 ## Current patch handoff block
 
-Last completed work block: **namespace userspace uniqueness boundary**
+Last completed work block: **MD consistency and doc consolidation pass**
 
-The latest design work clarifies how imported NSS namespace code should be used
-for future Mars/NWFS integration.  `libnwnss` remains the NSS namespace provider
-using the real `src/nwnss/comn/namespace` implementations.  A later `nwfs`
-wrapper will translate Mars volume options, host paths, search handles and
-compatibility policy before calling into `libnwnss`; the current half-finished
-`nwfs` namespace staging remains ignored until that cleanup phase.
+All repository markdown files were audited for stale paths and cross-file
+inconsistencies.  Outdated references to `include/nwfs/nss/`, `src/nwfs/nss/`,
+`include/core/`, `src/core/` and `wolfssl` were corrected.  Fifteen smaller
+doc files were consolidated into five topic-focused files under `doc/`.  The
+`nwfs.nss.namespace-import-layout` test was updated from the merged-away
+`doc/NSS_NAMESPACE_AUDIT.md` to the new `doc/NSS_IMPORT_NOTES.md`.
 
-Most namespace operations are pure provider helpers and can be called through the
-real NSS families directly: compare, wildcard match/replace, ASCII/Unicode
-conversion, legal-name checks and component scanning for DOS, LONG/OS2,
-UNIX/NFS, MAC, DATASTREAM and EA.  `*_generateUniqueName()` is the exception: it
-requires directory uniqueness/collision lookup.  HostFS, OtherFS, sidecar or
-Mars directory enumeration for that path belongs in a parallel
-`nameSpaceUserspace.c` / `nameSpaceUserspace.h` boundary, not inline in
-`dosNSpace.c`, `longNSpace.c`, `unixNSpace.c`, `macNSpace.c` or `nameSpace.c`.
+Ownership boundaries for service processes, quota/salvage, namespace uniqueness
+and the libnwnss/nwfs backend split were documented as durable design decisions
+across `REDESIGN.md`, `AI.md`, and `CLAUDE.md`.
+
+Test suite is 62/62 green.  Build directory is
+`/home/mario/mars/mars-nwe-build` (out-of-tree).
