Calculation record
Verify a same-current covariant spatial carrier and its actual action.
The strictly timelike current domain and the inverse nature of the
connection are explicit. This does not derive spatial harmonic selection.
Research context
- Spatial mode tensors carried by the field's rest frame
A same-current rest-frame connection gives a covariant spatial tensor action and preserves zero-rotation-moment branches, while polarized principal modes expose a high-wave-number limitation of this completion.
Interpret numerical checks within the assumptions and limitations documented in these notes.
