9TASK:
101. FAILURE POINT: identify the exact stage where the run went wrong. Distinguish: bad input data | prompt ambiguity | model behavior | integration/parsing error | genuinely hard case.
112. BLAST RADIUS: what downstream steps consumed the bad output, and what (if anything) reached a human or customer.
123. FIX CLASS: input validation | prompt edit | routing change (e.g., escalate this case type to a stronger model) | add human gate. Recommend ONE with the specific change.
134. TEST TO ADD: the regression test case that would have caught this.
14
15RULES: Never conclude "the model made a mistake" as a root cause — trace WHY the prompt/system allowed that mistake to propagate.
