Records whether every bundled species has a supported default chromatic and achromatic model. Unsupported combinations remain explicit rather than being inferred from receptor-role labels.

Usage

species_channel_support

Format

A data frame with 16 rows and 5 columns:

species

Scientific name matching species_sensitivities.

channel_role

Either "chromatic" or "achromatic".

status

Either "supported" or "unavailable".

reason

Evidence summary or reason no default is available.

source

Literature citation or explicit package review decision.

Details

Every supported row must correspond to exactly one default in species_channels. Every unavailable row must have no default. Dataset generation and runtime validation enforce this invariant.

Examples

data(species_channel_support)
subset(species_channel_support, species == "Homo sapiens")
#>        species channel_role      status
#> 1 Homo sapiens    chromatic   supported
#> 2 Homo sapiens   achromatic unavailable
#>                                                           reason
#> 1                          Validated S M and L cone opponent set
#> 2 No adaptation-specific photopic or scotopic default is encoded
