//! Explicit IC 1.2.0 raw system calls used by the qualified Timers backend.
//!
//! Safe/unsafe signatures, callback ABI and trap behavior are upstream identities.
//! Callers retain callback environments, byte admission, reply/call ownership,
//! cycle policy and executor contexts. No entrypoint, global timer, scheduler or
//! executor is installed here. `stable64_size` observes pages; this boundary does
//! not allocate or own storage. Native compilation does not qualify IC execution.
