+"""The one-line verdict test for this artifact.
+
+Runs the archive's own independent checker against the COMMITTED bytes in the
+troupe repo. That checker:
+  * re-hashes the persisted API response and both abs pages against the manifest,
+  * re-parses the XML and re-derives every invariant the report claims,
+  * re-queries the live arXiv API to prove the 19-entry slice is complete,
+  * cross-checks ARCHIVE.md against the evidence,
+  * exits nonzero on any mismatch.
+
+This is a real test: it fails if any byte of evidence is altered, if the report
+drifts from the evidence, or if the slice is no longer complete.
