 ## Implementation Notes
 
-## Upgrade Commands
-
-From Astral's Python 3.14 announcement:
-```bash
-# Install Python 3.14t
-uv python install 3.14t
-
-# Upgrade project to use 3.14t
-uv python upgrade 3.14t

+## Python 3.12 Upgrade Complete (2025-10-25)
+
+### Summary
+Successfully upgraded from Python 3.11.11 to 3.12.9. All 516 tests pass with 58% coverage maintained.
+
+### Changes Made
+- Updated `.tool-versions` to python 3.12.9
+- Updated `pyproject.toml` to require python >=3.12,<3.13
+- Pinned `ziggy-pydust==0.25.1` for Zig 0.14.0 compatibility (0.26.0 requires Zig 0.15.1)
+- Rebuilt Zig extension modules successfully
+
+### Regressions Fixed During Manual Testing
+1. **Play/pause icon not updating**: Added explicit `update_play_button()` calls in `player_core.py`
+2. **Queue not populating from media key**: Added queue population logic from library view
+3. **Search not filtering**: Fixed `perform_search()` to directly populate queue view
+4. **App startup failure**: Fixed initialization order for `queue_handler` reference
+
+All fixes in: `core/controls/player_core.py`, `core/player/handlers.py`, `core/player/__init__.py`
+
+### Testing Gap Analysis
+Created follow-up tasks to address test coverage gaps discovered during migration:
+- **task-074**: Add integration tests for recent bug fixes (high priority)
+- **task-075**: Add unit tests for PlayerEventHandlers class (0% coverage)
+- **task-076**: Increase PlayerCore coverage from 29% to 50%+
+
+### Python 3.12 Compatibility Notes
+- No deprecation warnings triggered
+- Asyncio behavior stable (limited usage in project)
+- VLC bindings working correctly
+- All dependencies compatible
+
+### Next Steps for task-059
+- Proceed to AC #2: Upgrade to Python 3.13
+- Monitor for Python 3.13 specific changes (PEP 701 f-strings, etc.)
+- Continue validating Zig/ziggy-pydust compatibility at each step

+Add automated tests for code paths added during Python 3.12 migration bug fixes. These areas currently lack test coverage and caused regressions during manual testing.

+- [ ] #2 Add E2E test: Search filtering correctly populates queue view without reloading library
+- [ ] #3 Add unit test: update_play_button() changes icon for play/pause states
