NFR: Compatibility

Operate across supported macOS versions and CPU architectures.

Requirement

• Support macOS 13+ on Apple Silicon and Intel Macs.
• Intel Macs may experience doubled latency but must remain functional.

Rationale

Wider OS support increases addressable market while retaining acceptable performance.

Acceptance Criteria

• Manual QA passes on Intel MBP 2020 (macOS 13).
• Automated smoke test on GitHub Actions Intel runner passes.
• Latency SLA documented separately for Intel.

Test-Driven Design

Add failing cross-arch smoke tests to CI runners before porting; success criteria met when tests pass on Intel and Apple Silicon.
