-- the five generic commands use the C++ default when Python does not override them;
-- the five vendor-specific commands return `NOT_SUPPORTED` unless Python supplies an implementation;
-- a Python implementation can replace either behavior for its own protocol.
-
-The Python camera binding exposes HTTP, HTTPS, RTSP, and HTTP-snapshot modes. WebRTC remains a
-built-in C++ camera mode, but is not exposed as a Python mode because the current Python capability
-does not provide the corresponding cloud signaling-channel contract.
-
-## Camera playback boundary
-
-The camera stream mode describes how a stream is obtained; it does not by itself define ownership of
-the wxWidgets view that renders it. `MediaPlayCtrl` selects and tears down the active backend, while
-the wx parent owns the child window or renderer. This is important because a web view, native media
-control, and frame-based/WebRTC renderer have different wx window-lifetime requirements.
-
-Cloud URL and signaling requests are routed through `NetworkAgent` to the cloud provider selected for
-the device. Local URL requests are routed to the active printer agent. The distinction keeps cloud
-account services device-scoped while preserving the current one-LAN-agent/one-printer model.
-
-## Compatibility constraints
-
-The printer-agent boundary intentionally preserves several existing application contracts:
-
-- Bambu-shaped JSON is still the shared command representation;
-- existing network status codes are reused, with Orca-specific unsupported/capability errors added
-  in the Orca-reserved range;
-- `MachineObject` remains the shared device-state model;
-- preset and local-machine data retain compatibility with the existing agent-selection behavior;
-- Python plugins use the existing capability and pybind11 registration system.
-
-The agent abstraction is therefore responsible for containing vendor differences, not for pretending
-that all vendor protocols are identical. The planned Orca JSON dialect is the protocol-neutral command
-model for the `DeviceManager`/agent boundary. Once it is introduced, Bambu-specific translation remains
-inside the Bambu agent and the Orca agent's v1 sink adapter can be removed as a self-contained cleanup.

-# Wipe inward — High Level Design
-
-## Purpose and scope
-
-Wipe inward reduces reheating of fresh plastic and visible seam artifacts by
-moving the hot nozzle toward adjacent printed material during the external-wall
-wipe. Wipe marks are especially visible at layer heights below 0.1 mm.
-The option applies only to wipes after external walls, including walls around
-holes. It does not offset wipes after inner walls, infill or supports. For an
-outer contour the move is inward; for a hole it is away from the hole, toward
-the surrounding material. The path must remain supported by material that is
-already present when the wipe executes.
-
-The operation belongs to G-code generation. It uses extrusion paths, their actual
-widths and their print order. Changing its settings invalidates G-code export
-while preserving the sliced geometry.
-
-## Settings and eligibility
-
-`wipe_inward` defaults to disabled and requires Wipe while retracting to be
-enabled for the active filament. `wipe_inward_distance` defaults to 50% of the
-actual external-wall extrusion width; it also accepts an absolute distance in
-millimeters. Using the path width makes Auto width and Arachne's variable widths
-meaningful. The effective offset is limited by that width and the spacing to the
-adjacent wall. A zero distance disables the offset.
-
-Only external perimeters with a suitable, previously printed inner perimeter
-are eligible. A configured wall count alone cannot establish eligibility:
-the local geometry may contain fewer walls, and walls scheduled later do not
-provide support. Outer/Inner wall order therefore normally retains the regular
-wipe path.
-
-Retraction and pressure advance calibrations disable inward wiping so it cannot
-mask the behavior being measured. The calibration settings turn it off, and
-G-code generation enforces this even if a profile or object override enables it.
-
-## Path selection and support
-
-The planner identifies an adjacent inner perimeter on the material side of the
-outgoing wall. Contour winding and the distinction between outer contours and
-holes establish a preferred direction; local printed geometry resolves ambiguous
-or self-touching contours.
-
-Candidate paths offset or translate the portion needed for the configured wipe
-distance. A wide seam gap can prevent a supported forward path; following the
-incoming printed wall backwards is also a candidate. If translating that wall
-cannot provide a complete wipe around a curve, the planner tries an offset of
-the reversed wall. Direction checks allow coordinate-rounding error at a
-perpendicular entry, while rejecting actual backtracking. The planner checks the
-complete executable path, including its connector from the nozzle position,
-against the current and earlier printed perimeters. Nearby endpoints alone do
-not establish support across a gap.
-
-Each region accumulates its printed perimeter prefix once, in extrusion order.
-Every entity contributes its geometry only after it is printed, and the prefix
-is discarded when the region ends. This collection is skipped when inward wiping
-is disabled or its configured distance is zero. A mixed inner-wall loop remains
-an eligible target even when its first path is an overhang: ordinary inner-wall
-paths elsewhere in the loop identify it. Likewise, an external loop with an
-overhanging start remains eligible when other segments identify the external
-wall. It is available for support checks but is not an inner-wall target.
-Candidate-specific support filtering and AABB trees are built only for eligible
-external loops, then reused across their candidate paths.
-
-Material-side validation applies with or without a seam gap. Along each
-candidate, local wall normals point toward the adjacent printed inner wall;
-samples on the opposite side are rejected even when they remain close enough
-to the external wall to pass the support check. This uses the open wall geometry
-without treating it as a closed polygon. Full paths at a zero-gap seam also
-retain clearance from the external wall after their initial connector. At a
-clipped corner, another branch can be closer than the requested offset, so
-material-side and support checks apply without that additional clearance rule.
-
-An accepted candidate replaces the stored wipe path as a whole. A short direct
-inward move is also eligible when longer candidates fail validation. It may
-waive full wall clearance, but must pass the material-side check. Its initial
-direction is checked from the actual nozzle position after any loop pre-move;
-the original wall endpoint is retained separately for intersection checks. It takes
-priority over the alternate offset when the preferred and translated paths
-are unusable. A longer reversed path may replace the selected candidate only
-when its distance to the target inner wall is no worse within tolerance.
-
-## Fallback to the regular wipe
-
-The original wipe path is retained when:
-
-- No suitable adjacent inner wall has already been printed near the seam. This
-  includes single-wall areas, locally missing inner walls and normally Outer/Inner
-  wall order. A distant wall or a wall on the air side does not qualify.
-- The requested or available offset, or the configured wipe distance, is zero
-  or too small at the geometry's coordinate precision.
-- Degenerate geometry prevents construction of a usable candidate, or all
-  candidates fail the checks for printed support, direction, wall clearance or
-  the connector from the actual nozzle position. This can occur at tight corners,
-  narrow features or seam gaps.
-
-Corners and seam gaps do not automatically trigger fallback: an offset,
-translated, reversed or short direct inward path may still be valid. The regular
-wipe is retained only when no candidate is accepted.
-
-Fallback uses the path and retraction rules for `wipe_inward` disabled.
-Wipe while retracting must still be enabled for a wipe to occur; `wipe_on_loops`
-remains controlled by its own setting.
-
-## Interaction with Wipe on loop
-
-`wipe_on_loops` is an independent option that makes a short move before leaving
-an external loop. It can operate with `wipe_inward` disabled. When both options
-are enabled, its destination is the starting position for the inward wipe.
-
-The loop move samples the outgoing and incoming paths by distance across path
-boundaries. The sampling distance is bounded by the nozzle diameter and one
-quarter of the total path length. It samples the outgoing path at up to 20% of
-the nozzle diameter and rotates that point around the seam through one third
-of the material-side corner angle. For a closed square outer contour, this
-produces a move of 20% of the nozzle diameter at 30 degrees into the corner.
-Coincident samples or degenerate angles suppress the move.
-
-The nozzle position stored by G-code generation must match the emitted loop
-move. Both travel planning and wipe execution depend on this position, including
-when Wipe inward is disabled.
-
-With a seam gap, a loop move may advance past the inward offset's original entry.
-If that alone makes the connector backtrack, the entry advances to the nozzle's
-projection on the offset. The planner extends the source as needed to preserve
-the configured wipe length and validates the new connector and complete path.
-Joins that already backtrack across the seam gap are not adjusted this way.
-
-## Execution and retraction
-
-The stored wipe path uses a sentinel first point. Execution starts from the
-actual nozzle position and proceeds to the second stored point. Path selection,
-support validation and wipe-length calculation must all use this same executable
-geometry, especially after a Wipe on loop move.
-
-An accepted inward path executes at the end of the external loop, after any
-Wipe on loop move, without retracting filament. It consumes the stored path and
-updates the nozzle position before travel planning. A short travel to the next
-wall cannot discard this wipe or force a retraction or Z-hop. Subsequent travel
-uses the normal minimum-travel threshold and retraction/lift settings from the
-new position. The regular wipe, including fallback, remains deferred until a
-normal retraction uses it.
-
-Retraction is divided into portions before, during and after wiping. The amount
-that can be retracted during the wipe depends on its executable length, wipe
-speed and the active filament's retraction speed. Fractional retraction speeds
-are retained in this calculation. For a 2 mm wipe at 100 mm/s and a retraction
-speed of 25.5 mm/s, the wipe can retract 0.51 mm. With a total retraction of 0.8 mm
-and both before/after percentages set to zero, the remaining 0.29 mm is retracted
-before wiping. This split applies to regular deferred wipes, including fallback;
-an accepted inward wipe executes separately without retraction.
-
-## Implementation and verification
-
-- [GCode.cpp](../../src/libslic3r/GCode.cpp) integrates path selection, nozzle
-  position and retraction; [Print.cpp](../../src/libslic3r/Print.cpp) controls
-  invalidation, and [PrintConfig.cpp](../../src/libslic3r/PrintConfig.cpp) defines
-  the settings.
-- [WipePathHelpers](../../src/libslic3r/GCode/WipePathHelpers.hpp) implements path
-  sampling, offset selection and support checks.
-- [Geometry tests](../../tests/libslic3r/test_wipe_path.cpp) cover support,
-  degenerate paths, contour and hole orientations, and exact loop-move geometry
-  across path subdivisions.
-- [FFF tests](../../tests/fff_print/test_wipe.cpp) cover emitted trajectories,
-  fallback, minimum-travel retraction and Z-hop rules, and export invalidation.
-  With Wipe inward disabled, they check the loop move's direction and magnitude
-  for Classic and Arachne, the subsequent wipe's start and length, and fractional
-  retraction splitting in absolute and relative E modes.
-  Loop-move checks use reserved role/wipe markers and extrusion state, and run
-  with human-readable G-code comments both enabled and disabled.
