 **MEASURED.** `tools/simulate.mjs`, 2000 runs each, seed 11, against the cast of six —

-> ⚠ **Correct as of 5450521, and due for re-measurement.** The harness is being reworked —
-> hit location by species rather than body plan, armour per location rather than one
-> scalar, flyers grounded by a lost wing — and both baselines are being re-recorded, so
-> per-creature figures will move. **Re-run the command below and re-pin these numbers
-> before the scenario is called convention-ready.** The shape of the finding is not in
-> doubt (the understudy is harmless, the column is lethal, and the curve between six and
-> ten is steep); the decimals are.

 **Read these as a floor.** The harness does not model bleeding, Panic, Coherence, cover,
 range bands or fire modes, and every one of those makes a fight worse for whoever is
