60 s labelled a slow-but-clean large rebuild degraded. The deadline moves to a
shared Commons DeployTimings constant that ConfigPublishCoordinator reads, and
the node's timeout is deadline - 15 s margin, so the held ack still lands in
time. A timed-out ack's reason now says the outcome was not reported in time,
distinct from a real sink failure.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
The apply writes the node's row Applied/null before the address-space outcome
is known; central adds the reason only when it ACCEPTS the ack, so a discarded
(stale/timed-out) ack left a fused node's row reading clean. The prefix moves
to ApplyAck.DegradedReasonPrefix so both writers spell the row identically.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
A degraded rebuild advances _lastApplied (deliberately), so re-deploying the
same revision diffed to an empty plan and reported a CLEAN outcome - the
#601 're-deploy re-applies' repair path sealed green over an address space
still known partial. The publish actor now remembers that the last advance
was degraded and, on an empty plan, re-ensures the whole composition
(idempotent, no rebuild), reporting clean only when that pass is clean.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
An Applied+Degraded ack keeps NodeDeploymentState.Status = Applied with
FailureReason 'Applied degraded: <reason>' (no enum/migration change). The
deployment still seals (the revision is running; latest-sealed drives drift)
but Deployment.FailureReason names the degraded nodes and the seal logs at
Warning. Recovered from the DB on singleton failover. Old-node acks (no field,
DPS JSON or gRPC) behave exactly as before.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
DriverHostActor no longer acks Applied the moment the revision advances. It
asks OpcUaPublishActor for the outcome (RebuildAddressSpace.ReportOutcome) and
acks Applied+Degraded(reason) when the apply was degraded; a missing outcome
times out (60 s, inside the coordinator's 2 min deadline) to a degraded ack,
never a clean one. Re-dispatching a revision whose apply was degraded or is
still unconfirmed re-applies instead of taking the clean idempotent
short-circuit - that re-apply is also what repairs the degraded nodes.
Tests with a bare publish probe use a clean-outcome auto-pilot probe.

Native conditions support AddComment / commented Acknowledge, so the comment (and its
ClientUserId) is condition state the rebuild dropped. And the deferred restore report
re-stamped Time with the carried instant even when a client method call had reported a
newer event in the restore->complete window; it now reports at the node's current Time.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
ApplyAck gains trailing Degraded/DegradedReason (defaulted, so an old node's
DPS JSON or gRPC ack decodes exactly as before). mesh_transport.proto adds
ApplyAckMessage.degraded = 6 / optional degraded_reason = 7. OpcUaPublishActor
replies RebuildCompleted(Degraded, Reason) on every handler path when the
RebuildAddressSpace carries ReportOutcome.

#641 keeps the projector's prior state across a deploy instead of resetting it to the
acked default. The projector never saw a client's ack (the SDK applies it to the node and
the host only routes it), so a Clear after ack+deploy now projected Acked=false and
un-acknowledged the operator's ack - previously masked by the per-deploy reset.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
Re-review of 3de2cc3b/454775c6:
- AlarmTransitions could not reach (inactive, unacked): (active,acked)->(inactive,unacked) emitted Clear
(host stayed acked) and a first-seen cleared-unacked condition emitted nothing. The table is now total;
an exhaustive test replays every (prior, target) pair through the projector's semantics.
- The per-RawPath read-compute-emit was a lock-free TryGetValue/set across SDK publish threads; it now runs
under one lock with the projection and emission.
- Condition BRANCH events (non-null BranchId) were projected (flipping the trunk) and remembered as the ack
target (acking the branch); they are dropped. BranchId is select clause 9.
- EventId is copied, not aliased from the decoded notification.
- An unchanged state re-emitted Unspecified; it now emits nothing unless message/severity changed (an
Unspecified projects from the host projector's default after a redeploy reset it).
- Exact upstream severity rides OpcUaSeverity (#626) instead of being re-bucketed.
- ShutdownAsync no longer forgets the last-told state: a reinit re-subscribes the same set and the refresh
would otherwise re-raise every acked alarm. A CHANGED set (host rebuilt) forgets it.
ConditionRefresh: called after the alarm event item is created, after an in-place reconnect (subscriptions
found on the new session by display name, since a recreate clones them) and on RefreshRequired. Refresh
markers are never projected. BadNotSupported/BadMethodInvalid/... logs once. Wire test: a condition already
active before subscribe is reported Raise; a release+resubscribe refresh re-raises nothing (falsified by
disabling the refresh call).

The AwaitAssert lambdas returned bool into an Action, so they never waited;
the test raced the rediscovery publish (5-22% failure on base too). Make the
asserts real and drive the republish with a short health poll interval.

Found while verifying item 4 of #641. The host routes a native alarm transition
on an exact ConditionId == RawPath match (DriverHostActor.ForwardNativeAlarm),
but AbCipAlarmProjection emitted "{ref}#active" and no Kind, so every ALMD
raise/clear was dropped as "no alarm condition" — and even if routed, an
Unspecified kind projects no state change. It now reports the subscribed
reference (the RawPath) and Raise/Clear. A host test pins that a decorated id
is dropped.
FOCAS has the same id shape plus a device filter keyed by host address (a
RawPath subscription polls nothing); it needs a mapping decision and is
documented in docs/drivers/FOCAS.md rather than patched here.

DriverHostActor cleared NativeAlarmProjector's per-condition prior state on
EVERY apply, so after any deploy a driver Acknowledge of a still-active alarm
projected Active=false (writing it inactive) and a Clear of an unacknowledged
alarm projected Acked=true (silently acknowledging it). The projector is now
pruned to the conditions the new composition still carries (RetainOnly).

A full RebuildAddressSpace recreated every native Part 9 condition inactive +
acknowledged, and when the alarm-tag set was unchanged (e.g. one
UnsTagReference added to an alarm-bearing raw tag) nothing re-told the new node
its state: the host does not re-subscribe for an unchanged set, and Galaxy /
OpcUaClient have no snapshot to replay anyway. Active alarms read normal until
their next device transition.
OtOpcUaNodeManager now captures each NATIVE condition's live state (from the
node, so a client-applied ack is kept) before the rebuild clears, restores it
when the same id is re-materialised native in the same apply, and reports ONE
condition event per restored off-normal condition at the new
IOpcUaAddressSpaceSink.CompleteAddressSpaceApply (after notifier wiring).
Unclaimed captures are discarded there, so a later re-add is fresh. Quality is
carried silently for normal conditions too (it is only re-annotated on a
connectivity edge). Scripted conditions are untouched (#487 re-asserts them).
OpcUaPublishActor calls CompleteAddressSpaceApply at the end of every apply.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
OtOpcUaNodeManager.MapSeverity re-bucketed every projected severity onto the
SDK's five EventSeverity values (<800 -> 700, else 900), defeating #626's exact
OpcUaSeverity: an MTConnect Fault (800) read and evented as 900; a scripted
alarm graded 1000 published 900 while /alerts said 1000; a native Low (200)
published 300. EventSeverity merely names points on the 1..1000 scale, so the
node now carries the value clamped to 1..1000 (ToPart9Severity), at
materialise, projection and in the delta gate.
MTConnect wire test now asserts Fault ActiveState=true/Severity=800 and the
Normal clear ActiveState=false/Retain=false/Severity=800.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
EventFilter.AddSelectClause(type, "ActiveState/Id") does not split the string;
it selects a single QualifiedName named "ActiveState/Id", which no event carries.
AckedState/Id, ActiveState/Id and EnabledState/Id therefore always arrived null
and Client.CLI 'alarms' (and Client.UI) reported every alarm inactive and
unacknowledged while a direct Read said Active. Pre-existing since a2883b82;
server-side event delivery was correct (proven with two-element select clauses,
incl. after #629). Select them with explicit two-element browse paths.
Over-the-wire test drives OpcUaClientService.SubscribeAlarmsAsync against the
in-process server (native + scripted); ServerEventRig now also selects
ActiveState/Id, Severity and Retain.

- Unavailable keeps an ACTIVE condition active: quality-only BadNoCommunication; on data
return same statement => quality-only Good, Normal => Clear, different => Retrigger.
- A changed alarm reference set (alarm-bearing delta = full rebuild) clears the whole
last-told record so every active condition is re-asserted; the same set keeps it.
- Quality-only events go through the host's AlarmQualityUpdate path, never a projected
snapshot (which could ack a retained unacked condition or rewrite message/severity).
- Deterministic tie-break between equal-level conditions (ordinal nativeCode, then type).
- Dedup key is level+nativeCode+nativeSeverity+qualifier; a text-only change updates nothing.

MTConnectConditionAlarmWireTests drives a scripted Agent's Fault/Normal through the real
driver, NativeAlarmProjector and sink to a client event subscription on the raw device
folder. docs/drivers/MTConnect.md replaces 'CONDITION v1: plain String' with the alarm
mapping, opt-in authoring, multi-condition, ack, replay and comms-loss behaviour, and a
live-check recipe; EVENT vocabularies as enumerations marked won't-fix. AlarmTracking.md
lists the MTConnect source and the two new AlarmEventArgs fields.

New() ran FindNodeInAddressSpace under Lock, taking other node managers' locks (lock-order
risk); the three AlarmConditionType_ShelvingState_* ids are now a static set. Adds wire tests:
TimedShelve/Unshelve by the condition's own instance method ids (object = condition or its
ShelvingState) succeed and report, and a ShelvedStateMachineType_* id call is pinned as
BadMethodInvalid with a positive control.
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
AlarmEventArgs gains optional OpcUaSeverity (supersedes the four-bucket mapping, clamped
1..1000) and QualityStatusCode (projected onto the condition's Quality). An Unspecified-kind
event carrying a quality is a quality-only annotation: the host updates the condition but
publishes no alerts row. Both default null, so every existing native source is unchanged.

Create(assignNodeIds: true) asked CustomNodeManager2.New, whose default returns the
node's current id, so every condition child kept the type's ns=0 instance-declaration id
(or an SDK-generated ns=0 number): translate of a child path returned BadNoMatch and a
Read of a browsed child id was BadNodeIdUnknown or served from the TYPE (UnshelveTime 0
on a condition timed-shelved for a minute), bypassing the data-plane ACL.
OtOpcUaNodeManager.New now derives {conditionId}/{browsePath} in the condition's
namespace, so the ACL scope of a child is its condition's scope plus the path. The
ShelvingState methods adopt their original AlarmConditionType_ShelvingState_* id as
MethodDeclarationId so clients calling them by that id still resolve. Condition removal
and rebuild forget the whole PredefinedNodes subtree so a removed condition's children
stop answering.

DriverHostActor.StopChild released the tracker (Invalidate) and evicted the hub synchronously, but
Context.Stop is asynchronous: the stopping child's in-flight SubscribeBulk completed through its
capability invoker AFTER the release, and its RecordCallStart/RecordSuccess/RecordCallComplete
re-created the tracker entry, which DriverResilienceStatusPublisherService then re-emitted every tick
forever. Confirmed with a temporary stack capture in the tracker (removed): every post-Release write
came from DriverInstanceActor.HandleSubscribeAsync -> CapabilityInvoker.ExecuteAsync; the test failed
whenever it landed before the second publisher tick.
- DriverResilienceStatusTracker.Retire (Release) drops the id's snapshots and ignores every later
Record* for it; one guarded write path re-checks after the upsert so a write racing Retire cannot
survive it. Reinstate (called by DriverCapabilityInvokerFactory.Create) lifts it, so the same id
re-added in a later deployment records again.
- TelemetryLocalHub.Evict now also holds the id (late Health/Resilience dropped, neither cached nor
fanned out); ITelemetryLocalHub.Readmit (default no-op), called at the top of SpawnChild, lifts it.
- The removal test is now deterministic: an invoker decorator holds the child's subscribe inside the
real invoker's bracket across the removal and signals when its late writes are done (positive
control) — red 5/5 without the fix, green 20/20 with it. New unit tests for the tracker guard
(incl. a Retire race), the factory Release/Create pair, the hub hold/readmit, and a re-add-same-id
host test.

The drain gate's 'is my queue-sharing peer Primary?' used only the host of
LocalDb:Replication:PeerAddress, which the passive half (ApiKey +
SyncListenPort) does not set - so as Secondary it kept draining beside its
Primary partner and every alarm event reached the historian twice.
DriverHostActor takes a sharesAlarmQueueWithLocal predicate used when no
peer host is known; WithOtOpcUaRuntimeActors builds it
(BuildAlarmQueuePeerPredicate) for a SharesRowsWithPeer node with no
PeerAddress as 'a member of my own cluster-{ClusterId} mesh other than
me'. A node sharing no rows, or with no mesh role, gets none and keeps
draining. AlarmHistorian.md / Redundancy.md / pair-replication runbook
