Lesson 079: Post-processing inversion checks
Focus
Separate statistical noise from calibration drift before claiming algorithm wins. Token Post-processing inversion checks:79 keeps neighbouring lessons differentiable.
Key ideas

207749. - 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.
