pub fn codex_start_trigger(payload: &Value) -> Option<Trigger>Expand description
How a Codex session started, from its session_meta: a subagent’s (source.subagent) is its parent’s;
codex exec (codex_exec) and supercode’s runtimes (supercode, supercode_*) are programs. A TUI
start makes no claim (agents run the TUI in panes too), nor do other originators. source alone cannot
tell programs apart: its vscode covers every app-server client, supercode’s included.
