Verification evidence

Verified on macOS 26 on 2026-07-25.

Automated checks

• Focused macOS/calendar/screenshot/OCR tests: 35 passed, 0 failed.
• Full portable test project: 441 passed, 6 failed, 447 total. The six failures are existing macOS-incompatible tests for Windows path assumptions, GDI+ taskbar rendering, and user-environment fallback; none cover this change.
• Portable net10.0 build: succeeded.
• Windows net10.0-windows10.0.19041.0 target build with Windows targeting enabled: succeeded with 0 warnings and 0 errors.
• openspec validate add-macos-meeting-integrations --strict: valid.
• Sequential DRY, SOLID, and KISS reviews were completed and their findings implemented.
• Final independent standards and spec reviews reported no findings.

Live macOS installation

The recording status was idle before deployment. The repository updater published the portable build, installed it into ~/Library/Application Support/MeetingAssistant/app, restarted the LaunchAgent, and passed its health check.

GET /diagnostics/platform-capabilities returned:

{
  "host": "macOS",
  "meetingMetadataProvider": "MacOsMeetingMetadataProvider",
  "calendarMeetingProvider": "MacOsCalendarMeetingProvider",
  "meetingStartPromptProvider": "MacOsMeetingStartPromptService",

The installed arm64 Mach-O helper returned:

{"features":["calendar","prompt","screenshot","crop"],"status":"ok"}

Direct native screenshot capture selected the foreground ChatGPT window and produced a valid 3258 by 1920 PNG. The asymmetric native crop regression test also proves OCR top-left pixel coordinates are preserved.

The live calendar diagnostic returned provider=MacOsMeetingMetadataProvider, timedOut=false, and a normal no-matching-event result. EventKit reported missing Full Calendar Access with stable exit code 77, after which the Calendar automation fallback completed; the scheduler logged Synced 0 Teams calendar meetings.
