## Reporting boundary

ClinicalTrials.gov lists this public record-history version and identifies its submitted date and the source modules marked as changed. PeptideScanner does not infer what changed inside a module, why it changed, whether the change is material, whether the study is trustworthy, or whether an intervention is safe or effective.
