SignalID has a new field 'quality' (verified ingame), which does not appear in the documentation yet: https://lua-api.factorio.com/latest/con ... nalID.html

It appears to be a `string?` field that is either nil for common quality or a string for any other quality.

in the mean time, SignalFilter is probably the type you're actually looking for!

Apologies if this is my misunderstanding.

When fetching signals via (at least) LuaEntity::get_signals, item signals are returned with a quality entry in the table, but this isn't described in the SignalID documentation.

For items, type is omitted as described; but you DO receive a quality if the quality isn't "normal".

Low priority I'm sure, but thought I'd get it on your list somewhere towards the bottom

Thanks for the report, this is fixed for the next release.
