Phase-B axis scope gate
Decision: Current Phase-B maps are useful for diagnosis, but sagittal H-F is not reportable from the current XZ/XY projections. True sagittal H-F requires YZ.
Keep: Transversal R-L R=2/R=3 in XZ remains a reportable candidate after visual review. XY remains diagnostic/secondary.

XZ contains X=R-L and Z=A-P; R-L acceleration lies in this plane. R=3 remains stricter and needs stronger caveat. |

True sagittal H-F should be evaluated in YZ. XZ misses H-F; XY contains H-F but is not sagittal. |

True sagittal H-F should be evaluated in YZ. R=3 is especially sensitive and must not be reported from a substitute projection. |
