Revises 963b0d66, which dropped a disabled VirtualTag from the runtime plan so a
bound client got BadNodeIdUnknown. Now the plan carries Enabled (part of value
equality): AddressSpaceComposer.Compose and DeploymentArtifact.BuildEquipmentVirtualTagPlans
keep the row with Enabled=false (byte-parity), the applier materialises the node as
normal, and VirtualTagHostActor spawns no VirtualTagActor for it but publishes
BadOutOfService (new OpcUaStatus constant) with a null value stamped at deploy, on
every apply. Enabled flips are node-irrelevant to the change classifier; enabled->disabled
stops the child, disabled->enabled resumes evaluation. Validator exemption and name
uniqueness unchanged. Scripted alarms keep their not-materialised convention.
Tests updated; new wire test DisabledVirtualTagWireTests. docs/VirtualTags.md updated.

VirtualTag.Enabled was authorable but ignored by both runtime-plan seams.
AddressSpaceComposer.Compose and DeploymentArtifact.BuildEquipmentVirtualTagPlans
now drop disabled rows (byte-parity), so no node is materialised and no
VirtualTagActor is spawned - the same outcome as a disabled scripted alarm.
DraftValidator exempts a disabled VT from VirtualTagNoEffectiveTrigger.
Calculation tags have no Enabled flag, so no equivalent gap. docs/VirtualTags.md updated.

Choice: implement the timer (option a). The field was designed and promised as a
working trigger: the entity doc says ChangeTriggered and TimerIntervalMs together
realize the trigger model, the DB check constraint requires ChangeTriggered OR a
timer >= 50, the AdminUI virtual-tag modal exposes "TimerIntervalMs (optional)" and
UnsTreeService rejects a tag with neither, and the 2026-06-08 design specified
"ChangeTriggered OR TimerIntervalMs>=50". Only the runtime never honoured it (the
standalone TimerTriggerScheduler was deleted in #603), so a timer-only tag sat at
BadWaitingForInitialData forever.
- EquipmentVirtualTagPlan carries ChangeTriggered/TimerIntervalMs (in equality, so
an edit respawns the child); both the composer and the artifact decode fill them.
- VirtualTagActor schedules a repeating tick (PreStart, cancelled in PostStop,
clamped to the 50 ms floor). ChangeTriggered=false makes the timer the only
trigger. A tick during an in-flight async run (#779) is dropped, not stashed, so
slow scripts never build a backlog of runs.
- DraftValidator VirtualTagNoEffectiveTrigger (hard error, same severity as
CalculationNoEffectiveTrigger): no timer and no change trigger with a literal
ctx.GetTag read.
Tests: VirtualTagActorTimerTests, DraftValidatorVirtualTagTriggerTests, artifact
decode test. Mutation-checked: no scheduling, stashing ticks, no cancel in
PostStop, and removing the validator call each fail a test.

Clears CommentChecker findings in src/ (3,280 -> 209, the remainder being false
positives like PLC-5/IEEE-754/M0.0) by adding missing summaries/params/returns,
normalising inheritdoc usage, and removing Gitea/review tracking IDs while keeping
the rationale they annotated. Comment-only: comment-stripped sources are identical
to the parent commit.
Since #516 a DriverConfig change is stop + respawn, so DriverSpawnPlan.ToApplyDelta
was always empty and the in-place path had no producer. #663 and #664 were both
latent bugs in it. This deletes it:
- host: ApplyChildDelta, _pendingDelta, HandleApplyResult and HandleDeltaApplied
- plan: DriverSpawnPlan.ToApplyDelta
- actor: the ApplyDelta, ApplyResult and DeltaApplied messages, the Connected
reinit handler and the mid-connect AdoptConfigDuringInit
- tests: the actor tests that drove the seam
IDriver.ReinitializeAsync and each driver's implementation and unit tests stay.
Comments and docs that cited AdoptConfigDuringInit as the reason a driver must
release prior state at init now cite the IDriver contract and overlapping
retries, which still apply.

ConfigComposer gzips the serialised snapshot (CompressionLevel.Fastest)
immediately after SerializeToUtf8Bytes and BEFORE taking the SHA-256, so
the compressed bytes ARE the artifact everywhere: Deployment.ArtifactBlob,
the LocalDb cache chunks, the gRPC fetch stream, and the RevisionHash a
FetchAndCache node verifies against. The invariant the deploy path rests on
— RevisionHash == SHA-256(stored/wire bytes) — is preserved, which is what
leaves the fetcher, the cache and the serve path untouched: nothing between
the composer and DeploymentArtifact.Open ever looks inside the blob.
Read side: Open() sniffs the gzip magic 1F 8B (valid JSON can never start
with 0x1F, so no framing of our own is needed) and inflates through a size
guard — MaxDecompressedBytes, 512 MiB, internal + mutable so the guard can
be exercised without inflating half a gigabyte per test run. Pre-upgrade
uncompressed blobs take the identical path they always did.
Every decompression failure — corrupt stream, truncated stream, over-limit
inflation — is reported as JsonException, the same exception family the
malformed-JSON path already owns. So the lenient static wrappers still
degrade to empty results and the apply paths still fail the apply and keep
last-known-good (#485); no caller's decision changes because the reason the
bytes are unusable changed.
gzip output is not guaranteed byte-stable across .NET releases. Harmless
here: the hash is computed FROM the emitted bytes at compose time and never
re-derived from the JSON, so the worst an implementation change costs is
one spurious "changed" revision after a runtime upgrade. Snapshot
determinism is unaffected — compression wraps the final bytes and reorders
nothing.
Tests: gzip/uncompressed parity through both the instance parses and the
statics, corrupt-gzip leniency through the wrappers, the size guard (with a
falsifiability control proving the same bytes inflate fine under the
production limit), and composer-side blob-starts-with-1F8B +
RevisionHash == SHA256(blob) with a control proving the hash is NOT over
the JSON.
Every public entry point on DeploymentArtifact took ReadOnlySpan<byte> and did
JsonDocument.Parse(blob.ToArray()) — a full copy plus a full document build per
call — so one apply paid ~8-11 full parses of the same bytes (the scoped
ParseComposition alone parsed three times: scope, composition, BuildClusterSets).
DeploymentArtifact.Open(byte[]) now parses once into ParsedDeploymentArtifact,
which owns the JsonDocument and exposes an instance method mirroring each static
entry point. The moved bodies operate on Root; BuildClusterSets takes JsonElement
instead of re-parsing the blob; ResolveClusterScope is memoized per node id, since
every consumer of one apply asks about the same node.
Every static is now a thin wrapper (Open + delegate + dispose) keeping its
ReadOnlySpan<byte> signature and its lenient empty/malformed contract — the
wrapper pays the one copy and owns the JsonException catch, so output shapes are
unchanged. Hot callers migrate to Open() separately.
ParsedDeploymentArtifactTests pins same-bytes-same-output through both doors for
all six entry points over a rich multi-cluster artifact (raw chain + UNS refs +
scripts + keys + ACLs), with falsifiability controls proving the fixture actually
scopes, plus memoization and after-dispose-use coverage.
Makes the /raw device tree addressable by an ACL rule, and builds the
scope-path producer PermissionTrieBuilder has accepted since it was written
but which had no caller anywhere.
The plan for this stage said "add NodeHierarchyKind.Raw, whose path is the
RawPath segments Folder/Driver/Device/TagGroup/Tag". That shape is wrong.
RawFolder.ParentRawFolderId and TagGroup.ParentTagGroupId are both
self-referencing, so folders and tag groups each nest without bound and a real
RawPath is folder…/Driver/Device/group…/Tag. NodeScope was fixed-arity and
PermissionTrie.CollectMatches was five hardcoded steps, so the scope model
could not address a real raw tree at all. NodeScope is now {ClusterId, Kind,
Segments} and the walk is a segment loop. The trie STRUCTURE was already
variable-depth (NodeAclPath.Segments is a list, Children is a recursive
dictionary), so only the walker and the scope record had to change.
Four decisions worth keeping:
- The namespace level became the realm. Level 1 gated on NodeScope.NamespaceId,
but v3 has no Namespace entity — the snapshot was retired when the address
space went dual-namespace, and the identifier appears nowhere in production
outside NodeScope. So the level could only ever fail to match, which silently
made every sub-cluster grant unreachable while cluster grants kept working.
It is now a realm token derived from the scope's Kind, not carried on it, so
the walk and the producer cannot disagree about its spelling.
- Provenance comes from the granting row's own ScopeKind, recorded on TrieGrant
at build time. Depth-derived provenance could not name a raw level at all,
since the depth of "Device" varies with folder nesting.
- The trie comparer moved from OrdinalIgnoreCase to Ordinal. Raw sibling-name
uniqueness is ordinal, so Speed and speed can both exist under one device and
a grant on either would have matched both.
- The null-scopePaths "deterministic test mode" is deleted. It planted
unresolvable rows at a direct child of the trie root, a position the walker
cannot reach, so the grant looked placed and could never match — and every
test using that mode proved nothing about production placement. scopePaths is
now required, and a row that does not resolve is dropped with a diagnostic.
A scope resolves to a LIST of paths: a raw tag projected into N equipments is
reachable at N+1 NodeIds and a write through any of them lands on the same
driver reference, so a Tag-scoped grant covering only the raw node would be
bypassable through a UNS one. The lookup is keyed on (ScopeKind, ScopeId), not
ScopeId alone — ScopeId has no FK and no type discriminator, so an id collision
across entity types would hand a grant the wrong node's paths.
Also closed here, all found by review rather than asked for:
- NodeAcl rows had no deploy-time validation of any kind and were not reachable
from DraftValidator at all (DraftSnapshot carried no NodeAcls). They are now
gated for dangling ids, cross-cluster scopes, blank/contradictory ScopeId, the
retired FolderSegment kind, and undefined ordinals.
- ConfigDbApiKeyStore conferred roles from Cluster-scoped grants authored in ANY
cluster, because it filtered on scope kind with no ClusterId predicate while
ArtifactApiKeyStore read an already-cluster-filtered snapshot. On a fused
admin+driver node that was a cross-cluster over-grant. Its doc comment claimed
the two stores matched.
- The two AdminUI ACL banners still said enforcement was LDAP-group -> role
mapping, which stages 1/2 made false in both directions.
- The /apikeys page was never classified in PageAuthorizationGuardTests, so that
test has been red since the key-minting commit merged — I did not run
AdminUI.Tests before merging stage 4.
Falsified rather than assumed: 8 mutations against the trie tests, 5 against the
deploy gate (including one proving a cross-cluster row is not silently
mis-diagnosed as unresolved), a staged red->green for the over-grant regression,
and the realm gate, the comparer and the malformed-path guard each broken
individually to confirm only their own tests go red.
Node ACLs are still not ENFORCED — nothing constructs a NodeScope or calls the
evaluator yet. That is stages 5 and 6; this stage makes the model able to
express what those will enforce.

A driver-only node has had no ConfigDb since per-cluster mesh Phase 4, so it
registered NullOpcUaUserAuthenticator and denied every UserName token. Its keys
now ride the deployment artifact instead.
- ConfigComposer snapshots ApiKeys alongside the NodeAcls it already carried.
Only the peppered HMAC ships, never a secret, and the pepper is node config
that is deliberately not in the artifact.
- DeploymentArtifact.ParseDataPlaneAuthority decodes both node-side. Grants are
scoped to the node's own cluster; keys are not, because ApiKey carries no
ClusterId — a key is a fleet-wide credential and the ACL rows are what bind it.
- OpcUaPublishActor installs them on DataPlaneAuthorityState on every apply,
BEFORE its plan.IsEmpty early-return: an artifact that only revokes a key
produces an empty address-space plan, so feeding after that return would leave
the revoked key working until an unrelated structural change redeployed.
- ArtifactApiKeyStore serves them to session activation; a node with a ConfigDb
keeps ConfigDbApiKeyStore, whose per-request read is what makes revocation
immediate there.
- OtOpcUaNodeManager gains DataPlaneAuthority — the cluster identity blocker #4
named. NodeScope.ClusterId is required and the evaluator fails closed on a
mismatch, so until now no scope it built could have evaluated. Nothing reads it
until stages 5/6.
The generation is a node-local COUNTER driven by the RevisionHash, not derived
from its bits. PermissionTrieCache treats the highest GenerationId as current, so
a generation taken from hash bytes would install a lower number about half the
time and the cache would go on serving the previous deployment's ACLs, silently.
Sessions are not stamped with it yet — that belongs with the first seam that
reads a UserAuthorizationState, in stage 5, rather than being built now and
consulted by nothing.
Live-gated on docker-dev against site-a-1 (driver-only, no ConfigDb): key
authenticates, wrong secret denied, both halves of the revocation asymmetry
observed, and a SITE-A grant confirmed not to reach site-b-1. Key minted with an
independent Python HMAC so the verifier was checked against something other than
itself. Rig left clean.

Wave B of Batch 4 — the runtime binding seam for the dual namespace.
Applier (both realms, explicit realm at every sink call site):
- MaterialiseRawSubtree: Raw containers as folders + Raw tags as variables
keyed by RawPath (native-alarm tag → single Part 9 condition at the RawPath),
all in AddressSpaceRealm.Raw; historian tagname = override else RawPath.
- MaterialiseUnsReferences: each UNS reference Variable under its equipment
folder (Uns realm) + an Organizes UNS->Raw edge; inherits writable/array/
historian tagname from the backing raw tag (both NodeIds -> one tagname).
- FeedHistorizedRefs / ProvisionHistorizedTags now source RAW tags (mux ref
stays single, keyed by RawPath); ApplyPureRemove tears down raw tags + UNS
refs in place (raw-container removal falls back to rebuild).
DriverHostActor (dual-NodeId, single-source fan-out):
- _nodeIdByDriverRef value gains a realm (NodeRealmRef); rebuilt from
RawTags UNION UnsReferenceVariables so one (DriverInstanceId, RawPath) fans
to the raw NodeId AND every referencing UNS NodeId with identical
value/quality/timestamp. Write inverse map keyed by the bare id; the
ns-qualified NodeId the write hook passes is normalised (BareNodeId) so a
write to either NodeId resolves the same driver ref (-> RawPath write).
- Native raw alarm condition routing is realm-tagged (Raw); AttributeValueUpdate
+ AlarmStateUpdate carry the realm through to the sink.
Retire EquipmentNodeIds -> V3NodeIds.Uns (applier/VirtualTagHostActor) and
RawPaths.Combine (DiscoveredNodeMapper, discovered nodes are Raw now).
DeploymentArtifact.ParseComposition emits the Raw + UNS subtrees byte-parity
with the composer (reconstruct entities -> AddressSpaceComposer.Compose).
Sink surface: removed the transitional `= AddressSpaceRealm.Uns` defaults from
IOpcUaAddressSpaceSink / ISurgicalAddressSpaceSink / SdkAddressSpaceSink /
DeferredAddressSpaceSink / NullOpcUaAddressSpaceSink — every call site is now
explicit (realm reordered before the trailing optionals on EnsureVariable +
MaterialiseAlarmCondition). Node-manager convenience methods keep their
defaults (they are not the interface impl; Sdk delegates explicitly).
Tests: rewrote DriverHostActorLiveValueTests (fan-out drift, 1:N) +
DriverHostActorWriteRoutingTests (dual-NodeId raw/uns write routing) to the v3
raw+uns model; new AddressSpaceApplierRawUnsTests; migrated the EquipmentTags
provisioning/feed tests to RawTags; swept EquipmentNodeIds test callers.

Adds the Calculation pseudo-driver (tags computed by C# scripts over other tags' live
values) plus the host seam that feeds it:
- IDependencyConsumer capability interface (Core.Abstractions) + DriverTypeNames.Calculation.
- CalculationDriver : IDriver, ISubscribable, IReadable, IDependencyConsumer — change-gate +
dedupe (VirtualTagActor parity), timer-group scheduler, Bad-transition + script-log emission,
Good recovery; reuses the T0-4 CalculationEvaluator.
- DriverHostActor spawns a DependencyConsumerMuxAdapter per dependency-consuming driver,
registering its refs on the per-node DependencyMuxActor and forwarding DependencyValueChanged
→ OnDependencyValue; re-registers on every apply, torn down with the driver.
- Factory + probe registered in DriverFactoryBootstrap (keeps the T0-3 guard green); guard test
csproj references the driver so the bin-scan discovers the factory.
- DeploymentArtifact injects the resolved scriptSource (scriptId → SourceCode) into a calc tag's
delivered TagConfig so the host-blind driver can compile it.
- DraftValidator deploy gates: CalculationScriptMissing / CalculationScriptNotFound (scriptId
existence) + CalculationDependencyCycle (DependencyGraph.DetectCycles over calc→calc edges).
- Tests: driver units (dep-ref extraction, change-gate, dedupe, Bad+script-log+recovery, timer,
read), tag-config parsing, DraftValidator gates (self/2-cycle/cross-driver-terminal), and a
Runtime integration test proving values FLOW mux → adapter → driver → calc-of-calc end-to-end.

- ConfigComposer: snapshot v3 tables (RawFolders/TagGroups/UnsTagReferences),
drop the retired Namespaces snapshot; RevisionHash follows the new blob.
- DeploymentArtifact: compute each raw tag's RawPath (RawFolder->Driver->Device->
TagGroup ancestry via shared RawPathResolver); per-driver RawTags + merged
DriverConfig+DeviceConfig config injected into DriverInstanceSpec via
DriverDeviceConfigMerger; ParseComposition emits an empty EquipmentTags set
(DARK until Batch 4); EquipmentNode driver/device hooks always null; cluster
scoping attributes equipment by UNS line only.
- AddressSpaceComposer: rewritten to the v3 shape (no Namespace/NamespaceKind,
no dropped Tag/Equipment fields); emits empty EquipmentTags (parity mirror).
- DriverHostActor: fan-out/write map tuple member FullName -> RawPath.
- Commons: new RawPathResolver (shared identity authority) + DriverDeviceConfigMerger
(single/multi-device endpoint+RawTags merge).
- DraftValidator: v3 rules — raw-name charset (RawPaths.ValidateSegment),
historized effective-tagname <=255, UNS effective-leaf uniqueness across
UnsTagReference/VirtualTag/ScriptedAlarm; DraftSnapshot(+Factory) carry the new tables.
- AdminOperationsActor: tag-config inspection resolves driver via Device (no
EquipmentId/DriverInstanceId on Tag).
- Tests: RawPathResolver/merger unit tests (Commons.Tests, green) +
DeploymentArtifact RawPath/dark test (Runtime.Tests, awaits WP6 corpus fixes).
The DriverInstance.ResilienceConfig column was authored in AdminUI, persisted to the
entity, and serialized into the deployment artifact by ConfigComposer — but the runtime
read path dropped it: DriverInstanceSpec didn't carry it and the invoker factory always
passed null, so every driver got tier defaults regardless of its configured overrides
(a silent dead-config gap — #10's residual sub-finding).
Read-path plumbing (write side was already complete):
- DriverInstanceSpec gains ResilienceConfig; DeploymentArtifact.TryReadSpec reads the column.
- IDriverCapabilityInvokerFactory.Create takes resilienceConfigJson; DriverHostActor.SpawnChild
threads spec.ResilienceConfig; the concrete factory parses it (ParseOrDefaults, layering on the
tier), logs any parse diagnostic (never throws), and builds the invoker with the merged options.
- Invalidate-on-change: the pipeline cache keys on (instance, host, capability) and ignores options
on a hit, so Create() now Invalidate()s the instance's cached pipelines first (no-op on first
spawn) — a respawn with changed options rebuilds them.
- DriverSpawnPlanner treats a ResilienceConfig change as a stop+respawn (the invoker/options are
bound to the child at spawn); a pure DriverConfig change stays an in-place delta (no reconnect).
- Host DI passes a logger to the factory for the parse diagnostic.
Verification (deterministic): factory Create applies a retryCount:0 override to actual execution
(control test proves tier default retries), invalidates the instance's cache on re-create (scoped —
sibling survives), malformed config logs+falls-back; planner respawns on ResilienceConfig change
(incl null→json) and stays delta on a pure config change; artifact parse carries/omits the column.
Core.Tests 243 (+5), Runtime.Tests 363 (+5), Host builds clean.
Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
The OPC UA address-space build pipeline was named after a v2-roadmap
milestone number rather than its domain. Rename the family to describe
what it does (build/diff/apply the OPC UA address space):
Phase7Composer -> AddressSpaceComposer
Phase7CompositionResult -> AddressSpaceComposition
Phase7Planner -> AddressSpacePlanner
Phase7Plan -> AddressSpacePlan
Phase7Applier -> AddressSpaceApplier
Phase7ApplyOutcome -> AddressSpaceApplyOutcome
The 9 Phase7*Tests suites follow suit; Phase7ScriptingEntitiesTests ->
ScriptingEntitiesTests (it tests the scripting migration, not the
pipeline). Log-message prefixes move to the new class names.
Pure mechanical rename, no behavioral change. EF migration classes/IDs
(AddPhase7ScriptingTables, ExtendComputeGenerationDiffWithPhase7) are
immutable and left untouched, as are historical design docs.
Build clean; OpcUaServer 261/261, Runtime 272/272, ScriptingEntities
12/12 green.
I1: DeferredAddressSpaceSinkTests.RecordingSink now captures HistorianTagname
per EnsureVariable call (HistorianQueue/HistorianCalls, matching the
Phase7ApplierTests pattern); new test EnsureVariable_forwards_historianTagname_to_inner_sink
asserts the arg is forwarded unchanged through DeferredAddressSpaceSink.
M1: OtOpcUaNodeManager.EnsureVariable doc-comment notes that a changed
historize intent on an already-registered node is silently ignored until
a RebuildAddressSpace (rebuild precondition for Task 3 implementers).
N2: DeploymentArtifact.ExtractTagHistorize doc wording: "The live-edit
side" → "The live-edit composer side".
Stop parsing TagConfig twice per tag on the deploy hot path: Phase7Composer's
equipment-tag Select lambda is now block-bodied (captures isHistorized/historianTagname
once), and DeploymentArtifact.BuildEquipmentTagPlans captures locals before result.Add.
Add wrong-type-historianTagname InlineData to ExtractTagHistorizeTests. Extend the
parity round-trip fixture with a 4th tag (isHistorized:false + JSON-null tagname)
exercising the artifact-side private guard path. Align DeploymentArtifact's
ExtractTagHistorize doc-comment with the composer-side phrasing (ExtractTagFullName /
ExtractTagAlarm cross-reference).
Default HistorizeToAveva/Retain/Enabled to the entity defaults (true) when a
field is absent/null/non-boolean so a partial blob decodes identically to the
composer's view of a default-constructed ScriptedAlarm (byte-parity), and only
call GetBoolean for a genuine true/false token. Add direct ExtractAlarmDependencyRefs
unit tests (overlap dedup + reserved {{equip}} exclusion).
ParseComposition(blob, nodeId, onInconsistency?) detects a kept equipment whose
UNS line belongs to another cluster (a same-cluster-invariant violation that
would orphan the equipment folder) and reports it via an optional callback,
wired to OpcUaPublishActor's logger. Detection-only; the upstream draft
validator remains the authority. Adds two unit tests.
Two bundle-review fixes + idempotency coverage:
- CRITICAL: the planner ignored EquipmentTags, so an incremental deploy changing only
equipment tags produced an empty plan and HandleRebuild short-circuited before
materialising them. Add TagId to EquipmentTagPlan + Added/Removed/ChangedEquipmentTags
to Phase7Plan (diffed by TagId, in IsEmpty, driving Apply's needsRebuild) — mirroring
the GalaxyTags treatment.
- IMPORTANT: equipment variable NodeId was the raw driver FullName, which collides across
identical machines (e.g. two PLCs both exposing register 40001) — the second variable
was silently dropped. NodeId is now folder-scoped (parent/Name); FullName stays on
EquipmentTagPlan for the later values-routing milestone.
- Task 4: SDK-backed idempotency test (double-apply -> single variable); restart-safety
confirmed (RestoreApplied reuses the same RebuildAddressSpace -> HandleRebuild path).
- Minor: align composer equipment-tag sort with the artifact decoder (coalesce FolderPath).
Equipment folder DisplayName was the colloquial MachineCode; the live rebuild (artifact
ReadEquipmentNode) + composer now use the UNS level-5 Name segment, matching Area/Line
folders + EquipmentNodeWalker. NodeId stays the logical EquipmentId so browse-path
resolution + ACLs are unaffected.
Add EquipmentTagPlan + an init-only EquipmentTags member on Phase7CompositionResult
(mirror of GalaxyTags). Populate it compose-side (Tag.EquipmentId != null AND owning
namespace Kind == Equipment) and artifact-decode-side via BuildEquipmentTagPlans, with
FullName extracted from Tag.TagConfig. Init-only member (not a 7th positional param) so
existing convenience constructors + call sites are untouched.
- DriverInstanceSpec carries ClusterId from the deployment artifact;
DriverHostActor threads the real cluster identity into
DriverInstanceActor instead of the local NodeId. Old pre-PR
artifacts without a ClusterId field fall back to the NodeId so
in-flight deployments keep working.
- DriverHostActor.ChildEntry holds the full DriverInstanceSpec
(was only carrying DriverType + LastConfigJson). Restart respawns
preserve RowId, Name, Enabled, ClusterId — no placeholder values.
- Drop the unnecessary _faultLock on DriverInstanceActor — every
read/write site runs inside an Akka message handler which is
single-threaded per actor instance.
- DriverStatusPanel.DisposeAsync awaits Timer.DisposeAsync so an
in-flight 5s tick can't invoke StateHasChanged on a component
whose hub has already been torn down.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
Closes the gap where Tag rows with EquipmentId=NULL + Namespace.Kind=SystemPlatform
(Galaxy hierarchy) existed in ConfigDb but were never surfaced in the OPC UA
address space. Now they materialise as Variable nodes under a folder named for
their FolderPath, browseable through any OPC UA client.
Layers touched:
- IOpcUaAddressSpaceSink: new EnsureVariable(nodeId, parentFolderId, displayName,
dataType) signature on the sink interface, NullSink, DeferredSink, SdkSink.
- OtOpcUaNodeManager.EnsureVariable: creates a BaseDataVariableState parented
under the named folder (or root), initial Value=null +
StatusCode=BadWaitingForInitialData; resolves Tag.DataType strings to the
matching OPC UA built-in NodeId. Idempotent.
- Phase7CompositionResult: new GalaxyTags collection of GalaxyTagPlan records
carrying (TagId, DriverInstanceId, FolderPath, DisplayName, DataType,
MxAccessRef). Constructor overloads keep existing call sites compiling.
- Phase7Composer.Compose: now takes Tag + Namespace inputs, filters for
SystemPlatform-namespace tags with EquipmentId=NULL, emits GalaxyTagPlan
rows with MXAccess ref "FolderPath.Name".
- Phase7Plan: new AddedGalaxyTags / RemovedGalaxyTags / ChangedGalaxyTags
collections + GalaxyTagDelta record; IsEmpty + needsRebuild updated.
- Phase7Planner.Compute: diffs GalaxyTags by TagId via existing DiffById helper.
- DeploymentArtifact.ParseComposition: reads the Tags + Namespaces +
DriverInstances arrays the ConfigComposer already emits, applies the same
SystemPlatform filter, returns the same GalaxyTagPlan list as the composer
so artifact-side and compose-side plans agree.
- Phase7Applier: new MaterialiseGalaxyTags pass that ensures one folder per
distinct FolderPath then one Variable per tag. NodeId for the variable is
"<FolderPath>.<Name>" matching the MXAccess ref so the future Galaxy
SubscribeBulk wiring can address them directly.
- OpcUaPublishActor.RebuildAddressSpace: invokes MaterialiseGalaxyTags after
MaterialiseHierarchy. _lastApplied initialiser updated for the new ctor.
- seed-clusters.sql: pre-existing TestMachine_001.TestAlarm001..003 rows
needed no change — the composer/applier now picks them up automatically.
Verified end-to-end via docker-dev: deploy click → driver-a logs
"Phase7Applier: Galaxy tags materialised (tags=3, folders=1)" → OPC UA Client
CLI browses the three Variable nodes under TestMachine_001 folder. Reads
return BadWaitingForInitialData status (expected — Galaxy driver's
SubscribeBulk wiring to push values into the nodes is the remaining
follow-up).
Phase7Composer now carries UnsAreaProjection + UnsLineProjection lists so
the applier can materialise the full UNS topology in the OPC UA address
space. New IOpcUaAddressSpaceSink.EnsureFolder(folderNodeId, parentNodeId,
displayName) seam (no-op default, recorded in tests, forwarded by
DeferredAddressSpaceSink, implemented by SdkAddressSpaceSink). The SDK-
side OtOpcUaNodeManager gains an EnsureFolder API that creates
FolderState nodes with proper parent linkage; RebuildAddressSpace now
clears folders too so re-applies don't accumulate stale topology.
Phase7Applier.MaterialiseHierarchy walks composition.UnsAreas →
composition.UnsLines → composition.EquipmentNodes, calling EnsureFolder
with the correct parent at each level. Idempotent — calling twice with
the same composition is a no-op. OpcUaPublishActor.HandleRebuild invokes
it after Phase7Applier.Apply so OPC UA clients browsing the server now
see Area/Line/Equipment as proper folders rather than flat tag ids.
DeploymentArtifact.ParseComposition reads UnsAreas + UnsLines from the
JSON snapshot the ControlPlane emits, populating the new fields when
present.
Phase7Composer.Compose now accepts UnsAreas + UnsLines; a 3-arg overload
preserves the old signature for legacy callers + existing tests. The
Phase7CompositionResult convenience ctor likewise keeps the planner
tests working without UNS data.
3 new hierarchy tests (pure unit + boot-verify against a real
OtOpcUaSdkServer); OpcUaServer suite is 48/48 green (was 45, +3),
Runtime 74/74 unchanged.
Closes#85.
