 Last generated patch:
 
-- `0477 build: expose nwssl error helpers for nwwebui`
+- `0478 build: expose core include paths to nwfs imports`
 
 Purpose of that patch:
 
-- Keep `nwwebui` on the shared `nwssl`/MatrixSSL compatibility path instead of
-  adding a direct OpenSSL dependency for TLS error handling.
-- Export the small OpenSSL-shaped `ERR_get_error()` and `ERR_error_string_n()`
-  surface that the SMArT-derived `nwwebui` logging path uses.
-- Make MatrixSSL compatibility errors printable through the existing
-  OpenSSL-shaped error API, so `nwwebui` can compile against `mars_nwe::ssl` and
-  log TLS failures through `nwlog`.
+- Make `nwfs` consume the already-imported `libnwcore` header surface through
+  normal target usage requirements instead of copying or symlinking core
+  headers under `include/nwfs`.
+- Add the generated build include directory and `include/core` to the `nwfs`
+  public build interface so adapted NSS namespace files can include core helper
+  headers directly while still linking against `mars_nwe::core`.
+- Keep the NSS-specific SDK/include directories scoped to the namespace import
+  path that still needs them; do not add another duplicate header staging area.
