+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Follow-up to TASK-33: `[main:mpv] MPV IPC connect requested.` still emits at INFO repeatedly during startup retries. Gate this request-attempt log behind debug level so normal runs stay quiet.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Non-debug runs do not emit repeated 'MPV IPC connect requested.' lines during retry loops.
+- [x] #2 Debug runs still emit connect-request attempt logs for diagnosis.
+- [x] #3 Connection behavior and retry timing are unchanged.
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Moved MPV connect-request log in `src/core/services/mpv.ts` from INFO to DEBUG so retry loops are silent at default log level while preserving diagnostics in debug mode. Added regression tests in `src/core/services/mpv.test.ts` asserting zero connect-request logs at info level and one connect-request log at debug level. Validation: `bun run build && node dist/core/services/mpv.test.js` (pass).
+<!-- SECTION:FINAL_SUMMARY:END -->
+
+## Definition of Done
+<!-- DOD:BEGIN -->
+- [x] #1 Add/adjust unit tests covering debug vs non-debug logging for connect requests.
+- [x] #2 Run targeted mpv service tests and build/typecheck path used for this change.
+<!-- DOD:END -->
