## Fields
- `slug`: LeetCode problem slug
- `solution_id`: unique id, problem + approach index + language
- `primary_algorithm`: normalized algorithm/technique label
- `verified`: true/false for Python (execution-checked), null for other languages
- `messages`: chat-format (system/user/assistant), ready for SFT
