Inputs to feed the chapter tools, and the book's own modeled numbers. All of it is
illustrative — arithmetic over published rates, or a sample artifact. None of it
is a receipt: that word is reserved for metered spend read off a real trace
(claude -p --output-format json). Your own runs are the only receipt.
