C14 · A different history, an open cause
Complete source: Original fiction. Two broad paper tabs have the same outline. TabOne has an earlier fold; TabTwo was uncreased. The same adult describes each short action as a similar gentle press on the same flat mat. TabOne rests bent and TabTwo rests flatter. Exact force/contact duration are not measured and there is one try per tab. Their prior histories differ; no next attempt is supplied.
Own invitation: What differs in the records and what prevents a universal history-only explanation?
Worked possibility and a different next teaching invitation
Source-supported possibility: The resting shapes and prior fold histories differ. Intended similar actions and outline/mat matches are useful, but exact contact/strength were not measured and there is only one try each. A question about prior history can guide more careful matching; it does not prove history alone caused every outcome.
Unknown/limits: Keep every missing force, path, future attempt, actual child operation and player response within this source’s stated limits. A complete fictional record is source evidence, not performed-investigation evidence.
Full next teaching: Use C15’s deliberately changed material question. Ask what was intended to change, which matches help and which unmeasured detail remains. Listen for a bounded relation instead of “different means unfair” or a universal material rule.
