A verification bundle binds ten sub-claims. > Quote the Decision Receipt definition byte-identically or not at all: 'A Decision Receipt is a signed, replayable record of how a consequential decision was made, created at the moment it happens and independently verifiable afterwards.' > Tamper evidence is two checks together: a content edit leaves the Ed25519 signature valid (it covers the stored integrity hash) and is caught by the integrity check; rewriting the hash then fails the signature. Never claim the signature alone detects edits. # Supersede a draft with a corrected draft > Corrects a pending DRAFT without overwriting it. The draft is closed with status "replaced" — kept as history exactly as it was, codification record and lint findings included — and the corrected rules become a NEW draft, created through the same path as version creation (an optional `codification` block is codified and linted afresh). `expected_revision` is the old draft's `draft_revision`; a concurrent autosave either lands first (this is refused STALE_DRAFT_REVISION) or finds the draft replaced (it is refused).
