Quantum AI Intermediate — 073: budget shots against calibration drift on `Post-processing inversion checks` — memo `868745 [73]`

Lesson 073: Post-processing inversion checks

Focus

Treat placeholders as mandatory—rename qubit lines and budget shots immediately. Token Post-processing inversion checks:73 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Post-processing inversion checks · drill v3 · spin 127966.
• 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.

- [ ] SWAP count vs manual estimate delta noted
- [ ] layout seed `S-1233`
