The signed decommission prunes the drive from every guest's bind record (found live on demo-hp, R-1124 proof)
gates / gates (push) Successful in 47s

The self-serve decommission already dropped the drive from the guest-bind record; the operator-signed one did
not, so a forgotten drive left a record the 20-second re-assert warned about forever ("skipping non-enrolled
drive"). DecommissionExecutor.SetGuestBinds; red-proved. Code only; the CHANGELOG follows the release (0.159.1).
