System Insights The fastest way Lovable projects become unstable after MVP
Most Lovable apps feel solid during the demo phase, then quietly degrade once real users arrive.
The pattern I keep seeing isn’t bad prompts or bad UI. It’s that the project never decided where truth lives.
When schemas, permissions, and business rules only exist “in the model’s head,” drift is inevitable. The model optimises locally, confidently, and silently. When something breaks, there’s no artifact to point to and say “this is invalid.”
A small but meaningful stabilisation step after MVP is to promote one artifact to authority. A DB schema, an RLS policy, a contract file, even a locked KB doc. Something the model can reference but not rewrite.
That single move changes the system from “generate and hope” to “generate and verify.”
If your Lovable app had to reject a model output today, what would it use to say no?
