`google/gemini-3.1-flash-lite-preview` no longer exists: the AI Gateway retires `-preview` aliases when a model goes GA. Two paths referenced it. rerank-suggestions.ts calls the gateway directly for risk/vendor -> task auto-link reranking. Both callers in run-linkage.ts catch the 404 and fall back to raw cosine, so the breakage was silent — suggestions quietly regressed to the pre-reranker precision this module exists to fix. Added a regression test asserting the requested slug is GA, not a preview alias. The automation chat `modelId` values are inert (the enterprise-api chat route hardcodes its own model and ignores the body field), but they are updated so the two repos do not disagree on which model is in use.
…slug fix(app): use the GA gemini-3.1-flash-lite slug
