fix(browse): commit the browsed data type, and fix the probe classification the fixture was hiding (#536)
A browse-committed AB CIP / TwinCAT / FOCAS tag bound with its model's DEFAULT
data type, not the one the device reported. A browsed REAL committed as
`{"tagPath":"Pump_1_Speed","dataType":"DInt"}` — and those three drivers decode
the wire bytes by that field, not by the raw row's OPC UA DataType — so the tag
read four bytes of a float through an integer decoder and published a plausible
wrong number with no error raised anywhere. FOCAS was missed when #536 was filed.
The type is CARRIED, not derived. Reverse-mapping the leaf's driver-agnostic
DriverDataType looks like the smaller fix and is wrong: SInt/Int/DInt/USInt/UInt
all collapse into Int32 on the way out of the driver, so that version would bind
a 16-bit INT as a 32-bit DINT while appearing to fix the REAL. Drivers now state
their own type name on DriverAttributeInfo.NativeDataType, which reaches the
picker as AttributeInfo.AddressFields["dataType"] and the commit mapper from
there. A leaf that states nothing keeps the model default — the pre-#536
behaviour, kept deliberately as the fallback rather than a guess.
Numeric strings are refused before parsing: Enum.TryParse accepts "9" for any
enum and Enum.IsDefined then confirms it, so an unguarded parse would bind a tag
to a type nobody named. A test caught this in the first version of the guard.
--- and the other half, which the fixture was hiding ---
Test Connect on a device with NO authored tags — every AB CIP device at the
moment an operator first presses the button — reported "CIP handshake failed"
against a healthy controller. That was written down as a fixture limitation
("ab_server doesn't implement @raw_cpu_type"). Both halves of that were wrong:
* @raw_cpu_type is not a libplctag special tag at all (only @raw, @tags and
@udt/ are), so it goes out as an ordinary symbolic name that no controller
defines, and the controller's "tag does not exist" IS the successful answer.
* ab_server answered an unresolvable tag path with CIP 0x03 where a Logix
controller answers 0x04 — ErrorBadParam vs ErrorNotFound, which the probe
classifies oppositely. Fixed in vendored patch 0002.
* With the fixture then telling the truth, the real defect surfaced:
AbCipDriverProbe.IsReachableException matched the native C status spellings
("STATUS_NOT_FOUND"), but libplctag.NET throws with the MANAGED enum name
("ErrorNotFound"). Those substrings can never match, so the reachable
classification could not fire on the exception path — which is the path every
no-authored-tags probe takes. This was failing on real hardware too, not just
against the sim. It now recovers the Status and defers to IsReachableStatus,
so there is one classification rather than two that can drift.
Rejected: switching the fallback to @tags. libplctag builds a tag-listing tag
with NO network I/O, so it reports OK against any TCP listener — measured green
against a Mosquitto broker.
Verification: full solution suite green. Falsification runs confirm exactly the
intended tests go red — 9 for the type carry, 3 (the reachable statuses only) for
the probe classification. Live on docker-dev: browse-committed TestString/
Motor_Run/TestSINT now store String/Bool/SInt, alongside last session's
Pump_1_Speed still holding the wrong DInt. TestSINT is the falsifier — its row
DataType is Int32, identical to TestDINT's, so no reverse map could have produced
"SInt".
Known consequence: pre-existing browse-committed tags keep their wrong dataType;
the fix applies to new commits only.

fix(mqtt): close #509, #510, #512, #513, #514
Five MQTT tracker items — four AdminUI/authoring defects plus the .Browser layering exception. No runtime driver behaviour changes. #513 payloadFormat in a Sparkplug blob. MqttTagConfigModel.ToJson wrote the key unconditionally. Sharper than the issue states: PayloadFormat is the one Plain field with a NON-NULLABLE typed backing, so the write did not preserve a retyped tag's leftover — it INVENTED "payloadFormat":"Json" in a Sparkplug tag that never had one. Now Plain-only; preserve-unknown-keys is pinned unchanged. #509 slashed Sparkplug metric names. The mapper already carried metricName verbatim; only the tag Name (a RawPath segment) tripped RawPaths.ValidateSegment, which refused the batch whole — including Node Control/Rebirth, mandatory on every Sparkplug edge node. ToRawSegment coerces the Name and leaves the address untouched. Coercion is not injective, so DescribeNameCollisions refuses a colliding set BY NAME: silently merging two metrics into one tag would be worse than the refusal it replaces. Applies to every driver, not just MQTT — the argument is about what a Name is, not about who produced it. The sanitiser is pinned against RawPaths.ValidateSegment rather than a copied charset. #510 stale rebirth affordance. _canRebirth was probed once at browse-open and sessions are reaped for idleness, so a modal left open offered an action whose token no longer resolved. Re-probed on arm AND on confirm (the reap can land between the two, and confirm is the one path that publishes to a live broker); the affordance retires with an explanation instead of vanishing or erroring. #514 rebirth on a quiet plant. The tree is birth-driven and births are never retained, so a plant that birthed before the window opened showed an empty tree — and the scope came only from a tree selection, so the one action that would fill the tree could not be armed. The session already accepted a bare {group}/{edgeNode} ("the prime rebirth target"); this adds the affordance. Edge-node scope only, not a group broadcast. The rule is extracted to SparkplugRebirthScope so it is testable — this repo has no bUnit — and is advisory: the session re-resolves and refuses before publishing. #512 .Browser -> .Driver layering. TWO extractions were needed, not the one the issue anticipated: it costed this as "the client-options builder", but the browse session decodes births itself, so moving only that would have left the reference exactly where it was. - MqttClientOptionsFactory (TLS, PEM CA-pin validator, credentials, protocol mapping) -> new leaf .Transport project. NOT .Contracts: that is deliberately transport-free and MqttClientOptions is an MQTTnet type, so .Contracts would hand MQTTnet to ControlPlane. This is the fix the .Browser csproj comment had already prescribed, against the issue's suggestion. - The Sparkplug protocol layer (SparkplugTopic/MessageType, SparkplugCodec, RebirthRequester) -> .Contracts, beside the Tahu wire schema it encodes. Still exactly one copy of the TLS/CA-pin logic; MqttBrowserLayeringTests guards the graph both ways. Measured, not assumed: Driver.Mqtt.dll, Polly.Core and Serilog are now absent from the AdminUI's output. Core.dll remains, because Driver.Sql.Browser has the SAME violation, undocumented — the old comment blamed this browser for Core and was wrong. Filed separately rather than fixed in passing. Full suite green apart from the 7 known pre-existing failures (4 AbLegacy integration, compose profiles not up; 3 Host.IntegrationTests).

fix(mqtt): browse-commit writes a bindable address + a Request-rebirth affordance
Two gaps the Task 23/24 review found, both blocking Task 26's live gate.
Gap 1 — browse-commit produced a silently dead MQTT tag. RawBrowseCommitMapper
had no `Mqtt` case, so a committed leaf fell through to the generic
`{"address": …}` key. Neither MqttTagDefinitionFactory entry point reads
`address`: the tag deployed clean and reported BadNodeIdUnknown forever, with
no signal at commit time. Predates Task 23 (Plain was affected too), but Task 23
built the Sparkplug metric tree precisely so an operator could browse and commit
a binding.
The address is a DESCRIPTOR, not a reference string, and it cannot be recovered
from the browse node id: `{group}/{node}[/{device}]::{metric}` where a metric
name legitimately contains `/` (`Node Control/Rebirth`) — the ambiguity
MetricSeparator's remarks already name. So the session STATES it, via a new
`AttributeInfo.AddressFields` seam, and the mapper reads it. Which keys are
emitted is also how the mapper learns Plain vs Sparkplug — the driver type
reaching it is just `Mqtt`, and the mode lives on the driver config. Key names
are single-sourced in the new `MqttTagConfigKeys` (producer, mapper, factory),
with the literals pinned by a test so a symmetric rename cannot silently unbind
already-persisted blobs. A leaf with no stated address is refused at commit in
words rather than committed dead.
Gap 2 — RequestRebirthAsync had no UI. Task 23 shipped it backend-only; Task 26
step 1 assumes the button, and Task 25's runbook notes the picker tree stays
empty until a birth lands, so it is the only way to fill it on demand. Added to
the /raw browse modal: scope = the clicked tree node (device/metric resolve up to
their edge node, group fans out and is refused whole past 32), an explicit
two-click confirm naming the resolved scope and its consequence, the outcome or
the refusal shown rather than swallowed. Offered only for a Sparkplug session
(new `IRebirthCapableBrowseSession.RebirthAvailable` — one session class serves
both modes, so a type test alone would draw a button that can only throw) and
only to a DriverOperator; the server-side gate remains the boundary.
Tests: MQTT 545 → 581, AdminUI 781 → 800. The round-trip tests feed the emitted
blob to the REAL factory and were falsified by mutating the emitted key name.

feat(adminui): B2-WP6 browse re-target — /raw device browse commits raw tags
Browse device… on a /raw Device/TagGroup opens the discovery-browser modal against the merged Driver+Device config and commits selected browse leaves as raw Tag rows under the target, via IRawTreeService.ImportTagsAsync. - RawBrowseModal.razor: two-tier browse gate (bespoke IDriverBrowser → universal DiscoveryDriverBrowser via SupportsOnlineDiscovery → disabled), merged config from LoadMergedProbeConfigAsync, multi-select over DriverBrowseTree, opt-in 'create matching tag-groups' folder mirror, commit via ImportTagsAsync. - RawBrowseCommitMapper: pure leaf→RawTagImportRow mapper — DriverDataType→ OPC UA type, per-driver address field (nodeId/tagPath/symbolPath/address/ attributeRef), target-group + mirror path combine. Unit-tested (39 tests). - DriverBrowseTree: additive multi-select mode (checkboxes + ancestor-path callback), default off preserves single-select pickers. - RawTree: OnBrowseDevice wired to the modal (Device + TagGroup menus).
