Nov 1, 2024November 2024 — liam (liam-hq/liam). Delivered the Schemarb-prism Parser with new Prism-format support and a modular parser architecture; strengthened schema parsing with type-safety, safer extraction, and cleaner exports; and fixed default id column behavior to be unique and primary by default in schema factories. Integrations include adding tests and integrating the new parser into the main parser index; added documentation for bigserial primary keys to improve PostgreSQL compatibility. These changes enable a new schema-definition language, reduce maintenance risk, and improve reliability for schema-related deployments, delivering measurable business value across data modeling and runtime correctness.
