# V138 clean face-depth flux / no temporary corrections

Base: V130 compile-fix baseline.

Kept:
- V129 CSV dip bulk apply button.
- V129 station_no 1500,1501,1502,1524 -> forecast/station id 49 override.
- V129 shallow coast damping removal.
- V130 Quick FF helper compile fix.
- V137 face-depth flux wave update using geometric face depth.

Removed / not included:
- V131 global attenuation removal, source-ramp shortening, and depth-efficiency relaxation.
- V132 land-reflection-loss experiment.
- V133 late residual damping.
- V134 Quick FF patch-center-depth experiment.
- V135 JESIM station local radius-2 sampling experiment; restored radius 1.
- V136 propagation-depth floor experiment.
- V141/V142 Okada group-span/area normalization experiments.

Main remaining physics change versus V130:
- The wave update uses face-depth flux coupling instead of center-depth Laplacian coupling, to reduce artificial blocking at abrupt bathymetry transitions without applying a shallow-depth floor.
