HanifKoh 00429da739 Apply the GUI's Mixed Filament Rules on the CLI (#15636)
A valid mixed filament already slices the same on the CLI as in the GUI;
these are the places where the CLI still skipped a rule the GUI applies.

- Keep the prime tower when a mixed filament is used, even if every
  --load-filaments preset is the same. A mixed filament swaps between its
  components every layer, so turning the tower off left the swaps with
  nothing to purge on.
- Leave a mixed slot's row and column of the flush matrix at zero when
  --filament-colour triggers a recompute, as the GUI does; a mixed slot
  never reaches a nozzle.
- Refuse a mixed slot that has no filament of its own. Feature filament
  ids aimed at it were past the filament count, got reset to filament 1
  and the model silently printed in one colour.
- Refuse a plate that uses a mixed filament whose components are
  different filament types, the type half of the GUI's
  Sidebar::has_broken_mixed_filament. Missing or out-of-range components
  are already rejected for the whole project by validate().
  get_extruders_under_cli gains an expand_mixed_slots flag so the gate
  can see mixed slots rather than their components; existing callers
  keep the expanded list.

Both refusals exit with the new CLI_MIXED_FILAMENT_INVALID (-69).

HanifKoh 31f6eb2718 Keep the First Value When a Per-Filament Variant Option Is Too Short (#15639)
update_values_to_printer_extruders_for_multiple_filaments picks each
filament's value from the flattened (filament x variant) columns of every
per-filament variant option. When a column index fell past the end of the
option's values, it skipped that filament and left the zero the output
vector was created with.

The GUI always hands this function full columns, but the CLI does not:

- a CLI override of a single value, such as --nozzle-temperature=211 on a
  four-filament project, came out as 211,0,0,0, so three filaments would
  print at 0 C;
- loading fewer filament presets than the project has filaments left the
  remaining filaments' columns missing, so filament_cooling_before_tower
  came out as 10,10,0,0 and filament_ramming_volumetric_speed as -1,-1,0,0.

An out-of-range column now keeps the option's first value, the fallback
get_at() and the sibling gather step already use. The seven per-type copies
of the loop are replaced by that same gather_option_values helper, moved
above the function; it now takes its caller's name for its log lines. An
empty option, which has no first value, is given one registered default per
filament first; it used to be replaced with zeros.

On a partial load a filament whose preset was not loaded takes the first
filament's value rather than its own preset's, which the CLI does not load;
for the options seen in practice those agree.

HanifKoh f21f062ded Cache compiled objects between CI runs (#15611)

Every CI build leg compiles the whole tree from scratch: 42 to 57
minutes of each build job, on every push and every pull request, roughly
200 runs a week. This PR caches the compiled objects with ccache so that
a run only compiles what changed since the last push to main. With a
warm cache the compile steps take 1 to 4 minutes on all six legs and a
pull-request run finishes in about 30 minutes instead of 75.

Three prerequisites landed last week and made this measurable: #15537
took `GIT_COMMIT_HASH` off the compile line, #15552 made a build without
the precompiled header work on Windows, and #15501 stopped the Flatpak
job from rebuilding its dependencies.

## Changes

### Compiler cache in `build_orca.yml`

Each build leg (Linux x86_64/aarch64, Windows x64/arm64, macOS
arm64/x86_64) restores a cache entry keyed by that leg, compiles through
`ccache` via `CMAKE_<LANG>_COMPILER_LAUNCHER`, and prints its hit
statistics at the end of the job. The macOS universal combine does not
compile and is left out.

Who writes the cache is the important part. Cache entries are immutable
and a restore always takes the newest matching one, so every save is a
new entry that is never read again once a newer one exists. Therefore:

- **Pushes save.** After a successful save, the older entries for the
same leg on the same ref are deleted, so a branch holds exactly one
entry per leg. The save comes first, so a failed save leaves the
previous entry in place.
- **Pull requests restore only.** They read main's entries (GitHub lets
a PR read the base branch's caches) and keep nothing. Saving from PRs
would add about 6 GB per run that no other run can read.

The store is therefore a flat ~7 GB (one entry per leg: Linux ~1 GB,
Windows ~2 GB, macOS ~0.6 GB), not a growing one. The
`hendrikmuhs/ccache-action` only installs and configures ccache; restore
and save go through `actions/cache` with one path string, because the
cache service only matches entries saved under the identical path and
the action spells it differently on Windows. A failed ccache install
falls back to an uncached build rather than failing the job.

### Precompiled header off when the cache is on

With `SLIC3R_PCH` left on, a warm cache hit only 19 % of compiles: Clang
stamps the PCH with the build time, CMake does not pass
`-fno-pch-timestamp`, and everything that includes the PCH (libslic3r
and libslic3r_gui, ~750 files) missed every run. `build_linux.sh -p`
exists for exactly this reason. The workflow now exports
`ORCA_EXTRA_BUILD_ARGS=-DSLIC3R_PCH=OFF` whenever ccache is enabled,
which brings the warm hit rate to 98.4–98.9 %.

The cost is on cold compiles, which are 25–60 % slower than today's PCH
build (ccache preprocesses every miss before compiling it, and the miss
compiles without PCH). Main pays this once after an image update or a
wide header change; PRs pay it only for the files their change
invalidates. A change to a header included by half the tree
(`PrintConfig.hpp`, `Preset.hpp`, `Model.hpp`) lands a run at 1.2–1.9×
today's time. `ccache`'s depend mode would remove the preprocessor pass
and is the natural follow-up.

### Includes the precompiled header was supplying on macOS

A build without PCH had never been tried on macOS. Three files used what
`pchheader.hpp` happened to include: `LocalesUtils.cpp` needs
`<sstream>` and `<iomanip>`, and `AmsMappingPopup.cpp` /
`PhysicalPrinterDialog.cpp` need `<wx/tooltip.h>`. libstdc++ and the GTK
wx port pull these in transitively; libc++ and the Cocoa port do not.
This is the macOS counterpart of #15552 and is worth merging on its own.

### `ORCA_EXTRA_BUILD_ARGS` pass-through

`build_linux.sh` already forwarded this variable to the slicer
configure. `build_release_macos.sh` now reads it into an array
(shellcheck-clean), and `build_release_vs.bat` appends it on both
configure lines, so CI can add a CMake option without editing three
scripts.

## Behaviour reviewers should know about

- **Main-only cache writes need `actions: write`** on the workflow token
to delete the previous entry. The default token already has it (the
nightly deploy steps write with it), so no `permissions:` block was
added. A fork PR's read-only token never reaches the delete step.
- **A runner image update cold-starts the cache** as configured, because
ccache keys the compiler by its mtime and every image rebuild reinstalls
it. Images updated 20260819 → 20260828 during this work, about every one
to two weeks. Keying on the compiler version string (`compiler_check`)
would avoid that; left as a follow-up since it changes every hash.
- **What is now the critical path:** the two Flatpak jobs (46–66 min,
untouched here), the orca-test-repo regression suite run inline in the
Linux job (7 min), and NSIS/PDB/MSIX packaging on Windows (6 min). Those
are the next wins.
- **Open question:** CI still drives `build_release_vs.bat`. #15552 gave
`build_win.bat` a `--cache ccache --no-pch` option; moving the Windows
job onto it would replace the batch-file change here.

Compile step of each build leg, minutes. Main's numbers are from run
34324625046.

| Leg | main | cold, PCH on | warm, PCH on | cold, PCH off | warm, PCH
off | ~50 % of headers changed | 5 source files changed |
|---|---|---|---|---|---|---|---|
| Linux x86_64 | 48 | ~75 | (19 % hits) | ~110 | **2.6** | 91.3 (452/928
misses) | 3.4 |
| Linux aarch64 | 41.7 | 53.4 | 52.2 (178/927 hits) | 58.8 | **2.5** |
55.8 (452/928) | 2.9 |
| Windows x64 | 57 | 85.5 | — | ~105 | **2.4** | 76.8 (449/974) | 2.5 |
| Windows arm64 | ~45 | 64.4 | — | ~78 | **4.3** | 59.6 (450/974) | 4.2
|
| macOS arm64 | 51 | ~71 | — | — | **0.8** | 79.7 (453/947) | 0.9 |
| macOS x86_64 | ~43 | 70.2 | — | — | **1.0** | 68.1 (411/742) | 1.0 |

Warm hit rates: 98.4–98.9 % on every leg; the 11–14 misses are what any
commit changes (version stamp and its includers). The "50 % of headers"
column is a real event: #15251 and #15416 merged into main between two
runs, changing 20 headers that reach 453 of 870 translation units.

Whole run, before and after (a pull-request run; wall clock to the last
non-Flatpak job):

| Job | main (run 34324625046) | warm cache (run 34444305385) | what
remains |
|---|---|---|---|
| Windows arm64 | 50.0 | 15.7 | compile 4.3, NSIS 3.5, cache save 1.6,
deps restore 1.1, cache restore 1.0 |
| Windows x64 | 67.4 | 13.2 | NSIS 3.2, PDB 2.6, compile 2.4, MSIX 0.5 |
| Linux x86_64 | 57.5 | 12.6 | orca-test-repo regression 7.6, compile
2.6 |
| macOS x86_64 | 46.9 | 6.1 | free disk space 2.3, compile 1.0 |
| Linux aarch64 | 43.9 | 4.6 | compile 2.5, apt 0.9 |
| macOS arm64 | 54.9 | 4.4 | free disk space 1.7, compile 0.8 |
| macOS universal | 7.7 | 2.2 | signing and notarisation only on main |
| Flatpak x86_64 / aarch64 | 66.6 / 46.5 | unchanged | full compile
inside flatpak-builder |
| **Wall clock** | **75 min** | **31 min** (Flatpak excluded; 66 with
it) | macOS runner queueing now exceeds job time |

Cache storage: one generation per leg is 400–680 MB compressed at PCH
on, 0.6–2 GB at PCH off; six legs ≈ 7 GB. Without the delete step, 21
main pushes a week would hold ~80 GB of entries that are never read.

## Tests

<!--
> Please describe the tests that you have conducted to verify the
changes made in this PR.
-->

- Thirteen CI runs on this PR, one change per run, with the ccache
statistics printed by every leg: cold (34336272234), warm with PCH
(34346737197), cold and warm without PCH (34352209577, 34364791732), the
macOS include fixes (34435044411, 34435968806 with `ninja -k 0` to list
every remaining file, 34439532375), all legs warm (34444305385), the
keep-only-newest cleanup (34450381312, then 34452640274 after the
Windows CRLF fix), the half-tree invalidation (34452640274), the
five-file change (34463517683, 34464720539), and this final shape
(34466377763, restore-only).
- Unit tests on all five platforms, the profile slice check, the Windows
build-script suite, Shellcheck and the universal DMG build all pass on
the cached binaries.
- The cleanup was verified against the PR's own cache scope: 44 entries
from the earlier runs reduced to exactly one per leg, on all three
platforms, after fixing the CRLF that made `gh cache delete` fail on
Windows.
- A libc++ syntax-only pass over all 1986 C++ translation units on Linux
found the `LocalesUtils.cpp` include; the two wx includes only surface
in a real macOS build and were found with a keep-going build in one
round.

HanifKoh 8d874cdc36 Register Instance Copies and Moves with Their Plate (#15613)
# Description

Each plate keeps a registry of the instances it holds
(`PartPlate::obj_to_instance_set`). The plate's filament list
(`get_extruders`), its wipe tower preview and position clamp, the object
list grouping and the saved project's per-plate instance list all read
it. Two paths left it stale:

* `Plater::increase_instances` (the `+` key / toolbar) adds the copy to
the model but never registers it with any plate.
* `GLCanvas3D::do_move` (drag release and arrow keys) ended with
`notify_instance_update(-1, 0)`, so only instance 0 of each selected
object was re-registered. Rotate, scale and mirror already notify every
instance.

So a copy created with `+` and dragged onto another plate stayed unknown
to that plate: the project saved afterwards listed it on no plate, and a
multi-filament copy moved onto a single-filament plate drew no wipe
tower there and never got its tower position clamped. The Print side
selects instances by geometry, so the plate still sliced, which is why
this went unnoticed.

This PR

* registers new copies with their plate at creation;
* has `do_move` notify exactly the instances it moved (every instance of
the object when a part was moved in Volume mode), rather than instance 0
or all instances - notifying an instance that stayed put invalidates its
plate's slice result, so `(-1, -1)` as used by rotate would have
un-sliced every plate holding a sibling copy;
* drops the registry entry again when `decrease_instances` removes a
copy.

A second commit finishes the switch #15532 started with
`contain_any_instance_totally()`: `get_extruders_without_support()`,
`check_single_extruder_mixed_filament_risk()` and
`check_compatible_of_nozzle_and_filament()` still tested instance 0
only, so an object whose copy - not its original - sits on the plate was
skipped by all three.

No new options, no format change. The `is_new` flag is deliberately not
passed for the copies: a copy landing on a spiral-vase plate gets the
same "apply spiral mode settings?" prompt a dragged instance gets,
instead of a silent rewrite of the object's settings.

## Tests

Re-run after the rebase, both binaries driven through the same headless
harness (Xvfb 1920x1080, llvmpipe) on the same fixture: `cubeA`
(filament 1) alone on plate 1, `cubeB` (a two-part object, filaments 2
and 1) alone on plate 2, so plate 1 shows no wipe tower at load. Select
the plate-2 object, press `+`, walk the copy onto plate 1 with 36 x Left
(10 mm per press, one `do_move` each), save, slice plate 1.

Before is main `8af92214d0` - i.e. with #15532's
`contain_any_instance_totally()` already in place, so the only
difference is this PR.

* **Before:** the saved `model_settings.config` lists plate 1 with
`cubeA` only and plate 2 with `cubeB` instance 0. The copy (instance 1)
is listed **on no plate at all**, and plate 1 draws no wipe tower even
though a two-filament object is sitting on it.
* **After:** plate 1 lists `cubeA` **and** `cubeB` instance 1; plate 2
still lists instance 0. The plate-1 tower preview appears, and slicing
plate 1 succeeds with the tower actually generated - the filament panel
reports 1.10 m / 0.48 m in its Tower column over 51 filament changes,
and the G-code carries `EXCLUDE_OBJECT_END NAME=cubeB.stl_id_1_copy_0`.

Same camera and fixture on both runs, so the screenshots above are
directly comparable.

HanifKoh 8af92214d0 Extract and Unify Wipe Tower Estimation (#15532)
# Description

The pre-slice wipe tower size estimate existed twice:
`Print::wipe_tower_data()` (validation) and
`PartPlate::estimate_wipe_tower_size()` (GUI placement clamp, default
placement, preview, arrange, CLI placement) — with a third partial copy
in the CLI, which resolved the brim itself around the second. They were
hand-written twins reading their inputs from different places, so
validation could measure a tower with one number after the clamp had
placed it with another.

This PR extracts the estimate into one function,
`estimate_wipe_tower_footprint()` in
`src/libslic3r/GCode/WipeTowerEstimate.{hpp,cpp}`. It takes a
`ConfigBase&` (static `PrintConfig` and GUI/CLI `DynamicPrintConfig`
both work), the filament count, layer height and tallest object height,
and returns width, depth, height and the resolved brim width.
`Print::wipe_tower_data()` and a new
`PartPlate::estimate_wipe_tower_footprint()` become thin adapters around
it; `PartPlate::estimate_wipe_tower_size()` had no callers left and is
deleted.

**Inputs made to agree** — sharing the arithmetic is not enough when
each caller derives the inputs from its own view of the model:

* **Layer height** — thinnest layer among the objects on the plate,
resolved per object (Print used the first object's, PartPlate the
preset's).
* **Objects setting the height** — `PartPlate::get_extruders` counts an
object if *any* instance is on the plate, matching `PrintApply` (it only
looked at instance 0).
* **Height per object** — per on-plate instance, from the cached convex
hull (same z extent as the mesh). `PrintObject::size()` still measures
the model's first instance, so objects whose instances differ in scale
or x/y tilt can still disagree; that is inherent to the two data
sources.
* **Wipe tower filament** — counted for every caller, since
`Print::extruders()` adds it to the tool ordering even when unused.
* **Rib width cap** — kept for both (Print lacked it).
* **Config source** — everything read from the config passed in
(PartPlate read `m_print->config()`, stale on fresh plates and in the
CLI).
* **Dual-nozzle test** — `nozzle_diameter.size()` from the config for
both.

**One decision about whether a tower exists.** The rectangle branch
sized a tower the generator never builds while the rib branch reported
none for one it does; with rib as the shipped default, a single-filament
plate that still prints a tower (custom G-code tool changes) validated
against depth 0, collapsing the collision/exclusion hull to a point. The
purge volume is computed first, and an empty footprint is returned only
when nothing is purged, there is no tool change, and nothing else puts a
tower on the plate. The reason a single config cannot see arrives as a
resolved input: validation counts `Print::extruders(true)`.

A raft is deliberately **not** one of those reasons.
`DynamicPrintConfig::normalize_fdm_2` clears `enable_prime_tower` for a
plate that purges one filament unless smooth timelapse or wrapping
detection is on, and `Print::apply()` runs it, so a raft alone leaves no
tower to reserve for. (It also keeps the tower for a single *mixed*
filament, which this does not model — `Print::extruders(true)` does not
expand mixed filaments.)

**Two implementation notes:**

* Enums are read **by value**: a preset-built `DynamicPrintConfig` holds
`ConfigOptionEnumGeneric`, so a `dynamic_cast` to `ConfigOptionEnum<T>`
is null for exactly the config the GUI and CLI pass. The tests build
their configs the way `PresetBundle::full_config()` does, so that
storage is what gets tested.
* `PartPlate::estimate_wipe_tower_footprint()` is CLI-reachable, so
`get_extruders(bool)` gained a config-taking core with the identical
body; the GUI wrapper passes the app's presets, the adapter passes the
config it is given. `get_extruders_under_cli()` was not substituted: it
filters the plate's instances differently (skips unprintable ones, keeps
ones the plate flags as outside), so the GUI's filament set would have
changed in edge cases.

**Also fixed here:** `WipeTowerData` carries the effective width — set
by the estimate, and then by both planners at generation, so it never
disagrees with its neighbour `depth`; the preview and the containment
check take *whether there is a tower at all* from the footprint instead
of each re-deriving it; the config-taking `get_extruders` answers for an
object-less (`.gcode.3mf`) plate the way the wx overload does; the
preview takes body *and* brim from the plate's own footprint (an auto
brim drew every plate with the selected plate's brim);
`estimate_wipe_tower_polygon` builds its margin from the resolved brim
("Auto" gave a margin of 0) and no longer calls `std::clamp` with `hi <
lo`; the estimate falls back to declared defaults instead of hand-copied
constants. `estimate_wipe_tower_size()` /
`estimate_wipe_tower_polygon()` lose four parameters every caller took
from the same config.

## Behaviour changes reviewers should know about

G-code is never affected; no 3MF, profile or string changes. But this is
**not** a pure refactor:

1. **Validation now reserves what the placement clamp reserves**, which
is in places larger than before. A saved 3MF with a tower close to an
exclusion area or the rear edge can be rejected where it previously
sliced; dragging resolves it since the clamp agrees. Nothing re-clamps a
stored position on load (out of scope; the CLI side lands with #15518).
2. **`PartPlate::get_extruders` counts any-instance-on-plate**, which
reaches every caller of it, not only the estimate. It is `PrintApply`'s
rule and closes a GUI/CLI divergence.
3. **`estimate_wipe_tower_polygon`'s rear/right bound is looser by one
brim width** (it subtracted the brim twice).
4. **A single-filament plate with a rib wall no longer reserves a
phantom tower.**
5. **A single-filament plate whose tower comes from wrapping detection
is now validated against the bed.** Neither the old estimate (which read
only the wall type and smooth timelapse) nor the old containment gate
(the filament count or smooth timelapse) knew about that tower, so
between them it was never checked. It is printed, so it can be rejected
now.

Not addressed: the estimate still does not read `wipe_tower_type` or
per-filament `filament_prime_volume`, inherited unchanged from both
copies (the generated Type 1 tower is ~10 mm larger than the estimate on
Bambu profiles). #15516 mirrors the planners and folds into this
function on rebase.

## Verification

Before/after on the same fixtures with a main build and this branch, all
numbers read from the CLI (details, method and the real-tower and
arrange-clamp tables in the first comment):

| Fixture (divergence) | Side | Before (w × d, mm) | After (w × d, mm) |
|---|---|---|---|
| control | GUI/CLI · validation | 23.585 × 23.585 · 23.585 × 23.585 |
same |
| per-object layer 0.1 | GUI/CLI · validation | **23.585** · 31.637 |
**31.638** · 31.637 |
| unused `wipe_tower_filament` | GUI/CLI · validation depth | **39.332**
· 44.542 | **44.541** · 44.542 |
| tall object, instance 0 on another plate | GUI/CLI · validation |
**23.585** · 29.391 | **29.390** · 29.391 |
| rib cap binds | GUI/CLI · validation | 11.170 · **13.910** | 11.170 ·
**11.170** |

Before, the two estimates disagree on every divergence fixture; after,
they agree to the 0.001 mm bisection resolution, the control is
unchanged, and G-code is byte-identical. GUI screenshots of the preview
on both binaries are in the same comment.

The table was measured on the first commit; none of its fixtures uses a
raft or a zero purge volume, so the second commit does not move them.
G-code equivalence was re-checked on the final tip: `Cube.3mf` sliced by
a `main` build and by this branch is byte-identical.

**Per-object layer height reaching the preview.** One object with a 0.1
mm override against a 0.2 mm preset. `main` sizes the previewed tower
from the preset, so it is smaller than the one validation reserves and
the one that prints; this PR sizes it from the object. Captured
headlessly on both builds from the same project, top view:

<img width="1408" height="596" alt="D_per_object_layer_height"
src="https://github.com/user-attachments/assets/989920fc-9f14-4658-8a3d-681c92a7f754"
/>

Measured over the four evidence fixtures on both builds, this is the
only one of the corrected inputs that changes what is drawn: the others
(an object contributing through a non-zero instance, an unused
`wipe_tower_filament`) change the estimate by amounts confirmed through
the CLI bisection above, but leave the rendered tower pixel-identical.
Arrange is unaffected either way — the tower enters the arranger as a
fixed obstacle (`m_unselected`), so it never moves.



## Tests

* `tests/libslic3r/test_wipe_tower_estimate.cpp` (10 cases / 104
assertions): rectangle and rib sizing, stability floor and auto brim,
single-filament cases (timelapse, wrapping, and a raft *not* reserving
one), a tool change reserving the floor when the purge volumes resolve
to zero, both wall types agreeing on tower existence, dual-nozzle
volume, the shipped flush-matrix path, default fallback for a missing
key, and a {rectangle, cone, rib} × {type1, type2} matrix asserting a
preset-shaped `DynamicPrintConfig` and a static `FullPrintConfig` give
the same footprint.
* `tests/fff_print/test_wipe_tower.cpp`: what `Print` feeds the
estimator — thinnest object layer height, effective width reaching
validation, the width staying current through generation, a
single-filament plate reserving a tower only when one is really printed
(raft no, smooth timelapse yes), and a wrapping-detection tower being
bed-validated. The last two fail on `main` and on the first commit of
this PR.
* Full suites green on this branch: `libslic3r_tests` 342 cases / 58325
assertions, `fff_print_tests` 174 cases / 3152 assertions. `--target
all` builds clean (including `OrcaSlicer_profile_validator`, which needs
`-DORCA_TOOLS=ON`). No new warnings.
* CLI evidence run above; its unused-`wipe_tower_filament` fixture is
also the regression check for the adapter under the CLI, which no unit
test can reach (`PartPlate` needs a GL context).

HanifKoh 8a291f9d56 Confine config import to the preset directory (#15608)
import_presets reduced each zip entry to a basename by stripping only
'/', so on Windows an entry named with '\' separators kept its
directory components and was extracted wherever they pointed. Strip
both separators, and reject any entry whose name still escapes the
extraction folder.

The preset name from the JSON and the bundle id from
bundle_structure.json were joined onto the preset directory unchecked
as well, which let either of them write outside it on every platform.
Both are now validated before anything is written.

The check is the is_path_within_root helper the 3MF importer already
had, moved to Utils so both importers share it. It treats '/' and '\'
as separators on every platform, so a bundle that would escape on one
OS is rejected on all of them.

HanifKohandraistlin7447 4deadc9dce Make Tree-Support Deterministic (#15565)
* Make tree support deterministic without giving up its parallelism

* Break equal-distance ties in the tree support MST by coordinates

* test: cover the determinism this PR fixes

The MST unit tests here cover the tie-break, but the drop_nodes rework
has no test.

Adds two cases to the tree support suite. The thread-scheduling one
slices five configs twice each and compares the support point sequence,
which is what the node ordering moves. The MST tie one pins the branch
diameter and line width that carry Prim's equal-distance ties into the
toolpaths.

slice_with_tree_support takes an optional config list so the second case
can add the tree parameters it needs, and the double-slice comparison is
shared rather than written twice.

Both fail on main without this PR. The first passes from 60d1ceb580, the
second from e148865dd6.

HanifKoh 58bf267fdd Scale Min Junction Width to Prevent Fuzzy Skin From Failing Slice (#15566)
* Fix fuzzy skin failing the slice: the minimum junction width was unscaled

* Unit Tests For Fuzzy Fix

* Cover ridged multifractal noise in the fuzzy skin width floor test

Its output is not bounded to [-1, 1], so it scales past the configured
thickness and drives the junction width negative. The floor has to hold
for any noise value, not just an in-range one.

HanifKoh 8e064659ad Fix Non-Deterministic Slicing - Order Per-Layer Intersection Lines Canonically (#15563)
Fix nondeterministic slicing: order per-layer intersection lines canonically

Facet processing in slice_make_lines() is parallel, so the per-layer line
order depended on thread scheduling. make_loops() consumes that order for
island order and loop start vertices, so the same model could slice to
different G-code run to run.

Sort each layer's lines by a topology-based key. edge_type and flags are
appended to the key purely to break ties: two lines can share every id and
endpoint (a Horizontal facet can emit such a pair) and std::sort is not
stable, so without them that pair's order would stay thread-dependent.

HanifKoh c61d2fe5d1 Fix the Folgertech i3 0.6 nozzle printable area (#15577)
The bed was declared as 0x0, 20x0, 200x200, 0x200 - a triangle - where the
0.4 nozzle profile and the printer have the 200 x 200 square. Found by the
profile validator once it placed the prime tower beside the test cube:
no tower fits inside that outline.

HanifKoh df30e22427 [CLI]: CLI Crash Guards (#15477)
# Description

<!--
> Please provide a summary of the changes made in this PR. Include
details such as:
  > * What issue does this PR address or fix?
  > * What new features or enhancements does this PR introduce?
> * Are there any breaking changes or dependencies that need to be
considered?

Part 1 of 3 of the CLI-mode bug sweep, split out of #15452 per review
feedback there. This PR contains the crash fixes.

## Fixes

- **`--outputdir`/`--datadir` with a missing parent directory aborted**
via unguarded `create_directory`. Directories are now created
recursively, with a graceful early exit and a specific error message if
creation fails.
- **`--slice` + `--export-3mf` segfaulted on a from-scratch slice**:
`ConfigOptionVector::get_at()` on an empty vector is `.front()` of an
empty vector (UB). Guards added for `filament_color`/`filament_id` at
the CLI call site, and inside `DynamicPrintConfig::get_filament_type`
for `filament_type`/`filament_is_support`/`filament_id`. Only *empty*
vectors are treated as missing — the existing clamp-to-front behavior
for merely out-of-range indices is preserved, so GUI callers are
unaffected.
- **OOB heap write from stale `filament_self_index` on
`--load-filaments`** (fixes #14181): a 3MF carrying more
`filament_self_index` entries than loaded filaments wrote past the end
of `old_variant_counts`. The guard validates both bounds — entries `>
filament_count` *and* non-positive entries (`< 1`), since a single `0`
in an otherwise-valid array indexes `old_variant_counts[-1]`.
- **Wrong printable-area check** for non-rectangular beds: use the
printable area's bounding box instead of a naive vertex calculation
(fixes #15363).
- **`nozzle_height` and `align_center` were not read into the arrange
config** in CLI mode.
