32. ## Method
33. ​
34. `protocol-bonds-total-staked` is only ever *increased* by `register-for-bond`. I listed the pox-5 contract's print events
35. (`GET /extended/v1/contract/SP000000000000000000002Q6VF78.pox-5/events`, paged, throttled) and kept prints containing
36. `(bond-index u2)` and `(topic "register-for-bond")`. Each such print carries `staker` and `sats-total`. The results are exactly
37. 3 prints, and they sum to the current map value to the sat (50,510,000,000), so no registration is missing and no partial
38. unstake has reduced the total. Every attributed amount matches the `sats-total` field in the tx's own pox-5 print event.
