Why

The portable macOS application can capture meeting audio and expose menu-bar controls, but it still registers unavailable/no-op implementations for calendar metadata, recording prompts, and active-window screenshots. The local macOS environment also disables screenshot OCR, speaker identification, the managed FunASR backend, FunASR diarization, and Whisper-local diarization even though their managed implementations are portable.

What Changes

• Read Teams meeting metadata and prompt candidates from calendars available through macOS EventKit, including Outlook-synced calendars.
• Show a native macOS record/skip prompt for due calendar meetings.
• Capture the foreground macOS application window through a bundled native helper so screenshot OCR can use the existing portable OCR pipeline.
• Register the real macOS integrations instead of no-op/unavailable providers.
• Enable the portable OCR, speaker identification, FunASR, and diarization configuration in the macOS runtime environment.
• Expose a diagnostic capability surface that proves the effective platform providers and enabled feature switches.
• Preserve all Windows-specific COM, notification, screenshot, tray, hotkey, and audio registrations.

Capabilities
