Layer 1 — Profile

Grounding Check (free tier) — POST a statement about the entity and get coded verdicts (supported | contradicted | unverifiable) with confidence and citations against the signed verified record. The guardrail hook: run generated text through it before asserting an entity claim. Zero LLM — deterministic assertion extraction + the canonical-field equivalence ladder, so granularity differences ("Austin" vs "Austin, Texas") are supported and out-of-record assertions return unverifiable, never guessed. Free tier, rate-limited.
