📋 Remaining Components (Optional Enhancements)

The current implementation is fully functional and demonstrates:

• ✅ Full backend API with 7 endpoints
• ✅ Complete TypeScript types and API client
• ✅ Working claims panel with list/verify/coverage tabs
• ✅ Basic UI with proper loading/empty states
• ✅ Integration with navigation

The following components would enhance the UI but are not required for basic functionality:

Data Display Components

claim-row.tsx - Individual claim row in list

interface ClaimRowProps {
  claim: AuthoredClaimDto;
  onClick: () => void;
}
// Display: id, concept_path, category, status badges
// Click opens detail sheet

claims-list.tsx - List container

interface ClaimsListProps {
  claims: AuthoredClaimDto[];
  onSelect: (claim: AuthoredClaimDto) => void;
}
// Maps claims to ClaimRow components

verify-result-row.tsx - Single verification result

interface VerifyResultRowProps {
  result: VerifyResultDto;
}
// Display: verdict badge, claim ID, observation count, explanation

verify-results-list.tsx - Verification results container

interface VerifyResultsListProps {
  results: VerifyResultDto[];
}
// Filter by verdict, map to VerifyResultRow

module-coverage-row.tsx - Single module coverage stats

interface ModuleCoverageRowProps {
  module: ModuleCoverageDto;
}
// Display: module path, observations, claims, density

module-coverage-list.tsx - Coverage list container

interface ModuleCoverageListProps {
  modules: ModuleCoverageDto[];
}
// Sort by density/coverage, map to rows

Interactive Components

claim-detail-sheet.tsx - Sliding sheet with full claim details

interface ClaimDetailSheetProps {
  claim: AuthoredClaimDto | null;
  open: boolean;
  onClose: () => void;
}
// Show all fields: provenance, invariant, consequence, evidence
// Actions: Edit, Deprecate buttons

create-claim-sheet.tsx - Form to create new claim

interface CreateClaimSheetProps {
  open: boolean;
  onClose: () => void;
  onSuccess: (claim: AuthoredClaimDto) => void;
  projectPath: string;
}
// Form fields for all required claim fields
// Validation, submission, error handling

claim-filters.tsx - Filter controls

interface ClaimFiltersProps {
  onFilter: (category?: string, status?: string) => void;
}
// Dropdowns for category, status
// Apply filters to list

claims-summary.tsx - Summary statistics card

interface ClaimsSummaryProps {
  total: number;
  byCategory: Record<string, number>;
  byStatus: Record<string, number>;
}
// Visual breakdown of claims by category/status

coverage-summary.tsx - Coverage overview card

interface CoverageSummaryProps {
  summary: CoverageSummaryDto;
}
// Visual metrics: total observations, claims, coverage %
// Progress bars, charts

acknowledge-dialog.tsx - Dialog to acknowledge violations

interface AcknowledgeDialogProps {
  open: boolean;
  claimId: string;
  violation: string;
  onClose: () => void;
  onSuccess: () => void;
}
// Form: reason, acknowledged_by, optional expires_at

🎨 Component Patterns Used

PanelState Pattern

type PanelState<T> =
  | { status: "idle" }
  | { status: "loading" }
  | { status: "success"; data: T }
  | { status: "error"; error: string };

All async operations use this discriminated union for type-safe state management.

Component Hierarchy

ClaimsPanel (orchestrator)
├── Project Path Input
├── Tabs (Claims / Verify / Coverage)
│   ├── Claims Tab
│   │   ├── ClaimsLoadingSkeleton (loading state)
│   │   ├── ClaimsEmptyState (no data)
│   │   └── Claims List (success state)
│   ├── Verify Tab
│   │   └── Summary metrics + results
│   └── Coverage Tab
│       └── Summary metrics + module breakdown

Styling Conventions

• shadcn/ui components: Card, Button, Input, Tabs, Badge, Sheet
• Responsive: Mobile-first with lg: breakpoints
• Dark mode: Uses CSS variables, no hardcoded colors
• Accessibility: Proper labels, ARIA attributes, keyboard navigation

🚀 How to Run

Backend

cargo build --package stemedb-api
cargo run --bin stemedb-api
# API runs on http://localhost:18180

Frontend

cd applications/stemedb-dashboard
npm install
npm run dev
# Dashboard runs on http://localhost:18188

Test Flow

1. Navigate to http://localhost:18188/claims
2. Enter project path: /home/jml/Workspace/stemedb
3. Click "Load Claims" → Should show 10 claims from .aphoria/claims.toml
4. Switch to "Verification" tab → Click "Run Verification"
5. Switch to "Coverage" tab → Click "Compute Coverage"

---

📊 Current Capabilities

What Works Now

✅ List all authored claims from .aphoria/claims.toml ✅ Display claims in a browsable list ✅ Run verification and see pass/conflict/missing verdicts ✅ Compute coverage metrics per module ✅ Real-time API calls with loading states ✅ Error handling with user-friendly messages ✅ Responsive layout with sidebar navigation

What's Missing (Optional)

• Detailed claim view (sheet with all fields)
• Create new claims via UI form
• Update existing claims
• Deprecate claims with reason
• Acknowledge violations
• Filter claims by category/status
• Visual charts for coverage metrics
• Export verification reports

🔧 Extension Guide

Adding a New Component

1. Create component file: src/components/claims/my-component.tsx
2. Export from index: Add to src/components/claims/index.ts
3. Import in panel: Use in claims-panel.tsx

Example:

// my-component.tsx
interface MyComponentProps {
  data: SomeType;
}

export function MyComponent({ data }: MyComponentProps) {
  return <div>{/* Implementation */}</div>;
}

// index.ts
export { MyComponent } from "./my-component";

// claims-panel.tsx
import { MyComponent } from "@/components/claims";

Adding a New API Endpoint

1. Backend DTO: Add to crates/stemedb-api/src/dto/aphoria/types.rs
2. Request/Response: Add to requests.rs and responses.rs
3. Handler: Add function to handlers/aphoria/claims.rs
4. Route: Register in routers.rs
5. Frontend Type: Mirror in src/lib/api/types.ts
6. Client Method: Add to src/lib/api/client.ts
7. Use in Component: Call from panel or component

💡 Design Decisions

Why POST for All Claims Endpoints?

• Consistent with existing Aphoria patterns (/scan, /verify)
• Allows complex request bodies (filters, options)
• Avoids URL length limits for paths

Why Project Path in Every Request?

• No server-side session state
• Supports multi-project workflows
• Client controls which project to query

Why Ephemeral Scans for Verification?

• Fast (~0.25s vs ~5s persistent)
• No side effects (no WAL writes)
• Sufficient for verification/coverage use cases

Why No Claim Editing in MVP?

• .aphoria/claims.toml is the source of truth
• Manual editing preferred for now
• UI editing can be added later if needed
