Worked on stabilizing and validating the LIT-Protocol/js-sdk test suite, focusing on backend development and testing using TypeScript and JavaScript. Addressed reliability issues by refactoring logger tests to improve import structure and assertion logic, ensuring accurate validation of logger configurations and log retrieval. Updated unit tests for wrapped-keys access control conditions to reflect the correct return structure, and enhanced BLS session signature verification tests by incorporating the issuedAt timestamp for proper signature validation. These targeted improvements reduced CI flakiness, increased test determinism, and provided a more reliable foundation for downstream development and releases within the LIT-Protocol/js-sdk repository.
