Every row is a `register-for-bond` call with `bond-index u2`. All three Stacks txs are `success`.

Row detail:

## Method

`protocol-bonds-total-staked` is only ever *increased* by `register-for-bond`. I listed the pox-5 contract's print events
(`GET /extended/v1/contract/SP000000000000000000002Q6VF78.pox-5/events`, paged, throttled) and kept prints containing
`(bond-index u2)` and `(topic "register-for-bond")`. Each such print carries `staker` and `sats-total`. The results are exactly
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
unstake has reduced the total. Every attributed amount matches the `sats-total` field in the tx's own pox-5 print event.
