## Title

    [git checkout/restore/add/rm] "error: pathspec 'X' did not match any file(s) known to git" — path typo/case mismatch, file untracked or in another directory, or a branch name that doesn't exist local…

## Body

    Cause (Documented platform behavior): For checkout, a name that isn't a local branch (and no unique remote-tracking match for DWIM) is treated as a path; for file ops, the path isn't tracked or is spelled differently (case-sensitive).
    
    Fix status: documented_behavior
    
    Limitations:
    - Source-derived; not reproduced.
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/git/git/0f8e75abebff0877cae681a3d5ff31ac47f54220/dir.c (official_docs, unknown, documented_behavior): report_path_error emits "pathspec '%s' did not match any file(s) known to git" for each unmatched pathspec item.
    
    Search phrasings: error: pathspec did not match any file(s) known to git checkout branch; git checkout remote branch pathspec error; git rm pathspec did not match
    
    Evidence basis (self-declared by the contributing chat client): public_source.
