| Area | What to review |
|---|---|
| Routing | RESTful routes, shallow nesting, route helpers |
| Controllers | Thin, 1-line actions, strong params, callbacks audit |
| Models | Validations, scopes, callbacks, N+1 queries |
| Queries | Eager loading, pluck vs map, exists? vs present? |
| Migrations | Reversible, index names, null constraints |
| Security | Strong params, auth checks, output encoding |
| Testing | Correct spec type, minimal factories, no internal mocks |
| Jobs | Idempotency, retry config, log context |
| Level | Action |
|---|---|
| Critical | Blocks merge — fix before merging |
| Suggestion | Fix in this PR or separate ticket |
| Nice to have | Optional, does not block |
Goal: Deep security dive.
Goal: Structural review of boundaries and abstractions.
Goal: Respond to received feedback.
Anti-pattern: "LGTM! Will address in follow-up" — no performative agreement
