//! Determinism + ordering tests for the assembler.
//!
//! The assembler module docstring promises:
//! > Output is deterministic: same manifest + blocks → byte-identical .md
//!
//! These tests actually verify that promise. Catches any accidental
//! `HashMap`-iteration leak, embedded timestamp, or non-stable sort.
