Somebody has to say that this batch may be spawned. That decision rests on four kinds of evidence: what you saw, what you measured, what the process record shows, and what a laboratory confirmed.
Any one of them alone will mislead you. Colour tells you about heat history but nothing about ammonia. A squeeze tells you roughly about water but nothing about pH. The batch curve tells you what the tunnel did but not what the compost became. Decide on the set, and write the name of whoever decided beside the batch number.
