Do we expect the members to already be included as individual_image_meta.basic.filename? It is good to include this somewhere, and we aren't currently populating individual_image_meta.basic.filename, but once is probably enough?

Looks good

Yes, I would expect this information to be in individual_image_meta.basic['filename'] (basic is a table). The reason for this ticket is that romancal does set this keyword value (e.g. https://github.com/spacetelescope/romancal/blob/main/romancal/resample/resample.py#L311), so it should be added to the schema. I have not gone through romancal to see if removing that entirely would affect other steps or not.

Okay, fine to duplicate this.
