AuditLogIngestActor and SiteCallAuditActor each exposed constructors taking a scoped
repository and caching it on a field for the actor's lifetime. Safe only because no
production call site picked those overloads — i.e. one call site away from re-introducing
the row-45 captive-dependency bug — which is why CaptiveDependencyGuard had to allowlist
both fields.
Preferred fix applied: the test fixtures fold onto the IServiceProvider overload with a
stub provider, and the constructors are gone.
Product deletions:
- AuditLogIngestActor: the (IAuditLogRepository, ILogger) ctor, the _injectedRepository
field and its branch in OnIngestAsync, and OnCachedTelemetryWithoutDualWriteAsync (the
"this ctor cannot dual-write" fallback handler that only that ctor installed).
_serviceProvider is now non-nullable and the null-forgiving operators are gone.
- SiteCallAuditActor: both test ctors (repo-only, and repo + reconciliation
collaborators), the _injectedRepository field and its four branches, and the private
SerializedRepository class. _backgroundTimersEnabled went with them: only the deleted
repo-only ctor ever set it false, so it was a constant and its two guards are removed.
The reconciliation tick is still gated — on the collaborators being resolvable, which
is how production reaches the same state.
Test fixtures (12 call sites): two small TestSupport helpers build the stub providers.
SiteCallAuditActor's production wiring resolves a FRESH repository per scope, so the
serializing decorator existed only to protect fixtures that share one DbContext-backed
instance across every scope — it moves into the test project as
SerializingSiteCallAuditRepository, which is where the hazard is actually created.
Fixtures that relied on it keep it. The relay test's ICentralAuditWriter now arrives via
the provider, exactly as production resolves it.
Behaviour is preserved on the paths under test: the deleted audit ctor passed
redactor:null / failureCounter:null, and a provider registering neither resolves both to
null, so the SafeDefaultAuditRedactor fallback and counter-free logging are unchanged. No
fixture on the folded sites sends IngestCachedTelemetryCommand, so swapping to the real
dual-write handler is inert. The SiteCallAudit purge timer now arms in fixtures that
previously had timers off, but every one of them uses default purge settings whose first
tick is 5 minutes out — nothing fires inside a test.
One reconciliation test was renamed and rewritten rather than deleted:
TestCtor_RepositoryOnly_DoesNotStartReconciliationTick became
NoReconciliationCollaboratorsRegistered_DoesNotStartReconciliationTick — the same
guarantee, expressed the way production actually reaches it.
Guard: the allowlist is now EMPTY. The staleness self-test (every entry must still match a
flagged field) is replaced by two stronger pins — Allowlist_IsEmpty asserts nothing is
exempt at all, and FormerlyAllowlistedActors_NowScanClean scans both actors with the
allowlist DISABLED, so the empty allowlist is evidence the fields are gone rather than
evidence the scan stopped looking.
Negative control: re-adding an ISiteCallAuditRepository field to SiteCallAuditActor fails
both FormerlyAllowlistedActors_NowScanClean and the real
Central_NoActorHoldsCaptiveScopedState scan.
Verification: solution builds clean. AuditLog.Tests 3/3 (383), SiteCallAudit.Tests 3/3
(66), Host.Tests 2/2 (505), IntegrationTests 2/2 (115), Communication.Tests 2/2 (717).
Reconciliation cursor becomes composite (UpdatedAtUtc, TrackedOperationId);
IPullSiteCallsClient/GrpcPullSiteCallsClient forward the Task-15 after_id keyset
(additive param, null preserves the legacy inclusive >= contract). A burst
sharing one exact UpdatedAtUtc now drains via the id tiebreak instead of pinning
forever. A legacy site that ignores after_id is latched + published as
SiteCallReconciliationPinnedChanged on the EventStream (transition-only),
replacing the prior silent log line.

Highs fixed:
- DeploymentManager-025/SiteRuntime-031: stop broadcasting notification lists + SMTP
configs (incl. credentials) to sites; site purges already-persisted rows on apply
(enforces the central-only delivery design; clears plaintext SMTP creds at rest).
- DataConnectionLayer-023: guard the native-alarm subscribe path against the
mid-flight-unsubscribe adapter-feed leak (mirrors the DCL-021 tag-path fix).
- SiteEventLogging-024: normalize From/To query bounds to UTC (the -016 fix the
audit trail claimed but never committed).
- KpiHistory-001: add an in-flight guard to the recorder sample tick.
- ScriptAnalysis-001: harden the trust analyzer's TPA-absent fallback (resolve
forbidden anchors in the minimal reference set; warn on degraded mode) — anchors
added to validation references only, never the compile gate.
(InboundAPI-026 left to the feat/ipsen-movein effort per owner decision.)

Add a daily purge tick to SiteCallAuditActor that drops terminal SiteCalls
rows older than the retention window via ISiteCallAuditRepository.PurgeTerminalAsync.
The threshold is computed each tick as UtcNow - RetentionDays so an operator who
lowers RetentionDays sees it on the next purge without a restart. Mirrors
AuditLogPurgeActor's daily cadence + continue-on-error posture: a purge fault is
logged and swallowed so the central singleton stays alive and retries next tick.
The purge timer is started in PreStart alongside the reconciliation timer and
gates on the same collaborators (pull client + enumerator) being available — the
repo-only test ctor injects neither, so neither background timer runs there.
Options: PurgeInterval (default 24h, clamped >= 1 min so a zero config value
can't spin the scheduler) + RetentionDays (default 365), plus a test-only
override that bypasses the clamp for millisecond cadences.
Tests (all in-memory, no live MSSQL): purge tick calls PurgeTerminalAsync with a
UtcNow - RetentionDays threshold (non-default 30 days); default retention yields
a 365-day threshold; a throwing repo does not kill the singleton (a second tick
still arrives).
