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.
