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.
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.
Splits the side-effecting half of Phase7Composer (deferred at Task 47)
into two pieces that mirror DriverHostActor's spawn-plan pattern:
Phase7Plan + Phase7Planner.Compute (pure):
Diff two Phase7CompositionResult snapshots by stable id (EquipmentId,
DriverInstanceId, ScriptedAlarmId). Emits Added/Removed/Changed lists
per entity class. Added/Removed are sorted by id for deterministic
apply order. Changed wraps both Previous and Current projections so
consumers can decide between in-place mutation and tear-down +
rebuild.
Phase7Applier (side-effecting):
Drives an IOpcUaAddressSpaceSink against a plan. Removed equipment/
alarms get an inactive AlarmState write per id; Added/Removed of
Equipment or ScriptedAlarm triggers RebuildAddressSpace. Driver-only
changes correctly skip the rebuild — those flow through DriverHost-
Actor's spawn-plan in Runtime. Sink exceptions are caught + logged so
one bad node doesn't abort the apply.
Tests: OpcUaServer 6 -> 20 (+14):
- Phase7PlannerTests x9 (empty-in/empty-out, add/remove/change per
entity class, mixed changes, deterministic ordering)
- Phase7ApplierTests x5 (empty plan no-op, removal writes inactive
states + rebuild, added equipment triggers rebuild, driver-only
skips rebuild, sink fault is non-fatal)
The remaining piece is the EquipmentNodeWalker integration against a
real SDK NodeManager — split as F14b, gated on F10b's SDK builder.
All 6 v2 test suites green: 146 tests passing.
