M16-GAP-00022 Status

status: done task: Sound data-block LOCAL_EXACT slice updated: 2026-08-20 America/New_York

scope: Blender 5.2 bSound identity and bounded sound resource fields through the same generated fixture in desktop and WASM/Main: source path, packing state, volume, pitch, channel count and sample rate.

evidence:

• tools/web/generated/M16-GAP-00022.py deterministically creates sound:WebGapSound from the repository WAV fixture and saves the Blend fixture.
• Desktop reopen report matches exactly: sound:WebGapSound, //WebGapSound.wav, unpacked, volume/pitch 0.0, one audio channel and 8000 Hz.
• The reader matches Blender's DNA bSound type and emits the same sounds resource in Scene IR; protocol validation bounds the resource fields.
• WASM/Main opened the same fixture, matched every desktop sound field, saved and reopened with an identical snapshot, and rejected a truncated Blend without mutating the loaded Main.
• build_blender_5.2.0/bin/blender -b --factory-startup --python tools/web/generated/M16-GAP-00022.py -- tests/files/web/generated/M16-GAP-00022-datablock-Sound.blend exited 0.
• npm --prefix web run test:generated-gap -- --task M16-GAP-00022 exited 0.
• node tools/web/check-generated-gap.mjs --task M16-GAP-00022 exited 0.

artifacts: tests/golden/M16-GAP-00022/manifest.json contains SHA-256 for the parent manifest, fixture, generator, desktop/Web checkers, reader/protocol/runtime and both reports.

knownRisk: This closes only the datablock:Sound resource-observability slice. Audio playback, sequencer editing and other data-blocks remain separate tasks.

rollback: remove this task's fixture, generator, desktop checker, checker branch, reader/protocol/runtime changes, reports, manifest, status and context; restore M16-GAP-00021 as the queue tail without editing its successful evidence.
