Mixed-script domain label — homograph attack (Latin + Cyrillic/Greek in one label)
mixed-script-domain
What this tier means
High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.
How Gorganizer detects this
Sender domain has a label mixing ASCII Latin letters with characters from another script (Cyrillic, Greek, Cherokee). This is the classic homograph attack signature — attacker registers a domain like "pаypal.com" where the `а` is Cyrillic (U+0430) but the other letters are Latin, visually indistinguishable from "paypal.com". Legitimate IDNs always use a single script per label (all-Cyrillic, all-Greek, all-Japanese). Complementary to the `punycode-domain` signal, which catches the same attack when the domain is punycode-encoded (xn--); this one catches it when the domain reaches us in raw Unicode form.
False-positive guard
Every signal in Gorganizer feeds a multi-module score — never a sole verdict. This is a threat-tier signal — it adds a strong contribution to the trash score. The full pipeline still requires convergence across multiple modules + a margin over the safety floor before deletion happens, and Gmail's trash (30-day recovery) is always used — never permanent delete.
About the scoring engine
Gorganizer's scoring engine emits over 1,800 signals across six modules — headers, sender, subject, body, attachments, and structural metadata. Every email is scored by every module independently; the final verdict requires multiple modules to agree and the trash score to beat the safety floor by a margin.
Sacred safety guards — never delete starred emails, replies, calendar invites, receipts/invoices, or attachments — apply unconditionally regardless of any signal.
