Phase 6.1 exit gate — compliance script real-checks + phase doc status = SHIPPED

scripts/compliance/phase-6-1-compliance.ps1 replaces the stub TODOs with 34
real checks covering:
- Stream A: pipeline builder + CapabilityInvoker + WriteIdempotentAttribute
  present; pipeline key includes HostName (per-device isolation per decision
  #144); OnReadValue / OnWriteValue / HistoryRead route through invoker in
  DriverNodeManager; Galaxy supervisor CircuitBreaker + Backoff preserved.
- Stream B: DriverTier enum; DriverTypeMetadata requires Tier; MemoryTracking
  + MemoryRecycle (Tier C-gated) + ScheduledRecycleScheduler (rejects Tier
  A/B) + demand-aware WedgeDetector all present.
- Stream C: DriverHealthReport + HealthEndpointsHost; state matrix Healthy=200
  / Faulted=503 asserted in code; LogContextEnricher; JSON sink opt-in via
  Serilog:WriteJson.
- Stream D: GenerationSealedCache + ReadOnly marking + GenerationCacheUnavailable
  exception path; ResilientConfigReader + StaleConfigFlag.
- Stream E data layer: DriverInstanceResilienceStatus entity +
  DriverResilienceStatusTracker. SignalR/Blazor surface is Deferred per the
  visual-compliance follow-up pattern borrowed from Phase 6.4.
- Cross-cutting: full solution `dotnet test` runs; asserts 1042 >= 906
  baseline; tolerates the one pre-existing Client.CLI Subscribe flake and
  flags any new failure.

Running the script locally returns "Phase 6.1 compliance: PASS" — exit 0. Any
future regression that deletes a class or un-wires a dispatch path turns a
green check red + exit non-zero.

docs/v2/implementation/phase-6-1-resilience-and-observability.md status
updated from DRAFT to SHIPPED with the merged-PRs summary + test count delta +
the single deferred follow-up (visual review of the Admin /hosts columns).

 # Phase 6.1 — Resilience & Observability Runtime
 
-> **Status**: DRAFT — implementation plan for a cross-cutting phase that was never formalised. The v2 `plan.md` specifies Polly, Tier A/B/C protections, structured logging, and local-cache fallback by decision; none are wired end-to-end.
+> **Status**: **SHIPPED** 2026-04-19 — Streams A/B/C/D + E data layer merged to `v2` across PRs #78-82. Final exit-gate PR #83 turns the compliance script into real checks (all pass) and records this status update. One deferred piece: Stream E.2/E.3 SignalR hub + Blazor `/hosts` column refresh lands in a visual-compliance follow-up PR on the Phase 6.4 Admin UI branch.
+>
+> Baseline: 906 solution tests → post-Phase-6.1: 1042 passing (+136 net). One pre-existing Client.CLI Subscribe flake unchanged.
