OpenCode Go (and OpenCode Zen) showed only a subset of the models they serve in the desktop/CLI model picker — e.g. opencode-go rendered 13 of 19, silently dropping minimax-m3/m2.7/m2.5, glm-5/5.1, deepseek-v4-flash. Root cause: the picker dedup in build_models_payload strips any model from an aggregator row that overlaps a user-defined provider's catalog (so a local proxy isn't shadowed by OpenRouter). It gated on is_aggregator(), which is True for opencode-go/zen because their flat /v1/models returns bare IDs the model-switch resolver searches. But those are flat-namespace RESELLERS, not routing aggregators — every model they list is first-party, so deduping them against a user proxy that happens to serve a same-named model guts their own catalog. Fix: add is_routing_aggregator() (True only for true routers like OpenRouter and custom:* proxies; False for opencode-go/zen) and gate the picker dedup on it. is_aggregator() is unchanged so model-switch flat catalog resolution keeps working. Both desktop entry points (model.options JSON-RPC and /api/model/options REST) and hermes model share build_models_payload, so all surfaces get the full list. Fixes #47077
