Panel Guide

Timeline Inspector

The panel uses a Redux-style inspector layout:

• Left side: timeline rows (@@INIT, SNAPSHOT/<step>, COMMAND/<type>, ERROR/<type|requestId>).
• Right side: tabs for Action, State, and Diff.
• Selection is local/read-only and does not mutate inspected runtime state.

Timeline Controls

• Follow latest: keeps selection pinned to newest row.
• Display limit: limits rows rendered in the panel.
• Prune to limit: truncates retained rows for the active machine.
