Boundary

Refract does not decide what is true. Refract makes visible how public knowledge changes.

What Refract is

• A deterministic observation engine
• An audit trail for revision histories
• A framework for extracting structured evidence from unstructured diffs
• A platform for evaluating model-assisted interpretations against ground truth

What Refract is not

• A fact-checker or truth-verification system
• A moderation or content policing tool
• A predictive model for future edits
• A judgment engine for healthcare, finance, or legal decisions
• A replacement for domain expertise

Open source

What changed? — Everything Refract produces is auditable, reproducible, and inspectable.

Not included — Domain-specific decision judgment. Refract observes change. It does not tell you what to do about it.

The line

Refract stops at the boundary between observability and judgment. If a tool needs to decide whether a change is good, bad, true, or false, that tool lives outside Refract. Refract answers only: "What changed?"
