Lesson 107: Hybrid classical loop tracing
Focus
Document classical post-processing: it often dominates wall-clock and interpretability. Token Hybrid classical loop tracing:107 keeps neighbouring lessons differentiable.
Key ideas

- 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 107 to observables not vibes.
