+- status: `done`
+- branch: `main`

+## Current Work (newest first)
+- [2026-02-21T04:41:15Z] handoff: switched connect-request logging from INFO to DEBUG in `src/core/services/mpv.ts`; added regression tests for info/debug behavior in `src/core/services/mpv.test.ts`; build + mpv suite passing; linked and completed `TASK-95`.
+- [2026-02-21T04:40:32Z] test: `bun run build && node dist/core/services/mpv.test.js` (pass, 15/15).
+- [2026-02-21T04:39:42Z] test: red confirmed before implementation (2 failing assertions for info/debug log-level expectations).
+- [2026-02-21T04:38:20Z] progress: created backlog ticket `TASK-95` for this logger-path follow-up to `TASK-33`.
+- [2026-02-21T04:37:48Z] intent: TDD-first fix for `[main:mpv] MPV IPC connect requested.` log spam; keep functional behavior unchanged.
+- [2026-02-21T04:37:48Z] progress: read `docs/subagents/INDEX.md`, `docs/subagents/collaboration.md`; identified emitter in `src/core/services/mpv.ts`.
+- [2026-02-21T04:37:48Z] progress: backlog check found prior related completed task `TASK-33`; scoping follow-up for current logger path.

+## Files Touched

+- `src/core/services/mpv.ts`
+- `src/core/services/mpv.test.ts`
+
+## Assumptions
+- Noise source is `logger.info('MPV IPC connect requested.')` in `src/core/services/mpv.ts`.
+- Desired behavior: suppress this line at non-debug log levels.
+
+## Open Questions / Blockers
+- none
+
+## Next Step
+- Await user verification in runtime logs; no further code changes planned.
