The first and only thing in the MTConnect workstream that exercises the driver
against a real Agent; everything else runs on canned XML.
Fixture (Docker/): two services, both stock images with this folder bind-mounted.
- `agent` mtconnect/agent:2.7.0.12 on :5000. NOTE the repo name: the source
project is mtconnect/cppagent but the PUBLISHED image is
mtconnect/agent; mtconnect/cppagent does not exist on Docker Hub.
- `adapter` a stdlib SHDR feeder. Required, not optional: the agent image ships
only the binary + schemas/styles, so a lone Agent answers /probe and
then reports every observation UNAVAILABLE forever, which can prove
nothing about reads or streaming.
Devices.xml seeds one DataItem per inference branch (SAMPLE+units, TIME_SERIES,
PART_COUNT/LINE_NUMBER, controlled vocab, DATA_SET, CONDITION), gives every named
item `name != id` (the inverse of the hand-authored unit fixtures), and leaves one
EVENT permanently unfed so UNAVAILABLE -> BadNoCommunication has a live subject.
Suite (12 tests) asserts STRUCTURALLY against the Agent's own /probe response, never
by literal id, so it survives an edit to Devices.xml and can be pointed at a real
machine tool via MTCONNECT_AGENT_ENDPOINT. It skips cleanly (12/12) when no Agent
answers, and each test carries a hard [Fact(Timeout)] so a half-up fixture cannot
wedge a build.
Three findings from bringing the fixture up, each now pinned in a comment:
- agent.cfg must be pure ASCII; one non-ASCII byte in a COMMENT makes the config
parser reject the whole file with a bare "Failed / Stopped at line: N" and exit.
- `sampleCount` is an attribute of a TIME_SERIES observation, not of a DataItem
declaration. A real Agent meeting one on a declaration DROPS THE ENTIRE DATA ITEM
from the device model, so the inference only ever sees null and a live TIME_SERIES
tag is always variable-length. Asserted, not ignored.
- The Agent's own <Agent> self-model publishes update-rate SAMPLEs that tick whether
or not any adapter is attached. Excluding them is load-bearing: with them included
the "live stream delivered a changed value" test passed with the fixture's data
source deliberately stopped.
MTConnectError-under-HTTP-200 is NOT covered live and cannot be: cppagent 2.7 answers
an unknown device 404 and an out-of-range sequence 400, each with a well-formed error
body. That shape stays canned-only, and the suite says so.
Adds a project-owned, controllable Sparkplug B edge node (SparkplugEdgeNode) that
encodes with the SAME generated Tahu schema the driver decodes with — so the live
gate checks encode/decode symmetry rather than the driver against itself — and
drives the §3.6 matrix end-to-end over the real TLS+auth Mosquitto fixture.
The simulator frames its topics independently of SparkplugTopic.Format: a
simulator borrowing the parser's formatter could not detect a bug in it, because
both sides of the comparison would be wrong together. It registers a real NDEATH
Last Will at CONNECT, restarts seq at 0 on NBIRTH, publishes DATA metrics as
alias-only, carries bdSeq per session, and encodes signed ints as two's
complement in the unsigned proto field.
SparkplugLiveTests (Category=LiveIntegration, env-gated, skip-clean) covers:
birth -> alias-only data -> OnDataChange under the RawPath; late-join rebirth
NCMD honoured by an independent decoder; alias reuse across a rebirth routing by
metric NAME; a stale-bdSeq NDEATH ignored while the current one stales; the real
broker-published Will staling and the next birth restoring; seq wrap 255->0
requesting no rebirth while a deliberate gap does; and the browser's passive
window asserted ON THE WIRE (a third client watching spBv1.0/{group}/NCMD/#),
plus RequestRebirthAsync node-vs-group enumeration.
Two things make the suite falsifiable rather than decorative: the seq-wrap test
builds its ingestor with rebirthDebounce: TimeSpan.Zero (at the shipped 10s
default a wrap-triggered NCMD would be swallowed and the test would pass for the
wrong reason) and pairs the silence with a deliberate gap that must produce one;
and the passivity assertion observes the broker rather than the session's own
publish counter, which can only see the seam it guards.
Docker/docker-compose.yml gains a profile-gated `sparkplug-sim` service running
the same engine standalone against the same broker (TLS, CA-pinned) — a manual
driving aid for the AdminUI picker, deliberately NOT a test dependency, since the
matrix needs an edge node it can command mid-test. Its app directory is publish
output (publish-simulator.sh), gitignored like secrets/.
Offline: 15 skipped, 0 failed with no env set. Live: 15/15 passed against
10.100.0.35:8883. Falsifiability spot-check: mutating AliasTable.RebuildFromBirth
to merge instead of replace, and neutering SparkplugCodec.ReinterpretSigned for
Int32, turned exactly the two corresponding tests red and nothing else; both
mutations reverted.

Adds the MQTT driver integration-test project: an eclipse-mosquitto fixture running
auth AND TLS (allow_anonymous false on both listeners), a mosquitto_pub-based JSON
publisher emitting retained messages, a cert/password generator script whose output is
gitignored, and a live suite gated on MQTT_FIXTURE_ENDPOINT that skips clean offline.
The fixture is never anonymous by design: an anonymous broker would let the driver's
TLS/CA-pin and auth paths go untested, and those fail silently. The CA-pin leg carries
its own falsifiability control (a foreign CA generated in-process must be rejected).
Live gate on 10.100.0.35: 7/7 passed. It found a driver defect, reported not fixed
here (src/ is out of this task's scope): MqttConnection.ConnectAsync RETURNS NORMALLY
when Mosquitto rejects a CONNECT as not-authorized -- MQTTnet 5 does not throw on an
unsuccessful CONNACK, so a wrong broker password yields DriverState.Healthy from
InitializeAsync. The auth-negative test therefore asserts the invariant that holds
either way (no session is ever established) and documents the finding.
Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
MQTT has no discovery protocol, so the AdminUI address picker learns the topic
space the only way there is: subscribe to the wildcard and accumulate what
arrives. MqttBrowseSession serves that observation as a segment tree (split on
'/'); MqttDriverBrowser opens it with a distinct "{clientId}-browse-{guid8}"
identity under a 5-30 s clamped budget.
Browsing publishes NOTHING - the load-bearing safety property, since the picker
runs against a live plant broker. Every outbound message must route through the
single PublishAsync seam that counts into PublishCountForTest; P2's operator-
triggered Sparkplug rebirth is the one intended exception. Sparkplug mode fails
fast rather than serving a raw spBv1.0 topic tree that looks like a metric tree.
Deviation from the plan's ref list: the project also references .Driver so the
browse CONNECT reuses MqttConnection.BuildClientOptions (TLS posture, CA-pin
chain validator, credentials). A second copy would be a security divergence.
Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
Walks schemas -> tables/views -> columns via ISqlDialect's catalog SQL, with
@schema/@table bound as parameters at every level. Column leaves carry the
dialect-mapped DriverDataType in the attribute side-panel (ViewOnly, read-only
v1).
The NodeId encoding deliberately departs from the design sketch's literal
`schema.table|column`: SQL Server permits `.` and `|` inside a quoted
identifier, so that form mis-parses (main.a.b|c reads equally as schema
`main`+table `a.b` and schema `main.a`+table `b`) and silently binds an
operator's tag to the wrong column. SqlBrowseNodeId encodes
`<kind>:<part>[|<part>...]` with `\`/`|` escaped and the kind prefix carrying
the arity; it is public because the picker body decodes it back.
The session owns the connection it is handed and closes it on dispose -- the
registry-held session is the only lifetime hook, so a non-owning session would
leak one pooled connection per reaped picker. Per-call work stays bounded by
the AdminUI's existing 20s linked CTS (BrowserSessionService.PerCallTimeout);
no second deadline is invented here.

New Driver.Calculation project + CalculationEvaluator, mirroring the
VirtualTag RoslynVirtualTagEvaluator: source-hash compile cache
(CompiledScriptCache), 2 s TimedScriptEvaluator, passthrough fast-path,
single-tag mode (ctx.SetVirtualTag dropped + logged), sandbox/compile/
timeout/throw all surfaced as VirtualTagEvalResult.Failure for WP7 to map
to Bad quality. IScriptCacheOwner.ClearCompiledScripts for the deploy
generation boundary. 11 parity unit tests. Both projects added to the
solution. Evaluator + tests only — driver shell / registration is WP7.

The HistorianGateway driver is now the sole historian read/write+alarm backend, so the
Wonderware sidecar projects are dead code. Removes the 5 Wonderware projects (driver,
.Client, .Client.Contracts, + their 2 test projects) from the solution and tree, and fully
retires the vestigial 'Historian.Wonderware' driver type (UI/probe-only; it had no driver
factory): the Host probe registration, the AdminUI driver-config surface (driver page,
tag-config editor/model/validator entry, address picker/builder, driver-type catalog +
dropdown + edit-router entries), and their tests. Prunes the now-unused Wonderware
connection fields (Host/Port/UseTls/ServerCertThumbprint/SharedSecret) from
AlarmHistorianOptions (keeping Enabled + the SQLite store-and-forward knobs) and refreshes
the stale XML docs that named Wonderware as the production backend.
Claude-Session: https://claude.ai/code/session_012SDSQ3AcaXqPcBtDESBRii
Move WonderwareHistorianClientOptions to a new
Driver.Historian.Wonderware.Client.Contracts sibling project. The record
had no using directives and uses only primitive types (string, TimeSpan)
so the contracts project is dependency-free.
Convert one doc-comment reference:
<see cref="WonderwareHistorianClient"/> → <c>WonderwareHistorianClient</c>
per the approved decision — no compilable usings were present.
The runtime Driver.Historian.Wonderware.Client project gains a
ProjectReference to .Contracts; the .slnx is updated accordingly.
Move GalaxyDriverOptions (and nested records GalaxyGatewayOptions,
GalaxyMxAccessOptions, GalaxyRepositoryOptions, GalaxyReconnectOptions)
from Config/GalaxyDriverOptions.cs into a new Driver.Galaxy.Contracts
sibling project at the contracts root (no Config/ subdirectory). The
existing namespace ZB.MOM.WW.OtOpcUa.Driver.Galaxy.Config is preserved
unchanged — it is a runtime ABI concern and all consumers already import
it via the namespace qualifier.
No doc-comment substitutions required — the only cref in the file
(<see cref="ApiKeySecretRef"/>) is an intra-type parameter reference
that resolves within the contracts project itself.
The options file had no using directives and no NuGet type surface;
the contracts project is dependency-free. The runtime Driver.Galaxy
project gains a ProjectReference to .Contracts; the .slnx is updated
accordingly.
Move OpcUaClientDriverOptions and all companion enums (OpcUaTargetNamespaceKind,
OpcUaSecurityMode, OpcUaSecurityPolicy, OpcUaAuthType) to a new
Driver.OpcUaClient.Contracts sibling project. The options file had no
using directives — all types were defined in the same file — so no
NuGet mirror enum pattern was required.
Convert two doc-comment references:
<see cref="OpcUaClientDriver.InitializeAsync"/> → <c>OpcUaClientDriver.InitializeAsync</c>
<see cref="OpcUaClientDriver.ValidateNamespaceKind"/> → <c>OpcUaClientDriver.ValidateNamespaceKind</c>
per the approved decision — no compilable usings were present.
The runtime Driver.OpcUaClient project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
Move FocasDriverOptions (and companion option types), FocasCncSeries,
and the FocasDataType enum to a new Driver.FOCAS.Contracts sibling
project. FocasDataTypeExtensions (which uses DriverDataType from
Core.Abstractions) stays in the runtime driver as FocasDataTypeExtensions.cs.
Convert two doc-comment references:
<see cref="FocasDriver.InitializeAsync"/> → <c>FocasDriver.InitializeAsync</c>
<see cref="FocasAddress.TryParse"/> → <c>FocasAddress.TryParse</c>
per the approved decision — no compilable usings were present in the
moved files.
The runtime Driver.FOCAS project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
Introduces Driver.S7.Contracts (dependency-free POCO project) and moves
S7DriverOptions / S7ProbeOptions / S7TagDefinition / S7DataType into it.
Adds S7CpuType enum mirroring S7.Net.CpuType exactly (7 values with
explicit integer codes). Runtime S7CpuTypeMap bridges S7CpuType →
S7.Net.CpuType at the single Plc construction site in S7Driver.InitializeAsync.
S7DriverFactoryExtensions and S7CommandBase updated to use S7CpuType; test
files updated to match (S7_1500Profile, S7DriverScaffoldTests). AdminUI can
now reference Driver.S7.Contracts without pulling in S7netplus.
Move TwinCATDriverOptions and TwinCATDataType enum to a new
Driver.TwinCAT.Contracts sibling project. TwinCATDataTypeExtensions
(which uses DriverDataType from Core.Abstractions) stays in the
runtime driver as TwinCATDataTypeExtensions.cs.
Replace two doc-comment references:
<see cref="Core.Abstractions.PollGroupEngine"/> → <c>PollGroupEngine</c>
<see cref="TwinCATAmsAddress.TryParse"/> → <c>TwinCATAmsAddress.TryParse</c>
per the approved decision — no compilable usings were present.
The runtime Driver.TwinCAT project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
Move AbLegacyDriverOptions, AbLegacyDataType enum, and
AbLegacyPlcFamilyProfile (including AbLegacyPlcFamily enum) to a new
Driver.AbLegacy.Contracts sibling project. All three files are zero-dep
after splitting AbLegacyDataTypeExtensions (which uses DriverDataType
from Core.Abstractions) into a new file that stays in the runtime driver.
Drop the doc-comment <see cref="AbLegacyAddress.TryParse"/> reference and
replace with <c>AbLegacyAddress.TryParse</c> per the approved decision.
The PlcFamilies using directive is retained in the contracts project since
both namespaces live there.
The runtime Driver.AbLegacy project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
Move AbCipDriverOptions (and AbCipDataType enum) to a new
Driver.AbCip.Contracts sibling project. AbCipDataTypeExtensions
(which uses DriverDataType from Core.Abstractions) stays in the
runtime driver as AbCipDataTypeExtensions.cs.
Replace two doc-comment <see cref="Core.Abstractions.IAlarmSource"/>
and <see cref="Core.Abstractions.IHostConnectivityProbe"/> with <c>X</c>
per the approved decision — no compilable using was present.
The runtime Driver.AbCip project gains a ProjectReference to .Contracts;
the .slnx is updated accordingly.
Move ModbusDriverOptions (and companion option types) to a new
Driver.Modbus.Contracts sibling project. The contracts project
references only Driver.Modbus.Addressing (itself zero-dep and
Admin-safe) because ModbusDriverOptions.Probe/Family/Region
properties use enum types that live there.
Drop 'using ZB.MOM.WW.OtOpcUa.Core.Abstractions' and replace
<see cref="IHostConnectivityProbe"/> with <c>IHostConnectivityProbe</c>
per the approved decision — the using was doc-comment-only.
The runtime Driver.Modbus project gains a ProjectReference back to
.Contracts; the .slnx is updated accordingly.
Builds TwoNodeClusterHarness: two in-process Host-equivalent nodes sharing
an in-memory ConfigDb. Forms a 2-member Akka cluster. ClusterFormationTests
proves both nodes see each other as admin+driver role members.
Fixes a real production bug uncovered while wiring the harness — Program.cs
ran two separate ActorSystems (one from AddOtOpcUaCluster.AkkaHostedService
with cluster HOCON, one from Akka.Hosting.AddAkka with bare HOCON). Cluster
singletons landed on the bare ActorSystem and could not actually form a
cluster ("Configuration does not contain `akka.cluster` node").
Consolidation:
- AddOtOpcUaCluster now only binds AkkaClusterOptions + registers IClusterRoleInfo
- New WithOtOpcUaClusterBootstrap pushes embedded HOCON + Remote/Cluster options
into Akka.Hosting's AkkaConfigurationBuilder
- AkkaHostedService.cs deleted — Akka.Hosting now owns the lifecycle
- Program.cs + harness call WithOtOpcUaClusterBootstrap inside AddAkka
Why not WebApplicationFactory<Program>? Program.cs reads OTOPCUA_ROLES from
process env (shared across in-process WAFs); the harness replays Program.cs's
DI graph from a clean WebApplicationBuilder per node with per-node config
overrides. Same production extensions, isolated config + Kestrel + Akka ports.
Tests: 93 v2 tests pass (was 91 + 2 new cluster formation), 0 skipped.
Task 56: removes the legacy in-process Server + Admin Web project + their test
projects (Server.Tests, Admin.Tests, Admin.E2ETests). The fused OtOpcUa.Host
binary built across Phases 1-9 is now the sole production entry point.
What happened to the 47 legacy Admin Blazor pages: per follow-up F15, the
v1 architecture's draft/publish UX is replaced by v2's live-edit + snapshot-
deploy model, so a 1:1 migration is not meaningful. The mechanical move via
git mv preserves the history; service classes + page bodies that referenced
removed v1 types (ConfigGeneration, RedundancyRole, GenerationId) were
deleted. AdminUI now ships a minimal Home page + the v2 Deployments page.
Per-page rebuild against the v2 surface is tracked as F15. The v2 Deployments
page (Task 52) is the only first-party UI shipping in this PR.
Task 57: solution build green; 84+ tests green across active v2 + legacy
driver test projects.
Adds the empty project skeletons that subsequent v2 tasks fill in:
src/Core/ZB.MOM.WW.OtOpcUa.Commons (types, interfaces, message contracts)
src/Core/ZB.MOM.WW.OtOpcUa.Cluster (Akka.Hosting + cluster wiring)
src/Server/ZB.MOM.WW.OtOpcUa.Security (cookie+JWT auth, LDAP)
src/Server/ZB.MOM.WW.OtOpcUa.ControlPlane (admin-role cluster singletons)
src/Server/ZB.MOM.WW.OtOpcUa.Runtime (per-node driver actors)
src/Server/ZB.MOM.WW.OtOpcUa.OpcUaServer (OPC UA SDK application host)
src/Server/ZB.MOM.WW.OtOpcUa.AdminUI (Razor class library)
src/Server/ZB.MOM.WW.OtOpcUa.Host (single fused web binary)
Each project sets TreatWarningsAsErrors=true in its own csproj (per the
Directory.Build.props deviation note in the previous commit). NuGetAuditSuppress
entries cover transitive vulnerability advisories the new strictness surfaces:
- GHSA-g94r-2vxg-569j (OpenTelemetry.Api 1.9.0 via Akka.Cluster.Hosting/Tools)
- GHSA-h958-fxgg-g7w3 (Opc.Ua.Core 1.5.374.126 via OpcUaServer)
- GHSA-37gx-xxp4-5rgx + GHSA-w3x6-4m5h-cxqf (legacy advisories already accepted)
OpcUaServer pins OPCFoundation.NetStandard.Opc.Ua.Configuration to 1.5.374.126
via VersionOverride to match Opc.Ua.Server's transitive Opc.Ua.Core (same
constraint as the legacy Server project).
Runtime does NOT project-reference any concrete Driver.* assemblies; drivers
load reflectively at runtime (Phase 6). Runtime gets the IDriver contract
through Core.Abstractions instead.
Host's Microsoft.Extensions.Hosting.WindowsServices is conditional on the
Windows OS so the project builds on macOS dev machines.
Build verification: dotnet build -> 438 warnings (all pre-existing xUnit1051
in legacy Server.Tests/Admin.Tests), 0 errors. Closes Task 9 (build green
smoke check, no separate commit).
- Driver.FOCAS.Cli-001: WriteCommand.ParseValue now wraps numeric
FormatException / OverflowException as CliFx CommandException with
the offending value.
- Driver.FOCAS.Cli-002: SubscribeCommand's OnDataChange handler and the
banner both take a writeLock so notification-callback and main-thread
writes can't interleave; handler exceptions are warn-and-swallow.
- Driver.FOCAS.Cli-003: FocasCommandBase.ValidateOptions rejects
--cnc-port outside 1..65535, non-positive --timeout-ms, and
non-positive --interval-ms; ExecuteAsync calls it first.
- Driver.FOCAS.Cli-004: 'await using var driver' is the sole driver
disposal path; dropped the redundant explicit await ShutdownAsync.
- Driver.FOCAS.Cli-005 (Deferred): the fix lives in
Driver.Cli.Common.SnapshotFormatter — explicitly naming the
status-code shortlist there benefits every driver CLI. Left as a
Driver.Cli.Common follow-up.
- Registered the new tests/Drivers/Cli/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Cli.Tests
project in ZB.MOM.WW.OtOpcUa.slnx.

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.

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

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.

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.
