Lesson 013: Two-qubit basis and CNOT scaffolding
Focus
Separate statistical noise from calibration drift before claiming algorithm wins. Token Two-qubit basis and CNOT scaffolding:13 keeps neighbouring lessons differentiable.

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

1. Target CI width `0.07` @ confidence `96`
2. Pilot shots `768` expanding to `5556` if variance plateaus
3. Telemetry fields `job_id,device_tz,mitigation_bundle`
4. Stop rule `halt if RB infidelity > 0.002094`
