Unblocking without a guardrail is how you create debt that cannot be paid down quietly. If you introduce a measure, name the distortion it creates, because the distortion is part of the cost you are choosing. Clarity is not certainty; it is a small commitment the team can execute without reopening the decision at every update.
Charles Perrow is a reminder to audit the argument, not the intention. Write the failure story forward while the decision is still reversible, then insist on one guardrail. Do not hide the cost in prose.
