+summary: >
+  OCC companion authored directly (claude-code) for OmniNode-ai/omnibase_infra PR #2727 -- node_gateway_attach_effect
+  hardening (JWKS signature verification, heartbeat/detach identity binding, atomic session-store transitions
+  via put_if_present, outage-vs-revocation circuit breaker split). Companion authored directly because
+  the event-driven occ-autobind / occ-companion-effect consumer (node_occ_companion_compute) had not produced
+  a companion PR within the CI window; the source PR's occ-autobind and occ-companion-effect commands
+  both published successfully (see command.yaml evidence below), matching the current precedent shape
+  (e.g. OCC#6392 for OMN-15937).
