current repo policy outcome: exact per-product wavelength/FWHM metadata extracted from an official HE5 granule into a compact reproducible metadata snapshot

the staged metadata snapshot exposes the root-level metadata vectors copied from the official granule:
List_Cw_Vnir
List_Cw_Swir
List_Fwhm_Vnir
List_Fwhm_Swir
canonical ingest uses those arrays directly and excludes invalid non-positive placeholder slots
the staged metadata snapshot yields 66 valid VNIR rows and 172 valid SWIR rows for 238 canonical band-spec entries
the combined canonical ordering is VNIR then SWIR in native slot order, with subsystem and subsystem-band index preserved in shape_param_json
Gaussian realized curves remain optional derived products; no sampled native SRF curves are claimed from this source

this source is exact official product metadata for one granule, packaged as a compact HE5 metadata extract rather than the full source product
product-level wavelength and FWHM vectors should still be preferred for scene-specific analysis when multiple PRISMA products are available
the source metadata contains one trailing zero-valued SWIR placeholder slot, so the canonical band count is 238 instead of the nominal 66 + 174
