+
+This update covers verified engineering progress during the previous seven days. Work in private repositories is summarized without private links or implementation identities; links to public changes appear directly beside the summaries they support.
+
+## Rusk
+
+
+### Core (Private Repo)
+
+Updated proof-version selection and transaction-data pricing, alongside clearer build guidance.
+- Changed proof verification to use the versions supplied by the calling application.
+- Clarified build-cache guidance, linked archive changelog entries, and added a check for the archive benchmark.
+- Added activation-controlled pricing for transaction data, allowing its data size to contribute to the gas cost.
+### Piecrust (Private Repo)
+
+Updated contract-state handling and execution checks to improve consistency across saved states and contract runs.
+- Documented the order used to finalize contract execution.
+- Added tests covering contract initialization when execution runs out of gas.
+- Added a check that exercises process-signal forwarding.
+- Added activation controls for the contract-state format transition.
+- Extended saved contract-state commitments to include memory size.
+
+## Forge
+
+Restored reproducible smart-contract project builds and corrected event registration in the starter template.
+- Registered the counter template's event type and corrected the event-registration guide so generated projects could decode emitted events. ([PR #43](https://github.com/dusk-network/forge/pull/43))
+- Pinned Rust 1.95 and compatible dependencies, made dependency updates respect that compiler version, and restored CLI tests and code-quality checks. ([PR #48](https://github.com/dusk-network/forge/pull/48))
+
+## Bls12\_381
+
+Updated the hash-to-curve interface with stable compatibility guarantees and expanded checks for reduced-feature builds.
+- Stabilized the opt-in hash-to-curve interface while preserving its existing behavior and compatibility alias, and added checks against RFC 9380 reference vectors. ([PR #193](https://github.com/dusk-network/bls12_381/pull/193))
+- Repaired tests for reduced-feature configurations and included them in the existing test and code-quality checks. ([PR #190](https://github.com/dusk-network/bls12_381/pull/190))
+
+## Proof-wire blinding
+
+Updated proof masking and setup-parameter capacity across the native and WebAssembly proof tooling.
+- Added extra random masking to three proof wires to match their two verification openings, with corresponding tests. ([PR #976](https://github.com/dusk-network/plonk/pull/976), [PR #14](https://github.com/dusk-network/zk-tools/pull/14))
+- Increased the setup converter's parameter allocation by three powers to accommodate additional proof-masking values. ([Commit 384608ae](https://github.com/dusk-network/trusted-setup/commit/384608ae361325f60b8af92d8da4407e9615c797))
+
+## Dusk Website (Private Repo)
+
+Expanded the team page with more detailed leadership profiles.
+- Expanded leadership profiles on the team page to give visitors more information about the people behind Dusk.
+
+## W3sper (Private Repo)
+
+Improved transaction-signing reliability for selected wallet profiles.
+
+## DuskEVM (Private Repo)
+
+Improved node synchronization reliability.
