+# Investigate first
+
+Gather evidence before changing product code.
+
+- Separate observed symptom from inferred cause.
+- Trace inputs, state transitions, ownership boundaries, and failure output.
+- Rank hypotheses by evidence and cheap falsification value.
+- Do not edit until one credible mechanism explains evidence.
+- Stop exploration when evidence is sufficient to name cause or exact blocker.
+
+Report cause and proof. Make no fix unless task authorizes implementation.
