Hi,
" characteristics / edit " is for the edition of the characteristics ; you also have " characteristics / add " for the right to create new characteristics.
" characteristics / values / edit " (or add) is the ACL regarding the values in the characteristics.
Now about the product edition ; you have also rights :
" product / edit / characteristics " - to allow the user to assign a characteristic to the product (so to activate the variant system).
" product / edit / variants " - for the creation of variants.
" product / variant / ... " - for the available fields available during the edition of the variants.
