+# Quiet-by-Default Triage UX (Lane Toggle + Provenance Breadcrumbs)
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Triage UX implements Active/Parked/Review lanes, deterministic gating summaries, and provenance breadcrumb surfaces with keyboard shortcuts for rapid lane switching.
+
+## Implementation Details
+- **Components**:
+  - `src/Web/StellaOps.Web/src/app/features/triage/components/triage-lane-toggle/triage-lane-toggle.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/triage/components/quiet-lane/quiet-lane-container.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/triage/components/quiet-lane/parked-item-card.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/triage/components/provenance-breadcrumb/provenance-breadcrumb.component.ts`
+- **Focused tests**:
+  - `src/Web/StellaOps.Web/src/tests/triage_quiet_lane/triage-lane-toggle.component.spec.ts`
+  - `src/Web/StellaOps.Web/src/tests/triage_quiet_lane/quiet-lane-container.component.spec.ts`
+  - `src/Web/StellaOps.Web/src/tests/triage_quiet_lane/parked-item-card.component.spec.ts`
+
+## Follow-up Notes
+- Tier 2 evidence is component/integration harness-based because the quiet-lane surfaces are not fully mounted behind a stable route in the local shell.
