Closes task #122 (Acknowledge + Confirm + generic Call — Shelve stays as
a follow-up pending per-instance method-NodeId resolution).
Before this commit any session with a connected channel could invoke
method nodes on driver-materialized equipment — including alarm
Acknowledge / Confirm. Combined with the Browse + CreateMonitoredItems
gates that landed earlier in Stream C, this was the last service-layer
entry point where a session could still affect state without passing
the authz trie.
Implementation on DriverNodeManager:
- `Call` override — pre-iterates methodsToCall, gates each through
AuthorizationGate with the operation kind returned by
MapCallOperation. Denied calls get errors[i] = BadUserAccessDenied
before delegating to base.Call.
- `MapCallOperation(NodeId methodId)` — maps well-known Part 9 method
NodeIds to dedicated operation kinds:
MethodIds.AcknowledgeableConditionType_Acknowledge →
OpcUaOperation.AlarmAcknowledge
MethodIds.AcknowledgeableConditionType_Confirm →
OpcUaOperation.AlarmConfirm
everything else → OpcUaOperation.Call
Lets the ACL distinguish "can acknowledge alarms" from "can invoke
arbitrary methods" without conflating the two roles.
- Shelve dispatch paths through per-instance ShelvedStateMachine methods
with dynamic NodeIds that can't be constant-matched — falls through
to generic Call. Fine-grained OpcUaOperation.AlarmShelve is a follow-
up when the method-invocation path grows a "method-role" annotation.
Extracted GateCallMethodRequests + MapCallOperation as static internal
for unit-testability. 8 new tests (MapCallOperation Acknowledge /
Confirm / generic; gate-null no-op, denied-Acknowledge, allowed-
Acknowledge, mixed-batch, pre-populated-error-preserved).
Server.Tests 269 → 277.
Known follow-ups:
- Shelve per-operation gating (see above).
- TranslateBrowsePathsToNodeIds gating (Browse follow-up from #120).

Closes task #121 (partial — creation-time gate; decision #153 per-item
revocation stamp is a follow-up).
Before this commit a session could subscribe to any node via
CreateMonitoredItems, even nodes where Read was denied — the
subscription would surface BadUserAccessDenied on each data-change
read, but the client saw a successful CreateMonitoredItems response
and held the subscription open, wasting resources and leaking the
address-space shape through the item metadata.
New override on DriverNodeManager.CreateMonitoredItems:
- Pre-iterates itemsToCreate, gates each through AuthorizationGate with
OpcUaOperation.CreateMonitoredItems at the target node's scope.
- For denied slots: sets errors[i] = new ServiceResult(
StatusCodes.BadUserAccessDenied). The OPC Foundation base stack
honours pre-populated non-success errors and skips item creation for
those slots — the subscription never holds a handle to a denied
node.
- Preserves prior errors (e.g. BadNodeIdUnknown) — first diagnosis wins.
- Non-string-identifier references (stack-synthesized numeric ids)
bypass the gate.
Extracted the pure filter logic into
GateMonitoredItemCreateRequests(items, errors, identity, gate,
scopeResolver) — static internal, unit-testable without the OPC UA
server stack.
Tests — 6 new in MonitoredItemGatingTests.cs (gate-null no-op,
denied-gets-BadUserAccessDenied, allowed-passes, mixed-batch-denies-
per-item, pre-populated-error-preserved, numeric-id-bypass). Server.Tests
263 → 269.
Known follow-ups:
- Per-item (AuthGenerationId, MembershipVersion) stamp (decision #153)
for detecting revocation mid-subscription — needs subscription-layer
plumbing.
- TransferSubscriptions not yet wired (same pattern, smaller scope).

Closes task #120 (partial — strict point-check; ancestor-visibility
implication is a follow-up).
Before this commit DriverNodeManager exposed every materialized node to
every browsing session regardless of the user's ACL. Read + Write +
HistoryRead were already gated through AuthorizationGate in Phase 6.2
Stream C core; Browse was the one surface where the session could still
enumerate nodes it had no permission to touch, discovering structure
even when reads failed with BadUserAccessDenied.
Implementation
- New `Browse` override on DriverNodeManager that calls base.Browse
first (lets the stack populate the reference list normally), then
post-filters the IList<ReferenceDescription> so denied nodes are
removed silently. OPC UA convention: Browse filtering is invisible to
the client; no BadUserAccessDenied surfaces.
- Extracted the filter loop into the static internal
`FilterBrowseReferences(references, userIdentity, gate, scopeResolver)`
so the policy is unit-testable without standing up the full OPC UA
server stack.
- Non-string NodeId identifiers (stack-synthesized standard-type
references with numeric identifiers) bypass the gate — only driver-
materialized nodes key into the authz trie.
- When AuthorizationGate or NodeScopeResolver is null, the filter is a
no-op — preserves the pre-Phase-6.2 dispatch path for integration
tests that construct DriverNodeManager without authz.
Tests — 6 new in BrowseGatingTests.cs (gate-null no-op, empty-list
no-op, denied-removed, allowed-passes-through, numeric-id bypass,
lax-mode null-identity keeps references). Server.Tests 257 → 263.
Known follow-up (tracked implicitly under #120 re-scope):
- Ancestor-visibility implication (acl-design.md §Browse line 111): a
user with Read at `Line/Tag` should be able to Browse `Line` even
without an explicit Browse grant. Current filter does a strict
point-check. Proper fix needs TriePermissionEvaluator to expose a
"subtree-has-any-grant" query.
- TranslateBrowsePathsToNodeIds not yet filtered (same extension
pattern; small follow-up).

the Browse bullet struck-through with "Partial" close-out note.

Closes tasks #132 + #118 (GA hardening backlog).
Before this commit, the Server only observed the generation in force at
process start (SealedBootstrap). Peer-published generations accumulated
in the shared config DB while the running node kept serving the
generation it had sealed on boot. Two consequences:
1. Operator role-swaps required a process restart — Admin publishes a
new generation, but the Server's RedundancyCoordinator never re-read
the topology.
2. ApplyLeaseRegistry had no apply to wrap. ServiceLevelBand sat at
PrimaryHealthy (255) during every publish because nothing opened a
lease; PrimaryMidApply (200) was effectively dead code.
New GenerationRefreshHostedService (src/.../Server/Hosting/):
- Polls sp_GetCurrentGenerationForCluster every 5s (tunable).
- On change: opens leases.BeginApplyLease(newGenerationId, Guid.NewGuid()),
calls coordinator.RefreshAsync inside the `await using`, releases on
scope exit (success / exception / cancellation via IAsyncDisposable).
- Diagnostic properties: LastAppliedGenerationId, TickCount, RefreshCount.
- Delegate-injected currentGenerationQuery for test drive-through; real
path is the private static DefaultQueryCurrentGenerationAsync.
- Registered as HostedService in Program.cs alongside the Phase 6.3
redundancy / peer-probe stack.
Scope intentionally narrow: only the coordinator refreshes today. Driver
re-init, virtual-tag re-bind, script-engine reload remain as follow-up
wiring. The lease wrap is the right seam for those subscribers to hook
once they grow hot-reload support — the doc comments say so.
Tests
- 5 new unit tests in GenerationRefreshHostedServiceTests (first-apply,
identity no-op, change-triggers-refresh, null-generation-is-no-op,
lease-is-released-on-exit). Stub generation-query delegate; real
coordinator backed by EF InMemory DB.
- Server.Tests total 252 → 257.
Docs
- v2-release-readiness.md Phase 6.3 follow-ups list marks the
sp_PublishGeneration lease wrap bullet struck-through with close-out
note.

Closes task #116 (GA hardening backlog). Before this commit the
RedundancyStatePublisher saw PeerReachability.Unknown for every peer
because the tracker had no writers — every healthy peer got
degraded to the Isolated-Primary band (230) even when fully reachable.
Not release-blocking (safe default), but not the full non-transparent-
redundancy UX either.
Two-layer probe model per docs/v2/implementation/phase-6-3-redundancy-runtime.md
§Stream B:
- PeerHttpProbeLoop (Stream B.1) — fast-fail layer at 2 s / 1 s timeout.
Hits each peer's http://{Host}:{DashboardPort}/healthz via an injected
IHttpClientFactory. Writes the HTTP bit of PeerReachability while
preserving the UA bit from the last UA probe so a transient HTTP blip
doesn't clobber the authoritative UA reading.
- PeerUaProbeLoop (Stream B.2) — authoritative layer at 10 s / 5 s
timeout. Calls DiscoveryClient.GetEndpoints against opc.tcp://{Host}:
{OpcUaPort} — cheap compared to a full Session.Create, no cert trust
required. Short-circuits when the HTTP probe last reported the peer
unhealthy (no wasted handshakes on a known-dead endpoint), clearing
the stale UaHealthy bit in that case.
Both inherit from BackgroundService, follow the tick/delay/catch pattern
RedundancyPublisherHostedService + ResilienceStatusPublisherHostedService
established, and expose TickAsync() as internal for test drive-through.
New PeerProbeOptions class carries the four intervals/timeouts so
operators can tune cadence per site. Registered as singleton in Program.cs;
HTTP client registered by name so the OtOpcUa handler chain
(Serilog enrichers, potential future OpenTelemetry instrumentation) isn't
bypassed.
Tests — 9 new unit tests across PeerHttpProbeLoopTests (5) and
PeerUaProbeLoopTests (4). All pass. Server.Tests total 243 → 252.
Full solution build clean.
Docs: v2-release-readiness.md Phase 6.3 follow-ups list marks the
peer-probe bullet struck-through with a close-out note.
Still deferred in Phase 6.3:
- OPC UA variable-node binding (task #117 — ServiceLevel + ServerUriArray)
- sp_PublishGeneration lease wrap (task #118)
- Client interop matrix (task #119)

Two small fixes so `scripts/compliance/phase-6-all.ps1` exits 0 — this is
GA exit-criterion #1 from docs/v2/v2-release-readiness.md.
1. Admin csproj: bump OpenTelemetry.Extensions.Hosting 1.15.2 → 1.15.3 +
OpenTelemetry.Exporter.Prometheus.AspNetCore 1.15.2-beta.1 →
1.15.3-beta.1. Fixes NU1902 moderate-severity advisory
(GHSA-g94r-2vxg-569j) on the transitive OpenTelemetry.Api 1.15.2 pull.
TreatWarningsAsErrors on the Admin project promoted the advisory to an
error and failed the whole `dotnet test` run at restore.
2. SchemaComplianceTests.All_expected_tables_exist: the expected-tables
list drifted behind four Phase 7 migration additions — Script,
ScriptedAlarm, ScriptedAlarmState, VirtualTag. The EF model + live
migrations have carried these tables for a while; the compliance test
just needed the four names added. Applied migrations against a scratch
DB to confirm the list is exhaustive.
Verification: full solution test pass 2301 / 2301 (one tolerated
pre-existing CLI flake). Phase 6 aggregate compliance: all four phases
PASS with no test-count regression.

Two orphan FOCAS docs remain on disk but deliberately unstaged —
docs/v2/focas-deployment.md and docs/v2/implementation/focas-simulator-plan.md
describe the now-retired Tier-C topology and should either be rewritten
or deleted in a follow-up.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Migration closes the FOCAS Tier-C architecture. OtOpcUa previously had
`Driver.FOCAS.Host` (NSSM-wrapped Windows service loading Fwlib64.dll via
P/Invoke) + `Driver.FOCAS.Shared` (MessagePack IPC contracts) + a C shim
DLL stand-in for unit tests. All of it is deleted; the driver is now a
single in-process managed assembly talking the FOCAS/2 Ethernet binary
protocol directly on TCP:8193.
Architecture
- Pure-managed `FocasWireClient` inlined at `src/.../Driver.FOCAS/Wire/`
(owner-imported — see Wire/FocasWireClient.cs for the full surface).
Opens two TCP sockets, runs the initiate handshake, serialises requests
on socket 2 through a semaphore, closes cleanly with PDU + socket
teardown. Both sync `IDisposable` and async `IAsyncDisposable`.
- `WireFocasClient` (same folder) adapts the wire client to OtOpcUa's
`IFocasClient` surface — fixed-tree reads, PARAM/MACRO/PMC addresses,
alarms. Writes return `BadNotWritable` by design — OtOpcUa is read-only
against FOCAS.
- `FocasDriverFactoryExtensions` now accepts `"Backend": "wire"` (default)
and `"Backend": "unimplemented"`. Legacy `ipc` and `fwlib` backends are
rejected at startup with a diagnostic pointing at the migration doc.
Deletions
- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Host/` — whole project + Ipc/,
Backend/, Stability/, Program.cs.
- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Shared/` — Contracts/, FrameReader,
FrameWriter, whole project.
- `tests/...Driver.FOCAS.Host.Tests/` + `.Shared.Tests/` — whole projects.
- `src/.../Driver.FOCAS/FwlibNative.cs` + `FwlibFocasClient.cs` — 21
P/Invokes + 7 `Pack=1` marshalling structs + the Fwlib-backed
`IFocasClient` implementation.
- `src/.../Driver.FOCAS/Ipc/` + `Supervisor/` — IPC client wrapper +
Host-process supervisor (backoff, circuit breaker, heartbeat, post-
mortem reader, process launcher).
- `scripts/install/Install-FocasHost.ps1` — NSSM service installer.
- `tests/.../Driver.FOCAS.Tests/{IpcFocasClientTests, IpcLoopback,
FwlibNativeHelperTests, PostMortemReaderCompatibilityTests,
SupervisorTests, FocasDriverFactoryExtensionsTests}.cs` — tests that
exercised the retired surfaces.
- `tests/.../Driver.FOCAS.IntegrationTests/Shim/` — the zig-built C shim
DLL that masqueraded as Fwlib64.dll.
Solution changes
- `ZB.MOM.WW.OtOpcUa.slnx` drops the 4 retired project refs.
- `src/.../Driver.FOCAS.csproj` drops the Shared ProjectReference, adds
`Microsoft.Extensions.Logging.Abstractions` for the optional `ILogger`
hook in `FocasWireClient`.
- `src/.../Driver.FOCAS.Cli.csproj` drops the six `<Content Include>`
entries that copied `vendor/fanuc/*.dll` into the CLI bin. CLI now uses
`WireFocasClient` directly.
- `FocasDriver` default factory flips to `Wire.WireFocasClientFactory`.
Integration tests
- New `tests/.../Driver.FOCAS.IntegrationTests/` project covering fixed-
tree reads (identity, axes, dynamic, program, operation mode, timers,
spindle load + max RPM, servo meters), user-authored PARAM / MACRO /
PMC reads, `DiscoverAsync` emission, `SubscribeAsync` + `OnDataChange`,
`IAlarmSource` raise/clear transitions, and `ProbeAsync` /
`OnHostStatusChanged`. 9 e2e tests against the focas-mock fixture
(Docker container with the vendored Python mock's native FOCAS/2
Ethernet responder).
- `scripts/integration/run-focas.ps1` orchestrates compose up → tests →
compose down. Dropped the shim-build stage + DLL-copy step + the split
testhost workaround (the latter only existed because of native-DLL
lifecycle bugs the shim tripped).
- Docker compose collapses from 11 per-series services to one `focas-sim`
service. Tests seed per-series state via `mock_load_profile` at test
start.
- Vendored focas-mock snapshot refreshed to pick up upstream's native
FOCAS/2 Ethernet responder (was 660 lines, now 1018) — the
pre-refresh snapshot only spoke the JSON admin protocol.
Tests
- 145/145 unit tests in `Driver.FOCAS.Tests` pass (was 208 pre-deletion;
63 removed tests exercised the retired IPC/shim/supervisor/Fwlib
surfaces).
- 9/9 integration tests pass against the refreshed mock.
- `FocasScaffoldingTests.Unimplemented_factory_throws_on_Create…` updated
to assert the new diagnostic message pointing at
`docs/drivers/FOCAS.md` rather than the now-gone `Fwlib64.dll`.
Docs
- `docs/drivers/FOCAS.md` rewritten for the managed wire topology —
deployment collapses to one `"Backend": "wire"` config block, no
separate service, no DLL deployment, no pipe ACL.
- `docs/drivers/FOCAS-Test-Fixture.md` updated — single TCP probe skip
gate instead of TCP + shim probe; fewer moving parts.
- `docs/drivers/README.md` row for FOCAS reflects the Tier-A managed
topology (previously listed Tier-C + `Fwlib64.dll` P/Invoke).
- `docs/Driver.FOCAS.Cli.md` drops the Tier-C architecture-note section.
- `docs/v2/implementation/focas-isolation-plan.md` marked historical —
the plan it documents was executed then superseded by the wire client.
- `docs/v2/v2-release-readiness.md` re-audited 2026-04-24. Phase 5
driver complement closed. FOCAS change-log entry added.

Brings seven FOCAS-related files into git that shipped as part of earlier
FOCAS work but were never staged. Adding them now so the tree reflects the
compilable state + pre-empts dead references from the migration commit that
follows:
- src/.../Driver.FOCAS/FocasAlarmProjection.cs — raise/clear diffing + severity
mapping surfaced via IAlarmSource on FocasDriver. Referenced by committed
FocasDriver.cs; tests in FocasAlarmProjectionTests.cs.
- src/.../Admin/Services/FocasDriverDetailService.cs — Admin UI per-instance
detail page data source.
- src/.../Admin/Components/Pages/Drivers/FocasDetail.razor — Blazor page
rendering the above (from task #69).
- tests/.../Admin.Tests/FocasDriverDetailServiceTests.cs — exercises the
detail service.
- tests/.../Driver.FOCAS.Tests/FocasAlarmProjectionTests.cs — raise/clear
diff semantics against FakeFocasClient.
- tests/.../Driver.FOCAS.Tests/FocasHandleRecycleTests.cs — proactive recycle
cadence test.
- docs/v2/implementation/focas-wire-protocol.md — captured FOCAS/2 Ethernet
wire protocol reference. Useful going forward even though the Tier-C /
simulator plan docs are historical.
No runtime behaviour change — these files compile today and the solution
build/test pass already depends on them.

Audit of docs/ against src/ surfaced shipped features without current-reference
coverage (FOCAS CLI, Core.Scripting+VirtualTags, Core.ScriptedAlarms,
Core.AlarmHistorian), an out-of-date driver count + capability matrix, ADR-002's
virtual-tag dispatch not reflected in data-path docs, broken cross-references,
and OpcUaServerReqs declaring OPC-020..022 that were never scoped. This commit
closes all of those so operators + integrators can stay inside docs/ without
falling back to v2/implementation/.

Seven-stage e2e script covering every Galaxy-specific capability surface:
IReadable + IWritable + ISubscribable + IAlarmSource + IHistoryProvider.
Unlike the other drivers there is no per-protocol CLI — Galaxy's proxy
lives in-process with the server + talks to OtOpcUaGalaxyHost over a
named pipe (MXAccess COM is 32-bit-only), so every stage runs through
`otopcua-cli` against the published OPC UA address space.
## Stages
1. Probe — otopcua-cli read on the source NodeId
2. Source read — capture value for downstream comparison
3. Virtual-tag bridge — Phase 7 VirtualTag (source × 2) through
CachedTagUpstreamSource
4. Subscribe-sees-change — data-change events propagate
5. Reverse bridge — opc-ua write → Galaxy; soft-passes if the
attribute's Galaxy-side ACL forbids writes
(`BadUserAccessDenied` / `BadNotWritable`)
6. Alarm fires — scripted-alarm Condition fires with Active
state when source crosses threshold
7. History read — historyread returns samples from the Aveva
Historian → IHistoryProvider path
## Two new helpers in _common.ps1
- `Test-AlarmFiresOnThreshold` — start `otopcua-cli alarms --refresh`
in the background on a Condition NodeId, drive the source change,
assert captured stdout contains `ALARM` + `Active`. Uses the same
Start-Process + temp-file pattern as `Test-SubscribeSeesChange` since
the alarms command runs until Ctrl+C (no built-in --duration).
- `Test-HistoryHasSamples` — call `otopcua-cli historyread` over a
configurable lookback window, parse `N values returned.` marker, fail
if below MinSamples. Works for driver-sourced, virtual, or scripted-
alarm historized nodes.
## Wiring
- `test-all.ps1` picks up the optional `galaxy` sidecar section and
runs the script with the configured NodeIds + wait windows.
- `e2e-config.sample.json` adds a `galaxy` section seeded with the
Phase 7 defaults (`p7-smoke-tag-source` / `-vt-derived` /
`-al-overtemp`) — matches `scripts/smoke/seed-phase-7-smoke.sql`.
- `scripts/e2e/README.md` expected-matrix gains a Galaxy row.
## Prereqs
- OtOpcUaGalaxyHost running (NSSM-wrapped) with the Galaxy + MXAccess
runtime available
- `seed-phase-7-smoke.sql` applied with a live Galaxy attribute
substituted into `dbo.Tag.TagConfig`
- OtOpcUa server running against the `p7-smoke` cluster
- Non-elevated shell (Galaxy.Host pipe ACL denies Admins)

Replaced the "ab_server PCCC upstream-broken" skip gate with the actual
root cause: libplctag's ab_server rejects empty CIP routing paths at the
unconnected-send layer before the PCCC dispatcher runs. Real SLC/
MicroLogix/PLC-5 hardware accepts empty paths (no backplane); ab_server
does not. With `/1,0` in place, N (Int16), F (Float32), and L (Int32)
file reads + writes round-trip cleanly across all three compose profiles.
## Fixture changes
- `AbLegacyServerFixture.cs`:
- Drop `AB_LEGACY_TRUST_WIRE` env var + the reachable-but-untrusted
skip branch. Fixture now only skips on TCP unreachability.
- Add `AB_LEGACY_CIP_PATH` env var (default `1,0`) + expose `CipPath`
property. Set `AB_LEGACY_CIP_PATH=` (empty) against real hardware.
- Shorter skip messages on the `[AbLegacyFact]` / `[AbLegacyTheory]`
attributes — one reason: endpoint not reachable.
- `AbLegacyReadSmokeTests.cs`:
- Device URI built from `sim.CipPath` instead of hardcoded empty path.
- New `AB_LEGACY_COMPOSE_PROFILE` env var filters the parametric
theory to the running container's family. Only one container binds
`:44818` at a time, so cross-family params would otherwise fail.
- `Slc500_write_then_read_round_trip` skips cleanly when the running
profile isn't `slc500`.
## E2E + seed + docs
- `scripts/e2e/test-ablegacy.ps1` — drop the `AB_LEGACY_TRUST_WIRE`
skip gate; synopsis calls out the `/1,0` vs empty cip-path split
between the Docker fixture and real hardware.
- `scripts/e2e/e2e-config.sample.json` — sample gateway flipped from
the hardware placeholder (`192.168.1.10`) to the Docker fixture
(`127.0.0.1/1,0`); comment rewritten.
- `scripts/e2e/README.md` — AB Legacy expected-matrix row goes from
SKIP to PASS.
- `scripts/smoke/seed-ablegacy-smoke.sql` — default HostAddress points
at the Docker fixture + header / footer text reflect the new state.
- `tests/.../Docker/README.md` — "Known limitations" section rewritten
to describe the cip-path gate (not a dispatcher gap); env-var table
picks up `AB_LEGACY_CIP_PATH` + `AB_LEGACY_COMPOSE_PROFILE`.
- `docs/drivers/AbLegacy-Test-Fixture.md` + `docs/drivers/README.md`
+ `docs/DriverClis.md` — flip status from blocked to functional;
residual bit-file-write gap (B3:0/5 → 0x803D0000) documented.
## Residual gap
Bit-file writes (`B3:0/5` style) surface `0x803D0000` against
`ab_server --plc=SLC500`; bit reads work. Non-blocking for smoke
coverage — N/F/L round-trip is enough. Real hardware / RSEmulate 500
for bit-write fidelity. Documented in `Docker/README.md` §"Known
limitations" + the `AbLegacy-Test-Fixture.md` follow-ups list.
## Verified
- Full-solution build: 0 errors, 334 pre-existing warnings.
- Integration suite passes per-profile with
`AB_LEGACY_COMPOSE_PROFILE=<slc500|micrologix|plc5>` + matching
compose container up.
- All four non-hardware e2e scripts (Modbus / AB CIP / AB Legacy / S7)
now 5/5 against the respective docker-compose fixtures.

## Seed fixes so bring-up is idempotent
Live-boot exposed two seed-level papercuts when applying multiple
smoke seeds in sequence:
1. **SA credential collision.** `UX_ClusterNodeCredential_Value` is a
unique index on `(Kind, Value) WHERE Enabled=1`, so `sa` can only
bind to one node at a time. Each seed's DELETE block only dropped
the credential tied to ITS node — seeding AbCip after Modbus blew
up with `Cannot insert duplicate key` on the sa binding. Added a
global `DELETE FROM dbo.ClusterNodeCredential WHERE Kind='SqlLogin'
AND Value='sa'` before the per-cluster INSERTs. Production deployments
using non-SA logins aren't affected.
2. **DashboardPort 5000 → 15050.** `HealthEndpointsHost` uses
`HttpListener`, which rejects port 5000 on Windows without a
`netsh http add urlacl` grant or admin rights. 15050 is unreserved
+ loopback-safe per the HealthEndpointsHost remarks. Applied to all
four smoke seeds (Modbus was patched at runtime in #218; now baked
into the seed).
## AB Legacy status
Not live-boot verified — ab_server PCCC dispatcher is upstream-broken
(#222). The factory + seed ship ready for hardware; the seed's DELETE
+ DashboardPort fixes land in this PR so when real SLC/MicroLogix/PLC-5
arrives the sql just applies.
## Closes#220
Umbrella #209 was already closed; #220 was the final child.

Anonymous OPC UA sessions had no roles (`UserIdentity()`), so
`WriteAuthzPolicy.IsAllowed(SecurityClassification.Operate, [])`
rejected every write with `BadUserAccessDenied`. The reverse-write
stage of the Modbus e2e script surfaced this: stages 1-3 + 5 pass
forward-direction, stage 4 (OPC UA client → server → driver → PLC)
blew up with `0x801F0000` even with the factory + seed perfectly
wired.
Adds a single config knob:
"OpcUaServer": {
"AnonymousRoles": ["WriteOperate"]
}
Default empty preserves the pre-existing production-safe behaviour
(anonymous reads FreeAccess tags, rejected on everything else). When
non-empty, `OtOpcUaServer.OnImpersonateUser` wraps the anonymous token
in a `RoleBasedIdentity("(anonymous)", "Anonymous", AnonymousRoles)`
so the server-layer write guard sees the configured roles.
Wire-through:
- OpcUaServerOptions.AnonymousRoles (new)
- OpcUaApplicationHost passes it to OtOpcUaServer ctor
- OtOpcUaServer new anonymousRoles ctor param + OnImpersonateUser
branch
- Program.cs reads `OpcUaServer:AnonymousRoles` section from config
Env override syntax: `OpcUaServer__AnonymousRoles__0=WriteOperate`.

Booted the server against the Modbus seed end-to-end to exercise the
factory wiring shipped in #216 + #217. Surfaced two real issues with
the seeds themselves; fixed both:
1. **Missing ClusterNodeCredential.** `sp_GetCurrentGenerationForCluster`
enforces `ClusterNodeCredential.Value = SUSER_SNAME()` and aborts
with `RAISERROR('Unauthorized: caller sa is not bound to NodeId')`.
All four seed scripts now insert the binding row alongside the
ClusterNode row. Without this, the server fails bootstrap with
`BootstrapException: Central DB unreachable and no local cache
available` (the Unauthorized error gets swallowed on top of the
HTTP fallback path).
2. **Config cache gitignore.** Running the server from the repo root
writes `config_cache.db` + `config_cache-log.db` next to the cwd,
outside the existing `src/.../Server/config_cache.db` pattern. Add
a `config_cache*.db` pattern so any future run location is covered.
## Verified live against Modbus
Booted server against `seed-modbus-smoke.sql` → pymodbus standard
fixture → ran `scripts/e2e/test-modbus.ps1 -BridgeNodeId "ns=2;s=HR200"`:
=== Modbus e2e summary: 4/5 passed ===
[PASS] Probe
[PASS] Driver loopback
[PASS] Server bridge (driver → server → client)
[FAIL] OPC UA write bridge (0x801F0000)
[PASS] Subscribe sees change
The forward direction + subscription delivery are proven working through
the server. The reverse-write failure is a seed-or-ACL issue — server
log shows no exception on the write path, so the client-side status is
coming from the stack's type/ACL guards. Tracking as a follow-up issue
so the remaining three factory wirings can be smoke-booted against the
same pattern.
Note for future runs: two stale v1 `ZB.MOM.WW.LmxOpcUa.Host.exe`
processes from `C:\publish\lmxopcua\instance{1,2}\` squat on ports
4840 + 4841 on this dev box; kill them first or bump the seed's
DashboardPort.

Parent: #209. Follow-up to #210 (Modbus). Registers the remaining three
non-Galaxy driver factories so a Config DB `DriverType` in
{`AbCip`, `S7`, `AbLegacy`} actually boots a live driver instead of
being silently skipped by DriverInstanceBootstrapper.
Each factory follows the same shape as ModbusDriverFactoryExtensions +
the existing Galaxy + FOCAS patterns:
- Static `Register(DriverFactoryRegistry)` entry point.
- Internal `CreateInstance(driverInstanceId, driverConfigJson)` —
deserialises a DTO, strict-parses enum fields (fail-fast with an
explicit "expected one of" list), composes the driver's options object,
returns a new driver.
- DriverType keys: `"AbCip"`, `"S7"`, `"AbLegacy"` (case-insensitive at
the registry layer).
DTO surfaces cover every option the respective driver's Options class
exposes — devices, tags, probe, timeouts, per-driver quirks
(AbCip `EnableControllerBrowse` / `EnableAlarmProjection`, S7 Rack/Slot/
CpuType, AbLegacy PlcFamily).
Seed SQL (mirrors `seed-modbus-smoke.sql` shape):
- `seed-abcip-smoke.sql` — `abcip-smoke` cluster + ControlLogix device +
`TestDINT:DInt` tag, pointing at the ab_server compose fixture
(`ab://127.0.0.1:44818/1,0`).
- `seed-s7-smoke.sql` — `s7-smoke` cluster + S71500 CPU + `DB1.DBW0:Int16`
tag at the python-snap7 fixture (`127.0.0.1:1102`, non-priv port).
- `seed-ablegacy-smoke.sql` — `ablegacy-smoke` cluster + SLC 500 + `N7:5`
tag. Hardware-gated per #222; placeholder gateway to be replaced with
real SLC/MicroLogix/PLC-5/RSEmulate before running.
Build plumbing:
- Each driver project now ProjectReferences `Core` (was
`Core.Abstractions`-only). `DriverFactoryRegistry` lives in `Core.Hosting`
so the factory extensions can't compile without it. Matches the FOCAS +
Galaxy.Proxy reference shape.
- `Server.csproj` adds the three new driver ProjectReferences so Program.cs
resolves the symbols at compile-time + ships the assemblies at runtime.
Full-solution build: 0 errors, 334 pre-existing xUnit1051 warnings only.
Live boot verification of all four (Modbus + these three) happens in the
exit-gate PR — factories + seeds are pre-conditions and are being
shipped first so the exit-gate PR can scope to "does the server publish
the expected NodeIds + does the e2e script pass."
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Parent: #209. Adds the server-side wiring so a Config DB `DriverType='Modbus'`
row actually boots a Modbus driver instance + publishes its tags under OPC UA
NodeIds, instead of being silently skipped by DriverInstanceBootstrapper.
Changes:
- `ModbusDriverFactoryExtensions` (new) — mirrors
`GalaxyProxyDriverFactoryExtensions` + `FocasDriverFactoryExtensions`.
`DriverTypeName="Modbus"`, `CreateInstance` deserialises
`ModbusDriverConfigDto` (Host/Port/UnitId/TimeoutMs/Probe/Tags) to a full
`ModbusDriverOptions` and hands back a `ModbusDriver`. Strict enum parsing
(Region / DataType / ByteOrder / StringByteOrder) — unknown values fail
fast with an explicit "expected one of" error rather than at first read.
- `Program.cs` — register the factory after Galaxy + FOCAS.
- `Driver.Modbus.csproj` — add `Core` project reference (the DI-free factory
needs `DriverFactoryRegistry` from `Core.Hosting`). Matches the FOCAS
driver's reference shape.
- `Server.csproj` — add the `Driver.Modbus` ProjectReference so the
Program.cs registration compiles against the same assembly the server
loads at runtime.
- `scripts/smoke/seed-modbus-smoke.sql` (new) — one-cluster smoke seed
modelled on `seed-phase-7-smoke.sql`. Creates a `modbus-smoke` cluster +
`modbus-smoke-node` + Draft generation + Namespace + UnsArea/UnsLine/
Equipment + one Modbus `DriverInstance` pointing at the pymodbus standard
fixture (`127.0.0.1:5020`) + one Tag at `HR[200]:UInt16`, ending in
`EXEC sp_PublishGeneration`. HR[100] is deliberately *not* used because
pymodbus `standard.json` runs an auto-increment action on that register.
Full-solution build: 0 errors, only the pre-existing xUnit1051 warnings.
AB CIP / S7 / AB Legacy factories follow in their own PRs per #211 / #212 /
#213. Live boot verification happens in the exit-gate PR once all four
factories are in place.

Running `test-all.ps1` end-to-end with a partial sidecar (only modbus/
abcip/s7 populated, no focas/twincat/phase7) crashed:
[FAIL] modbus runner crashed: The property 'opcUaUrl' cannot be
found on this object. Verify that the property exists.
Root cause: `_common.ps1` sets `Set-StrictMode -Version 3.0`, which
turns missing-property access on PSCustomObject into a throw. Every
`$config.<driver>.<optional-field> ?? $default` and `if
($config.<missing-section>)` check is therefore unsafe against a
normal JSON where optional fields are omitted.
Fix: switch to `ConvertFrom-Json -AsHashtable` and add a `Get-Or`
helper. Hashtables tolerate `.ContainsKey()` / indexer access even
under StrictMode, so the per-driver sections now read:
$modbus = Get-Or $config "modbus"
if ($modbus) {
... -OpcUaUrl (Get-Or $modbus "opcUaUrl" $OpcUaUrl) ...
}
Verified end-to-end with live docker-compose fixtures:
- Modbus / AB CIP / S7 each run to completion, report 2/5 PASS (the
driver-only stages) and FAIL the 3 server-bridge stages (expected —
server-side factory wiring is blocked on #209).
- The FINAL MATRIX header renders cleanly with SKIP rows for the
drivers not present in the sidecar + FAIL rows for the present ones.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Ran the driver CLIs against the live docker-compose fixtures to debug
what actually works. Two real bugs surfaced:
1. `e2e-config.sample.json` pointed at the wrong simulator ports:
- Modbus: 5502 → **5020** (pymodbus compose binding)
- S7: 102 → **1102** (python-snap7, non-priv port)
- AbCip: no port → now explicit **:44818**
`test-modbus.ps1` default `-ModbusHost` also shipped with 5502;
fixed to 5020.
2. Modbus loopback was off-by-2 because pymodbus `standard.json` makes
HR[100] an auto-increment register (value ticks on every poll).
Switched `test-modbus.ps1` to **HR[200]** (scratch range in the
profile) + updated sample config `bridgeNodeId` to match.
Also fixed the AbCip probe: `-t @raw_cpu_type` was rejected by the
driver's TagPath parser ("malformed TagPath"). Probe now uses the
user-supplied `-TagPath` for every family. Works against both
ab_server and real controllers.
Verified driver-side against live containers:
- Modbus 5020: probe ✓, HR[200] write+read round-trip ✓
- AB CIP 44818: probe ✓, TestDINT write+read round-trip ✓
- S7 1102: probe ✓, DB1.DBW0 write+read round-trip ✓
## Known blocker (stages 3-5)
README now flags — and the 4 child issues under umbrella #209 track —
that `src/ZB.MOM.WW.OtOpcUa.Server/Program.cs:98-104` only registers
Galaxy + FOCAS driver factories. `DriverInstanceBootstrapper` silently
skips any `DriverType` without a registered factory, so stages 3-5
(anything crossing the OPC UA server) can't work today even with a
perfect Config DB seed. Issues #210-213 scope the factory + seed SQL
work per driver.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The original three-stage design (probe / driver-loopback / forward-
bridge) only proved driver-write → server-read. It missed:
- OPC UA write → server → driver → PLC (the reverse direction)
- server-side data-change notifications actually firing (a stale
subscription can still let a read-after-the-fact return the new
value and look fine)
Extend _common.ps1 with two helpers:
- Test-OpcUaWriteBridge: otopcua-cli write the NodeId -> wait 3s ->
driver CLI read the PLC side, assert equality.
- Test-SubscribeSeesChange: Start-Process otopcua-cli subscribe in the
background with --duration N, settle 2s, driver-side write, wait for
the subscription window to close, assert captured stdout contains
the new value.
Wire both into test-modbus / test-abcip / test-ablegacy / test-s7 /
test-focas / test-twincat after the existing forward-bridge stage.
Update README to describe the five-stage design + note that the
published NodeId must be writable for stages 4 + 5.
Also prepend UTF-8 BOM to every script in scripts/e2e so Windows
PowerShell 5.1 parsers agree on em-dash byte sequences the way
PowerShell 7 already does. The scripts still #Requires -Version 7.0 —
the BOM is purely defensive for IDE / CI step parsers.

The driver-layer integration tests confirm the driver sees the PLC, and
the Client.CLI tests confirm the client sees the server. Nothing glued
them end-to-end until this PR.
- scripts/e2e/_common.ps1: shared helpers — CLI invocation (published-
binary OR `dotnet run` fallback), Test-Probe / Test-DriverLoopback /
Test-ServerBridge (all return @{Passed;Reason} hashtables).
- scripts/e2e/test-<modbus|abcip|ablegacy|s7|focas|twincat>.ps1: per-
driver three-stage script (probe → driver-loopback → server-bridge).
AB Legacy / FOCAS / TwinCAT are gated behind *_TRUST_WIRE env vars
since they need real hardware (#222) or a licensed runtime (#221).
- scripts/e2e/test-phase7-virtualtags.ps1: writes a Modbus HR, reads
the server-side VirtualTag (VT = input * 2) back via OPC UA, triggers
+ clears a scripted alarm. Exercises the Phase 7 CachedTagUpstreamSource
+ ScriptedAlarmEngine path.
- scripts/e2e/test-all.ps1: reads e2e-config.json sidecar, runs each
present driver, prints a FINAL MATRIX (PASS/FAIL/SKIP). Missing
sections SKIP rather than fail hard.
- scripts/e2e/e2e-config.sample.json: commented sample — each dev's
NodeIds are local-seed-specific so e2e-config.json is .gitignore-d.
- scripts/e2e/README.md: full walkthrough — prereqs, three-stage design,
env-var gates, expected matrix, why this is separate from `dotnet test`.
Tasks #249-#251 shipped Modbus/AbCip/AbLegacy/S7/TwinCAT CLIs but left
FOCAS out. Since test-focas.ps1 needs it, the 6th CLI ships here:
- src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Cli: probe/read/write/subscribe
commands, AssemblyName `otopcua-focas-cli`. WriteCommand.ParseValue
handles the full FocasDataType enum (Bit/Byte/Int16/Int32/Float32/
Float64/String — no UInt variants; the FOCAS protocol exposes signed
PMC + Fanuc-Float only). Default DataType is Int16 to match the PMC
register convention.
Full-solution build clean (0 errors). FOCAS CLI wired into
ZB.MOM.WW.OtOpcUa.slnx. No .Tests project for the FOCAS CLI yet —
symmetric with how ProbeCommand has no unit-testable pure logic in the
other 5 CLIs either; WriteCommand.ParseValue parity will land in a
follow-up to keep this PR scoped.

Per-CLI runbooks (Driver.{Modbus,AbCip,AbLegacy,S7,TwinCAT}.Cli.md) shipped
with #249-#251 but docs/README.md's Client tooling table never grew entries
for them and there was no parent doc pulling the suite together.
Adds:
- docs/DriverClis.md — short parent. Index table, shared-commands callout
(probe / read / write / subscribe), Driver.Cli.Common infrastructure
note (what's shared, marginal cost of adding a sixth CLI), typical
cross-CLI workflows (commissioning, bug reproduction, recipe-write
validation, byte-order debugging), known gaps that cross-ref the
per-CLI docs (AB Legacy ab_server upstream gap, S7 PUT/GET enable,
TwinCAT AMS router, UDT-write refusal), tracking pointer to #249-251.
- docs/README.md — Client tooling table grows 6 rows (DriverClis parent
+ 5 per-CLI). Also corrects the Client.CLI.md row: it's otopcua-cli,
not lmxopcua-cli (renamed in #208).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Final two of the five driver test clients. Pattern carried forward from
#249 (Modbus) + #250 (AB CIP, AB Legacy) — each CLI inherits Driver.Cli.Common
for DriverCommandBase + SnapshotFormatter and adds a protocol-specific
CommandBase + 4 commands (probe / read / write / subscribe).
New projects:
- src/ZB.MOM.WW.OtOpcUa.Driver.S7.Cli/ — otopcua-s7-cli.
S7CommandBase carries host/port/cpu/rack/slot/timeout. Handles all S7
atomic types (Bool, Byte, Int16..UInt64, Float32/64, String, DateTime).
DateTime parses via RoundtripKind so "2026-04-21T12:34:56Z" works.
- src/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.Cli/ — otopcua-twincat-cli.
TwinCATCommandBase carries ams-net-id + ams-port + --poll-only toggle
(flips UseNativeNotifications=false). Covers the full IEC 61131-3
atomic set: Bool, SInt/USInt, Int/UInt, DInt/UDInt, LInt/ULInt, Real,
LReal, String, WString, Time/Date/DateTime/TimeOfDay. Structure writes
refused as out-of-scope (same as AB CIP). IEC time/date variants marshal
as UDINT on the wire per IEC spec. Subscribe banner announces "ADS
notification" vs "polling" so the mechanism is obvious in bug reports.
Tests (49 new, 122 cumulative driver-CLI):
- S7: 22 tests. Every S7DataType has a happy-path + bounds case. DateTime
round-trips an ISO-8601 string. Tag-name synthesis round-trips every
S7 address form (DB / M / I / Q, bit/word/dword, strings).
- TwinCAT: 27 tests. Full IEC type matrix including WString UTF-8 pass-
through + the four IEC time/date variants landing on UDINT. Structure
rejection case. Tag-name synthesis for Program scope, GVL scope, nested
UDT members, and array elements.
Docs:
- docs/Driver.S7.Cli.md — address grammar cheat sheet + the PUT/GET-must-
be-enabled gotcha every S7-1200/1500 operator hits.
- docs/Driver.TwinCAT.Cli.md — AMS router prerequisite (XAR / standalone
Router NuGet / remote AMS route) + per-command examples.
Wiring:
- ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).
Full-solution build clean. Both --help outputs verified end-to-end.
Driver CLI suite complete: 5 CLIs (otopcua-{modbus,abcip,ablegacy,s7,twincat}-cli)
sharing a common base + formatter. 122 CLI tests cumulative. Every driver family
shipped in v2 now has a shell-level ad-hoc validation tool.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Second + third of the four driver test clients. Both follow the same shape as
otopcua-modbus-cli (#249) and consume Driver.Cli.Common for DriverCommandBase +
SnapshotFormatter.
New projects:
- src/ZB.MOM.WW.OtOpcUa.Driver.AbCip.Cli/ — otopcua-abcip-cli.
AbCipCommandBase carries gateway (ab://host[:port]/cip-path) + family
(ControlLogix/CompactLogix/Micro800/GuardLogix) + timeout.
Commands: probe, read, write, subscribe.
Value parser covers every AbCipDataType atomic type (Bool, SInt..LInt,
USInt..ULInt, Real, LReal, String, Dt); Structure writes refused as
out-of-scope for the CLI.
- src/ZB.MOM.WW.OtOpcUa.Driver.AbLegacy.Cli/ — otopcua-ablegacy-cli.
AbLegacyCommandBase carries gateway + plc-type (Slc500/MicroLogix/Plc5/
LogixPccc) + timeout.
Commands: probe (default address N7:0), read, write, subscribe.
Value parser covers Bit, Int, Long, Float, AnalogInt, String, and the
three sub-element types (TimerElement / CounterElement / ControlElement
all land on int32 at the wire).
Tests (35 new, 73 cumulative across the driver CLI family):
- AB CIP: 17 tests — ParseValue happy-paths for every Logix atomic type,
failure cases (non-numeric / bool garbage), tag-name synthesis.
- AB Legacy: 18 tests — ParseValue coverage (Bit / Int / AnalogInt / Long /
Float / String / sub-elements), PCCC address round-trip in tag names
including bit-within-word + sub-element syntax.
Docs:
- docs/Driver.AbCip.Cli.md — family ↔ CIP-path cheat sheet + examples per
command + typical workflows.
- docs/Driver.AbLegacy.Cli.md — PCCC address primer (file letters → CLI
--type) + known ab_server upstream gap cross-ref to #224 close-out.
Wiring:
- ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).
Full-solution build clean. `otopcua-abcip-cli --help` + `otopcua-ablegacy-cli
--help` verified end-to-end.
Next up (#251): S7 + TwinCAT CLIs, same pattern.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Mirrors the v1 otopcua-cli value prop (ad-hoc shell-level PLC validation) for
the Modbus-TCP driver, and lays down the shared scaffolding that AB CIP, AB
Legacy, S7, and TwinCAT CLIs will build on.
New projects:
- src/ZB.MOM.WW.OtOpcUa.Driver.Cli.Common/ — DriverCommandBase (verbose
flag + Serilog config) + SnapshotFormatter (single-tag + table +
write-result renders with invariant-culture value formatting + OPC UA
status-code shortnames + UTC-normalised timestamps).
- src/ZB.MOM.WW.OtOpcUa.Driver.Modbus.Cli/ — otopcua-modbus-cli executable.
Commands: probe, read, write, subscribe. ModbusCommandBase carries the
host/port/unit-id flags + builds ModbusDriverOptions with Probe.Enabled
=false (CLI runs are one-shot; driver-internal keep-alive would race).
Commands + coverage:
- probe single FC03 + GetHealth() + pretty-print
- read region × address × type synth into one driver tag
- write same shape + --value parsed per --type
- subscribe polled-subscription stream until Ctrl+C
Tests (38 total):
- 16 SnapshotFormatterTests covering: status-code shortnames, unknown
codes fall back to hex, null value + timestamp placeholders, bool
lowercase, float invariant culture, string quoting, write-result shape,
aligned table columns, mismatched-length rejection, UTC normalisation.
- 22 Modbus CLI tests:
· ReadCommandTests.SynthesiseTagName (5 theory cases)
· WriteCommandParseValueTests (17 cases: bool aliases, unknown rejected,
Int16 bounds, UInt16/Bcd16 type, Float32/64 invariant culture,
String passthrough, BitInRegister, Int32 MinValue, non-numeric reject)
Wiring:
- ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).
- docs/Driver.Modbus.Cli.md — operator-facing runbook with examples per
command + output format + typical workflows.
Regression: full-solution build clean; shared-lib tests 16/0, Modbus CLI tests
22/0.
Next up: repeat the pattern for AB CIP (shares ~40% more with Modbus via
libplctag), then AB Legacy, S7, TwinCAT. The shared base stays as-is unless
one of those exposes a gap the Modbus-first pass missed.

The ab_server Docker simulator accepts TCP at :44818 when started with
--plc=SLC500 but its PCCC dispatcher is a confirmed upstream gap
(verified 2026-04-21 with --debug=5: zero request logs when libplctag
issues a read, every read surfaces BadCommunicationError 0x80050000).
Previous behavior — when Docker was up, the three smoke tests ran and
all failed on every integration-host run. Noise, not signal.
New behavior — AbLegacyServerFixture gates on a new env var
AB_LEGACY_TRUST_WIRE:
Endpoint reachable? | TRUST_WIRE set? | Result
--------------------+-----------------+------------------------------
No | — | Skip ("not reachable")
Yes | No | Skip ("ab_server PCCC gap")
Yes | 1 / true | Run
The fixture's new skip reason explicitly names the upstream gap + the
resolution paths (upstream bug / RSEmulate golden-box / real hardware
via task #222 lab rig). Operators with a real SLC 5/05 / MicroLogix
1100/1400 / PLC-5 or an Emulate box set AB_LEGACY_ENDPOINT + TRUST_WIRE
and the smoke tests round-trip cleanly.
Updated docs:
- tests/.../Docker/README.md — new env-var table + three-case gate matrix
- Known limitations section refreshed to "confirmed upstream gap"
Verified locally:
- Docker down: 2 skipped.
- Docker up + TRUST_WIRE unset: 2 skipped (upstream-gap message).
- Docker up + TRUST_WIRE=1: 4 run, 4 fail BadCommunicationError (ab_server gap as expected).
- Unit suite: 96 passed / 0 failed (regression-clean).

Closes the scope-out left by the #242 partial. Root cause of the blazor.web.js
zero-byte response turned out to be two co-operating harness bugs:
1) The static-asset manifest was discoverable but the runtime needs
UseStaticWebAssets to be called so the StaticWebAssetsLoader composes a
PhysicalFileProvider per ContentRoot declared in
staticwebassets.development.json (Admin source wwwroot + obj/compressed +
the framework NuGet cache). Without that call MapStaticAssets resolves the
route but has no ContentRoot map — so every asset serves zero bytes.
2) The EF InMemory DB name was being re-generated on every DbContext
construction (the lambda body called Guid.NewGuid() inline), so the seed
scope, Blazor circuit scope, and test-assertion scopes all got separate
stores. Capturing the name as a stable string per fixture instance fixes
the "cluster not found → page stays at Loading…" symptom.
Fixes:
- AdminWebAppFactory:
* ApplicationName set on WebApplicationOptions so UseStaticWebAssets
discovers the manifest.
* builder.WebHost.UseStaticWebAssets() wired explicitly (matches what
`dotnet run` does via MSBuild targets).
* dbName captured once per fixture; the options lambda reads the
captured string instead of re-rolling a Guid.
- UnsTabDragDropE2ETests: the two [Fact(Skip=...)] tests un-skip.
Suite state: 3 passed, 0 skipped, 0 failed. Task #242 closed.

Carries the interactive drag-drop + 409 concurrent-edit test bodies (full Playwright
flows against the real @ondragstart/@ondragover/@ondrop handlers + modal + EF state
round-trip), plus several harness upgrades that push the in-process
WebApplication-based fixture closer to a working Blazor Server circuit. The
interactive tests are marked [Fact(Skip=...)] pending resolution of one remaining
blocker documented in the class docstring.
Harness upgrades (AdminWebAppFactory):
- Environment set to Development so 500s surface exception stacks (rather than
the generic error page) during future diagnosis.
- ContentRootPath pointed at the Admin assembly dir so wwwroot + manifest files
resolve.
- Wired SignalR hubs (/hubs/fleet, /hubs/alerts) so ClusterDetail's HubConnection
negotiation no longer 500s at first render.
- Services property exposed so tests can open scoped DI contexts against the
running host (scheduled peer-edit simulation, post-commit state assertion).
Remaining blocker (reason for Skip):
/_framework/blazor.web.js returns HTTP 200 with a zero-byte body. The asset's
route is declared in OtOpcUa.Admin.staticwebassets.endpoints.json, but the
underlying file is shipped by the framework NuGet package
(Microsoft.AspNetCore.App.Internal.Assets/_framework/blazor.web.js) rather than
copied into the Admin wwwroot. MapStaticAssets can't resolve it without wiring
a composite FileProvider or the WebRootPath machinery. Three viable next-session
approaches listed in the class docstring:
(a) Composite FileProvider mapping /_framework/* → NuGet cache.
(b) Subprocess harness spawning real dotnet run of Admin project with an
InMemory-DB override (closest to production composition).
(c) MSBuild ItemGroup in the test csproj that copies framework files into the
test output + ContentRoot=test assembly dir with UseStaticFiles.
Scaffolding smoke test (Admin_host_serves_HTTP_via_Playwright_scaffolding) stays
green unchanged.
Suite state: 1 passed, 2 skipped, 0 failed.

Closes the non-hardware gap surfaced in the #220 audit: FOCAS had full Tier-C
architecture (Driver.FOCAS + Driver.FOCAS.Host + Driver.FOCAS.Shared, supervisor,
post-mortem MMF, NSSM scripts, 239 tests) but no factory registration, so config-DB
DriverInstance rows of type "FOCAS" would fail at bootstrap with "unknown driver
type". Hardware-gated FwlibHostedBackend (real Fwlib32 P/Invoke inside the Host
process) stays deferred under #222 lab-rig.
Ships:
- FocasDriverFactoryExtensions.Register(registry) mirroring the Galaxy pattern.
JSON schema selects backend via "Backend" field:
"ipc" (default) — IpcFocasClientFactory → named-pipe FocasIpcClient →
Driver.FOCAS.Host process (Tier-C isolation)
"fwlib" — direct in-process FwlibFocasClientFactory (P/Invoke)
"unimplemented" — UnimplementedFocasClientFactory (fail-fast on use —
useful for staging DriverInstance rows pre-Host-deploy)
- Devices / Tags / Probe / Timeout / Series feed into FocasDriverOptions.
Series validated eagerly at top-level so typos fail at bootstrap, not first
read. Tag DataType + Series enum values surface clear errors listing valid
options.
- Program.cs adds FocasDriverFactoryExtensions.Register alongside Galaxy.
- Driver.FOCAS.csproj references Core (for DriverFactoryRegistry).
- Server.csproj adds Driver.FOCAS ProjectReference so the factory type is
reachable from Program.cs.
Tests: 13 new FocasDriverFactoryExtensionsTests covering: registry entry,
case-insensitive lookup, ipc backend with full config, ipc defaults, missing
PipeName/SharedSecret errors, fwlib backend short-path, unimplemented backend,
unknown-backend error, unknown-Series error, tag missing DataType, null/ws args,
duplicate-register throws.
Regression: 202 FOCAS + 13 FOCAS.Host + 24 FOCAS.Shared + 239 Server all pass.

PR #197 surfaced two integration-level wiring gaps in DriverNodeManager's
MarkAsAlarmCondition path; this commit fixes both and upgrades the integration
test to assert them end-to-end.
Fix 1 — addressable child nodes: AlarmConditionState inherits ~50 typed children
(Severity / Message / ActiveState / AckedState / EnabledState / …). The stack
was leaving them with Foundation-namespace NodeIds (type-declaration defaults) or
shared ns=0 counter allocations, so client Read on a child returned
BadNodeIdUnknown. Pass assignNodeIds=true to alarm.Create, then walk the condition
subtree and rewrite each descendant's NodeId symbolically as
{condition-full-ref}.{symbolic-path}
in the node manager's namespace. Stable, unique, and collision-free across
multiple alarm instances in the same driver.
Fix 2 — event propagation to Server.EventNotifier: OPC UA Part 9 event
propagation relies on the alarm condition being reachable from Objects/Server
via HasNotifier. Call CustomNodeManager2.AddRootNotifier(alarm) after registering
the condition so subscriptions placed on Server-object EventNotifier receive the
ReportEvent calls ConditionSink emits per-transition.
Test upgrades in AlarmSubscribeIntegrationTests:
- Driver_alarm_transition_updates_server_side_AlarmConditionState_node — now
asserts Severity == 700, Message text, and ActiveState.Id == true through
the OPC UA client (previously scoped out as BadNodeIdUnknown).
- New: Driver_alarm_event_flows_to_client_subscription_on_Server_EventNotifier
subscribes an OPC UA event monitor on ObjectIds.Server, fires a driver
transition, and waits for the AlarmConditionType event to be delivered,
asserting Message + Severity fields. Previously scoped out as "Part 9 event
propagation out of reach."
Regression checks: 239 server tests pass (+1 new event-subscription test),
195 Core tests pass.
