Markdown is an intermediate format between a writer and rendered HTML. It is easier to read, write and edit as a writer (or someone reviewing someone else’s writing intended for the web) before generating and serving HTML. It’s not a superset, it’s not a subset, and it’s not HTML, although you can include HTML tags within a Markdown document to include things Markdown does not provide coverage for. Which is to say there isn’t any such thing as “source Markdown” and “rendered Markdown”. Markdown is the source, HTML is the output, although you can make your own parser output to whatever you want.
