There is nothing for "the server" to know. Thus, gutting the introspection.
By appending `filter(false)` to the bytecode, you have a traversal that returns
nothing. Which is exactly what you want. No need for the receiving/executing
engine to reason about anything. A 3-line change to `iterate()` would do the
trick.---
