| 67 | |
| 68 | ``files_added``, ``files_removed``, and ``files_modified`` are always |
| 69 | populated in ``--json`` mode — agents do not need ``--stat``. |
| 70 | |
| 71 | ``structured_delta`` is the domain-specific symbol-level diff computed at |
| 72 | commit time. It is a ``dict`` with an ``"ops"`` key for code commits, and |
| 73 | ``null`` when no code-intelligence data was produced (non-code domains or |
| 74 | commits with no tracked changes). |
| 75 | |
| 76 | All keys are always present so agents can read them without ``dict.get`` |
| 77 | guards. ``"status"`` is always ``"ok"`` on success. |
| 78 | |
| 79 | JSON error schema (exit non-zero):: |
| 80 | |
| 81 | { |
| 82 | "status": "error", |
| 83 | "error": "<human-readable message>", |
| 84 | "exit_code": 2 |
| 85 | } |
| 86 | |
| 87 | When ``--json`` is active all errors go to stdout as JSON — no prose on |
| 88 | stderr. Agents should parse stdout and check ``status``. |
| 89 | |
| 90 | SemVer bumps are coloured: PATCH MINOR MAJOR |

| 92 | Filters: --since, --until, --author, --section, --track, --emotion |

| 97 | muse log -n 5 -- src/ # last 5 commits touching anything in src/ |
| 98 | muse log dev -- README.md # commits on branch dev that touched README.md |
| 99 | |
| 100 | Paths are matched as prefixes: ``src/`` matches ``src/foo.py`` and ``src/bar/baz.py``. |
| 101 | Exact paths match only that exact file. The ``--`` separator is optional when the |
| 102 | path cannot be mistaken for a branch name, but is always safe to include. |
