Nice improvement. Just a couple of minor cleanup suggestions.

For consistency with other default/implied names, I suggest wrapping
this in angle brackets: "<bytecode>")

For timestamp and size "incomplete" would probably be a better word
than "bad" in the error messages (since we're only checking the length
