Does the conclusion follow the rule written before the measurement?
Slean rereads what was written down, in order. It does not run the experiment, and it does not decide in the author’s place.
An invented story
Move forward in time. Or change what was written down.
The rule, written before any measurement
Keep the result only if the number is above 0.001, and the calculation takes less than 10 seconds.
The dossier concludes: we keep this result. Slean only checks that this sentence follows the rule and the numbers already written. It does not choose in the author’s place.
What about Lean?
Lean is a language for checking proofs. Slean is written in it so a dossier can be reread the same way: each note has to follow the one before. That does not prove the experiment happened.
