Codex App Server Methods: Core Lifecycle

Purpose

This is the one-level core-method reference.

It summarizes the core lifecycle method families and points to deep method docs.

Method Families

Handshake

• initialize
• initialized (notification)

Required before any non-handshake call.

Thread lifecycle

• thread/start, thread/resume, thread/fork
• thread/list, thread/loaded/list, thread/read
• thread/archive, thread/unarchive, thread/name/set
• thread/compact/start, thread/rollback
• thread/backgroundTerminals/clean (experimental)

Turn lifecycle

• turn/start
• turn/steer
• turn/interrupt

Review lifecycle

• review/start

Supports inline and detached delivery modes with lifecycle markers in stream items.

Core Behavior Rules

• one active turn per thread at a time
• turn completion/terminal state is signaled by lifecycle notifications
• item completion is authoritative for final item state
• interruption settles only when terminal turn lifecycle is emitted
