Threat explainer

Community warnings

Redacted public lessons from real Guard protection moments.

Learn from blocked actions without exposing private work.

Published warning pages require deterministic redaction, moderation, noindex gates, and UGC link controls.

HOL Guard turns these moments into private receipts first, then public lessons only after redaction and moderation.
