Supersedes #1212 with the same content as one commit on top of main: #1212 carries two conflict-resolution merges, so GitHub cannot rebase it, and rebase is the only merge method this repository allows. Its CI was green and CodeRabbit's one finding is addressed.

Results row for the computer-use e2e pass on macOS, run against the CI artifact of main @ 0bed36852 (build run 38581408372, notarized DMG, About 2.0.0 (dmg)), on macOS 26.5, Mac mini M1, one 4K display at 2x.

Scope: MCP server section on both servers (stdio and in-app HTTP, SDK client), #1194 on macOS, the #1180 editor tools, MP4/GIF export over MCP (#1197), Openscreen captions, and a scoped app slice. Every take used the legacy selector or MCP; Apple's picker slice was skipped at the operator's request.

Defects found:

1. P1: in-app startRecording returns "capture had not started" after 120 s while the bar records, and on macOS the take is then lost (no file, no editor). Same root cause as on Windows, fixed on main by c541fff after this build; needs a macOS re-run.
2. P2: while an Openscreen mcp stdio session runs, opening OpenScreen from Finder or open starts no GUI; LaunchServices activates the mcp process, which turns Foreground with its own Dock icon after its first take. open -n works around it.
3. P3: getFrames cannot read a GIF ("Chromium could not decode the video (media error 4)"), with path or after a GIF export, on both servers.
4. P3: an MCP window take with system audio is silent when the sound comes from another app (SCContentFilter(desktopIndependentWindow:) keeps only that app's audio); display takes are fine.

Checklist text: step 4 now names universalAccessAuthWarn as the owner of the macOS permission prompts, and the CI-artifact section records that a launch from Terminal files them under Terminal, with the open --env launch that avoids it.
