The strongest public story is not that we have a large corpus. It is that we are building a disciplined knowledge-engineering system: evidence has provenance, uncertainty is named, synthetic material is controlled, and mistakes can be corrected.
Corpus lifecycle
Scope → acquisition → rights → validation → release → correction → retirement.
Evidence engineering
Provenance, conflict, freshness and uncertainty — not silent selection of a preferred claim.
Synthetic data controls
Grounded generation, adversarial testing, human review. Model consensus is not truth.
Transparency
Corpus Cards, Dataset Cards, quality gates and an explicit list of open decisions.
