Long-record streaming and native arithmetic

6/6 controls pass; state: complete.

The reference controls compare the unchanged whole-array kernels with chunked predictions. Exact-pose errors remain separate from agreement between the calculations.

The exact-pose controls use zero angular increments and exactly representable periods/gravity. The reference cases retain the earlier nominal-300-Hz specified-field input. The first study’s absolute-pose failure is preserved and is not relabeled by a successful equivalence comparison.

Reference arrays/compiler/shared-library storage are outside the traced streamed working allocation. Predicted observations and derivatives are compared and discarded one block at a time. These generated controls do not establish observational accuracy, global rounding bounds or calibrated uncertainty.
