Both kiosks admit a check-in or check-out with no login when the caller sits in a configured network. The subtraction that makes that safe was missing. A reverse proxy normally sits ON the plant network a site enters in the allowlist. When the proxy forwards nothing - misconfigured, or something bypassed it - the request arrives wearing the proxy's own address, which matches the allowlist, while carrying no evidence whatever about who sent it. That is the one case that has to refuse, and it was being admitted. The previous fail-closed test only looked closed because the proxy in it happened to sit outside the range. Addresses that belong to the path are now subtracted before the allowlist is consulted: loopback always, since no site's kiosk is the server itself, plus whatever the site declares as its proxies. USB and printedparts get the same treatment - they had diverged for no reason anybody chose. Three more, same surface: A range that admits everybody can no longer be saved by accident. 0.0.0.0/0 and ::/0 are refused outright, anything wider than a site plausibly needs is refused unless an explicit override is set, and the refusal says why. The kiosk token no longer travels in a URL. The provisioning link carries a single-use setup code redeemed on first open, so the token stays out of browser history, referrers and proxy logs. The route is declared public deliberately: the secret is the code, the way a password-reset link is the secret. The badge-to-name lookup is bounded. It answers without a login and is now reachable from a whole network rather than one screen, so a source that keeps missing gets refused rather than being allowed to walk the directory. On by default, budget and kill switch are settings. All four new settings carry controls on their settings pages. A setting that can stop the kiosk, or widen it, must not be reachable only by hand-editing rows. The installer's client-IP advice is corrected: it described the opposite of what the shipped waitress flags do, and named only GE-Enforce as the thing that breaks when the rule is absent, when the two kiosk allowlists depend on it too.
