After #1471 closes the node gap (25 nodes → 0), 20 edge diffs remain in parity-compare.mjs --langs jelly-micro:

Type 1 — WASM produces extra false-positive super-dispatch edges (wasm>0, native=0):

• super/super.js:B.m → B.m (self-loop, conf=0.8)
• super2/super2.js:B.m → B.m (self-loop)
• super4/super4.js:PostMixin.m → super/super.js:B.m (cross-fixture false positive)
• super4/super4.js:PostMixin.s, PostMixin.<static> similar cross-fixture edges
• this/this.js:f.h → f.g (incorrect this-dispatch)

Type 2 — Native produces edges WASM misses (wasm=0, native>0):

• classes2:G.constructor → prototypes3:a / spread:a (conf=0.5, dyn=1)
• fun:foo → super5:b / spread:b (conf=0.5, dyn=1)
• receiver-callee-mixup — o1.f/o2.f → g missing in WASM (2 each)

Type 3 — WASM produces duplicate edges native doesn't (wasm=4, native=0):

• receiver-callee-mixup:f → g appears 4x in WASM vs 0x native

Root cause investigation needed per engine. These are pre-existing gaps not introduced by the node fix.
