avr_cold_boot_demo.py

=====================

Cold-boot live demonstration of the Adaptive Verified Runtime (AVR).



What you see:

  1. Sovereign kernel boots from scratch

  2. Lean invariants loaded and registered

  3. Kernel K0 deployed + WORM-sealed

  4. MLIR rewrite fires -> K1 candidate generated

  5. Lean verification runs against K1

  6. Speedup gate checked (1.05x minimum)

  7. Atomic FFI hot-swap: K0 -> K1

  8. Evolution metrics printed

  9. Rollback capability demonstrated

  10. Meta-learner weight update
