Nothing read the mapping table beyond the startup validator; v3 UNS projection is
explicit via UnsTagReference. Legacy keys in stored DriverConfig are ignored (pinned).

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.

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.

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.

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.

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.

Now that ALMD transitions route, a re-subscribe (every reconnect, every alarm-set change)
started from an empty per-subscription record and re-RAISED every still-faulted alarm,
which the host projects as Active+unacked - un-acknowledging a condition the server had
just carried across the rebuild with its client ack. The record is now driver-owned and
pruned to the new set, mirroring MTConnect's _deliveredConditions.

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.

The driver cleared its whole "last told" record whenever the subscribed alarm
set changed, assuming the rebuild that accompanies an alarm-bearing delta had
reset every condition node. The server now carries each surviving native
condition's state (acknowledgement included) across the rebuild, so re-raising a
survivor would un-acknowledge it. Only entries that left the set are dropped; a
condition that comes back later is told again onto its fresh node.

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).
Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
NativeAlarmProjector derives Active/Acked ONLY from AlarmEventArgs.Kind, and this driver
never set it - every routed event projected Unspecified, leaving the condition inactive+acked
(only Message/Severity moved). The live-gate expectation 'toggling Active as opc-plc cycles'
could not have passed. Select ActiveState/Id + AckedState/Id (two-element browse paths) and
emit the Kind sequence that moves the projector from the state last told to the host to the
event's (Raise+Acknowledge when a notification carries both).

The alarm index was keyed on ns=N strings resolved once at subscribe time, while an
in-place SDK reconnect transfers the subscription without re-running it - a remote
namespace reorder silently orphaned every alarm tag. Keys are now nsu= on both sides.
Events match the authored nodeId against the event's ConditionId first, then its
SourceNode, so several conditions on one source can be authored 1:1. Acknowledge
passes the EventId of the event that named the remembered condition (paired, so node
and EventId can never come from different conditions) instead of an empty one.

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.
