Lesson 101: Hybrid classical loop tracing
Focus
Separate statistical noise from calibration drift before claiming algorithm wins. Token Hybrid classical loop tracing:101 keeps neighbouring lessons differentiable.

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

| Artefact | Honesty check |
|----------|---------------|
| Exact statevector (n<18) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `med` |
Hypothesis `success amplification lift` ties lesson 101 to observables not vibes.
