Constant Summary

NO_OP_LAMBDA =

A NoOpProc is a shareable stand-in for an arbitrary Proc in the app graph. Some Rails code passes such values through &block, which calls #to_proc and then requires the result to be a real Proc. Return a frozen no-op lambda so the implicit conversion succeeds and the (side-effect-free) call is a true no-op, matching #call.

The lambda is a shareable constant (frozen at class load), NOT memoized on @_to_proc: NoOpProc instances are deep-frozen by Ractor.make_shareable during make_app_shareable!, so an @_to_proc ||= ... write would raise FrozenError on the frozen instance. A constant avoids the write entirely and is safe to share.
