+## DuskEVM
+
+### Contracts (Private Repo)
+
+Strengthened DuskEVM contract reliability.
+
+### Adapter (Private Repo)
+
+Simplified native contract queries while preserving response handling and cross-network lookup behavior.
+
+- Replaced repeated native query and response-decoding code with a shared typed helper, retaining existing request ordering and error behavior.
+
+## Rusk
+
+### Wallet (Private Repo)
+
+Aligned wallet-cache indexes with note queries to reduce sorting during balance synchronization and spent-history reads.
+
+- Reordered note-cache indexes to match unspent-note and spent-history queries, avoiding additional result sorting.
+
+### Core (Private Repo)
+
+Reduced archive storage overhead and expanded block-processing controls, with faster access to account history and network statistics.
+
+- Separated node rollback handling and shared test setup, preserving the supported rollback behavior.
+- Added stored account and transfer counters that updated alongside finalized blocks, so statistics reads avoided recounting archive history.
+- Compacted Moonlight event storage, stored block hashes as binary values, removed unused indexes and retired legacy event tables while preserving history responses.
+- Linked archive records to their corresponding blocks and transfer groups, preserving consistent removal of related history entries.
+- Added a protocol-wide block gas ceiling with height-based activation and consistent remaining-gas checks across block processing.
+
+### Piecrust (Private Repo)
+
+Pinned test-contract builds and reorganized contract validation to make development checks more reproducible and easier to maintain.
+
+- Locked independently built test contracts to pinned dependency versions so clean builds reproduced their code and gas behavior.
+- Reorganized checks for contract functions, tables, memory, names and globals into dedicated validation modules.
