Resolves the 35 findings from the 2026-06-01 baseline (commit 26ba1c7),
test-first for every behavioral change. +51 tests (331 -> 382 passing, 0 failed).
- Telemetry-001 (HIGH): RedactionEnricher now honours property removal, so a
redactor that drops a key actually scrubs the secret from the event.
- Auth: LDAP validator ValidateOnStart; API-key verify no longer fails on a
best-effort MarkUsed write or a corrupt scopes column (fail-closed); LDAP cert
validation hook; KeyPrefix persistence aligned; README algorithm corrected.
- Health: Akka checks return Degraded (not throw) when the cluster isn't up yet;
GrpcDependencyHealthCheck catch-all; null 'description' rendered; composite
endpoint builder; XML docs shipped.
- Audit: CompositeAuditWriter no longer re-throws OperationCanceledException;
TruncatingAuditRedactor over-redact scrubs Target + safe negative max; options
record; XML docs shipped.
- Configuration: TryAddEnumerable idempotent registration; consistent port
quoting; strict invariant port parsing; XML docs + README packaged.
- Theme: mobile toggle is now CSS-only (no Bootstrap JS); token/CSS hygiene;
XML docs on the public parameter surface.
Shared-contract/spec docs updated where the code was the source of truth
(observability service.instance.id, MapZbMetrics, redactor reach). All changes
additive/back-compatible at v0.1.0. code-reviews bookkeeping follows separately.
Fix 1 — symmetric OTLP trigger: ZbSerilogConfig.ApplyOpenTelemetryExport now activates only
when options.Exporter == ZbExporter.Otlp, matching the core OTel metrics/traces path. The
previous fallback that also triggered on a bare OtlpEndpoint is removed; OtlpEndpoint is the
address to use when Otlp is selected, not an independent enable.
Fix 2 — deterministic service.instance.id: ZbResource.InstanceId (MachineName:ProcessId) is
a new public property that produces a stable, process-unique id without a random GUID.
ZbResource.Configure passes autoGenerateServiceInstanceId:false + serviceInstanceId:InstanceId
so metrics and traces never get a random auto-generated id. ZbSerilogConfig.BuildResourceAttributes
adds service.instance.id from ZbResource.InstanceId so the Serilog OTLP log sink carries the
exact same value — all three signals now share an identical resource for cross-signal joins.
Tests: +2 in ZbResourceTests (InstanceId determinism, no-GUID check), +2 in RedactionTests
(service.instance.id parity assertion in BuildResourceAttributes, symmetric OTLP trigger tests).
Total: 9 + 14 = 23 tests, all green.
