Who consumes what

Humans review the rendered book; AI agents work from the WAD data and the specs decomposed from it.

The book is for humans: wcl wdoc serve wdoc/book/main.wcl --comment renders the live twelve-chapter site with click-to-comment review (comments land in a comments.wcl sidecar; the review handshake blocks an agent until the reviewer sends them).

AI agents don't get a rendered book — they work from the WAD itself (the raw data/*.wcl files are typed and legible) and, for implementation work, from the specs decomposed out of it. A strong model can implement straight from the WAD; weaker coding models are handed generated specs scoped to what they can hold. See the spec workflow.
