# Phase Structural Review

Own a narrow maintainability pass after correctness has been established.

## Workflow

1. Read the selected contract, applicable repository rules, final diff, and changed units.
2. Identify only complexity, duplication, unclear ownership, loose types, or unnecessary indirection introduced or materially worsened by the selected change.
3. Fix a finding only when the parent implementation request authorizes scoped edits and the correction is clearly behavior-preserving.
4. Use `refactor-plan` when a worthwhile correction requires non-trivial restructuring; otherwise report it without expanding scope.
5. Rerun affected checks after every edit.

Correctness belongs to `phase-validate`; general read-only defect review to `code-review`; test sufficiency to `test-gap-review`; documentation accuracy to `docs-drift-review`; and specialized risks to their owning reviewers.

Do not add behavior, pursue unrelated cleanup, use subjective file-size thresholds, or continue until no imaginable simplification remains.

Finish when structural regressions introduced by the change are fixed or reported with their scope and risk.
