;; boundary.sx — SX boundary contract
;;
;; Declares everything allowed to cross the host-SX boundary:
;; I/O primitives (Tier 2) and page helpers (Tier 3).
;;
;; Pure primitives (Tier 1) are declared in primitives.sx.
;; This file declares what primitives.sx does NOT cover:
;; async/side-effectful host functions that need request context.
;;
;; Format:
;;   (define-io-primitive "name"
;;     :params (param1 param2 &key ...)
;;     :returns "type"
;;     :async true
;;     :doc "description"

;;
;;   (define-page-helper "name"
;;     :params (param1 param2)
;;     :returns "type"
;;     :service "service-name")
;;
;; Bootstrappers read this file and emit frozen sets + validation
;; functions for the target language.
