 The importer is checksum-idempotent: importing the same archive again is a safe no-op. It is not a file watcher or scheduled ETL process. The worker does not replace the API; both processes should run at the same time.

+When calendar-dependent growth features are enabled, bootstrap an independently reviewed external catalog after the importer and before `cmd/admin`/application startup:
+
+```bash
+go run ./cmd/calendar -action bootstrap -file /path/to/reviewed-calendar.json -current-jalali-year 1405 -reviewer reviewer-id -actor operator-id
+```
+
+The command rejects bundled review candidates, resumes the same reviewed version safely, and refuses to replace a different active version. Catalog rotation continues to use the explicit import, approve, and activate actions. Finish setup by creating the demo user:

+```bash
 go run ./cmd/admin
