Review R1:
- M1 (#609): DriverHostActor.StopChild releases the instance's resilience state before evicting the hub.
- m2 (#597): DriverHostActor publishes ShouldServiceAsPrimary() to IDriverPrimaryRoleSource at start and on
cluster membership changes (deduped), so the native-ack gate denies in a pair's boot window.
- m4 (#601): ApplyCachedArtifact returns false on empty/malformed bytes; the cached revision is not adopted,
Direct mode goes Stale (no RUNNING FROM CACHE), FetchAndCache lands Steady-with-no-revision and a
re-dispatch of the same revision really applies.
- m3 (#603): LocalDbReplicationPolicy splits into CapturesChanges (PeerAddress||ApiKey, registration) and
SharesRowsWithPeer (ApiKey && (PeerAddress||SyncListenPort>0), alarm drain gate).
- m5 (#618): Program.cs catch-all filters HostAbortedException (design-time tooling).
- m6 (Cluster-002): ClusterRoleInfo seeds only Up/WeaklyUp members.

Review R1 M2: since #597 the SDK timer fires at real expiry, and OnTimedUnshelve routed an operator-style
Unshelve by 'system' from both pair nodes, pre-empting the engine's AutoUnshelve. The engine owns expiry,
so the callback now routes nothing. Integration test: an engine stand-in that acts on a routed Unshelve and
expires late, plus a wrapped OnTimedUnshelve (positive control: the SDK timer fired).
Review R1 m1: Part9StateMachine.ApplyAcknowledge records a commented re-ack as AddComment (persisted and
replicated) instead of a NoOp; an uncommented re-ack is still a no-op.

Review R1 M1: StopChild evicted the hub cache, but DriverResilienceStatusPublisherService re-emits the
tracker every tick. IDriverCapabilityInvokerFactory.Release (default no-op) now invalidates the pipeline
builder + status tracker; the host calls it before Evict. Test runs a publisher tick after removal, with a
neighbour instance as positive control.

- Native-condition Acknowledge on a non-Primary node returns BadInvalidState (nothing
routed/applied/reported) via NativeAlarmAckPrimaryGate, fed from
IDriverPrimaryRoleSource by OtOpcUaServerHostedService.
- A re-ack carrying a comment reports one comment event (Acked/Confirmed unchanged).
- TimedShelve applies its requested duration and the scripted projection carries
UnshelveAtUtc, so ShelvingState/UnshelveTime counts down instead of ~24.8 days.
- Native re-ack still routed to the driver (deliberate: documented retry path), pinned.
- AdminUI /alerts client ack/shelve path test; docs/AlarmTracking.md decisions incl.
accepted SDK EventsMonitored residual (item 6).
- Also #599/03/S20: RemoveEquipmentSubtree severs inverse Organizes edges.

- AnnounceAddedNodes raises NodeAdded in the Raw realm for the existing parents of
added raw containers/tags (ComputeRawAddAnnouncements); Uns side unchanged.
- ApplyPureRemove removes UNS reference variables BEFORE the equipment subtree, so a
reference the subtree's id-prefix scope reaches no longer ratchets to a full rebuild
(03/P5). A NotSubsumed filter was not used: in production a reference NodeId is
Area/Line/Equipment/Name, outside the subtree scope, so filtering would leak it.
The matching RemoveEquipmentSubtree severing (03/S20) is in the node-manager commit.
- UnsReferenceBackingParityTests: reflection guard discovering the classifier's surgical
raw-tag whitelist and requiring a same-typed mirror field (03/U11).

STAB-21 ConnectionBackoff in EnsureConnectedAsync; STAB-22 write-pass accumulator with a

The drain gate counted SyncListenPort; a port with no ApiKey shares nothing (fail-closed
passive endpoint), and an ApiKey-only passive node shares its queue but was never gated.

LastFixedPollUtc is stamped by the fixed-tree bootstrap before any axis snapshot
is published, so under load Each_duplicate_axis_reads_its_own_position could read
inside that window and get BadNodeIdUnknown. The helper now waits for the last
axis slot plus the servo/spindle caches. 45/45 green under 14-core yes load.
