Improved Domain and Source Verification Flow

We refined the verification pipeline to separate identity verification from factual verification. Domain ownership and corporate email confirmation establish profile ownership. Individual facts are then verified through linked primary sources or documented records. This layered approach scales better than single-step verification and allows partial verification without blocking profile creation. From an architectural perspective, verification becomes composable. Different facts can carry different verification levels, all visible to consuming systems. This makes AuthorityPrompt suitable for both early-stage companies and regulated enterprises without compromising trust signals.
