Merge pull request (#93) - v2 release-readiness capstone

Closes out Phase 6 with the two pieces a release engineer needs before
tagging v2 GA:

1. scripts/compliance/phase-6-all.ps1 — meta-runner that invokes every
   per-phase Phase 6.N compliance script in sequence + aggregates results.
   Each sub-script runs in its own powershell.exe child process so per-script
   $ErrorActionPreference + exit semantics can't interfere with the parent.
   Exit 0 = every phase passes; exit 1 = one or more phases failed. Prints a
   PASS/FAIL summary matrix at the end.

2. docs/v2/v2-release-readiness.md — single-view dashboard of everything
   shipped + everything still deferred + release exit criteria. Called out
   explicitly:
   - Three release BLOCKERS (must close before v2 GA):
     * Phase 6.2 Stream C dispatch wiring — AuthorizationGate exists but no
       DriverNodeManager Read/Write/etc. path calls it (task #143).
     * Phase 6.1 Stream D follow-up — ResilientConfigReader + sealed-cache
       hook not yet consumed by any read path (task #136).
     * Phase 6.3 Streams A/C/F — coordinator + UA-node wiring + client
       interop still deferred (tasks #145, #147, #150).
   - Three nice-to-haves (not release-blocking) — Admin UI polish, background
     services, multi-host dispatch.
   - Release exit criteria: all 4 compliance scripts exit 0, dotnet test ≤ 1
     known flake, blockers closed or v2.1-deferred with written decision,
     Fleet Admin signoff on deployment checklist, live-Galaxy smoke test,
     OPC UA CTT pass, redundancy cutover validated with at least one
     production client.
   - Change log at the bottom so future ships of deferred follow-ups just
     append dates + close out dashboard rows.

Meta-runner verified locally:
  Phase 6.1 — PASS
  Phase 6.2 — PASS
  Phase 6.3 — PASS
  Phase 6.4 — PASS
  Aggregate: PASS (elapsed 340 s — most of that is the full solution
  `dotnet test` each phase runs).

Net counts at capstone time: 906 baseline → 1159 passing across Phase 6
(+253). 15 deferred follow-up tasks tracked with IDs (#134-137, #143-144,
#145, #147, #149-150, #153, #155-157). v2 is NOT YET release-ready —
capstone makes that explicit rather than letting the "shipped" label on
each phase imply full readiness.

+
+## Release blockers (must close before v2 GA)
+
+Ordered by severity + impact on production fitness.
+
+### Security — Phase 6.2 dispatch wiring (task #143)
+
+The `AuthorizationGate` + `IPermissionEvaluator` + `PermissionTrie` stack is fully built and unit-tested, **but no dispatch path in `DriverNodeManager` actually calls it**. Every OPC UA Read / Write / HistoryRead / Browse / Call / CreateMonitoredItems on the live server currently runs through the pre-Phase-6.2 code path (which gates Write via `WriteAuthzPolicy` only — no per-tag ACL).
+
+Closing this requires:
+
+- Thread `AuthorizationGate` through `OpcUaApplicationHost → OtOpcUaServer → DriverNodeManager` (the same plumbing path Phase 6.1's `DriverResiliencePipelineBuilder` took).
+- Build a `NodeScopeResolver` that maps `fullRef → NodeScope` via a live DB lookup of the tag's UnsArea / UnsLine / Equipment path. Cache per generation.
+- Call `gate.IsAllowed(identity, operation, scope)` in OnReadValue / OnWriteValue / the four HistoryRead paths / Browse / Call / Acknowledge/Confirm/Shelve / CreateMonitoredItems / TransferSubscriptions.
+- Stamp MonitoredItems with `(AuthGenerationId, MembershipVersion)` per decision #153 so revoked grants surface `BadUserAccessDenied` within one publish cycle.
+- 3-user integration matrix covering each operation × allow/deny.
+
+**Strict mode default**: start lax (`Authorization:StrictMode = false`) during rollout so deployments without populated ACLs keep working. Flip to strict once ACL seeding lands for production clusters.
+
+### Config fallback — Phase 6.1 Stream D wiring (task #136)
+
+`ResilientConfigReader` + `GenerationSealedCache` + `StaleConfigFlag` all exist but nothing consumes them. The `NodeBootstrap` path still uses the original single-file `LiteDbConfigCache` via `ILocalConfigCache`; `sp_PublishGeneration` doesn't call `GenerationSealedCache.SealAsync` after commit; the Configuration read services don't wrap queries in `ResilientConfigReader.ReadAsync`.
+
+Closing this requires:
+
+- `sp_PublishGeneration` (or its EF-side wrapper) calls `SealAsync` after successful commit.
+- DriverInstance enumeration, LdapGroupRoleMapping fetches, cluster + namespace metadata reads route through `ResilientConfigReader.ReadAsync`.
+- Integration test: SQL container kill mid-operation → serves sealed snapshot, `UsingStaleConfig` = true, driver stays Healthy, `/healthz` body reflects the flag.
+
+### Redundancy — Phase 6.3 Streams A/C/F (tasks #145, #147, #150)
+
+`ServiceLevelCalculator` + `RecoveryStateManager` + `ApplyLeaseRegistry` exist as pure logic. **No code invokes them at runtime.** The OPC UA server still publishes a static `ServiceLevel`; `ServerUriArray` still carries only self; no coordinator reads cluster topology; no peer probing.
+
+Closing this requires:
+
+- `RedundancyCoordinator` singleton reads `ClusterNode` + peer list at startup (Stream A).
+- `PeerHttpProbeLoop` + `PeerUaProbeLoop` feed the calculator.
+- OPC UA node wiring: `ServiceLevel` becomes a live `BaseDataVariable` on calculator observer output; `ServerUriArray` includes self + peers; `RedundancySupport` static from `RedundancyMode` (Stream C).
+- `sp_PublishGeneration` wraps in `await using var lease = coordinator.BeginApplyLease(...)` so the `PrimaryMidApply` band fires during actual publishes.
+- Client interop matrix validation against Ignition / Kepware / Aveva OI Gateway (Stream F).
+
+### Remaining drivers (task #120)
+
+AB CIP, AB Legacy, TwinCAT ADS, FOCAS drivers are planned but unshipped. Decision pending on whether these are release-blocking for v2 GA or can slip to a v2.1 follow-up.
+
+## Nice-to-haves (not release-blocking)
+
+- **Admin UI** — Phase 6.1 Stream E.2/E.3 (`/hosts` column refresh), Phase 6.2 Stream D (`RoleGrantsTab` + `AclsTab` Probe), Phase 6.3 Stream E (`RedundancyTab`), Phase 6.4 Streams A/B UI pieces, Stream C DiffViewer, Stream D `IdentificationFields.razor`. Tasks #134, #144, #149, #153, #155, #156, #157.
+- **Background services** — Phase 6.1 Stream B.4 `ScheduledRecycleScheduler` HostedService (task #137), Phase 6.1 Stream A analyzer (task #135 — Roslyn analyzer asserting every capability surface routes through `CapabilityInvoker`).
+- **Multi-host dispatch** — Phase 6.1 Stream A follow-up (task #135). Currently every driver gets a single pipeline keyed on `driver.DriverInstanceId`; multi-host drivers (Modbus with N PLCs) need per-PLC host resolution so failing PLCs trip per-PLC breakers without poisoning siblings. Decision #144 requires this but we haven't wired it yet.
+
+## Running the release-readiness check
+
+```bash
+pwsh ./scripts/compliance/phase-6-all.ps1
+```
+
+This meta-runner invokes each `phase-6-N-compliance.ps1` script in sequence and reports an aggregate PASS/FAIL. It is the single-command verification that what we claim is shipped still compiles + tests pass + the plan-level invariants are still satisfied.
+
+Exit 0 = every phase passes its compliance checks + no test-count regression.
+
+## Release-readiness exit criteria
+
+v2 GA requires all of the following:
+
+- [ ] All four Phase 6.N compliance scripts exit 0.
+- [ ] `dotnet test ZB.MOM.WW.OtOpcUa.slnx` passes with ≤ 1 known-flake failure.
+- [ ] Release blockers listed above all closed (or consciously deferred to v2.1 with a written decision).
+- [ ] Production deployment checklist (separate doc) signed off by Fleet Admin.
+- [ ] At least one end-to-end integration run against the live Galaxy on the dev box succeeds.
+- [ ] OPC UA conformance test (CTT or UA Compliance Test Tool) passes against the live endpoint.
+- [ ] Non-transparent redundancy cutover validated with at least one production client (Ignition 8.3 recommended — see decision #85).
+
+## Change log
+
+- **2026-04-19** — Phase 6.4 data layer merged (PRs #91–92). Phase 6 core complete. Capstone doc created.
+- **2026-04-19** — Phase 6.3 core merged (PRs #89–90). `ServiceLevelCalculator` + `RecoveryStateManager` + `ApplyLeaseRegistry` land as pure logic; coordinator / UA-node wiring / Admin UI / interop deferred.
+- **2026-04-19** — Phase 6.2 core merged (PRs #84–88). `AuthorizationGate` + `TriePermissionEvaluator` + `LdapGroupRoleMapping` land; dispatch wiring + Admin UI deferred.
+- **2026-04-19** — Phase 6.1 shipped (PRs #78–83). Polly resilience + Tier A/B/C stability + health endpoints + LiteDB generation-sealed cache + Admin `/hosts` data layer all live.
