The earlier fixed-spin-seed results are shown as restricted controls; ordinary tritium is recalibrated in each space. Two-body observables and ordinary tritium are fitted; neither helium binding is fitted. Error bars show only the last basis change, not physical uncertainty. The source Volkov and independent radial controls are supplemented by off-diagonal spin tests and exact nesting of the restricted space. In the last panel only the nn interaction changes; its input is calibrated to the infinite-volume pole, and the three-body force is not refitted. This is not the STM regulator convention, a field prediction or a four-body reaction calculation.",
