The gh-pages branch hosts the contents of this directory at https://$OWNER_NAME.github.io/$REPO_NAME/. The permalink for this webpage version is https://$OWNER_NAME.github.io/$REPO_NAME/v/$COMMIT/. To redirect to the permalink for the latest manuscript version at anytime, use the link https://$OWNER_NAME.github.io/$REPO_NAME/v/freeze/.

This directory contains the following files, which are mostly ignored on the main branch:

• index.html is an HTML manuscript.
• manuscript.pdf is a PDF manuscript.

The v directory contains directories for each manuscript version. In general, a version is identified by the commit hash of the source content that created it.

The *.ots files in version directories are OpenTimestamps which can be used to verify manuscript existence at or before a given time. OpenTimestamps uses the Bitcoin blockchain to attest to file hash existence. The deploy.sh script run during continuous deployment creates the .ots files through its manubot webpage call. There is a delay before timestamps get confirmed by a Bitcoin block. Therefore, .ots files are initially incomplete and should be upgraded at a later time, so that they no longer rely on the availability of a calendar server to verify. The manubot webpage call during continuous deployment identifies files matched by webpage/v/**/*.ots and attempts to upgrade them. You can also manually upgrade timestamps, by running the following in the gh-pages branch:

ots upgrade v/*/*.ots
rm v/*/*.ots.bak
git add v/*/*.ots

Verifying timestamps with the ots verify command requires running a local bitcoin node with JSON-RPC configured, at this time.

The manuscripts in this directory were built from $COMMIT.
