- v2-e2e.yml deleted: its `--filter Category=E2E` matches zero tests repo-wide (the
E2ETests project doesn't exist) so it reported a permanent false green; and its
docker-dev fleet binds the LAN-only shared GLAuth (10.100.0.35:3893) + builds local
images, so it isn't hosted-runner-bootable anyway. FOLLOW-UP: when a runner-reachable
fleet + a real tests/Server/...E2ETests land, add a fresh workflow WITH a zero-match
guard (fail if Category=E2E matches nothing).
- v2-ci.yml integration matrix removed: fully redundant with the unit-tests leg, which
already runs both Host.IntegrationTests + OpcUaServer.IntegrationTests under the
identical filter, fixtureless, gated at MIN_EXECUTED=1. No coverage lost. The S-2
option-#2 fixture-backed-leg follow-up is preserved as a NOTE comment in the workflow.
Header comments updated; YAML validates; jobs are now build -> unit-tests.
- pending.md, current.md: git rm --cached (untrack, keep on disk) + root-anchored
.gitignore entries — making the files' own declared 'never stage' rule true.
- looseends.md: deleted (2026-05-18 snapshot; sole open item + all follow-ups
target the retired Wonderware historian sidecar rig, moot since the gateway
cutover; recoverable from history).
- stillpending.md -> docs/plans/2026-06-18-stillpending-backlog-audit.md (git mv;
referenced by docs/Historian.md + memory index, preserved under dated-plan convention).
- HISTORIAN-GATEWAY-INTEGRATION-ISSUES.md -> docs/plans/2026-06-27-historian-gateway-integration-issues.md (git mv).
- docs/Historian.md §'Closed backlog §2 items' repointed at the archived path.
Historical docs/plans/* references to the bare stillpending.md filename are frozen
point-in-time records, left untouched per the documentation-audit convention.
The 5 Driver.Historian.Wonderware* husks are untracked bin/obj build artifacts
(0 tracked files; absent from slnx). A fresh worktree carries no untracked files,
so there is nothing to rm. Only tracked Wonderware residue is the intentional
retired doc stub + closed-review findings.md (kept). Deviation recorded in plan.
Zero-reference proof passed: no *.csproj/*.props/*.targets/*.slnx names any
of the 7 binaries; no <HintPath> element exists repo-wide. Build clean after
removal. Added lib/ to .gitignore to block re-introduction.
Out of scope: purging these from git *history* (BFG/filter-repo) is a separate,
heavier decision that rewrites every clone; this removes them from the tip only.
Re-ran all seven domain reviews at master f6eaa267 (reports rewritten in
place, each with a prior-finding status table): all 4 round-1 Criticals
verified closed; new top findings are the S7 connect-timeout OCE regression
(05/STAB-14), the ResilienceConfig operator-authorable brick (01/S-6), and
a batch of resilience-seam Mediums. 00-OVERALL.md carries the updated
maturity matrix + 12-item action list.
Adds R2-01..R2-12 design/implementation plans (one per action item, house
format + bite-sized TDD task breakdowns + co-located .tasks.json; 193 tasks,
~18-24 dev-days). STATUS.md updated: round-1 topology marked historical
(all merged+pushed), re-review findings table + plan pointers added.
Consume the published 0.2.0 gateway packages. M3 opc_quality gate checked
and CLEAR: OtOpcUa never writes HistorianHistoricalValue (uses only the
WriteLiveValues path, no opc_quality field), and every OpcQuality=0 is on
the read-side HistorianSample in test fixtures — unaffected by 0.2.0's
HistorianHistoricalValue.opc_quality proto3-optional change. Build clean;
gateway-driver 99/0 and runtime 364/0 tests pass.
- CapabilityInvoker: 3 methods that implement IDriverCapabilityInvoker now use
<inheritdoc /> instead of duplicating the interface docs (MissingInheritDoc).
- TwinCAT NativeRegistration ctor: added the 8 missing <param> tags (MissingParam).
- Stripped the arch-review bookkeeping IDs STAB-1 (IS7Plc, S7Driver) + STAB-2
(TwinCATDriver x4) from comments, keeping the descriptive text.
Left the other 86 flagged items untouched — they are checker false positives on
legitimate technical content: interface-implemented events / IEqualityComparer /
IDisposable members whose <inheritdoc/> IS correct (10 InheritDocMisused), and domain
terms the heuristic misreads as tracking IDs (IEEE-754, S7-1200/300/400/1500, PLC-5,
D2-260, S7/Melsec memory addresses, OPC UA Part 9, phase-N design-doc filename refs,
UNS level-N descriptions, and prose like 'the #1 bug source' / failover 'pick #3').
Flip the #12 rig-bug note from 'recommend fixing' to fixed: FOLLOWUP-10 + STATUS task #12
+ new branch topology row. central-1 verified booting clean with the committed compose.
The historian-gateway cutover made ServerHistorianOptions read Endpoint/ApiKey/UseTls,
but docker-dev compose still set Enabled=true with the retired Wonderware Host/Port/
SharedSecret keys → HistorianGatewayClientAdapter.Create built a Uri from an empty
Endpoint → unhandled UriFormatException crashed the Host at every bring-up, leaving
docker-dev unbootable against current code.
central-1 + central-2 now use the gateway-shape keys, DISABLED by default (the rig has no
historian gateway): Enabled=${OTOPCUA_HISTORIAN_ENABLED:-false}, Endpoint/ApiKey via env,
UseTls + AllowUntrustedServerCertificate. To enable, set OTOPCUA_HISTORIAN_ENABLED=true +
OTOPCUA_HISTORIAN_ENDPOINT + export ServerHistorian__ApiKey (never committed). Verified:
compose config valid, central-1 boots clean (no UriFormatException; OPC UA + AdminUI serving).
Found during the arch-review #10 live-gate rig session; branched off master (independent
of the archreview work).
Ran the #10 live gate: built the Host image from source (crit13 tip; Gitea feed answers
200 anonymously so restore worked), stood up the docker-dev rig, central-1 booted healthy
on the new invoker wiring. Prod DI binds the REAL DriverCapabilityInvokerFactory —
confirmed live + by a new deterministic guard (ResilienceInvokerFactoryRegistrationTests,
crit13 8a8b9ec5). The behavioral retry/breaker log-line was NOT observed: reading the
Modbus driver showed its cheap paths don't throw a wrapped exception (Discover offline,
Subscribe lazy, reads non-wrapped) — only an idempotent write-to-dead-endpoint or S7 does,
not worth the multi-dependency chase since the retry behavior is deterministically proven.
Also found a rig bug: docker-dev compose's retired Wonderware ServerHistorian keys
(Host/Port/SharedSecret, Enabled=true) crash the Host at bring-up (historian-gateway cutover
now reads Endpoint -> empty UriFormatException). Worked around with an override; recommend
fixing the committed compose. FOLLOWUP-10 + STATUS updated; crit13 topology head -> 8a8b9ec5.
AddOtOpcUaDriverFactories (the driver-node bootstrap) must bind the real
DriverCapabilityInvokerFactory — not the NullDriverCapabilityInvokerFactory
pass-through — and it must mint a real CapabilityInvoker per instance. This is the
deterministic DI half of the #10 live gate: a refactor dropping back to the
pass-through would make the whole retry/breaker/bulkhead pipeline inert in production
while every pass-through-defaulting unit test stays green. 3 tests (real factory bound,
real invoker minted, shared singletons), non-fixtured. Host.IntegrationTests.
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.
Akka.Cluster.Hosting's WithClustering enables an SBR downing provider by default
(applies SplitBrainResolverOption.Default when ClusterOptions.SplitBrainResolver is
null), which reads the pre-existing akka.conf keep-oldest block. So the cluster was
NOT running NoDowning before Critical 1 and hard-crash failover already worked — the
typed KeepOldestOption is reinforcing/explicit-in-code, not the sole activator.
Corrects the inaccurate 'HOCON inert / NoDowning / never fails over' framing in:
- ServiceCollectionExtensions.BuildClusterOptions XML comment
- akka.conf split-brain-resolver comment
- docs/Redundancy.md Split-brain section
- SplitBrainResolverActivationTests summary + assertion message (+ method rename)
No code revert (the typed option is correct belt-and-suspenders). Cluster.Tests 29/29.
Surfaced by the #9 hard-kill failover negative control.
