DashScope's OpenAI-compatible rerank endpoint lives at
{base}/compatible-api/v1/reranks — PLURAL leaf, different base path from
the embedding surface (compatible-mode). Reusing llama-server-reranker
against DashScope forces users to hand-patch the recipe's '/rerank' leaf
in node_modules, which every upgrade silently reverts (and llama.cpp
genuinely serves singular /rerank, so changing that recipe would break
real llama.cpp users).
New dedicated recipe rides the v0.40.6.1 recipe-pluggable reranker path:
- id dashscope-rerank, base_url_default compatible-api/v1 (intl), ZE wire
- path '/reranks', default_timeout_ms 30s, 5MB payload ceiling
- models: only qwen3-rerank (live-verified 200; gte-rerank-v2 is rejected
by the compat surface with 'Unsupported model for OpenAI compatibility
mode', so it is deliberately not listed)
- separate recipe (not a reranker touchpoint on dashscope) because
provider_base_urls is keyed by recipe id and the two capabilities need
different prefixes — same topology as llama-server vs
llama-server-reranker
Tests: recipe shape smoke mirroring recipe-llama-server-reranker.test.ts
(path/timeout/payload pins, /v1/v1 concat guard, auth resolve, sibling
recipe isolation). bun test test/ai/: 322 pass / 0 fail.
