- T[K] resolves against record bindings, Object.hasOwn/assign lower over records and the DOM, fixed shapes take runtime-keyed writes with the miss trap, and string|RegExp unions narrow by instanceof - the width family gains the checked NARROW lift and the tuple-arm literal route (the option-table shapes) - island literals complete: get accessors, plain spreads, tagged templates with .raw, jsval ??, and call-time fence deferral for unlowerable members (lambda poisons defer too) - JS variadic rests under --dynamic bind the engine arguments array and re-invoke through apply; dyn values marshal into the island as the deep copy - corpus 2470-2476 pin every landing against the Node oracle on both backends
