A const reference lowered to `val(itoa(g.a.ival), "int")` in emit_call.ludic — the initializer's raw integer bits, hardcoded as `int`. For a fixed const like `const X: fixed = 10.0` that yielded the Q16.16 bits (655360) typed as int, so every fixed comparison/arithmetic against it silently broke (it caused an infinite loop in runtime/native/numeric.ludic, previously worked around with inline literals). Fix: a const reference now emits its initializer expression via emit_expr(g.a), which carries the initializer's real type (E_FLOAT->fixed, E_BOOL->bool, E_STR->string) and even handles computed initializers. Every existing const is an int literal, for which this is byte-identical to the old immediate — the C-free bootstrap fixpoint and all golden renders are unchanged. - selfhost/tests/const.ludic + sh_case pin fixed/int/bool const behaviour. - runtime/native/numeric.ludic restored to named fixed consts (HUGE_TEN etc.), which the workaround had inlined; the numeric example (20 assertions) still passes, validating the fix under runtime splice. All suites green: x selfhost-test 31/31 (fixpoint holds, goldens byte-identical), x test 85/85, x test-tools 30/30. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
