What
An agent started by a workflow used to always take the main loop's model when none was given. It now consults a model resolution step first and only falls back to the main loop model when that step says "inherit". An explicit model on the call still wins.
Details
What the resolution step reads, and so what makes it return something other than "inherit", is not visible in the shipped code.
Evidence
N !== "inherit" ? N : F.options.mainLoopModel
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
