"""Qwen 3 agent plan — structured test with playbook building.

Runs a series of staffing operations through the agent gateway,
uses qwen3 for generation, observes outcomes, and builds playbooks
that future runs can use to improve.

The plan:
1. Check existing playbooks (learn from prior runs)
2. Process 5 contracts with hybrid search
3. Ask 5 intelligence questions (compare to SQL ground truth)
4. Have qwen3 self-evaluate each answer
5. Log successes/failures as playbook entries
6. Summarize: what worked, what didn't, what to change next time
