Description

Users have no visibility into how their queries are being executed or optimized by the AI engine.

Requirements

• Implement an EXPLAIN <query> command.
• Output should show:
  • The parsed SQL structure.
  • Whether the result was served from cache (and the cache similarity score).
  • The execution path chosen by the RL agent (with Q-values if possible).

Impact

• Critical for debugging and understanding AI optimization decisions.
