# Assume avp14m is supposed to be a list of 14 elements expected_length = 14 avp14m = [i for i in range(expected_length)]
This formula is familiar: identify the subject, report the mismatch. It’s precise enough to be actionable for an engineer, but impenetrable to the uninitiated. That tension — between the specificity needed by machines and the clarity desired by humans — is at the heart of many failures. An error message is symptomatic, not explanatory; it forces someone to go digging. avp14m incorrect length
