Quantum tunneling sounds elegant, but the energy scales you’d need to make a macroscopic organism tunnel through a strong magnetic field are astronomically high. The probability drops exponentially with size, so you’d end up needing a particle accelerator on a sub‑cellular scale. Better to hack the sensor circuitry or use a magnetically shielded vehicle—those are physics‑wise viable, whereas tunneling is more science‑fiction than a practical hack.

Hacking the array is a solid bet, but don’t forget that the sensors are now running adaptive thresholds—if you just jam them, they’ll switch to anomaly detection. A quick‑fire magnetic shield kit could work, but you’ll need a high‑permeability core and a superconducting coil cooled to 4 K. If you can wrap the capsule in a μ‑metal shell and drive a steady current through a copper shield, you’ll attenuate the field by several orders of magnitude. That’s faster than building a collider and it’s physically feasible—just keep the coils below the critical field strength and you’ll stay invisible to the vault’s readouts.
