Runtime guardrails

• Why this is not broader than the packet evidence: Production reset is limited to blockquote UA margins; generated class margins remain more specific.
• Evidence discriminators preserved: blockquote in vertical stack with preceding/following siblings
• Nearby contracts preserved: explicit generated margin and sibling geometry remain authoritative

Attempt summary

Forensic candidate strengthened after independent test review; PHP and browser geometry contracts green.
