# M12-07D Status
|
|
|
|
status: done
|
|
task: split STL binary and ASCII capability declarations
|
|
updated: 2026-08-18 America/New_York
|
|
enablingTask: true
|
|
parityStateChange: false
|
|
|
|
## Scope
|
|
|
|
Pinned Blender 5.2 `WM_OT_stl_export` now generates binary and ASCII STL from the same selected
|
|
two-triangle mesh using identical axis, scale, unit, evaluation, and modifier settings. The report
|
|
keeps `STL_BINARY/ascii_format=false` and `STL_ASCII/ascii_format=true` as separate variants; it does
|
|
not infer the format from the `.stl` extension or claim Web parsing/import support.
|
|
|
|
## Evidence
|
|
|
|
- `build_blender_5.2.0/bin/blender -b --factory-startup --python
|
|
tools/web/generate-stl-capability-fixtures.py -- tests/files/web/m12_stl_capability_v1
|
|
tests/golden/M12-07D/capability-report.json` generated a 184-byte binary STL with two 50-byte
|
|
triangle records and a 213-byte ASCII STL with two facets/six vertex lines.
|
|
- `node tools/web/check-stl-capability-fixtures.mjs` matched runtime identity to M12-05A, validated
|
|
both independent encodings, regenerated the report/files byte-for-byte in a fresh directory, and
|
|
returned `stl-capability-fixtures-ok binaryTriangles=2 asciiFacets=2 deterministic=true next=M12-07E`.
|
|
- Package hash remains frozen. This enabling task does not change N-023 parity or expose an STL UI
|
|
route.

|
|
## Next Task
|
|
|
|
`M12-07E`: STL normal, unit, degenerate-triangle, and trailing-byte parity.
|
|
|
|
## Rollback
|
|
|
|
Remove the STL capability generator, checker, fixtures, report, manifest, and this status entry.
|
|
Restore M12-07C as the queue tail and move the machine queue back to M12-07D. No parity ledger rollback
|
|
is required.
