# Threat Model Gate
## Overview
Security cannot be added later. Features that touch user data, system boundaries, or trust relationships require threat modeling during planning — not after code is written.
## Core Principle
**Every feature that handles user data, authentication, or system boundaries requires explicit threat modeling before implementation.**
"We'll secure it in the next sprint" is a commitment that never gets honored. The cost of retrofitting security is 10x the cost of designing it in. Threat modeling during planning is the minimum viable security practice.
## When to Activate
