Context: A search for "Wedgwood blue jasperware vase 1970s" returns 200 eBay listings ranked by eBay relevance, which is noisy. Running trust scoring on all 200 is expensive. A reranker pass over the top-50 results against the user's search intent would surface genuinely relevant listings before the trust pipeline runs, reducing wasted trust-score calls and improving result quality.

Scope:

After initial listing fetch, rerank top-50 by (search_query, listing_title + description) relevance
Only pass reranked top-N to the trust scoring pipeline
Wire to cf-core reranker service once available (see circuitforge-core ticket)
Free tier: skip reranking or use 0.6B variant; Paid: 8B variant

Out of scope: Reranking by price or seller history (that is trust scoring's job).

Acceptance criteria: Fewer irrelevant listings reach trust scoring; user sees fewer obviously off-topic results.

Related: circuitforge-core reranker service (shared infrastructure).
