PRs must flow smoothly through review to reach production. Large PRs should be split into smaller, manageable ones.

## Submitting PRs

1. **Title and Summary**:
   - Use a scannable title: `[Subsystem] Action Description #Issue` (e.g., `[IAM] Add role-based access control #567`).
   - Include context in the summary: what changed, why, and any issue references.
