• a.method.call(b) on a foreign class instance uses the receiver's capture environment

• jsfields fix-forward: binarytrees_plain +0.64% (check() pays one extra instruction per call; share the receiver handle across a memo run)

• perf: typed-array element access goes through js_dyn_index_get/set with GC barrier and string check; int32 elements compared generically
