Sea Haven review baseline (applies to every repo unless a repo-specific guideline overrides it):

- Severity: map findings to critical / high / medium / low. Reserve critical and high for correctness bugs, security issues, data loss, or broken contracts — not style.
- Secrets & config: flag any hardcoded secret, credential, or real `.env`/config value committed to source, and any sensitive value placed outside the platform's secrets manager.
- Security surface (raise as high): changes to authentication/authorization or access checks; IAM/policy/permission or infrastructure-access changes; changes to the exported signature or contract of a public handler/endpoint; and untrusted-input handling (request parsing, deserialization, file uploads, SSRF-prone fetches, and template/SQL/command construction — flag unescaped interpolation of dynamic or user-controlled data).
- Tests: flag new behavior that ships without a corresponding test, and "fixes" that only silence a check (added excludes, `noqa` / `# type: ignore`, skipped or `xfail`ed tests).
- Naming & conventions: flag resources or code that break the repo's established naming and layout conventions.
- Deferred work: a finding the author chooses to defer must be captured in a tracked issue, not dropped silently.

Only file a finding that anchors to a changed line and names a concrete failure mode. Do not police pre-existing issues outside the diff or raise pure style nits."""
