Not a rule
Engineering convention — not codified (Stripe, Xero Idempotency-Key, QBO requestid). US GAAP governs recognition, measurement and presentation — not the mechanics a bookkeeper uses to get there. Anyone citing a standard for this word is citing the wrong thing.
Every citation in this system, with the text we read and the date we checked it, is in US GAAP and where these rules come from.
