# Review Code (internal) Composed by `review-change` / `product-audit` within their conversation — on any agent, follow this file inline as the routed step. **Findings only; never edits, never refactors.** ## Scope The diff or path/glob the caller passes; default the current change vs the default branch. State the scope at the top of the returned table. ## Checklist (evaluate EVERY item — none is optional; n/a must be stated) ✓ No logic errors on the changed paths (trace each modified function's inputs → outputs, including boundary values) ✓ Every error path is handled — no swallowed exceptions, no empty catch, no silently-ignored return codes ✓ No duplicated logic (a changed block does not re-implement an existing helper — cite the existing one if it does) ✓ No dead code introduced (unused functions, params, imports, unreachable branches) ✓ No leftover TODO/FIXME/HACK markers in the diff ✓ Naming and file conventions match the project's docs (read them first; cite the convention violated) ✓ No new abstraction beyond what the SPEC requires (an interface/base class with one implementation is a finding) ✓ No new dependency not justified in the SPEC ✓ Simplification: any changed block that can lose lines without losing behavior (cite before/after) ✓ Edge cases the SPEC's dev scenarios name are actually handled in code, not just in tests ## Return exactly ``` REVIEW CODE — scope: <scope> | # | Finding | Sev | Evidence | Suggested fix | |---|---------|-----...
