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).
