M12-07G Status

status: done task: PLY ASCII and binary little-endian capability declarations updated: 2026-08-18 America/New_York enablingTask: true parityStateChange: false

Scope

Pinned Blender 5.2 WM_OT_ply_export now has two independently declared capability variants for the same selected two-triangle mesh: PLY_ASCII and PLY_BINARY_LITTLE_ENDIAN. The report binds the export settings, source/operator anchor, runtime identity, header semantics, and byte hashes; the variant is never inferred from a shared .ply extension. This enabling task freezes desktop capability only and does not expose a Web PLY parser or import route.

Evidence

build_blender_5.2.0/bin/blender -b --factory-startup --python tools/web/generate-ply-capability-fixtures.py -- tests/files/web/m12_ply_capability_v1 tests/golden/M12-07G/capability-report.json generated an ASCII PLY with four vertices/two faces and a binary little-endian PLY with the same four vertices/two faces. Both headers explicitly carry their independent encoding declarations and Blender export settings are recorded in the report.
node tools/web/check-ply-capability-fixtures.mjs matched every runtime identity field to the pinned M12-05A inventory, validated the ascii and binary_little_endian variants, checked the vertex/face element counts and artifact hashes, regenerated both files in a fresh temporary directory, and passed byte-for-byte determinism: ply-capability-fixtures-ok ascii=ascii binary=binary_little_endian vertices=4 faces=2 deterministic=true next=M12-07H.
python3 -m py_compile tools/web/generate-ply-capability-fixtures.py and node --check tools/web/check-ply-capability-fixtures.mjs passed. The package hash remains frozen and N-023 parity remains blocked; no PLY Web UI route was exposed.

Rollback

Remove the PLY capability generator, checker, fixtures, report, manifest, and this status entry. Restore M12-07F as the queue tail and move the machine queue back to M12-07G. No parity ledger rollback is required.
