AGENTS.md and PLAN.md were both carrying their own copy of the HTTP
surface, and the previous commit replaced those with a pointer to this
module doc comment -- which turned out to be missing ten routes that
exist: the four `/setups/{id}/importable*`, `/sessions/{id}/permission-mode`
and all five under `/models`. Naming it the source of truth is only worth
doing if it is one.
The two "later phases add" lines at the foot are gone. Setups replaced
`/hosts` in August and `/models` is the block just added above them, so
both were promising work already done.
cargo test (127), clippy --all-targets and fmt clean.
