Lesson 091: Small-circuit fidelity heuristics
Focus
Document classical post-processing: it often dominates wall-clock and interpretability. Token Small-circuit fidelity heuristics:91 keeps neighbouring lessons differentiable.
Key ideas

843781. - Habit: pair each job with shot budget, mitigation profile, and a calibration fingerprint you could paste.
- Guardrail: write one line about where classical cost dominated the timeline.
