ADR 0547 clause 9: the vault writes the hash of each bus account it holds into bus-accounts.<user>. The grants part watches that state (no timer), carries the hash with each shadow user in memory only, and its user-list tool says per user whether a hash is held and how its line would differ from the loaded one (same, adds, left out for want of a credential, loses its login); never the hash, since bcrypt salts make two hashes incomparable. Take-over names the users with no hash. Issue: 1945
