     "response.solve": "The fix is complete. Here's a summary of the change:\n\n**File changed:** `django/db/models/fields/__init__.py`\n\n**Change:** In the `DurationField.default_error_messages['invalid']` string, the format description was corrected from:\n- `[DD] [HH:[MM:]]ss[.uuuuuu]` (incorrect — implied hours were optional but minutes depended on hours)\n\nto:\n- `[DD] [[HH:]MM:]ss[.uuuuuu]` (correct — seconds are mandatory, minutes are optional, and hours are optional only when minutes are provided)\n\n**Rationale:** Looking at the `standard_duration_re` regex in `django/utils/dateparse.py`, the parsing logic is:\n1. `(?P<seconds>\\d+)` — seconds are **mandatory**\n2. `(?:(?P<minutes>\\d+):)?` — minutes are **optional** (preceding the seconds)\n3. `((?:(?P<hours>\\d+):)(?=\\d+:\\d+))?` — hours are **optional**, but only when followed by both minutes and seconds (the lookahead `(?=\\d+:\\d+)` enforces this)\n\nSo `14:00` parses as 14 minutes and 0 seconds (not 14 hours), which matches the corrected format `[[HH:]MM:]ss`.",
