CloudEdge Event Federation — checkpoint (Phase 1 + 1.5 complete)

Status: experimental (in development; NOT recommended-stable) Branch: event-federation · Checkpoint commit: 2bfd8b4d · Date: 2026-05-30

Summary​

CloudEdge Event Federation (ADR 0006) Phase 1 and the Phase 1.5 cleanup are complete on event-federation. This is the local-only foundation of the routerd-to-routerd typed event bus: an observed-fact envelope, an EventGroup Kind, a SQLite local store, and a CLI to emit/list events. No cross-node delivery yet — that is Phase 2.

What is in at this checkpoint​

  • EventGroup Kind (federation.routerd.net/v1alpha1) + validation.
  • federation.Event envelope (observed fact; not config, not a command) with Normalize/Validate/IsExpired.
  • SQLite federation_events table, idempotent RecordFederationEvent (ON CONFLICT(id) DO NOTHING), and filtered ListFederationEvents (group filter + read-time expiry filter).
  • routerctl federation event emit/list (alias fed).
  • Unit + CLI tests; ADR 0006 reconciled to reflect implemented state.

Semantics fixed here (do not regress in later phases): store idempotency is keyed on the event id; dedupeKey is a subscription-side grouping key, not a DB unique constraint in Phase 1.

Next: Phase 2 — transport only​

routerd-eventd + EventPeer push delivery over the overlay + HMAC + event_deliveries + retention prune. Explicitly out of Phase 2: EventSubscription, plugin triggering, DynamicConfigPart generation, ARP/Clients observer, and any provider mutation (those are Phase 3+).

This is a branch checkpoint note, not a release tag.
