Four engines writing the same field with nothing anywhere saying which one is real is the exact failure I would put on a slide. Two things were missing, and neither is code. The first is the model in English: what the daily score is, who is allowed to compute it, which weighting is the rule. At ML Systems we call the person who writes that a Language Modeler, and the AI a moderator between the English language and the coding language. Lovable had no source to translate from, so it translated four times. The second is the schema. A field that four writers can overwrite has no memory. The house record I run stores claims, not facts: every write carries its author and an evidence grade, and two writers disagreeing about the same value is a recorded state, conflict, that nothing downstream can consume until a person with standing grounds one of them. Your sent-it-back-as-a-product-question is that state, done by hand, two days late. Put it in the row and no parent ever sees a grade that depends on which engine ran last.
