the custom enclosure earns its keep here. built in standoffs, camera pockets, and sensor pods make more sense than a generic foam box when the whole payload is 491 grams, and it's useful that the insulation test is reported as mixed rather than oversold. after the near-landing loss, i'd mostly want a clearer single-track recovery plan next.
