A clock button in the file viewer header lists the versions of a file whose project keeps a git history; picking one shows the file as of that commit, read-only, with a banner back to the current version. A past version is never served from the working tree: the whole repository is materialized at that revision (git archive streamed through tar into a size-bounded, immutable-by-rev cache) and every fetch — content, compiled LaTeX, markdown images, downloads — resolves inside that tree, so dependencies are contemporaneous with the file: a .tex compiles against its \input's and images of that moment. Backend: new git_versions module (repo discovery bounded by the workspace mount, host-git log/rev-parse/archive, extraction cache with oldest-first prune) + GET /api/file/versions and a rev param on GET /api/file (rev is the ETag; never X-Writable). Frontend: history mode in FileViewerBase shared by the desktop and mobile viewers — popover, banner, watcher paused while browsing, rev propagated to every /api/file URL it builds.
