I guess it's a good thing that the F3 standard does not say "read this file and execute the instructions you find at the beginning", then?

The WASM encoders/decoders are embedded resources that exist as byte offsets in the file metadata, not header info.

Ok if you want to be pedantic, the standard says, "if you can't read this file, go to the offset and then execute the code you find" which isn't functionally different from what I said.
