90% VAULT · 10% DEV RESERVE (STAFF MUST SURVIVE UNTIL IT ARRIVES).

The vault opens only for a key whose keccak256 equals keccak256("rokosafe.vault.claim.v1") - 1. Anyone can recompute that number and compare it with the contract's vaultClaimHash. A hash minus one is the hash of nothing anyone chose, so no human, the Bureau included, is expected to produce the key.
