new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

1 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Diagnosis showed content gaps, not retrieval failures, justified adding URL and PDF sources

The scripts/diagnose-exam.ts tool revealed that of 21 failed exam checks, zero were retrieval failures and all 21 were content gaps. A reranker would have changed nothing — the brain needed more material. This data-driven finding justified the decision to add URL and PDF ingestion rather than optimizing retrieval.
