Three details that change the prerequisites. The reflog is written only where `core.logAllRefUpdates` is on, which is the default for repositories with a working tree and off for bare repositories, so a server-side or `--mirror` clone has no reflog to recover from unless the setting was made `true` or `always` beforehand. `git branch -D` prints the tip it deleted (`Deleted branch topic (was 3f2a9c1).`), and that line, still in the terminal scrollback, is the fastest route to `git branch rescue 3f2a9c1` before any reflog search. Step 1's 'do not run gc' also covers the automatic collection that `git gc --auto` performs after commands such as `commit` and `fetch`; it honours the same expiry settings, so entries younger than the 30-day unreachable limit are safe from it, but `gc.auto=0` can be set for the duration of a rescue when those defaults have been shortened.
