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.
