Lesson 099: Small-circuit fidelity heuristics
Focus
Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Small-circuit fidelity heuristics:99 keeps neighbouring lessons differentiable.

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

Shot budget tableau
1. Target CI width `0.1` @ confidence `96`
2. Pilot shots `1024` expanding to `10319` if variance plateaus
3. Telemetry fields `job_id,device_tz,mitigation_bundle`
4. Stop rule `halt if RB infidelity > 0.002537`
