Main now compiles minified npm packages (#1989), so ni-minified no
longer refuses and the island report lost its packaging class. The
fixture is now ni-bundled, whose build-transform markers still refuse it
as shipped.

Main now reports fenced sites in module top-level code under "runs at
startup"; the use of 'legacy' on line 22 is one of them.

A for-in or for-of loop stores its var binding only when it iterates. The
early-read analysis counted the loop as an unconditional store for every
later statement, so after a loop that ran zero times a closure read the
binding as initialized (typeof answered "string" where Node answers
"undefined"). The loop now settles the reads in its body; later reads
settle at the next unconditional store.
A program that declares a class reads and writes untyped properties
through helpers that first select the receiver's property bag. The bag
helpers return jsvals, so the helpers read the bag through js.toDyn;
keyed helpers test each class's key table between the key's coercion and
the read; and a program with subclasses normalizes the receiver
(value = %dyn.class.normalize(value)) at the start of each helper. The
inline-cache recognizer accepted none of these forms, so every property
site in such a program called its helper. It now looks through dyn/jsval
conversions of the receiver, accepts capsule branches before a keyed
helper's final read, and accepts a rebinding of the receiver to a bag of
itself. Plain objects and arrays then read and write through the site's
cache, as they do in programs without classes.
bench/dynamic-properties (new) exercises these sites.
ABI 5 takes a load function from the bootstrap's dispatcher; without it
the smoke program's start fails with an incomplete dispatcher.

Main's FinalizationRegistry took handle tag 72, so the Node island
handle moves to 73. Island handles keep their instanceof path in the
new scr_bytes_instanceof_at.

The libnode packs' smoke program (#1684) still used the pump/alive/
backend_fd entries that the hosted loop (#1696) replaced, so every
Build libnode pack job failed to compile it. It now provides the full
host table and dispatcher and runs Node's event loop once after starting
the asynchronous calls, as the runtime does at the end of a program.
