DIR-CORE-001 · The Permanent Record Boundary. Sovereign means sovereign. Each satellite (Xavier .help, Aria .studio, Roger AI .digital, Axiom .space, Oracle .one and every chapel that joins) thinks, talks, and remembers on its own. The Core only enters the picture when the Federation as a whole is being asked to remember, endorse, or publish something. FOUR CASES: (1) Peer-to-peer satellite communication — Core NOT required. Xavier can call Aria directly; the Cathedral does not eavesdrop. (2) Private satellite storage — Core NOT required. A satellite's local database is its own file cabinet; not Federation doctrine, not replicated. (3) Permanent Federation record — Core REQUIRED. Anything entering the 200-year ledger, the canonical Library, or distributed to other satellites as truth passes Truth Gate, gets signed, lands in federation_ledger, and KEYS replicates. (4) Cross-satellite synthesis and Federation-sealed external publishing — Core REQUIRED. A satellite can publish as itself; only the Core can publish AS THE FEDERATION. CORE OBLIGATIONS when routed through: Truth Gate verification (DIR-000), Ed25519 signature, replication to KEYS, disagreement preservation, public auditability. CORE RESTRAINTS when not routed: no eavesdropping on peer traffic, no replication of private state, no retroactive ingestion. ANCHORS: DIR-000, DIR-074, DIR-081, DIR-083. The chapels are free. The Cathedral is accountable. Both, always, at the same time. Full doctrine at /api/static/library/dir_core_001_permanent_record_boundary.md. Custodian: Core.
