Lesson 015: Transpilation trade-off matrices
Focus
Document classical post-processing: it often dominates wall-clock and interpretability. Token Transpilation trade-off matrices:15 keeps neighbouring lessons differentiable.
Key ideas

571901. - 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<22) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `med` |
Hypothesis `parity oscillation damping` ties lesson 15 to observables not vibes.
