## Summary Introduces a “ghost commit” workflow that snapshots the tree without touching refs. 1. git commit-tree writes an unreferenced commit object from the current index, optionally pointing to the current HEAD as its parent. 2. We then stash that commit id and use git restore --source <ghost> to roll the worktree (and index) back to the recorded snapshot later on. ## Details - Ghost commits live only as loose objects—we never update branches or tags—so the repo history stays untouched while still giving us a full tree snapshot. - Force-included paths let us stage otherwise ignored files before capturing the tree. - Restoration rehydrates both tracked and force-included files while leaving untracked/ignored files alone.
