Seeds a shell from one visitor, so assembly restarts after an invalidation without an operator.
One sample is enough because nothing is served on it: assembleFor() assembles for a uid only
after verifyShellFor() passes. bumpGeneration() purges every shell, hence the need to reseed.
The harvest body is Drupal's complete BigPipe stream, so the caller returns it as the page.
