Model X-Ray correction
Status reviewed 4 September 2026 · validation pending
What changed
We have withdrawn our earlier structural-location, knowledge-separation, portrait-visualization, lesion-response and legacy simulated-quantization findings. An adversarial re-audit found defects or missing validation controls that prevent those results from supporting the interpretations previously attached to them.
Existing example reports, articles and related figures are historical records, not current evidence. They must not be used to make research, product, safety or deployment decisions.
Why the earlier evidence is insufficient
The re-audit identified the following method-neutral defect classes. Not every class applies to every historical item, but together they prevent the former interpretations from being treated as current evidence.
- Release identity and version control: public artifacts and interpretations were not consistently bound to one verified release state.
- Construct and criterion validity: some observations were used to support broader location, knowledge or robustness interpretations without an adequate independent criterion.
- Controls, repeatability and transfer: the available controls and replications were not sufficient for the scope of the public conclusions.
- Execution fidelity: legacy simulated-quantization observations cannot establish behavior under a real deployment execution path.
- Reporting sensitivity: presentation-format effects, uncertainty, abstentions and failure boundaries were not excluded or stated consistently enough.
Current evidence status
| Earlier claim family | Current status |
|---|---|
| Structural location and derived severity | Withdrawn. No replacement result is published. |
| Knowledge separation and internal readout | Withdrawn. No replacement result is published. |
| Portrait visualizations as validated evidence | Withdrawn. No replacement protocol has passed validation. |
| Lesion-response interpretation | Withdrawn. No architecture or robustness conclusion is current evidence. |
| Legacy simulated-quantization interpretations | Withdrawn. A simulation cannot establish behavior, quality, safety, performance or deployment readiness. |
| New Model X-Ray result set | Validation pending. No new public result is approved. |

What happens next
Replacement figures will be published only after a frozen, preregistered validation program completes held-out controls, repeatability and transfer checks, an adequately powered follow-up, independent review and external validation. Any future public release will state its intended use, uncertainty, abstentions, limitations and out-of-domain scope.
Model X-Ray remains research-stage. It is not a diagnostic, a quality or safety grade, a certification, or a substitute for task-specific evaluation.
Service-status boundary
This correction records the evidence status only. It does not announce an operational service pause. Any statement about scan availability or paid activation will be dated and published only after the relevant service controls have been deployed and verified.
No scan order, paid-plan activation or payment action is offered on this page.
Revision note: this notice supersedes earlier Model X-Ray evidence claims; it does not erase the historical record. If a linked legacy item remains accessible, this correction controls its current interpretation.
