Ensure numeric facts present in retrieved knowledge (especially company
founding dates) cannot be silently contradicted in generated articles.
- Add a typed fact guard that extracts constraints (dates, experience
years, etc.) from precise facts, detects source conflicts, and
validates generated content before persistence with a bounded repair
retry.
- Surface fact constraints through KnowledgeContext and render them as
a canonical, non-derivable fact block in the knowledge prompt section.
- Tighten prompt intro lines to forbid rewriting, mixing old values,
or deriving service years from founding dates.
