Lesson 137: Cost models for QPUs
Focus
Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Cost models for QPUs:137 keeps neighbouring lessons differentiable.

- Guardrail: write one line about where classical cost dominated the timeline.

1. Target CI width `0.09` @ confidence `96`
2. Pilot shots `512` expanding to `6645` if variance plateaus
3. Telemetry fields `job_id,device_tz,mitigation_bundle`
4. Stop rule `halt if RB infidelity > 0.002681`
