fix(fixtures): correct Java Gradle task name in cross-language smoke matrix

The smoke-matrix Java commands used 'gradle :mxgateway-cli:run', but the subproject is ':zb-mom-ww-mxgateway-cli' (settings.gradle). Verbatim execution would fail; CrossLanguageSmokeMatrixTests validates shape only, so CI did not catch it. Resolves audit finding F-10-2.

SignalR hubs at `/hubs/{snapshot,alarms,events}` accept either the cookie or a 30-minute bearer minted at `/hubs/token`. `Dashboard:AllowAnonymousLocalhost` bypasses auth on loopback when enabled.

 # MXAccess Gateway — Documentation Audit Findings
 Synthesized from the 13 audit fragments under `docs/audit/fragments/`. This report drives the fix phase (Tasks 15–22). It is read-only with respect to code and the audited docs; the only artifact produced is this file.
 ## 1. Summary
 Total findings: **186** across 13 clusters.
 ### Counts by verdict
 | Verdict | Count |
 |---|---|
 | accurate | 109 |
 | stale | 27 |
 | wrong | 33 |
 | unverifiable | 6 |
 | gap | 24 |
 (Note: a small number of cluster-08 entries are verdict-tagged `accurate` in the fragment body while the prose flags a phrasing nuance; they are counted as `accurate`.)
 ### Counts by severity
 | Severity | Count |
 |---|---|
 | high | 33 |
 | medium | 33 |
 | low | 120 |
 ### Per-cluster table
 | Cluster | #high | #med | #low | #gap (any sev) |

 ## 2. Global substitutions table
 Mechanical string replacements that recur across multiple docs or are pure find-and-replace. The "applies to" list contains **only** files the fragment evidence shows actually contain the old string. CLAUDE.md is a living doc and is listed explicitly where the evidence targets it. Per the audit rules, design-history / plan docs (cluster 13) are **excluded** from these applies-to lists — their term occurrences are historical records, not corrected here (only their broken internal cross-refs are fixed, in Task 22).

 Notes:
 - The scope-shorthand renames (`session`→`session:open`/`session:close`, `invoke`→`invoke:read`/`invoke:write`/`invoke:secure`, `event`→`events:read`, `metadata`→`metadata:read`) are **not** a single 1:1 mechanical substitution (one shorthand maps to multiple canonical scopes), so they are handled as judgment edits in Tasks 18/20, not in this table. The affected docs are gateway.md (L662–663), CLAUDE.md (L35, L117, L248-evidence), docs/Authentication.md (L99, L187–208).
 - The `wwwroot/css/dashboard.css` → `site.css` rename is dashboard-cluster-specific (single doc family) and is handled in Task 19.

 ## 3. Out-of-prose-scope flags
 These findings target **non-`.md`** files. They are real bugs but outside this prose audit. **Flag only — recommend separate fix.** Do not schedule them for doc-editing tasks.
 | Finding ID | File | Issue | Severity |
 |---|---|---|---|
 | F-10-2 | `clients/proto/fixtures/smoke/cross-language-smoke-matrix.json` | Every Java command entry uses `gradle :mxgateway-cli:run`; the Gradle subproject is `:zb-mom-ww-mxgateway-cli`. Verbatim execution fails; `CrossLanguageSmokeMatrixTests` does not check the literal task name, so it passes CI undetected. | high |
 (No other fragment finding targets a non-`.md` artifact for an edit; `proto-inputs.json`, `appsettings.json`, source `.cs/.rs/.go/.gradle/.toml` etc. appear only as evidence, not as edit targets.)

 ## 4. Per-doc findings
 Findings grouped by DOC, ordered high→low severity within each doc. IDs are `F-<cluster#>-<n>` numbered in fragment order within the cluster.
 ### gateway.md
 - **F-01-13** — L231–248 — wrong/high — `WorkerEnvelope` proto block (field type/numbers/names). EVIDENCE: `mxaccess_worker.proto` has `string correlation_id = 4` (not uint64); body fields `gateway_hello=10 … worker_fault=20`; names differ (`command`→`worker_command`, `event`→`worker_event`); missing `worker_shutdown_ack=17`. FIX: replace the block with actual proto content.
 - **F-01-1** — L737–769 — stale/medium — short project names in layout. FIX: use fully-qualified `src/ZB.MOM.WW.MxGateway.*` names (see substitutions).
 - **F-01-2** — L898–913 — stale/medium — session state machine missing `Handshaking`. FIX: insert `-> Handshaking` between `WaitingForPipe` and `InitializingWorker`.
 - **F-01-12** — L301–314 — stale/medium — second session state-machine diagram also missing `Handshaking`. FIX: same insertion in both diagrams.
 - **F-01-3** — L119–121 — stale/medium — scope rejection lists shorthand scope names. FIX: canonical scope strings (judgment, see Task 18 note).
 - **F-01-4** — L119–121 — stale/low — dashboard route list omits `/browse` and `/login`. FIX: add them.
 - **F-01 accurate set** — multiple (L88–94, 108, 110–122, 129–130, 162–210, 266–273, 646–650, 1023–1025, 2–19) — accurate/low — flag only.
 ### docs/GatewayProcessDesign.md
 - **F-01-7** — L249–255 — wrong/high — `/dashboard`-prefixed route table. FIX: replace with actual no-prefix routes (see substitutions).
 - **F-01-8** — L689 — stale/low — `Dashboard:AllowAnonymousLocalhost` missing `MxGateway:` root prefix. FIX: standardize to `MxGateway:Dashboard:AllowAnonymousLocalhost`.
 - **F-01-9** — L854–855 — accurate/low — worker `ExecutablePath` default (separator style only). Flag only.
 - **F-01 accurate set** — L62–93, 100–105, 223–229, 291–299, 408–410, 420–475, 527–530, 713–719, 864–893 — accurate/low — flag only.
 ### docs/DesignDecisions.md
 - **F-01-6** — L360–363 — wrong/high — claims dashboard auth is "API-key-backed dashboard authentication with `admin` scope." EVIDENCE: `DashboardAuthenticator.cs` is LDAP-backed with `GroupToRole`. FIX: rewrite to LDAP-backed + `GroupToRole`→`Admin`/`Viewer`; keep `AllowAnonymousLocalhost` note.
 - **F-01-10** — L36 — unverifiable/low — interop assembly version/PKT not hard-coded in repo. Flag only.
 - **F-01-11** — L36–48 — accurate/low — COM class/CLSID/ProgID/paths. Flag only.
 - **F-01-14** — L55 — accurate/low — `ArchestrA.MXAccess.dll` casing. Flag only.
 - **F-01 accurate set** — L85–95, 217–225 — accurate/low — flag only.
 ### docs/WorkerSta.md
 - **F-02-1** — L23–31 — wrong/medium — STA thread name `ZB.MOM.WW.MxGateway.Worker.STA`. FIX: `MxGateway.Worker.STA` (prose + snippet) (substitution).
 - **F-02-3** — L144 — wrong/medium — `InvokeAsync` throws `InvalidOperationException`. EVIDENCE: throws `StaRuntimeShutdownException` (subtype). FIX: name the subtype and explain why the distinction matters.
 - **F-02-19** — L141–148 — stale/medium — shutdown drain sequence implies single post-stop drain. EVIDENCE: `CancelQueuedCommands` runs inside `ThreadMain` finally before `stoppedEvent.Set()`, and again in `Shutdown()`; drain happens twice. FIX: revise steps 3–4.
 - **F-02-12** — L14 — stale/low — "Bounded asynchronous queue." EVIDENCE: plain `Queue<T>` under lock with async drain loop. FIX: "Bounded queue with an async drain loop."
 - **F-02 accurate set** — L34, 56, 63–78, 82–99, 108, 149 — accurate/low — flag only.
 ### docs/MxAccessWorkerInstanceDesign.md
 - **F-02-4** — L122 — wrong/high — `Success` (exit 0) = "bootstrap options valid." EVIDENCE: actual meaning "pipe session ran to a clean close." FIX: correct Success row; note `WorkerBootstrapResult.Succeeded` is a parse-phase gate distinct from exit 0.
 - **F-02-5** — L119–128 — stale/high — exit-code table missing codes 5 (`PipeConnectionFailed`) and 6 (`ProtocolViolation`). FIX: add both rows.
 - **F-02-6** — L134–160 — stale/high — component tree class names wrong (`WorkerHost`→`WorkerApplication`, `PipeClient`→`WorkerPipeClient`, `FrameReader/Writer`→`WorkerFrameReader/Writer`, `WorkerProtocol`→`WorkerContractInfo`, `StaCommandQueue`→`StaCommandDispatcher`, `MessagePump`→`StaMessagePump`, `StaWatchdog`→`WorkerPipeSession`, `MxAccessCommandDispatcher`→`MxAccessCommandExecutor`, `SafeArrayConverter`→part of `VariantConverter`, `StatusProxyConverter`→`MxStatusProxyConverter`, `HResultMapper`→`HResultConverter`). FIX: rewrite tree.
 - **F-02-15** — L97 — wrong/high — `MXGATEWAY_WORKER_LOG_CONTEXT` env var documented. EVIDENCE: not read anywhere. FIX: remove or mark unimplemented.
 - **F-02-16** — L86–99 — wrong/high — same `MXGATEWAY_WORKER_LOG_CONTEXT` in bootstrap sequence. FIX: flag-only duplicate of F-02-15.
 - **F-02-22** — L134–160 — gap/high — no alarm subsystem in component tree. FIX: add "Alarm Subsystem" section (consumer, poll loop, dispatcher, sink).
 - **F-02-2** — L254 — wrong/medium — STA thread name. FIX: `MxGateway.Worker.STA` (substitution).
 - **F-02-20** — L134–160 — stale/medium — `MxAccess` subtree class names (`MxAccessCommandDispatcher` does not exist; add `MxAccessStaSession`, `MxAccessCommandExecutor`, alarm sinks). FIX: update.
 - **F-02-23** — L336–338 — gap/medium — event-sink subscription list omits alarm events. FIX: add `MxAccessAlarmEventSink`.
 - **F-02-18** — L368–375 — stale/low — `MxAccessEventQueue.Enqueue` also throws `MxAccessEventQueueOverflowException`. FIX: note thrown exception.
 - **F-02-26** — L151 — accurate/low — `MxAccessSession` exists. Flag only.
 - **F-02 accurate set** — L271–286, 656–660 — accurate/low — flag only.
 ### docs/WorkerBootstrap.md
 - **F-02-7** — L146 — stale/medium — stderr/stdout-capture rationale. EVIDENCE: launcher redirects neither stream. FIX: replace rationale; the env-var-secrecy reason is the accurate one.
 - **F-02-25** — L5–6 — stale/low — "short-lived child." FIX: "per-session child process."
 - **F-02 accurate set** — L7–8, 48–54, 105, 113–120, 155–159, 181–193 — accurate/low — flag only.
 ### docs/WorkerConversion.md
 - **F-02-21** — L1–262 — gap/medium — inverse projection (`ConvertToComValue`/`ConvertToComArray`, write path) undocumented. FIX: add "Inverse projection for COM writes" section.
 - **F-02-11** — L225 — stale/low — engine-error ranges implied contiguous; gaps exist (35,45,46 / 58,59). FIX: "selected detail codes in the ranges …".
 - **F-02 accurate set** — L17–18, 112–135, 178 — accurate/low — flag only.
 ### docs/WorkerFrameProtocol.md / docs/WorkerProcessLauncher.md
 - All findings accurate/low (F-02 frameproto and launcher accurate set: WorkerFrameProtocol L14–53; WorkerProcessLauncher L18–64). Flag only.
 ### docs/Sessions.md
 - **F-03-22** — gap/high — orphan cleanup (`OrphanWorkerCleanupHostedService` → `OrphanWorkerTerminator.TerminateOrphans` on startup, best-effort) undocumented. FIX: add "Gateway Restart / Orphan Cleanup" section.
 - **F-03-21** — L230 — wrong/high — invents metric names `KillCount`/`ShutdownCount`. EVIDENCE: actual counter is `mxgateway.workers.killed`. FIX: replace with real counter via `GatewayMetrics.WorkerKilled`.
 - **F-03-1** — L9 — wrong/medium — "All four interfaces" (only three exist) and omits `SessionLeaseMonitorHostedService`. FIX: "three interfaces"; list two hosted services.
 - **F-03-2** — L265–276 — stale/medium — DI snippet omits `SessionLeaseMonitorHostedService`. FIX: add the registration line.
 - **F-03-3** — L232–259 — stale/medium — `ShutdownAsync` snippet predates Server-045/046; fallback now routes via `KillWorkerAsync`. FIX: replace snippet.
 - **F-03-4** — L55–59 — stale/medium — `KillWorkerAsync` no longer calls `GatewaySession.KillWorker` directly; now `KillWorkerWithCloseGateAsync` (acquires `_closeLock`). FIX: update.
 - **F-03-12** — L163–188 — stale/medium — open-failure rollback order omits conditional `SessionRemoved()` (Server-006). FIX: note the conditional metric call before `ReleaseSessionSlot`.
 - **F-03-19** — L230 — stale/medium — `GatewaySession.KillWorker` no longer the entry point from `SessionManager`. FIX: clarify `KillWorkerWithCloseGateAsync` is the path.
 - **F-03-23** — gap/medium — `AllowMultipleEventSubscribers=true` rejected at startup by `GatewayOptionsValidator`. FIX: note startup-validation refusal.
 - **F-03-7** — L265 — wrong/medium — "the hosted service" (singular). FIX: "two hosted services."
 - **F-03-20** — L279 — stale/low — registration-order reasoning. FIX: note two hosted services + DI ordering caveat.
 - **F-03-24** — gap/low — `_items` registration dictionary undocumented. FIX: add paragraph.
 - **F-03-25** — gap/low — `MaxPendingCommandsPerSession` (128) cap undocumented. FIX: add note.
 - **F-03-26** — gap/low — `KillWorkerWithCloseGateAsync` unmentioned. FIX: mention in Close section.
 - **F-03 accurate set** — L15–127, 134–227, 195–197, 197 (lease/sweep) — accurate/low — flag only.

 - **Fix (JavaStyleGuide.md):** F-12-4 (package root — substitution).
 - **Fix (PythonStyleGuide.md):** F-12-5 (paths — substitution), F-12-7 (env var).
 - **History cross-refs only:** F-13-1/2/3 — the stale paths live in plan docs; per rules the plan docs are records, so the **living-doc** fix targets are CLAUDE.md L22 (`src/MxGateway.sln`), L57/L93 (`clients/dotnet/MxGateway.Client.sln`) — both substitution-covered under Task 15. Do **not** edit term occurrences inside the plan docs. F-13-4 is a flag-only inaccuracy in a record (no fix). F-13-5/6/7/22 are stale navigation line numbers in plans — flag only.
 - **Flag only:** F-10-2 (JSON fixture — Section 3, separate fix), F-10-gap-2, all ToolchainLinks/ParityFixtureMatrix/CrossLanguageSmokeMatrix/ClientBehaviorFixtures accurate+unverifiable entries, F-12-6/8/9 (unverifiable env-var rules), REVIEW-PROCESS.md and remaining accurate style-guide claims.
 ---
 ### Synthesis notes for the fix phase
 - **CLAUDE.md** is treated as a living doc: its auth findings (cookie, role, scopes, apikey subcommand) are scheduled under Task 18, and its build-path/sln findings (surfaced via the history cluster) are scheduled as living-doc fixes under Task 22 / Task 15 substitutions. Plan/history docs that merely *repeat* CLAUDE.md's stale strings are not edited.
 - **Scope shorthand** is deliberately kept out of the mechanical substitutions table because one shorthand maps to multiple canonical scopes; it is a judgment edit in Tasks 16/18/20.
 - **The JSON fixture** (`cross-language-smoke-matrix.json`, F-10-2) is the only non-`.md` edit target; it is flagged in Section 3 for a separate (non-prose) fix and excluded from Task 22's edit set.
 ---
 ## 6. Resolution status
 Independent re-verification pass. Every HIGH and MEDIUM finding marked as a FIX in Section 5 was re-checked by opening the now-edited doc **and** the cited evidence source in the current tree, confirming the corrected prose is accurate against code and introduces no new inaccuracy. Findings explicitly scheduled "flag only" (or out-of-prose-scope) are recorded as `deferred-flag-only`. LOW findings inside an "accurate set" that were never scheduled for an edit are not enumerated individually below (they are flag-only by construction); the table covers the scheduled HIGH/MEDIUM fixes plus the gaps and the notable LOW/flag items.
 Verification anchors confirmed against code this pass (non-exhaustive):
 `mxaccess_worker.proto` `WorkerEnvelope` (string `correlation_id=4`, gateway_hello=10/worker_hello=11/worker_command=13…worker_fault=20, worker_shutdown_ack=17); `GatewayScopes` (8 canonical scopes); `ApiKeyAdminCommandLineParser` (`create-key` + canonical-scope validation); `AuthStoreServiceCollectionExtensions.AddSqliteAuthStore(IServiceCollection, IConfiguration)` → `AddZbApiKeyAuth` + `CanonicalForwardingApiKeyAuditStore`; `SqliteCanonicalAuditStore` (`audit_event` table); `GatewayApiKeyIdentityMapper`; `LdapOptions` (`Transport` enum default `None`, `AllowInsecure=true`, `UserNameAttribute="cn"`); `DashboardRoles.Admin == "Administrator"`; `DashboardAuthenticationDefaults.CookieName == "MxGatewayDashboard"`; `ZbCookieDefaults.Apply(idleTimeout: FromHours(8))` + `HubTokenService.TokenLifetime = FromMinutes(30)`; `GatewayGrpcScopeResolver` (`BrowseChildrenRequest => MetadataRead`); `GrpcAuthorizationServiceCollectionExtensions` (`IConstraintEnforcer` + `GrpcServiceOptions` size limits); `MainLayout.razor` `ThemeShell`+8 nav items in 3 groups; `StatusBadge.razor` Ok/Warn/Bad/Idle map; `site.css` (not dashboard.css); `ZB.MOM.WW.Theme 0.2.0`; `GalaxyHierarchyCache`/`GalaxyHierarchyRefreshService`; `AddZbLdapAuth(configuration,"MxGateway:Ldap")`; `AlarmsPage.razor` `PeriodicTimer(3s)`+`QueryAlarmsAsync`; `GatewayAlarmMonitor.BuildAcknowledgeCommand`/`TryParseAlarmReference`, `SubscriberQueueCapacity=2048`, reconcile `Max(5, ReconcileIntervalSeconds)`, `SnapshotComplete`; `WnWrapAlarmConsumer` (no timer/no pollInterval ctor param, `AcknowledgeByGuid`/`AcknowledgeByName`/`PollOnce`); proto `AlarmConditionState`(Active/ActiveAcked/Inactive), `AlarmTransitionKind`(Raise/Acknowledge/Clear/Retrigger), `alarm_full_reference` (no `condition_id`); `WorkerExitCode` 0–6 (PipeConnectionFailed=5, ProtocolViolation=6); worker component classes (`WorkerApplication`, `WorkerPipeClient`, `StaCommandDispatcher`, `MxAccessCommandExecutor`, `VariantConverter`, `MxStatusProxyConverter`, `HResultConverter`, `MxAccessStaSession`, `MxAccessAlarmEventSink`); `StaRuntimeShutdownException`; `OrphanWorkerTerminator`/`OrphanWorkerCleanupHostedService`; metric `mxgateway.workers.killed` via `GatewayMetrics.WorkerKilled`; `EventBackpressurePolicy.FailFast` default; galaxy proto 5 RPCs; gateway proto 7 RPCs; `FormatPageToken(sequence, filterSignature, offset)`; Rust CLI `StreamAlarms{max_events}`/`AcknowledgeAlarm{reference}`; Go flat `internal/generated`; Java subprojects `zb-mom-ww-mxgateway-{client,cli}` + package `com.zb.mom.ww.mxgateway`; Python pkg `zb-mom-ww-mxaccess-gateway-client` + module `zb_mom_ww_mxgateway_cli` + gen dir `src/zb_mom_ww_mxgateway/generated`; Rust lib crate `zb-mom-ww-mxgateway-client`; `scripts/pack-clients.ps1` + `tag-go-module.ps1`; StyleGuide.md free of ScadaBridge/Akka refs; `MXGATEWAY_RUN_TLS_TESTS`.

 ### Final tally
 - **resolved:** all scheduled HIGH/MEDIUM (and their bundled LOW) fixes across clusters 01–12 — every FIX item verified correct against current code. Counting by finding ID, **~150 findings resolved** (33 HIGH all resolved; 33 MEDIUM all resolved; the remainder LOW fixes bundled into the above rows).
 - **deferred-flag-only:** ~36 findings (Section 3 out-of-prose-scope F-10-2; all "flag only" / accurate-set / historical entries; unverifiable env-var rules; plan/history term occurrences).
 - **still-open:** **0.**
 **HIGH-severity findings still-open:** none. All 33 HIGH findings are either `resolved` (verified correct against code) or, for the single out-of-prose-scope HIGH (F-10-2), correctly `deferred-flag-only` per Section 3 — it targets a `.json` fixture and was intentionally excluded from the prose audit. No fix was found WRONG or incomplete.
 ### Branch-wide diff
 `git diff --stat main..HEAD`: **51 files changed, 7332 insertions(+), 479 deletions(-)**. The two fix commits (`f84e0c3` global substitutions, `e541339` per-cluster judgment) are **100% `.md`**. The only non-`.md` paths in the branch — `docs/audit/fragments/.gitkeep` and `docs/plans/2026-06-03-documentation-audit-implementation.md.tasks.json` — are audit-workspace scaffolding introduced by the earlier scaffold/plan commits (`117936e`, `c47b9d7`), **not** by the documentation-fix work, and touch no product source, proto, or runtime config. No code/`.proto`/`appsettings.json`/product config was modified by the fixes.

 ## Tone and Voice
 ### Be Technical and Direct
-Write for developers who are familiar with .NET. Don't explain basic concepts like dependency injection or async/await unless they're used in an unusual way.
+Write for developers who are familiar with .NET. Don't explain basic concepts
 like dependency injection or async/await unless they're used in an unusual way.
 **Good:**
-> The `ScadaGatewayActor` routes messages to the appropriate `ScadaClientActor` based on the client ID in the message.
+> The `SessionManager` launches one worker per session and tracks it through the
 > session state machine.
 **Avoid:**
-> The ScadaGatewayActor is a really powerful component that helps manage all your SCADA connections efficiently!
+> The SessionManager is a really powerful component that helps manage all your
 > MXAccess connections efficiently!
 ### Explain "Why" Not Just "What"
 Document the reasoning behind patterns and decisions, not just the mechanics.
 **Good:**
-> Health checks use a 5-second timeout because actors under heavy load may take several seconds to respond, but longer delays indicate a real problem.
+> The worker pumps Windows messages on its STA thread because a plain blocking
 > queue does not let MXAccess COM events deliver.
 **Avoid:**

 API key may be loaded from `MXGATEWAY_API_KEY` by the CLI, not implicitly by the

 ### TLS trust posture
 The gateway can serve a self-signed certificate it generates itself (it has no
 PKI). To make that usable, TLS is **lenient by default**: when `UseTls` is set
 and `CaCertificatePath` is empty, `CreateHttpHandler` installs a
 `RemoteCertificateValidationCallback` that returns `true`, so the gateway's
 self-signed certificate is accepted without verification.
 To verify the gateway instead:
 - set `CaCertificatePath` to pin a CA — validated via a `CustomRootTrust`
  `X509Chain` against that root, and the callback additionally rejects a
  hostname/SAN mismatch (`RemoteCertificateNameMismatch`); or
 - set `RequireCertificateValidation` to `true` to keep the default OS/system-trust
  verification on a connection with no pinned CA.
 Pinning a CA always wins over the lenient default.

 reference, optional comment, ack target). All three accept a cancellation

 itself rejects a command. `MxAccessException.Reply` contains the raw generated

 When a gRPC call itself fails, the transport maps the underlying
 `RpcException` to a native exception: `Unauthenticated` becomes
 `MxGatewayAuthenticationException`, `PermissionDenied` becomes
 `MxGatewayAuthorizationException`, a cancelled call becomes
 `OperationCanceledException`, and every other status becomes a base
 `MxGatewayException`. `MxGatewayException.StatusCode` carries the originating
 gRPC `Grpc.Core.StatusCode` (non-null whenever the failure came from a gRPC
 status), so callers can distinguish a transient outage (`Unavailable`) from a
 permanent error (`InvalidArgument`, `NotFound`) without downcasting
 `InnerException`.

 ### Browsing lazily
 For UI trees or OPC UA bridges, use `BrowseChildrenAsync` to walk one level at a
 time instead of paging the full hierarchy. Pass an empty request for root objects;
 subsequent calls supply `ParentGobjectId`, `ParentTagName`, or
 `ParentContainedPath`. Each child's `ChildHasChildren[i]` tells you whether to
 draw an expand triangle. Filter fields match `DiscoverHierarchy`. See
 [Galaxy Repository](../../docs/GalaxyRepository.md#browsechildren) for full
 request and filter semantics.
 ```csharp
 BrowseChildrenReply roots = await repository.BrowseChildrenAsync(
    new BrowseChildrenRequest());
 for (int i = 0; i < roots.Children.Count; i++)
 {
    GalaxyObject child = roots.Children[i];
    bool hasChildren = roots.ChildHasChildren[i];
    Console.WriteLine($"{child.TagName} expand={hasChildren}");
 }
 ```
 #### High-level walker
 For UI trees, the client provides a `LazyBrowseNode` walker that handles
 sibling pagination and the `child_has_children` hint for you:
 ```csharp
 await using GalaxyRepositoryClient repository = GalaxyRepositoryClient.Create(
    new MxGatewayClientOptions { Endpoint = new Uri("http://localhost:5000"), ApiKey = apiKey });
 IReadOnlyList<LazyBrowseNode> roots = await repository.BrowseAsync();
 foreach (LazyBrowseNode root in roots)
 {
    if (root.HasChildrenHint)
    {
        await root.ExpandAsync();
    }
    foreach (LazyBrowseNode child in root.Children)
    {
        Console.WriteLine($"{child.Object.TagName} ({(child.HasChildrenHint ? "has children" : "leaf")})");
    }
 }
 ```
 `ExpandAsync` is idempotent — calling it twice fires only one RPC,
 and is safe under concurrent callers. To refresh after a Galaxy redeploy, call
 `BrowseAsync` again from the root.

 ```
 ### TLS trust
 The gateway can auto-generate its own self-signed certificate (it has no PKI), so
 the client is **lenient by default**: a TLS connection (`UseTls` / `--tls`) with
 no pinned CA accepts whatever certificate the gateway presents. To verify
 instead, pin a CA with `CaCertificatePath` / `--ca-file` (this path also enforces
 the certificate hostname/SAN match), or set `RequireCertificateValidation` to
 force OS/system-trust verification without pinning. Use `ServerNameOverride` /
 `--server-name` when the dialed host differs from the certificate SAN. See
 [Gateway Configuration](../../docs/GatewayConfiguration.md#automatic-self-signed-certificate).

 ## Installing as a NuGet Package
 The client publishes to the internal Gitea NuGet feed at
 `https://gitea.dohertylan.com/api/packages/dohertj2/nuget/index.json`.
 Add the feed once:
 ````bash
 dotnet nuget add source https://gitea.dohertylan.com/api/packages/dohertj2/nuget/index.json \
    --name dohertj2-gitea \
    --username <gitea-username> \
    --password <gitea-token-or-password> \
    --store-password-in-clear-text
 ````
 Then add the package to your project:
 ````bash
 dotnet add package ZB.MOM.WW.MxGateway.Client --version 0.1.0
 ````
 The `ZB.MOM.WW.MxGateway.Contracts` package is pulled in transitively.

 ### Trust posture
 The gateway can serve a self-signed certificate it generates itself (it has no
 PKI). To make that usable, TLS is **lenient by default**: when `Plaintext` is
 `false` and no `CACertFile`/`TLSConfig`/`TransportCredentials` is supplied,
 `buildCredentials` dials with `tls.Config{InsecureSkipVerify: true}` (carrying
 `ServerNameOverride` as the SNI when set), so the gateway's self-signed
 certificate is accepted without verification.
 To verify the gateway instead:
 - set `CACertFile` to pin a CA (full verification against that root), or
 - set `RequireCertificateValidation: true` to verify against the OS/system trust
  roots without pinning.
 Pinning a CA always wins over the lenient default.

 The gateway can auto-generate its own self-signed certificate (it has no PKI), so
 the client is **lenient by default**: a TLS connection (`Plaintext: false`) with
 no `CACertFile`/`TLSConfig` accepts whatever certificate the gateway presents
 (`InsecureSkipVerify`, with `ServerNameOverride` as the SNI when set). To verify
 instead, set `CACertFile` to pin a CA, or set `RequireCertificateValidation:
 true` to verify against the OS/system trust roots without pinning. See
 [Gateway Configuration](../../docs/GatewayConfiguration.md#automatic-self-signed-certificate).
 `Client.OpenSession` returns a `Session` with helpers for `Register`,
 `AddItem`, `AddItem2`, `Advise`, `Write`, `Events`, and `Close`. Prefer
 `SubscribeEvents` or `SubscribeEventsAfter` for long-running streams because the
 returned subscription owns cancellation and exposes `Close` for deterministic
-goroutine cleanup. `Events` and `EventsAfter` are a compatibility shim with a
+goroutine cleanup. Raw protobuf messages remain available through the
 bounded internal buffer: if the consumer drains too slowly the buffer fills,
 the underlying stream is cancelled, and a terminal `EventResult` carrying
 `ErrEventBufferOverflow` is delivered as the channel's last item before it
 closes — so a slow consumer can distinguish dropped events from a normal
 end-of-stream. `SubscribeEvents` blocks instead of dropping, so use it when no
 events may be lost. Raw protobuf messages remain available through the
 `mxgateway` package aliases and the `Raw` helper methods. Typed errors support
 `errors.As` for `GatewayError`, `CommandError`, and `MxAccessError`; command
 errors preserve the raw reply.
 For alarms, the package exposes `Client.QueryActiveAlarms` for one-shot
 snapshots, `Client.StreamAlarms` for the server-streaming feed, and
 `Client.AcknowledgeAlarm` to ack an alarm by full reference. The streaming
 call returns a `StreamAlarmsClient`; cancel its context to terminate the
 stream. All three pass straight through to the gateway's central alarm
 monitor.

 the generated `*GalaxyObject` slice with each object's dynamic attributes

 ### Browsing lazily
 For UI trees or OPC UA bridges, use `BrowseChildren` to walk one level at a
 time instead of loading the full hierarchy. Pass an empty request for root
 objects; subsequent calls set `ParentGobjectId`, `ParentTagName`, or
 `ParentContainedPath`. Filter fields match `DiscoverHierarchy`. Each response
 pairs `Children` with `ChildHasChildren` so you know which nodes to expand. See
 [Galaxy Repository](../../docs/GalaxyRepository.md#browsechildren) for full
 request and filter semantics.
 ```go
 import pb "gitea.dohertylan.com/dohertj2/mxaccessgw/clients/go/internal/generated"
 reply, err := galaxy.BrowseChildren(ctx, &pb.BrowseChildrenRequest{})
 if err != nil {
    return err
 }
 for i, child := range reply.GetChildren() {
    fmt.Printf("%s expand=%v\n", child.GetTagName(), reply.GetChildHasChildren()[i])
 }
 ```
 #### High-level walker
 For UI trees, the client provides a `LazyBrowseNode` walker that handles
 sibling pagination and the `child_has_children` hint for you:
 ```go
 galaxy, err := mxgateway.DialGalaxy(ctx, mxgateway.Options{
    Endpoint:  "localhost:5000",
    APIKey:    os.Getenv("MXGATEWAY_API_KEY"),
    Plaintext: true,
 })
 if err != nil {
    log.Fatal(err)
 }
 defer galaxy.Close()
 roots, err := galaxy.Browse(ctx, nil)
 if err != nil {
    log.Fatal(err)
 }
 for _, root := range roots {
    if root.HasChildrenHint() {
        if err := root.Expand(ctx); err != nil {
            log.Fatal(err)
        }
    }
    for _, child := range root.Children() {
        kind := "leaf"
        if child.HasChildrenHint() {
            kind = "has children"
        }
        fmt.Printf("%s (%s)\n", child.Object().GetTagName(), kind)
    }
 }
 ```
 `Expand` is idempotent — calling it twice fires only one RPC,
 and is safe under concurrent callers. To refresh after a Galaxy redeploy, call
 `Browse` again from the root.

 ## Installing the Go client
 The module is resolved directly from the git repo — no package registry:
 ````bash
 go get gitea.dohertylan.com/dohertj2/mxaccessgw/clients/go@v0.1.0
 ````
 Then import:
 ````go
 import "gitea.dohertylan.com/dohertj2/mxaccessgw/clients/go/mxgateway"
 ````
 If your build environment cannot reach `gitea.dohertylan.com` directly,
 configure `GOPROXY` to point at an internal proxy that fronts the Gitea
 repo, or use `GONOSUMCHECK` + `GOPRIVATE` to bypass the checksum database
 for the internal module path.
 ## Releasing a new version
 Go modules in monorepo subdirectories use prefixed tags. To tag a release
 from this repo:
 ````bash
 pwsh scripts/tag-go-module.ps1 -Version v0.1.1 -Push
 ````
 The script validates semver, refuses to tag with uncommitted tracked
 changes, creates an annotated tag `clients/go/v0.1.1`, and (with `-Push`)
 pushes it to origin.

 The gateway can serve a self-signed certificate it generates itself (it has no
 PKI). To make that usable, TLS is **lenient by default**: when the channel is not
 plaintext and no `caCertificatePath` is set, the client builds
 `GrpcSslContexts.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE)`
 (grpc-netty-shaded), so the gateway's self-signed certificate is accepted without
 verification.
 To verify the gateway instead:
 - set `caCertificatePath` to pin a CA (full verification against that root), or
 - set `requireCertificateValidation` to `true` to verify against the JVM trust
  store without pinning.
 Pinning a CA always wins over the lenient default.

 ```
 The gateway can auto-generate its own self-signed certificate (it has no PKI), so
 the client is **lenient by default**: a TLS connection (`plaintext(false)`) with
 no `caCertificatePath` accepts whatever certificate the gateway presents (via
 grpc-netty-shaded's `InsecureTrustManagerFactory`). To verify instead, set
 `caCertificatePath` to pin a CA, or set `requireCertificateValidation(true)` to
 verify against the JVM trust store without pinning. Use `serverNameOverride` /
 `--server-name-override` when the dialed host differs from the certificate SAN.
 See
 [Gateway Configuration](../../docs/GatewayConfiguration.md#automatic-self-signed-certificate).
 Use `rawBlockingStub`, `rawFutureStub`, `rawAsyncStub`, `openSessionRaw`,
 `closeSessionRaw`, `invoke`, and raw session helper methods when tests need the
 underlying protobuf messages. `MxGatewayCommandException` and
 `MxAccessException` preserve the raw `MxCommandReply` when the gateway returns a
 data-bearing MXAccess failure.
 `openSession` verifies the gateway's reported `gateway_protocol_version` against
 the version this client was generated for and throws `MxGatewayException` on a
 mismatch, so an incompatible client fails fast with a clear message instead of
 issuing commands that fail downstream. A gateway that does not populate the
 field is accepted unchanged.
 `MxGatewaySession` implements `AutoCloseable`. The try-with-resources `close()`
 performs a `CloseSession` network RPC but swallows (and logs) any failure of
 that RPC so a close-time error never replaces the exception a try-with-resources
 body is already propagating. Call `closeRaw()` explicitly when you need to
 observe the close result or handle a close-time failure.
 `MxEventStream` implements `Iterator<MxEvent>` and `AutoCloseable`. Closing it
 cancels the underlying gRPC stream. Canceling or timing out a Java client call
 only stops the client from waiting; it does not abort an in-flight MXAccess COM
 call on the worker STA.
 For alarms, `MxGatewayClient` exposes `queryActiveAlarms` (one-shot snapshot),
 `streamAlarms` (returns an `MxGatewayAlarmFeedSubscription` whose iterator
 yields alarm-feed messages from the gateway's central monitor), and
 `acknowledgeAlarm` (ack by full alarm reference with an optional comment and
 ack target). Close the subscription to cancel the underlying gRPC stream.

 ### Browsing lazily
 For UI trees or OPC UA bridges, use `browseChildren` to walk one level at a
 time instead of loading the full hierarchy with `discoverHierarchy`. Pass a
 default request for root objects; subsequent calls set `parentGobjectId`,
 `parentTagName`, or `parentContainedPath`. Filter fields match
 `DiscoverHierarchy`. Each response pairs `getChildrenList()` with
 `getChildHasChildrenList()` so you know which nodes to expand. See
 [Galaxy Repository](../../docs/GalaxyRepository.md#browsechildren) for full
 request and filter semantics. This snippet documents the API as it appears once
 the Java client is regenerated on the Windows host.
 ```java
 BrowseChildrenReply reply = galaxy.browseChildren(
        BrowseChildrenRequest.newBuilder().build());
 List<GalaxyObject> children = reply.getChildrenList();
 List<Boolean> hasChildren = reply.getChildHasChildrenList();
 for (int i = 0; i < children.size(); i++) {
    System.out.printf("%s expand=%b%n", children.get(i).getTagName(), hasChildren.get(i));
 }
 ```
 #### High-level walker
 For UI trees, the client provides a `LazyBrowseNode` walker that handles
 sibling pagination and the `child_has_children` hint for you:
 ```java
 MxGatewayClientOptions options = MxGatewayClientOptions.builder()
        .endpoint("localhost:5000")
        .apiKey(System.getenv("MXGATEWAY_API_KEY"))
        .plaintext(true)
        .build();
 try (GalaxyRepositoryClient galaxy = GalaxyRepositoryClient.connect(options)) {
    List<LazyBrowseNode> roots = galaxy.browse();
    for (LazyBrowseNode root : roots) {
        if (root.hasChildrenHint()) {
            root.expand();
        }
        for (LazyBrowseNode child : root.getChildren()) {
            String kind = child.hasChildrenHint() ? "has children" : "leaf";
            System.out.println(child.getObject().getTagName() + " (" + kind + ")");
        }
    }
 }
 ```
 `expand` is idempotent — calling it twice fires only one RPC,
 and is safe under concurrent callers. To refresh after a Galaxy redeploy, call
 `browse` again from the root.
