  "methodology": "GET https://steamcommunity.com/linkfilter/?url=https://{domain}&l=english, classified BLOCKED if the response contains \"Link Blocked!\" / \"flagged as potentially malicious\", CLEAN if it contains the generic \"You are leaving Steam\" / \"is not an official Steam site\" notice. This is the same method as link_filter_check.py, which produced steam_tos_assets/link-filter-results.json. A blocked main URL paired with a clean return host is a Link Filter split, not proof of a completed OpenID login or circumvention of an authentication ban.",
  "supersedes": "A prior file at this path (mode: playwright_authenticated) was INVALID: linkfilter_playwright_probe.py set the Steam sessionid cookie to a hardcoded literal string (\"probe_session\") instead of the real session token, and/or the rapid sequence of automated requests in one browser session triggered a universal fail-safe response from steamcommunity.com/linkfilter/ — every domain tested, including the google.com control, rendered as \"Link Blocked\", which is not a real result for google.com. That bug is fixed in the script for any future authenticated re-run, but this file replaces it with the already-validated unauthenticated method instead.",
  "caveat": "Rapid automated querying of this endpoint (>10-15 requests in quick succession from one IP) was independently observed to trigger the same universal-block fail-safe seen in the invalid authenticated file. The 11 results below were captured before that threshold was hit, and the 8 that overlap with link-filter-results.json (generated separately, 2026-09-19T03:20, properly paced) match it exactly — see the cross-check flag on each result. csgoempirelogin1.com / csgoempirelogin5.com / csgoempirelogin10.com (single-domain checks, no paired proxy) could not be re-verified this pass without re-triggering the rate limit and are intentionally omitted; do not re-add them without a fresh, paced check.",
