docs: git cherry cannot detect a squash-merged branch - #65
Merged
Conversation
CLAUDE.md told you to use `git cherry -v main <branch>` to tell a squash-merged branch from one carrying real work. It cannot: the squashed commit's patch-id matches no individual commit, so every commit shows `+` and a fully-absorbed branch reads as unmerged. Confirmed on D58's 13-commit branch, whose content was byte-identical to main. `git diff main <branch>` answers it directly — empty means absorbed.

CLAUDE.mdtold you to usegit cherry -v main <branch>to tell a squash-merged branch from one carrying real work. It cannot.Under squash-merge the single squashed commit carries the combined diff, so its patch-id matches no individual commit on the branch. Every commit shows
+— reading as "still carries work" when the branch is fully absorbed. Confirmed while cleaning up D58: all 13 commits showed+, whilegit diff main d58-menu-dismissalwas empty.git diff main <branch>answers the actual question directly: empty output means the content is fully inmainand the branch is safe to delete.Docs only — no code change, no changeset.
