pyr0ball	185057d8ca	feat(reranker): full adapter suite + cf-orch auto-routing (closes #54) ... 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.	2026-04-26 09:04:39 -07:00
pyr0ball	82f0b4c3d0	feat: cf_core.reranker — shared reranker module Phase 1 (#54) ... Trunk + text branch + BGE adapter: - base.py: Reranker Protocol, RerankResult (frozen dataclass), TextReranker base class with rerank() / rerank_batch() built on _score_pairs() - adapters/mock.py: MockTextReranker — Jaccard scoring, no deps, deterministic - adapters/bge.py: BGETextReranker — FlagEmbedding cross-encoder, thread-safe, batched forward pass via rerank_batch(); graceful ImportError if dep missing - __init__.py: rerank() singleton, make_reranker(), reset_reranker(); CF_RERANKER_MODEL / CF_RERANKER_BACKEND / CF_RERANKER_MOCK env vars - pyproject.toml: reranker-bge and reranker-qwen3 optional dep groups - 20 tests, all passing Architecture ready for Phase 2 (Qwen3TextReranker) and Phase 3 (cf-orch remote backend). ImageReranker/AudioReranker branches stubbed in base.py docstring.	2026-04-21 12:25:01 -07:00
