+# Authorized post-snapshot baseline cleanup
+
+The 38-unit archive and its original root index were verified before deletion. The immutable root index and its initial cleanup status describe that capture time; this appended record describes the later human-authorized cleanup. They are not overwritten.
+
+1,121,552 archived files/symlinks were removed; original file data totaled 248,370,031,738 bytes. The complete per-unit record is [confirmed_baseline_cleanup.json](confirmed_baseline_cleanup.json).
+
+Shared dependencies, upload/control support, excluded benchmark geometry, private VCS metadata and credential-bearing files were not removed. Original Windows numeric tables remain unchanged.
+
+Restore removed material from each listed unit archive manifest and all of its tar shards, checking LFS SHA-256 and using the large-file reassembly helper where required. The updated cleanup implementation/tests accompany this post-snapshot record. No method or reported numeric value changed.
