tengu_foamy_spring is fail-open with fallback true; what it guards is not visible.

What

A gate named tengu_foamy_spring is read through a small registry that holds one reader. It returns true when no reader is registered, treats anything other than an explicit false as enabled, and stays enabled if the reader throws. The compiled fallback is true, so it is live unless remote config turns it off. What it actually guards is not visible from the gate code itself.

Evidence

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