1. Call list_nodes and read the Luxembourg node (lu-cm-kg): is it live, its record and event counts, its as-of date, its regional door and the duty it serves.
2. Call resolve_issuer with "LU0569974404" (APERAM), then get_record for the match. Give me every field with its source URL and read date; leave blank what the record leaves blank.
3. Call get_signal for the same identifier and tell me the ACM-68000 signal (ACM-200 trading, ACM-403 halted, ACM-404 not on the register) and its receipt id.
