# Trust Algebra Panel Angular Components
## Module
Web
## Status
VERIFIED
## 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-algebra-workbench` (`src/Web/StellaOps.Web/src/app/features/vulnerabilities/components/trust-algebra/trust-algebra-workbench.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`
- **Route surface**:
- `/policy/trust-algebra` (`src/Web/StellaOps.Web/src/app/features/policy/policy.routes.ts`)
- **Behavior coverage**:
- `src/Web/StellaOps.Web/src/tests/vulnerabilities/trust-algebra-panel-angular-components.behavior.spec.ts`
- **Source**: SPRINT_7100_0003_0001_ui_trust_algebra.md
## E2E Test Plan
- **Setup**:
- [ ] Log in with a user that has appropriate permissions
- [ ] Navigate to `/policy/trust-algebra`
- [ ] Ensure trust-manifest fixture data is available to the panel
- **Core verification**:
- [ ] Verify trust algebra workbench renders panel and replay mode toggle
- [ ] Verify accepted claim drives trust-vector summary and section toggles remain deterministic
- [ ] Verify policy chips are read-only when replay mode is active and interactive otherwise
- **Edge cases**:
- [ ] Verify claim table tie ordering remains deterministic when scores are equal
- [ ] Verify row interaction emits claim selection events
- [ ] Verify route declaration remains present in policy routes
## Verification
- Run ID: `docs/qa/feature-checks/runs/web/trust-algebra-panel-angular-components/run-001/`
- Date (UTC): 2026-02-11
- Tier 0: PASS (source/symbol verification for trust algebra components, route wiring, and behavior harness).
- Tier 1: PASS (`npm run test` focused suite: 23 files / 114 tests; `npm run build` passed with known baseline warnings).
- Tier 2: PASS (route/workbench exposure, deterministic trust-vector + claim ordering semantics, replay-mode read-only policy actions, and claim selection interactions).
