Best Tessera Alternatives
An open, deterministic evidence layer for AI agents. Every answer is built from claims that trace back to exact source records; what can't be proven is refused, not guessed. Every agent action is drafted from verified claims, previewed exactly, and executed only behind human approval β with a receipt. Faithfulness is a measurable number in CI, not a vibe.
