Refract is open-source core observability for MediaWiki and public revision histories. Refract observes change across time. Healthcare-specific logic lives in private repos.
- Fetching and replaying MediaWiki revision histories.
- Deterministic extraction of what changed between revisions.
- Provenance records for claims, sources, page structure, links, categories, templates, talk-page references, and page moves.
- Claim-state timelines: structured records of how claims evolved across revisions.
- Optional model-assisted interpretation that receives only extracted evidence and emits bounded labels with confidence.
- Generic benchmarks that check whether Refract detected publicly observable revision-history events.
- Connectors for public or user-controlled MediaWiki instances.
- Healthcare-specific logic: claim supportability thresholds, jurisdiction routing, authority-weighting, clinical source ranking, bitemporal gap detection, claim-context mapping, and review workflow triggers.
- Claims that Refract determines truth, predicts external events, or ranks people.
A valid Refract contribution should be useful for observing public-knowledge change on Wikipedia, Fandom, or another MediaWiki instance — across time, not just at the current revision — without relying on healthcare context or private decision criteria.
