Preflight before trust

Check what is known.
See what is missing.

Zambo Check is an evidence-aware preflight for claims, tools, actions, authorization, completion, outputs, freshness, conflicts, and prompt security. It reports observed evidence without pretending that a model opinion is proof.

Check

Establish the claim, boundary, and question before treating an answer as evidence.

Execute

Use the live Zambo capability layer to gather the relevant observation or response.

Verify

Inspect the returned status, evidence, freshness, risk, and verifiable receipt.

Proof

Preserve the response integrity hash and keep the scope of the result explicit.
