Keep the lesson for the next incident
Save the coverage story
Record intended segments, screening criteria, actual participant context, dropouts, and the decision affected. Include a case where a participant looked suitable but did not perform the task. Keep the evidence link instead of summarizing fit as a percentage.
Improve recruitment planning
Add context checks, access prompts, and a coverage review to the research brief. Show how the change would have caught this mismatch earlier. Allow a study to declare a narrow scope rather than forcing every round to claim broad coverage.
Watch the next sample
Set a signal such as identical recruitment sources, unusually high product familiarity, or missing access adaptations. Assign an owner to review the sample before sessions begin. Reopen the plan when the signal appears or a new segment changes the decision.
What to carry forward
The learning record should connect the recruitment mismatch to the changed planning practice and recurrence signal. State which findings were narrowed or retained. Treat coverage as a living decision boundary that can improve with each research round.

Keep the decision with the work.
Use a Work Item in Aglet to record the problem, the evidence you have, and the next decision. Add an owner and priority, then keep updates in the discussion so the next person can follow the reasoning.
