What actually exists in the code?
Not what the landing page promises. Not what the README describes. Not what the agent says it implemented. What exists.
Generating code became easy. Deciding what deserves to survive became the hard part.
A controlled public sample from the bilingual book about code review, reality checks, and governance in AI-first projects.
What actually exists in the code?
Not what the landing page promises. Not what the README describes. Not what the agent says it implemented. What exists.
Four realities, two operational extensions, and one decision layer.
A file can exist in the repository and still not exist in the product. A component can be well written and never rendered. A route can be declared and never reached. A provider can be configured and never used. An endpoint can respond locally and still not participate in the real flow. A test can exist and still protect nothing important.
The common mistake is treating presence as proof.
Presence is only inventory.
Reality requires participation.
Code participates when it has a verifiable relationship with a real flow: it is called, rendered, reached, receives data, transforms state, produces an outcome, handles error, sustains a promise, protects a rule, or removes ambiguity.
If none of that happens, perhaps it will be useful one day. Perhaps it is an idea. Perhaps it is a draft. Perhaps it is residue. Perhaps it is decoration. But it is not yet operational reality.
Many products seem to work because someone tested the happy path.
The happy path is simple: correct user, correct data, correct environment, correct connection, correct key, correct response, correct expectation.
But real products live outside that comfort.
The user makes mistakes. The browser reloads. Payment takes longer. Email lands in spam. A field is left blank. The key expires. The integration responds slowly. The endpoint fails. The user does not know whether the process is complete. The admin receives nothing. The founder believes it works because it worked once.
A system that only works on the happy path has not been reviewed. It has only been demonstrated.
Use this when a feature, file, route, component, provider, integration, or test appears to exist, but you need to confirm whether it participates in the real product.
What actually exists in the code?
Code Reality does not merely deliver a file. It gives you a method for reviewing reality in AI-first software.
AI generates. Nex decides. You are accountable.
