What
The armed fallback model is only used when it genuinely matches the target, instead of being pushed through a remapping helper first.
Details
- The remapping helper call is gone from this path.
- The fallback is used only when its normalised family matches the mapped target's family and it has not already been tried.
- Otherwise the code falls through to the regular resolution path.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
