Summary

  • Extend tmux list-panes format to emit pane, window, and session activity timestamps while preserving the first three fields.
  • Derive idleSeconds from the first populated finite positive source, ordered pane_activity -> window_activity -> session_activity.
  • Clamp future activity epochs to 0 and keep idleSeconds null only when all sources are absent.

Why

On tmux 3.4, #{pane_activity} is empty in the mosaic-fleet socket while #{window_activity} is populated. Feeding window_activity restores the existing classifyReadiness idle/stuck path without changing classifier thresholds or rendering.

Tests

  • npx turbo build --filter=@mosaicstack/mosaic^...
  • pnpm typecheck
  • pnpm lint
  • pnpm format:check
  • pnpm --filter @mosaicstack/mosaic exec vitest run src/commands/fleet.spec.ts (176 tests)
