check_factread-onlyCost preflight before repeated paid or slow source-backed validation, especially across an agent fleet. Use before paid web search, metered scraping, browser/extraction, rate-limited APIs or multi-step validation when the caller already has a known value. Returns SAME_OBSERVED, CHANGED_OBSERVED, CONTESTED, STALE or UNKNOWN. Only SAME_OBSERVED can be considered for caller-policy-gated reuse; every
observe_factAfter independently performing a source-backed validation, deposit the observed result for later CHECKs. Returns accepted=true when a new observation is stored or deduplicated=true for a recognized retry/recent duplicate. Never OBSERVE hearsay. Optional Ed25519 proof establishes key possession and continuity, not truth or real-world independence.
