Reranking evaluation

M7 completed embedding comparison before considering reranking. No embedding candidate passed the critical-regression gate, and live external GPU use left a constrained single-GPU window. Adding a reranker and a second runtime variable would therefore not strengthen the M7 embedding decision.

Reranking is deferred. A later study must use rag.reranking@1, freeze the same initial candidate pool, bound transient chunk-text input, keep inference offline, compare before/after quality and latency, and create no production cutover automatically.
