Updated comments: removed debugging comments.
Removed duplicate files

whitespace
validate result's lookup_hash

I caught bit by setting test_name manually instead of by using

fixed splitting bug and made it retain anno file headers
Resolve-attribute returns unique values, so count may not be the same
remove `genome model update build-requested`

Use `genome model build queue` instead of `genome model update
build-requested`.
