Phase 02: Merge PR #820 - Health Check Endpoint Fix

PR: https://github.com/thedotmack/claude-mem/pull/820 Branch: fix/health-check-endpoint-811 Status: Has conflicts, needs rebase Review: Approved by bayanoj330-dev Priority: HIGH - Fixes 15-second timeout issue affecting all users

Summary

Fixes the "Worker did not become ready within 15 seconds" timeout issue by changing health check functions from /api/readiness to /api/health.

Root Cause: isWorkerHealthy() and waitForHealth() were using /api/readiness which returns 503 until full initialization completes (including MCP connection which can take 5+ minutes). Hooks only have 15 seconds timeout.

Solution: Use /api/health (liveness check) which returns 200 as soon as HTTP server is listening.

Files Changed

File	Change
src/shared/worker-utils.ts	Change /api/readiness → /api/health in isWorkerHealthy()
src/services/infrastructure/HealthMonitor.ts	Change /api/readiness → /api/health in waitForHealth()
tests/infrastructure/health-monitor.test.ts	Update test to expect /api/health

Dependencies

• None - Independent fix

Fixes Issues

• #811
• #772
• #729

Tasks

• Checkout PR branch fix/health-check-endpoint-811 and rebase onto main to resolve conflicts (Completed: Rebased successfully - build artifact conflicts resolved by accepting main and will rebuild)
• Review the endpoint change logic in worker-utils.ts and HealthMonitor.ts (Completed: Logic is sound - both files use /api/health with proper JSDoc explaining the liveness vs readiness distinction)
• Verify build succeeds after rebase (Completed: Build succeeded - all hooks, worker service, MCP server, context generator, and React viewer built successfully)
• Run health monitor tests: npm test -- tests/infrastructure/health-monitor.test.ts (Completed: All 14 tests pass with 24 expect() calls)
• Merge PR #820 to main (Completed: Fast-forward merge from fix/health-check-endpoint-811 to main, pushed to origin)
• Manual verification: Kill worker and start fresh session - should not see 15-second timeout (Completed: Worker health endpoint responds in ~12ms, no timeout errors in logs, both worker-utils.ts and HealthMonitor.ts correctly use /api/health)

Verification

# After merge, verify hooks work during MCP initialization
# Start a fresh session and observe logs
tail -f ~/.claude-mem/logs/worker.log | grep -i "health"

Notes

• This is a quick fix with minimal code changes
• The /api/health endpoint returns 200 as soon as Express is listening
• Background initialization continues after health check passes
• Related to PR #774 which had the same fix but has merge conflicts
