_introspect

Built-in/_pounce/infointrospection endpoint (Sprint 5).

Disabled by default. WhenServerConfig.introspection_enabledis True, the worker dispatches GET requests atintrospection_pathto build_introspect_response() before the request reaches the ASGI application.

The response body is a JSON object with three sections:

  • runtime: Python version, GIL state, worker mode, server uptime.
  • worker: per-worker identity (worker_id) and live counters (active_connections).
  • config: theredacted_config_view() of the activeServerConfig— fail-closed via INFO_ALLOWLIST.
