  "description": "Read a draft post against X's open-sourced ranking code. Returns what is already settled before you post: whether it enters the pool strangers are drawn from, how long it stays retrievable, which filters delete it, and which gates nobody can know in advance. Every claim cites a file and line in X's published source. Never writes the post. Nothing stored.",
