Baseline after e663087:
- js/node/test/parallel/test-whatwg-readablebytestream.js failed strict state/error assertions.
- js/node/test/parallel/test-whatwg-readablestreambyob.js passed when isolated; the earlier unsupported count was an aggregate attribution error.
- js/node/test/parallel/test-whatwg-readablestream.mjs needed exact .mjs import lowering and a registered async regression because its Node mustCall callbacks are not bun:test registrations.
Completed in 6514279:
- strict getReader option validation with ERR_INVALID_ARG_TYPE and ERR_INVALID_ARG_VALUE
- logical default/BYOB reader lock and release behavior
- branded BYOB readers and requests with receiver/state validation
- pending byte reads, pull/error/close state, typed-view copying, partial queues, cancellation, and auto-allocation
- live asynchronous tee behavior without capture/live-queue aliasing or chunk duplication
- exact Node .mjs import lowering
- permanent registered async byte-stream tee regression
Acceptance evidence:
- registered async tee probe: 1 pass, 0 fail
- untouched WHATWG ReadableStream .mjs file: pass
- ordered positions 3630-3632: 3 files, 0 failed, 0 unsupported, 0 TODO
- ordered positions 3622-3645: 24 files, 0 failed, 0 unsupported, 0 TODO
- zig build: pass
- zig fmt --check and git diff --check: pass
All changes are Home-owned; the copied Bun test file remains byte-for-byte untouched.
