Step 2

The DBA reviews

Checks the SQL without ever seeing the values.
Step 3

The business approves

Confirms the change, with the values masked.
Step 4

sealfix runs it

Exactly as approved. If anything differs, nothing changes.

Not in screens, logs or error messages. Only the fix itself reads the values.

With the same approvals as the fix.
