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.
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 connect path was the one capability call the resilience pipeline never
saw, so a driver that could not connect contributed zero breaker input and
the /hosts resilience panel read 'All targets healthy' against a dead
endpoint. InitializeAsync now routes through the invoker as
DriverCapability.Initialize, keyed on the driver-instance id.
- No pipeline retry: the actor's RetryConnect timer is the retry loop
(parser forces retryCount overrides to 0, same funnel as write-shaped).
- Breaker threshold 2, not the Read-sized 5: the breaker samples 30 s and
the reconnect timer fires every 10 s, so at most three attempts fit one
window — threshold 5 could never open. Pinned by its own test.
- An open breaker fast-fails into the same InitializeFailed path as a real
connect failure; the 15 s break window costs at most one extra tick.
The best-effort teardown ShutdownAsync stays unwrapped.
- Companion fix: DriverCapabilityInvokerFactory.Create now invalidates the
instance's tracker snapshots with its pipelines — a respawn during an
outage discarded the only breaker whose OnClosed could clear the OPEN
flag, stranding a false 'Breaker OPEN' chip forever.
Live gate PASSED on docker-dev (image symbol-verified per container):
rtu-gate against dead 10.100.0.35:5021 opened its Initialize breaker on
both centrals with the red 'BREAKER OPEN' chip on /hosts; a socat
5021→5020 forwarder recovered it (both breakers closed within 1 s, panel
back to 'All targets healthy'); healthy MAIN-modbus recorded zero breaker
events. Full suite 50/50 green. Evidence:
docs/plans/2026-08-07-adminui-followups-and-live-gates.md §7.
The sibling of #521's DriverHostStatus, dead for exactly the same reason. Before this change the
only reference in the entire repo was the DriverInstanceResilienceStatuses DbSet declaration: no
writer, no reader, and the table empty on every deployment.
Its entity doc described two components that were never built — a HostedService sampling the
tracker every ~5 s into this table, and an AdminUI that left-joined it on DriverHostStatus for
display. There is no sampler, that join exists in no razor file, and DriverHostStatus itself was
removed in #521.
Per-cluster mesh Phase 4 also makes the design unbuildable now: AddOtOpcUaConfigDb is gated on the
admin role, so a driver-only node has no ConfigDb connection to write rows with. Any per-node
runtime-status table has this problem.
The live data was never missing — it just does not go through SQL. Resilience counters reach the
AdminUI's DriverStatusPanel as DriverResilienceStatusChanged over the driver-resilience-status
telemetry channel into the in-memory IDriverResilienceStatusStore. Verified consumed: the panel
injects the store, fed by both DriverResilienceStatusBridge (DPS) and TelemetryDialSupervisor
(gRPC).
If breaker HISTORY across a central restart is ever wanted — the one thing the last-value-only
store cannot give — it needs a CENTRAL-side writer fed by that stream, never a driver-node writer.
Keeping an empty table now bought nothing toward that.
Migration DropDriverInstanceResilienceStatusTable; the scaffolder's data-loss warning cannot bite
on a table nothing ever inserted into, and Down() recreates it exactly.
Also corrected: DriverResilienceStatusTracker's doc-comment claimed CurrentInFlight fed
DriverInstanceResilienceStatus.CurrentBulkheadDepth "until the full telemetry observer lands". The
observer landed in Phase 5; the table never had a writer.

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.
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.
Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
