## 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:

```json
{
  "host": "macOS",
  "meetingMetadataProvider": "MacOsMeetingMetadataProvider",
  "calendarMeetingProvider": "MacOsCalendarMeetingProvider",
  "meetingStartPromptProvider": "MacOsMeetingStartPromptService",
  "screenshotProvider": "MacOsDesktopIntegrationClient",
  "workflowEditorProvider": "MacOsWorkflowRulesEditorWindowService",
  "workflowEditorAvailable": true,
  "calendarRecordingPromptsEnabled": true,
  "speakerIdentificationEnabled": true,
  "screenshotOcrEnabled": true,
  "funAsrBackendEnabled": true,
  "funAsrDiarizationEnabled": true,
  "whisperLocalDiarizationEnabled": true
}
```

The installed arm64 Mach-O helper returned:

```json
{"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`.
