+# Trust Algebra Panel Angular Components
+
+## Module
+Web
+
+## Status
+IMPLEMENTED
+
+## Description
+Angular component suite for visualizing the VEX trust lattice: TrustAlgebraComponent (main panel), ConfidenceMeterComponent, ClaimTableComponent, PolicyChipsComponent, plus models and service. Distinct from existing features like "Proof Studio UX" or "Evidence Panel UI" -- this is specifically the trust algebra visualization with claim table and policy chip views.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/`
+- **Components**:
+  - `claim-table` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/claim-table.component.ts`)
+  - `confidence-meter` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/confidence-meter.component.ts`)
+  - `policy-chips` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/policy-chips.component.ts`)
+  - `replay-button` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/replay-button.component.ts`)
+  - `trust-algebra` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/trust-algebra.component.ts`)
+  - `trust-vector-bars` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/trust-vector-bars.component.ts`)
+- **Services**:
+  - `trust-algebra` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/trust-algebra.service.ts`)
+- **Models**:
+  - `src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/trust-algebra.models.ts`

+
+## E2E Test Plan
+- **Setup**:
+  - [ ] Log in with a user that has appropriate permissions
+  - [ ] Navigate to the relevant page/section where this feature appears
+  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
+- **Core verification**:
+  - [ ] Verify the panel/drawer opens on trigger (click, keyboard shortcut)
+  - [ ] Verify the panel displays the correct detail data for the selected item
+  - [ ] Verify the panel can be closed (X button, Escape key, backdrop click)
+- **Edge cases**:
+  - [ ] Verify graceful handling when backend API is unavailable (error state)
+  - [ ] Verify responsive layout at different viewport sizes
+  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
