/**
 * @file antigravity-transcript.test.js
 * @description An Antigravity (agy) session's conversation view: its
 * `transcript_full.jsonl` step log mapped to the Claude transcript shape —
 * the prompt out of `<USER_REQUEST>`, the model's thinking, text, tool calls
 * and tokens, each tool result tied to its call by step and an invalid call
 * marked an error — one "main" transcript, no subagent files, and a session
 * id that is no UUID finding nothing. The agy dir and the DB are temp dirs;
 * the steps are synthetic, in the shape agy 1.4 writes.
