Dataset split: equal event times follow input order instead of record ID order · case 03

equal event times follow input order instead of record ID order.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

Rows [id,time] have unique string IDs; return IDs in chronological order, breaking time ties by full lexical ID.

Why this case matters

This toy split allocator makes membership rules explicit for reproducible evaluation fixtures.

One recorded failure
