// Package husdcursor persists the HUSD indexer's scan position: the last block

// fully projected into the ledger, per chain. It lets a restart resume rather
|
|
// than rescan from genesis. The record is a singleton per chain id (deterministic
|
|
// storage id), lives in the global "system" namespace, and carries no money — it
|
|
// is pure indexer bookkeeping.
