January 2026 (2026-01) — OpenCSGs/csghub-server: Agent Memory Service API and Validation Enhancements delivered. Implemented a unified memory REST API with an adapter-based backend architecture to support pluggable memory backends. Added MemMachine adapter with mapping, search/list/delete semantics, and integrated it into Docker for local development. Enhanced memory error handling by moving handling into the handler, inlined pagination validation, and introduced validator tags for memory request bindings to enforce binding-level validation. Updated developer docs for the memory API and backend adapters. These changes establish a scalable memory backend framework, improve development and QA workflows, and reduce runtime errors across the memory service.
