What this tier means

High-confidence threat indicator — phishing, impersonation, BEC, or scam pattern. Strong contributor to the trash decision.

How Gorganizer detects this

Phishing emails impersonating Linear (issue tracker) claiming a team workspace has been suspended or a subscription cancelled due to a billing failure, directing victims to a fake billing portal harvesting credentials and payment card data. Three-part detection: (1) Linear workspace / team / organization / subscription language, (2) workspace-suspended or billing-failed urgency, (3) restore / reactivate / billing-update CTA with off-linear.app link. Proofpoint 2025-2026 documented developer-tool SaaS impersonation campaigns; active campaigns targeting engineering teams confirmed. Score +3: narrower developer audience targeting compared to consumer-facing platforms, but high-value target given Linear's use in managing production engineering workflows.

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.
