+## Project layout

+## Local CLI smoke test
+
+```bash
+npm run build
+node dist/cli.js -h
+npm link   # optional: install `srcpush` globally
+```
+
+## Hash utility sync
+
+`src/lib/hash.ts` must stay in sync with `api/src/utils/hash-utils.ts` in the monorepo. Any hashing change requires updating both files.
