Interface goes to Commons.Interfaces.Services and the state record to
Commons.Messages.Health, so CentralCommunicationActor no longer needs the
HealthMonitoring namespace. Implementation stays in HealthMonitoring.

Enables transitive pinning so the central SQLitePCLRaw.lib.e_sqlite3 2.1.12
pin applies everywhere (41 projects verified at 2.1.12). Required raising the
central floors: Newtonsoft.Json 13.0.4 and Microsoft.Extensions.* 10.0.13.

Attribute/alarm/script add (collision check) and update (parent-lock lookup)
used GetAllTemplatesForAnalysisAsync, materialising every template, attribute,
alarm and script in the library per edit. They now call the new
ITemplateEngineRepository.GetTemplateAnalysisClosureAsync: the same untracked,
body-free analysis projection, restricted to the template's inheritance chain
plus the composition closure of every chain member - exactly what
TemplateResolver and CollisionDetector walk (a composed module's own parent
chain is never climbed, so it is not loaded). Adds use the edited template's
closure, updates the parent's.
The walk (Commons TemplateAnalysisClosure) loads one batch per closure depth,
requests each id once, terminates on cycles and skips dangling edges.
Evidence:
- TemplateAnalysisClosureTests: for every template of a graph with chains,
nested + diamond compositions, a derived module, cycles, dangling edges and
colliding unrelated templates, ResolveAllMembers / DetectCollisions /
FindMemberByCanonicalName answer identically from the closure and the whole
graph (mutation-checked).
- TemplateAnalysisClosureRepositoryTests (SQLite, recorded SQL): 6 templates /
12 attributes loaded instead of 47 / 94, in 4 queries (one per depth),
untracked, script bodies never selected.
- TemplateServiceTests: two new tests with the whole-graph load wired to throw
(fail on the old service); every existing add/update test now runs against
the closure via AnalysisClosureMock.
ReconcileDescendantsAsync still loads the tracked full graph; not in scope.

The live AlarmStateUpdate already carried ack_time (24) but the Debug View
snapshot DTO did not, so snapshot-seeded alarm rows showed a null ack time
until the next live update. Additive google.protobuf.Timestamp ack_time = 21
(absent => null, including from a pre-#84 site), vendored C# regenerated with
docker/regen-proto.sh sitecommand, mapped both ways in SiteCommandDtoMapper.
The native golden sample now sets AckTime (the computed one leaves it null),
so the round-trip golden pins both the present and the absent decode.

The bundle importer writes external systems, methods and database connections
through the raw DbContext, bypassing the ManagementActor handlers that
invalidate ExternalDefinitionLookupCache (#65), so the importing node served
pre-import definitions for up to DefinitionCacheTtl. New Commons seam
IExternalDefinitionCacheInvalidator, implemented by the cache and registered as
the same singleton; BundleImporter takes it optionally and invalidates once
after every committed import (never on rollback; never throws).
Peer-central-node invalidation (the other half of #83) is NOT done here: the
issue leaves open whether the 10 s TTL bound is acceptable for the peer.

ScriptCallResult and RouteToCallResponse gain trailing Truncated/LogsTruncated,
filled from the site FlowTraceCollector after Complete(); RouteToCallResponseDto
fields 8/9 carry them (sitecommand regen). FlowDebugRunner ORs them into
FlowDebugRunResult on the script entry, and on the method entry through a new
optional truncation sink on RouteHelper.WithTraceSink (carried through every
With* clone). Previously a site run whose collector dropped rows came back as a
silently short list. Older sites send false.

Central's Debug View live stream and Alarm Summary cache always saw false
because neither wire message had the field. Additive proto fields, vendored
C# regenerated with docker/regen-proto.sh (sitestream + sitecommand), mapped
both ways in StreamRelayActor/SiteStreamGrpcClient and SiteCommandDtoMapper.
The live stream publishes Alarm Actor events, which never carried the flag,
so InstanceActor.HandleAlarmStateChanged now stamps it before retaining and
publishing. A pre-#60 site sends the proto3 default. No UI badge yet.

SiteScriptCompileCache now records each eviction sweep on scadabridge.site.script_compile_cache.evictions
(ScadaBridgeTelemetry). It rides the existing ZB.MOM.WW.ScadaBridge meter, which is already in
SiteServiceRegistration.ObservedMeters, so no new allowlist entry is needed; a Host test pins that
the meter stays allowlisted.
Each cached client records when it was last handed out; a periodic sweep (half of the new
CommunicationOptions.GrpcClientIdleTtl, default 30 min, 0 disables) disposes and removes entries
unused for the TTL that have no live subscription (SiteStreamGrpcClient.ActiveSubscriptionCount).
Lookup and the sweep's check-and-remove share one lock so a handed-out client is never disposed
under its caller; an evicted client is re-created on next GetOrCreate.
ManagementActor now drops the central definition cache post-commit (via the existing
AfterConfigurationCommit seam) after every external system, external-system method and
database connection create/update/delete, so an edit takes effect on the editing node
immediately instead of after DefinitionCacheTtl. ManagementService gains a project reference
to ExternalSystemGateway. The other central node still converges within the TTL.
An OperationCanceledException escaping RunAsync after ApplicationStopping has fired
(WindowsServiceLifetime.StopAsync gets a cancelled token after shutdown finished) is a
normal stop. Program.IsGracefulShutdown now routes it to an Information line; any other
exception, or a cancellation with no shutdown requested, still logs Fatal and rethrows.
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.
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.
