Three critical stream adapter bugs landed overnight that fix silent data duplication, lost abort reasons, and hanging debug sessions.

The streams team shipped three fixes that address long-standing edge cases in the core adapter layer. First, `toWritable()` now correctly distinguishes between backpressure (where `false` means the chunk was accepted and the stream needs to pause) and rejection (where `false` means the chunk was refused) [1]. Previously it would retry the same data through the async writer, causing silent duplicates. Second, `broadcast({ signal })` and `share()` now propagate the abort reason to waiting consumers instead of completing cleanly [2], fixing a spec compliance gap in the Iterable Streams draft. Third, the debugger's probe mode now surfaces inspector failures instead of silently truncating reports when the target process hangs or severs the connection [4]. These aren't new features, they're the fixes that should have shipped with the initial implementations. npm also landed 11.15.0 [3] with dependency updates across the ecosystem. The Writable.toWeb() adapter picked up a race condition fix for synchronous drain events [5], particularly important if you run with highWaterMark set to 0.

Action items

→ Update Node.js in CI before next stream-heavy deploy to catch duplicate write cases nodejs/node [plan]
→ Test existing broadcast/share consumers with abort signals to verify reason propagation nodejs/node [monitor]
→ Upgrade npm to 11.15.0 with next release nodejs/node [plan]
