/*
  Property tests for the Set Name behavior slice.

  These assert useful invariants that unit tests cover only at a few fixed
  points. The validation, counter-conservation, setInput round-trip, and
  broadcast-failure invariants are shared with the Memo post slice and live in
  behavior-helpers.js; this file supplies the Set Name specifics.
