- Admin-010: vendor Bootstrap 5.3.3 (CSS + JS bundle + maps + provenance
README) under wwwroot/lib/bootstrap and reference local paths from
App.razor — Admin no longer pulls Bootstrap from jsDelivr.
- Admin-011: swap FleetStatusPoller's three plain dictionaries for
ConcurrentDictionary so ResetCache can't race a poll tick.
- Admin-012: drop the EquipmentId column from EquipmentCsvImporter (per
admin-ui.md — equipment id is system-derived from EquipmentUuid);
EquipmentImportBatchService and the textarea placeholder updated to
match.

- Analyzers-002: drop the three dead AlarmSurfaceInvoker entries from
the wrapper-method allow-list and from the diagnostic message.
- Analyzers-003: bail out of AnalyzeInvocation when the semantic model
is null (was previously emitting a false positive).
- Analyzers-004: resolve guarded-interface + wrapper-method symbols
once via CompilationStartAction and compare with SymbolEqualityComparer
instead of formatting fully-qualified names on every invocation.
- Analyzers-005: add regression tests for default-interface-method
reads (ReadAtTimeAsync / ReadEventsAsync on a concrete driver), with
+ without an override, and inside a CapabilityInvoker.ExecuteAsync
lambda.
- Analyzers-007: rewrite the analyzer remarks to accurately describe
the symbol-identity guarded-call detection, DIM handling, and the
wrapper-lambda match heuristic.

EnqueueAsync no longer runs COUNT(*) on every alarm; consolidate
DrainOnceAsync onto a single SqliteConnection per tick (purge, batch

- Configuration-004: NodePermissions stored as int to match the EF
HasConversion<int>() in OtOpcUaConfigDbContext.ConfigureNodeAcl.
- Configuration-005: serialise LiteDbConfigCache.PutAsync so concurrent
Put for the same (ClusterId, GenerationId) cannot duplicate rows.
- Configuration-007: rethrow OperationCanceledException from
GenerationApplier.ApplyPass when the caller's token is cancelled.
- Configuration-010: scrub secrets and drop the full exception object

- Core-004: add ConfigureAwait(false) to DriverHost.RegisterAsync /
UnregisterAsync / DisposeAsync.
- Core-008: rewrite the BuildAddressSpaceAsync XML doc to correctly name
the caller (OpcUaApplicationHost.PopulateAddressSpaces) that owns the
per-driver isolation.
- Core-009: snapshot DriverResilienceOptions once per non-idempotent write
in CapabilityInvoker.ExecuteWriteAsync.
- Core-010: switch DriverResilienceOptions.Resolve to TryGetValue with a
diagnostic error message when a tier table is missing a capability.
- Core-011: add an optional diagnostic callback to PermissionTrieBuilder
so production callers can surface scope-path mismatches.
- Core-012: correct the stale WedgeDetector ctor summary and add the
Reconnecting row to DriverHealthReport's state matrix.

Records the post-review finding discovered during browser smoke-testing: the
Admin-003 hub hardening was incomplete — the server-side Blazor HubConnection
clients had no way to authenticate, so hub negotiate 401'd and four cluster
pages threw unhandled 500s. Logged as Admin-013 (High, Error handling &
resilience), Status Resolved, fixed by commits f254539 + 8d5dbb4.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The Admin-003 fix gated every SignalR hub with [Authorize], but the server-side
Blazor HubConnection clients had no way to authenticate: the browser's HttpOnly
auth cookie is not reachable from the interactive circuit, so every hub negotiate
returned 401 and the Admin live-update feature was non-functional app-wide
(silently degraded on Hosts/ScriptLog, fatal on the cluster pages).
Introduce a token-based hub auth path:
- HubTokenService mints/validates short-lived tokens using ASP.NET Core Data
Protection (the same primitive that protects the auth cookie — no signing-key
management, no new packages). Tokens carry the user's name + roles.
- HubTokenAuthenticationHandler is a custom "HubToken" auth scheme that reads the
token from the Authorization: Bearer header (negotiate) or the access_token
query parameter (WebSocket upgrade).
- The "HubClients" authorization policy runs both the cookie and HubToken
schemes; the hub endpoints use RequireAuthorization("HubClients").
- AdminHubConnectionFactory builds hub connections with an AccessTokenProvider
that mints a fresh token for the circuit's authenticated user on every
(re)connect. All six hub-consuming pages now resolve connections through it.
Hub negotiate now returns 200 and the WebSocket upgrades (101); live updates
work. The best-effort try/catch guards added previously are kept as defence.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The Admin-003 fix gated every SignalR hub with [Authorize]/RequireAuthorization,
but the server-side HubConnection clients on ClusterDetail, AclsTab, RedundancyTab
and RoleGrants cannot forward the browser's HttpOnly auth cookie — so the hub
negotiate returns 401. Those four pages called HubConnection.StartAsync()
unguarded, so the 401 surfaced as an unhandled exception (a 500 page for the
prerendered ClusterDetail, a broken circuit for the others).
Wrap StartAsync/SendAsync in try/catch on all four, matching the established
best-effort pattern already used in Hosts.razor and ScriptLog.razor: the live
banner / live refresh degrades but the page renders. Restoring functional hub
live-updates needs a token-based hub auth scheme (cookie forwarding is not
viable across the prerender/interactive boundary) and is left as follow-up.

All Medium-severity code-review findings across the 29 reviewed modules
are now Resolved. The Pending findings table holds only Low-severity items.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Core-002 fixed TriePermissionEvaluator to evaluate each request against
the session's bound AuthGenerationId rather than whatever the cache
currently holds. AuthorizationGate.BuildSessionState was not updated at
the same time: it hardcoded AuthGenerationId = 0, so the evaluator's
GetTrie(cluster, 0) call returned null for any generation != 0, causing
every gated operation to silently fail with NotGranted regardless of
actual grants. The 42 gate/matrix/deferred-hardening tests all started
failing as a result.
Fix: add an optional PermissionTrieCache parameter to AuthorizationGate;
BuildSessionState now stamps AuthGenerationId from the cache's current
generation for the session's cluster. AuthorizationBootstrap.BuildGateAsync
passes the cache it creates. All 7 test MakeGate helpers updated to pass
the cache so tests produce a valid AuthGenerationId. 433/433 server tests
now pass.

The Driver.TwinCAT-011 fix rewrote TwinCATStatusMapper with correct
numeric values from Beckhoff.TwinCAT.Ads 7.0.172 (e.g. DeviceSymbol-
VersionInvalid = 1809 / 0x0711, not 1794 / 0x0702). Pre-existing
StatusMapper_covers_known_ads_error_codes InlineData cases were written
against the old wrong mappings and now fail; StatusMapper_recognises_
symbol_version_changed_code asserted the legacy 0x0702 constant. Update
both test files to match the corrected mapper and add a comment

Trim the --type help text on read and subscribe to the implemented set

Add S7TypeMappingTests.cs covering ReinterpretRawValue and BoxValueForWrite —
26 tests verifying every implemented type round-trip (Bool/Byte/UInt16/Int16/
UInt32/Int32/Float32), two's-complement reinterpret semantics (ushort→short,

swallowed poll-loop exceptions, so operators have an event trail via Serilog.
S7-008: restructure WriteAsync catch ladder to mirror ReadAsync — OperationCanceledException
re-throws, NotSupportedException → BadNotSupported, PUT/GET-disabled PlcException →
BadNotSupported/Faulted, genuine PlcException → BadDeviceFailure/Degraded, all

Remove the dead ProbeAddress config surface from S7ProbeOptions and the factory
DTO. ProbeLoopAsync uses Plc.ReadStatusAsync (CPU-status PDU), not a tag-address
