Yes it is explicitly written in the rules. Dermal armor is listed under cybernetic enhancements in gear. Armor is listed under armor in gear.
Dermal plating isn't armor, it's a cybernetic enhancement, that's not an interpretation, that's what's written.
Is it specifically and explicitly written somewhere that they're different sources because dermal plating is cybernetics while heavy assault armor is armor, or are you implying that because of your interpretation of the rule?
You're not understanding my question. I'm not asking if one is cybernetics and one is armor. I'm asking if there is some place in the book that explicitly states that all armor is considered a single source.
You're using the example in a strict literal interpretation as the rule, it isn't. The previous sentence tells you the rule same sources of soak don't stack. A suit of heavy armor and subdermal plating are different sources of soak and therefore stack. A suit of armor represents a single source of soak and therefore you can't stack them. You're on the right page.
Can you show me where the rules say "all armor counts as a single source"? Can you show me where it explicitly says that heavy assault armor and heavy clothing are both from a single source?
