Five backends: BGE (FlagEmbedding), Qwen3 (generative yes/no logit scorer,
batched forward pass), CrossEncoder (sentence-transformers, covers mxbai-rerank
/ ms-marco / jina), Cohere (BYOK cloud), Remote (HTTP delegate to cf-reranker
service). Mock adapter for tests. 54 tests.
cf-reranker FastAPI service app (port 8011) — cf-orch manages as a process,
defaults to Qwen3-Reranker-0.6B.
make_reranker() auto-detects CF_ORCH_URL and routes to cf-orch cf-reranker
when set — cloud apps (Kiwi, Peregrine, Snipe) get remote Qwen3 reranking
with zero code changes. Local dev falls back to local BGE.
pyproject extras: reranker-bge, reranker-qwen3, reranker-cross-encoder,
reranker-cohere, reranker-service.
