  "result": "I've written `solve.py` and run it on the sample data. It wrote `answer.json` with all 55 rows. I checked several rows by hand and they match the rules. The hidden checks and fresh runs haven't been run here, so the score isn't known yet.\n\n**Sample results**\n- Violations by angler: ana 15, ben 12.\n- Legal kept fish by species: BSB 5, FLK 3, STB 5, TOG 6.\n\n**Rows I checked by hand**\n- Row 10: 33.0 cm converts to 12.99 in, just under the 13 in minimum, so it's `undersize`.\n- Row 28: 40.6 cm converts to 15.98 in, under 16, so it's `undersize`.\n- Row 22: a tautog kept on 01\u201120 is `legal`, because that season runs from 10\u201115 over New Year to 01\u201131.\n- Row 34: ana already had 3 legal fish that day, so it's `over_aggregate`.\n- Row 37: ana already had 2 legal striped bass that day, so it's `over_bag`.\n\n**Choices where the spec was ambiguous**\n- **Rounding:** cm to inches uses exact decimals and rounds halves up, so float error can't flip a fish at a size limit. The spec doesn't say which way to round a value that lands exactly on a half.\n- **Unknown species:** a row with an unrecognised species is `unknown_species` and counts as a violation even if the fish was released, because the species rule comes first.\n- **Trimming:** extra spaces around all fields are ignored, including angler names. Column names also ignore case.\n- **File paths:** the two data files are looked up relative to the current folder first, then relative to the folder `input.json` is in.\n\nIt uses only the Python standard library and runs well within the 60-second limit.",
