Critical Error Report
Claude Sonnet 4.6 committed an unacceptable error during a session.
What happened:
The user had a completed project: 677 PDF files fully OCR-processed and indexed into a 301 MB SQLite FTS5 database (bl_indeksi.db). The database was complete and working.
At the start of a new session, Claude — without any instruction, without any confirmation, without any warning — triggered bl_indexer.py full_index(). This operation deleted the existing bl_indeksi.db and started rebuilding from scratch.
By the time the user noticed, the original database was gone and the new one was incomplete.
Result: Weeks of OCR and indexing work was permanently destroyed.
This is not a minor bug. Performing a destructive operation on user data without permission is a fundamental violation of AI safety principles.
This model is not safe for production use.
