• Checkout used: loader/recording-plus-button-actions-direct-film-v2
• Reload tag used: pfilm4
• App launched at: /Users/runner/Library/Developer/Xcode/DerivedData/cmux-pfilm4/Build/Products/Debug/cmux DEV pfilm4.app
• Config wrote to $HOME/.config/cmux/cmux.json exactly as requested (with demo-shell, demo-workspace, and newWorkspace context menu setup).
• Recording log doc created: docs/recordings/plus-button-actions-direct-film-v2.md

Verification performed:

• Direct captures executed with screencapture and videos.tsv appended only when .mov was non-empty.
• videos.tsv entries:
  • preflight started 2026-04-30T10:26:48Z, stopped 2026-04-30T10:26:57Z, status ok.
  • repro started 2026-04-30T10:27:03Z, stopped 2026-04-30T10:28:03Z, status ok.
• Required milestones verified from extracted/reviewed repro frames + OCR:
  • Context menu from titlebar plus appeared with New Terminal, Demo Shell, Demo Workspace ordering.
  • right click menu action works output was captured (OCR-confirmed).
  • Final New tab browser surface remained visible through end of capture (with browser omnibar/globe-tab UI present).
• No product code changes made (recording task only).
• Frame extraction was done via temporary Swift/AVFoundation script because ffmpeg is not installed on runner.

Recorded video names:

• .runner/videos/preflight.mov
• .runner/videos/repro.mov
