 - Registry add/update commands (`jh registry config add` / `jh registry config update`) use REST API endpoint `/api/v1/registry/config/registry/{name}` (POST); the backend creates or updates based on whether the registry already exists
 - Both commands accept the full registry JSON payload via `--file <path>` or stdin; the payload `name` field identifies the registry
 - Registry add/update always poll `/api/v1/registry/config/registry/{name}/savestatus` every 3 seconds up to a 2-minute timeout
+- Registry registrator command (`jh registry registrator <name>`) uses REST API endpoint `/api/v1/registry/config/registrator/{name}` (GET) and prints the full JSON response
+- Registry registrator update command (`jh registry registrator update <name>`) uses REST API endpoint `/api/v1/registry/config/registrator/{name}` (POST); the registry name comes from the positional argument (`RegistratorInfo` has no `name` field)
+- Registrator update validates that `"email"` is non-empty when `"enabled"` is true
+- GET returns 404 "Registry not found" when no registrator has been configured for that registry yet
 - Bundle provider type automatically sets `license_detect: false` in the payload
 - Admin token list command (`jh admin token list`) uses REST API endpoint `/app/token/activelist` which requires appropriate permissions
 - Token list output is concise by default (Subject, Created By, and Expired status only); use `--verbose` flag for detailed information (signature, creation date, expiration date with estimate indicator)
