Lesson 109: Hybrid classical loop tracing

Focus

Prefer falsifiable hypotheses (shot count, fidelity floor) over buzzword proofs-of-concepts. Token Hybrid classical loop tracing:109 keeps neighbouring lessons differentiable.

Key ideas

• Thread: Hybrid classical loop tracing · drill v9 · spin 264640.
• 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.
