An independent research programme asks whether an automated system's account of its reasoning and actions can be checked by someone who was not present.

Landing page captured for the 2026-09-03 issue.

Field notes

The programme defines a Testimony Record for claims about what an automated system believed, what evidence it used, what contradicted it, and who approved an action. Its four conformance levels progress from append-only record structure to evidence-linked disagreement, externally assigned risk and named approvals, and replayable integrity checks. The site also identifies a 19,668-respondent audit in Working Paper No. 1 and describes a correction to an earlier published result.
