+## Sea Haven Governance
+
+**Standards authority**: The engineering handbook is the single authority for coding standards, naming conventions, and workflow configuration. Do not justify changes by citing it in PR bodies.
+
+**Work authority**: Jira is the source of truth for work status. Before creating a ticket, search Jira for duplicates. Route product work to DEV, infrastructure and platform work to PLAT, and security work to SEC.
+
+**Branch names**: Use `feature/`, `fix/`, `hotfix/`, `chore/`, `docs/`, `refactor/`, or `release/` with a kebab-case description. Do not include Jira keys in branch names. Dependabot branches and emergency reverts are exempt from this rule.
+
+**PR title format**: `type(scope): description (DEV-123)` — Jira key required on every non-exempt PR. Dependabot and permission-controlled emergency reverts are exempt.
+
+**PR body headings** (exact, in this order):
+1. Summary
+2. Validation
+3. Tests
+4. Notes
+
+**Prohibited**: AI-attribution footers in commits, PRs, comments, or generated artifacts.
+
+**Security gates**:
+- PRs touching payment flows, authentication logic, secret handling, AWS IAM, or untrusted user input require security review.
+- IAM role, policy, or resource-permission changes require cross-family review.
+
+**CI workflow refs**: All `uses:` workflow refs must be pinned to a full commit SHA with an inline version comment — `owner/repo/.github/workflows/file.yaml@<full-sha> # vX.Y.Z`. No floating tags or branch refs.
