# Aphoria Dashboard Integration Status
> **Date**: 2026-02-08
> **Phase CC Complete**: All community corpus features integrated ✅

---

## ✅ What's Integrated

### 1. **API Endpoint** ✅
**File**: `crates/stemedb-api/src/handlers/aphoria/report.rs:232`

```rust
pub async fn get_patterns(
    State(state): State<AppState>,
    Query(params): Query<GetPatternsRequest>,
) -> Result<Json<GetPatternsResponse>> {
    // ✅ Uses GenericPatternAggregateStore (new infrastructure)
    let pattern_store = GenericPatternAggregateStore::new(state.store.clone());

    // ✅ Queries pattern aggregates from StemeDB
    let aggregates = if let Some(prefix) = &params.subject_prefix {
        pattern_store.get_patterns_for_subject_prefix(...)
    } else {
        pattern_store.get_popular_patterns(...)
    };

    // ✅ Uses PatternEnricher for query-time enrichment
    let enricher = PatternEnricher::from_registry(&registry);
}
```

**Endpoint**: `GET /v1/aphoria/patterns`

**Features**:
- ✅ Queries pattern aggregates from StemeDB (not flat files)
- ✅ Filters by `subject_prefix` (e.g., "tls/cert")
- ✅ Filters by `min_projects` threshold
- ✅ Query-time enrichment (category, verdict, explanation)
- ✅ Authority source matching

---

### 2. **Dashboard UI** ✅
**File**: `applications/aphoria-dashboard/src/app/corpus/page.tsx`

```tsx
export default function CorpusPage() {
  return (
    <>
      <Header title="Community Corpus" />
      <CorpusPanel />
    </>
  );
}
```

**Components**:
- ✅ `CorpusPanel` - Main corpus view with filters
- ✅ `CorpusFilters` - Subject prefix, min projects, category, hide noise
- ✅ `CorpusList` - Pattern cards with enrichment data
- ✅ `CorpusRow` - Individual pattern display
- ✅ Empty states, loading skeletons, error handling

**URL**: `http://aphoria.local/corpus` or `http://localhost:3000/corpus`

---

### 3. **API Client** ✅
**File**: `applications/aphoria-dashboard/src/lib/api/client.ts:191`

```typescript
async getPatterns(params: {
  subjectPrefix?: string;
  minProjects?: number;
  limit?: number;
} = {}): Promise<GetPatternsResponse> {
  const searchParams = new URLSearchParams();
  if (params.subjectPrefix) searchParams.set("subject_prefix", params.subjectPrefix);
  if (params.minProjects !== undefined) searchParams.set("min_projects", String(params.minProjects));
  if (params.limit !== undefined) searchParams.set("limit", String(params.limit));
  return this.fetch<GetPatternsResponse>(`/v1/aphoria/patterns?${searchParams}`);
}
```

**Integration**:
- ✅ Calls `/v1/aphoria/patterns` endpoint
- ✅ Supports filtering by subject prefix, min projects, limit
- ✅ Returns typed `GetPatternsResponse` with pattern DTOs
- ✅ Error handling (404 → empty patterns, other → error state)

---

### 4. **Pattern Enrichment** ✅

The dashboard shows enriched pattern data:
- ✅ **Category badge** - Security, Performance, Configuration, etc.
- ✅ **Verdict badge** - Best Practice, Noise, Neutral
- ✅ **Explanation** - Why this pattern matters
- ✅ **Authority source** - RFC, OWASP references
- ✅ **Project count** - How many projects use this pattern
- ✅ **Observation count** - Total observations across projects

All enrichment happens via the `PatternEnricher` at query time or write time.

---

## 🔄 Data Flow (End-to-End)

```
1. User scans project
   └─> aphoria scan --persist --sync

2. Observations recorded
   └─> Stored as Tier 4 assertions in StemeDB

3. Pattern aggregation (CC.6)
   └─> Observations grouped by (subject, predicate, value)
   └─> Pattern aggregates created/updated in StemeDB
   └─> Stored as assertions with predicate "pattern_aggregate"

4. Community corpus (CC.7)
   └─> CommunityCorpusBuilder queries pattern aggregates
   └─> Promotion thresholds evaluated
   └─> High-confidence patterns promoted to corpus

5. Dashboard queries patterns
   └─> GET /v1/aphoria/patterns
   └─> GenericPatternAggregateStore.get_popular_patterns()
   └─> Returns pattern aggregates from StemeDB

6. UI displays enriched patterns
   └─> CorpusPanel renders patterns with enrichment
   └─> Shows category, verdict, explanation, project count
```

## ✅ Integration Verification

### Test 1: API Endpoint Works
```bash
# Start API server
cargo run --bin stemedb-api

# Query patterns (should return JSON)
curl http://localhost:18180/v1/aphoria/patterns | jq
```

**Expected**:
```json
{
  "patterns": [
    {
      "subject": "code://*/tls/cert_verification",
      "predicate": "enabled",
      "value_display": "true",
      "project_count": 5,
      "observation_count": 12,
      "category": "security",
      "verdict": "best_practice",
      "explanation": "TLS certificate verification prevents MITM attacks"
    }
  ],
  "total_matching": 1
}
```

### Test 2: Dashboard Displays Patterns
```bash
# Start dashboard
cd applications/aphoria-dashboard
npm run dev

# Open in browser
open http://localhost:3000/corpus
```

**Expected**:
- Corpus page loads
- Patterns displayed if available
- Filters work (subject prefix, min projects)
- Empty state shown if no patterns

### Test 3: Pattern Aggregation Works
```bash
# Scan a project to create observations
aphoria scan --persist --sync /path/to/project

# Verify pattern aggregates created
RUST_LOG=aphoria=debug aphoria scan --persist . 2>&1 | grep "pattern_aggregate\|patterns created\|patterns updated"
```

**Expected**:
```
✅ Pattern aggregation: 5 patterns created/updated
✅ Patterns stored with predicate "pattern_aggregate"
```

---

## ⚠️ Known Gaps (If Any)

### Gap 1: No Real-Time Updates
**Status**: Not a blocker

The dashboard doesn't auto-refresh when new patterns are added. User must manually refresh the page.

**Solution** (optional): Add polling or WebSocket support for live updates.

### Gap 2: Hosted Mode vs Community Corpus
**Status**: Documented in CORPUS_STATUS.md

Two separate features that were initially conflated:
- **Hosted Mode**: `/v1/aphoria/observations` - team server
- **Community Corpus**: `/v1/aphoria/community/observations` - public patterns

**Current State**: API serves patterns from StemeDB pattern aggregates created during local scans. Hosted mode integration is separate.

---

## ✅ Summary: Integration Complete

| Component | Status | Notes |
|-----------|--------|-------|
| **Pattern Aggregation** | ✅ Complete | CC.6 - observations → aggregates |
| **Community Corpus Builder** | ✅ Complete | CC.7 - async, enabled by default |
| **Pattern Store API** | ✅ Complete | GenericPatternAggregateStore |
| **API Endpoint** | ✅ Complete | GET /v1/aphoria/patterns |
| **Dashboard UI** | ✅ Complete | /corpus page with filters |
| **API Client** | ✅ Complete | getPatterns() method |
| **Pattern Enrichment** | ✅ Complete | Query-time via PatternEnricher |
| **Empty States** | ✅ Complete | Handles zero patterns gracefully |
| **Error Handling** | ✅ Complete | 404 → empty, other → error |

## 🎯 What's Working Right Now

1. **Local Scans** → Pattern aggregates stored in StemeDB
2. **API Endpoint** → Queries pattern aggregates from StemeDB
3. **Dashboard** → Displays patterns with enrichment
4. **Filters** → Subject prefix, min projects, category
5. **Empty State** → Shown when no patterns exist

---

## 🚀 Next Steps (Optional Enhancements)

### Enhancement 1: Pattern Promotion UI
Add UI for reviewing and promoting patterns that meet thresholds:
- Show promotion candidates (50+ projects, not yet promoted)
- Manual approve/reject buttons
- Maps to Phase 14 (Governance Workflows)

### Enhancement 2: Pattern Timeline
Show how patterns evolve over time:
- Graph of project_count over time
- When pattern first appeared
- Adoption trend (growing/declining)

### Enhancement 3: Pattern Details Page
Click pattern → see:
- All projects using this pattern
- Code examples
- Related patterns
- Authority sources (RFC sections, OWASP references)
