Original fictional costume-stall prop guide. Job: record pitch and loudness descriptions without guessing missing words. Uncovered empty lid/tap report by helper: “lower pitch, soft”. Cloth-covered same lid/tap report: “not sure about pitch, soft”. Same observer spot is stated; force and cover fit are not measured. Before trying, helper predicted covered would seem softer. No sound-level reading or real child trial is supplied.

• Separate supplied pitch and loudness words for each row, retaining uncertainty.
• Compare the supplied loudness reports with the prediction, keeping measurement limits.
• Make matching uncovered/covered rows with action and exact report.
• Ask a useful further question for the stated accurate-guide job, with next result open.
