# 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.

## Recheck (run-006)
- Date (UTC): 2026-02-11
- Status: VERIFIED (strict Tier 2 UI replay)
- Tier 1 evidence: Targeted quiet-triage suite passed 10/10 across 3 files.

- Replay scope:
  - Navigate to `/triage/quiet-lane` and verify lane toggle shell.
  - Exercise blocked parked-item promote flow and confirm Tier 3 VEX evidence sheet behavior.
  - Validate keyboard lane switching (`A` / `P` / `R`) and parked action events.
  - Validate provenance breadcrumb actions (attestation/SBOM/package navigation event paths).
