about

_constarg_probe.nx -- minimal repro lattice for debt 1785866425: a const IDENTIFIER passed as a function-call ARGUMENT arrived as 0 in nx_being_showcase (tm_vcol(i, BS_SKIN) painted black), while the same value built in let-locals passed fine. This probe enumerates the suspect axes -- const initializer shape (literal vs expression), value size, and use position (arg1/arg2/store/compare) -- so the compiler fix targets the REAL failing surface, not a guess. expect_exit: 0 when the bug is fixed.
