| 5 | I JSON envelope schema — status, error, branch, path_prefix, duration_ms, exit_code |
| 6 | II Error payload shape — consistent {status, error, exit_code}; no prose in JSON mode |
| 7 | III branch field — reflects the branch HEAD resolved to |
| 8 | IV path_prefix echoed — agents can verify which filter was applied |
| 9 | V TypedDicts — _LsFilesJson and _LsFilesErrorJson exist with correct annotations |
| 10 | VI Docstring — documents all envelope fields |
| 11 | VII Data integrity — object_ids are sha256:-prefixed in all output modes |
