FA-93857 / Shift rostering labor rules / Member archive

Back-to-back shifts classified as overlapping · case 02

A shift that starts the minute the previous one ends is reported as an overlap instead of a short rest.

Case contract

Input shifts as [worker, start, end] absolute minutes and a minimum rest "HH:MM". For each worker, walk shifts by start time, comparing each start with the latest end seen so far (and that shift index): a negative gap is an overlap, a gap below the minimum rest is short_rest; exactly the minimum is compliant. Return [worker, earlier index, later index, kind] rows ordered by worker then start.

Why this case matters

Rest-period validation is the most common roster labor rule; errors either hide fatigue risks or block legal rosters.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: overlap containment only 1	`[["ben", 5, 4, "short_rest"], ["ben", 4, 3, "overlap"], ["ben", 3, 2, "overlap"], ["dev", 1, 8, "overlap"]]`	`[["ben", 5, 4, "short_rest"], ["ben", 4, 3, "overlap"], ["ben", 3, 2, "short_rest"], ["dev", 1, 8, "overlap"]]`	Failed
