1. Runtime Platform Context

• 1.1 Add behavior tests for Windows and macOS interactive-assistant instructions.
• 1.2 Detect the host operating system once at startup and register immutable runtime context.
• 1.3 Append platform-specific command, path, service, and desktop concepts to interactive-assistant instructions.
• 1.4 Preserve a platform-neutral fallback for unsupported hosts.

2. Documentation and Validation

• 2.1 Document platform-aware interactive-assistant guidance and its feature-support boundary.
• 2.2 Run focused behavior tests, the full test suite, strict OpenSpec validation, and the required refactoring review; record the known unrelated macOS failures and Windows-host build limitation in implementation evidence.
