13 well-bounded test-coverage gaps closed across 11 test projects.
Net +35 regression tests; no production code changes except the
SiteEventLogger src reference unchanged (W3 redacted only test code).
Test additions:
- CLI-022: CommandTreeTests pinned-count assertion bumped 14→16 and
3 InlineData rows added for the audit + bundle command groups.
- Commons-020: new TransportRecordsTests covers BundleManifest /
ExportSelection / ImportPreview / ImportResolution / ImportResult —
ctor + System.Text.Json round-trip + record-equality (14 tests).
- CD-024: SPLIT-RANGE failure-continuation now under
EnsureLookahead_SecondSplitThrows_LoopAborts_FirstBoundaryStillCommitted
(Skippable MS-SQL fixture); production-shape rowversion delete
asserted by DeleteDeploymentRecord_CurrentRowVersion_StubAttachPath_DeleteSucceeds.
- CentralUI-033: new QueryStringDrillInTests with 4 bUnit cases for
Transport + SiteCalls drill-in / query-string handling.
- DM-024: probe actors (ReconcileProbeActor, SerializationProbeActor,
ArtifactProbeActor) refactored from static fields to per-test instances
(Interlocked on counter) — all 31 callers updated; no production
changes required.
- HM-022: real-time PeriodicTimer test flake fixed by replacing
fixed-budget Task.Delay with a RunLoopUntil poll-until-condition
helper (5s/25ms). Production loop untouched.
- InboundAPI-023: new EndpointExtensionsTests covers the
POST /api/{methodName} composition wiring via TestServer (7 cases:
happy path, missing key 401, unknown method 403, invalid JSON 400,
missing param 400, script-throws 500 sanitised, AuditActorItemKey
stash invariant).
- MgmtSvc-021: 6 new ManagementActorTests cover the Transport bundle
handlers (role gate for Export/Preview/Import, unknown-name
ManagementCommandException, blocker-rejection, dedupe last-write-wins).
- SCA-006: SiteCallQueryRequest_StuckOnly_CursorAtNonStuckBoundary_SkipsToNextStuckRow
pins the missing boundary case.
- SEL-023: stress-test `bool stop` promoted to `volatile bool` for
cross-thread visibility under release/JIT.
Verify-only resolutions:
- NS-024: closed by NS-019 (commit ac96b83 deletion of
NotificationDeliveryService + its test file). No edits needed.
- NotifOutbox-008: FallbackMaxRetries/FallbackRetryDelay are private
forward-compat constants returned only when no SMTP-config row exists
(in which case EmailNotificationDeliveryAdapter returns Permanent,
bypassing the values entirely). Marked Resolved with note.
- Transport-010: Overwrite child-collection sync covered by the T-001/
T-002 tests added in commit e3ca9af; per-IP throttle by
BundleUnlockRateLimiterTests; failed-session retention by
BundleSessionStoreTests; T-009 closed structurally via AsyncLocal.
Marked Resolved by reference.
Build clean; all 11 affected test suites green. README regenerated:
33 open (was 46).
Async cancellation hygiene, fire-and-forget observability, retry/shutdown
semantics, and audit-row coverage across 9 modules. Highlights:
Cancellation & lifecycle:
- AuditLog-006: SqliteAuditWriter.Dispose hops to thread pool, escaping the
captured SyncContext that risked sync-over-async deadlock.
- AuditLog-010: SiteAuditTelemetryActor owns a private lifecycle CTS,
threaded through drain paths instead of CancellationToken.None.
- Comm-019: CentralCommunicationActor adds lifecycle CTS for repo calls.
- Host-019: Migration StartupRetry forwards ApplicationStopping so SIGTERM
during the bounded-retry window aborts cleanly.
Cursor / retry / counter correctness:
- AuditLog-004: SiteAuditReconciliationActor's cursor now holds at `since`
when any row's idempotent insert is still being retried (per-EventId
retry counter, MaxPermanentInsertAttempts=5 escape valve with LogCritical
abandon). No more silent abandonment of permanently-failing rows.
- ConfigDB-019: Dropped the catch-and-continue on EnsureLookaheadAsync's
SPLIT loop — by class-doc construction the catch could only mask real
failures and let the next iteration create permanent partition holes.
- HM-017/018: HealthReportSender + CentralHealthReportLoop snapshot
per-interval counters before sending, restore via new
ISiteHealthCollector.AddIntervalCounters on transport failure so counts
aren't silently lost.
Fire-and-forget / shutdown waits:
- InboundAPI-018: AuditWriteMiddleware observes faulted audit-write tasks
via OnlyOnFaulted continuation (Warning log; response unchanged).
- SnF-024: StoreAndForwardService.StopAsync awaits in-flight retry sweep
with a bounded SweepShutdownWaitTimeout (10s).
Leak / refactor:
- Comm-021: SiteStreamGrpcServer.SubscribeInstance wraps Subscribe in its
own try/catch so a throw doesn't leak the relay actor or _activeStreams
entry.
- Comm-022: VERIFIED already-closed by Comm-016's dead-code purge.
- CLI-017: BundleCommands' three subcommands delegate to ExecuteCommandAsync
(auth-failure exit-code contract unified).
Defensive / validation:
- CLI-021: CliConfig.Load wraps file-read/JSON parse so malformed config
prints a warning and returns defaults instead of crashing the CLI.
- Host-022: ParseLevel emits stderr one-shot warning for unrecognised
MinimumLevel instead of silently coercing to Information.
- ESG-019: ExternalSystemClient sets HttpClient.Timeout=Infinite so the
per-call CTS is the sole timeout source (was clipped to 100s by .NET).
- Security-020: New SecurityOptionsValidator (IValidateOptions) rejects
empty LdapServer/LdapSearchBase with ValidateOnStart.
- DM-019: Lifecycle command timeouts now emit DisableTimedOut/EnableTimedOut/
DeleteTimedOut audit entries (mirrors DeployFailed pattern).
Plus reconciled stale per-module Open-findings counters that had drifted
from prior sessions.
20+ new regression tests across 11 test projects; build clean; affected
suites all green. README regenerated: 75 open (was 93).
