Each line's\nlength is checked before its columns are trusted, every error is reported\nat once - with what stopping at the first error would have said - and pay\nis added up by department in whole cents. It starts with nine lines, five\nof them bad.\n\n- `main.eml` - the menu, the ruler, the checks, the report, adding and\n  removing lines\n- `records.eml` - the columns, the field checks, the check of all lines,\n  the first error, and pay\n\nHow each part works:\n\n- A line is exactly 42 characters: id in columns 0-6 (six digits), name\n  6-26 (letters, spaces, - ' and .), department 26-30 (four capital\n  letters), hours 30-35 (like 037.5, at most 168.0) and rate 35-42 (like\n  0025.50, more than 0).\n- As the corpus case `fixed-width-record-parser` warns, a short line still\n  slices without complaint - into wrong fields. So the length is checked\n  first, and a line of the wrong length is reported on its own; its\n  columns are not read at all.\n- As in the corpus case `schema-validator-all-errors`, every error of every\n  line is listed, not just the first: one round of fixes instead of one\n  per error. The program also shows the single error that stopping at the\n  first would have reported. A repeated id is an error on the later line.\n- Pay is hours (in tenths) x rate (in cents) / 10, rounded half up to the\n  cent: 42.5 h x 31.75 = 1,349.375, paid as 1,349.38. Only good lines are\n  paid, by department and in all.\n\nWhat is checked: menu choices 1 to 6; a new line of any text (it is added,\nwith its errors listed); a line number that exists; at most 20 lines. An\nempty answer cancels.\n\nSessions: `sessions/basic.in` gives:\n- the nine lines under the ruler, and their seven errors on five lines;\n- the pay report: SALE 1,845.00, TECH 2,466.58, 4,311.58 in all;\n- a good line added for Jo Kim and paid; the short line removed, leaving\n  six errors on four lines.\n\n`sessions/bad-input.in` gives:\n- menu choices 0 and x;\n- \"abc\" added (3 characters), and a line with five errors in one go;\n- line numbers 0, 99 and x to remove, then cancels;\n- the check of all eleven lines: 13 errors on 7 of them.\n\nBuilt on the verified corpus cases `fixed-width-record-parser` (check the\nline before trusting its slices) and `schema-validator-all-errors` (every\nfailure at once, against stopping at the first).\n",
