- There is a concrete runtime risk in
lib/utils.js:forEachEntrycan still throw if[Symbol.iterator]returns a non-iterator, because_iterator.next()is called without validating the returned value. - Given the issue is moderately severe (5/10) with fairly high confidence (8/10) and can cause a crash in iteration paths, this carries some user-facing regression risk before merge.
- Pay close attention to
lib/utils.js- validate iterator objects before calling.next()to prevent crashes on malformed iterator returns.

Added extra check for iterator.next() after bot review feedback. Prevents crashes when generator returns invalid iterator objects. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Fixes potential TypeError crash in
forEachEntryutility function when iterating over objects with invalid iterators.Problem
The
forEachEntryfunction didn't validate thatobj[Symbol.iterator]is actually a function before calling it with.call(), leading to potential crashes when:Symbol.iteratorproperty that's not a functionSolution
Added safety check using existing
isFunctionutility before attempting to call the iterator:
