"Most breakdowns are preceded by a long period of unnoticed warning signals.
Most disasters begin as a reasonable exception. In a metric proposal that will change incentives, the system learns the exception faster than it learns the risk.
In a metric proposal that will change incentives, the argument will be that you are “unblocking” the team. Unblocking without a guardrail is how you create debt that cannot be paid down quietly. A standard you cannot apply in one pass is not a standard; it is a preference disguised as governance. Name what you are refusing to optimize, so future changes do not quietly destroy the property you thought you were protecting.
Barry Turner is a reminder to audit the argument, not the intention. Draft the future critique now: how this fails and what justification you will be tempted to use, then name one guardrail. End with one move, not three.
