## Classification and evidence status

CONSTRAINT records an external requirement, CONSISTENCY agreement in a specified limit, and PROPOSED TEST an unfinished proposal. Category differs from evidence status: an external observation does not mean an ASD calculation has been completed. No new REPRODUCED or DISCRIMINATING entry is claimed.

| Test | Category | Status |
| --- | --- | --- |
| Transverse propagation speed | CONSISTENCY | CONSISTENT |
| Gravitational-wave and light arrival constraint | CONSTRAINT | UNTESTED |
| Free longitudinal spatial-wave search | PROPOSED TEST | UNTESTED |
| Longitudinal–transverse conversion | PROPOSED TEST | UNTESTED |
| High-field nonlinearity constraints | CONSTRAINT | UNTESTED |
| Directional metrological response | PROPOSED TEST | UNTESTED |

## Next data work

Fix parameters and observables before specifying source, propagation, reception and noise. Null results should give model-dependent exclusions. Continue through [OP-SD-005](/en/open-problems/space-dynamics/longitudinal-wave-detection) and [OP-SD-006](/en/open-problems/space-dynamics/source-coupling)。
