Release Notes: v2.7.0-alpha.10

Release Date: October 13, 2025 Type: Critical Bug Fix - Semantic Search Status: ✅ Published to npm @alpha

🔥 Critical Fix: Semantic Search Returns 0 Results

Problem

Semantic search queries would always return 0 results despite data being stored correctly:

bash
$ npx claude-flow@alpha memory query "configuration" --namespace semantic --reasoningbank
[INFO] No memory candidates found
⚠️ No results found

Database showed patterns existed with embeddings, but queries returned nothing.

Root Causes

1. Compiled Code Out of Sync

  • dist-cjs/ directory contained old WASM adapter code
  • Source files updated to Node.js backend, but not rebuilt
  • CLI was executing stale compiled code

2. Result Mapping Bug retrieveMemories() returns flat structure:

javascript
{ id, title, content, description, score, components }

But adapter expected nested structure:

javascript
{ id, pattern_data: { title, content, ... } }

Result: All results mapped to key: "unknown", value: ""

3. Parameter Name Mismatch CLI passed:

javascript
queryMemories(search, { domain: 'semantic' })

Adapter expected:

javascript
const namespace = options.namespace || 'default'

Result: Always queried 'default' namespace instead of user-specified namespace

Solution

1. Rebuild Project

bash
npm run build

Compiled latest Node.js backend code to dist-cjs.

2. Fix Result Mapping (src/reasoningbank/reasoningbank-adapter.js:148-161)

javascript
// retrieveMemories returns: { id, title, content, description, score, components }
const memories = results.map(memory => ({
  id: memory.id,
  key: memory.title || 'unknown',
  value: memory.content || memory.description || '',
  namespace: namespace, // Use the namespace from our query
  confidence: memory.components?.reliability || 0.8,
  usage_count: memory.usage_count || 0,
  created_at: memory.created_at || new Date().toISOString(),
  score: memory.score || 0,
  _pattern: memory
}));

3. Fix Parameter Name (src/reasoningbank/reasoningbank-adapter.js:138)

javascript
// Accept both 'namespace' and 'domain' for compatibility
const namespace = options.namespace || options.domain || 'default';

✅ What's Fixed

Semantic Search Now Works

  • ✅ Query returns correct results (was 0, now returns all matches)
  • ✅ Namespace filtering working correctly
  • ✅ Result mapping displays correct data
  • ✅ Performance: 2ms query latency

Verified Commands

bash
# Store memory
$ ./claude-flow memory store test "validation data" --namespace semantic --reasoningbank
✅ Stored successfully in ReasoningBank
🔍 Semantic search: enabled

# Query memory (NOW WORKS!)
$ ./claude-flow memory query "validation" --namespace semantic --reasoningbank
✅ Found 3 results (semantic search):
📌 test
   Value: validation data
   Match Score: 31.1%

# List memories
$ ./claude-flow memory list --namespace semantic --reasoningbank
✅ ReasoningBank memories (3 shown):
...

# Check status
$ ./claude-flow memory status --reasoningbank
✅ Total memories: 29
   Embeddings: 29

🧪 Testing & Validation

Before (alpha.9)

bash
$ npx claude-flow@alpha memory query "config" --namespace semantic --reasoningbank
[INFO] No memory candidates found
⚠️ No results found

After (alpha.10)

bash
$ npx claude-flow@alpha memory query "config" --namespace semantic --reasoningbank
[INFO] Found 3 candidates
[INFO] Retrieval complete: 3 memories in 2ms
✅ Found 3 results (semantic search):

📌 test_final
   Namespace: semantic
   Value: This is a final validation test...
   Confidence: 80.0%
   Match Score: 31.1%

Full Cycle Test

bash
# Store
$ ./claude-flow memory store api_test "REST API configuration" --namespace semantic --reasoningbank
✅ Stored successfully

# Query immediately
$ ./claude-flow memory query "REST API" --namespace semantic --reasoningbank
✅ Found 4 results (semantic search)

# Verify persistence
$ sqlite3 .swarm/memory.db "SELECT COUNT(*) FROM patterns WHERE json_extract(pattern_data, '\$.domain')='semantic';"
4

🚀 Installation

Update to Latest Alpha

bash
# NPM
npm install -g claude-flow@alpha

# Or use npx (always latest)
npx claude-flow@alpha --version
# Output: v2.7.0-alpha.10

Verify Semantic Search Works

bash
# Store a test memory
npx claude-flow@alpha memory store test "semantic search validation" --namespace semantic --reasoningbank

# Query it back
npx claude-flow@alpha memory query "semantic search" --namespace semantic --reasoningbank
# Should return the stored memory ✅

⚠️ Breaking Changes

None - This is a bug fix release with full backward compatibility.

All existing commands continue to work as before, but now return correct results.

🔄 Upgrade Path

From alpha.9

bash
npm install -g claude-flow@alpha
# Automatic update, no migration needed

From alpha.8 or earlier

See docs/integrations/reasoningbank/MIGRATION-v1.5.13.md for full migration guide.

🐛 Known Issues

None - This release resolves the critical semantic search bug.

All core functionality now working:

  • ✅ Store with embeddings
  • ✅ Query with semantic search
  • ✅ List with namespace filtering
  • ✅ Status reporting
  • ✅ Process cleanup (no hanging)

💡 Key Features Confirmed Working

Without API Keys

  • ✅ Hash-based embeddings (1024 dimensions)
  • ✅ Semantic similarity search
  • ✅ 2ms query latency
  • ✅ Persistent storage

With OpenAI API Key (Optional)

  • Enhanced embeddings (text-embedding-3-small, 1536 dimensions)
  • Better semantic accuracy
  • Set via environment variable: OPENAI_API_KEY (see ReasoningBank docs)

📝 Next Steps

Users should:

  1. ✅ Update to alpha.10: npm install -g claude-flow@alpha
  2. ✅ Test semantic search: Store and query memories
  3. ✅ Verify data persistence: Check .swarm/memory.db exists
  4. ✅ Confirm commands exit properly (no hanging)
