 2. **Design & Verify Contracts (Semantic Protocol)**:
    - **Drafting**: Define [DEF] Headers and Contracts for all new modules based on `semantic_protocol.md`.
+   - **TIER Classification**: Explicitly assign `@TIER: [CRITICAL|STANDARD|TRIVIAL]` to each module.
+   - **CRITICAL Requirements**: For all CRITICAL modules, define full `@PRE`, `@POST`, and (if UI) `@UX_STATE` contracts.
    - **Self-Review**:
      - *Completeness*: Do `@PRE`/`@POST` cover edge cases identified in Research?
      - *Connectivity*: Do `@RELATION` tags form a coherent graph?
