I1 (security): OverRedact() in ScadaBridgeAuditRedactor now suppresses ErrorDetail,
ErrorMessage, and Extra (in addition to RequestSummary/ResponseSummary) to the
over-redacted marker in BOTH code paths (Deserialize+with path and the fallback
new-AuditDetails path). SafeDefaultAuditRedactor catch block aligned to match.
M3 (test): OuterCatch_OptionsThrows_NeverLeaks_AllSensitiveFieldsOverRedacted forces
the outer try/catch → OverRedact path via a ThrowingMonitor that throws from
CurrentValue (the first statement in the try block). Asserts (a) Apply does not
throw, and (b) all five sensitive free-text fields are suppressed to the
over-redacted marker with PayloadTruncated=true.
M1 (consistency): SafeDefaultAuditRedactor now uses AuditRedactionPrimitives
constants (RedactedMarker for line-format header values, OverRedactedEventMarker
for the catch block), eliminating the divergent [REDACTED]/[redacted by ...]
strings. AuditRedactionPrimitives gains OverRedactedEventMarker = RedactorErrorMarker.
SafeDefaultAuditRedactorTests updated from [REDACTED] → <redacted>.
M2 (comment): Added one-line note in TruncateField explaining why the char-count
(result.Length != value.Length) truncation check is sufficient given TruncateUtf8
only ever shortens.
