Lesson 126: Shot noise vs decoherence slicing
Focus
Separate statistical noise from calibration drift before claiming algorithm wins. Token Shot noise vs decoherence slicing:126 keeps neighbouring lessons differentiable.

821151. - 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.
