/**
 * @file Tests POST /api/hooks/event for hooks marked `tool: "codex"` (sent by
 * Codex through server/lib/codex-hooks.js): the session is created as a Codex
 * one with no transcript path, a PermissionRequest becomes the permission
 * Notification (awaiting flag + the codex lane's needs_action, never the claude
 * lane sharing the directory), no stage detection on a codex lane, and a
 * sub-agent thread's lifecycle hooks dropped while its tool calls land on the
 * root session, a main agent made for a session the journal poll imported first,
 * and the install/remove routes refusing another site. CODEX_HOME and the DB
 * live in a temp dir.
