Terminology update (2026-09): "backend" is now called OSAdapter. rte_<service>_backend_t is rte_osadapter_<service>_t, rte_<service>_register_backend() is rte_osadapter_<service>_register(), headers moved from rte_backend/ to rte_osadapter/, and the POSIX implementation is rte_posix_osadapter_* (Platform_OS_POSIX). The text below keeps the original wording as a historical record.

Status: Draft Date: 2026-08-02 Applies to: Platform_RTE, first abstraction layer (RBC core <-> Operating System)
