Plan a review sample for this frozen TestBucks evaluation batch. Separately estimate unsupported bug reports and incorrect pass verdicts. Define each population and sampling unit, propose sample sizes for an explicit precision target, and stratify important journeys and user groups. Show the plan before selecting cases. After approval, select reproducibly at random, preserve original evidence, and prepare a compact review packet. Do not invent review labels. Once independently checked labels are available, calculate rates and appropriate confidence intervals, preserving unresolved cases and critical findings separately. State what these estimates do not establish about missed bugs or release safety.
