Lowering named helpers by the size of their registry at first use (%union.retag.N, %arr.map.N, ...), lifted closures and optional-chain locals by compiler-wide counters (%fnN, chain.N), generic instances by their instance count, and records and unions by creation order (rN, uN). Class expressions, mixin instances, function-local generics, non-exported namespace segments and some module globals carried the byte offset of their declaration. A name therefore depended on which unit lowered first and on the positions of unrelated code. Helpers, instances, records and unions are now named by a hash of the key they are interned by (keyedHelperName), and recursive records and unions by their printed type and declaration. Closures and optional-chain ids are named by their lowering unit, their structural position and a count per key within the unit. Offset-based names use the structural position: the chain of enclosing named declarations and the node's ordinal among same-kind nodes inside the nearest one, so an edit outside that declaration leaves the name unchanged. Two different keys with the same name throw an InternalCompilerError. The module lists its records and unions by id. The generated program is unchanged apart from these names and that order, and test:lowering-order now fails on any name difference.
