Module behavior 

OTP-shaped behavior callbacks — the typed slot of caixa.lisp that points at the .lisp files implementing the lifecycle.

See theory/INSPIRATIONS.md §II.3 for the prior-art frame (gen_server, gen_statem, gen_event). Authors implement the callbacks; the runtime owns init / message dispatch / terminate.

(defcaixa
  :nome     "my-service"
  :versao   "0.1.0"
  :kind     Servico
  :behavior ((:on-init         "lib/init.lisp")
             (:on-call         "lib/handlers.lisp")
             (:on-cast         "lib/handlers.lisp")
             (:on-info         "lib/handlers.lisp")
             (:on-state-change "lib/migrations.lisp")
             (:on-terminate    "lib/cleanup.lisp"))
  :servicos ("servicos/my-service.computeunit.yaml"))

Each slot is optional — caixas without explicit callbacks fall back to the runtime defaults (no-op init, raw HTTP dispatch, noop terminate). The StandardLayout invariant in layout.rs verifies every declared path exists on disk before the build.
