+Discovery: Settings path, then Program Files, then PATH. Missing git.exe means no badge. Git is not bundled. Status / View Changes lists porcelain paths. Diff is unified `git diff`. Commit stages checked files then `git commit --only`. Stage / unstage / discard, ours / theirs / mark resolved, continue / abort wrap `git.exe`. Fetch / fast-forward pull / merge pull / push use `GIT_TERMINAL_PROMPT=0`. No mergetool, stash, branch UI, or credential dialog. Failed fast-forward pull offers merge pull or a terminal.
