Problem

hk fails to discover the git repository when used with YADM (or any bare-repo dotfile manager). YADM manages dotfiles using a bare repo at ~/.local/share/yadm/repo.git with GIT_WORK_TREE=$HOME, so there is no .git directory or file in the working tree.

All hk commands fail with:

Error: failed to find git repository

    Location: src/git.rs:112:20

and hk install fails with:

Error: No .git found in this or any parent directory

    Location: src/git_util.rs:11:24

This happens even when GIT_DIR and GIT_WORK_TREE are set (e.g., via yadm enter).

Expected Behavior

hk should respect GIT_DIR and GIT_WORK_TREE environment variables for repository discovery, matching the behavior of git itself. When these are set, hk should use the specified bare repo and work tree rather than walking up the directory tree looking for .git.

Current Workaround

Manually writing hook scripts into the bare repo hooks directory (~/.local/share/yadm/repo.git/hooks/pre-commit) and wrapping hk check/hk fix with yadm enter in mise tasks. hk install cannot be used at all.

Context

• Bare-repo dotfile managers are common: YADM, plain git --bare, chezmoi (git mode), etc.
• The standard git env vars GIT_DIR and GIT_WORK_TREE are the established mechanism for this.
• hk version: 1.42.0
• Both the libgit2 path (HK_LIBGIT2=1, default) and the git CLI path (HK_LIBGIT2=0) fail.

Affected Commands

• hk check / hk fix / hk run
• hk install / hk uninstall
• hk builtins (panics instead of graceful error)
