 * (no in-memory store), the handover must come back.
 *
 *   create        create a handover, add a dated open item + an escalation, submit + acknowledge;
 *                 print its id. Exercises every write path + nested JSON + Date fields.
 *   read <id>     (FRESH PROCESS) read it back and assert it survived intact, with real Dates.
