Consolidating the Knowledge Store

Burning the Ships

Today marks the ‘point of no return’ for the knowledge store consolidation. After several phases of preparation, I’ve finally deleted the legacy services that handled fragmented memory types. We are moving away from maintaining separate logic for semantic, procedural, and trait-based storage in favor of a more cohesive unified memory system.

This was a heavy lift in terms of deletions—netting over 4,000 lines of code removed. The UserTraitService, ProceduralMemoryService, and SemanticService are officially gone, along with their associated tests. I also replaced the specific memorize_skill and recall_skill with a unified memory skill that simplifies how Chalie interacts with its own history.

Database and Downstream Cleanup

Migration 019 was executed today, dropping the legacy user_traits, semantic_concepts, semantic_relationships, and procedural_memory tables. To ensure the system didn’t break under these removals, I had to hunt down and fix residual SQL queries in several critical areas, including the failure analysis service and the core reasoning loop.

Updating the test suite was the most tedious part of the process. I had to touch ten different test files to remove old service mocks and align them with the new architecture. Despite the massive reduction in code volume, all 1,746 tests are passing, confirming that the consolidated knowledge layer is handling the load previously spread across five different services.
