Test explanations against evidence from the setting.

Build a structured diagnostic record around one behavior.

Start with one behavior

Who needs to do what, where, and when?

Then test what in the setting could keep the pattern in place.

Conditions to examine

Do not choose the explanation before looking at evidence.

Start with one condition and inspect what could support or weaken it.

1 condition shown for Material.

The next decision

Evidence from the setting decides which condition is carrying the pattern.
