April 2025: Implemented robust handling for ChromaDB dimension mismatches when switching embedding models in mindverse/Second-Me. The feature automatically detects the target model’s embedding dimension, verifies existing ChromaDB collections, and reinitializes them when a mismatch is detected to preserve data integrity. Includes enhanced logging and updated user documentation to support model migrations with minimal downtime and clear traceability. Result: increased reliability during embeddings model changes, reduced manual reindexing, and clearer guidance for developers and operators.
