Qualify directional acceleration inside the native enclosure
The static force component passed all 24 source/domain controls. The new propagation candidate changes only the source of acceleration-change bounds: an immutable, source-bound directional acceleration interval replaces the training-conditioned interval. The original dynamics, native predictions, physical bounds and 27 physical plus 24 shared-error columns remain. Original shared-error caps and acceleration remainder are preserved.
The directional interval uses exact force calibration and rotation inequalities, with a declared 1e-10 m/s² numerical margin. Its physical-domain certificate must match the complete source reference and domain. The candidate still carries the original remainder; the new value range must not be treated as a Taylor error. It uses no training observations or known calibration to construct its bounds.
Reuse all 24 original native qualification inputs and acceptance limits: center and independent stationary-pose agreement within 1 micrometre; all 162 derivative columns checked at step .002 within 20 micrometres per normalized coordinate; all original nonlinear probes within the supplied remainder plus the existing 10 micrometre arithmetic margin. Every common-error column remains mandatory. The new candidate and original engines are separately frozen.
Finite allowance: 24 identities, 78 native evaluations, 19,632 native packet visits, 348 bounds, 348 directional certificates and 15,072 bound packet-steps (two passes per packet). Four workers use one numerical thread each. Each bound retains its cooperative 60-second ceiling; the overall ceiling is 600 seconds. No retries, extensions, process signals, original aircraft/ESA reads, observed fits or optimizer starts. Reserve each native evaluation and bound before it runs. Preserve all source/input/environment hashes, charges and failures.
A fully passing result permits a separately frozen complete prediction-method comparison. It does not establish recording-scale usefulness, a whole-program floating-execution enclosure or calibrated observation coverage.
