Audited the registration and mapping code of each app at its origin default branch: OtOpcUa
c904472a, MxAccessGateway de86f8b8, ScadaBridge c7d868c5, HistorianGateway 4d6a9ad (all on Health
0.3.0, all MapZbHealth with default paths: /healthz runs nothing, /health/ready and /health/active
by tag). GAPS.md now carries the verified per-endpoint coverage matrix and a SPEC-by-app table;
each current-state doc lists exactly what each endpoint runs, and HistorianGateway gets its first
current-state doc.
Recorded: mxaccessgw#206 (worker-executable + galaxy-sql readiness checks, on /health/ready) is
merged; historiangw#87 (session-pool check latches 503 until restart) is still open at 4d6a9ad.
Deferred P2 downstream probes are now per-app; ScadaBridge IActiveNodeGate unification stays
deferred (shared rule already used, only the interface is local).
