Nobody has read your AI-generated codebase
It runs, it demos, and no human has traced a request through it end to end. Here is what that costs, and the four things worth checking first.

What the work taught us.
Written from systems that shipped. Each piece names a problem, explains the mechanism underneath it, and says what it costs to get wrong.

Someone still has to answer for it
Generation gets cheaper every year. Being the party who answers when a regulator asks who approved the data model does not, and that gap is widening.
Healthcare
What a HIPAA reviewer asks for first
Reviews do not start with encryption. They start with a question most systems cannot answer, and the order tells you what to build before the letter arrives.
AI Systems
Engineer the boundary, generate the implementation
The useful split is not humans versus agents. It is that the decisions live upstream and the code lives downstream, and only one of those can be handed over.
AI Systems
Retrieval that cannot cross a tenant boundary
A similarity search has no concept of a customer. Where you put the filter decides whether that is a design detail or a disclosure, and both failures look like a ranking bug.

Why a lab report is harder than a PDF
A result means nothing without the range it was read against, and that range moves. Which makes the report a snapshot, not a view over live data.
Healthcare
One appointment, four funding schemes
The patient is shown a single price before any payer has answered. Everything difficult about health booking follows from that one sentence.
Industrial
A diamond is not a SKU
Every stone is unique across nine graded attributes, so inventory holds individuals rather than counts and search runs against a description rather than an identifier.
Professional Services
The invoice total is not what arrives
Where tax is withheld at source, the payer decides what lands in your account. Three numbers per invoice, and two of them are outside your control.
Healthcare
Treatment sold as a package of sessions
Money taken up front against care not yet given. The balance owed is denominated in sessions, not currency, and the two have to agree.
Fintech
A year of trading into a tax position you can defend
Broker statements disagree with each other and with the return. Producing the number is the easy half; being able to show how it was derived is the product.
Marketplaces
Disputes are the product
When something comes back damaged, the platform arbitrates between two parties it does not employ. Whether it can is decided long before the dispute is raised.
Marketplaces
The lead is the product
In a marketplace that sells intentions to buy, moderation sits between two impatient sides and the platform is paid on volume while one side needs quality.
E-commerce
Paying out to vendors who are owed different amounts
One customer order becomes many obligations in several currencies. The transaction is the easy half; what the ledger says a week later is the product.
Consumer Platforms
Recommendations the merchants cannot buy
One side pays for visibility, the other needs an honest answer. Once ranking is purchasable the product stops working for both, in that order.
Recognise the problem?
If one of these describes where you are, the first conversation is usually short and tells you whether we are useful.
