fix(hooks): V3 MCP hook handlers now persist data to database

[ahmedibrahim085]

Summary

V3 MCP hook handlers (hooksPostEdit, hooksPostTask, hooksPostCommand) were returning success responses but not actually persisting any data. This PR fixes them to call getRealStoreFunction() and store to the database with HNSW indexing.

Problem Evidence

Before (Stub Handlers)

hooksPostEdit (lines 621-645):

return {
  recorded: true,  // ← LIES - nothing was recorded
  ...
};

hooksPostTask (lines 1049-1080):

return {
  duration: Math.floor(Math.random() * 300) + 60, // ← FAKE random data
  learningUpdates: {
    patternsUpdated: success ? 2 : 1,             // ← FAKE - nothing updated
  },
};

Statusline (hooks.ts:3314-3318):

patterns = Math.floor(sizeKB / 2);  // ← FAKE: just file_size / 2KB!

Database Reality:

sqlite3 .swarm/memory.db "SELECT COUNT(*) FROM patterns"
-- Result: 0 (despite statusline showing 1888)

Solution

Updated handlers to call getRealStoreFunction() (which already exists at line 50-60):

Handler	Before	After
hooksPostEdit	Returned {recorded: true}	Stores to patterns namespace with HNSW
hooksPostTask	Returned fake random data	Stores to trajectories namespace with HNSW
hooksPostCommand	Returned {recorded: true}	Stores to commands namespace with HNSW
getLearningStats	file_size / 2KB	Real SELECT COUNT(*) queries

Test Results

✅ post-edit: PERSISTED - "Pattern stored with HNSW indexing"
✅ post-task: PERSISTED - "Trajectory stored with HNSW indexing"  
✅ post-command: PERSISTED - "Command pattern stored with HNSW indexing"

Database verification after fix:

sqlite3 .swarm/memory.db "SELECT namespace, COUNT(*) FROM memory_entries GROUP BY namespace"
-- patterns|1
-- trajectories|1
-- commands|1

Files Changed

File	Changes
v3/@claude-flow/cli/src/mcp-tools/hooks-tools.ts	+131 lines - Fixed 3 handlers
v3/@claude-flow/cli/src/commands/hooks.ts	+42 lines - Fixed statusline

Impact

• Pattern learning works: Edit patterns now persist for cross-session learning
• Trajectory tracking works: Task outcomes stored for routing optimization
• Command history tracked: Commands and success/failure persisted
• Honest metrics: Statusline shows real data instead of fake calculations

Independent Verification Results

I independently discovered the same issues and can confirm this PR fixes them. Here are my findings:

Problem Verified

CLI trajectory commands fail with MCP error:

[ERROR] Intelligence error: Failed to execute MCP tool 'hooks_intelligence': Cannot convert undefined or null to object

But MCP tools work when called directly from Claude Code:

{
  "trajectoryId": "traj-xxx",
  "status": "recording",
  "implementation": "real-trajectory-tracking"
}

Current Workaround (Partial)

The memory store CLI command works, so hooks using cf_memory_store_gate successfully store data:

Namespace	Entries	Searchable
patterns	5	✅ Score 0.41
trajectories	3	✅ Score 0.46
commands	1	✅ Score 0.33

However, SONA learning and EWC++ consolidation don't trigger because hooksPostEdit, hooksPostTask, hooksPostCommand return fake success without calling getRealStoreFunction().

Tested Components

Component	CLI (npx)	MCP (direct)
hooks intelligence trajectory-start	❌ Fails	✅ Works
hooks intelligence trajectory-step	❌ Fails	✅ Works
hooks intelligence trajectory-end	❌ Fails	✅ Works
hooks intelligence --showStatus	❌ Fails	N/A
memory store	✅ Works	✅ Works
memory search	✅ Works	✅ Works

Request

This fix would enable proper learning for users running hooks via bash scripts. The getRealStoreFunction() already exists at line 23 and works - just needs to be called in the stub handlers.

Would appreciate expedited review as this affects all hook-based learning workflows.
