Harness: /tmp/scenario18-harness.mjs (WS-level assertion, pattern
matches #17's /tmp/call-test-harness.mjs).

- A (Pi→VM logged-out callee, Path A zero-ringee):
    terminal dm_call_undeliverable reason=no_recipient peerOrigin=VM
    elapsed 212ms (budget 2s, pre-fix 60s)
- B (VM→Pi logged-out callee, symmetric):
    elapsed 155ms, peerOrigin=Pi
- C (Path B, DM deleted on VM):
    relay hits Path B after DB delete, Bob offline,
    elapsed 140ms, reason=no_recipient
- D (group DM with online member, non-regression):
    VM accepted (Bob rung), no toast on caller
    Bob's dm_call_incoming arrived in 144ms

All payloads correct: terminal:true, phase:'start', failures[0].reason
'no_recipient', correct peerOrigin. peerLabel empty because both
instances' federation_peers.instance_name is NULL — pre-existing state,
toast code already falls back to origin hostname (not a #18 concern).

Cannot merge from agent per plan Task 10 Step 7 — coordinator's call.
