nx_tool_census_run_test.nx

nx_tool_census_run_test.nx -- end-to-end bits-up audit binary. Composes nx_dir_list (syscall walk) + sys_openat_rd / sys_read / sys_close (per-file I/O) + nx_tool_census_classify (sealed-enum classifier) + nx_tool_census_accumulate (counts) -- all in bits-up NishiLang. No bash / grep / xargs / awk in the LOGIC or I/O paths. Smoke harness creates /tmp/nx_census_fixture/ with 4 synthetic files: nx_alpha.nx header has 'AUTO-GENERATED' -> AUTO_GENERATED nx_bravo.nx header has 'Composes: nx_x' -> HAND_WRITTEN_DECLARED nx_charlie.nx header is plain -> HAND_WRITTEN_UNDECLARED nx_delta_test.nx any content (suffix wins) -> TEST This binary walks that dir + verifies counts match. Exit 0 = PASS; non-zero codes identify which assertion failed. Substrate's first end-to-end bits-up audit executable.
