• Pinned Wasmtime reentrancy fixture crosses a synchronous instance boundary

• testing: triage classified Wasmtime supplementary coverage gaps

• streams: Future.drop() before await on a deferred future is executed *after* the read — the disposed handle still drives the guest and yields the value; the same program with one extra turn rejects DroppedError blaming the write end

• resources: An async [Symbol.dispose]() on a host resource is neither refused nor observed — a rejecting one is an unhandled rejection

• resources: A throwing [Symbol.dispose] on guest-drop of a host resource poisons the instance but surfaces unbranded (not a Trap)

• streams: async-iterable cleanup failures after a clean guest reader drop are recorded as a producer "short stream" fault against an unrelated later call

• streams: drop()/cancelWrite() from inside a direct callback crashes the *peer's* rendezvous with an internal TypeError and poisons the guest; the misusing session resolves as success

• boundary: store.hostFailure is a single overwritten slot: concurrent host-import failures lose one and leave an export pending forever; sequential ones are cross-attributed
