  strategy: 'validation',
  success_score: 0.95
});
```
- **Result**: Pattern stored successfully

**Semantic Search Test**:
```javascript
const similar = await rb.findSimilar('test validation', 'docker-test', 5);
```
- **Results**: 1 similar pattern found ✅
- **Similarity Score**: 0.5314 (53.14% match)
- **Score Range**: Valid (0.3 - 1.0)

**Key Findings**:
- WASM module loads correctly with `--experimental-wasm-modules` flag
- In-memory storage functions as expected
- Embeddings auto-generated ✅
- Semantic similarity scoring works ✅
- Storage is ephemeral (as documented)

### Test 5: Package Exports (1/1 passed)

**Objective**: Verify all ReasoningBank export paths resolve correctly

```javascript
// Conditional export (auto-selects Node.js in Node.js environment)
import * as reasoningbank from 'agentic-flow/reasoningbank';

// Explicit backend selector
import * as selector from 'agentic-flow/reasoningbank/backend-selector';

// Explicit WASM adapter
import * as wasm from 'agentic-flow/reasoningbank/wasm-adapter';
```

**Results**:
- ✅ `agentic-flow/reasoningbank` export works
  - Auto-selected Node.js backend (correct)
  - `db` module present ✅

- ✅ `agentic-flow/reasoningbank/backend-selector` export works
  - `createOptimalReasoningBank` function present ✅
  - `getRecommendedBackend` function present ✅

- ✅ `agentic-flow/reasoningbank/wasm-adapter` export works
  - `createReasoningBank` function present ✅
  - `ReasoningBankAdapter` class present ✅

**Key Findings**:
- Conditional exports work correctly (Node.js vs Browser)
- All export paths resolve
- Function signatures correct
- Type exports available

## 🔧 Technical Environment

### Docker Configuration

**Base Image**: `node:20-slim`
**Node.js Version**: 20.19.5
**Architecture**: linux/amd64
**OS**: Debian 12 (bookworm)

**Installed Packages**:
- git 2.39.5
- curl 7.88.1
- ca-certificates

### Package Installation

**Method**: Local tarball (`npm pack`)
**Source**: `agentic-flow-1.5.13.tgz`
**Installation Time**: 15.2s
**Total Size**: 45.3 MB (unpacked)

### Node.js Flags

**Required for WASM**:
```bash
node --experimental-wasm-modules script.mjs
```

**Why**: Node.js requires experimental flag for `.wasm` imports in ESM context

   - **Reason**: ESM import of `.wasm` files
   - **Impact**: Documentation needed
   - **Workaround**: Documented in README

2. **WASM In-Memory in Node.js**
   - **Behavior**: Storage is ephemeral
   - **Reason**: By design (browser-optimized)
   - **Impact**: Data lost on process exit
   - **Solution**: Use Node.js backend for persistence

3. **Main Export Requires Claude Code**
   - **Test**: Skipped in Docker
   - **Reason**: Requires Claude Code binary
   - **Impact**: None for ReasoningBank
   - **Valid**: Expected behavior
