Vector retrieval: Per-shard top results are concatenated without global ranking · case 04

Per-shard top results are concatenated without global ranking.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Shard lists contain [id,score], unique IDs; globally return top k by score then ID.

Why this case matters

An offline vector retrieval toy model isolates one ranking contract from embedding generation, storage, and serving.

One recorded failure

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