Fisher Information Geometry and the Thermodynamic Cost of Self-Referential Calibration

Version 2 adds a new Section 8: Numerical Demonstration, a self-contained 20-dimensional linear-prediction simulation confirming the three core predictions (delusion-correction separation, detectable staleness, optimal calibration budget) under continuous drift.                                                                                                                                                                         

Changes from v1:

  - New Section 8 with three figures and reproducible Python code                  

  - Abstract: corrected ln 2 factoring to match Theorem 5

  - Detectability proof: fixed θ₀ linearisation

  - Additivity proof: added separable-DOF qualifier

  - Discussion: updated summary table to reference numerical results

  - Editorial: minor wording improvements throughout
