- Object.create(null) is a real null-prototype dictionary: inspect, toString, and deepStrictEqual answer Node's forms; the dynamic tier routes to the engine's own Object.create for live delegation
- Object prototypes fence by name in static builds — an own-copy stance is observably wrong under Node's empty-own-set answers and live proto mutations
- entries() and keys() walk any static array live in for-of heads and iterator-helper chains
- Object.assign(target, ...sources) packs spreads with JS's evaluation order before any copy, with V8's position-dependent error texts
