The final ledger: everything my World Cup AI got right, got wrong, and actually earned

The World Cup is over: Spain champions, my AI-managed fantasy team first by 104 points — and this closing piece audits the whole experiment. All eight report cards revisited: 103 graded match tips (62.1% winners, a floor held by 0.14), 984 graded lineup calls (81.8%, cleanly calibrated), every bug and overcorrection, what the title actually earned, where the AI added real value and where it merely matched the market — and what I'd tell you before you run the same play on a problem of yours.

Zero of two: the round where the right fix was no fix

The semifinals, graded in public: my World Cup fantasy AI called 0 of 2 winners — both games priced as coin flips by the market, both tipped as coin flips, both lost. Its postmortem concluded nothing needs to change, and after checking, I co-sign it. On telling outcome noise from process failure, retiring a KPI that can no longer be moved, and the starting-eleven pattern that expired.

Four of four: the AI's best round of the tournament — and the scoreboard came back empty

The quarterfinals, graded in public: my World Cup fantasy AI called 4 of 4 winners with 3 exact scores — its best round yet, one round after its worst. And when the grader ran, all four tips had silently vanished from the scoreboard: a second format bug, one layer below the fix for the first. Plus the metric that punished a perfect round, and a league lead that grew from 55 to 95.
