Lesson 127: Shot noise vs decoherence slicing
Focus
Treat placeholders as mandatory—rename qubit lines and budget shots immediately. Token Shot noise vs decoherence slicing:127 keeps neighbouring lessons differentiable.

322066. - 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.
