Code

After `Promise::and(...).then(callback)`, the callback cannot tell which joined promise failed; a failed transfer leg leaves funds stranded

`store::` collections write lazily: document `flush()` before `env::storage_usage()`, or provide a `measure_storage` helper (and a storage estimator for caller-funded deposits)
