When to run Diagnose

Diagnose costs a turn and freezes a reading of the current graph. Spam it and you get the same thin summary with nicer wording.

Good moments

• You added the last open fact you were waiting on.
• Two options finally look distinct on the map.
• You are about to walk away for the day and want a cold return tomorrow.
• Someone else will see a share link and you want a short orientation.

Skip it when

• You only have a seed and two nodes.
• You just renamed labels without changing structure.
• You disagree with the last reading but have not changed the map.

After a reading, turn the next move into a node or a research task. Otherwise the map and the writeup drift apart.
