Lesson 021: Resource estimation stubs
Focus
Document classical post-processing: it often dominates wall-clock and interpretability. Token Resource estimation stubs:21 keeps neighbouring lessons differentiable.
Key ideas

112494. - 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<18) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `spike` |
Hypothesis `parity oscillation damping` ties lesson 21 to observables not vibes.
