Durable hub-to-hub sync
Restart-safe per-peer mirrors, bounded concurrent drains, backoff isolation, checksummed journal segments, and fail-closed cursors.
SYNAPSE CHANNEL Fleet turns the open-source coordination Core into a durable multi-machine operating fabric—with restart-safe sync, per-peer trust, offline licence admission, and evidence that survives disconnection.
The open-source Core owns the wire protocol and federation primitives. Fleet adds the durable service, operator controls, trust lifecycle, and commercial deployment boundary.
Restart-safe per-peer mirrors, bounded concurrent drains, backoff isolation, checksummed journal segments, and fail-closed cursors.
Changed mTLS and Ed25519 trust material is validated as one immutable generation before any socket opens.
Strict versioned configuration, separate credentials and cadence, protocol negotiation, status snapshots, and a read-only doctor pass.
Named-license documents are verified locally before credentials are read or network connections begin. No account lookup or telemetry.
Remote claims route only through the configured owner; denials and malformed or expired verdicts are never cached.
Independently signed commitments let operators verify equal Core log state offline across deployment boundaries.
Fleet includes automated protocol-path and replay evidence. Physical host separation and observability captures remain explicit deployment evidence—not assumed product facts.
Durable sync and recovery, trust rotation, partition-denial replay, audit-equality verification, protocol negotiation, and OTLP export paths.
Three physically separate machines, site-specific custody, and Grafana or Jaeger views must be captured and approved for each deployment.
