Malformed download URLs are rejected before the second request, error bodies are read only up to a bound, the telemetry summary keeps structural dispatch for duck-typed results, and the BMP magic now requires a valid DIB header. Docs and design are aligned with the implementation, and new test wording is neutral.
Slow, opt-in, serial single-page documents built in the test itself. Covers the document entrance, the PDF text-recognition fix, and that corrupt documents do not open the breaker.
