- Add comprehensive logging to verify IDs sent to LLM (sent vs received)
- Enhance prompt with explicit ID bounds (0 through N-1)
- Add validation warnings for missing and extra IDs from LLM responses
- Improve error message clarity for invalid dedupe IDs
- Log actual IDs sent to LLM to confirm no index leakage
This helps diagnose cases where the LLM returns IDs outside the valid
range (e.g., ID 19 when only 0-18 were sent).
