- Fixed _vector_search() to check uses_named_vectors() before adding 'using' parameter
- Fixed _person_vector_search() to detect person collection vector size and use appropriate model
- Resolves 'Not existing vector name error: openai_1536' for single-vector collections
- Resolves embedding dimension mismatch between heritage_custodians (1536-dim) and heritage_persons (384-dim)
- Implemented a new script `test_pico_arabic_waqf.py` to test the GLM annotator's ability to extract person observations from Arabic historical documents.
- The script includes environment variable handling for API token, structured prompts for the GLM API, and validation of extraction results.
- Added comprehensive logging for API responses, extraction results, and validation errors.
- Included a sample Arabic waqf text for testing purposes, following the PiCo ontology pattern.
