The agent's default cwd is the temp/ subdirectory, where git resolves
'-- <file>' pathspecs relative to cwd. Fed the root-relative paths that
'git diff --name-only' prints, 'git checkout upstream/main -- <file>'
fails with "pathspec did not match", breaking the working-tree
reconcile steps of /update. The prompt now tells the agent to run every
git command from the repo root (_ROOT), in both EN and ZH.
