First iter of milestone 24 (Show + print rewire). Wires two new heap-Str-producing primitives parallel to hs.4's int_to_str / float_to_str: - runtime/str.c gains ailang_bool_to_str(bool) → heap-Str "true" / "false" and ailang_str_clone(const char *) → memcpy'd heap-Str copy. Both use the existing str_alloc slab helper. - builtins.rs + synth.rs install the two signatures lockstep with ret_mode: Own; str_clone carries param_modes: [Borrow]. - IR-header preamble gains two unconditional `declare ptr @...` lines; Emitter::lower_app gets two new arms; is_static_callee whitelist extends with the two names. - Five IR snapshots regenerate for the two new declares. - Pre-existing-drift fix: int_to_str row added to builtins.rs::list() (hs.4 installed env.globals entry but missed the list() row). Substantive deviation flagged by orchestrator (DONE_WITH_CONCERNS): builtin signatures registered in uniqueness.rs::infer_module and linearity.rs::check_module_with_visible (8 LOC × 2 files), symmetric to iter 23.4-prep's class-method registration in the same globals maps. Without this fix str_clone's param_modes: [Borrow] is invisible to the App-arg walker, src_heap walks as Position::Consume, the scope-close ailang_rc_dec is gated off, and the str_clone_cross_realisation_uniform_abi test's plan-literal `frees == 3` assertion does not hold. The fix is the substantively correct repair, not a design departure. 9 new tests: 2 builtins-install unit, 2 IR-shape unit pins, 5 E2E (2 RC-stats, 2 stdout-smoke for both Bool branches, 1 cross- realisation). 4 new .ail.json fixtures. Full cargo test --workspace: 513 passed, 0 failed. bench/compile_check.py: 24/24 stable. bench/cross_lang.py: 25/25 stable.

"doc": "Iter 24.1: cross-realisation invariant for str_clone. Clones a heap-Str (produced by int_to_str 42) AND a static-Str (literal `abc`); both clones produce fresh heap-Str slabs that print their input bytes. Pins the uniform-consumer-ABI claim — str_clone only reads the len-field at offset 0 plus the bytes plus the NUL; it never consults the (absent for static-Str) rc_header. RC stats under --alloc=rc: allocs == 3 (int_to_str output + two str_clone outputs), frees == 3, live == 0.",
