CORRIDOR is a deterministic way to answer one question

<aside> 💡

Can this system actually execute what it believes is viable — or is it already failing without knowing it?

Most systems don’t fail immediately,

They keep running while already failing.

The Problem

They:

• retry
• continue running
• appear stable

But they may already be incapable of success.

What CORRIDOR Does

• when a system crosses from viable to non-viable
• when behavior becomes structurally unsafe
• when continued execution makes things worse

The Core Insight

Every system operates in two realities:

Corridor (what it believes)

“This should work.”

Terminal (what actually happens)
