Lesson 124: Shot noise vs decoherence slicing
Focus
Prefer falsifiable hypotheses (shot count, fidelity floor) over buzzword proofs-of-concepts. Token Shot noise vs decoherence slicing:124 keeps neighbouring lessons differentiable.

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