Research direction

Start with the JavaScript IPC file writer and compare its output with the embedded-stream requirements in the linked Columnar format documentation. Review the validation added in pull request #43834 and reproduce the failure; done means a JavaScript-written IPC file contains a Schema message and passes embedded stream validation.

Description

Type: bug
Describe the bug, including details regarding any error messages, version, and platform.

The format guarantees that each IPC file embeds a valid IPC stream in order to allow readers to ignore the Footer, skip the file's leading magic, and reuse a stream reader.

https://github.com/apache/arrow/pull/43834 adds validation of the embedded IPC stream and files written by JavaScript fail. When writing IPC files JavaScript seems to omit the stream's Schema message rendering the file unreadable by a stream-only reader.
