+## Host-side NSS/OES metadata readback
+
+After running trustee, rights, flag, creator, or quota-related DOS tests against a
+MARS-NWE `SYS:` tree, collect the canonical NSS/OES xattrs from the host with:
+
+```sh
+sh dosutils/test/cmnwmeta.sh /path/to/SYS /path/to/nwfs_xattr_dump > meta.log
+```
+
+The collector decodes `netware.metadata`, `netware.quota`, and
+`netware.userquota` from the files and directories changed by the DOS tests.
+This is the expected verification layer for the NSS migration: DOS tools or
+NCPFS perform the mutation, and `nwfs_xattr_dump` proves that the resulting
+state landed in the OES-compatible `netware.*` metadata rather than only in the
+legacy mars-nwe side stores.
+
 ## Packaging
 
 Most test directories have a matching `*ZIP.BAT` that packages the result tree
