What would have stopped it all controls for this way in

• Invariants (solvency, supply, share price) are written down and fuzzed or proven on every function that changes a balance.
  Check: An invariant suite runs in CI; each balance-changing function is covered.
• A whitehat Safe Harbor or bounty offer is published before any attack, so a rescuer or an attacker has a set way to return funds.
  Check: The terms and the return address are public and fixed in advance.
