A driver named 'drv' (env form DRV) matched every sibling's id-form variable
env:<PREFIX>DRV_<12HEX>_... as 'another instance', breaking the recommended id
convention fleet-wide - including for a name that pre-dates the rule.
ReferenceNames is split into ReferenceNamesId / ReferenceNamesName; a reference
whose instance part is id-shaped (secret: DRV-<12 hex>, env: DRV_<12 HEX>[_...])
is matched by id only. DescribeNameChangeProblemsAsync also refuses new names
whose env form is DRV or starts with an id form (IsReservedInstanceName) at
create, /raw rename and config-modal update.

The deploy gate's merged-config path check is now one helper,
CredentialReferenceDeployChecks.MergedOnlyProblems (problems the runtime merge
reveals that the per-config checks do not), shared by the gate and
CredentialReferencePreflight.Scan - so an AuthType switch in one config and a
UserCertificatePath in the other is listed as a Draft finding '(merged with its
devices)' on the banner before a deploy refuses it.

RawTreeService.CreateDriverAsync / RenameDriverAsync / UpdateDriverAsync run
DriverConfigSaveGate.ValidateNameAsync -> DriverInstanceIdentities.DescribeNameChangeProblemsAsync:
- claim: the new name may not be the instance part (secret: segment or env: part)
of a reference STORED on another same-type driver's DriverConfig or DeviceConfig -
naming a driver 'gw' used to fail every sharer's next deploy;
- pin: a driver may not be renamed away from a name its own references are named
after (unless they also name its id or the new name) - the rename would free that
name for every other driver's save / Test Connect / browse. Re-pointing to the id
in the same config-modal save is allowed; a case-only rename is never refused.
Messages name the other driver, id, device and field path, never a value. The
driver + device reads are pinned on SQL Server by a [SqlServerFact].

env:<PREFIX><INSTANCE>_... is the per-instance convention for every prefix of a
driver's scope (OTOPCUA_GALAXY_, GALAXY_MXGW_, OTOPCUA_OPCUACLIENT_,
OTOPCUA_HEIDENHAIN_), INSTANCE = a driver id or name upper-cased with every other
character as '_'. A variable whose part after the prefix equals or starts with
(at a '_' boundary) ANOTHER same-type instance's id or name is refused with
CredentialReferenceOtherInstance at save, deploy, Test Connect and browse - the
same DriverCredentialPolicy.DescribeOtherInstanceProblems the secret: rule uses
(now over CollectInstanceReferences / ReferenceNames). Another-instance matches
win over the owner's, as for secrets. Shared variables that name no instance
(GALAXY_MXGW_API_KEY) keep working. HasInstanceSegments now also gates on env:,
so an env:-only browse needs the ConfigDb (fail-closed without it).

- AdminUI MTConnect driver form: "Comms-loss confirm (ms)" in the Reconnect section, always written
(0 = first refusal, negative = off is never dropped), case-insensitive load, unknown keys preserved,
advisory at >= 90000 ms (the watchdog fires first). Form output byte-pinned and parsed through
MTConnectDriver.ParseOptions on the driver side.
- Driver: a confirmed refused-connection outage now annotates every told CONDITION quality-only
BadNoCommunication (state/ack kept, once per outage, UNAVAILABLE-Bad skipped); the first delivery
afterwards re-diffs all subscribed conditions so unchanged ones get a quality-only Good.
- docker-dev/docker-compose.mtconnect-gate.yml: throwaway Agent in its adapter's network namespace so a
stop is a genuine ConnectionRefused (a plain stopped container is a DNS failure = ambiguous).
- Docs: MTConnect.md comms-loss section + live-gate recipe, docker-dev README, drivers.md rule.
Refs #852
DriverStatusPanel (the /hosts Controls dialog) showed one snapshot per driver - the most
recently published across both nodes of the redundant pair - so a driver Faulted on one node
and Healthy on its peer flipped on every publish. It now primes from the store's GetAll() and
keeps one entry per ReportingNodeId (DriverStatusByNode): per-node state chip in the header,
per-node last-success / 5-min errors / last error, per-node stale dimming. A snapshot with no
node id (pre-#847 publisher) renders unlabelled, sorted last. A primed copy older than a racing
live publish for the same node is dropped.
I-1: Test Connect / browse configs may carry unsaved edits (the device modal merges
the stored DriverConfig with the typed device config). The server
(DriverInstanceIdentities.EffectiveOwnerAsync, used by AdminOperationsActor and
BrowserSessionService) honours the named owner only when every endpoint value
(new DriverCredentialRules.EndpointFields: Galaxy Endpoint, OpcUaClient
EndpointUrl/EndpointUrls/DiscoveryUrl, Heidenhain Host/Port) is one that driver
stores; otherwise the owner is null and its instance-named secrets are refused.
Every Test Connect / browse whose config carries an in-scope secret:/env: reference
is recorded (CredentialUseAudit: IAuditWriter event category CredentialUse + a
structured Information line: user, driver, endpoint hosts, outcome).
L-1: the UserCertificatePath rule is skipped only in an object that explicitly sets
AuthType to non-Certificate (string or ordinal); the deploy gate also checks the
runtime-merged driver+device config so the switch cannot be split from the path; the
form no longer persists the hidden field.
L-2: a ConfigDb fault in the browse check is a refusal; RawBrowseModal catches open
failures into its error message.
L-4: a relative UserCertificateDirectory resolves against AppContext.BaseDirectory.

#835: inside one driver namespace, a secret:<ns>/<X>/... reference whose first
segment names ANOTHER existing same-type driver instance (id or name,
case-insensitive; another-instance match beats an own-name match, so renaming
one's driver after a victim's unlocks nothing) is refused at save
(DriverConfigSaveGate.ValidateAsync), deploy (CredentialReferenceOtherInstance,
Heidenhain included), Test Connect (TestDriverConnect.DriverInstanceId, ConfigDb
read off the mailbox) and live browse (BrowserSessionService, fail-closed without
a ConfigDb). One rule: DriverCredentialPolicy.DescribeOtherInstanceProblems +
DriverInstanceIdentities. Shared names and the driver's own id stay valid; env:
is not instance-scoped. Running drivers are unchanged (warn-only window: the
deploy gate and the upgrade preflight / /raw banner list them).
#836: OpcUaClient UserCertificatePath is a relative path inside
Drivers:OpcUaClient:UserCertificateDirectory (default
<LocalAppData>/OtOpcUa/pki/user-certificates). Syntactic rule (CredentialFilePaths,
a DriverCredentialPolicy path field) at every #815 seam; at load time
ResolveSecretRefsAsync joins, canonicalises and requires lexical AND
link-resolved containment before the PFX password is resolved, and
LoadCertificate refuses an unresolved path. A running driver's pre-#836 absolute
path keeps loading with a rate-limited warning (LegacyCredentialReferenceTracker.ReportPath).

User decision: save, Test Connect, live browse and the deploy gate keep
refusing out-of-namespace credential references, but an ALREADY-DEPLOYED
driver must not fault at the upgrade restart or (Galaxy) at the next
gateway reconnect, since ReopenAsync re-resolves Gateway.ApiKeySecretRef.
- LegacyCredentialReferenceTracker (Core.Abstractions): the one, deprecated,
call-site-chosen compatibility path. Running Galaxy (InitializeAsync,
ReopenAsync, ack fallback) and OpcUaClient (session open) pass it and keep
the pre-#815 semantics (case-insensitive prefixes, Galaxy file:, OpcUaClient
literal pass-through) with a rate-limited Warning (driver/field/allowed
form, never the value) and a credential-compat:<field> diagnostics entry
(both drivers now implement IDriverDiagnostics). Browsers and probes pass
none and stay hard-fail; Heidenhain has none.
- Deploy-gate message names the migration.
- Upgrade preflight: CredentialReferencePreflightService (admin nodes, once
after ApplicationStarted, ConfigDb only, resolves nothing) logs a Warning
per Draft row / Deployed-artifact finding; the /raw banner shows them plus
Running drivers reporting warn-only use (driver-health diagnostics).
- docs/security.md: exact replacement table (incl. the old form default
env:MX_API_KEY, file:, un-namespaced secret:, casing changes), the
ReopenAsync reconnect behaviour, the warn-only window and its removal.

- RawTagRowRules: the ONE driver-dispatched authority on Tag-ROW rules (access level /
Tag.DataType). RawTreeService's save path, the CSV import's staged review grid
(RawTagCsvMapper) and the manual-entry grid all call it; no call site names a driver.
A ReadWrite or mistyped Heidenhain row is now invalid IN THE PREVIEW instead of only at Commit.
- Manual-entry grid + tag modal: when the driver dictates the data type for the row's
address (RawTagRowDefaults.DictatedDataType), the field is a locked read-only value instead
of a select that commit silently replaced; the grid runs the row rule client-side and no
longer rewrites the row at commit.
- Driver/device modals: the credential refusal is shown once (the modal's save-gate notice);
HeidenhainDriverFormModel / HeidenhainDeviceModel.Validate report only ranges / endpoint.
- docs/drivers/Heidenhain.md: #831 alarm conditions + rediscovery, #830 authoring behaviour.
Tests: HeidenhainAuthoringUxTests (CSV preview == ImportTagsAsync row-for-row, dictated type
is what the save path accepts, single credential surface, ALARM: seeding, CSV alarm rows,
AlarmMs round-trip); HeidenhainAuthoringTests updated for the single-notice rule.
- ALARM: selectors (HeidenhainAlarmSelector, Contracts): ALARM:*, ALARM:OTHER,
ALARM:CLASS=<r>[/GROUP=<r>][/NUMBER=<r>] (<r> = n | lo..hi; negative numbers allowed).
An ALARM: address and the cross-driver alarm object only work together — the factory
refuses either alone, so editor, save path, CSV and deploy inspector agree. Data type
fixed Boolean; never a value (ReadAsync BadNotSupported), never in a data subscription.
- HeidenhainDriver implements IAlarmSource: one condition per ALARM: tag at its RawPath,
driven by the SAME allowlisted R_RI 27/28 walk on the control's single loop, on the new
Polling.AlarmMs cadence (default 2000 ms, only for controls carrying an ALARM: tag).
FOCAS #647 transition rules (Raise / Retrigger / Clear), identity = class+group+number+text,
deterministic display order, told-record on the driver instance, recorded only while a
handler listens. A failed walk (refusal, overflow, comms loss) is quality-only, never a clear.
- Acknowledge is LOCAL-ONLY: AcknowledgeAsync is a no-op success (FOCAS/MTConnect posture);
Lsv2ReadOnlyPolicy is unchanged — no ack or write request exists.
- Opt-in per tag, no driver flag (FOCAS #647 / MTConnect #626 precedent); Alarms/* arrays unchanged.
- IRediscoverable: a reconnect whose R_VR identity (model / NC / PLC / options) differs from
the previous session raises OnRediscoveryNeeded once (advisory re-browse chip). No extra traffic.
- AdminUI: Heidenhain joins NativeAlarmModel's alarm drivers; the typed editor fixes ALARM:
tags at Boolean and seeds/drops the alarm object with the selector; driver form gains
"Alarm conditions (ms)". (HeidenhainDriverFormModel also carries the #830 credential-notice change.)
Tests: HeidenhainAlarmTests (grammar, pairing, rules, simulator e2e with the captured iTNC 530
alarm record, local-only ack = zero bytes sent, quality-only outage/refusal, rediscovery),
Runtime.Tests HeidenhainNativeAlarmEndToEndTests (real DriverHostActor condition), a
DraftValidator case, and the NativeAlarmDriverSetGuard now scans the Heidenhain driver.
#816 finding: the SDK checks that the server certificate names the host only
when a session is created with checkDomain:true. The driver, the AdminUI
browser and Client.Shared all called the 8-argument
DefaultSessionFactory.CreateAsync, which forwards checkDomain:false — so no
host-name check ever ran (why a trusted NAT cert for *.invalid browsed fine
over an IP in #813). When enabled the SDK (Session.OpenAsync ->
ValidateDomains -> FindDomain) compares ConfiguredEndpoint.EndpointUrl.IdnHost
— the CONFIGURED host, because OpcUaEndpointSelection/EndpointSelector
rewrote the advertised one — against the cert's DNS/IP SANs; secured
sessions only, and the auto-accept handler accepts a mismatch.
Policy: certificateValidation.validateServerHostName, tri-state. Unset =
OpcUaCertificateValidationOptions.DefaultValidateServerHostName = false, the
pre-#816 behaviour, so nothing changes on upgrade; true = validate the
configured host; false = explicit NAT/port-publish opt-out. Threaded into the
driver, the AdminUI browser (same JSON) and the AdminUI form (a select that
keeps "unset" unset), Client.Shared ConnectionSettings.ValidateServerHostName
and the CLI --validate-host-name. A driver refusal names the opt-out.
#818: the NAT fixture's /app/pki is on the opc-plc-nat-pki volume (verified:
same thumbprint across --force-recreate), its PUBLIC cert is committed as
Docker/nat/opc-plc-nat-server.der, and NatPublishedEndpointBrowseTests run
every secure browse on a throwaway PKI (internal browser seam): refusal with
nothing trusted, positive with the cert trusted (unset/false host check), and
a BadCertificateHostNameInvalid refusal with the check on. The trusted cert is
OPCUA_NAT_SERVER_CERT or the committed one (skip on thumbprint mismatch);
OPCUA_NAT_SERVER_CERT_TRUSTED is retired. CI exports its throwaway NAT
container's public cert. ServerHostNameValidationTests pin the driver against
the plain opc-plc. MIN_EXECUTED not raised (needs a hosted run): +6 in
v2-integration (440 -> 446), documented in scripts/ci/README.md.
A Designer could point a Galaxy / OpcUaClient endpoint at a host they control,
set a credential field to any reference the node can resolve
(env:ConnectionStrings__ConfigDb, env:ServerHistorian__ApiKey, secret:<any>,
Galaxy file:<any path>) and click Test Connect / live browse; the node resolved
the value and sent it to that host.
One shared rule in Core.Abstractions (CredentialReferences +
DriverCredentialPolicy) generalises the #803 Heidenhain namespace:
- Galaxy: secret:galaxy/... | secret:otopcua/galaxy/... | env:OTOPCUA_GALAXY_... |
legacy env:GALAXY_MXGW_...; file: refused; dev:/literal API key unchanged.
- OpcUaClient: secret:opcuaclient/... | env:OTOPCUA_OPCUACLIENT_...; literals unchanged.
- Heidenhain adopts the shared parser/resolver (namespace unchanged).
Enforced at the AdminUI save path (DriverConfigSaveGate), the deploy gate
(CredentialReferenceDeployChecks, code CredentialReferenceOutOfScope), Test
Connect (AdminOperationsActor, before any probe), live browse
(BrowserSessionService, before any browser) and again at resolve time in every
driver/browser (fail closed, before any store/env read).

The shared RawConfirmDialog sat inside the Alarms tab branch, so Remove
reference (Tags) and Delete virtual tag (Virtual Tags) set it visible on
a page that did not render it. Pinned by brace depth in
DeleteConfirmationWiringTests.
- Review 1: RawTreeService Create/UpdateDriver and Create/UpdateDevice refuse a Heidenhain
config whose password fields are not blank / secret:heidenhain/... / env:OTOPCUA_HEIDENHAIN_...
(DriverConfigSaveGate over HeidenhainOptionsParser.DescribeCredentialProblems: top level,
Access, Devices[], case-insensitive keys; the value is never echoed), so a literal password
never reaches the draft DB. The driver and device modals show the reason and disable Save.
- Review 8: CreateTag/UpdateTag/ImportTags (tag modal, manual entry, CSV import, browse commit)
refuse a ReadWrite Heidenhain tag or a Tag.DataType that disagrees with what the driver
publishes (HeidenhainTagRules: catalog type, Float64 => Double, or the binding's dataType).
The tag modal and manual-entry grid fix the access level at Read and derive the data type from
the address (RawTagRowDefaults). New deploy gate HeidenhainTagDataTypeMismatch.
- docs/drivers/Heidenhain.md: credential namespace convention + why, the save-path and deploy
enforcement, optional-role credential behaviour, BadConfigurationError, backoff/ordering notes.
Tests: HeidenhainSavePathTests (service save path; red with the gates disabled) and new
DraftValidatorHeidenhainTests cases.
Central pin 1.1.0 -> 3.2.2; AdminUI/ControlPlane/Runtime/Host.Tests no longer carry VersionOverride.
The three driver IntegrationTests fixtures' Fact/Theory attributes gain the source-info ctor (xUnit3003).

Proven broken first: VirtualTagToVirtualTagFlowTests (real mux + host + Roslyn
evaluator) failed on master - VT A evaluated, VT B reading A by its key never did.
VT outputs only reached their OPC UA node; the mux carried driver values only.
- VirtualTagHostActor also sends each real result (not re-asserts) and a disabled
tag's BadOutOfService to the mux as VirtualTagOutput, keyed by the VT's UNS
NodeId identifier {EquipmentId}/{Name}. Publish path unchanged (single source).
- DependencyMuxActor pins VT outputs (retained with no subscriber, no grace,
immune to SourceRemoved) and replays them; VirtualTagOutputsRemoved releases
keys that leave the deployed set.
- DraftValidator: blocking VirtualTagDependencyCycle (A->B->A, self-read, loops
through Calculation tags, {{equip}} refs resolved); disabled VTs are not nodes.
EquipReferenceUnresolved names the key form when {{equip}}/<name> is a VT.
- Runtime backstop: the host re-detects VT cycles per apply and does not route
outputs of tags on one.
- AdminUI ScriptTagCatalog lists VTs by key (the bare leaf name never resolved).
- docs/VirtualTags.md documents the routing, key, retention and cycle rules.

Item 2: a tag's optional `write` block picks the statement the driver builds from its own
catalog-validated identifiers (no authored SQL; values always bound):
- Update (default, unchanged back-compat UPDATE ... WHERE key; 0 rows = BadNoData)
- Insert (key+value[+stamp]; append for a WideRow topByTimestamp tag)
- Upsert: SQL Server MERGE WITH (HOLDLOCK), PostgreSQL INSERT ... ON CONFLICT, MySQL
ON DUPLICATE KEY UPDATE (1-or-2 rows), Oracle MERGE from DUAL
- Procedure: named stored procedure resolved against the routine catalog by the catalog gate
(INFORMATION_SCHEMA.ROUTINES / ALL_PROCEDURES), value/key/timestamp params by name (MySQL positional)
- stampTimestamp sets the tag's timestamp column to the write time (UTC)
Odbc serves Update/Insert only (shared SqlWriteSupport table). Constraint failures map to
BadEntryExists (unique) / BadOutOfRange (other integrity, data exception); everything else,
permission denied included, stays BadCommunicationError. WriteIdempotent stays false.
The parser refuses malformed blocks (strict keys/enums/param charset); DraftValidator emits
blocking SqlWriteBlockInvalid / SqlWriteModeUnsupported from the driver's own parse; the AdminUI
editor surfaces the same message.
Items 1 + 4 (docs/drivers/Sql.md): ODBC stays the ANSI SQL:2008 profile (native providers for
SQL Server/MySQL, DB2 unsupported) with an ops note on driver manager + vendor driver on every
Odbc and AdminUI host; read-only drivers require a SELECT-only login, writable drivers a login
limited to their write targets.
Tests: SqlWriteModeTests (parse, every dialect's SQL, gate, status map, SQLite end-to-end),
DraftValidatorSqlWriteBlockTests, AdminUI round-trip; live SqlWriteModesLiveTests on SQL Server,
PostgreSQL, MySQL, Oracle (seeds gain write_targets + set_target) and an Odbc write leg.

allowWrites is no longer inert: SqlDriver implements IWritable, default off.
- Gates (outermost first): node Writable + WriteOperate (server), driver
allowWrites, the tag's own TagConfig "writable": true (strict JSON boolean;
anything else refuses the tag, and the deploy gate says why), and a model that
names exactly one row — KeyValue, or WideRow by where-pair. topByTimestamp and
Query are BadNotWritable.
- SqlWritePlanner: the only statement a write can become is
UPDATE <table> SET <value col> = @v WHERE <key col> = @k, built from the
catalog-gate-canonical identifiers (dialect-quoted) with value and key bound;
value-before-key marker order so positional ODBC binds correctly. No authored
write SQL, INSERT, UPSERT or procedure.
- Executed in a transaction that commits only when exactly one row was touched:
0 rows -> BadNoData (never inserts), >1 -> rolled back, BadConfigurationError,
unknown count -> rolled back, BadNotSupported. Bounded by operationTimeout;
provider errors -> BadCommunicationError; health untouched.
- Discovery advertises Operate only where a write could succeed.
- AdminUI: driver form's Allow writes switch is live; tag editor gains a
per-tag write switch; model validates writable strictly (parity corpus).
- Factory no longer warns "allowWrites ignored"; it logs whether writes are on.
- Tests: SqlWriteTests (planner SQL/bind order/injection/coercion, every gate,
readback, absent key, two-row rollback, gate-rejected tag, discovery);
MySqlReadTests write legs against InnoDB (keyed row only, two-row rollback,
server-side grant refusal, default-off). Seed adds a setpoints table and the
one UPDATE grant.

SqlProvider.Odbc is now constructed; every enum member is a working backend.
- OdbcDialect: System.Data.Odbc 10.0.14 (no vulnerable packages), ANSI double-
quote quoting, positional `?` markers, INFORMATION_SCHEMA catalog (system
schemas of the common backends excluded by name — the live gate caught
psqlODBC listing pg_catalog), FETCH FIRST n ROWS ONLY limits, a conservative
1000-parameter chunk. Positional binding is safe because every caller adds
parameters in marker order (planner IN list, catalog schema-then-table).
- Named queries on a positional provider are checked by `?` count against the
declared params (literals/comments ignored), since there is no name to match.
- Supported backends are those whose SQL accepts that profile (PostgreSQL via
psqlODBC proven, Snowflake-like); SQL Server/MySQL/DB2 should use their native
provider. The host needs the ODBC driver manager + vendor driver.
- Reserved-provider controls in factory/probe/browser tests now use an
undeclared ordinal (99); the AdminUI form offers Odbc and a test pins the
dropdown theory to SqlDialects.Supported.
- Tests: OdbcDialectTests (unit, any host). OdbcReadTests + Docker/odbc/
run-odbc-gate.sh run the built suite in a throwaway Linux SDK container with
unixODBC + psqlODBC against a throwaway seeded PostgreSQL: KV IN-list
positional binding, where-pair, topByTimestamp via FETCH FIRST, a two-
parameter named query, and the browse walk. macOS has no vendor ODBC driver,
so there the suite skips.
(lmxopcua#753)
Claude-Session: https://claude.ai/code/session_01GT67AEHd2Acv1YPwGfXEoV
SqlProvider.MySql is now a constructed backend instead of a reserved name.
- MySqlDialect (Driver.Sql.Dialect): MySqlConnector 2.6.2 (MIT, fully managed,
no vulnerable packages), backtick quoting with MySQL's 64-char / no-trailing-
space rules, information_schema catalog SQL with the database as the schema
(system databases excluded, aliases pinned), trailing LIMIT, a type map that
also reads the reader-side spellings (INT UNSIGNED -> UInt32, BOOL -> Boolean).
- SqlDialects: the one provider -> dialect map. The factory, the Test Connect
probe and the browse picker each carried their own switch (and drifted once);
they now all read this, and their refusals list the supported/reserved sets
from it.
- AdminUI driver form offers MySql.
- Tests: MySqlDialectTests (golden quoting/catalog/type map/planner SQL); the
provider-gate tests in factory, probe, browser and form now treat MySql as
supported and Odbc as the reserved control. MySqlReadTests + Docker/mysql
(throwaway mysql:8.4, SELECT-only login): liveness, KV/wide-row/topByTimestamp,
INT keys vs authored text, case folding against case-sensitive table names,
catalog rejection, browse walk, factory+probe, named query with a bound
parameter, and a writing stored function whose effect the rolled-back
transaction discards.
(lmxopcua#753)
Claude-Session: https://claude.ai/code/session_01GT67AEHd2Acv1YPwGfXEoV
SqlTagModel.Query (design §5.4) is now served end to end instead of refused.
The driver config declares `queries` (name -> sql, params, maxRows); a tag names
the query, the result `column` it reads and optionally a `rowKey` picking its row.
- Parser/deploy gate: query + column required, rowKey all-or-nothing; Inspect
explains each refusal. Table is not read for this model.
- SqlReadOnlyStatement: single SELECT/WITH only, no data/schema-changing keyword
outside literals/comments (refuses SELECT INTO, FOR UPDATE, DML CTEs). Shared by
the factory and the AdminUI driver form (SqlNamedQueryRules.Describe), so the
form refuses what the driver refuses. One bad entry fails the driver.
- Parameters are always bound; the factory refuses a declared parameter whose
dialect marker the statement never uses.
- Reader: one execution per query per poll, inside a transaction that is always
rolled back; result columns matched exact-then-unique-CI; no row -> BadNoData,
ambiguous row / missing column / over maxRows -> BadConfigurationError.
- Catalog gate passes Query tags through (nothing is quoted into SQL); a
Query-only driver skips the catalog load. A tag naming an undeclared query is
skipped with the reason on /hosts.
- AdminUI: typed editor offers Query (query/column/rowKey); driver form edits
`queries` as JSON and keeps the last valid set on a typo.

Akka TestKit's AwaitCondition without an interval polls every max/10 of the
DILATED budget. Measured here: a condition that turned true at 2 s under a
15 s budget returned after 3003 ms at timefactor 1 (3 polls) and 4502 ms at
timefactor 3 (2 polls). AwaitAssert / AwaitAssertAsync are unaffected (a
fixed 100 ms: 21 polls in ~2 s at both factors).
RuntimeActorTestBase and ControlPlaneActorTestBase now declare
AwaitCondition overloads that hide TestKit's and default the interval to
PollInterval (20 ms), so every subclass call without an interval binds to
them (measured after: returns 5-22 ms after the condition holds, at both
factors). PresenceBudget's doc no longer claims the helpers return "the
instant the condition holds" - it states the per-helper poll behaviour.
Bare-TestKit classes with AwaitCondition calls get an explicit interval:
TelemetryDialDeadlineTests / TelemetryDialSupervisorTests (next to their own
undilated 5 s / 8 s WaitForCount deadlines and a 1 s dial deadline) and
OpcUaEndpointStepDownActorTests (RuntimeActorTestBase.PollInterval, now
public like PresenceBudget). ContinuousHistorizationRecorderTypedValueTests'
AwaitConditionAsync was left alone (historian code is being changed in
parallel).
Suite results (Release, 0 warnings):
- Runtime.Tests 946/3 skipped/0 failed at timefactor 3 (1 m 45 s, was
2 m 57 s) and 1 (1 m 18 s, was 2 m 57 s);

CSV: IsArray with blank/0 ArrayLength is the variable-length shape browse-commit and the composer produce, so its own export now re-imports.
Plain MQTT: MqttTagDefinitionFactory.Inspect (the driver's parse, consulted by the authoring inspector) now advises when isArray is set on a Plain-shaped tag; Sparkplug-shaped blobs stay quiet.
Live Sparkplug array test and SDK reflection items remain open.
Claude-Session: https://claude.ai/code/session_01GT67AEHd2Acv1YPwGfXEoV
R06:M-5 made Sparkplug *Array leaves unbindable because the ingestor refused
them. The ingestor now decodes the packed bytes_value of all 13 array types
(new SparkplugArrayCodec: LE fixed widths, int64-ms DateTime, uint32-count +
MSB-first BooleanArray, NUL-terminated UTF-8 StringArray; golden vectors are
the spec's examples, reproduced byte-for-byte by SparkplugNet 1.3.10) and
publishes a typed 1-D array through the scalar coercion, all-or-nothing.
Shape uses the fleet's one array model: the tag's platform isArray/arrayLength
keys (ValueRank=1, ArrayDimensions=[arrayLength] or [0] = variable length).
The driver reads them with TagConfigIntent's exact semantics and never rejects
on them, so composer, driver, authoring model and deploy inspector agree
(MqttArrayShapeParityTests). Shape mismatch (array metric on a scalar tag, or
the reverse) is BadTypeMismatch - a String tag no longer gets the packed
buffer as base64; a malformed body or a length differing from a declared
arrayLength is BadDecodingError (MTConnect #627 verdict). Template/DataSet
members of an array type take the same path. Arrays stay read-only (encoder
refuses them; MQTT is not in DriverArrayWriteSupport).
Browser: array leaves are bindable again and state isArray in AddressFields;
the commit mapper writes "isArray": true (no arrayLength). Discovery reports
IsArray/ArrayDim. Docs: Mqtt.md "Array metrics", design table, drivers rule.
Tests: codec (golden + malformed), ingest through the real codec + Dispatch
(the project's MiniBroker never forwards a PUBLISH, so there is no in-process
broker harness), browse, discovery, commit mapper, parity corpus. Mutating the
fix back out fails 18 MQTT + 9 AdminUI tests.

AbLegacyDriver stamped LastSuccessfulRead (init, read, write), the read's sample
timestamps and host-state change times from raw DateTime.UtcNow; only the backoff
path read the injectable Clock. All of them now read Clock(), so
NativePcccBridgeStatusHealthTests drives a manual clock (init at T0, read at T1)
and asserts LastSuccessfulRead == T1 exactly instead of spin-waiting for the wall
clock to pass the init stamp (#767). Without the driver change the 6 tests fail
(init stamp is wall-clock, not T0).
Directory.Build.props sets TreatWarningsAsErrors for every project since #766, so
the 75 per-csproj copies (64 src + 11 tests) are removed and the props comment
says it is now the only place. tools/mem-probe keeps its explicit opt-out.
Release build: 0 warnings, 0 errors; a planted CS0168 still fails the build in a
src project and in a test project that used to carry its own copy.

mxaccessgw 488649c+ acknowledges by AuthenticateUser as the operator and
writing <alarm>.AckMsg, so AcknowledgeAlarmRequest now needs a real Galaxy
operator_user + operator_domain + operator_password. The OPC UA data plane is
API-key/anonymous and carries no Galaxy password, so the driver resolves the
account per ack:
1. the session's API key's Galaxy ack identity, set on AdminUI /apikeys and
held ONLY in the encrypted Secrets store
(otopcua/apikeys/<keyId>/galaxy-ack-{user,password}); a key with a user but
no password secret is refused, never silently downgraded;
2. else the driver instance's AlarmAck fallback account (DriverConfig
FallbackUser/FallbackDomain/FallbackPasswordSecretRef; secret:/${secret:}/
env:/file:/dev: only — a literal is refused);
3. else DriverOperationRefusedException: nothing is sent, never an empty
operator_user. Refusals are excluded from the resilience retry/breaker.
- Pins ZB.MOM.WW.MxGateway.Client/Contracts 0.2.1 -> 0.3.0 (vendored into
nuget-packages/ from the Gitea feed, per the local-mxgw source mapping).
- The session ApiKeyId (not a secret) rides NativeAlarmAck ->
RouteNativeAlarmAck -> RouteAlarmAck -> AlarmAcknowledgeRequest; the password
is resolved in the driver and never travels through actor messages.
- The OPC UA principal + key id are appended to the AckMsg comment
("[OPC UA: <principal>, key <id>]") and logged, so a shared fallback
account does not lose who acknowledged.
- Password never logged: GalaxyAckCredential.ToString omits it, the
acknowledger scrubs it from every gateway message it echoes and withholds
any exception that echoes it; audit rows carry only the key id.
- AdminUI: /apikeys "Ack identity" editor (set/remove; delete-key clears it),
Galaxy driver form gains the fallback section.
- Synchronous OPC UA status for a refusal is follow-up #760 (the native ack
path is fire-and-forget after the Part 9 method returns).
Tests: request mapping (password populated), password absent from logs and
exception text (mutation-checked), key-mapped / fallback / refused paths at
resolver and driver level, breaker non-trip, key-id propagation through node
manager and DriverHostActor, AdminUI service + form round-trip.
Closes#749
Staleness is not a liveness proof: DriverInstanceActor publishes on a 30 s
tick and dedups on a health fingerprint, so a running Faulted, idle or
tagless driver deleted in /raw (undeployed) went stale and was evicted.
DeployedDriverSet reads, per node, the latest and latest-Applied
NodeDeploymentState deployments plus the latest Sealed one, parses each
artifact's DriverInstances once (cached by deployment id, pruned to the live
set, only the blob column of an uncached row is read), and /hosts unions it
with the authored set. The staleness clause stays as a second guard. An
unreadable artifact or a failed read means 'unknown' and skips eviction.
The Hosts.razor comment claiming '~12 health publishes' is corrected.
N-new-2: the CSV download's Content-Disposition carries an RFC 5987
filename* via ContentDispositionHeaderValue.SetHttpFileName.

I1: /hosts eviction keyed off the AUTHORED DriverInstances, so a driver
deleted in /raw but not yet deployed - still running, still publishing -
vanished every tick. The stores' sweep is now EvictUnconfiguredStale(set,
olderThanUtc): an entry goes only when unconfigured AND its PublishedUtc is
older than 60 s. Tests cover unconfigured+fresh kept (positive control),
unconfigured+stale evicted, configured+stale kept, and the deploy hand-off.
M1: Test Connect falls back to the driver's documented ProbeTimeoutSeconds
default (Galaxy 30, OpcUaClient 15, ...) when the key is absent.
M2: the budget never undercuts the config's root timeoutMs (+1 s).
M5: RawBrowseModal compares the open generation captured before the await,
so a close-then-reopen mid-open closes the stale session.
M6: /alarms-historian keeps a 30 s re-poll on 'not registered' (a driver
node may still be starting) instead of stopping for good.
M7: /scripts source fetch failure shows in the dialog, not the error boundary.
M8: the export modal maps only its preview rows; the endpoint writes via
Results.Text (no second byte[] copy).
M9: /hosts config queries are ordered, so SequenceEqual change detection holds.
N1 tooltip, N2 CRLF-safe regex, N3 throttled Warning for subscriber faults,
N5 equipment-import help text now describes RFC 4180 quoting.
H3: MonacoEditor documents that themes are page-global.

RequestRebirthAsync now returns only once the requested births have arrived
and gone quiet, but the modal still told the operator to re-expand the tree in
a few seconds. ConfirmRebirthAsync re-keys the tree against the same session
(as the Refresh button does) when the session and modal are still current,
drops the now-stale armed scope, and keeps the outcome line.

Since R06:M-5 the Sparkplug browser states no address for a metric the
ingestor will not read and labels its descriptor 'not bindable', but the commit
refusal still said the attribute lookup returned nothing. RawBrowseModal keeps
the attribute's descriptor on the selection, and DescribeUncommittableLeaf
reports a 'cannot be bound in this version' message echoing it. A lookup that
really returned nothing keeps the old text. A test pins the marker to the
browser's own string.

/fleet/diagnostics was reachable only by URL: each driver-role row on /fleet now
links to it (FleetDiagnosticsLinks.For escapes the host:port node id). The
diagnostics table showed the string instance id because the wire carries no
display name; the page now joins the authored DriverInstances.Name from the
ConfigDb (enrichment only - a failed lookup falls back to the id) and keeps the
id beneath the name.

The dev-only demo page shipped routable in the production assembly. Its route
moves from @page to a code-behind [Route] under #if DEBUG, so a Release build
keeps the component type (nothing referencing it breaks) but has no /dev/*
route. The page-authorization guard classifies it under #if DEBUG, and
DevRouteGatingTests asserts each configuration's half (Debug: exactly the demo
route; Release: none) with a positive control. Both configurations pass.
