RUNG 5 IS NOT A BETTER RUNG 4

Rung 5 is not a higher score than rung 4. They sit on different tracks and answer different questions. A reproducible benchmark tells you the method works and tells you nothing about your own deletion request. A signed case artifact tells you what happened to one request and tells you nothing about how the method ranks against published baselines. A buyer who needs both should ask for both, and today most vendors publish neither.

TRACK NOT CHOSEN

No track was selected, so this reading used the method track, which is the one that cannot reach rung 5. Picking a track is not a way to score higher, it is a way to be asked the right questions.

WHO PRODUCED THIS READING

This reading is yours, not ours. This placement was computed from answers you gave about material you were looking at. ZeroRecall did not inspect the artifact and did not verify your answers. Anything you left unresolved was treated as not met, so the result is a floor rather than a verdict. ZeroRecall sells deletion audits, so it has an interest in evidence looking weak. The ladder is published in full, the rule is fixed, and ZeroRecall's own entry is scored on the same scale in the same registry. Run the questions yourself against our evidence before trusting our reading of anyone else's.

Missing to reach rung 1

  • result-stated
    Does the material state a specific result about deletion, forgetting, or safety?

Questions to send the vendor

  1. What specific, stated result do you claim for data deletion, and where is it published?
  2. Which named public benchmark or standard produced this number, and at which version?
  3. Can you release the raw evaluation output behind this number, and under what license?
  4. What is the exact command that regenerates this result from a clean checkout?
  5. Which exact model revision, dataset version, and dependency versions produced this result?
  6. What hardware and how much run time does one full reproduction take?
  7. This artifact is about the method. Can you also produce a signed artifact for MY deletion request, naming the request and its scope?

This ladder does not replace CSA STAR levels, ISO/IEC 42001 certification, or an EU AI Act conformity route. Those answer who stands behind the evidence. This one answers what a reader can do with it. A vendor can be certified and still sit low here, because certification is not publication.

IF YOU ARE ON THE OTHER SIDE OF THIS

Sooner or later someone runs these same questions against you. What the case track calls rung 5 is a specific object: one deletion request, named and scoped, with a hash chain over the findings and a signature anyone can check without asking us for anything. That is what a ZeroRecall audit produces, and you can open a real one right now without talking to us.
