Since #15438, every CLI run that loads a system preset spends about a
second per preset file re-parsing that vendor's entire profile tree. A
slice with a machine, process and filament preset got roughly 2.5 s
slower, and a four-filament slice roughly 4 s slower. This PR loads each
vendor tree once per run instead. Resolved presets and G-code are
unchanged.

The GUI never takes this path, and no release contains #15438, so the
regression only affects CLI runs on current dev and nightly builds. That
includes print farms, slicing services and plugins that call
`orca-slicer --slice`, and CI suites.

## Changes

### Why it was slow

`PresetBundle::resolve_preset_config` resolves a system preset through
its vendor manifest by loading the whole OrcaFilamentLibrary bundle and
the whole vendor tree from JSON, then picking the one preset out. The
CLI did that separately for every `--load-settings` and
`--load-filaments` file, on a fresh `PresetBundle` each time. With BBL
presets, a machine + process + filament run opened `BBL.json` three
times and read BBL's 2,879 profile files and the library's 512 three
times over.

### Load each vendor tree once

- `PresetBundle` keeps every vendor bundle its manifest path loads,
keyed by source root, vendor and substitution rule, and reuses them for
later resolutions on the same bundle.
- OrcaFilamentLibrary is cached the same way, so vendors under one root
share a single library load and the library's own presets resolve from
that same instance. A vendor bundle only reads from its base while
loading, so sharing it is safe.
- A failed or throwing load is not kept, so error reporting is
unchanged.
- The key includes the source root, so presets from two different
profile roots still resolve separately.
- The CLI resolves every system preset through one `PresetBundle` for
the whole run, instead of creating one per file.

The resolved configurations still come from the same canonical vendor
loader, so what a preset resolves to does not change. Only the CLI calls
`resolve_preset_config`, so a long-lived GUI bundle cannot end up
holding profile trees that later change on disk.

CLI slice of a 20 mm cube with X1 Carbon system presets. Both builds get
the same datadir, best of 3, Linux. "Before" is this PR's base from CI.

| System presets loaded | Before | After |
|---|---|---|
| machine | 0.95 s | 0.87 s |
| machine + process | 1.67 s | 0.92 s |
| machine + process + 1 filament | 2.51 s | 0.97 s |
| machine + process + 4 filaments | 5.00 s | 0.99 s |

Files opened during the machine + process + filament run (`strace -e
openat`):

| | Before | After |
|---|---|---|
| `BBL.json` | 3 | 1 |
| `OrcaFilamentLibrary.json` | 3 | 1 |
| `system/BBL/**/*.json` | 8,634 | 2,880 |
| `system/OrcaFilamentLibrary/**/*.json` | 1,536 | 512 |

Peak memory did not rise: max RSS 306 MB → 286 MB for the three-preset
run, and 305 MB → 285 MB for four filaments. The "before" figure is an
AppImage, so part of that gap is probably packaging.

## Tests

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

- New test "Manifest-backed resolution reuses the vendor tree it already
loaded" in `tests/libslic3r/test_preset_bundle_loading.cpp`. It resolves
one preset, changes the parent profile on disk, then resolves a sibling.
The same bundle returns the value it already loaded, and a fresh bundle
picks up the change.
- New test "Manifest-backed resolution shares the library between
vendors under one root". It resolves through one vendor, changes a
library profile on disk, then resolves through a second vendor and a
library preset on the same bundle. Both return the value already loaded,
and a fresh bundle picks up the change.
- All `[Preset][Bundle]` tests pass (87 test cases, 1,069 assertions),
including the existing manifest-backed resolution cases for source-root
scoping, malformed vendor loads, missing parents and type mismatches.
- G-code of the three-preset slice is identical before and after, header
lines excluded.
- The external CLI regression suite passes. Two cases report as
unexpectedly passing because #15639 fixed their bug. They pass the same
way on this PR's base without the change.
- A GUI-vs-CLI parity run over 10 fixtures shows no new differences.
- Builds clean on Linux (Release, with tests).

Hanif Koh d5cf1502c4 Share One Library Load Between Vendors in the CLI Preset Resolver
The manifest resolver loaded OrcaFilamentLibrary once per vendor it
resolved through, so a run that mixes vendors parsed the library tree
again for each of them. The library is now cached like any other vendor
tree, keyed on its root and substitution rule, and doubles as the base
every vendor under that root loads against. A vendor bundle only reads
from its base while loading, so sharing the instance is safe.

The cache key carries the substitution rule as its enum, and the lookup
lambdas take a const bundle since they only read.

HanifKoh 37e2b6c928 CLI: let --export-settings - write the merged config JSON to stdout (#15698)
`--export-settings` already writes the merged config as JSON at the
right point in the CLI flow. Passing `-` now writes that same document
to stdout, so scripts can inspect the effective config without a temp
file. This replaces #14605.

- `ConfigBase::save_to_json` gains a stream overload. The file overload
serializes through it before opening the file, so the output format is
unchanged, and a config that cannot be serialized (invalid UTF-8) now
leaves the existing file untouched instead of truncating it.
- On stdout, invalid UTF-8 in string values is written as U+FFFD instead
of ending the process with an uncaught `type_error`. Files keep the
strict behaviour.
- To keep stdout pure JSON, `-` is rejected up front (stderr message,
`CLI_INVALID_PARAMS`, shell status 254) when combined with an action or
transform that can write to stdout or does real work: `--info`,
`--help`, `--orient`, slicing and exporting. Options that do nothing
without a slice (`--uptodate`, `--min-save`, `--pipe`, ...) are still
accepted.
- The one unconditional stdout write on a success path, "skip locked
instance" during arrange, now goes to the log.
- Every other value, including the default `output.json`, behaves as
before.

Tests in `tests/libslic3r/test_config.cpp`: the stream output equals the
file output and keeps the tab-indented format; invalid UTF-8 throws on
the strict path and is replaced when asked; a failed save leaves the
previous file intact.

Kris Austin efc9f253ee fix: resolve relative input paths given on the command line (#14803)
Opening a model with a relative path, for example `orca-slicer ./some.3mf`,
failed with "Loading of a model file failed." and "The file does not contain
any geometry data.", while the same file opened by an absolute path or by
drag and drop worked.

GUI_App::init_app_config() changes the working directory to <data_dir>/log,
and it runs from the GUI_App constructor because the app config is needed
early for instance checking. The input files are opened much later, in
post_init(), so a path still relative at that point resolved against the log
directory instead of the directory OrcaSlicer was started from, and the 3MF
reader failed to open it.

Resolve the input paths in CLI::setup(), which runs before GUI_App is
constructed and therefore before the working directory moves. Absolute paths
are returned unchanged, so the forms that open today are unaffected, and
custom open protocol URLs are passed through since post_init() hands those to
the downloader rather than the file loader.

The working directory change is left alone. It was added in #3248 so the TUTK
logs land in the data directory instead of the working directory (#3209).

Daniel Williams 70247ad298 Extract Layer::choose_ironing_extruder for unit-testable ironing routing (#13467)
* Extract Layer::choose_ironing_extruder for unit-testable ironing routing

The ironing extruder selection in make_ironing() was a 5-line nested
conditional inlined at the top of the loop, with no isolated test
coverage. Pull the gating into a static helper so the routing decision
is unit-testable without spinning up the slicing pipeline.

Pure refactor: the helper preserves the original logic bit-for-bit
(NoIroning -> -1; AllSolid always enabled; TopSurfaces and TopmostOnly
require some top shells or, in spiral mode, more than one bottom shell;
TopmostOnly additionally requires being on the topmost layer; enabled
ironing routes to solid_infill_filament).

Add tests/fff_print/test_choose_ironing_extruder.cpp covering:
- AllSolid regardless of layer position
- TopSurfaces with top_shell_layers > 0
- TopSurfaces with top_shell_layers=0 + spiral mode + bottom_shell_layers>1
- TopmostOnly + topmost layer
- NoIroning short-circuit
- TopSurfaces with top_shell_layers=0 (and not spiral) -> disabled
- TopSurfaces, spiral, but bottom_shell_layers=1 -> disabled
- TopmostOnly on a non-topmost layer -> disabled

* Move ironing routing test into the Fill subsystem file

Rename the test to tests/libslic3r/test_fill.cpp and tag it [Fill] to
match the subsystem it covers, use flat behavioral test cases with
GENERATE for the parameterized ones, and drop the history narration from
the code comments.

* tests: move ironing routing tests into fff_print/test_fill.cpp

Keeps the Fill tests in one file, alongside the existing ironing
rotation-template test.

Hanif Koh d4840901fc Test That Failed Vendor Loads Are Not Kept and the Library Base Is Reused
Cover the two cache paths the first test left open: a vendor tree that fails to load is retried on the next resolution instead of being served from the cache, and a type-probed filament resolved through resolve_preset_config_type reuses the OrcaFilamentLibrary base already loaded for a sibling.

Hanif Koh 5f01f21661 Load Each Vendor Tree Once When the CLI Resolves System Presets
Resolving a system preset through its vendor manifest loaded the whole vendor tree and the filament library from JSON, and the CLI did that separately for every --load-settings and --load-filaments file. A run with machine, process and filament presets parsed BBL's 2,879 profile files and the library's 512 three times over, about a second each.

Keep the library and vendor bundles loaded by the manifest path on the PresetBundle that resolved them, keyed by source root, vendor and substitution rule, and have the CLI resolve every system preset through one bundle for the whole run. A failed load is not kept, so errors are reported as before.

On a cube slice with X1C machine, process and PLA presets: 2.42 s -> 0.93 s, BBL.json opened once instead of three times, identical G-code.

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.

Valerii Bokhan e8d35fadd4 Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill (#15206)
* Fix internal bridges over Hilbert Curve/Octagram Spiral sparse infill

For patterns with curved/turning anchor lines (Hilbert Curve, Octagram
Spiral), the bridge_over_infill algorithm produced incorrect results:

1. determine_bridging_angle: sampling curved anchor orientations
   produced noise across all turning directions (0/90/180/270°)
   instead of a single dominant one, yielding unstable bridge angles
   with 180° spread. Fix: use the configured infill_direction + 90°
   directly, bypassing the noisy sampling. The old blind +0.25*PI
   (Hilbert) and +1/16*PI (Octagram) offsets are removed.

2. construct_anchored_polygon: curved Hilbert/Octagram anchors
   intersected each vertical scan line many times at wildly different
   Y positions, producing chaotic polygon sections — holes in random
   places, bridges over air, rotated bridges. Fix: replace the curved
   infill polylines with synthetic straight lines parallel to
   infill_direction, spaced at the real infill line spacing
   (flow_spacing / density). Lines are centered on the limiting_area
   bbox center so that after rotation they span the full bridged_area.
   Anchors are left at full bbox length (not clipped) to guarantee
   every scan line finds an anchor.

Rectilinear and other straight-line patterns are unaffected.

Known limitation: some bridge edges may still terminate over air in
edge cases where the nearest synthetic anchor line is more than one
infill spacing away from the bridge boundary. This will be addressed
in a follow-up.

* fix: anchor internal bridges to actual sparse infill

Preserve real anchors across regions and align plane-path anchor origins with printed infill. Respect lower-layer rotation templates and model alignment, and sample curved bridge boundaries more finely.

Add regression coverage for anchor alignment, bridge angles and region isolation, with Orca comments explaining the geometry constraints. Verified 175 FFF tests before the comment-only follow-up; preserve CRLF in modified files.

* Fix internal bridge support contacts and separated infill origins

Restore anchor contact after bridge smoothing and share per-body pattern origins between anchors and printed infill. Recompute origins when preparation settings change.

Cover multiline counts 1, 2 and 3 and add regressions for printed bridge support, separated infill alignment and reslicing.

* Add explicit standard headers to PrintObject tests

* test: cover surface centering when infill settings change

Verify top and bottom Archimedean Chords and Octagram Spiral paths after switching centering modes or toggling separated infills. Compare reslicing against fresh slicing and document dependent infill invalidation.

* test: preserve directional surface infill when settings change

* perf: index layer islands for connected-body detection

* test: use public print pipeline for body centering checks

Kris Austin 7888452666 build: clear 7 warning categories across 26 sites (#15615)
* build: clear 2 warnings - cast the NSTextField the class check already proved

mainframe_text_field is NSTextField* and was assigned a bare NSView*, which
Clang reports as -Wincompatible-pointer-types. Both assignments sit inside
if ([viewObject class] == [NSTextField self]), so the runtime type is already
guaranteed, and the line above the second one casts the same variable the same
way to call setTextColor. macOS only, since nothing else compiles this file.

* build: clear 6 warning categories from the clang-cl inventory

-Wmissing-braces (9). Aggregates whose first member is itself an aggregate.
GUID's fourth member is BYTE[8], so the trailing eight bytes take their own
braces. The others were reaching for zero-initialization with {0} and say {}
now. bbs_3mf's backup Task ends in an anonymous union, which needs braces of
its own; those braces initialize the union's first member rather than the one
named at the call site, so the RemoveBackup site says so in a comment.

-Wmacro-redefined (11). SendMultiMachinePage.hpp defines five names that
Preferences.hpp, PresetBundleDialog.hpp, ExportPresetBundleDialog.hpp and
TroubleshootDialog.hpp also define with different values, so the value in
force depended on include order. All nine of this file's DESIGN_ macros take
the SEND_ prefix it already uses for its own macros, values unchanged, so a
DESIGN_ name added elsewhere later cannot collide with it again. They read as
one page-local palette, a 900 to 400 gray ramp plus sizes, so the four with
no current readers stay: dropping them would leave gaps in a named scale. test_marchingsquares.cpp defines NOMINMAX,
which libslic3r already passes as a PUBLIC compile definition, so it takes
the #ifndef guard the other suites use.

-Wbraced-scalar-init (3). Two PushStyleVar calls resolve to the float
overload, so the braces were initializing a scalar. ConfigOptionFloatsNullable
already takes an initializer_list, so the inner braces did the same thing.

-Wmicrosoft-goto (2). Both gotos in copy_file_gui jump forward over the
initialization of size, dwRead and dwWrite, which only MSVC accepts. Those
declarations move up to join the others at the top of the function.

-Wunused-private-field (3). Every use of ColourPicker's m_clrData and
m_picker_widget is behind !defined(__linux__), so on Linux they are written
and never read; the members now carry the same guard. ParamsPanel's
m_size_move is read nowhere. Tab has its own, which is the one Tab.cpp uses.

-Wnonportable-include-path (2). BaseException.h asked for "stackwalker.h"
and the file on disk is StackWalker.h.

Kris Austin fa3dbfcc6f fix: clear 1 warning - report the real error when a Windows G-code export fails (#15582)
fix: report the real error when a Windows G-code export fails

copy_file built its failure message as "Error: " + errCode. Adding a DWORD
to a string literal is pointer arithmetic, not concatenation, so the pointer
lands errCode bytes into an 8-byte literal and runs past its end for any code
above 7. std::string then calls strlen on it and throws length_error, and the
catch(...) in BackgroundSlicingProcess::finalize_gcode replaces the diagnosis
with "Unknown error occurred during exporting G-code."

Every code a user is likely to hit is past the end: write-protected media is
19, no media 21, a full disk 112, and a destination held open by another
program 32. Codes 1 to 7 stay inside the literal and produce a truncated
message instead. So the "Maybe the SD card is write locked?" text has not
been reachable on Windows since this path was added in #2923.

Now that it is reachable, that guess only fits removable media, so it is
conditional on m_export_path_on_removable_media. The existing string is
untouched and keeps its 23 translations; the fixed-drive case adds one string.

Hanif Koh 2f2a6bc3b5 Share the Estimated First-Layer Outline of the Wipe Tower
The preview brim, the placement margin and the pre-generation validation
warning each decided on their own whether the tower has a Type2 cone
base, reading the wall type and cone angle three different ways. The
preview's read cast the preset's enum to ConfigOptionEnum<T>, which a
preset-shaped config never holds, so the cone base was never previewed.

estimate_wipe_tower_first_layer_outline now answers that question once,
beside the footprint estimate, from the config and the resolved planner;
all three sites take the outline from it. The libslic3r case reads the
outline off a preset-shaped config, where the old cast came back empty.
2026-09-09 15:45:16 +08:00
Hanif Koh 81357695c5 Verify WipeTower Footprint at Point of Generation
The clamps and validation work from estimates. Once the tower is
generated, _make_wipe_tower re-tests the exact first-layer footprint,
brim and cone base included, against the printable area and the
exclusion zone, so an off-plate tower fails with a clear error instead
of exporting unprintable G-code. The rectangle-wall mesh footprint
learns the Type2 cone base so that check and the post-generation
validation see the real outline.

Pre-generation, validation hard-checks the body plus an explicit brim
and warns on the estimated auto brim and cone base with the existing
"may collide" strings, so the user hears about a marginal position on
the first slice rather than only at generation time.

Two fff_print fixtures that print a tower at the default position move
it onto the 200 mm test bed, as the multifilament fixtures already do:
the shipped default y of 220 is off that bed, and the backstop now says
so instead of exporting the tower.

Hanif Koh 2fdc16f9f2 Size a no-purge tower at the planners' idle depth
Smooth timelapse no longer charges a prime volume it does not purge. A
tower printed with no tool change is exactly the idle depth: the
stability minimum for Type2, the wrapping detection depth for Type1.
Charging a full prime_volume on top made the previewed and arranged
tower deeper than the one that is printed.

The Type2 half of "a tool change reserves a tower whatever the purge
volumes resolve to" arrives with the base commit; here it only has to
survive the planner split, since Type1 already reserves per filament.

The wipe tower filament only joins the tool ordering when there is a
tower to join, which is the has_wipe_tower() half of the guard
Print::extruders applies.
2026-09-09 15:45:16 +08:00
Hanif Koh 99627c8e93 Size the Footprint Estimate from the Planners
The shared estimate reserved every tower with one volume-per-purge rule
and the stability floor. Both planners do more: WipeTower (Type1) wipes
each filament's own prime volume in whole lines, one block per
adhesiveness category sized by its worst layer, rams the leaving
filament at every nozzle change, and squares a rib tower from the
planned depth; WipeTower2 (Type2) spaces its lines by
wipe_tower_extra_spacing, not the Type1-only infill gap, and its extra
flow cancels out of the depth. Both extend the ribs rather than the body
below the stability minimum, size every layer including a thinner first
one, and lay the brim in whole loops, WipeTower reporting half a spacing
of line width on top.

All of that now lives in estimate_wipe_tower_footprint, fed the planner
(resolve_wipe_tower_type mirrors Print::wipe_tower_type and the CLI's
Bambu Lab detection) and the filament ids rather than a count. Print
passes its own tool set; the PartPlate adapter derives the plate's ids
from the passed config and treats an explicit count as a floor, so the
CLI's count-only callers size per filament too. The placement clamp also
reserves a Type2 cone's base bulge, which the body box does not cover.

The planner-mirroring helpers sit beside the planners in WipeTower and
WipeTower2 so the two stay in sync; the libslic3r cases pin them to
footprints measured from generated G-code.
2026-09-09 15:45:16 +08:00
Hanif Koh e1efec7d6c Fix review findings in the shared wipe tower estimate
A raft is not a reason to reserve a tower. Print::apply runs
normalize_fdm_2, which clears enable_prime_tower for a plate that purges
one filament unless smooth timelapse or wrapping detection is on, so a
single-filament plate with a raft prints no tower at all and the estimate
was reserving bed area for one. Drop the input; need_wipe_tower is now
exactly the two exceptions normalize_fdm_2 honours, named there so the
next reason added has to be checked against it.

The GUI preview and the validation containment check each re-derived
"is a tower printed here" from the filament count instead of reading the
estimate, so both missed the towers printed with no tool change to purge
for. They now take the answer from the footprint, which is the drift this
shared estimate exists to remove. A tower that is not printed estimates to
zero, so its hull is degenerate and every check on it passes trivially -
the containment check needs no gate of its own.

WipeTowerData::width was written only by the pre-generation estimate and
left at zero for the whole post-generation life of the Print, while its
neighbour depth held the real value. Set it from the generator in both
branches.

The plate's height scan transformed every model part's full mesh per
instance on each scene reload, discarding all but the z extent. The
cached convex hull has the same z extent.

A plate loaded from a sliced .gcode.3mf holds no objects and its filaments
live in slice_filaments_info; the config-taking get_extruders overload
returned an empty list for it, which sized the tower for a placeholder two
filaments. It now answers the way the wx overload does, without reaching
the plater.

Also drop estimate_wipe_tower_size, which has no callers.

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.

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.

SoftFever 4aa0e1d60b Translate filament ids at the printer boundary
Orca content-addresses every system filament, Bambu's included, but a printer,
its AMS and its vendor's cloud know only that vendor's own catalog ids. The
printer agent now translates between the two: outbound MQTT and FTP traffic, the
AMS mapping sent with a print job, and the ids written into a 3mf bound for the
printer all leave in the printer's own ids, while status messages, loaded
projects and SD-card prints arrive in Orca's. An id with no mapping passes
through unchanged, and an agent whose printers already speak Orca's ids
translates nothing at all.

Bambu's map is generated from BambuStudio's own shipped bundle; a missing or
unreadable file leaves every lookup an identity rather than taking the app down.
The profile check validates the map's shape, and profile CI now runs on the paths
that can change it. docs/HLSD/filament_id.md records the places the map
deliberately does not reach.

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

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.
