# Plan 02-03 Summary: Human Verification — Browse Experience

## What Was Verified

User confirmed all four NAV requirements work correctly in the live running TUI after two bugs were found and fixed during the checkpoint session.

## Bugs Found and Fixed

### Bug 1: j/k navigation crash
- **Error:** `action_scroll_cursor_down/up()` does not exist on Textual's DataTable
- **Fix:** Changed to `action_cursor_down()` / `action_cursor_up()` (correct Textual API)
- **Commit:** `fix(02-browse): use correct DataTable cursor action methods (j/k navigation)`

### Bug 2: Live filter silently did nothing on rooms/containers views
- **Root cause 1:** `_apply_filter` had `if self._view_mode != "items": return` guard
- **Root cause 2:** Rooms and containers data was not cached — only written directly to DataTable in `_load_view`, leaving nothing for filter to iterate over
- **Fix:** Added `self._rooms` and `self._containers` caches populated in `_load_view`; extended `_apply_filter` to handle all three view modes
- **Commit:** `fix(02-browse): extend live filter to rooms and containers views, cache row data`

## Verified Requirements

| Requirement | Description | Status |
|-------------|-------------|--------|
| NAV-01 | j/k cursor movement, gg/G top/bottom jump | ✓ Verified |
| NAV-02 | / opens live filter, Escape clears | ✓ Verified |
| NAV-03 | Enter drills rooms→containers→items, q goes back | ✓ Verified |
| NAV-04 | Breadcrumb updates at every level transition | ✓ Verified |

## Key Files

- `possession/tui/screens/main.py` — MainScreen with all navigation, filter, drill-down, breadcrumb
- `possession/tui/widgets/breadcrumb.py` — Breadcrumb widget
- `possession/tui/app.py` — PossessionApp shell

## Outcome

Phase 2 browse experience approved by user. All 4 NAV requirements verified in the live terminal app.
