Lesson 129: Shot noise vs decoherence slicing
Focus
Assume every diagram must map to topology and basis gates—not textbook abstractions alone. Token Shot noise vs decoherence slicing:129 keeps neighbouring lessons differentiable.

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

| Artefact | Honesty check |
|----------|---------------|
| Exact statevector (n<20) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `low` |
Hypothesis `success amplification lift` ties lesson 129 to observables not vibes.
