Report for 2026-02-06

Key Accomplishments

cardano-ledger Integration:
- Major refactoring of cardano-ledger integration to introduce CanonicalType and proxy data structures.
- Successfully implemented and merged several SCLS namespaces.
- Consistently addressed feedback from the ledger team.
CIP and Specifications:
- Continuously updated the CIP with new findings and addressed community comments.
- Improved the CDDL specifications and added explicit key sizes to CHUNK records.
Testing and Validation:
- Enhanced testing infrastructure, including adding a structural validation test as well as a test suite for verifying the conformance of the CIP’s CDDL specification with the Haskell implementation.
Tooling and Performance:
- Completed the resourcet rework for better resource management.
- Improved scls-util with a diff command to compare SCLS files and visualize differences.
- Initiated the cardano-scrawls project, a Rust-based implementation of SCLS.
- Studied current cardano-ledger test suite in order to integrate SCLS export of ledger state and transactions for black-box testing purposes.

Continue the implementation of remaining SCLS namespaces in cardano-ledger.
Finalize the integration of SCLS in cardano-ledger.
Continue the development of cardano-scrawls.
Address any remaining feedback on the CIP and PRs.
Explore and implement further improvements for scls-util diff command.
Further explore the integration of SCLS export/extraction from cardano-ledger test suite for black-box testing.
