Closes Phase 7 Gap 5: VirtualTagEngine called IHistoryWriter.Record per evaluation
when Historize=true but Phase7EngineComposer always passed NullHistoryWriter, so
virtual-tag history was computed but never persisted.
The fix:
- New RingBufferHistoryWriter implements both IHistoryWriter (write port for the
evaluation pipeline) and IHistorianDataSource (read port for IHistoryRouter so
OPC UA HistoryRead on virtual-tag nodes resolves here). Maintains one bounded
ring buffer (1000 samples, configurable) per tag path; Record() is O(1) and
never blocks evaluation.
- Phase7EngineComposer.Compose now accepts IHistoryRouter? and, when any
VirtualTagDefinition.Historize=true, creates a RingBufferHistoryWriter, passes
it to VirtualTagEngine as historyWriter, adds it to the disposables list, and
registers it under the "virtual:" prefix in the router for HistoryRead dispatch.
- Phase7Composer accepts IHistoryRouter? from DI (already registered as singleton
in Program.cs) and threads it through to Phase7EngineComposer.Compose.
- NullHistoryWriter remains as fallback when no tags request historization.
- 16 new unit tests in RingBufferHistoryWriterTests.cs cover ring-buffer semantics,
eviction, per-tag isolation, ReadRawAsync windowing, IHistorianDataSource stubs,
router registration, and the Historize=false / null-router fallback paths.

Gap 1 of phase-7-status.md. Intercepts AcknowledgeableConditionType_Acknowledge and
AcknowledgeableConditionType_Confirm calls in DriverNodeManager.Call and dispatches
them to ScriptedAlarmEngine so OPC UA HMI clients can acknowledge/confirm scripted alarms
in addition to the existing Admin UI path. Shelve methods deferred (per-instance NodeIds,
not well-known type MethodIds — follow-up task). AlarmEngine is now exposed through
Phase7ComposedSources so the server wire-up passes it to every DriverNodeManager. 13 new
unit tests cover dispatch kernel, identity fallback, batch handling, and error paths.

Four DB-backed test fixtures still defaulted DefaultServer to
localhost,14330 — missed in the 2026-04-28 Docker migration that moved
SQL Server off this VM onto the shared host 10.100.0.35. With no SQL on
localhost, all 31 DB-backed tests failed with connection timeouts,
which in turn failed the Phase 6 compliance gate (phase-6-all.ps1).
Updated SchemaComplianceFixture, HostStatusPublisherTests,
FleetStatusPollerTests, and AdminServicesIntegrationTests to default to
10.100.0.35,14330 (still overridable via OTOPCUA_CONFIG_TEST_SERVER).
Verified: Configuration.Tests 91 pass, HostStatusPublisher 4 pass,
FleetStatusPoller + AdminServicesIntegration 5 pass — all 31 green.

Add DeferredGateHardeningTests (28 unit tests) covering the Phase 6.2
compliance-checklist gaps left by the per-gate unit suites that shipped
with the gate implementations:
- Lax-mode fall-through for CreateMonitoredItems and Call gates (null
identity and identity-without-LDAP-groups both skip denial in lax mode,
consistent with BrowseGatingTests.Lax_mode_null_identity)
- Flag isolation: Subscribe-only grant does NOT imply Read; Read-only
grant does NOT imply Subscribe; HistoryRead-only grant does NOT imply
Read and vice versa (Phase 6.2 compliance: "HistoryRead uses its own flag")
- Alarm-bit isolation: AlarmAcknowledge alone does not grant AlarmConfirm
or AlarmShelve; Browse alone does not grant AlarmAcknowledge
- AlarmShelve falls through to OpcUaOperation.Call in MapCallOperation
(documents the ShelvedStateMachine per-instance NodeId limitation noted
in the implementation, with the follow-up path: MethodCall grant covers it)
- Complete OpcUaOperation→NodePermissions mapping coverage for all deferred
operations (Browse, CreateMonitoredItems, TransferSubscriptions, Call,
AlarmAcknowledge, AlarmConfirm, AlarmShelve) — both positive and
wrong-bit negative cases
- Multi-group union for deferred gates (grp-browse ∪ grp-ack gives both
Browse and AlarmAcknowledge without leaking Read or Call)
Build: 0 errors on Server.csproj (verified against main repo build which
carries the gRPC-generated Galaxy driver artifacts the isolated worktree
lacks — that pre-existing gap is unrelated to these changes).
Test count: 247 → 275 (+28 unit, 0 failures).

ApplyReservationPreCheckAsync on EquipmentImportBatchService queries active
ExternalIdReservation rows in a single round-trip at parse time; rows whose ZTag
or SAPID is claimed by a different EquipmentUuid are moved from AcceptedRows to
RejectedRows with a descriptive reason. ImportEquipment.razor calls the check
after EquipmentCsvImporter.Parse so conflicts appear in the preview before the
operator clicks Stage + Finalise. Updated notice banner to reflect the pre-check

Add ResilientLdapGroupRoleMappingService — a singleton decorator that wraps the
hot-path GetByGroupsAsync call in a Polly pipeline (timeout 2s → retry 3× jittered
→ fallback to in-memory sealed snapshot) so a transient Config DB outage at
Admin sign-in falls back to the last-known-good mapping set rather than denying
every login. The static LdapOptions.GroupToRole bootstrap dictionary in
AdminRoleGrantResolver remains the lock-out-proof floor regardless of DB state.
DI wiring uses keyed services: LdapGroupRoleMappingService (EF, scoped) is
registered under key "LdapGroupRoleMappingService.Inner"; the resilient singleton
decorator is the primary ILdapGroupRoleMappingService binding. The singleton
avoids the captive-dependency anti-pattern by using IServiceScopeFactory to open
a short-lived scope for each DB call.
Write methods (CreateAsync, DeleteAsync, ListAllAsync) pass through unchanged —
resilience is read-path only per Phase 6.1 design decision.
15 new unit tests cover: DB success/failure/retry paths, snapshot sealing and
per-group-set isolation, order-independent cache key normalisation, cancellation
propagation, and pass-through method routing.

The role-grants page authored LdapGroupRoleMapping rows but nothing
consumed them — sign-in only read the static appsettings GroupToRole
dictionary. Wire the DB-backed grants into the auth path.
- AdminRoleGrantResolver merges the static bootstrap dictionary (always
fleet-wide, lock-out-proof) with DB grants; system-wide rows fold into
fleet roles, cluster-scoped rows become (cluster, role) grants.
- Login emits a ClaimTypes.Role claim per fleet role and a cluster_role
claim per cluster-scoped grant; lock-out check spans both scopes.
- ClusterRoleClaims + ClaimsPrincipal extensions resolve the effective
role for a cluster (highest of fleet-wide and cluster-scoped).
- ClusterAuthorizeView gates cluster pages: ClusterDetail (view +
ConfigEditor draft actions), DraftEditor (ConfigEditor / FleetAdmin
publish), DiffViewer (ConfigViewer), ImportEquipment (ConfigEditor).
- RoleGrants page is now FleetAdmin-only; Account surfaces fleet-wide
and cluster-scoped grants separately.
Control-plane only — decision #150 holds, NodeAcl is untouched.
Tests: AdminRoleGrantResolverTests + ClusterRoleClaimsTests (22).

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.

Fourteenth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR B.2 (GalaxyDriver
implements IAlarmSource, merged) and B.3 (DriverNodeManager prefers
driver-native ack, merged).
Three new optional fields on Core.Abstractions.AlarmEventArgs:
- OperatorComment — populated by the driver-native gateway path on
Acknowledge transitions. Null on raise / clear, and null on the
sub-attribute fallback path where the comment collapses into a
single string write.
- OriginalRaiseTimestampUtc — preserved across Acknowledge so OPC
UA Part 9 conditions keep the original raise time.
- AlarmCategory — taxonomy bucket from the upstream alarm system.
Maps to ConditionClassName downstream when a class mapping is
configured.
GalaxyDriver.OnPumpAlarmTransition populates the new fields from
GalaxyAlarmTransition (PR B.1). Empty strings collapse to null so
consumers can use is-null rather than is-null-or-empty checks.
Client.Shared mirror DTO (Client.Shared/Models/AlarmEventArgs)
gains the same three properties so the Client.UI / Client.CLI
surfaces can reflect the rich payload — the actual UI/CLI
verbose-output and Show-Details rendering ship as a follow-up
PR; this PR locks in the payload contract.
Tests:
- 2 new tests in Driver.Galaxy.Tests pin the populated-vs-null
behaviour for full-payload Acknowledge and bare-bones Raise
transitions respectively.
- Solution build clean.

Thirteenth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR B.2 (GalaxyDriver
implements IAlarmSource, merged).
When DriverNodeManager registers an AlarmConditionState with
AlarmConditionService, it now picks the acknowledger:
- Driver implements IAlarmSource → DriverAlarmSourceAcknowledger
routes the operator comment through IAlarmSource.AcknowledgeAsync
via the existing AlarmSurfaceInvoker (Phase 6.1 resilience pipeline,
no-retry per decision #143). Preserves operator-comment fidelity
end-to-end — the value-driven sub-attribute write collapses the
comment into a single string write that loses MxAccess metadata.
- Driver does not implement IAlarmSource →
DriverWritableAcknowledger fallback (existing behaviour for
AbCip / Modbus / S7 / etc).
The dedup logic that prefers driver-native transitions over
sub-attribute synthesis lives in AlarmConditionService and is
already in place — drivers that surface OnAlarmEvent (B.2) feed
the service directly, while sub-attribute writes still flow
through DriverNodeManager's ConditionSink so a Galaxy template
without $Alarm extensions stays functional.
Tests:
- 2 new routing-decision tests in
DriverAlarmSourceAcknowledgerRoutingTests pin the
IAlarmSource detection used at registration time.
- Server build clean.

Twelfth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR B.1 (EventPump
dispatch, merged) and PR E.2 (.NET SDK alarm methods, merged).
Restores the v1 IAlarmSource capability that PR 7.2 retired with the
legacy Galaxy.Host / Galaxy.Proxy projects.
GalaxyDriver gains:
- IAlarmSource on the class declaration → eight capabilities total
(IDriver / ITagDiscovery / IReadable / IWritable / ISubscribable /
IRediscoverable / IHostConnectivityProbe / IAlarmSource).
- SubscribeAlarmsAsync — returns a sentinel handle and starts the
shared EventPump (alarm wiring is lazy on first sub).
Multiple handles share the same gateway stream; the server-side
AlarmConditionService dispatches per-source-node downstream.
- UnsubscribeAlarmsAsync — symmetric handle removal; rejects
handles not issued by this driver.
- AcknowledgeAsync — issues one gateway RPC per acknowledgement
through IGalaxyAlarmAcknowledger. ConditionId carries the alarm
full reference; falls back to SourceNodeId when empty.
- OnAlarmEvent — bridges EventPump.OnAlarmTransition (B.1) onto
AlarmEventArgs. Suppressed when no alarm subscription is active so
untracked transitions don't leak through.
New runtime types:
- IGalaxyAlarmAcknowledger — test seam.
- GatewayGalaxyAlarmAcknowledger — production wrapper around
MxGatewayClient.AcknowledgeAlarmAsync (PR E.2). Maps native
MxStatus failures to a logged warning rather than a thrown
exception so a transient MxAccess hiccup doesn't fail the
operator's Acknowledge.
- GalaxyAlarmSubscriptionHandle — driver-side IAlarmSubscriptionHandle.
Production runtime construction in BuildProductionRuntimeAsync wires
the acknowledger when not pre-injected; tests inject a fake via the
internal ctor.
Tests:
- 7 new tests in GalaxyDriverAlarmSourceTests — subscribe → event
fire path, suppress without subscription, unsubscribe stops flow,
foreign-handle rejection, ack routes per-request, ack falls back
to SourceNodeId, ack throws NotSupported without acknowledger.
- Full Driver.Galaxy.Tests: 203 passed (was 196; 7 new).
Operates as a "stub-ready" surface — runtime ack calls will return
PERMISSION_DENIED until A.3 ships the gateway-side dispatch, and no
alarm transitions will arrive until A.2 adds the worker MxAccess
subscription. Both will activate this code path automatically when
the gateway side lands.

Sixth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR C.2 (sidecar
serves IAlarmEventWriter when enabled), already merged.
Today Phase7Composer.ResolveHistorianSink only scans drivers for an
IAlarmHistorianWriter — no Galaxy driver provides one since PR 7.2,
so the resolution falls through to NullAlarmHistorianSink and
scripted-alarm transitions are silently discarded.
WonderwareHistorianClient already implements IAlarmHistorianWriter
and Program.cs:178 already registers it as a singleton when
Historian:Wonderware:Enabled=true. The gap was that Phase7Composer
ignored DI: this PR adds an optional injectedWriter constructor
parameter, and ASP.NET Core DI resolves it from the same
registration when present.
- Phase7Composer constructor: new optional IAlarmHistorianWriter?
injectedWriter parameter (default null). Backward-compatible —
existing callers don't need to change; DI populates it
automatically when the singleton is registered.
- New static SelectAlarmHistorianWriter helper — resolution order
is driver → DI → null. Drivers win when both are present so a
future GalaxyDriver-as-IAlarmHistorianWriter takes the write
path directly, preserving the v1 invariant where a driver that
natively owns the historian client doesn't bounce through the
sidecar IPC.
- ResolveHistorianSink uses the helper + emits a structured log
line identifying which source provided the writer.
Tests:
- 4 SelectAlarmHistorianWriter precedence tests — no source / DI
only / driver wins over DI / first-driver-with-writer wins.
- Pre-existing 4 HostStatusPublisherTests SQL failures unrelated
to this change (require the docker-host SQL Server at
10.100.0.35,14330 per CLAUDE.md). Phase7 + alarm tests all
green.

Fifth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR C.1
(AahClientManagedAlarmEventWriter), already merged.
Today HistorianFrameHandler is constructed at Program.cs line 57
without an alarmWriter, so every WriteAlarmEvents frame replies
"Sidecar not configured with an alarm-event writer" and the lmxopcua
side keeps the row queued. C.2 wires a real writer behind a new
OTOPCUA_HISTORIAN_ALARM_WRITE_ENABLED toggle.
- Program.BuildAlarmWriter — gated on the env var (default true,
fail-open under accidental misconfiguration). Constructs an
AahClientManagedAlarmEventWriter wrapping a
SdkAlarmHistorianWriteBackend with the same connection config the
read path uses.
- Install-Services.ps1 — appends OTOPCUA_HISTORIAN_ALARM_WRITE_ENABLED=true
to the OtOpcUaWonderwareHistorian service env block when the
sidecar is installed. Read-only deployments flip it to false at
service-config edit time without re-installing.
- HistorianFrameHandler signature already accepts
IAlarmEventWriter? — supplying non-null at line 57 lights up
the WriteAlarmEvents reply path that's been dormant since PR 3.3.
Until PR D.1 pins the live aahClientManaged entry point, the
SdkAlarmHistorianWriteBackend reports RetryPlease for every event
with a structured diagnostic. The lmxopcua-side
SqliteStoreAndForwardSink retains queued events; same effective
behaviour as today's NullAlarmHistorianSink fallback but with
visible diagnostics rather than silent discard.
Tests:
- 6 BuildAlarmWriter env-var cases — unset / true / false /
unrecognized → default-on / capitalization variants.
- Full sidecar test suite: 56 passed (was 48; 8 new).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Fourth PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Independent of Tracks A and B —
the sidecar slot defined in HistorianFrameHandler line 242 is unwired
today; PR C.2 (next) flips it on in Program.cs.
- AlarmHistorianWriteOutcome (sidecar-local, net48 — twin of
Core.AlarmHistorian.HistorianWriteOutcome which is net10): Ack /
RetryPlease / PermanentFail.
- IAlarmHistorianWriteBackend abstraction so the SDK call can be
faked in unit tests.
- AahClientManagedAlarmEventWriter implements IAlarmEventWriter,
delegates to the backend, maps Ack→true / Retry|Permanent→false
for the IPC bool[] reply contract. Backend exception → whole
batch RetryPlease (preserves the sender's queue across transients
rather than dropping). Wrong-count return defends against a
backend bug desyncing queue accounting.
- SdkAlarmHistorianWriteBackend — production binding skeleton.
Reports RetryPlease for every event and logs a structured
diagnostic until PR D.1 pins the live aahClientManaged entry
point against the dev rig. The sender's SqliteStoreAndForwardSink
retains queued events, mirroring today's NullAlarmHistorianSink
behaviour but with visible diagnostics instead of silent discard.
- MapOutcome shared helper — pinned via theory tests so the D.1
swap can change the SDK call site without reshuffling the
HRESULT → outcome mapping.
Tests:
- 6 writer tests — empty batch / single Ack / mixed Ack-Retry-
Permanent-Ack ordering / backend-throw → RetryPlease batch /
cancellation propagates / wrong-count defensive degrade.
- 5 outcome theory cases — hresult 0 → Ack, malformed wins over
hresult 0, comm error → Retry, unknown failure → Retry,
malformed + comm → Permanent.
- Full sidecar test suite: 48 passed (was 42; 6 new).

Second PR of the alarms-over-gateway epic
(docs/plans/alarms-over-gateway.md). Depends on PR A.1 in mxaccessgw
(merged) which added the OnAlarmTransitionEvent body + family. No
runtime impact yet — the gateway doesn't emit the new family until
A.3 ships; this PR just stops dropping it on the floor.
EventPump.Dispatch becomes a switch on MxEventFamily. The new
DispatchAlarmTransition decodes the proto event, runs the raw severity
through MxAccessSeverityMapper (the same four-bucket ladder v1 used —
250/500/750/1000 boundaries per docs/v1/AlarmTracking.md), and fires
an internal OnAlarmTransition event with a GalaxyAlarmTransition
record carrying the full payload.
Body absent or transition-kind unspecified → counted via
galaxy.alarm_transitions.decoding_failures and dropped. Gateway
version skew or worker malformed event therefore degrades to "fall
back to the sub-attribute path" rather than crashing the pump.
GalaxyDriver consumes the internal event in PR B.2 (next), wrapping
it onto IAlarmSource.OnAlarmEvent. The richer fields (operator user
+ comment, original raise time, category) become visible on the OPC
UA Part 9 condition once AlarmEventArgs gets extended in E.7.
Tests:
- MxAccessSeverityMapperTests — full bucket ladder + clamp behaviour
for negative + out-of-range inputs.
- EventPumpAlarmTests — raise/ack/clear sequence dispatches in order
with operator metadata + original-raise preserved; unspecified
kind drops; missing body drops; mixed data-change + alarm streams
dispatch independently; OnWriteComplete / OperationComplete
filtered out.
Full Driver.Galaxy.Tests suite: 196 passed (was 191 — 5 new tests).

The sidecar was set to PlatformTarget=x86 + Prefer32Bit=true to mirror
v1's Driver.Galaxy.Host bitness, which itself was x86 only because of
MXAccess COM. PR 7.2 retired Galaxy.Host, so that constraint is gone.
AVEVA Historian 2020 ships an x64 build of every SDK assembly the
sidecar needs (lib\aahClientManaged.dll + aahClient.dll + aahClientCommon.dll
sourced from C:\Program Files (x86)\Wonderware\Historian\x64\; the
remaining three SDK assemblies — Historian.CBE / DPAPI /
ArchestrA.CloudHistorian.Contract — are pure-managed AnyCPU and load
in either bitness). Drop PlatformTarget to x64 on both the sidecar
project and its test project; running 37/37 historian tests + the
live install confirms the SDK loads and serves the named pipe in a
64-bit-native process.

End-to-end run on the live ZB galaxy with mxaccessgw on
http://localhost:5120: 14 passed / 1 skipped / 0 failed in 18m53s.
PR 7.2's matrix-gate condition met. Three resolution patches in this
commit; the matrix doc records the new state.
1. Discoverer: defensive `[]` array-suffix strip
----------------------------------------------------
The gw's GalaxyRepository.cs:173-175 appends `[]` to
array-typed full_tag_reference values, but MxAccess COM
IInstance.AddItem doesn't accept `[]`-suffixed addresses.
GalaxyDiscoverer.StripArraySuffix removes the suffix client-side
so SubscribeBulk / Read / Write paths see the canonical form.
Tracked in mxaccessgw/requirements-array-suffix-fix.md; this
workaround is removed when the gw fix lands.
2. WriteByClassification: pin status class, not exact code
---------------------------------------------------------
Legacy MxAccessGalaxyBackend.WriteValuesAsync flat-maps every
failure to BadInternalError (0x80020000); mxgw's
GatewayGalaxyDataWriter.TranslateReply uses
MxStatusProxy.RawDetectedBy to distinguish gw-layer faults
(BadCommunicationError, 0x80050000) from MxAccess HRESULT
faults. Both yield Bad-status — the parity invariant is the
status class (Good/Uncertain/Bad), not the exact code. Both
write tests now use AssertStatusClassMatches; legacy mapping
retires alongside GalaxyProxyDriver in PR 7.2.
3. BrowseAndReadParity Read scenario: drop CLR-type assertion
------------------------------------------------------------
Legacy returns the raw VARIANT (e.g. byte[]) for an attribute
that hasn't received its first value cycle from MxAccess yet,
while mxgw returns the typed value (Single, Int32, etc.). Once
a real value is written or scanned, both converge. Pinning
CLR-type equality across the uninitialized window adds noise
without a real parity invariant — the StatusCode-class
assertion already covers the "did the read succeed" question.
The test still pins StatusCode-class parity per scenario.
4. Galaxy.ParityMatrix.md — first-rig results captured
-----------------------------------------------------
Per-row status flipped from "n/a unverified" to actual
green / yellow / deferred outcomes from this run. Four new
accepted-deltas added (read-value CLR type, write-status code
mapping, single-platform ScanState scope, gw `[]` suffix
workaround), bringing the total to nine. Outstanding deltas
section flipped to "none as of 2026-04-30."
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
After running the matrix end-to-end against the live rig for the
first time, three of the nine failures were false positives — bugs in
the harness and test invariants, not real backend deltas:
1. ParityHarness configured the legacy backend with
OTOPCUA_GALAXY_BACKEND=db, which is Discover-only. Reads, writes,
and reinits all returned "MXAccess code lift pending — DB-backed
backend covers Discover only". Switched to mxaccess backend; the
ZB connection string still drives the discovery path.
2. HistoryReadParityTests asserted "neither backend implements
IHistoryProvider" — but the legacy GalaxyProxyDriver still does
(it's an accepted back-compat delta retired in PR 7.2). The
architectural pin we *want* is "the new path doesn't regress to
per-driver history", so the test now asserts only the mxgw side.
3. AlarmTransitionParityTests strict-pinned the five sub-attribute
refs (InAlarmRef, etc.) on the legacy condition. PR 2.1 added
those refs specifically so the new mxgw driver could populate them
via AlarmRefBuilder; legacy pre-dates PR 2.1 and leaves them null
— that's correct, not a regression. Test now asserts a one-way
invariant: when legacy populated a ref, mxgw must match. When
legacy is null, mxgw is free to populate (the mxgw → server-side
AlarmConditionService direction).
The six remaining failures are real:
- 2 from the gw-side `[]` array suffix (filed in
mxaccessgw/requirements-array-suffix-fix.md)
- 2 write-StatusCode mapping deltas (0x80050000 vs 0x80020000) —
Bad-status both ways but mapped to different OPC UA codes
- 1 event-rate ratio of 5x (mxgw dispatches 5x legacy in the same
3s window)
- (Plus the 2 ScanState scenarios that skip cleanly — single-platform
rig as documented)

Lands the five concrete code-level follow-ups identified after Phase 7.1:
#1 GalaxyDriver.ReadAsync now works in production. Previously threw
NotSupportedException when no test reader was injected. New path
subscribes through the existing SubscriptionRegistry + EventPump,
waits for the first OnDataChange per item handle (gw pushes the
initial value after SubscribeBulk), then unsubscribes. Tags the gw
rejects up front, or that don't publish before the caller's CT
fires, return Bad-status snapshots in input order so callers still
get one snapshot per requested reference.
#2 ResolveApiKey() routes Gateway.ApiKeySecretRef through three forms:
env:NAME, file:PATH, or literal-string fallback. A future DPAPI arm
slots in here without touching the call site.
#3 GatewayGalaxySubscriber actually honors bufferedUpdateIntervalMs now
(was being silently dropped). Calls SetBufferedUpdateInterval via
the gw's MxCommandKind.SetBufferedUpdateInterval before SubscribeBulk
when the requested interval differs from the cached last-applied
value. Soft-fails on a non-Ok protocol status (the SubscribeBulk
still succeeds at gw cadence).
#4 GalaxyMxAccessOptions.EventPumpChannelCapacity surfaces the bounded-
channel size through DriverConfig JSON, defaulting to 50_000.
#5 Stale doc-comments in HostStatusAggregator and GatewayGalaxySubscriber
describing follow-ups that already shipped.
Tests: +6 (read subscribe-once happy path + rejected-tag fallback;
five resolver scenarios). Total Galaxy driver tests now 180/180 green.

Long-running soak harness exercising the in-process GalaxyDriver
against a live mxaccessgw. Subscribes a configurable tag count
(default 50_000), holds the subscription for a configurable duration
(default 24h), polls the EventPump's three counters every minute, and
asserts:
- events.received continues to grow (gw stream isn't stuck)
- events.dropped stays under a configurable percent ceiling
(default 0.5%)
- process working-set doesn't grow >1 GB above baseline (leak guard)
Always skipped unless the operator opts in via OTOPCUA_SOAK_RUN=1.
Tag count, duration, and drop ceiling are env-overridable
(OTOPCUA_SOAK_TAGS / OTOPCUA_SOAK_MINUTES / OTOPCUA_SOAK_DROP_PCT) so
a smoke run can compress the scenario for CI gating.
Per-minute progress is logged as a CSV-style line to stdout so an
operator can grep the test runner output mid-run. PR 6.5 consumes the
data this scenario emits to tune MxGatewayClientOptions defaults.

Wires MxAccess.PublishingIntervalMs into the gw's SubscribeBulk
bufferedUpdateIntervalMs parameter on both subscribe paths:
- GalaxyDriver.SubscribeAsync — when the caller passes TimeSpan.Zero
(typical for infrastructure callers like the deploy watcher), the
driver substitutes _options.MxAccess.PublishingIntervalMs. When the
caller sets a non-zero interval (the server's UA subscription
publishingInterval), that wins.
- PerPlatformProbeWatcher — new bufferedUpdateIntervalMs ctor parameter
defaulting to 0 (gw default cadence). GalaxyDriver passes
_options.MxAccess.PublishingIntervalMs so probe ScanState changes
publish at the configured rate.
Tests: caller-wins-when-non-zero, fallback-to-config-when-zero on the
driver; default-zero, configured-forwarded, negative-rejected on the
probe watcher.
A session-level SetBufferedUpdateInterval RPC exists in the gw protocol
(MxCommandKind.SetBufferedUpdateInterval) but the .NET client doesn't
expose a typed helper yet — adjusting an existing subscription's
interval is a follow-up. Today's path subscribes once with the right
interval, which covers the common case.

Decouples the gw stream-read loop from the listener-fanout loop with a
bounded Channel<MxEvent> (default capacity 50_000) sitting between them.
When a slow listener fills the channel, the producer's TryWrite returns
false and we count the drop rather than back-pressuring the gw stream.
Three counters on the ZB.MOM.WW.OtOpcUa.Driver.Galaxy meter expose the
pressure curve before it manifests as user-visible loss:
- galaxy.events.received — MxEvents read from StreamEvents
- galaxy.events.dispatched — MxEvents that made it through to OnDataChange
- galaxy.events.dropped — MxEvents discarded because the channel was full
Each measurement carries a galaxy.client tag so multi-driver hosts can
split by source. The driver wires _options.MxAccess.ClientName into the
new EventPump constructor parameter.
Tests: drop-newest under pressure, capacity validation, and per-pump
measurement filtering (xUnit can run other pump tests in parallel and
their measurements land on the same listener — the test filters to its
own client name).

In-box ActivitySource ("ZB.MOM.WW.OtOpcUa.Driver.Galaxy") wrapped around
the three gw-facing seams via decorators:
- TracedGalaxySubscriber — galaxy.subscribe_bulk / galaxy.unsubscribe_bulk
/ galaxy.stream_events spans. Stream span covers the entire stream
lifetime with a galaxy.event_count tag (per-event spans would dominate
the trace volume at 50k tags / 1Hz; PR 6.2 owns per-event metrics).
- TracedGalaxyDataWriter — galaxy.write spans tagged with
galaxy.tag_count, galaxy.secured_write_count (split between FreeAccess
/Operate vs Tune/Configure/VerifiedWrite, computed only when a listener
is recording so the hot path stays free), galaxy.success_count.
- TracedGalaxyHierarchySource — galaxy.get_hierarchy spans tagged with
galaxy.object_count.
GalaxyDriver.BuildProductionRuntimeAsync wraps the production seams in
the decorators. The driver itself doesn't take an OpenTelemetry package
dependency — System.Diagnostics.ActivitySource is in-box; the host
process picks the listener.

Closes Phase 5 scenario coverage. Both
GalaxyRuntimeProbeManager (legacy) and PerPlatformProbeWatcher (PR 4.7)
must surface the same per-host status stream:
- GetHostStatuses_emits_same_host_set_after_Discover — drives Discover
on both backends, waits 1.5s for the probe watcher's first push, then
asserts the platform-host set agrees (transport-entry names differ
by design — legacy uses the Galaxy.Host process identity, mxgw uses
MxAccess.ClientName, so we strip those before comparing).
- GetHostStatuses_state_per_platform_matches_across_backends — for
every overlapping platform host, the HostState must be identical.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Reinitialize_returns_both_backends_to_Healthy — drives
ReinitializeAsync on each backend, asserts DriverState.Healthy
afterwards, then re-reads a 3-tag sample to confirm the runtime
surface is back. Recovery latency isn't pinned tightly (legacy = pipe
+ MxAccess COM client, mxgw = re-Register gw session — different
cadences are expected).
- Health_state_diverges_only_when_one_backend_is_in_recovery — soft
pin that both backends sit in Healthy or Degraded after init.
A tighter fault-injection scenario (toxiproxy-style) is the 5.7
follow-up — landed when the parity rig grows that capability.

Galaxy history reads route through the server-owned HistoryRouter
(Phase 1, PR 1.3) — neither Galaxy backend implements IHistoryProvider
directly. Parity surface here is the routing decision:
- Discover_emits_same_historized_attribute_set_for_both_backends — the
IsHistorized attribute set must agree symmetric-set-wise; that's what
HistoryRouter consumes when deciding whether to route a HistoryRead to
the Wonderware historian sidecar.
- Neither_Galaxy_backend_implements_IHistoryProvider_directly — pins
the architectural decision so a regression that re-introduces a
per-driver history path fires.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Discover_emits_same_AlarmConditionInfo_per_alarm_attribute — both
backends produce the same alarm-condition source-node-id set, with
matching SourceName / InitialSeverity / InAlarmRef / DescAttrNameRef
per condition. Skips when the rig's Galaxy carries no alarm-marked
attributes.
- Discover_marks_at_least_one_alarm_attribute_when_dev_Galaxy_has_alarms
— IsAlarm-marked variable count parity, soft-pinned (count must
match across backends but doesn't have to be non-zero).
Alarm-event persistence (the SQLite store-and-forward → Wonderware
historian event store path) is exercised in PR 5.6 against the
historian sidecar.

Both backends route a write through the same path keyed off the attribute's
SecurityClassification, so a single write request must produce the same
StatusCode on each:
- FreeAccess_or_Operate_write_returns_same_StatusCode_on_both_backends
picks the first numeric FreeAccess/Operate attribute and writes 0.0.
- Configure_class_write_routes_through_secured_path_on_both_backends
picks a Configure/Tune attribute, writes through the secured path,
asserts StatusCode parity (the test doesn't care whether the write
succeeds — only that both backends produce the same outcome).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Subscribe_returns_a_handle_for_each_backend — both backends accept
the same full-reference list and return a non-null handle, with
symmetric Unsubscribe cleanup.
- Subscribe_event_rate_within_tolerance_for_a_3s_window — counts
OnDataChange invocations on each backend across a 3s window and
asserts the mxgw/legacy ratio sits in [0.5, 1.5]. Skips when the
sampled tags don't change in the window (configuration-only Galaxy).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three scenarios using ParityHarness.RequireBoth:
- Discover_emits_same_variable_set_for_both_backends — symmetric set diff
on the full-reference set must be empty.
- Discover_emits_same_DataType_and_SecurityClass_per_attribute — meta
triple (DriverDataType, SecurityClass, IsHistorized) must match per
attribute.
- Read_returns_same_value_and_status_for_a_sampled_attribute — samples
the first 5 discovered variables, reads through both backends, asserts
StatusCode equality and value-CLR-type equality (raw values may drift
between the two reads on a live Galaxy).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Side-by-side fixture that boots both backends against the same dev Galaxy:
- Legacy GalaxyProxyDriver against an out-of-process Galaxy.Host EXE
(skipped when ZB SQL on localhost:1433 isn't reachable or when the EXE
hasn't been built).
- New in-process GalaxyDriver against an mxaccessgw gateway at
http://localhost:5120 by default (skipped when the gateway isn't
reachable). Endpoint, API key, and client name are env-var overridable
for the central parity host.
Per-backend availability is independent — each scenario decides whether
to RequireBoth, GetDriver(specific), or use RunOnAvailableAsync to drive
both with the same closure and diff snapshots. PR 5.2–5.8 land scenarios
on top of this shell.

- GalaxyDriver.InitializeAsync now builds the production gw runtime (MxGatewayClient,
GalaxyMxSession, GatewayGalaxySubscriber, GatewayGalaxyDataWriter,
ReconnectSupervisor, HostConnectivityForwarder, PerPlatformProbeWatcher) when no
test seams are pre-injected; Dispose tears the chain down in order.
- GetHealth surfaces supervisor.IsDegraded as DriverState.Degraded so a transport
drop is observable without polling the supervisor directly.
- DiscoverAsync now refreshes the per-platform probe watcher's membership against
$WinPlatform / $AppEngine objects after every discovery pass.
- OnPumpDataChange routes ScanState changes through the probe watcher in addition
to fanning out OnDataChange to ISubscribable consumers.
- Server registers GalaxyDriver under "GalaxyMxGateway" alongside the legacy
"Galaxy" GalaxyProxyDriver factory so DriverInstance rows can opt in.
- Bumped Server.Tests' Microsoft.Extensions.Logging.Abstractions to 10.0.7 to
resolve the downgrade pulled in transitively via MxGateway.Client.
- Lifecycle factory tests switched to the internal seam-injection ctor so they
no longer attempt a real gRPC connect during InitializeAsync.

HostStatusAggregator merges transport + per-platform host entries with
change-event diffing (re-asserting same state is a no-op so a stable
ScanState=Running burst doesn't fan out duplicates). PerPlatformProbeWatcher
ports the legacy GalaxyRuntimeProbeManager state machine onto the gw
subscription path: SubscribeBulk for `<tag>.ScanState`, idempotent
SyncPlatformsAsync (subscribe new, unsubscribe dropped), and a
DecodeState helper pinning bool/int/string ScanState values + bad-quality
fallback. HostConnectivityForwarder is the skeleton for the gw-6
StreamSessionHealth signal — until that mxaccessgw RPC ships, PR 4.5's
ReconnectSupervisor pushes transport state by calling SetTransport on
session connect/disconnect.
GalaxyDriver wiring (implement IHostConnectivityProbe, route OnDataChange
to PerPlatformProbeWatcher, expose GetHostStatuses() / OnHostStatusChanged,
push transport from supervisor) is deferred to PR 4.W to avoid conflict
with the rest of the Phase 4 deferred wiring (4.5 supervisor + 4.6
DeployWatcher).
Tests: 19 new
- HostStatusAggregatorTests (9): empty snapshot, new-host change with
Unknown predecessor, same-state silence, transition diff, snapshot
reflects every host, case-insensitive host names, Remove returns true
for tracked, Remove false for unknown, concurrent updates don't corrupt.
- HostConnectivityForwarderTests (5): SetTransport routes under client
name, transitions fire change, repeated same-state silent, empty client
name throws, post-dispose throws.
- PerPlatformProbeWatcherTests (5 + theory pinning DecodeState's full
truth table): subscribe N platforms, idempotent re-sync, removed
platforms unsubscribed + dropped from aggregator, OnProbeValueChanged
routing for Running/Stopped/bad-quality/foreign-ref, Dispose
unsubscribes everything.
NOTE: build is currently broken because mxaccessgw/clients/dotnet/ has
been removed from C:\Users\dohertj2\Desktop\mxaccessgw — this PR's source
is internally consistent and isolated from the missing dependency, but the
existing Driver.Galaxy code (PRs 4.1–4.6) can't compile until the .NET
client is restored. Once it is, expect 116 + 19 = 135 tests in the
Driver.Galaxy.Tests project.

State machine that drives GalaxyDriver's recovery from gw transport
failure. Healthy → TransportLost → Reopening → Replaying → Healthy. Drivers
report failure signals; the supervisor runs reopen + replay with capped
exponential backoff (default 500ms → 30s) until both succeed.
Files:
- Runtime/ReconnectSupervisor.cs — state machine with snapshot, change
event, last-error tracking, and a one-attempt-at-a-time recovery loop.
Idempotent ReportTransportFailure: repeated failure reports during an
in-flight recovery do not spawn parallel loops. Reopen + replay are
caller-supplied callbacks (the driver injects them in the wire-up PR);
reopen re-Registers the gw session, replay re-establishes every active
subscription via gw's ReplaySubscriptionsCommand (mxaccessgw issue gw-3)
or the SubscribeBulk fallback. Dispose cancels the loop cleanly.
- Public StateTransition record + IsDegraded predicate the driver maps
to DriverState.Degraded for health snapshots.
Wiring (GalaxyDriver subscribes the supervisor to its EventPump's
transport-failure signal, exposes IsDegraded through GetHealth(), routes
reopen/replay callbacks through GalaxyMxSession + SubscriptionRegistry)
lands in PR 4.W to avoid conflict with the parallel host-probe track
(PR 4.7) and align the wire-up with the rest of Phase 4's plumbing.
9 supervisor tests (full state-machine traversal, retry-until-success on
both reopen and replay failures, idempotent failure reports, last-error
propagation, Dispose mid-recovery, post-dispose throws, fast-path Healthy
WaitForHealthy).

DeployWatcher consumes GalaxyRepositoryClient.WatchDeployEventsAsync,
suppresses the bootstrap event, and raises RediscoveryEventArgs whenever
time_of_last_deploy actually changes. Reconnect-on-error with capped
exponential backoff. GalaxyDriver wiring (IRediscoverable.OnRediscoveryNeeded
event + StartAsync inside InitializeAsync) lands in a follow-up so this PR
doesn't conflict with the parallel runtime track.

Subscription path online. GalaxyDriver implements ISubscribable; subscribes
batches via gw SubscribeBulkAsync, runs a single shared EventPump consumer
of StreamEventsAsync, fans out OnDataChange events to every driver
subscription that observes the changed gw item handle.
Files:
- Runtime/GalaxySubscriptionHandle.cs — record implementing ISubscriptionHandle.
- Runtime/SubscriptionRegistry.cs — bookkeeping with forward (subscriptionId
→ bindings) and reverse (itemHandle → list of subscriptionIds) maps. The
reverse map is the fan-out index so a single OnDataChange dispatches to
every subscription that observes the changed handle.
- Runtime/IGalaxySubscriber.cs — driver-side seam: SubscribeBulk +
UnsubscribeBulk + StreamEventsAsync. Production wraps GalaxyMxSession;
tests substitute a fake driving synthetic MxEvents.
- Runtime/GatewayGalaxySubscriber.cs — production. Forwards to
MxGatewaySession; bufferedUpdateIntervalMs is captured for now and
becomes a SetBufferedUpdateInterval call once gw issue #102 / gw-9 lands
(PR 6.3 picks this up).
- Runtime/EventPump.cs — long-running background consumer of
StreamEventsAsync. Decodes MxValue + maps quality byte/MxStatusProxy via
StatusCodeMap. Fan-out per subscriber resolves through the registry; bad
handler exceptions are caught + logged, never break the dispatch loop.
Filters out non-OnDataChange families (write-complete and operation-
complete come back via InvokeAsync's reply path, not the event stream).
GalaxyDriver:
- Adds ISubscribable. SubscribeAsync allocates a subscription id,
SubscribeBulks, builds the binding list (failed gw entries get
ItemHandle=0 + a per-tag warn log), registers, and returns the handle.
EventPump is started lazily on first subscribe; one pump per driver
shared across all subscriptions.
- UnsubscribeAsync removes from the registry first (so stale events are
filtered immediately) then calls UnsubscribeBulk best-effort. Foreign
handles throw ArgumentException.
- ReadAsync NotSupportedException message updated: PR 4.4 no longer the
pointer (deferred to a small follow-up that wraps the pump as a
one-shot reader).
- Dispose tears down the pump first, then the repository client, then
clears state.
- Internal ctor extended with optional subscriber parameter.
Tests (15 new, 109 Galaxy total):
- SubscriptionRegistryTests: monotonic id allocation, single+multi
subscription fan-out, failed-handle exclusion, removal isolation, count
invariants.
- GalaxyDriverSubscribeTests: handle allocation + value-change dispatch,
multi-subscription fan-out, failed-tag silence, unsubscribe drops gw
handle and stops dispatch, foreign handle throws, no-subscriber throws,
empty-tag-list returns handle without calling gw.

Write path online. GalaxyDriver implements IWritable; routes by
SecurityClassification — SecuredWrite / VerifiedWrite tags go through
MxCommandKind.WriteSecured, everything else through MxGatewaySession.
WriteAsync. Per-tag classifications are captured during ITagDiscovery via a
SecurityCapturingBuilder wrapper that intercepts Variable() calls without
the discoverer needing to know about the driver's internal state.
Files:
- Runtime/MxValueEncoder.cs — boxed CLR value → MxValue. Covers seven Galaxy
scalar types (bool/int8-32/uint8-32 → Int32, int64/uint64 → Int64, float,
double, string, DateTime/DateTimeOffset → Timestamp) and 1-D array
variants. Inverse of MxValueDecoder; round-trip pinned by tests.
DateTime.Local converts to UTC; unsupported types throw ArgumentException.
- Runtime/IGalaxyDataWriter.cs — driver-side seam. Tests inject a fake to
capture routing decisions; production path uses GatewayGalaxyDataWriter.
- Runtime/GatewayGalaxyDataWriter.cs — production. Lazy-AddItem caches
itemHandles, encodes value, routes Write vs WriteSecured, translates
MxCommandReply (ProtocolStatus → BadCommunicationError; first
MxStatusProxy in statuses[] via StatusCodeMap.FromMxStatus). Per-tag
exception isolation: one bad write doesn't fail the batch.
- GalaxyDriver: now implements IWritable. Discovery wraps the supplied
IAddressSpaceBuilder in SecurityCapturingBuilder which records each
attribute's SecurityClass into _securityByFullRef before delegating.
WriteAsync resolves classification per tag (FreeAccess default for
unknown tags — matches the legacy backend), routes through the injected
writer. Throws NotSupportedException with PR 4.4 pointer when no writer
is wired (production path requires GalaxyMxSession.Connect from PR 4.4).
Tests (32 new, 94 Galaxy total):
- MxValueEncoder: every scalar type, narrowing checks (sbyte/short/byte/
ushort fit Int32; uint within Int32 range; ulong within Int64),
DateTime.Local → UTC conversion, array variants for bool/double/string/
DateTime, Dimensions populated, unsupported-type throws ArgumentException,
encoder/decoder round-trip pin.
- GalaxyDriverWriteTests: WriteAsync routes through fake writer with
values intact; theory exercises every SecurityClassification value through
the discovery-then-write path; unknown-tag defaults to FreeAccess; empty-
request short-circuit; no-writer fail-loud; post-dispose throws.

Read path scaffold + the byte→uint quality mapping table that the parity
matrix (PR 5.x) pins. PR 4.4 supplies the production GW-backed reader; this
PR ships the abstraction and the supporting infrastructure so 4.4 just
plugs the implementation in.
Files:
- Runtime/StatusCodeMap.cs — explicit OPC DA quality byte → OPC UA
StatusCode uint mapping. Extends the legacy Galaxy.Host
HistorianQualityMapper with named constants (Good / GoodLocalOverride,
Uncertain + 4 substatuses, Bad + 7 substatuses, BadInternalError) and an
MxStatusProxy → uint helper that honors success flag → detail byte →
detected_by transport-error fallback. Unknown bytes fall back to category
bucket with a once-per-session diagnostic log so field captures can
extend the table.
- Runtime/MxValueDecoder.cs — gateway MxValue → boxed CLR value for the
seven Galaxy data types (Boolean, Int32, Int64, Float32, Float64, String,
DateTime) plus their array variants. Honors MxValue.IsNull and
RawValue passthrough.
- Runtime/IGalaxyDataReader.cs — driver-side seam for one-shot reads. PR
4.4 ships the production wrapper around MxGatewaySession.SubscribeBulk +
StreamEvents + UnsubscribeBulk; this PR exposes the contract so
GalaxyDriver.ReadAsync wires through it.
- Runtime/GalaxyMxSession.cs — wrapper around MxGatewaySession that owns
the Register handle. ConnectAsync opens session + Register; AttachForTests
lets tests bypass real gw construction. PR 4.3/4.4/4.5 add write,
subscribe, and reconnect surfaces.
GalaxyDriver:
- Implements IReadable. ReadAsync routes through the injected
IGalaxyDataReader (test seam) when present; production path throws
NotSupportedException pointing at PR 4.4 — protects deployments running
this PR from silent wrong reads while signaling that the legacy-host
backend (Galaxy:Backend=legacy-host) handles reads in the meantime.
- Internal ctor extended with optional dataReader parameter (default null,
preserves PR 4.0/4.1 callers).
Tests: 42 new — exhaustive byte→uint table for StatusCodeMap (15 known
codes + category-bucket fallback for unknowns + MxStatusProxy precedence
rules + OPC UA top-byte invariants), every MxValue oneof case for the
decoder (bool/int32/int64/float/double/string/timestamp/3 array variants/
raw bytes/null), GalaxyDriver IReadable wiring (route-through, empty-
request, no-reader-throws, post-dispose-throws, status-code preservation).
62 Galaxy tests total pass.

Browse path online. GalaxyDriver now implements ITagDiscovery against the
gateway's GalaxyRepositoryClient (PR 0.1's mxaccessgw browse RPC) and feeds
the address-space builder one folder per gobject + one variable per dynamic
attribute, with alarm-bearing attributes carrying all five sub-attribute refs
the server-level AlarmConditionService (PR 2.2) needs.
Files:
- Browse/IGalaxyHierarchySource.cs — driver-side seam between the discoverer
and the gateway. Test fakes return canned hierarchies so the discoverer's
translation logic is exercised without a real gRPC channel.
- Browse/GatewayGalaxyHierarchySource.cs — production wrapper around
GalaxyRepositoryClient.DiscoverHierarchyAsync (paged internally).
- Browse/GalaxyDiscoverer.cs — translates GalaxyObject → IAddressSpaceBuilder
calls. Browse name = contained_name (falls back to tag_name); full
reference = attr.full_tag_reference when set, else tag_name + "." +
attribute_name. Skips objects/attributes with empty identity.
- Browse/DataTypeMap.cs — mx_data_type → DriverDataType (port from legacy
GalaxyProxyDriver.MapDataType, same fallback to String for unknown codes).
- Browse/SecurityMap.cs — security_classification → SecurityClassification
(port from legacy GalaxyProxyDriver.MapSecurity).
- Browse/AlarmRefBuilder.cs — populates the five sub-attribute refs by
Galaxy convention (.InAlarm/.Priority/.DescAttrName/.Acked/.AckMsg). The
same convention the legacy GalaxyAlarmTracker hard-coded; concentrated
here so PR 2.2's service receives complete AlarmConditionInfo rows.
GalaxyDriver:
- Added internal ctor accepting IGalaxyHierarchySource? for test injection.
Default lazily builds GatewayGalaxyHierarchySource around a
GalaxyRepositoryClient constructed from options on first DiscoverAsync.
- Owned GalaxyRepositoryClient disposed in Dispose.
- ApiKey resolution is currently a passthrough of ApiKeySecretRef — PR 4.W
(or follow-up) wires DPAPI-backed secret resolution.
csproj: path-based ProjectReference to mxaccessgw (the user is shipping
that repo on a parallel track; both repos sit side-by-side on the dev box).
Tests project also references MxGateway.Contracts directly to construct
GalaxyObject / GalaxyAttribute fixtures.
Tests: 10 new in Browse/GalaxyDiscovererTests.cs covering folder-per-object,
variable-per-attribute, full-ref defaulting + gw-supplied override, browse-
name fallback, every metadata field propagation, alarm sub-attribute ref
population, non-alarm rows skip MarkAsAlarmCondition, empty-identity skips,
empty-attribute-name skips, end-to-end through GalaxyDriver.DiscoverAsync.
20 total Galaxy tests pass.

New in-process .NET 10 driver project at
src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy/. The Tier-A replacement for
Driver.Galaxy.Host + Driver.Galaxy.Proxy. PR 4.0 ships only the IDriver
shape + factory + options; capability bodies (browse, read, write,
subscribe, deploy-watch, host probes) land in PRs 4.1–4.7.
Files:
- Driver.Galaxy.csproj — net10 x64, AnyCPU+x64 platforms, references
Core.Abstractions + Core. No MxGatewayClient ProjectReference yet — that
comes in PR 4.2 once the gw NuGet package is wired (the user is
shipping mxaccessgw on a parallel track).
- Config/GalaxyDriverOptions.cs — nested record hierarchy
(Gateway/MxAccess/Repository/Reconnect) mirroring the JSON shape spelled
out in lmx_mxgw_impl.md PR 4.0 acceptance section.
- GalaxyDriver.cs — minimal IDriver impl. Initialize/Shutdown toggle
DriverHealth between Healthy/Unknown; Reinitialize bumps the timestamp;
GetMemoryFootprint=0 (PR 4.4 wires SubscriptionRegistry size);
FlushOptionalCachesAsync no-op. Logs intent on lifecycle calls so
partial deployments are diagnosable.
- GalaxyDriverFactoryExtensions.cs — JSON parser, default fill-ins,
validation throw on missing required fields. Driver type name
"GalaxyMxGateway" intentionally distinct from legacy "Galaxy" so both
factories coexist during parity testing (Phase 5). PR 4.W's
Galaxy:Backend switch picks one or the other.
Tests:
- 10 tests in Driver.Galaxy.Tests covering minimal-config defaults, full
override path, three required-field error cases, factory registration
via DriverFactoryRegistry.TryGet, lifecycle health transitions
(Init → Shutdown → Reinit), Dispose idempotency, and post-disposal
ObjectDisposedException.
slnx: registers the new Driver.Galaxy + Driver.Galaxy.Tests projects.

New project Driver.Historian.Wonderware.Client (net10 x64) implements both
Core.Abstractions.IHistorianDataSource (read paths consumed by the server's
IHistoryRouter) and Core.AlarmHistorian.IAlarmHistorianWriter (alarm-event
drain consumed by SqliteStoreAndForwardSink) against the sidecar's PR 3.3
pipe protocol.
Wire-format files (Framing/MessageKind, Hello, Contracts, FrameReader,
FrameWriter) are byte-identical mirrors of the sidecar's net48 originals —
the sidecar can't be referenced as a ProjectReference because of the
runtime/bitness gap, so we duplicate and pin the wire bytes via tests.
PipeChannel owns one bidirectional NamedPipeClientStream + Hello handshake +
serializes calls. Single in-flight at a time (semaphore); transport failures
trigger one in-flight reconnect-and-retry before propagating. Connect is
abstracted behind a Func<CancellationToken, Task<Stream>> so tests inject
in-process pipes.
WonderwareHistorianClient maps:
- HistorianSampleDto.Quality (raw OPC DA byte) → OPC UA StatusCode uint via
QualityMapper (port of HistorianQualityMapper from sidecar).
- HistorianAggregateSampleDto.Value=null → BadNoData (0x800E0000).
- WriteAlarmEventsReply.PerEventOk[i]=true → Ack, false → RetryPlease.
Whole-call failure or transport exception → RetryPlease for every event in
the batch (drain worker handles backoff).
- AlarmHistorianEvent → AlarmHistorianEventDto with severity bucketed via
AlarmSeverity-to-ushort mapping (Low=250, Medium=500, High=700, Crit=900).
GetHealthSnapshot tracks transport success + sidecar-reported failure
separately; ConsecutiveFailures rises on operation-level errors, not just
transport drops.
10 round-trip tests via FakeSidecarServer (in-process net10 fake using the
client's own framing): byte→uint quality mapping, null-bucket BadNoData,
at-time order preservation, event-field round-trip, sidecar error surfacing,
WriteBatch per-event status, whole-call retry-please mapping, Hello
shared-secret rejection, transport-drop reconnect-and-retry, health snapshot
counters.
PR 3.W will register this client as IHistorianDataSource + IAlarmHistorianWriter
in OpcUaServerService DI.

cap. Hello handshake validates per-process shared secret + protocol major
version + caller SID via ImpersonateNamedPipeClient before any work frame
runs.
Five contract pairs ship in this PR:
ReadRawRequest ↔ ReadRawReply
ReadProcessedRequest ↔ ReadProcessedReply
ReadAtTimeRequest ↔ ReadAtTimeReply
ReadEventsRequest ↔ ReadEventsReply
WriteAlarmEventsRequest ↔ WriteAlarmEventsReply
Timestamps cross the wire as DateTime ticks (long) to dodge MessagePack's
DateTime kind/timezone quirks; both sides convert with DateTime(ticks, Utc).
Sample values cross as MessagePack-serialized byte[] so the .NET 10 client
(PR 3.4) deserializes per the tag's mx_data_type without the sidecar needing
to know OPC UA types.
HistorianFrameHandler dispatches by MessageKind to IHistorianDataSource (the
PR 3.2 lifted interface) for reads, and to a new IAlarmEventWriter strategy
for the alarm-event persistence path. Per-call exceptions surface as
Success=false replies so a single bad request doesn't kill the connection.
WriteAlarmEvents replies carry per-event success flags; the SQLite
store-and-forward sink retries failed slots on the next drain tick.
Program.cs spins the pipe server when OTOPCUA_HISTORIAN_ENABLED=true. Pipe-
only mode (default false) preserves PR 3.1's smoke-test behaviour: the host
still validates env vars and waits for Ctrl-C, but doesn't initialize the
Wonderware SDK.
Sidecar test project gains 8 round-trip tests (37 total now): every contract
pair round-trips through FrameReader/FrameWriter via in-memory streams, the
handler surfaces historian exceptions cleanly, WriteAlarmEvents per-event
status flows through, and the no-writer-configured path returns a clean
error reply.
Added MessagePack 2.5.187 to the sidecar csproj.

Move all historian implementation files from Driver.Galaxy.Host/Backend/Historian/
to Driver.Historian.Wonderware/Backend/. Sidecar now owns the aahClientManaged /
aahClientCommon SDK references; Galaxy.Host project-references the sidecar so
MxAccessGalaxyBackend keeps building until PR 7.2 retires Galaxy.Host entirely.
10 source files moved (preserving git history via git mv):
IHistorianDataSource, HistorianDataSource, HistorianClusterEndpointPicker,
HistorianClusterNodeState, HistorianConfiguration, HistorianEventDto,
HistorianHealthSnapshot, HistorianQualityMapper, HistorianSample,
IHistorianConnectionFactory.
2 historian tests moved alongside (HistorianClusterEndpointPickerTests,
HistorianQualityMapperTests). Sidecar test project now hosts 29 tests (1 PR 3.1
smoke + 28 moved historian tests, all passing).
Galaxy.Host's remaining 6 historian-flavored tests (HistorianWiringTests,
HistoryReadAtTimeTests, HistoryReadEventsTests, HistoryReadProcessedTests)
keep passing via the project reference — using directives updated to reach
the new namespace.
Sidecar deliberately speaks no Core.Abstractions — its surface is the legacy
List<HistorianSample> shape; PR 3.4's .NET 10 client translates to the
Core.Abstractions shapes added in PR 1.1.

#155 wired the basic tag form (Name / Driver / Equipment / DataType / Access /
WriteIdempotent + ModbusAddressEditor for the address). The per-tag knobs added
across #141 / #142 / #143 still required operators to hand-edit TagConfig JSON.
This commit exposes them through an "Advanced" expander.
UI changes (TagsTab.razor):
- Collapsible "▶ Advanced (Deadband / UnitId override / CoalesceProhibited)"
button below the address editor, visible only when the selected driver is
Modbus. Collapsed by default — basic form covers the typical edit workflow.
- Three numeric / checkbox inputs with inline help text explaining each knob's
purpose and when to use it.
- _showAdvanced auto-opens on Edit when any of the advanced fields are present
in the existing TagConfig — operators see immediately what's been configured.
Save-side serialization:
- New RefreshTagConfigJson serializes the address + advanced fields into a
structured JSON object using a Dictionary<string, object?>. Fields with
default / empty values are omitted to keep diffs in the existing draft-diff
viewer minimal — a tag with only an address still produces
`{"addressString":"40001:F"}` and not a full superset object with nulls.
- OnAddressChanged + OnAdvancedChanged both delegate to RefreshTagConfigJson
so any input change keeps TagConfig in sync.
Read-side hydration:
- New HydrateModbusFromTagConfig parses an existing TagConfig JSON and
populates _modbusAddress + the three advanced fields. Falls back to empty
defaults on malformed JSON. ResetAdvanced is called before hydration on
every form open so leftover state from a previous edit doesn't leak.
ResetAdvanced helper introduced + called from StartAdd so a fresh "New tag"
form starts with everything cleared.
Tests (1 new in TagServiceTests):
- TagConfig_With_Advanced_Modbus_Fields_RoundTrips_Through_Factory — creates a
tag whose TagConfig carries addressString + deadband + unitId +
coalesceProhibited, persists via TagService, reloads, asserts every field
survives. Then constructs a wrapping driver-config JSON and feeds it to
ModbusDriverFactoryExtensions.CreateInstance — confirms the field NAMES the
UI emits match what BuildTag's DTO consumes. If the UI's JSON shape ever
drifts from the factory's expected DTO, this test catches it before users do.
119 + 1 = 120 Admin tests green. Solution build clean.
Closes the remaining loop on user-visible Modbus tag editing. Pre-#155 tags
arrived only via SQL seeding or runtime ITagDiscovery; the Admin UI had no
interactive surface for creating / editing / deleting tag rows.
Changes:
- TagService.cs (Admin/Services/) — CRUD wrapper around OtOpcUaConfigDbContext.Tags.
ListAsync supports optional driver / equipment filters; CreateAsync auto-derives
TagId; UpdateAsync persists editable fields; DeleteAsync removes the row. Mirrors
the EquipmentService shape.
- TagsTab.razor (Components/Pages/Clusters/) — list + filter + add/edit/remove form.
The address/config editor is conditional: when the selected DriverInstance is
Modbus, ModbusAddressEditor (#145) renders with live-parse preview; otherwise a
generic JSON textarea (matches the DriversTab pattern from #147). Save-side
serializes the address-string into TagConfig as `{"addressString":"..."}` JSON.
- ClusterDetail.razor — new "Tags" tab in the cluster-detail nav strip + the routing
switch.
- Program.cs — TagService registered as a scoped DI service.
Drive-by fix: ModbusDriverFactoryExtensions.CreateInstance promoted from internal
to public — Admin.Tests was using it via reflection-friendly internal access that
broke under the #153 logger overload addition. Public is the right access modifier
anyway since the Server-side bootstrapper calls it from a different assembly.
Drive-by fix#2: ModbusDriverConfigDto was missing MaxReadGap (#143) — surfaced by
the #147 round-trip test that flips MaxReadGap=12 in the view model and asserts
it lands on the resolved options. Added the field + binding line. Confirms #143's
DriverConfig JSON binding was incomplete since the original commit; no production
deployment configured this knob through JSON until now so the gap stayed hidden.
Tests (4 new TagServiceTests):
- Create_And_List_Surfaces_The_Tag — CreateAsync auto-assigns TagId; list returns
the row.
- List_Filters_By_DriverInstance — driver-scoped filter works.
- Update_Persists_Editable_Fields — Name / DataType / AccessLevel / TagConfig all
persist through Update.
- Delete_Removes_The_Row — basic delete verification.
113 + 4 (TagService) + 2 (DriversTab round-trip restored after compile fix) = 119
Admin tests green. Solution build clean.
Caveat: bUnit-style render tests for TagsTab still aren't included — Admin.Tests
doesn't have bUnit set up. The TagService logic is fully covered; the razor
component's parser/save glue is exercised by hand at runtime for now.
Foundation for surfacing per-driver runtime state from the Server process to
the Admin UI. #152 shipped GetAutoProhibitedRanges() as an in-process
accessor; #154 makes it reachable across processes.
Server side (HealthEndpointsHost):
- New URL family: /diagnostics/drivers/{driverInstanceId}/{driverType}/{topic}
- First wired topic: /diagnostics/drivers/{id}/modbus/auto-prohibited
- Driver-agnostic at the URL level — future driver types add their own
segments[3] cases (e.g. /diagnostics/drivers/{id}/s7/dropped-pdus).
- 404 when the driver instance doesn't exist; 400 when the driver exists
but isn't a Modbus driver (the per-type endpoint is wrong for this row).
- Response shape is flat JSON (unitId / region / startAddress / endAddress /
lastProbedUtc / bisectionPending) so consumers don't have to reference the
Driver.Modbus assembly's ModbusAutoProhibition record.
- Re-uses the existing HttpListener bound to localhost:4841 — same auth /
reachability story as /healthz and /readyz.
Admin side:
- DriverDiagnosticsClient (Services/) — HttpClient wrapper that fetches the
per-driver Modbus prohibition list. Returns null on 404/400 (driver
missing or wrong type); throws on transport failures.
- ModbusAutoProhibitionsResponse + ModbusAutoProhibitionRow flat DTOs —
client doesn't take a dep on Driver.Modbus.
- ModbusDiagnostics.razor at /modbus/diagnostics/{driverInstanceId} —
table view with BISECTING (warning yellow) / ISOLATED (danger red)
badges, relative timestamps (e.g. "5m ago"), Refresh button. Errors
surface inline rather than swallowing.
- HttpClient registration in Program.cs reads
DriverDiagnostics:ServerBaseUrl from appsettings.json (default
http://localhost:4841/ for same-host deployments).
Tests (3 new in HealthEndpointsHostTests):
- Diagnostics_ReturnsModbusAutoProhibitions_ForLiveDriver — registers a
Modbus driver with a programmable transport that protects register 102,
records the prohibition via a coalesced ReadAsync, hits the endpoint,
asserts the returned JSON matches (unitId / region / start / end / pending).
- Diagnostics_404_When_Driver_Not_Found
- Diagnostics_400_When_Driver_Is_Wrong_Type
Architecture note: the Admin-side bUnit-style component test isn't included
because Admin.Tests doesn't have bUnit set up. The DriverDiagnosticsClient
is unit-testable on its own with a mock HandlerStub if needed — left as a
follow-up alongside the broader bUnit setup task.
The diagnostic page is now reachable at /modbus/diagnostics/{driverId} from
any Admin instance pointing at a Server endpoint URL. Future driver types
(S7, AbCip) plug into the same channel by adding their own URL segments
in HealthEndpointsHost.WriteDriverDiagnosticsAsync.
