Three adjacent cells of the shared count surface still diverged from the rest; all now route through the same leaf+fold+narrow+diagnose path. 1. Aliased integer constraint bypassed the value-param range gate — only builtin constraint names matched intTypeRange, so Box(5_000_000_000) with `$K: Count` (Count :: u32) compiled and bound a truncated value. resolveValueParamArg (shared by both the struct AND type-fn binder) now resolves the constraint to its underlying builtin via canonicalIntConstraintName (Count -> u32, Small -> s8) before range-checking, so an aliased integer constraint behaves exactly like the builtin it names. 2. A named const with an expression RHS (M :: 2; N :: M + 1) did not fold as a count — moduleConstInt read only a literal RHS node. It now folds every const's RHS through the shared evalConstIntExpr, cycle-guarded (mutual / self cycles fold to null, not a stack overflow), and pass-0 pre-registers expression-RHS consts. N :: M + 1 == 3 at every consumer: dim (direct + alias), Vector lane, value-param (struct + type-fn), inline for. 3. Stateful resolveArrayLen still fabricated length 0 after a failed fold; it now returns null -> the .unresolved sentinel (no fabrication). The binding's lowering never reaches sizeOf (alloca defers it; hasErrors aborts first) and a field access on an already-diagnosed .unresolved value is poison-suppressed (emitFieldError), so a failed-fold dim emits ONE clean diagnostic with no panic. Regressions: examples/0146 (full positive matrix — every consumer x leaf form), 1135 (aliased u32 + s8 overflow), 1136 (direct non-const dim halts cleanly). The cascade cleanup also tightened 1502/1503 to one diagnostic. Unit test added for moduleConstInt expression-folding + cycle detection.
