# Execution State: Enable Mouse Click Support

## Progress
- [x] Phase 1: Foundation — `__init__` cleanup and `GitPanel` public API
- [x] Phase 2: Verification — empirically test TabActivated behavior
- [x] Phase 3: Implementation — enable mouse and add handler
- [x] Phase 4: Manual verification

## Key Decisions
- Phase 1: `_mounted` flag set to `True` at very end of `on_mount` (after timer scheduled)
- Phase 2: TabActivated DOES fire for programmatic `tabbed.active` assignment — clean refactor is safe
- Phase 2: 3 mouse focus tests in RED state (expected), 6 other mouse tests pass already
- Phase 3: Deviated from plan — kept direct `_focus_active_tab()` calls in keyboard actions due to Textual's TabPane._on_descendant_focus oscillation. Used click-detection gate (`_tab_click_pending`) instead. All 446 tests GREEN.

## Learnings
- Phase 1: `focus_default()` added to GitPanel as public API for focus delegation
- Phase 1: All instance attrs now in `__init__` — `_auto_select_done`, `_auto_select_attempts`, `_mounted`

## Code Context
- Modified: `src/perch/widgets/git_status.py` (added `focus_default()`)
- Modified: `src/perch/app.py` (moved attrs to `__init__`, added `_mounted`, replaced `panel._file_list.focus()`)
- Modified: `tests/test_git_status.py` (added `TestFocusDefault`)
- Modified: `tests/test_app.py` (added TestTabActivatedEvent, TestMouseClickTabFocus, TestMouseKeyboardInteraction)
- Modified: `src/perch/cli.py` (removed `mouse=False`)
- Modified: `src/perch/app.py` (added `on_tabbed_content_tab_activated`, `on_click` handler, `_tab_click_pending` flag)
