Download the deposit, run one command, and 43 Tier-1 scripts re-derive the design's numbers on your laptop — 43 OK, 0 failures, outputs matching the deposited CSVs.
The deposit ships its own verification harness: run_all.py executes every Tier-1 analysis — equilibrium, burn physics, kinetics, neutronics ledgers, power balance, even the LCOE table generator — and reports pass/fail against the deposited outputs. The certified line is 43 OK / 0 FAIL (with 4 external-code items skipped by design), and the suite has been re-certified after every revision of the series.
Reproduction is byte-serious: outputs are compared file-by-file, and when a reviewer-grade check found a single script whose rerun appended rather than rewrote its CSV, the bug and its fix went into the public record like everything else.
The cheapest due diligence in energy is rerunning our math — we made sure of it. Every journalist's 'how do we know?' has a literal answer: python3 run_all.py. Institutions that cannot audit a plasma can still audit a pipeline, and that is the trust bridge fusion has been missing.
