Lesson 100: Cross-vendor fidelity comparisons
Focus
Prefer falsifiable hypotheses (shot count, fidelity floor) over buzzword proofs-of-concepts. Token Cross-vendor fidelity comparisons:100 keeps neighbouring lessons differentiable.

22138. - 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<21) | qubit ceiling note |
| Noisy emulation | pauli/channel parity |
| Device trace | leakage / crosstalk tag `low` |
Hypothesis `parity oscillation damping` ties lesson 100 to observables not vibes.
