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.

161721. - 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.

| Artefact | Honesty check |
|----------|---------------|
| Exact statevector (n<21) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `low` |
Hypothesis `success amplification lift` ties lesson 124 to observables not vibes.
