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).
Add a periodic reconciliation tick to SiteCallAuditActor that, per site,
pulls changed SiteCall rows since a per-site UpdatedAtUtc cursor and upserts
them idempotently (monotonic UpsertAsync) — the documented self-heal for lost
best-effort gRPC telemetry. Mirrors SiteAuditReconciliationActor's structure
(per-site cursor, per-site try/catch failure isolation, advance cursor by max
observed UpdatedAtUtc) minus the stalled-detection EventStream machinery.
Dependency wiring: add an acyclic SiteCallAudit -> AuditLog project reference
and resolve IPullSiteCallsClient + ISiteEnumerator (central-only singletons
registered by AddAuditLogCentralReconciliationClient) from the IServiceProvider
the production ctor already holds — no Host Props.Create change needed. The
repo-only test ctor injects neither collaborator, so the tick is gated off
there. A new public test ctor injects fake client + enumerator + repo so the
tick is unit-testable in-memory (public, not internal: Akka's ActivatorProducer
uses public-only reflection binding).
Options: ReconciliationInterval (default 5 min, clamped >= 1s so a zero config
value can't spin the scheduler) + ReconciliationBatchSize (default 500), plus a
test-only override that bypasses the clamp for millisecond cadences.
Tests (all in-memory, no live MSSQL): absent row is upserted on a tick; second
tick advances the cursor past already-pulled rows; one failing site does not
sink other sites; repo-only ctor does not start the tick.
Site Call Audit (#22): build the documented periodic reconciliation PULL
self-heal path for the eventually-consistent central SiteCalls mirror, as a
dedicated PullSiteCalls gRPC RPC kept separate from the audit pull. This is the
pull PLUMBING only; the central reconciliation tick is a separate follow-up.
- IOperationTrackingStore.ReadChangedSinceAsync(sinceUtc, batchSize): inclusive
UpdatedAtUtc cursor, oldest-first, batch-capped; SQLite impl projects tracking
rows onto SiteCallOperational (Kind->Channel, TargetSummary->Target, SourceSite
left empty - the store has no site-id column).
- sitestream.proto: rpc PullSiteCalls + PullSiteCallsRequest/Response, mirroring
PullAuditEvents; regenerated checked-in SiteStreamGrpc/*.cs.
- SiteCallDtoMapper.ToDto(SiteCallOperational): inverse of FromDto for the handler.
- SiteStreamGrpcServer.PullSiteCalls handler + SetOperationTrackingStore seam;
Host wires the seam alongside SetSiteAuditQueue (site roles only).
- Central IPullSiteCallsClient + GrpcPullSiteCallsClient (home: AuditLog/Central to
reuse ISiteEnumerator; SiteCallAudit does not reference AuditLog). Re-stamps
SourceSite from the dialed siteId; no-throw on tolerable transport faults;
SpecifyKind (not ToUniversalTime) cursor handling. Central-only DI registration.
Tests: ReadChangedSinceAsync (4), PullSiteCalls handler (6), GrpcPullSiteCallsClient
(8). Full solution build 0 warnings/0 errors (TreatWarningsAsErrors).
Add InsertNotificationAsync with explicit status/createdAt parameters so tests
can seed back-dated Retrying rows that satisfy the IsStuck derived property
(Status ∈ {Pending,Retrying} && CreatedAt < now − 10 min). Refactor
InsertParkedNotificationAsync to delegate to it, preserving its exact public
signature and producing identical SQL for existing callers.
