Known Limitations & Future Work

Current Limitations (47 TODOs)

  1. Mock implementations used for ecosystem crate operations
  2. Webhook handlers log events but don't execute workflows
  3. Daemon management features are stubs
  4. No persistent event storage

Future Enhancements

  1. Replace mock implementations with actual ecosystem crates
  2. Implement webhook workflow execution
  3. Add background daemon startup (systemd/nix)
  4. Add graceful shutdown endpoint
  5. Add configuration reload capability
  6. Track actual uptime
  7. Persistent event storage (SQLite)
