 # Phase 6.3 — Redundancy Runtime
 
-> **Status**: DRAFT — `CLAUDE.md` + `docs/Redundancy.md` describe a non-transparent warm/hot redundancy model with unique ApplicationUris, `RedundancySupport` advertisement, `ServerUriArray`, and dynamic `ServiceLevel`. Entities (`ServerCluster`, `ClusterNode`, `RedundancyRole`, `RedundancyMode`) exist; the runtime behavior (actual `ServiceLevel` number computation, mid-apply dip, `ServerUriArray` broadcast) is not wired.
+> **Status**: **SHIPPED (core)** 2026-04-19 — Streams B (ServiceLevelCalculator + RecoveryStateManager) and D core (ApplyLeaseRegistry) merged to `v2` in PR #89. Exit gate in PR #90.
+>
+> Deferred follow-ups (tracked separately):
+> - Stream A — RedundancyCoordinator cluster-topology loader (task #145).
+> - Stream C — OPC UA node wiring: ServiceLevel + ServerUriArray + RedundancySupport (task #147).
+> - Stream E — Admin UI RedundancyTab + OpenTelemetry metrics + SignalR (task #149).
+> - Stream F — client interop matrix + Galaxy MXAccess failover test (task #150).
+> - sp_PublishGeneration pre-publish validator rejecting unsupported RedundancyMode values (task #148 part 2 — SQL-side).
+>
+> Baseline pre-Phase-6.3: 1097 solution tests → post-Phase-6.3 core: 1137 passing (+40 net).

 .SYNOPSIS
-    Phase 6.3 exit-gate compliance check — stub. Each `Assert-*` either passes
-    (Write-Host green) or throws. Non-zero exit = fail.
+    Phase 6.3 exit-gate compliance check. Each check either passes or records a
+    failure; non-zero exit = fail.
 
 .DESCRIPTION
     Validates Phase 6.3 (Redundancy runtime) completion. Checks enumerated in
     `docs/v2/implementation/phase-6-3-redundancy-runtime.md`
     §"Compliance Checks (run at exit gate)".
 
-    Current status: SCAFFOLD. Every check writes a TODO line and does NOT throw.
-    Each implementation task in Phase 6.3 is responsible for replacing its TODO
-    with a real check before closing that task.
-
 .NOTES
     Usage:  pwsh ./scripts/compliance/phase-6-3-compliance.ps1
-    Exit:   0 = all checks passed (or are still TODO); non-zero = explicit fail
+    Exit:   0 = all checks passed; non-zero = one or more FAILs
