The panel runs a plain threaded gunicorn worker and gunicorn is already
in requirements.txt; the extra gevent and gevent-websocket installs were
left over from the old worker class.
Introduce fallback audit logging and enrich audit tooling; add builtin extension discovery/install; and update default launcher ports and related docs/config.
Key changes:
- New middleware app.middleware.audit registers an after-request fallback that records authenticated mutating API requests when routes don't emit explicit audit logs.
- Audit model/action constants extended and AuditService enhanced (request context handling, redaction for sensitive settings, optional commit flag, sets g.audit_logged, emits events).
- Routes/services updated to create explicit audit entries for marketplace and plugin operations (create/update/publish/install/uninstall/enable/disable) and SSO/settings flows switched to use AuditService.
- Added tests for audit logging behavior and redaction (backend/tests/test_audit_log.py).
- Plugin service: added BUILTIN_EXTENSIONS_DIR, list_builtin_extensions and install_builtin_extension; plugin API endpoints to list/install builtin extensions.
- Contribution system extended to support layouts and route layout metadata; frontend wiring updated to surface standalone/custom layouts and extension routes.
- Launcher port defaults changed (backend -> 47927, frontend -> 41921). Updated backend .env.example, config CORS defaults, Dockerfiles and docker-compose to use SERVERKIT_BACKEND_PORT, and many docs/README files and frontend envs to reflect new ports.
- Minor frontend cleanups and new builtin extension example (serverkit-git) plus associated manifest and frontend re-export.
These changes improve observability/security for mutating APIs, enable opt-in builtin plugins, and align local dev/run ports with the launcher defaults.
Introduce a full workflow/automation subsystem: new WorkflowEngine with DAG validation/execution (Kahn's algorithm), logic-if branching, variable interpolation, script sandboxing (timeouts, output limits), retry semantics, notification nodes, and an in-process WorkflowEventBus for event-triggered workflows. Backend API updates include webhook trigger and validate endpoints, auto-generation of webhook IDs on create/update, and services emitting events (git push, health check failures, app stopped, monitoring alerts). Add Alembic migration to create workflow-related tables and bump VERSION to 1.4.0. Also update .gitignore, add GitHub issue/PR templates, quick-start script, and various frontend workflow panel/component adjustments to support the new automation features.
