Schema changes only: adding/removing/modifying columns, tables, indexes, or feature flags.

commons-packages/backend/schema.sql. It is a generated artifact. Express every schema change as a migration only. Ifschema.sqlshows up ingit status, revert it (git checkout -- commons-packages/backend/schema.sql).
Patient data operations (backfilling, updating, transforming data) → Use commons-packages/backend/jobs/ instead.

This generates a timestamped scaffold file only — it does not require a database connection. Always use it; never hand-write a migration file or invent its timestamp.

Use when implementing batched lookups, adding a new loader, wiring field resolvers to loaders, or avoiding N+1 via request-scoped batching and caching.
Use the GitHub CLI (gh) for PRs, repos, search, releases, and API access from the terminal. Use when attempting to get information about other repos or about PRs in this repo.
Use Graphite CLI (gt) for stacked PRs and branch management. Use when creating branches, committing changes, submitting PRs, syncing with trunk, or managing stacked pull requests.
