First payment hop is not in the app's app-ads.txt
The app's app-ads.txt does not list the first payment node's asi and sid as DIRECT or RESELLER.
What it means
The cache has app-ads.txt for app.bundle, but no DIRECT or RESELLER row matches the first SupplyChain node with hp not equal to 0.
Why it matters
That hop is the seller the developer authorised. If app-ads.txt does not list it, the app's inventory is being sold by someone the developer did not name.
How to fix it
The developer must add a line `<asi>, <sid>, DIRECT` or `RESELLER` to app-ads.txt, or the chain's first payment node must use an asi/sid pair that is already listed.
Example that trips it
{ "app": { "bundle": "com.example.app" }, "source": { "schain": { "nodes": [{ "asi": "ssp.example", "sid": "99", "hp": 1 }] } } }Requires --resolve --cache with app-ads/com.example.app/app-ads.txt that does not list ssp.example / 99.
