Feb 1, 2026February 2026 — Delivered Time-Sorted Unique Identifiers (TSID) integration in the eugenp/tutorials repo, enabling time-ordered, globally unique IDs for core entities. Implemented a new dependency for Hypersistence TSID, added unit tests to verify TSID generation, uniqueness, and serialization, and fixed a broken JTE template test to restore CI reliability. This work enhances data traceability, ID scalability, and test confidence across services, contributing to more robust retryable identifiers and safer data migrations.
