## 2. Retrieval Algorithm Validation

### Test Setup

**Test Script**: `src/reasoningbank/test-retrieval.ts`

**Test Data**: 5 synthetic memories across 3 domains (test.web, test.api, test.db)

### Retrieval Results

**Query 1**: "How to handle CSRF tokens in web forms?" (domain: test.web)
```
Retrieved 6 candidates:
  1. CSRF Token Handling (conf: 0.88, age: 0d)
  2. Authentication Cookie Validation (conf: 0.82, age: 0d)
  3. Form Validation Before Submit (conf: 0.75, age: 0d)
```

**Query 2**: "API rate limiting and retry strategies" (domain: test.api)
```
Retrieved 2 candidates:
  1. API Rate Limiting Backoff (conf: 0.91, age: 0d)
```

**Query 3**: "Database error recovery" (domain: test.db)
```
Retrieved 2 candidates:
  1. Database Transaction Retry Logic (conf: 0.86, age: 0d)
```

### Scoring Algorithm Verification

**Formula**: `score = α·sim + β·recency + γ·reliability`

**Parameters** (from config):
- α = 0.65 (semantic similarity weight)
- β = 0.15 (recency weight via exponential decay)
- γ = 0.20 (reliability weight from confidence × usage)
- δ = 0.10 (diversity penalty for MMR selection)

**Recency Decay**: `exp(-age_days / 45)` with 45-day half-life

**Reliability**: `min(confidence, 1.0)` bounded by confidence score

### Cosine Similarity Test

```
Cosine similarity (identical vectors): 1.0000
Cosine similarity (different vectors): 0.0015
   ✅ Identical vectors have similarity ≈ 1.0
   ✅ Different vectors have lower similarity
```

**Implementation**: Normalized dot product with magnitude calculation

## 5. Integration Points

### Claude Flow Memory Space

**Database Path**: `.swarm/memory.db`

**Integration Strategy**:
- ✅ Extends existing `patterns` table with `type='reasoning_memory'`
- ✅ No breaking changes to existing memory system
- ✅ Shares `performance_metrics` table for unified observability
- ✅ Compatible with existing session state and namespace features

### Hooks Integration (Not Yet Implemented)

**Pre-Task Hook** (`hooks/pre-task.ts` - to be implemented):
1. Retrieve top-k relevant memories for task query
2. Inject memories into system prompt
3. Log retrieval metrics

**Post-Task Hook** (`hooks/post-task.ts` - to be implemented):
1. Capture trajectory from agent execution
2. Judge trajectory (Success/Failure)
3. Distill new memories from trajectory
4. Check consolidation trigger threshold
5. Run consolidation if needed

**Configuration**: Add to `.claude/settings.json`:
```json
{
  "hooks": {
    "preTaskHook": {
      "command": "tsx",
      "args": ["src/reasoningbank/hooks/pre-task.ts", "--task-id", "$TASK_ID", "--query", "$QUERY"],
      "alwaysRun": true
    },
    "postTaskHook": {
      "command": "tsx",
      "args": ["src/reasoningbank/hooks/post-task.ts", "--task-id", "$TASK_ID"],
      "alwaysRun": true
    }
  }
}
```

   - Parse verdict and store in `task_trajectories`

2. **`core/distill.ts`** - Memory extraction
   - Load templates from `prompts/distill-*.json`
   - Call Anthropic API with trajectory + verdict
   - Extract 1-3 memories per trajectory
   - Store with confidence priors

3. **`core/consolidate.ts`** - Deduplication and pruning
   - Detect duplicates via cosine similarity > 0.87

   - Log consolidation run metrics

4. **`core/matts.ts`** - Memory-aware Test-Time Scaling
   - **Parallel mode**: k independent rollouts with self-contrast
   - **Sequential mode**: r iterative refinements
   - Aggregate high-confidence patterns
   - Boost confidence based on cross-trajectory evidence

5. **`hooks/pre-task.ts`** - Pre-task memory retrieval
   - Call `retrieveMemories(query, { k, domain, agent })`
   - Format memories as markdown
   - Inject into system prompt via stdout
   - Log retrieval metrics

6. **`hooks/post-task.ts`** - Post-task learning
   - Capture trajectory from agent execution
   - Call `judge(trajectory, query)`
   - Call `distill(trajectory, verdict)`
   - Check `countNewMemoriesSinceConsolidation()`
   - If threshold reached, call `consolidate()`

### Implementation Effort

- **Estimated time**: 4-6 hours for experienced developer
- **Complexity**: Medium (requires Anthropic API integration)
- **Dependencies**: All infrastructure in place (DB, config, prompts)

## 9. Security and Compliance

### PII Scrubbing (Configured, Not Implemented)

**Redaction Patterns** (from config):
- Email addresses: `\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b`
- SSN: `\b(?:\d{3}-\d{2}-\d{4}|\d{9})\b`
- API keys: `\b(?:sk-[a-zA-Z0-9]{48}|ghp_[a-zA-Z0-9]{36})\b`
- Slack tokens: `\b(?:xoxb-[a-zA-Z0-9\-]+)\b`
- Credit cards: `\b(?:\d{13,19})\b`

**Status**: Patterns defined, scrubbing logic to be implemented in `utils/pii-scrubber.ts`

### Multi-Tenant Support

**Status**: Schema includes `tenant_id` column (nullable)
**Configuration**: `governance.tenant_scoped = false` (disabled by default)
**To Enable**: Set flag to `true` and add tenant_id to all queries

### Audit Trail

**Configuration**: `governance.audit_trail = true`
**Storage**: All memory operations logged to `performance_metrics` table
**Metrics**: `rb.memory.upsert`, `rb.memory.retrieve`, `rb.memory.delete`
