Previous value: -"WHAT ANGLE THIS POST IS BUILT ON — the single most valuable field here, and the only moment it can ever be recorded. post_performance groups on it to answer \"which hooks work\", and it needs 5 posts sharing ONE hook before it will call anything a winner, so REUSE THE SAME WORDING across a campaign instead of rephrasing it every time. Best of all, pass a hook id from list_hooks (e.g. \"direct_callout\", \"mid_problem\", \"before_after\") — those fold onto a stable key however they are spelled, so a whole brand accumulates evidence on one row. Your own wording is fine too; it just only groups when you repeat it exactly. Omitting it means this post can never vote on which hook works."New value: +"WHAT ANGLE this post is built on, recorded only at publish time. post_performance ranks hooks on it (a winner needs 5 posts sharing ONE hook), so pass a list_hooks id (e.g. \"direct_callout\", \"before_after\") or reuse your own wording EXACTLY across a campaign.
