  Migration: state the algorithm and lock mode, and why it runs before the release
  
  hadb1 is MySQL 5.7, so adding a column rebuilds the table rather than only touching metadata.
  At ~53k rows that is seconds and InnoDB permits concurrent reads and writes throughout, but
  ALGORITHM/LOCK are now stated explicitly so it fails loudly rather than quietly taking a table
  lock if that ever stops holding.
