April 2026 monthly wrap-up for moltbot/moltbot focused on reliability and user-facing observability around vector indexing. Implemented a warning mechanism for the memory index when the sqlite-vec extension is unavailable, preventing misleading success messages and surfacing potential vector recall degradation to users. The change ensures that if vector.enabled is true and vector.available is false, the system emits an error-level warning instead of reporting 'Memory index updated', clarifying that chunks_vec was not updated due to sqlite-vec being unavailable. When the vector path is healthy, existing success messaging remains unchanged. Per-file level warnings are emitted in writeChunks when chunks are written without vector embeddings. This work aligns with HELM-0251 (local dist patch) and HELM-0252, improving reliability and transparency for customers relying on vector recall.
