nx_probe_caplim_float.nx -- MUST-REFUSE WITNESS (capability-limit voice, 2026-08-13): a float value into an INTEGER binding used to COMPILE CLEAN and silently store the raw IEEE-754 bit pattern (measured pre-fix: x held 0x3FF8000000000000, not 1, no diagnostic). EXPECT: COMPILE-FAIL citing "raw bit pattern" + the fixed-point (Q14) fix + the slug capability=float-int-boundary. The float LANE stays reachable: `let x: f64 = 1.5` compiles (the gauntlet's f64_let_control cell proves it).
