Verify the facts an agent's action depends on before it acts — ALLOW, REVIEW, or BLOCK.
Description
No action runs on a stale fact. · Kaval watches published sources you depend on, turns each material change into an evidence-anchored record in your schema, and keeps a signed history of what the source said when you acted. · The dangerous part isn’t when you’re wrong.It’s when you were right last month. · A check is only as goodas its view of the source. · Most edits are noise.The one that costs you looks exactly like the noise. · Register a source, bind a schema, subscribe once.
