Review the type list in `src/planning/spec-v0.3.md` and compare with `src/types`. 2. Check for missing types, duplicate union members, or mismatched optionals. 3. Verify supporting types like `RawColor` and `OutputOptions` align with spec notes. 4. Flag acceptance criteria issues: build failure risk or circular imports. ## Common checks - Duplicated union members (e.g., `ColorState`). - Optional fields that spec marks required (or vice versa). - Extra types are acceptable if non-breaking; call them out as deltas. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/claushaas) — claim your Tome and manage your conversions.
