# Fact Check · hagaiw

> Maintain a session-scoped, source-backed FACTS.md containing only verified facts during long debugging, research, implementation, and review tasks. Use when a task needs a compact record of current claims, evidence, context, and freshness across turns. Initialize the book, read it before acting, add verified facts, reconcile stale or superseded records, and report the evidence. Do not use for one-off fact lookup, theories, opinions, decisions, or checking a finished document against its source.
