+# Triage Workspace with Proof Tree
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Triage workspace experience for artifact-scoped vulnerability triage with integrated proof tree visualization and verify-action workflow.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/triage/`
+- **Primary components**:
+  - `triage-workspace` (`src/Web/StellaOps.Web/src/app/features/triage/triage-workspace.component.ts`)
+  - `proof-tree` (`src/Web/StellaOps.Web/src/app/shared/components/proof-tree.component.ts`)
+- **Storybook coverage**:
+  - `proof-tree.stories` (`src/Web/StellaOps.Web/src/stories/provcache/proof-tree.stories.ts`)
+- **Behavior coverage**:
+  - `src/Web/StellaOps.Web/src/tests/triage/triage-workspace-with-proof-tree.behavior.spec.ts`
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to triage workspace route containing an `artifactId`
+  - [ ] Ensure artifact findings and proof digest test data are available
+- **Core verification**:
+  - [ ] Verify workspace filters findings to the active artifact and keeps deterministic selection
+  - [ ] Verify reachability tab supports textual proof mode rendering
+  - [ ] Verify proof tree verify action emits the current digest payload
+- **Edge cases**:
+  - [ ] Verify degraded API path surfaces non-crashing fallback state
+  - [ ] Verify proof tree renders empty-state behavior when digest/verdict data is absent
+  - [ ] Verify accessibility semantics for tab and tree controls
+
+## Verification
+- Run ID: `docs/qa/feature-checks/runs/web/triage-workspace-with-proof-tree/run-001/`
+- Date (UTC): 2026-02-11
+- Tier 0: PASS (workspace/proof-tree source presence and symbol verification, plus test harness reliability fix to async/whenStable).
+- Tier 1: PASS (`npm run test` focused suite: 22 files / 106 tests; `npm run build` passed with known baseline warnings).
+- Tier 2: PASS (artifact-scoped finding load behavior, reachability textual proof mode flow, and proof-tree verify-action emission).
