+# Triage Inbox Angular Component (3-Pane Layout)
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Three-pane Angular triage inbox UI for exploit-path review: left pane path list with risk metadata and filters, center pane path details (package, symbol, entry point, CVEs, risk), and right pane evidence items.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/triage-inbox/`
+- **Components**:
+  - `triage-inbox` (`src/Web/StellaOps.Web/src/app/features/triage-inbox/triage-inbox.component.ts`)
+  - Template (`src/Web/StellaOps.Web/src/app/features/triage-inbox/triage-inbox.component.html`)
+  - Styles (`src/Web/StellaOps.Web/src/app/features/triage-inbox/triage-inbox.component.scss`)
+- **API/Models**:
+  - `triage-inbox client` (`src/Web/StellaOps.Web/src/app/core/api/triage-inbox.client.ts`)
+  - `triage-inbox models` (`src/Web/StellaOps.Web/src/app/core/api/triage-inbox.models.ts`)
+- **Routing**:
+  - `/triage/inbox` route wiring in `src/Web/StellaOps.Web/src/app/app.routes.ts`
+- **Behavior coverage**:
+  - `src/Web/StellaOps.Web/src/tests/triage/triage-inbox-angular-component.behavior.spec.ts`
+- **Source**: `SPRINT_3900_0003_0001_exploit_path_inbox_proof_bundles` (implementation and dossier references normalized during QA verification)
+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to `/triage/inbox` (or embedded inbox host)
+  - [ ] Ensure exploit-path inbox data exists for test artifact digest
+- **Core verification**:
+  - [ ] Verify path list loads and highest-risk entries sort deterministically
+  - [ ] Verify selecting/filtering paths updates center/right panes consistently
+  - [ ] Verify risk/reachability badges and evidence metadata render correctly
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify empty/filtered results clear selection deterministically
+  - [ ] Verify accessibility semantics for path list and detail region updates
+
+## Verification
+- Run ID: `docs/qa/feature-checks/runs/web/triage-inbox-angular-component/run-001/`
+- Date (UTC): 2026-02-11
+- Tier 0: PASS (source/symbol verification for triage inbox component, API models/client, route wiring, and behavior spec).
+- Tier 1: PASS (`npm run test` focused suite: 20 files / 98 tests; `npm run build` passed with known baseline warnings).
+- Tier 2: PASS (behavioral verification of deterministic path ordering/selection, filter transitions, degraded API error path handling, and route-level user surface wiring).
