Source	Access and retained SHA-256	Delta from 16:00 UTC
Amazon Threat Intelligence	HTTP 200, 195-byte `Site Unavailable` placeholder; `5b131ca14aa96311d3432b0062c7443d3b0e6346ec279bd376a75f0a76bcd5d7`	Identical placeholder; article still inaccessible to this direct collector.
Cloudflare	HTTP 200, 305,077 bytes; `630e8de4bff8324345addf43f54a5ba5f5d47ea6526b789a9479a90861eac721`	Changed from 301,730 bytes and `3d0f90b29a5d79e364b79ce217eb2d05906662e0d6128efb076690839ac16f86`. Its `article:modified_time` advanced from 21 October 19:12:17.798 UTC to 22 October 19:09:42.850 UTC. Visible text changed in the defensive-rules section.
OpenAI	HTTP 200, 366,700 bytes; `61f1ab47d3bf78428e012db31475026922706c2d8b8781c994772dca0eaa43ca`	Changed from 454,210 bytes and `9f514ba974c936a9bd32c8184c6bc828b4738c12dd6074226f6b15a387c19ae0`; ordered visible article-text chunks remained identical after excluding script, style and SVG content and normalising whitespace.

Cloudflare's source revision, not a newly timed deployment. The 22:00 retained article renames seven Free and seven paid managed-rule descriptions from generic anomaly labels to PHP remote-code-execution labels naming CVE-2026-109618 and CVE-2026-109619; their displayed rule IDs remain the same. A sentence now says the Cloudflare Managed Response Firewall Default has been automatically deployed for customers on all plans, including Free, and points readers to a security-rules page to verify active response rules. The prior version instead listed one response rule ID as deployed and said the descriptions would be updated soon. The modified-time metadata dates a page revision, not a proved deployment time or independent efficacy measurement. The article's default-protection claim for WAF customers remains a vendor statement, not a count of protected sites.

This is a defensive-deployment claim revision, not new attack telemetry. The changed text supplies no event-specific request numerator, sensor denominator or observation window, and no count of successful compromises. The earlier Amazon-reported attempted exploitation and OpenAI's documented AI-assisted defensive discovery/coordination remain separate. Nothing in this read identifies AI use by an attacker. HTML text extraction checks the retained bodies; it is not a rendered-browser inspection. No public article is changed on this checkpoint.
