# `document`

std.document — typed document IR + deterministic render (design ⑦).

The model fills a typed `Report`; rendering to markdown is a pure, deterministic
function — no regex repair of freeform LLM markdown, and section/table placement is
structural. Replaces a hand-rolled `assemble_basic_answer`/`_assemble_report`.
`nl` is the newline separator, parametrizable so the same renderer can emit a
single-line form for tests or real newlines for output.
