What’s the brass check next to my receipt?
It means the receipt is sealed: we recorded a fingerprint of the file when it was stored, so any later change to it can be detected. A greyed-out mark means the record has no fingerprint on file.
This is separate from the green check in the Status column, which tracks whether you have reviewed the details we extracted. One is about the file, the other is about the data.
For the full explanation, see What “Sealed & Verified” means.
