4. FAILURE DIAGNOSIS

Error	Cause	Fix
Depth profile shows nan values	Route extends beyond bathymetry grid	Expand GEE export bounds; check route CRS matches raster CRS
Route has gaps / discontinuities	Source shapefile multi-part geometry	Explode and sort by chainage; use gpd.explode()
Metocean extraction returns all zeros	Wrong variable name in NetCDF	Inspect ds.data_vars
OrcaFlex environment YAML fails validation	Depth profile non-monotonic	Sort profile by chainage; remove duplicate distances
Wells fall outside lease block	CRS mismatch	Ensure both layers in same CRS before sjoin
GEE export empty	AOI too small at requested scale	Reduce scale to match AOI size
