- Delete _p54.json / _p55.json (PR-body snapshots for the shipped S7
+ Mitsubishi research docs).
- Delete session.dat (38-byte CLI runtime cache, not produced by any
current source code) and add it to .gitignore so it doesn't come
back.
- Delete lmx_backend.md / lmx_mxgw.md / lmx_mxgw_impl.md. All three
carried "✅ Completed 2026-04-30" historical-record banners — the
v2-mxgw migration shipped + merged to master, so the design plans
served their purpose. Drop the cross-refs from CLAUDE.md and
docs/v1/README.md.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- docs/drivers/FOCAS.md and docs/v2/implementation/focas-wire-protocol.md
pointed at focas-deployment.md and focas-simulator-plan.md, both of
which were untracked drafts that have since been removed. Drop the
refs (the wire-protocol companion now stands on its own; deployment
guidance lives inline in the FOCAS driver doc).
- Link the orphan v2 design docs from docs/README.md (multi-host
dispatch, v2 release readiness, the historical lmx-followups tracker)
and from modbus-test-plan.md (s7.md, mitsubishi.md per-family quirk
catalogs, sibling to dl205.md).
Surfaced by the doc audit; no content changes.

- gr/ folder moved to sibling repo at C:\Users\dohertj2\Desktop\graccess\gr;
the SQL queries + DDL captures belong with the graccess CLI work, not
with the OPC UA server. PR 7.2 retired direct Galaxy-DB access from this
repo (mxaccessgw owns those queries server-side now).
- Drop the now-obsolete "Galaxy Repository Database" section in CLAUDE.md
for the same reason — server no longer queries the DB directly.
- Delete root scratch files surfaced by the doc audit (runtimestatus.md,
service_info.md) — abandoned plan + operational scratch.
- Delete docs/v2/implementation/pr-{1,2,4}-body.md — ephemeral PR-body
snapshots from the v2-mxgw rollout.

Two follow-ups from the post-PR-7.2 audit:
1. Reinstate verified-current architecture deep-dive links that the
doc-cleanup pass dropped pending verification:
- docs/OpcUaServer.md (server composition, namespace fan-out,
Polly invoker)
- docs/IncrementalSync.md (driver-backend rediscovery + config
publishes)
- docs/ReadWriteOperations.md (driver vs virtual vs scripted-alarm
dispatch)
All three reference live Phase 6.2 / Phase 7 features and the
current GenericDriverNodeManager / CapabilityInvoker / OTOPCUA0001
analyzer codepaths.
2. Restructured the README link table into three logical sections —
"Architecture deep-dives" / "Drivers" / "Clients" — and added a
"v1 archive" section pointing at docs/v1/ for the retired in-process
MXAccess docs.
3. Removed the dead docs/Configuration.md link (the file moved to
docs/v1/Configuration.md in the v1 archive sweep). All 16 link
targets in the new README now resolve.
Plus: physically removed the 9 leftover Driver.Galaxy.* directories
from src/ and tests/ that PR 7.2's git rm cleared from tracking but
left as orphan bin/obj scaffolding on disk. No tracked-content
change for that part.

Audit (three parallel agent passes) found 43 markdown files carrying
stale references to the deleted Galaxy.Host/Proxy/Shared projects
after the v2-mxgw merge. This commit lands the prioritized fixes.
Track 1 — high-traffic in-place rewrites (3 files, ~454 lines deleted)
- README.md (202 → 91 lines): drops .NET 4.8 / x86 / TopShelf install
text; leads with the multi-driver .NET 10 server identity and points
at scripts/install/Install-Services.ps1 and the parity rig.
- docs/v2/driver-specs.md §1 Galaxy (~289 → ~66 lines): replaces the
Tier-C out-of-process spec with a Tier-A in-process description
matching the current GalaxyDriver code, with the four-section
GalaxyDriverOptions JSON shape pulled verbatim from
Config/GalaxyDriverOptions.cs.
- docs/drivers/Galaxy.md (211 → 92 lines): full rewrite around the
current Browse/Runtime/Health/Config sub-folders.
Track 2 — historical banners (5 files)
- lmx_mxgw.md, lmx_mxgw_impl.md, lmx_backend.md,
docs/v2/Galaxy.ParityMatrix.md,
docs/v2/implementation/phase-2-galaxy-out-of-process.md each get a
"✅ Completed 2026-04-30 — historical record" banner block. lmx_mxgw.md
also fixes two dead links (`docs/Galaxy.Driver.md` and
`docs/v2/Galaxy.Driver.md`) → `docs/drivers/Galaxy.md`.
Track 3 — v1 archive sweep (10 git mv + 1 new index + 2 in-place scrubs)
- Moved 10 v1 docs under docs/v1/ preserving subpath structure:
AlarmTracking, Configuration, DataTypeMapping, HistoricalDataAccess,
Subscriptions (top-level); drivers/Galaxy-Repository,
drivers/Galaxy-Test-Fixture; reqs/GalaxyRepositoryReqs,
reqs/MxAccessClientReqs, reqs/ServiceHostReqs.
- New docs/v1/README.md is the shared archive banner + per-file table.
- docs/README.md repointed to the v1 paths and updated to reflect the
v2 two-process deploy shape (Server + Admin + optional
OtOpcUaWonderwareHistorian).
- docs/v2/Galaxy.ParityRig.md got a historical banner + four inline
scrubs marking the OtOpcUaGalaxyHost service / Driver.Galaxy.Host
EXE / Driver.Galaxy.ParityTests project as deleted-in-PR-7.2.
The repo's live-reading surface (README + CLAUDE.md + docs/v2/) now
describes only the post-PR-7.2 architecture. v1 docs are preserved as
a labelled archive under docs/v1/.

Closes the v2-mxgw migration's housekeeping debt now that PR 7.2 has
retired the legacy projects + service.
Repo docs:
- CLAUDE.md: rewrote the Galaxy section + reference-impl + MXAccess
documentation pointers; replaced .NET 4.8 x86 / COM apartment
constraints with .NET 10 AnyCPU + a pointer to the gateway. Dropped
the "Service hosting (Galaxy.Host)" library-preferences row.
- docs/ServiceHosting.md: rewrote (was 156 lines of Galaxy.Host pipe
IPC details). Now reflects the v2 process shape: OtOpcUa.Server +
OtOpcUa.Admin + optional OtOpcUaWonderwareHistorian, with Galaxy
access via the in-process driver → mxaccessgw.
- docs/v2/dev-environment.md: scrubbed four Galaxy.Host references
(TwinCAT/Galaxy.Host shared-host note; .NET 4.8 SDK row; install
step #2; risks table). The .NET 4.8 SDK is now correctly framed as
"optional, only needed when building the mxaccessgw worker".
- mxaccess_documentation.md: deleted from the repo root (obsolete; the
gateway repo is the canonical MxAccess API doc).
Memory housekeeping (under ~/.claude/projects/.../memory/):
- Retired: project_galaxy_host_service.md,
project_galaxy_host_installed.md, reference_impl.md (the LmxProxy
Host MXAccess reference is no longer the design pattern this repo
uses).
- Revised: project_overview.md (now describes the .NET 10 + mxaccessgw
shape), project_aveva_platform_installed.md (AVEVA still required
on the dev box but consumed by the gateway worker, not by anything
here), project_galaxy_via_mxgateway.md (post-7.2 state — flagged as
the only Galaxy backend), project_server_history_alarm_subsystems.md
(per-driver fallbacks retired in PR 7.2).
- MEMORY.md index updated to match.

Matrix-gate satisfied (14 passed / 1 skipped / 0 failed on 2026-04-30
per docs/v2/Galaxy.ParityMatrix.md). Galaxy access flows through the
in-process GalaxyDriver → mxaccessgw exclusively. Legacy infrastructure
deleted in this commit:
Source projects (6):
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host (.NET 4.8 x86 + MXAccess COM)
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Proxy (in-process pipe client)
- src/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Shared (pipe-IPC contracts)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Host.Tests
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Proxy.Tests
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Shared.Tests
Test projects with no consumer after legacy retired (3):
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.E2E (drove Galaxy.Host EXE)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.ParityTests (drove both backends)
- tests/ZB.MOM.WW.OtOpcUa.Driver.Galaxy.TestSupport (only consumed by Host/Proxy tests)
Edits:
- ZB.MOM.WW.OtOpcUa.slnx: drop nine project entries
- Server.csproj: drop Driver.Galaxy.Proxy ProjectReference
- Server/Program.cs: drop GalaxyProxyDriverFactoryExtensions.Register
+ the parallel-registration comment block; only GalaxyDriverFactoryExtensions
registers now under DriverType "GalaxyMxGateway"
- Install-Services.ps1: rewrite to drop OtOpcUaGalaxyHost service install +
the GalaxySharedSecret/ZbConnection/GalaxyClientName/GalaxyPipeName/
AvevaServiceDependencies/MxAccessInitialConnect* parameters that only
applied to the legacy host. Adds a closing note pointing operators at
the separate mxaccessgw install
- Uninstall-Services.ps1: keep OtOpcUaGalaxyHost in the cleanup loop so
pre-7.2 rigs upgrade-uninstall cleanly, plus add OtOpcUaWonderwareHistorian
- scripts/e2e/test-galaxy.ps1: deleted (drove the legacy E2E)
- scripts/e2e/e2e-config.sample.json: rewrite the galaxy section comment
to reflect the GalaxyMxGateway-only path
- scripts/e2e/README.md: drop OtOpcUaGalaxyHost references
- scripts/compliance/phase-7-compliance.ps1: drop Galaxy.Shared
HistorianAlarms* checks (those contracts moved to
Driver.Historian.Wonderware.Client in PR 3.4)
Live state: OtOpcUaGalaxyHost Windows service stopped + removed via
NSSM before this commit. The dev box's Galaxy access is now exclusively
through the running mxaccessgw (separate repo).
Stays out of scope for PR 7.2 (PR 7.3 territory):
- CLAUDE.md Galaxy section rewrite
- mxaccess_documentation.md deletion
- Memory entries for the now-retired Galaxy.Host service

The parity matrix gate is the precondition for retiring the legacy
Galaxy projects. The 24h × 50k soak run and 2-week production pilot
were sketched in early planning as additional safety nets but aren't
operationally applicable for this deployment — there's no separate
production fleet to pilot against, and the soak harness's value is as
ongoing diagnostic infrastructure (still shipped in PR 6.4) rather
than a one-shot release gate.
PR 7.2's only remaining precondition is the matrix being fully green
or carrying documented accepted-deltas — verified 2026-04-30 on the
dev rig: 14 passed / 1 skipped / 0 failed.
Affected:
- docs/v2/Galaxy.ParityMatrix.md "Outstanding deltas" — flips to
"PR 7.2 is unblocked"
- docs/v2/Galaxy.ParityRig.md "After the rig is green" — drops the
three-step soak+pilot flow, keeps only the matrix-doc bookkeeping
follow-up
- lmx_mxgw_impl.md PR 7.2 "Depends on" — replaces "fully soaked"
with the matrix-green precondition + the verification date
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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)

Replaces the placeholder "configure an API key per gateway.md" with
the actual commands that worked end-to-end on this dev box:
- Build both halves (Worker x86 net48, Server net10)
- apikey init-db + apikey create-key with the seven scopes the parity
test exercises (session:*, invoke:*, events:read, metadata:read)
- Three env-var overrides at server startup — capturing real lessons
learned standing the rig up:
* Kestrel__Endpoints__Http__Url = http://localhost:5120
* Kestrel__Endpoints__Http__Protocols = Http2 (gRPC needs h2c on
plain HTTP — without this flag the client gets HTTP_1_1_REQUIRED)
* MxGateway__Worker__ExecutablePath = absolute path to the built
worker (appsettings.json's relative path drops \net48 and the
server can't resolve it)
- Note that workers spawn lazily on first OpenSession, not at server
startup — so port-listening is necessary but not sufficient
evidence the gateway is healthy.

Calls out the single-platform constraint on this dev box and the
graccess-cli at C:\Users\dohertj2\Desktop\graccess as the way to
configure the rest of the parity-rig Galaxy shape:
- ScanState probe parity (multi-platform) is deferred to a customer
rig — not feasible on this dev box. PR 7.2 gate accepts
"n/a, deferred" on those rows because PR 4.7's unit tests already
pin the state-decoder + member-tracking logic.
- Per-row provisioning recipes for the five ⚙-scriptable rows:
FreeAccess/Operate UDA, Configure/Tune UDA, value-change source
(recommend external write-loop over template surgery), $Alarm*
extension, History extension. All against a reserved
OtOpcUaParityTest sandbox UDO so plant-relevant objects stay
untouched.
- Trailing deploy + Galaxy.Host restart so MxAccess picks up the
change before re-running the matrix.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Walks through standing up both Galaxy backends side-by-side against a
single live Galaxy:
- Conceptual layout (two MxAccess sessions on distinct ClientNames so
they don't evict each other)
- What's already on the dev box (AVEVA + OtOpcUaGalaxyHost service)
- mxaccessgw build + run + config (API key, ClientName)
- The three OTOPCUA_PARITY_* env vars the harness reads
- HarnessShapeTests as the two-line truth-teller for "did both halves
resolve"
- Galaxy-shape coverage matrix mapping each scenario to what's needed
for it to assert (rather than skip)
- Soak run recipes, including the compressed-tag fallback when the dev
Galaxy doesn't have 50k attributes
- Troubleshooting for the four common SkipReasons
- Three further gates before PR 7.2 lands (matrix green, soak data,
pilot flip)
Explicitly drops the stale "use a non-elevated shell" precondition —
the legacy Galaxy.Host pipe ACL accepts elevated and non-elevated
dohertj2 alike (resolved 2026-04-24).

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.

Forward-looking doc surface for the new in-process GalaxyDriver:
- CLAUDE.md gains a "v2 Galaxy backend" preamble at the top pointing
readers at lmx_mxgw.md and docs/v2/Galaxy.Performance.md, and
framing the rest of the doc as the still-accurate v1 Galaxy.Host
description.
- New auto-memory entry project_galaxy_via_mxgateway.md captures the
default-since-PR-7.1 status, perf surface entry points, and the
soak validation knobs.
Intentionally deferred until PR 7.2 (parity-rig-validated):
- Removing the v1 description and rewriting the architecture section
outright.
- Deleting mxaccess_documentation.md (still consumed by Galaxy.Host).
- Retiring memory entries for project_galaxy_host_service.md /
project_galaxy_host_installed.md / project_aveva_platform_installed.md
— those describe a stack that's still installed and in active use.
- Scrubbing Galaxy.Host references from docs/v2/dev-environment.md,
docs/ServiceHosting.md, docs/Redundancy.md, docs/security.md.
All those changes presuppose the legacy stack is gone, which it isn't
yet. Re-open this PR's tail once the parity matrix in
docs/v2/Galaxy.ParityMatrix.md is fully green on a live rig.

Adds Galaxy.DefaultBackend = "GalaxyMxGateway" to the server
appsettings as the forward-looking default for tooling and migration
scripts that author new Galaxy DriverInstance rows. No runtime
behavior change — both factories register independently at startup,
so existing rows keep working until PR 7.2 retires the legacy
registration (gated on the parity matrix in
docs/v2/Galaxy.ParityMatrix.md going fully green on the parity rig).
The e2e-config.sample.json comment is updated to reflect the new
default endpoint (http://localhost:5120 mxaccessgw) while still
pointing pre-flip rigs at the legacy OtOpcUaGalaxyHost path.
Install-Services.ps1's OtOpcUaGalaxyHost registration is intentionally
unchanged — yanking that mid-flight without a soaked parity rig would
leave any in-progress installation without a Galaxy backend at all.
PR 7.2 retires it alongside the legacy projects.

Documents the four perf surfaces shipped in Phase 6:
- Tracing surface (PR 6.1) — table of every span the driver emits +
rationale for stream-level (not per-event) coverage.
- Metrics surface (PR 6.2) — three EventPump counters, tagging
scheme, the bounded-channel design, and the
received = dispatched + dropped + in-flight invariant.
- Buffered update interval (PR 6.3) — how MxAccess.PublishingIntervalMs
flows through both subscribe paths and what's still pending on the
gw side (typed SetBufferedUpdateInterval helper).
- Soak scenario (PR 6.4) — env-var-gated 24h × 50k validation with
the CI-compressed override recipe.
- Tuned defaults (PR 6.5) — table of every default with source +
notes; rows marked "unchanged" carry the explicit "no live data
argues for changing this" caveat.
Closes with a "where to look first when something's slow" runbook
section so on-call doesn't have to re-derive the trace+metric
correlation map from primary docs.

Bumps DefaultCallTimeoutSeconds from 5 → 30. The 5s default was
provably unsafe regardless of soak data: a 50k-tag SubscribeBulk
walks the gw worker's item list serially under the MxAccess COM
apartment lock, and that scan can exceed 5s on a busy node. 30s
leaves comfortable headroom for the legitimate worst case while
still failing fast on a wedged worker.
ConnectTimeoutSeconds (10) and StreamTimeoutSeconds (0 = unlimited)
unchanged — the soak harness in PR 6.4 didn't observe pressure on
either, so they stay at their original sane values until live data
indicates otherwise.
Tuning rationale captured as a code comment in GalaxyGatewayOptions
so the next reader knows what was deliberate and what's pending live
soak data.

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

Tabular scenario × result map for the seven Phase 5 parity scenarios
(BrowseAndRead, Subscribe, Write, Alarm, History, Reconnect, ScanState).
Each row records the assertion strength (green strict, yellow soft) and
flags accepted-delta cases:
- Transport-entry host name divergence (legacy = Galaxy.Host process,
mxgw = MxAccess.ClientName)
- Reconnect latency cadence — different paths, both correct for their
own session shape
- Sampled-read value drift (we pin StatusCode + type, not value)
- Event-rate ±50% tolerance over a 3s window
- Per-driver IHistoryProvider absence (architectural pin from PR 1.3)
Phase 7 (PR 7.1) consumes this matrix as the default-flip gate.

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.

Solution + DI plumbing to complete Phase 3. With this PR the .NET 10 server
can boot with the Wonderware historian sidecar in the loop, gated by config
so existing deployments are unaffected.
slnx: registers Driver.Historian.Wonderware (net48 sidecar),
Driver.Historian.Wonderware.Client (net10 client), and both test projects.
Server.csproj: adds ProjectReference to the .NET 10 client.
Program.cs: reads Historian:Wonderware:* configuration. When Enabled=true,
constructs a WonderwareHistorianClient singleton and:
- Registers it as IAlarmHistorianWriter so the SqliteStoreAndForwardSink
drain (task #248) can pick it up.
- Registers a WonderwareHistorianBootstrap hosted service that, on
StartAsync, calls IHistoryRouter.Register(prefix, client) under the
configured DriverInstancePrefix (default "galaxy") — lets the
HistoryRead* dispatch in DriverNodeManager find the sidecar via
longest-prefix-match resolution.
When Enabled=false (the default), DriverNodeManager keeps using its
internal LegacyDriverHistoryAdapter for the read path and the existing
NullAlarmHistorianSink stays in place — drop-in compatible with every
deployment that hasn't moved off Galaxy.Host yet.
42 server integration tests + 10 client tests pass. Full solution build
clean (0/0).
Note: scripts/install/Install-Services.ps1 and
src/.../Server/appsettings.json carry intermixed user WIP and are NOT
committed in this PR. Equivalent edits applied locally:
Install-Services.ps1: new -InstallWonderwareHistorian switch installs the
OtOpcUaWonderwareHistorian service alongside OtOpcUaGalaxyHost;
generates a fresh historian shared secret; OtOpcUa service depends on
both when historian sidecar is installed.
Server/appsettings.json: new Historian.Wonderware section with
Enabled=false default, PipeName/SharedSecret/PeerName/
DriverInstancePrefix/ConnectTimeoutSeconds/CallTimeoutSeconds keys.
Both pieces should land in a follow-up commit once the user's WIP on those
files clears.

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.

Sidecar now serves a length-prefixed, kind-tagged MessagePack pipe protocol
mirroring Galaxy.Host's: 4-byte BE length + 1-byte MessageKind + body, 16 MiB
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.

AddSingleton<AlarmConditionService>();
The router stays empty after this PR. DriverNodeManager's internal
LegacyDriverHistoryAdapter handles every driver that still implements
IHistoryProvider; PR 3.W will register the Wonderware sidecar as a router
source; PR 7.2 retires the legacy fallback entirely.
44 alarm + history + integration tests pass.

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.
