Review Guardrail Inversion

Your draft is bound to this exact source hash. If the term changes, the Review Desk will use a new storage key instead of silently attaching old decisions.

Definition

A situation where safety controls impede legitimate defenders more than determined attackers.
Decision for Definition

Plain-Language Explanation

A control may block authorized testing, monitoring, repair, or response while capable attackers bypass it or use channels the control does not cover.
Decision for Plain-Language Explanation

Why It Matters

Controls should be evaluated by their real effect on both defense and attack. Burdening defenders can reduce visibility and response without meaningfully reducing adversary capability.
Decision for Why It Matters

Example

A security policy prevents internal analysts from testing a dangerous prompt pattern, while attackers reproduce the same behavior through local models and unmonitored tools.
Decision for Example

Common Misconception

Guardrail inversion does not mean safeguards are generally harmful. It identifies a particular asymmetry that calls for redesign, authorized pathways, and evidence.
