Summary

OpenWiki 0.4.0 introduces a claims runtime designed to prevent long-term documentation memory from becoming unreliable as its underlying code evolves. When the system writes wiki content, it records each factual claim alongside versioned code evidence, allowing deterministic checks to flag claims as stale whenever their supporting source changes. Stale claims remain uncertain until a future update verifies them, either refreshing their evidence if still correct or revising both the claim and wiki content if no longer true. OpenWiki projects page-level provenance and verification information into Open Knowledge Format (OKF) v0.2 metadata while retaining detailed claim records in sidecar files. In evaluations replaying repository changes, the claims runtime increased supported claims from 92.9% to 97.8%, reduced stale claims from 3.5% to 0.5%, and eliminated hallucinated claims, enabling documentation to self-correct incrementally rather than requiring complete regeneration.
