+Latest endpoint audit checkpoint from patch 0242:
+
+- Continuing the corrected NDK-first pass, SDK `0x2222/23` / wire `0x17`
+  File Server Environment now records the NetWare-2.x server statistics block
+  `23/212` through `23/217` as disabled source stubs in `src/nwbind.c`: Get
+  File System Statistics, Get Transaction Tracking Statistics, Read Disk Cache
+  Statistics, Get Drive Mapping Table, Read Physical Disk Statistics, and Get
+  Disk Channel Statistics.
+- These selectors are reached through the normal `nwconn.c` File Server
+  Environment forward path into `nwbind.c`.  There was no active implementation
+  for the wire `0xd4`..`0xd9` subfunction slots before this documentation
+  marker.
+- Do not synthesize fake NetWare FAT/cache, TTS, SFT mirror, physical-disk, or
+  disk-channel counter blocks.  Future ownership belongs to a servermgmt/
+  statistics provider backed by real filesystem, volume, and backend state.
+- The next NDK-first `23/xx` statistics/monitoring audit block should continue
+  with the nearby open-file/lock/semaphore/usage selectors such as `23/219`
+  through `23/242`, keeping small reviewable sub-blocks.
+
+Next patch number should be `0243`.

 - Continue endpoint audit by selecting the next documented 1.x/2.x/3.x gap or

+### File Server Environment 23/212..217 NDK-first statistics stubs
+
+Current status:
+
+- The NDK-first pass over SDK `0x2222/23` found the in-scope NetWare-2.x server
+  statistics selector run `23/212` through `23/217`: Get File System
+  Statistics, Get Transaction Tracking Statistics, Read Disk Cache Statistics,
+  Get Drive Mapping Table, Read Physical Disk Statistics, and Get Disk Channel
+  Statistics.
+- Patch `0242` records these as disabled `#if 0` source stubs in `src/nwbind.c`
+  at wire subfunctions `0xd4` through `0xd9`.  They remain disabled because the
+  current backend does not model NetWare FAT/cache, TTS, SFT mirror, physical
+  disk, or disk-channel tables.
+- Future implementation belongs to a servermgmt/statistics provider using real
+  filesystem, volume, and backend state.  Do not invent fake counter blocks just
+  to satisfy legacy monitoring callers.
+
+Follow-up:
+
+- Continue the NDK-first File Server Environment monitoring/statistics audit with
+  the nearby open-file, lock, semaphore, usage, and volume-information selectors
+  such as `23/219` through `23/242`, split into small reviewable blocks.
