Equal read counts hide mismatched mate identities · case 03

Equal read counts hide mismatched mate identities.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Each mate stream has unique read IDs; return paired intersection and symmetric-difference orphan IDs as sorted lists.

Why this case matters

A deterministic offline model of scientific workflow bookkeeping; the fixtures test provenance contracts without modeling instruments or biological inference.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
same size different mates	`{"orphans": [], "paired": ["b", "read3"]}`	`{"orphans": ["b", "c"], "paired": ["read3"]}`	Failed
