+## Notes
+
+- seqno=0 payment also deployed the wallet contract (state_init included automatically). Wallet went `uninitialized` → `active`.
+- `runGetMethod` (seqno query) requires POST — fixed in scratch script.
+- `TonStakingType` was only exported as a type, not as a value — fixed in `js/index.ts`.
