Attribution breaks when one dashboard becomes the truth. A campaign can claim conversions, GA4 can miss revenue, and the backend can still prove what actually sold. jujugrowth keeps those three numbers separate so the gap is visible before it drives a bad budget decision.
Read-only OAuth. Official API only, no card, no trial clock, no spend changes. You approve every change.
The point is not to declare one attribution model perfect. The point is to expose the disagreement. If the platform number is high and backend truth is low, spend may be chasing a proxy. If backend truth exists and GA4 shows zero, tracking is broken. If all three agree, you finally have a number worth acting on.
Ad platforms credit conversions using their own pixels, windows and modeling. GA4 measures site behavior, and your store or backend records the sale that actually happened. jujugrowth keeps all three numbers side by side for the same dates so you can see whether the platform over-claimed, analytics missed revenue, or tracking broke.
Dogfood example: jujugrowth found $69 of real subscription and credit revenue over five days that GA4 reported as $0. The backend proved the money existed. GA4 proved the purchase event was not reaching analytics. The fix was a tracking repair, not a budget guess.
It starts read-only. It can see the numbers, but it cannot spend or change your accounts by default. You keep control while the system keeps the truth visible.
