12 // keyless default falls through to the first configured chat provider, while
13 // explicit model choices remain strict.
14 //
15 // Semantics:
16 //
17 // - explicitRef == "": Config.ResolveNewSessionChatModel supplies the shared
18 // default/fallback policy used by boot and desktop. Non-chat models are
19 // never selected as a fallback.
20 //
21 // - explicitRef != "": the caller asked for this exact ref (--model flag,
22 // ACP session param, etc.). The ref must resolve AND be configured.
23 // There is no silent fallback — explicit choices that misfire must
24 // fail loudly so the user is not quietly rerouted onto a model they
25 // did not ask for. Plugin-namespaced refs (plugin/<plugin>/<provider>/
26 // <model>) pass through unresolved: they belong to extension sidecars,
27 // not the config catalog, and boot's merged resolver is their only gate.
