maziggy 9a837d19a1 fix(slicer): strip zero-valued filament-index sentinels, and sanitise the preview slice too (issue #3030)
Bambu Studio writes 0 into wall_filament, sparse_infill_filament and
solid_infill_filament to mean "use whichever filament the object is set
to". Bambu Studio and OrcaSlicer 2.4 define these min 0 and accept it;
OrcaSlicer 2.3 and earlier used the 1-based scheme (min 1, default 1)
and reject it with "0 not in range [1.000000,...]". Sidecar images are
version-tagged, so an install can be pinned to one of those builds.

Same shape as the -1 inherit markers from #1201 with a different marker,
so the allowlist becomes a key-to-marker map rather than one global
constant. The buckets must not bleed: a -1 on a filament index is a real
value, and a 0 on a raft field is a setting the user chose.

The key is removed rather than rewritten, which is what makes it safe on
every build. The CLI then uses its own default: 0 where 0 was legal
(unchanged), 1 on the older builds, which is what "the active filament"
means under that scheme.

The preview slice never ran the sanitiser at all, so a file that sliced
fine could still fail its automatic plate preview and fall back to the
painted-face heuristic. It matters more there than in a real slice: the
preview runs on the file's own embedded settings, so there is no
--load-settings pass that could supply a replacement for a field the
range validator has already rejected. That also explains the reported
"same error on a later attempt of an unchanged file" without any second
copy of the keys -- the validator that emits it reads the merged global
config, which per-object model_settings.config overrides never reach.

The sanitiser moves to utils/threemf_tools so the service can use it
without importing a route module, and both preview callers pick it up
from one place. Drops _strip_3mf_embedded_settings and its constant,
which have had no callers since the strip-everything experiment was
reverted.

maziggy 15ea11e10b Recover the preview slice from custom G-code the sidecar cannot parse
Opening the slice dialog on an unsliced project runs a preview slice purely
to ask the slicer which AMS slots the chosen plate consumes. Bambu Studio 2.8
writes {if timelapse_inline_photo} into the machine's time_lapse_gcode but
exports no definition for that variable, so the template is unresolvable the
moment it leaves Studio: an older sidecar stops with a placeholder parse error
before producing any slice_info. The preview returned nothing and the caller
fell back to guessing from painted faces, silently. On the H2D project this
was found with, the guess dropped the support material -- a whole slot off a
four-filament plate.

Retry the preview once with just the named template emptied, still on the
file's own settings. Keeping the embedded settings is what keeps the answer
honest: overriding the process preset instead discards the project's support
configuration, which loses that slot and moves used_g by up to 2x. Measured
against the same file: retry reproduces all four slots gram for gram, a
printer+process override returns three.

Only templates that cannot extrude are eligible -- a start or filament-change
template lays a prime line or purges, so emptying one would move the very
grams the preview reports, and returning nothing beats a confident wrong
number. Verified on a working H2D slice that emptying time_lapse_gcode leaves
every used_g/used_m in slice_info identical.

Match on a normalised option name: the slicer reports timelapse_gcode while
the 3MF stores time_lapse_gcode, so a literal comparison finds nothing.

Decide whether a retry applies before logging, so a slice that recovers does
not announce itself at WARNING twenty seconds before it succeeds.

maziggy 1c42a9f1fd remove(slicer): drop bundle import; fix cloud preset type/from for CLI (#1712)
Bundle import never delivered what it implied: BambuStudio's .bbscfg export
  strips system processes/filaments, so importing a bundle left users without
  process presets and slicing fell back to embedded settings on STL. Bundle
  mode also hid the standard tier behind a constrained dropdown, the actual
  trap reported here.

  Removed end-to-end:
  - backend: POST/GET/DELETE /slicer/bundles*, SliceRequest.bundle,
    SliceBundleSpec, dispatch fork in library.py, bundle-context params on
    the filament-requirements endpoints, bundle-fingerprint cache key in
    slice_preview.py, SlicerApiService.{import,list,get,delete}_bundle and
    slice_with_bundle, BundleSummary / BundleNotFoundError.
  - frontend: BundlePicker + BundleStringDropdown, isBundleMode + every
    branch, bundle state/queries/dispatch in SliceModal.tsx, SlicerBundle /
    SliceBundleSpec types, three bundle API methods. buildCompatibilityIndex
    loses its bundle path; presetCompatibility keeps compatible_printers
    plus the @BBL fallback.
  - SlicerBundlesPanel turns into a permanent static notice explaining the
    removal, alternative import paths, and the new slice-time lookup order
    (Imported > Orca Cloud > Bambu Cloud > Standard sidecar fallback).
  - i18n: slicerBundlesRemoved.{title,description,alternatives,lookupOrder}
    translated across all 11 locales; slice.bundle*, slicerBundles.* keys
    removed.

  Fixed (surfaced by removing bundle mode):
  - _resolve_cloud and _resolve_orca_cloud now force type per slot and pin
    from: "system" on the payload before json.dumps. Bambu Cloud ships
    type as "printer"/"print" and routinely empty `from`; the BS CLI's
    --load-settings parser rejects both with return -5 / "input preset
    file invalid". Standard tier already did this; cloud paths now match.

maziggy 8a31397171 feat(slicer): bundle-aware preview slice for accurate gram estimates
The SliceModal's preview slice runs against unsliced project files to
  discover per-plate AMS slot consumption. Until now it always used
  slice_without_profiles — accurate slot mapping (a model property) but
  gram numbers were derived from the file's embedded process settings,
  which can drift from the triplet the real print will use.

  When the caller provides a bundle id + printer/process/filament preset
  names, get_preview_filaments now routes through slice_with_bundle so
  the preview's gram numbers match what the real print will produce.
  Cache key picks up a bundle-context fingerprint so different bundle
  picks on the same file occupy distinct entries.

  Backend:
  - slice_preview.get_preview_filaments: optional bundle_* params
  - library.py + archives.py: forward params via /filament-requirements

  Frontend (forward-compat for the upcoming SliceModal Bundle tier):
  - api.getLibraryFileFilamentRequirements / getArchiveFilamentRequirements
    accept an optional 4th-arg bundle context object

maziggy 988c00554e feat(slicer): multi-color slicing + per-plate filament discovery
The slice modal previously rendered exactly one filament dropdown and
  silently truncated multi-color 3MFs to a single profile, producing wrong
  colours on every multi-filament print. End-to-end fix across sidecar,
  backend, and frontend.

  Sidecar (orca-slicer-api / bambuddy/profile-resolver, separate commit):
    - /slice accepts up to 16 repeated filamentProfile parts; slicing
      service materializes each and joins paths with `;` for
      --load-filaments.
    - /profiles/bundled emits filament_type and filament_colour per leaf
      so the bundled tier carries metadata into the modal.

  Bambuddy backend:
    - SliceRequest gains filament_presets: list[PresetRef]. Validator
      accepts three shapes (multi-color array, source-aware singular,
      legacy bare-int id) and lands them all on a populated array before
      the route handler runs — fully backwards-compatible.
    - SlicerApiService.slice_with_profiles takes filament_profile_jsons:
      list[str] and sends one filamentProfile multipart part per profile
      (in submission order) so the sidecar receives N profiles cleanly.
    - New service slice_preview runs the sidecar's slice_without_profiles
      against an unsliced project file's embedded settings, parses the
      result's slice_info.config, and returns the canonical per-plate
      filament list. Cached by (kind, source_id, plate_id, content_hash)
      with LRU eviction at 256 entries, per-key asyncio.Lock prevents
      thundering-herd; transient sidecar failures are NOT cached so they
      retry naturally; parse failures ARE cached (deterministic property
      of the input, no point re-running).
    - /filament-requirements endpoint chain: slice_info.config (existing,
      sliced files) → preview-slice (new, unsliced project files) →
      project_settings.config + painted-face heuristic with 5% noise
      threshold (sidecar-down fallback).
    - threemf_tools gains extract_project_filaments_from_3mf and
      extract_plate_extruder_set_from_3mf — the latter unions object
      top-level extruder, per-part overrides, and painted-face quadtree
      leaves (1-E nibbles in paint_color attrs of <triangle> elements
      inside per-object .model files).
    - Cloud preset listing no longer fetches per-preset detail (Bambu's
      rate limit at ~10/sec returns 429 on every request for users with
      50+ presets). Unified-listing dedup pass instead backfills metadata
      cross-tier so a cloud entry that wins dedup over a same-named local
      entry inherits the local's filament_type / filament_colour.

  Frontend:
    - SliceModal multi-step: plate-picker first when the source is a
      multi-plate 3MF, then preset dropdowns. One filament dropdown per
      AMS slot the plate actually uses, each pre-picked by metadata
      match against user's local + standard presets via existing
      colorsAreSimilar / normalizeColorForCompare utils.
    - SliceModal-only tier priority is now local → cloud → standard
      (was cloud → local → standard). Other consumers of /slicer/presets
      keep the existing cloud-first order.
    - Submits filament_presets array; backfills the legacy singular
      filament_preset from the array's first entry for stale-tab
      compatibility.
    - i18n keys added across all 8 locales: slice.filamentSlot,
      slice.tier.{local,cloud,standard}, slice.cloud.{notAuthenticated,
      expired,unreachable}, slice.noPresetsForSlot,
      slice.allPresetsRequired (en + de fully translated; six others
      seeded with English copies pending native translation, matching
      the project's existing flow).

  Permissions: no new endpoint paths added. Preview-slice runs inside
  /filament-requirements (LIBRARY_READ / ARCHIVES_READ) and multi-filament
  dispatch runs inside POST /slice (LIBRARY_UPLOAD). No auth surface
  widened.

  Tests: 6 SliceRequest schema tests for multi-filament + legacy-new
  precedence; 9 unit tests for slice_preview cache behaviour (LRU
  eviction with lock cleanup, content-hash invalidation, concurrent
  thundering-herd guard, no-cache-poison on transient sidecar failure);
  15 unit tests for the two new threemf_tools helpers (5 + 10 cases
  including the 60/40 painted-threshold regression pin); a multi-filament
  wire-format test pinning the multipart part count + order; 22 frontend
  SliceModal tests covering plate picker, multi-color render,
  metadata-aware pre-pick, manual override, and the new tier order.
