Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes
project bookkeeping IDs (task/tracking refs) from shipped code comments,
so the docs read cleanly and CommentChecker is quiet except for known
false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc).
Doc/comment-only; no logic changed; solution builds clean.
AdminUI driver-instance pages serialized enum config fields (S7 CpuType,
Modbus DataType/Region, AbCip PlcFamily, ...) as JSON *numbers* because each
page's _jsonOpts lacked a JsonStringEnumConverter. The driver factories,
however, deserialize into string-typed DTOs (+ lenient ParseEnum) and throw
when binding a JSON number to a string? — so an AdminUI-authored config
containing any enum field produced a blob the driver could not parse,
faulting the driver on deploy. Proven end-to-end for S7 and Modbus; latent
for AbCip/AbLegacy/TwinCAT/FOCAS/Galaxy/Historian. Only OpcUaClient was safe
(its factory + probe already carried the converter).
Add JsonStringEnumConverter to all 9 driver-instance pages' _jsonOpts and the
8 missing driver probes' _opts (factories unchanged — already string-via-
ParseEnum; strictly more permissive, also lets pages load hand-seeded
string-enum configs back into the form).
Also fix DriverProbeHandshakeE2eTests.AbCip_Green_AgainstSim to probe a real
sim tag (TestDINT) — the no-tags @raw_cpu_type fallback is rejected by the
ab_server sim with ErrorBadParam (a real ControlLogix returns ErrorNotFound,
which the probe treats as reachable; hardware-gated follow-up).
Tests: reflection guard over all driver pages' _jsonOpts (AdminUI.Tests);
factory round-trip + numeric-form-throws guards for S7 and Modbus.
Found by running the never-before-run FB-9/FB-10 live verifies.
Two bugs caught by live verification against the mxaccessgw at 10.100.0.48:5120:
- MaxAttempts=1 produced an invalid Polly RetryStrategyOptions -> the probe failed
on every real gateway. Removed the Retry override (matches GalaxyDriver); fail-fast
is already guaranteed by the TCP preflight + the per-call deadline.
- A rejected key surfaces as a typed MxGatewayAuthenticationException, not a raw
RpcException, so 'auth-rejection = reachable' was bypassed. Catch the typed auth/
authorization exceptions -> Ok=true.
Adds DriverProbeHandshakeE2eTests: direct-probe, skip-gated cross-protocol green/red
discrimination (Modbus, OpcUaClient, Galaxy + a local real OPC UA server).
The driver/factory/seed use 'GalaxyMxGateway' (legacy 'Galaxy' was retired),
but the AdminUI editor router, GalaxyDriverPage, address picker, identity
dropdown, the Galaxy browser/probe, and DraftValidator still keyed on 'Galaxy'.
Result: the seeded GalaxyMxGateway driver couldn't be edited ('no editor
registered'), UI-created Galaxy drivers wrote a type with no factory, and a
SystemPlatform-bound GalaxyMxGateway driver failed publish validation.
Align all stragglers to GalaxyMxGateway (+ failing-test-first DraftValidator
coverage). ShouldStub's 'Galaxy' legacy safety-net left intact.
ModbusDriverProbe.DriverType was "Modbus" but the AdminUI's
ModbusDriverPage persists DriverInstance.DriverType = "ModbusTcp".
GalaxyDriverProbe used the runtime DriverTypeName constant
("GalaxyMxGateway") but the AdminUI saves "Galaxy". The probe DI
lookup is case-insensitive but not name-insensitive, so Test
Connect would fail to find a probe for these two drivers.
Cheap-and-fast probe: open TCP socket to the configured endpoint,
close immediately. Surfaces SocketError on failure, latency on
success, "timed out" on caller cancel. Sufficient for the AdminUI
Test Connect "can we reach the host?" question. Richer protocol-
level probes (OPC UA session open, FOCAS handshake, gRPC ping)
are a documented follow-up. Each probe registered as
AddSingleton<IDriverProbe, X> in DriverFactoryBootstrap so they
flow through DI into AdminOperationsActor.
Historian.Wonderware returns a clean "TCP probe not applicable"
result because it communicates over a Windows named pipe, not TCP.
Also adds OpcUaClient + Historian.Wonderware.Client project
references to Host.csproj (both were missing from the driver
ItemGroup).
