Supplements aren't surprises. They're sequencing failures.

Walk a closed-then-reopened claim backward and you usually find the same story: the supplement was photographed the first time. The evidence was in the upload. What was missing was the connection between an exterior entry point and the interior consequence it guarantees.

Why this keeps happening

Reviews are organized by region of the photo set, not by path of the water. You log the roof, you log the gutters, you log the windows — each as a discrete line item. A flashing gap and a ceiling stain land in different photos, reviewed minutes apart, and never get linked. So the interior work is technically 'discovered later,' even though both halves were always visible.

What changes it

Treat each breach as a hypothesis: if water gets in here, where does it end up? When the report reasons across the whole photo set at once — entry point, travel path, downstream evidence — the supplement becomes a line item on day one instead of a callback on day thirty. That's not better adjusters working harder. It's the documentation reasoning the way the water actually moves.
