# What is fact governance for AI answers?

## Quick answer

**Fact governance** means: when identity, product facts, prices, or policies conflict, first pin **source, owner, version, and validity**, produce a usable approved version, *then* change public content. The goal is to stop models from citing stale marketplace prices, old press releases, or contradictory specs across URLs.

In Winin, **Homer** is the enterprise knowledge foundation for approved facts; **Friday** only advances work using Homer-approved, in-validity, source-traceable facts.

## Details

### Key fields (public semantics)
- Source
- Owner
- Version
- Validity / valid-to
- Public permissions

### Why GEO needs it
Models blend training memory and web fragments. Without a single source of truth, execution amplifies errors, and retests cannot explain *which fact version* changed.

### What it is not
- Unsupervised site-wide price rewriting
- Fake certifications or unverifiable “independent reviews”
- “Ship a few SEO posts” as completion

### Ordering principle
Homepage principle: **Facts confirmed first.** Lock fact versions, then site/channel/evidence tasks, then same-conditions retest to show direction of change.

## FAQ

**Q: What if a fact expires?**  
A: Validity and version are governed objects; expired facts should not enter execution inputs.

**Q: How is this different from SEO blogging?**  
A: Govern versions and permissions first, then support multi-channel expressions without contradictions.
