Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.
MIT-0

Contract
- anyio.run executes an async entrypoint coroutine and returns its result
- create_task_group coordinates concurrent tasks and manages their lifecycle
- create_memory_object_stream provides typed asynchronous item streaming between tasks
- move_on_after cancels execution when the allotted timeout duration expires
- Event facilitates asynchronous signaling and task coordination
- to_thread.run_sync offloads blocking synchronous execution to worker threads
