/*
  Unit tests for the optimistic reply object builder
  (src/services/optimistic-reply.js).

  The reply form renders an optimistic reply immediately after a successful
  broadcast, before the thread is refreshed from the network. This module
  shapes that reply object so the shape is covered by unit tests and the
  React form stays a thin adapter.
