mxaccessgw 488649c+ acknowledges by AuthenticateUser as the operator and
writing <alarm>.AckMsg, so AcknowledgeAlarmRequest now needs a real Galaxy
operator_user + operator_domain + operator_password. The OPC UA data plane is
API-key/anonymous and carries no Galaxy password, so the driver resolves the
account per ack:
1. the session's API key's Galaxy ack identity, set on AdminUI /apikeys and
held ONLY in the encrypted Secrets store
(otopcua/apikeys/<keyId>/galaxy-ack-{user,password}); a key with a user but
no password secret is refused, never silently downgraded;
2. else the driver instance's AlarmAck fallback account (DriverConfig
FallbackUser/FallbackDomain/FallbackPasswordSecretRef; secret:/${secret:}/
env:/file:/dev: only — a literal is refused);
3. else DriverOperationRefusedException: nothing is sent, never an empty
operator_user. Refusals are excluded from the resilience retry/breaker.
- Pins ZB.MOM.WW.MxGateway.Client/Contracts 0.2.1 -> 0.3.0 (vendored into
nuget-packages/ from the Gitea feed, per the local-mxgw source mapping).
- The session ApiKeyId (not a secret) rides NativeAlarmAck ->
RouteNativeAlarmAck -> RouteAlarmAck -> AlarmAcknowledgeRequest; the password
is resolved in the driver and never travels through actor messages.
- The OPC UA principal + key id are appended to the AckMsg comment
("[OPC UA: <principal>, key <id>]") and logged, so a shared fallback
account does not lose who acknowledged.
- Password never logged: GalaxyAckCredential.ToString omits it, the
acknowledger scrubs it from every gateway message it echoes and withholds
any exception that echoes it; audit rows carry only the key id.
- AdminUI: /apikeys "Ack identity" editor (set/remove; delete-key clears it),
Galaxy driver form gains the fallback section.
- Synchronous OPC UA status for a refusal is follow-up #760 (the native ack
path is fire-and-forget after the Part 9 method returns).
Tests: request mapping (password populated), password absent from logs and
exception text (mutation-checked), key-mapped / fallback / refused paths at
resolver and driver level, breaker non-trip, key-id propagation through node
manager and DriverHostActor, AdminUI service + form round-trip.
Closes#749
Clears CommentChecker findings in src/ (3,280 -> 209, the remainder being false
positives like PLC-5/IEEE-754/M0.0) by adding missing summaries/params/returns,
normalising inheritdoc usage, and removing Gitea/review tracking IDs while keeping
the rationale they annotated. Comment-only: comment-stripped sources are identical
to the parent commit.
After an OpcUaClient respawn an upstream inactive+unacked condition went out as
Retrigger+Clear (duplicate Activated+Cleared rows, Active flicker), and a
first-sight inactive+acked one as Unspecified (an Activated row for an inactive
alarm; a retained-Active host condition never cleared).
- New AlarmTransitionKind.InactiveUnacknowledged: one projection, rows only for
what changed (Activated+Cleared from acked, Cleared from active+unacked, none
when already inactive+unacked).
- OpcUaClient uses it for moves into inactive+unacked; first sight of an
inactive condition is InactiveUnacknowledged or Clear+Acknowledge, flagged.
- Projector: a flagged Acknowledge on an already-acked condition writes no row.
- E2E tests through DriverHostActor.ForwardNativeAlarm (red-proven).

- AlarmTransitionKind.ActiveAcknowledged (appended): active AND acked applied as ONE projection.
Galaxy ActiveAcked snapshot entries and OpcUaClient inactive->(active,acked) use it; the
projector writes 'Activated' only if not already active, 'Acknowledged' only if not acked.
- AlarmEventArgs.IsRestatement (optional, default false): set only by Galaxy snapshot entries
and OpcUaClient first sight. A flagged Retrigger on an Active+unacked condition with the same
message and severity, or a flagged Clear on an inactive condition, writes no /alerts row.
- NativeAlarmProjector reports the history rows per transition; ForwardNativeAlarm writes one
row per entry. Unflagged sources (FOCAS/MTConnect/AbCip, live Galaxy) are unchanged.
- Tests: projector rules each with a must-write control; OpcUaClient transition table;
Galaxy feed/driver mapping; Galaxy + OpcUaClient end-to-end through DriverHostActor.

AlarmEventArgs gains optional OpcUaSeverity (supersedes the four-bucket mapping, clamped
1..1000) and QualityStatusCode (projected onto the condition's Quality). An Unspecified-kind
event carrying a quality is a quality-only annotation: the host updates the condition but
publishes no alerts row. Both default null, so every existing native source is unchanged.

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.
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
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.
