60366b72c6 fix(scripting): resolve Medium code-review finding (Core.Scripting-003)
Add System.Threading.Tasks to ForbiddenNamespacePrefixes so scripts
cannot use Task.Run / Parallel to spawn background work that outlives
the per-evaluation timeout. Document the unbounded-memory accepted
trade-off and the Task denial rationale in docs/VirtualTags.md (new
"Known resource limits" subsection) and cross-reference from
docs/ScriptedAlarms.md.

02daacbfd0 fix(driver-historian-wonderware): resolve Medium code-review finding (Driver.Historian.Wonderware-003)
Extract the string-vs-numeric value selection from raw and at-time read
loops into a SelectValue helper method. aahClientManaged's HistoryQueryResult
has no data-type field in the bound SDK version, so the heuristic (prefer
StringValue when non-empty and Value==0) is unavoidable; the helper now
documents the limitation explicitly in its XML doc so the known edge case
(numeric tag at exactly zero with a formatted StringValue) is self-evident.

37945deb0a fix(driver-abcip): resolve Medium code-review finding (Driver.AbCip-006)
`PlcTagHandle` and `DeviceState.TagHandles` were dead scaffolding: the
`ReleaseHandle` no-op never called `plc_tag_destroy` and the dict was
never populated. Removed the file, the dead dict, and its
`DisposeHandles` loop. Updated the `AbCipDriver` class doc to document
that native lifetime is owned by libplctag.NET `Tag.Dispose()` (invoked
from `DisposeHandles`) with the library's own finalizer covering any
GC-collected instances. Two test methods that only exercised the dead
`PlcTagHandle` class removed from `AbCipDriverTests`.

205b07f6aa fix(driver-historian-wonderware): resolve Medium code-review finding (Driver.Historian.Wonderware-002)
Normalise req.Events to Array.Empty<AlarmHistorianEventDto>() immediately
after MessagePack deserialization in HandleWriteAlarmEventsAsync. MessagePack
deserializes an absent or explicit-nil array field as null, not Array.Empty,
so a peer that sends a null Events array would trigger a NullReferenceException
on either .Length dereference (no-writer branch or catch block), leaving the
client correlation-id wait hanging with no reply frame.

Document explicitly that WriteBatchAsync never returns PermanentFail because
the WriteAlarmEventsReply wire contract carries only a bool-per-event (no
unrecoverable/transient distinction). Add a <remarks> XML block explaining
the structural limitation, why poison events retry rather than dead-letter,
and that a coordinated per-event status enum extension to the .NET 4.8
sidecar is a tracked follow-up. Add inline NOTE comments in both the
success and catch paths for discoverability.

5bcbda1685 fix(driver-historian-wonderware-client): resolve Medium code-review finding (Driver.Historian.Wonderware.Client-007)
Introduce DeserializeSampleValue() helper that enforces a 64 KiB per-sample
ValueBytes size cap before calling MessagePackSerializer.Deserialize<object>,
and documents that the default StandardResolver (primitive-only, no typeless
or dynamic-type resolution) is in use. Both ToSnapshots and AlignAtTimeSnapshots
route through the new helper. Add inline XML comments to the two NuGetAuditSuppress
entries in the csproj recording the advisory title, why each does not apply to
this module's primitive-only deserialization, and when to revisit.

d5b8c802ce fix(driver-abcip): resolve Medium code-review finding (Driver.AbCip-005)
Structure tags with declared Members no longer register the bare parent
name in `_tagsByName` — reading it would return Good/null, which is
misleading. Clients read individual member paths. Both the member
fan-out and the scalar-tag paths now perform a duplicate-key check that
throws `InvalidOperationException` naming both colliding entries (fail-
fast, consistent with the AbCipHostAddress validation pattern).

1722c0328b fix(driver-abcip): resolve Medium code-review finding (Driver.AbCip-004)
`ToDriverDataType` mapped LInt/ULInt to Int32 (truncation) and UDInt
to Int32 (negative wrap for values > Int32.MaxValue). DriverDataType
already carries Int64/UInt64/UInt32, so map each Logix 64-bit and
unsigned-32-bit type to the correct member. `DecodeValueAt` in
`LibplctagTagRuntime` updated to return uint/ulong for UDInt/ULInt
so the runtime value type agrees with the declared OPC UA type.

e8edf123ff fix(driver-cli-common): resolve Medium code-review finding (Driver.Cli.Common-005)
Added missing test coverage identified in the -005 finding:

- FormatTable_with_empty_input_returns_header_only: verifies the -004 fix
  (empty batch read returns header+separator rather than throwing).
- FormatStatus_with_sub_code_bits_resolves_to_named_class: Theory exercising
  the -002 high-word mask path (e.g. 0x80050001 → "BadCommunicationError").
- FormatStatus_unknown_sub_code_falls_back_to_severity_class: Theory for the
  -002 severity-class fallback (unknown sub-codes still emit Good/Uncertain/Bad).
- New DriverCommandBaseTests class: four tests covering verbose/non-verbose
  Serilog level selection, ConfigureLogging idempotency, and FlushLogging.

Also corrected the stale FormatStatus_unknown_codes_fall_back_to_hex_only
expectation (0xDEADBEEF now resolves to "Bad" via the severity-class fallback
introduced by -002, not bare hex) and fixed the FormatTable empty-input crash
(guard rows.Length == 0 before calling Enumerable.Max).

7ff356bddc fix(driver-cli-common): resolve Medium code-review finding (Driver.Cli.Common-003)
ConfigureLogging is now idempotent via a _loggingConfigured guard field so
repeated calls from subclasses do not abandon and leak the previous logger.
The previous Log.Logger is disposed before overwriting to release its
console-sink resources cleanly.

A new protected static FlushLogging() helper calls Log.CloseAndFlush() so
commands can guarantee buffered output is flushed in their finally blocks
before the process exits — important for the long-running subscribe verb.

XML doc updated to reflect call-once semantics and document FlushLogging().

1433a1cf30 fix(driver-cli-common): resolve Medium code-review finding (Driver.Cli.Common-002)
FormatStatus now matches named codes against code & 0xFFFF0000 (high-word
mask) rather than exact equality, so status codes carrying sub-code or flag
bits in the low 16 bits (e.g. 0x80050001) still resolve to their named class.
For codes not in the named shortlist a severity-class fallback using the top
2 bits always emits Good / Uncertain / Bad rather than bare hex.

Updated the stale FormatStatus_unknown_codes_fall_back_to_hex_only test (its
expectation became invalid once the severity-class fallback was added) and
added new Theory cases exercising both the high-word matching and the
severity-class fallback paths.

69994f9cf6 fix(scripted-alarms): resolve Medium code-review finding (Core.ScriptedAlarms-012)
Add engine-level tests covering the six gaps identified in the finding:
(1) timed-shelve auto-expiry driven via injectable clock + RunShelvingCheckForTest
    hook so timer tests are deterministic;
(2) ConfirmAsync, TimedShelveAsync/UnshelveAsync round-trip, EnableAsync engine
    methods exercised end-to-end;
(3) OnEvent subscriber-throws isolation — engine state advances and stays
    operational after a subscriber throws;
(4) IAlarmStateStore.SaveAsync failure leaves in-memory state unchanged (locks in
    the persist-before-update invariant from finding-007);
(5) second LoadAsync does not leak the old timer (regression for finding-002);
(6) AreInputsReady cold-start guard correctly blocks on Bad/missing inputs and
    allows Uncertain-quality inputs through.

Expose RunShelvingCheckForTest() internal method on ScriptedAlarmEngine to
support deterministic timer tests.

SubscribeAsync now wraps each driver handle in a private HostBoundHandle
that carries the resolved host name.  UnsubscribeAsync unwraps it and
routes through the recorded host's resilience pipeline, correctly
charging the subscription's originating host's circuit breaker/bulkhead
instead of always using the default host.  Falls back to the default
host for handles not created by this invoker.  Two regression tests
added; update findings.md Open count from 10 to 6.

added: double-build does not double-fire, sink count is correct after
rebuild, and post-dispose call throws.

Reorder persist/update in ApplyAsync, ReevaluateAsync, and ShelvingCheckAsync:
SaveAsync is now called before the in-memory _alarms entry is advanced. A store
failure therefore leaves both the persisted and in-memory views at the prior state
rather than diverging, maintaining the invariant that startup recovery reflects
actual persisted state.

cdaa0da45d fix(scripted-alarms): resolve Medium code-review finding (Core.ScriptedAlarms-005)
Add _disposed re-checks inside ReevaluateAsync and ShelvingCheckAsync after
acquiring _evalGate so callbacks in flight when Dispose() runs bail out cleanly
instead of mutating _alarms or writing to a disposed store. Drop the
_alarms.Clear() from Dispose() — clearing outside the gate races concurrent
reads and is unnecessary since the object is being discarded.

Split the LoadAsync seed-read + subscribe loop: ReadTag seed fills _valueCache
first, then persisted-state restore runs, then _loaded = true, then SubscribeTag
is called. Any synchronous initial push from the upstream now arrives after
_alarms is fully initialised and _loaded = true, so ReevaluateAsync will queue
correctly behind the gate rather than racing the half-built state.

a0aa4a4819 fix(admin): complete Admin-006 — inject IAntiforgery into LogoutAsync for explicit token validation
The previous Admin-006 commit added <AntiforgeryToken /> to the logout form
and updated the comment on the endpoint, but did not update LogoutAsync to
actually call IAntiforgery.ValidateRequestAsync. Blazor's UseAntiforgery()
middleware does not automatically validate minimal-API endpoints, so a
tokenless POST still succeeded. This commit injects IAntiforgery into the
handler, wraps ValidateRequestAsync in a try/catch, and returns 400 on
AntiforgeryValidationException. The endpoint keeps .DisableAntiforgery() to
prevent the middleware from also trying to read the body (which would cause
a double-read). The regression test is updated to log in first (to get an
authenticated session) before asserting 400 on a tokenless logout POST.

validates the token. A tokenless POST now returns 400, preventing CSRF-logout.
Regression-guarded by AuthEndpointsTests.Logout_without_antiforgery_token_is_rejected.

55c2a5a209 fix(client-ui): resolve Medium code-review finding (Client.UI-002)
Guard the two nullable child VM dereferences (BrowseTree at ConnectAsync
and History at ViewHistoryForSelectedNode) with != null checks, matching
the guarding style already used for Subscriptions and Alarms nearby.

2816c76c2b fix(client-ui): resolve Medium code-review finding (Client.UI-001)
Route the synchronous IsLoading = true write through _dispatcher.Post so
both IsLoading assignments use the same dispatch path as Results.Clear()
and the final IsLoading = false, eliminating the ordering hazard.

40f06314fb test(virtual-tags): unbreak script-timeout test after sandbox deny-list change
The Timeout_maps_to_BadInternalError_without_killing_the_engine test's
"Hang" script busy-looped on Environment.TickCount64. Commit cfb9ff1
(Core.Scripting-001) added System.Environment to the script-sandbox
deny-list, so the script now fails sandbox validation instead of
reaching the timeout path. Switch the busy-loop to DateTime.UtcNow
(an allowed type) to preserve the test's intent — a self-terminating
~5s hang that overruns the 30ms script timeout.

5499b817c8 fix(driver-historian-wonderware-client): resolve High code-review finding (Driver.Historian.Wonderware.Client-001)
WonderwareHistorianClient.ReadAtTimeAsync passed the sidecar's reply.Samples
straight through ToSnapshots, which violated the IHistorianDataSource
contract: the result MUST be the same length and order as the requested
timestampsUtc, with gaps returned as Bad-quality snapshots. If the sidecar
dropped or reordered samples, OPC UA HistoryReadAtTime would silently
misalign values with timestamps.

Add an AlignAtTimeSnapshots helper that indexes the returned samples by
timestamp ticks, builds the result array at timestampsUtc.Count in request
order, and emits a Bad-quality (0x80000000) snapshot for any requested
timestamp the sidecar did not return.

Add the ReadAtTimeAsync_PartialAndReorderedReply_AlignsByTimestamp_AndFillsGapsAsBad
regression test where the fake returns a partial, reordered sample set.

Update code-reviews/Driver.Historian.Wonderware.Client/findings.md: -001
Resolved, open-finding count 10 -> 9.

f982fa1f69 fix(driver-historian-wonderware): resolve High code-review finding (Driver.Historian.Wonderware-001)
WriteToReadOnlyFile was listed in MalformedErrors, so ClassifyOutcome/
MapOutcome routed it to PermanentFail and the store-and-forward sink
dead-lettered every alarm event in the batch. But WriteToReadOnlyFile is
a connection-configuration fault (the write session was opened without
ReadOnly = false), not an event-payload fault — treating it as permanent
silently and permanently discards alarm events on a misconfigured or
regressed connection, which is data loss.

Move WriteToReadOnlyFile from MalformedErrors into ConnectionErrors. The
batch loop now aborts the batch, resets the connection (so the reconnect
path re-opens a writable ReadOnly = false session), and defers the
events as RetryPlease for the next drain tick.

Updated the ClassifyOutcome theory data and added a dedicated regression
test pinning WriteToReadOnlyFile -> RetryPlease.

1837b5a828 fix(driver-modbus-addressing): resolve High code-review finding (Driver.Modbus.Addressing-001)
The DL205 family-native branch routed every V-prefixed address through
DirectLogicAddress.UserVMemoryToPdu, a plain octal-to-decimal decode.
DL205/DL260 system V-memory (V40400 and up) is not a simple octal decode:
the CPU relocates the system bank to Modbus PDU 0x2100. Octal-decoding
V40400 produced 16640 (0x4100), the wrong register, so any tag addressing
a system register through the grammar string silently read/wrote the
wrong PLC memory.

- Add DirectLogicAddress.VMemoryToPdu, which decodes the octal V-address,
  detects the system bank (octal >= V40400 == SystemVMemoryOctalBase) and
  relocates it through SystemVMemoryToPdu to PDU 0x2100; user-bank
  addresses keep the plain octal decode.
- ModbusAddressParser's DL205 V branch now calls VMemoryToPdu instead of
  UserVMemoryToPdu. UserVMemoryToPdu is retained for user-bank-only callers.
- Correct the ModbusFamilyParserTests V40400 assertion (16640 -> 0x2100)
  and add system-bank regression cases plus direct helper coverage.

532b961cf2 fix(driver-modbus): resolve High code-review finding (Driver.Modbus-001)
_lastPublishedByRef was a plain Dictionary<string, object> mutated inside
ShouldPublish, which runs on the PollGroupEngine onChange callback. The engine
runs one background Task per subscription, so a driver with two or more
subscriptions invokes ShouldPublish concurrently on separate threads. Concurrent
TryGetValue/indexer writes on a non-thread-safe Dictionary can corrupt internal
state, drop entries, or throw, crashing the poll loop.

Switch _lastPublishedByRef to ConcurrentDictionary<string, object>; its
TryGetValue and indexer-set operations are individually thread-safe, so the
deadband cache is now correct under concurrent multi-subscription publishing,
consistent with the lock-guarded sibling cache _lastWrittenByRef.

Add an xUnit + Shouldly regression test that runs 24 deadband-configured
single-tag subscriptions concurrently and asserts the poll loop survives without
faulting.

7f2e144f8d fix(driver-galaxy): resolve High code-review findings (Driver.Galaxy-002, Driver.Galaxy-008)
Driver.Galaxy-002 — DataTypeMap.Map had no Int64 arm though MxValueDecoder/
MxValueEncoder both fully support Int64. Galaxy attributes with the Int64
mx_data_type code fell through to the String default, creating a String
address-space node while runtime reads decoded a boxed long. Added
`6 => DriverDataType.Int64`, extending the contiguous 0..5 scheme so the type
map agrees with the decoder/encoder on all seven Galaxy data types.

Driver.Galaxy-008 — after a stream fault the EventPump's StreamEvents consumer
loop exited and its channel completed; EventPump.Start() is a no-op on a
completed-but-non-null loop, so a replayed subscription had no consumer and
ReplayAsync never re-registered the post-reconnect item handles. ReplayAsync
now recreates the EventPump (RestartEventPumpForReplay) and rebinds the
SubscriptionRegistry per subscription with the fresh item handles returned by
the post-reconnect SubscribeBulkAsync, via new SubscriptionRegistry.SnapshotEntries
and Rebind APIs.

Regression tests: DataTypeMapTests (every code incl. Int64), SubscriptionRegistry
Tests (Rebind/SnapshotEntries), EventPumpStreamFaultTests (faulted pump dead,
fresh pump resumes dispatch).
