Jun 1, 2025June 2025: Key outcomes include a reliability-focused refactor of the testing framework to use full_op_id consistently across operator_to_stats, cost_model, optimizer, and scan tests; reorganization of Abacus research tooling into an abacus-research directory with updated demos/configs and new arguments for model selection and processing strategies; and alignment of the query optimizer with embedding models by excluding them from certain convert operations and bumping the project version to reflect changes. These changes strengthen test reliability, shorten experimentation cycles, and reduce risk of incorrect rule application in production-like scenarios.
