# M10-14 Status
|
|
|
|
status: done
|
|
task: Validate source hash, frame range, byte budget and version for every Physics cache family
|
|
updated: 2026-08-16 America/New_York
|
|
|
|
## Scope
|
|
|
|
Every Physics family cache now uses cache schema 1 and binds its family, desktop or
|
|
server bake origin, Blender 5.2 version, source blend/settings/input/cache SHA-256,
|
|
frame range, total byte length and per-frame byte offset/length/SHA-256. `COMPLETE`
|
|
caches require every frame; `PARTIAL` caches may omit frames but remain strictly
|
|
ordered and byte-contiguous. Per-frame and total cache budgets match the existing
|
|
bounded Simulation cache policy.
|
|
|
|
`verifyPhysicsCachePayload` hashes the actual current blend, full cache payload and
|
|
every frame before consumption. Family/source/version/range/budget drift fails closed.
|
|
This task validates cache identity and bytes; it does not implement a Blender family
|
|
decoder or change the existing cache playback capability block.
|
|
|
|
## Evidence
|
|
|
|
- `node --test web/tests/unit/physics-cache-family.test.mjs`: 3/3. All seven families
|
|
and both desktop/server sources pass; source/payload drift and family/schema/version/
|
|
range/budget/undeclared-field failures return stable codes.
|
|
- `WEB_TEST_PORT=5533 npm --prefix web run test:physics-cache-family`: unit 3/3 and
|
|
Chromium Worker 1/1, matching the M10-14 golden.
|
|
- M10-13 probe Chromium 1/1, Physics Main reader, M10-05 Simulation cache identity
|
|
unit 5/5 + Chromium 1/1, typecheck, lint, production build (74 modules), and
|
|
`git diff --check`: passed.
|
|

|
## Rollback
|
|
|
|
Restore the former Physics cache binding, remove the two new cache hash error codes,
|
|
unit/Worker/E2E/golden/package command and this status file, then restore M10 to
|
|
13/15. Keep M10-13 solver probing and the existing GN Simulation cache schema 2.
