I'm afraid that having only a tarball download for seeing the source code and having only CHM for documentation will seriously limit who can/will review your proposal. At a minimum, I'd suggest running phpDocumentor on your code and host the docs somewhere... including the --sourcecode runtime option will result in the docs containing highlighted sourcecode views, though actually making .phps files available would be better.
there are some slight inconsistencies as some of the messages being written to the log include timestamps and other don't...
other than that it looks good (there are a few phpcs/coding standards errors and warnings though).
