Additional Notes

---

Note

Adds in-run search and richer run selection details to the Textual TUI.

• New case-insensitive regex search (press s) in ViewRunScreen; displays results in a modal, highlights matches in prompt/completion, auto-scrolls to the selected line, and clears highlight after a short delay
• Added run details side panel in SelectRunScreen showing metadata like avg reward, metrics, runtime, env_args, and sampling_args; updates as runs are highlighted
• Introduces helpers for match styling and wrapped-line offset calculation to enable precise scrolling; updates key bindings and layout/CSS for search and details panels

Arrow keys interfere with search Input cursor navigation

Medium Severity

The on_key handler in SearchScreen unconditionally intercepts all arrow key events at the screen level without checking which widget has focus. Since the Input widget is focused on mount (line 1068), pressing left/right arrow keys to navigate within the search query text also triggers _switch_column(), causing the active result column to change unexpectedly. This makes it difficult for users to edit their search pattern using arrow keys because the UI responds to those keys in ways the user doesn't intend. The handler needs to check if the Input has focus before intercepting arrow keys for column/selection navigation.

🔬 Verification Test

Why verification test was not possible: This is a TUI (Textual Terminal User Interface) application that requires an interactive terminal environment to test. The bug involves keyboard event handling during user interaction, which cannot be easily unit tested without mocking the entire Textual event system and terminal environment. The bug is evident from code inspection: on_key unconditionally intercepts arrow keys at the screen level while the Input widget is focused by default on mount, causing unintended side effects when users try to navigate within their search text.

This is intended behavior. This is mostly mean for quick searches, so if there's a mistake, hit the back-key and type again. This override allows for quick and intuitive result selection with the arrow keys.
