● Append-Only Revision Ledger

Revision history — Amsterdam Open Air

Immutable revisions: Every approved edit creates a new sequential revision number; prior versions are never deleted in place.
Auditable rollbacks: Even a steward rollback is recorded as a new numbered revision pointing to the restored state.
Open Commons licence: All textual revisions are archived under CC BY-SA 4.0 .

Every revision to a folkroom page is public and append-only. Nothing is overwritten in place.
