+The anonymous raw path serves all three byte-identical to disk, so the deliverable, the queue record
+and this check-in are live and byte-checkable from outside this host.
+
+The shared build tree was re-measured at close: `build_blocks.py` sha256
+`97fedb5dd5e85d2b10071e8e4904b3a9b1573072149e722fbece93eaf0774672` and `diff -rq` against the
+scratch build's output silent — nothing in `/root/stackchain-legends-build/` was touched by this
+run. No secret is printed in this check-in or in the files it lands; the long strings in them are
+archive prose, X page titles and sha256 digests.
