inspect_native_dispatch_metadata read pointer fields as stored bytes, so
chained-fixup images (the default since Xcode 13) decoded no classes, and
superclasses from other images were always unresolved.
- Decode LC_DYLD_CHAINED_FIXUPS pointer formats 64, 64_OFFSET, ARM64E,
ARM64E_USERLAND and ARM64E_USERLAND24 with import formats 1-3, and
interpret LC_DYLD_INFO bind, weak-bind and lazy-bind opcode streams.
- Name external superclasses from their _OBJC_CLASS_$_ binds.
- Decode class_ro_t baseProperties and __objc_catlist category_t records
(instance/class methods, protocols, properties) into objc_categories;
category methods carry their category name.
- Report the fixup encoding in a pointer_fixups coverage facet.
- verify:apple-dispatch builds the fixture with dyld-info and chained
fixups, plus arm64e on Apple silicon.

Foundation encodes `encode(_:forKey: "UID")` as a `$top` dictionary
whose single key is `UID`. The keyed archive projection treated every
one-key `UID`/`CF$UID` dictionary as a reference marker, so that root
became a malformed reference and the real link to its object was lost.
Treat a one-key dictionary as a UID only when its value is a number,
matching the binary decoder's UID shape and Foundation's XML `CF$UID`
rule; otherwise descend into it as an ordinary dictionary.
