## Current Work (newest first)

- [2026-02-22T00:02:53Z] intent: add invariants coverage for AniList runtime state/media state tests and document runtime ownership/mutation/reducer boundaries under composition guidance.
- [2026-02-22T00:02:53Z] plan: update `src/main/runtime/anilist-state.test.ts`, `src/main/runtime/anilist-media-state.test.ts`, and `docs/architecture.md`; run focused bun tests for both runtime test files.
- [2026-02-22T00:04:21Z] complete: added TASK-79 slice B invariant tests for queue metadata preservation/token-clear non-mutation/media-reset behavior and documented migrated runtime-state reducer ownership rules; verified with `bun test src/main/runtime/anilist-state.test.ts src/main/runtime/anilist-media-state.test.ts` (8 pass, 0 fail).

## Files Touched

- `docs/subagents/agents/opencode-task79-sliceb-20260222T000253Z-m2r7.md`
- `docs/subagents/INDEX.md`
- `docs/subagents/collaboration.md`
- `src/main/runtime/anilist-state.test.ts`
- `src/main/runtime/anilist-media-state.test.ts`
- `docs/architecture.md`

## Assumptions

- TASK-79 is the owning backlog ticket for this slice.
- Requested scope is test/docs only; no production behavior changes required.

## Open Questions / Blockers

- None.

## Next Step

- Handoff complete.
