## ADDED Requirements

### Requirement: Meeting Assistant defines macOS and Linux build targets
Meeting Assistant SHALL define macOS and Linux build targets separately from the Windows build target.

Windows-only integrations such as WASAPI capture, global hotkeys through user32, and Outlook Classic COM SHALL NOT be compiled into macOS or Linux targets.

#### Scenario: Non-Windows target compiles
- **WHEN** Meeting Assistant is built for macOS or Linux
- **THEN** Windows-only source files and package dependencies are excluded
- **AND** the application compiles with portable service registrations or explicit unsupported implementations

#### Scenario: Windows target keeps Windows integrations
- **WHEN** Meeting Assistant is built for Windows
- **THEN** WASAPI audio capture, Windows global hotkeys, and Outlook Classic COM enrichment remain available

#### Scenario: Platform-specific tests are gated
- **WHEN** tests run for a platform target
- **THEN** tests for incompatible platform APIs are excluded or compiled only for their matching target
