How to use this file
At this size, reading the whole body into memory instead of streaming it fails fast. For everyday tests, smaller files are enough.
A BIN of 4 GB exercises the same path when the format does not matter: web-server and PHP limits, proxy timeouts, memory, and whether the stored size is exactly 4 GB.
This is a valid BIN of the stated size, generated for testing — not a finished document.
