# AI Worklog

This file records important AI-assisted development actions.

Each entry should include:

- result
- open issues (if any)

Entries must be concise and chronological.

## 2026-03-15 - build

- objective: Replace the temporary history debug overlay with a dedicated history mode in the terminal UI.
- files modified: `src/app/ui.py`, `tests/test_ui.py`
- key decisions: Keep `b` and `f` unchanged, add separate history-mode selection state inside the UI, hide the tree while history mode is active, and use Enter to select a history entry and return to the tree view.
- validation: `make fix`, `make quality`
- result: History mode now shows only the history list, supports Up/Down selection, allows Enter to jump to a prior directory, and exits cleanly back to normal navigation.
- open issues: None.
