# M10-12 Status
|
|
|
|
status: done
|
|
task: One NLA edit operator with Main transaction, undo/redo and save/reopen
|
|
updated: 2026-08-16 America/New_York
|
|
|
|
## Scope
|
|
|
|
The bounded `moveNLAStrip` command moves one existing Action Clip while preserving
|
|
its duration and time mapping. It requires the current `baseRevision`; stale commands
|
|
return `REVISION_CONFLICT` before Main mutation. The Worker derives a candidate stack
|
|
through the pure protocol helper, validates Action/path/range/overlap gates, and commits
|
|
it through one authoritative Main `setNLAStack` transaction. The native history entry
|
|
therefore covers the exact pre-edit `.blend` bytes.
|
|
|
|
This task intentionally opens only the move operator. Create/remove/resize/active,
|
|
multi-track blending, Transition/Meta/Sound, NLA UI and export remain blocked or planned.
|
|
|
|
## Evidence
|
|
|
|
- Pure contract: `web/protocol/nla.ts` and `web/tests/unit/nla.test.mjs`, 2/2 tests.
|
|
The source stack is not mutated; overlap, unknown identity and frame budget errors
|
|
are deterministic.
|
|
- `WEB_TEST_PORT=5528 npm --prefix web run test:nla-operator`: unit 2/2 and Chromium
|
|
1/1 passed. The browser path proves stale revision rejection, Main move 20..40 ->
|
|
5..25, monotonic revision/delta, undo to 20..40, redo to 5..25, save/reopen at
|
|
5..25, and native frame-10 evaluation at X=2.5.
|
|
- `npm --prefix web run typecheck`, `npm --prefix web run lint`, and `git diff --check`:
|
|
passed.
|
|
|
|
## Rollback
|
|
|
|
Remove `moveNLAStrip` from `web/protocol/nla.ts` and `web/protocol/web-engine.ts`,
|
|
remove the Worker conversion, unit/E2E tests and package command, and delete this
|
|
status file. Restore the M10 count to 11/15. Keep M10-11 read-only evaluation and
|
|
the pre-existing whole-stack `setNLAStack` authoring path.
