Check before you publish.
A fix can be proven. Luminol replays the relevant journey on your Google Tag Manager draft, before it goes live.
The draft, tested like production
With your agreement, Luminol prepares the fix in a GTM workspace of its own, loads that draft in its browser and replays the refusal or the withdrawal.
It never publishes: you publish, once the fix is proven.
A fix measured, not declared
At the next scan, a fix only counts as done if the relevant moment was actually replayed and the leak is gone. Your home page shows the progress, scan after scan.
