Codec-encoded scalars ("True", "42.5") reached RealOpcUaClient.WriteValuesAsync
as strings and were sent as String Variants, so a Boolean/Double node answered
BadTypeMismatch (0x80740000).
RealOpcUaClient now reads each written node's DataType attribute once per
session (batched, cached, cleared on connect/disconnect; derived types and
enumerations resolved via the supertype chain) and converts non-null scalar
values with the new OpcUaWriteCoercion table: Boolean, SByte..UInt64, Float,
Double, String, DateTime, Guid, all culture-invariant. Overflow, fractional
values to integer types and unparseable strings are refused client-side with
BadTypeMismatch and a message naming the value and target type - never a
rounded value. Arrays, null, unmapped types and nodes whose DataType read
fails pass through unchanged. WriteValueAsync now surfaces the outcome's own
status code instead of always BadNodeIdUnknown. MxGateway path untouched.
Tests: OpcUaWriteCoercionTests (coercion table incl. overflow, invalid and
culture-sensitive strings) and OpcUaWriteCoercionLiveTests (RequiresOpcUa:
String writes to Double/Boolean/UInt32 opc-plc nodes read back typed; reverting
the coercion reproduces 0x80740000). Component-DataConnectionLayer.md updated.
DeploySiteAsync's body moves into a private core taking the site plus an
optional area-id filter; site deploy behaviour is unchanged. The subtree is
one in-memory ParentAreaId walk (cycle-safe) shared by the deploy and the
preview. DeploymentService gains an ITemplateEngineRepository dependency for
the area lookups.
Under DisableLogin /auth/token deliberately answers 404 (lane K). The tests
now probe it: on a login-disabled rig TokenEndpoint_ReturnsJwt skips and the
bad-credentials test asserts 404 (the exchange is closed); with login enabled
they keep the 200 + JWT and 401 assertions.
The Topology page has loaded lazily (bounded instance pages behind 'Load
instances' loaders) since 9ee402bb (2026-09-09); TopologyAreaTests was
updated then but DeploymentActionTests still relied on one Expand-all click
revealing instance rows, so all four facts timed out locating the row. Move
OpenStableTopologyAsync into TopologyPageHelper and use it from both.
The rename input bound _renameBuffer with the default onchange trigger. A
browser fires change only after the Enter keydown (or on blur, which cancels
by design), so CommitRename always saw the original name and silently
no-oped: a UI rename never persisted. Present since the page was written
(pre-dates 513fa1aa); the Playwright test masked it by dispatching a
synthetic change event before Enter. Bind on oninput instead.
Tests: bUnit InlineRename_TypeThenEnter_PersistsNewName (fails on the old
binding); the Playwright rename test now types + Enter like an operator.
Also fix the Playwright OpenStableTopologyAsync race: it counted 'Load
instances' loaders immediately after clicking Expand all, before the
circuit re-render landed, and returned an unexpanded tree; it now waits
for no collapsed branch first.
Deploys are compile-warmed off the actor thread and reach the four-slot
predecessor-stop queue in warm-completion order (cross-instance ordering is
not guaranteed by design). Since SR-P5 moved the config deserialization into
that warm task, the fifth-sent deploy often finishes warming before one of the
first four, takes a slot, and Queued4 terminated inside the 100 ms no-message
window (16/20 failures under parallel load). The test now waits for the four
in-flight predecessors to terminate, cancels the one still alive, and also
asserts the cancelled redeploy is answered Failed/superseded.
L1: an artifact apply holding the slot past 10 min (ctor-overridable) logs an
Error site event naming it without releasing the slot; PostStop answers
queued applies Failed. L2: a boot-batch instance whose actor cannot be created
emits an Error site event and leaves the deployed set. L3: a failed enable
reverts the committed is_enabled (generation-bumped both ends). L4: the routed
SetAttributes batch Ask is the 30 s per-write bound plus 10 s mailbox slack.
ConnectionActorNames.Sanitize (shared by the DCL manager and the site deploy
gate) keeps ASCII letters/digits and -_.*+:@&=,!~';() only. The manager fails a
connection whose sanitised name is invalid or already used (Error + site
event) instead of restarting; DeployCompileValidator rejects a config whose
connection names collide after sanitising.
HandleOverridesLoaded now sends children a site-local AttributeValueSeed
(stream still gets the AttributeValueChanged). ScriptActor updates its
snapshot, Conditional truth value and Expression last result (seed-only eval,
never fires); AlarmActor evaluates it as a normal change.
DeployCompileValidator.WarmCompileCache dedupes script bodies/trigger
expressions across a batch and compiles them with Parallel.ForEach (half the
cores). CreateInstanceActorBatch starts the next batch's warm as it arms the
stagger timer; creation order and delay are unchanged. The warm's parsed
configs are reused at creation.
The deploy compile warm parses once off-thread; the parsed FlattenedConfiguration
rides DeployCompileWarmed to the gate (new Validate(FlattenedConfiguration)
overload), the redeploy buffer, CreateInstanceActor's DCL ensure and a new
InstanceActor constructor overload. Stored-row paths parse once inside
CreateInstanceActor; an unparseable stored row still fails init via S6.
