FA-94004 / Shift rostering labor rules / Member archive

Fortnight rest window slices thirteen days · case 04

A day off on the fourteenth day of a window is ignored, producing false shortfalls.

Case contract

A day pattern (W worked, O rostered off, L leave) and the count of consecutive worked days immediately before it. Any worked day that makes the streak exceed six is a streak violation; O or L ends a streak. Every 14-day window fully inside the pattern (each start index) needs at least two O days; leave does not count as a rostered day off. Return [kind, index] rows: streaks in day order, then windows.

Why this case matters

Consecutive-day limits and fortnightly day-off minimums are standard roster labor rules.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
