The P1 live gate had to insert MQTT driver config directly via SQL: DriverConfigModal and
DeviceModal both fell through to "No typed config form for driver type Mqtt" with no raw-JSON
fallback, so broker host/port/TLS/credentials were unauthorable from the AdminUI. Task 12 built
the *tag* editor; these are the driver + device surfaces.
MqttDriverForm authors the whole MqttDriverOptions connection surface (host/port/clientId,
TLS + CA pin, credentials, protocol version/clean-session/keep-alive, connect timeout, reconnect
backoffs, mode, maxPayloadBytes, and the Plain sub-object). The Sparkplug sub-object stays P2 —
a marked placeholder mirroring MqttTagConfigEditor's stub, with any existing sparkplug keys
preserved untouched.
The connection is authored on the DRIVER, not the device — unlike Modbus/S7/OpcUaClient and
contrary to what docs/drivers/Mqtt.md said. DriverDeviceConfigMerger merges a device's keys up
only when the driver has exactly ONE device, so a device-authored broker connection vanishes
silently the moment a second device is added. MqttDeviceForm is therefore informational (the
GalaxyDeviceForm shape) and round-trips DeviceConfig verbatim; it flags legacy connection keys
left on a device by a pre-form deployment, because those still win via merge-up.
Serialization goes through the ONE shared MqttJson.Options instance (Task 9's decision), never a
fifth per-form copy — pinned by an assertion that an ordinal-only reader CANNOT bind the emitted
blob, and by extending the fleet-wide DriverPageJsonConverterTests guard to resolve a form's
serializer from an explicit external-instance registry when it has no _jsonOpts field. Dropping
the converter from MqttJson.Options reddens 3 tests and leaves the symmetric round-trip green —
the Task 9 lesson, reproduced.
RawTags is stripped from the emitted blob (the deploy artifact owns it) and unknown top-level
keys survive a load->save. Validation mirrors the driver's own [Range] bounds inline, and
ToOptions() additionally clamps, so an ignored error still cannot persist a
connectTimeoutSeconds:0 driver-brick. A non-blank clientId raises the P1 live-gate warning
inline (fixed ids make redundant pair nodes evict each other while both report Healthy).
AdminUI 761/761 green (was 730), TWAE-clean; Driver.Mqtt 266/266 green.

Task 14 — the P1 milestone gate. Ran the live /run verification on a docker-dev
rig against the real Mosquitto TLS+auth fixture, and recorded the result.
The gate did its job: it found MQTT was unauthorable in production.
RawDriverTypeDialog's driver-type list is a hand-maintained array that nobody
added MQTT to, so the /raw "New driver" picker never offered it — with every
other layer (contracts, driver, browser, factory, host registration, typed tag
editor) complete and 266 green unit tests. Nothing tied that array to
DriverTypeNames and AdminUI has no bUnit, so no offline test could see it.
Fixed, plus RawDriverTypeDialogParityTests: a reflection parity guard that
fails for ANY DriverTypeNames entry missing from the picker. Verified
falsifiable — RED with "…cannot be authored from the /raw New-driver picker,
so they are unreachable in production: Mqtt" before the one-line fix.
A second gap is left OPEN and documented, not fixed (no task ever covered it):
MqttDriverForm / MqttDeviceForm do not exist, and DriverConfigModal/DeviceModal
have no raw-JSON fallback — so an operator can create an MQTT driver but cannot
author its broker endpoint or credentials. P1 is not operator-complete until
those two razor forms land. The gate authored config via SQL to get past it.
Live gate result (isolated 2-node MAIN stack, image built from this branch,
fixture at 10.100.0.35:8883, AllowUntrustedServerCertificate rather than
pinning the CA into the rig):
- typed MQTT tag editor renders and round-trips; Json shows the JSON-path
field, Raw/Scalar hide it; wildcard topic a/+/c blocked at save; data-type
list offers Float64 and no Double; qos/retainSeed absent on "(driver
default)" and qos:2 written as a number; isHistorized/historianTagname
survive a topic-only edit; SparkplugB renders the P2 placeholder and
switching back keeps Plain values; jsonPath is guidance not a gate in all
three shapes ($ seeded only for a brand-new blank tag, blank stays absent,
clearing saves fine)
- deployed, and both editor-written blobs resolved and served changing live
values through OPC UA (22.8 / 1629, StatusCode Good) — no BadNodeIdUnknown
- the bespoke #-observation browser drove a real broker session and rendered
the fixture's actual topic tree (line1/{counter,state,temperature},
noise/chatter, retained/seed); a Modbus device's picker still correctly
reports "Browsing unavailable"
Also found live and documented (not a code change): both nodes of a redundant
pair run the driver, so a FIXED clientId makes them evict each other forever —
the broker logs "already connected, closing old connection" and both nodes
reconnect every ~2s while still reporting Healthy. Unset (the default) is
correct; confirmed 0 reconnects/60s on both nodes after removing it.
Suites: offline 1134 passed / 0 failed (266 Driver.Mqtt + 730 AdminUI incl. the
3 new guards + 138 Core.Abstractions); live 7/7 against the fixture.
Docs: new docs/drivers/Mqtt.md + Mqtt-Test-Fixture.md (the per-driver + fixture
convention every other driver follows), MQTT rows in docs/drivers/README.md,
TestConnectProbes.md, root README.md, and infra/README.md §3.
CLAUDE.md drift corrected while adding the MQTT endpoints:
- the "every fixture carries project: lmxopcua" claim was false — only the
MQTT fixture does; the filter returns one stack, not the fleet
- lmxopcua-fix.ps1 is Windows-VM-only; on macOS drive the host over ssh/rsync
(and the docker-dev rig itself runs locally under OrbStack)

Review follow-up. Dropped the hard Validate rejection of a blank jsonPath under
a Json payload: the runtime defaults it to the document root, which is the real
"publisher puts a bare JSON scalar on the topic" case, so rejecting it made the
editor refuse what the driver accepts — inverting "authoring surface accepts <=>
publish accepts" — and blocked whole CSV-import batches, since this validator
also gates RawManualTagEntryModal's review grid.
Replaced with guidance: an UNAUTHORED tag (no topic AND no jsonPath) seeds the
field with "$", so a fresh tag emits an explicit "jsonPath":"$" while an
existing path-less tag keeps the key ABSENT and the driver defaults it. The
wildcard-topic rule stays strict — a wildcard has no legitimate single-Tag
interpretation.
Also: omit a blank "topic" rather than writing "topic":"", and record why the
_lastConfigJson guard diverges from the Modbus template — the landmine is a
DERIVED, NON-PERSISTED UI FIELD INFERRED FROM BLOB CONTENT (Mode), which Task
24's Sparkplug field group will be tempted to add more of. Named the host-side
dependency (RawTagModal only mutates through this callback) that keeps the
staleness trade benign today.

Thin typed model over a preserved JsonObject key bag, mirroring the sibling
<Driver>TagConfigModel template. Key names and strictness rules mirror
MqttTagDefinitionFactory rather than inventing an editor-side schema; enums
round-trip as NAMES (the factory reads them strictly by name).
No FullName key: under v3 a tag is identified by its RawPath, which the factory
keys the definition's Name off — a composed identity key here would be dead
weight nothing reads.
Mode is a UI-only sub-shape selector inferred from the blob (any Sparkplug
descriptor key present) and never serialised — the driver takes Plain vs
SparkplugB from its DRIVER config. Only Plain Validate() is implemented; the
Sparkplug branch is a stub Task 24 fills, and its keys are preserved untouched.

The Phase 3 live gate deadlocked every FetchAndCache deploy: DeploymentArtifactGrpcService
gated on Status==Sealed, but central seals a deployment only AFTER every node acks Applied,
and a FetchAndCache node cannot ack until it has fetched the artifact — seal-needs-ack ->
ack-needs-fetch -> fetch-needs-sealed. The node's fetch reached central and passed the
shared-key interceptor, then got a clean NotFound; the #485 apply-failure path correctly
kept last-known-good, but the deploy could never seal.
Direct mode reads the same ArtifactBlob from SQL while the row is still AwaitingApplyAcks,
so the serve path must too. Drop the Sealed gate: serve any deployment whose blob is
non-empty (unknown id / empty blob still collapse to NotFound — existence-hiding + #485).
Access is already gated by the interceptor, so there is no reason to hide a non-sealed
deployment a node is legitimately applying. The Task 2 'non-sealed -> NotFound' test flips
to 'non-sealed with a blob is served'.
Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW
Streams a sealed deployment's ArtifactBlob to a fetching driver node in
128-KiB chunks (matching the LocalDb cache chunk size). Unknown id, a
non-sealed deployment, and a zero-length blob all collapse to one
indistinguishable NotFound — existence-hiding plus the #485 serve-side guard
(never stream empty bytes as a valid empty config). The impl is named
DeploymentArtifactGrpcService to avoid colliding with the generated
DeploymentArtifactService container type.

The Secrets.Ui RCL's routable page was routed directly, but this host's
router is deliberately static (cookie SignInAsync needs SSR) with per-page
@rendermode opt-in - a directive the RCL page cannot carry, because the
other three family hosts render it under a globally interactive router
where a nested render mode throws. Routing straight to the RCL page
therefore rendered /admin/secrets with no circuit: it displayed, but every
@onclick was silently dead.
Fix: a host-side wrapper page (Pages/SecretsAdmin.razor) now owns
/admin/secrets, carries the standard per-page InteractiveServer render
mode, re-states the RCL page's own authorization policy (the router only
enforces [Authorize] on the routed component, which is now the wrapper),
and renders the RCL page as an ordinary child. The RCL assembly is
de-registered from both AdditionalAssemblies sites (router + endpoint) so
the route is unambiguous.
Guards: SecretsPageWiringTests pins the render mode (the #483 regression),
route parity with the RCL page, and policy parity; the page census in
PageAuthorizationGuardTests classifies the new page and admits the
secrets:manage policy. AdminUI.Tests 665/665.
Live-verified on the rebuilt docker-dev rig with Playwright: /_blazor
circuit negotiated on /admin/secrets and Add secret opens the editor
(before the fix: zero interactive markers, no circuit, dead click).
Closes#483.

Verify + regression-guard that the AdminUI driver-config editor persists secret:/
env:/file: refs verbatim and never resolve-then-resaves cleartext (which would
re-leak the secret into the config store, defeating G-2). Confirmed structurally
safe: DriverConfig is persisted as an opaque JSON string via RawTreeService, which
has NO secret-resolver dependency (only the DbContext factory) — resolution is
impossible on the save path. Resolution stays confined to driver-instantiation /
Test-connect (Tasks 7-8); GalaxyDriverBrowser resolves into a connect-scoped local
only, never writing back. Three round-trip tests (OpcUaClient Password/UserCertPassword,
Galaxy ApiKeySecretRef, env:/file: forms) exercise the real RawTreeService seam and
assert byte-identical save→reload. No product change (no leak found). 662 AdminUI tests pass.
MEDIUM-1: the editor<->authoring<->deploy invariant now holds on the ScriptedAlarm
surface too. CreateScriptedAlarmAsync/UpdateScriptedAlarmAsync validate {{equip}}/<RefName>
in BOTH the predicate script and the message template (via ExtractEquipReferenceNamesFromText),
matching what DraftValidator already enforces at deploy. Refactored ValidateEquipTokenAsync
into shared LoadEquipReferenceNamesAsync + CheckEquipReferencesResolve helpers.
LOW-1: LoadEquipReferenceNamesAsync uses IsNullOrEmpty (defense-in-depth) to match
EquipmentReferenceMap.Build; empty override is already normalized->null at the write path.
LOW-3: parity test hardened with two edge cases — unresolved-ref-left-intact (both seams
leave {{equip}}/X identical) and folder+tag-group RawPath ancestry.
Tests: VirtualTagEquipTokenValidationTests 9/9 (+3 SA), parity 4/4 (+2). AdminUI 659/0.

Replace the Batch-1-stubbed authored-tag flow with a UnsTagReference list on the
equipment page's Tags tab (v3 reference-only equipment): columns are effective name,
computed raw path, inherited datatype/access (read-only), display-name override
(editable), and remove. The retired equipment-authored-tag editor (TagModal.razor)
is deleted; the VirtualTag and ScriptedAlarm flows are untouched.
- "+ Add reference" opens a new AddReferenceModal that reuses RawTree in a new opt-in
PickerMode (Tag-leaf checkboxes + Device/TagGroup "select all tags below"), scoped
structurally to the equipment's cluster via LoadReferencePickerRootAsync (a single
cluster root — cross-cluster tags are unreachable, not merely hidden). Default /raw
usage is byte-unchanged (PickerMode defaults false).
- UnsTreeService (+ IUnsTreeService) gain the reference mutations:
LoadReferencesForEquipmentAsync (computes each RawPath via the shared RawPathResolver),
AddReferencesAsync (cluster-checked, all-or-nothing), RemoveReferenceAsync,
SetReferenceOverrideAsync, plus the picker helpers LoadReferencePickerRootAsync /
LoadDescendantTagIdsAsync.
- Consume IEffectiveNameGuard (constructor-injected, no-op fallback when unregistered):
AddReferences, SetReferenceOverride, and the VirtualTag + ScriptedAlarm create/update
mutations now call CheckAsync before persisting and surface a collision as the failure.
WP2 supplies the implementation + DI registration.
- Drop the retired equipment↔driver binding: remove DriverInstanceId from EquipmentInput,
the ImportEquipmentModal CSV column, the EquipmentPage Details driver select, and the
dead decision-#122 driver-cluster guard.
Tests: new UnsTreeServiceReferenceTests (add/remove/override, cross-cluster + duplicate
rejection, guard-consumed rejection via a fake guard, RawPath projection, picker helpers);
Equipment/Import test suites rewritten to drop the retired driver-guard cases. AdminUI
suite green (639 passed, 3 skipped); full solution builds 0 errors.

Extend RawTreeService.BuildRenameWarningsAsync so a tag/ancestor rename now
raises three warning kinds over the affected (prefix-scanned) tags:
(a) refined — historized WITHOUT a historianTagname override (default tagname
is the moving RawPath, so history forks); a pinned (override) tag no longer
warns. Count/message adjusted.
(b) unchanged — UNS-referenced (names the equipment).
(c) NEW — substring-scan every Script body for the affected tag's OLD RawPath
(ordinal, false-positives tolerated by design; no AST). OLD RawPaths are
recomputed from the pre-save in-DB topology via RawPathResolver.
CollectTagsBeneath* + TagsForDevices now carry (DeviceId, TagGroupId, Name) so
the OLD RawPath can be rebuilt. Contained entirely within RawTreeService.cs;
IRawTreeService + RawTree.razor untouched (warnings flow through the existing
RawRenameResult.Warnings). Note: a direct tag rename goes through UpdateTagAsync
(UnsMutationResult, no warning surface) so it is out of scope without widening
the interface.
Tests: new RawTreeServiceRenameWarningTests (4) — all-three, pinned-no-warn,
unrelated-empty, ancestor-rename script match. AdminUI.Tests 642 green.

Implements IEffectiveNameGuard (the Wave-A contract): per-equipment effective-name
uniqueness across UnsTagReferences (DisplayNameOverride else backing raw tag Name),
VirtualTags (Name), and ScriptedAlarms (Name). Ordinal comparison, self-row exclusion
by (kind, id), one pooled context per CheckAsync call. Registered Scoped in
EndpointRouteBuilderExtensions so WP1's UnsTreeService consumer goes live.
Verified the deploy-time DraftValidator UnsEffectiveNameCollision rule already
computes reference effective names from the backing raw tag's current Name (catches
rename-induced collisions), spans all three sources, compares ordinal, and names both
colliding sources + the equipment — no hardening needed. DraftSnapshotFactory already
loads Tags/UnsTagReferences/VirtualTags/ScriptedAlarms.
Tests: 8 guard tests (in-memory EF) + 3 deploy-gate tests (rename-induced collision,
override-vs-VT, ordinal case-sensitivity). All green.

Part 1 — rewire the three DriverType dispatch maps from hand-authored string
literals to the canonical DriverTypeNames constants (single source of truth):
- TagConfigEditorMap, TagConfigValidator (AdminUI)
- EquipmentTagConfigInspector (ControlPlane)
This FIXES the live drift ("TwinCat"->TwinCAT, "Focas"->FOCAS). The maps are
OrdinalIgnoreCase so behavior is identical; the value is no future drift.
Calculation is not added to the inspector (no CalculationTagDefinitionFactory.Inspect).
Added TagConfigDriverTypeNameGuardTests pinning the maps to the constants.
Part 2 — retire the routed /clusters/{id}/drivers driver-authoring flow (/raw
Waves A-C now cover driver/device/tag authoring end-to-end):
- Deleted DriverTypePicker, DriverEditRouter, the 8 *DriverPage shells, and the
ClusterDrivers list page.
- Removed the "Drivers" tab from ClusterNav. Routes /clusters/{id}/drivers* now
simply do not exist -> clean 404.
- The Forms/DeviceForms bodies, shared driver sections, and address pickers used
by the /raw modals are untouched.
Part 3 — updated PageAuthorizationGuardTests census: removed the 10 deleted
ConfigEditor pages + ClusterDrivers, updated group-count comments (ConfigEditor
21->11, AuthenticatedRead 17->16). Removed the now-dead Clusters.Drivers usings
from the 4 *DriverPageFormSerializationTests + the guard test.

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).

Extract the 8 typed driver pages into embeddable <Driver>DriverForm bodies
(channel/protocol config) and add per-driver <Driver>DeviceForm bodies
(connection endpoint -> Device.DeviceConfig, v3 endpoint split). New
DriverConfigModal + DeviceModal dispatch by DriverType (DriverTypeNames) for
the /raw tree; Test-connect inside DeviceModal builds the merged Driver+Device
config transiently via DriverDeviceConfigMerger. Routed pages now host the
form bodies and keep working. Round-trip + enum-serialization guard tests for
the Modbus driver form + Modbus device model; retargeted the existing
page-form serialization tests + the _jsonOpts converter guard to the forms.

Wave-A reviewer findings (no Critical/High):
- M-2: GlobalRaw auto-expands Enterprise roots so the Cluster level is visible on load (mirrors GlobalUns.ExpandStructural); clusters stay lazily collapsed.
- L-1: create mutations route SaveChanges through SaveCreateAsync — a lost sibling-name race (filtered-unique-index clash) becomes a friendly failure instead of an uncaught DbUpdateException.
- L-2: SaveDeleteAsync no longer leaks raw EF/SQL text; operator-friendly guidance.
- L-5: RawNode.ChildCount doc clarified (direct children only).
- Regression fix: PageAuthorizationGuardTests classifies the two new routable pages (/raw → ConfigEditor, /dev/context-menu-demo → AuthenticatedRead).
M-1 (ordinal vs SQL-collation sibling uniqueness) assessed benign: name indexes use the DB default collation and the server-side pre-check runs under that same collation, so pre-check and index agree — no case-variant rows can coexist, so runtime ordinal RawPath keying never collides.

Task 9: DiscoverTreeAsync UntilStable settle loop (FOCAS) — re-capture on a 1s interval until
the node set is non-empty and stable across two passes, bounded by open-timeout; on
timeout with a prior non-empty capture, return it (best-effort) instead of failing.
Task 11: BrowserSessionService resolves bespoke-first, falls back to IUniversalDriverBrowser
when no bespoke browser matches and CanBrowse is true; new CanBrowse on the service.
16 unit tests green (4 settle + 12 service).
Models gain an optional bool? Writable (absent stays omitted; explicit false round-trips,
unknown keys preserved); the six editors gain a Writable checkbox (FOCAS disabled+read-only
hint). 9 model round-trip tests green. docker-dev /run verify of one editor deferred-live.
The HistorianGateway driver is now the sole historian read/write+alarm backend, so the
Wonderware sidecar projects are dead code. Removes the 5 Wonderware projects (driver,
.Client, .Client.Contracts, + their 2 test projects) from the solution and tree, and fully
retires the vestigial 'Historian.Wonderware' driver type (UI/probe-only; it had no driver
factory): the Host probe registration, the AdminUI driver-config surface (driver page,
tag-config editor/model/validator entry, address picker/builder, driver-type catalog +
dropdown + edit-router entries), and their tests. Prunes the now-unused Wonderware
connection fields (Host/Port/UseTls/ServerCertThumbprint/SharedSecret) from
AlarmHistorianOptions (keeping Enabled + the SQLite store-and-forward knobs) and refreshes
the stale XML docs that named Wonderware as the production backend.

Code-review follow-ups: the page-coverage test now asserts every *DriverPage
declares a _jsonOpts serializer (so a new page that serialises config a
different way fails the guard, not just converter removal); clarify that 40 ==
(int)S7CpuType.S71500 in the numeric-throws test.
AdminUI driver-instance pages serialized enum config fields (S7 CpuType,
Modbus DataType/Region, AbCip PlcFamily, ...) as JSON *numbers* because each
page's _jsonOpts lacked a JsonStringEnumConverter. The driver factories,
however, deserialize into string-typed DTOs (+ lenient ParseEnum) and throw
when binding a JSON number to a string? — so an AdminUI-authored config
containing any enum field produced a blob the driver could not parse,
faulting the driver on deploy. Proven end-to-end for S7 and Modbus; latent
for AbCip/AbLegacy/TwinCAT/FOCAS/Galaxy/Historian. Only OpcUaClient was safe
(its factory + probe already carried the converter).
Add JsonStringEnumConverter to all 9 driver-instance pages' _jsonOpts and the
8 missing driver probes' _opts (factories unchanged — already string-via-
ParseEnum; strictly more permissive, also lets pages load hand-seeded
string-enum configs back into the form).
Also fix DriverProbeHandshakeE2eTests.AbCip_Green_AgainstSim to probe a real
sim tag (TestDINT) — the no-tags @raw_cpu_type fallback is rejected by the
ab_server sim with ErrorBadParam (a real ControlLogix returns ErrorNotFound,
which the probe treats as reachable; hardware-gated follow-up).
Tests: reflection guard over all driver pages' _jsonOpts (AdminUI.Tests);
factory round-trip + numeric-form-throws guards for S7 and Modbus.
Found by running the never-before-run FB-9/FB-10 live verifies.
Code-review nits: trim the seed name so the in-session dropdown label matches
the server-trimmed persisted name; add a null-selectedId test for
ResolveScriptLabel; and note in CreateNewScriptAsync that the ordering
invariant is proxied by the pure helper (AdminUI has no bUnit).
Code-review nits: SetFullName now throws on a blank reference (was silently
persisting FullName:null → silent deploy-time bind failure), and a new test
covers the alarm-typed re-pick combo (SeedDefaultAlarm over an already-edited
alarm leaves it intact).
After inline "New script" creates an SC-… id, the entry is now added
to _scripts BEFORE _form.ScriptId is set so the <InputSelect> has a
matching <option> on first render and the displayed label is correct.
Extracts VirtualTagModalHelpers.ResolveScriptLabel as a testable pure
helper (5 new unit tests in VirtualTagScriptDropdownTests).
