Overview: In April 2026, delivered a major registry enhancement for subdomain lifecycle management in MystenLabs/suins-contracts. Implemented parent-authorized pruning of expired subdomain records, enabling domain holders to reclaim expired child domains without the SubDomainRegistration object. Added end-to-end support with Registry::prune_expired_subdomain_record, controller::prune_expired_subname_by_parent, and comprehensive validation and tests. Introduced batch pruning for multi-subdomain cleanup, improved code reuse with a shared removal helper, and refactored for clarity and Move-pattern consistency. Restricted pruning exposure to package visibility to enforce authorization and updated events and imports to Domain types. Result: reduced stale data, stronger ownership guarantees, and maintainable code with 32 controller tests and 22 registry tests all passing. Technologies: Rust, Move, domain types; testing, refactors; business value: streamline reclaim process, improve data integrity, and reduce operational overhead.

January 2026 monthly summary for ens-app-v3 focusing on delivering SUI address support and block explorer integration, expanding test coverage, and aligning with the SUI ecosystem. This work improves user onboarding for SUI addresses, strengthens reliability through comprehensive testing, and ensures future compatibility with evolving address-encoder versions.
