SiteAuditRetentionService (site-only IHostedService) ticks PurgeExpiredAsync on
InitialDelay(5m)/PurgeInterval(24h, clamped >=1m), cutoff = UtcNow - RetentionDays.
Registered site-only in AddAuditLogHealthMetricsBridge; options bound from
AuditLog:SiteRetention. Per-tick failures swallowed. Added a test-only
PurgeIntervalOverride (mirrors SiteCallAuditOptions) so the ms-cadence tick test
can bypass the 1-min production clamp. Doc updated. (PLAN-04 Task 3, S1/U2)
Remove project bookkeeping citations from shipped code comments across the
solution: hyphenated task IDs (WP-14, StoreAndForward-025), milestone/task/
issue refs (M3, Task 4, Audit Log #23, #21), Bundle X task-bundle labels,
and C/D/K/S/T phase labels.
Comment text only — no code logic, string/log literals, or XML-doc structure
changed. Genuine descriptions are preserved (only the citation is stripped),
and technical lookalikes are retained (UTF-8, SHA-256, T00:00:00, M365,
UTC-5, pre-C4/pre-C5 schema versions). Flagged by the new CommentChecker
TaskReferenceInComment / TrackingReferenceInComment checks plus targeted
grep passes; full solution builds clean, append-only guard tests pass.
1. Request headers in Extra JSON (AuditWriteMiddleware): adds a `requestHeaders`
object to the existing Extra JSON alongside remoteIp/userAgent; headers whose
names appear in AuditLogOptions.HeaderRedactList (Authorization, X-Api-Key,
Cookie, Set-Cookie by default) are replaced with "<redacted>" using
OrdinalIgnoreCase matching — same policy as ScadaBridgeAuditRedactor.
2. AuditInboundCeilingHits counter: new IAuditInboundCeilingHitsCounter interface
+ NoOpAuditInboundCeilingHitsCounter default; AuditCentralHealthSnapshot
implements the interface (Interlocked field, thread-safe) and exposes
AuditInboundCeilingHits on IAuditCentralHealthSnapshot; AddAuditLog registers
the NoOp default, AddAuditLogCentralMaintenance forwards to the snapshot;
AuditWriteMiddleware accepts the counter as an optional ctor arg and increments
it once per request where either the request or response body hit the cap.
3. Per-method SkipBodyCapture opt-out: adds SkipBodyCapture bool to
PerTargetRedactionOverride; AuditWriteMiddleware consults the per-target
override map at the start of InvokeAsync (before EnableBuffering) and, when
set, skips body read + capture entirely — the audit row still emits with
headers/metadata but null RequestSummary/ResponseSummary; truncation flags
are also cleared so the ceiling-hits counter is not bumped for opted-out methods.
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).
Perf re-baseline (HotPathLatencyTests): empirical p95 on Apple M-series Release
build: 4KB DetailsJson slow path ≈14 µs, small-DetailsJson no-redactors ≈2 µs,
true no-op fast path ≈0 µs. Thresholds updated: 200 µs / 30 µs / 5 µs (≈15×
headroom for contested CI runners). Old thresholds (50 µs / 10 µs) were set for
the pre-C3 typed-field path; canonical JSON parse+rewrite is empirically faster.
Adds a third test (Filter_Apply_NoDetailsJson_FastPath) that asserts same-instance
return on the DetailsJson-null + within-cap fast path. Env-var overrides retained.
CollapseAuditLogToCanonicalMigrationTests (new): three MSSQL-gated [SkippableFact]
tests verifying Action/Category/Outcome projection, NULL Actor, DetailsJson codec
round-trip, and all six persisted computed columns (Kind/Status/SourceSiteId/
ExecutionId/ParentExecutionId) for ApiOutbound, InboundAuthFailure, and Failed-
status rows.
AddAuditLogTableMigrationTests: rename CreatesFiveNamedIndexes →
CreatesNineNamedIndexes; expand coverage from 5 original indexes to all 9 named
non-clustered indexes present after CollapseAuditLogToCanonical (adds
IX_AuditLog_Execution, IX_AuditLog_ParentExecution, IX_AuditLog_Node_Occurred,
UX_AuditLog_EventId).
Dead-cref cleanup: zero references to the deleted IAuditPayloadFilter /
DefaultAuditPayloadFilter / SafeDefaultAuditPayloadFilter types remain in any
.cs file (source or test). 26 occurrences across 13 files replaced with correct
references to IAuditRedactor / ScadaBridgeAuditRedactor / SafeDefaultAuditRedactor
or reworded as plain prose.
Residual sweep: no unused transitional code found beyond the acknowledged
"C3 transitional shim" comments on IngestedAtUtc stamping (active code, not dead).
