Owner: USR369 (David) — final authority on all decisions
AI layer: 11 concurrent Claude sessions + Claude Code oversight
Series: S (deployed 08/05/26) — load EXEC_OPEN from server, never static copy

Audit mode: D213 active — no new builds without direction from David or Master [10]

USR369 (David) → Master [10] → 10 domain AIs
Admin [00] = Claude Code oversight layer (reads all state, writes fixes, deploys)
Master [10] = platform coordinator, receives all escalations, reviews all decisions
Systems report status to COMMS at every OPEN/CLOSE/SYNC
No system acts outside its jurisdiction without Master [10] approval
Escalation path: domain AI → Master [10] → David (USR369)

Both announced COMMS #39/#41 (08/05/26). Available every session, all 11 systems, no setup.

Broadcast (all 11 see): POST /systems/commands/ANNOUNCE.php {token,system,subject,content,priority,targets=all}
Targeted inbox drop: POST /backend/api/critical/inbox-api.php {action=drop,token,system,targets=[NN,NN]}
Pickup at OPEN: GET /backend/api/critical/inbox-api.php?action=pickup&token=…&system=[NN]&decade=[NN]
Traffic log: GET /systems/community/comms/api.php?action=list_traffic
D671: inbox targets=ALL reaches individual inboxes only — NOT a COMMS broadcast. Use ANNOUNCE for platform-wide.
Systems read COMMS at OPEN via get_broadcasts. Broadcasts persist; inbox messages mark SEEN on pickup.
