OpenAI	HTTP 200, 366,631 bytes; `60d71355fe6f24897a29643556591ca18531a9580cead2296f0cfb33807c3c0f`	Raw hash changed from `61f1ab47d3bf78428e012db31475026922706c2d8b8781c994772dca0eaa43ca`; ordered visible article-text chunks are identical.

The text comparison excludes script, style and SVG content and normalises whitespace within each HTML text chunk. It is not a rendered-browser inspection, so changes outside that text remain possible. No new event-specific telemetry with sensor, unit, numerator, denominator and window appears in the accessible article text. The previously reported attempted exploitation, vendor defensive-deployment claims and AI-assisted defensive discovery/coordination remain separate; this read adds no observed successful compromise or attacker AI attribution. No public article is changed on this checkpoint.
