Module paths 

Path resolution for the per-workspace snapshot side-repos.

Snapshots live in ~/.zagens/snapshots/<project_hash>/<worktree_hash>/. The two-level hash split lets us snapshot multiple worktrees of the same project independently — git worktree list users won’t get cross-talk between feature branches.

Functions

ensure_snapshot_dir

Ensure the snapshot dir exists on disk and return its path.

snapshot_dir_for

Compute the snapshot directory for a given workspace path.

snapshot_dir_with_home

Same as snapshot_dir_for but with an injectable home directory. Used by tests so we never touch the user’s real ~/.zagens/.

snapshot_git_dir

Resolve the .git directory inside the snapshot dir.
