Fix: SessionStart Hook "startup hook error" — Worker Not Waiting

Root Cause

The installed plugin (~/.claude/plugins/marketplaces/thedotmack/) is version 10.2.5 and has none of the recent fixes:

Fix	Repo Status	Installed Status
Hook group split (smart-install isolated from worker start)	In plugin/hooks/hooks.json	Missing — all 3 hooks in one group, smart-install failure blocks worker
waitForReadiness() after spawn	In src/services/infrastructure/HealthMonitor.ts	Missing — 0 occurrences in installed worker-service.cjs
Early initializationCompleteFlag (after DB+search, not MCP)	In src/services/worker-service.ts	Missing — flag set after MCP connection (5+ minute wait)

The changes exist in source code but were never built and synced to the installed location.

Phase 1: Build and Sync

npm run build-and-sync

Verification

# 1. Confirm waitForReadiness exists in installed build
grep -c "waitForReadiness" ~/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs
# Expected: > 0

# 2. Confirm hooks.json has two SessionStart groups (the split)
python3 -c "import json; d=json.load(open('$(echo $HOME)/.claude/plugins/marketplaces/thedotmack/plugin/hooks/hooks.json')); print('SessionStart groups:', len(d['hooks']['SessionStart']))"
# Expected: 2

# 3. Confirm initializationCompleteFlag is set before MCP connection
grep -n "Core initialization complete" ~/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs | head -1
# Expected: appears BEFORE "MCP server connected"

Phase 2: Restart Worker and Test

# Stop existing worker
bun plugin/scripts/worker-service.cjs stop

# Verify stopped
curl -s http://127.0.0.1:37777/api/health && echo "STILL RUNNING" || echo "STOPPED"

Then start a new Claude Code session and verify:

• No "SessionStart:startup hook error" messages
• Worker is running: curl http://127.0.0.1:37777/api/health
• Readiness endpoint works: curl http://127.0.0.1:37777/api/readiness
