+### Paginated Resource Lookups (`ledger/acctupdates.go`)
+The `lookupAssetResources`, `lookupApplicationResources`, and `lookupBoxResources` functions follow the same pattern: walk in-memory deltas backwards, query the DB, then merge the two result sets. These functions must stay closely aligned — a bug fix or structural change in one almost certainly requires the same change in the others. They are candidates for future consolidation into shared generic logic.
+
+Their corresponding `Ledger`-level wrappers in `ledger/ledger.go` (`LookupAssets`, `LookupApplications`, `LookupBoxes`) must each hold `trackerMu.RLock()`, matching every other method that accesses tracker state.

 - Interface-first design for testability and modularity
 - Dependency injection for component assembly
