# Barrier

Put a clean absorb layer between the operator and the next hit.

## Overview

Use Barrier when the system can keep moving, but it needs a buffer layer to absorb the next impact.

This is the secondary Codex compatibility rendering of a hybrid battle-chip pattern with a shipping-now execution model.

Canonical chip family: Barrier
Codex shelf: Defense and Recovery
Provider target: Codex compatibility surface.

## When To Use

- A rollout, workflow, or review path needs temporary protection.
- The next hit is predictable enough to absorb with a wrapper or check.
- You want to buy time without freezing motion.

## Workflow

1. Identify the likely hit you need to absorb.
2. Place the lightest viable buffer in front of it.
3. Measure whether the barrier held or needs reinforcement.

## Deliverables

- A wrapper, guard, or validation layer.
- A short note on what impact it is designed to absorb.

## Guardrails

- Barrier is not a substitute for understanding root cause.
- Do not mistake a temporary shield for a permanent fix.

## Default Invocation

Use Barrier to add the smallest protective wrapper or guardrail that can absorb the next likely hit without stopping the whole workflow.
