Retrieval metrics and vector-DB shape — recall@k, MRR, and why the filter runs before the search (step 5/7) · context and retrieval

promptdojo_

The multiple-choice bug, live. search ranks every tenant's rows, slices the top-2, THEN filters by tenant — so acme gets an empty list while its own refund policy sits in the index at 0.81.

Rearrange the function so the tenant filter runs before the rank-and-slice.

Expected output:

['acme/refunds', 'acme/sla']

The break is on lines 10, 11 — but read the whole snippet first.
