nx_doc_func_scan.nx

nx_doc_func_scan.nx -- bits-up function-pattern extraction. Substrate-canonical building block for replacing bash + grep + awk in audit primitives. Extracts `func NAME(` patterns from NishiLang source content, returns iterator results compatible with nx_doc_extract_link_target's pattern. Per [[feedback-bits-up-shell-replace-linux-brother-tools]]: substrate's audit infrastructure stops depending on Linux-brother tools for its own self-audit. bench/nx_audit_within_file_func_ duplicates.sh (bash) is INTERIM; bits-up nx_audit_func_duplicates composes THIS primitive. **Quadrant:** REFERENCE (Diátaxis) **Topic Type:** REFERENCE (DITA) **Status:** DRAFT (first stone; bits-up substitute for bash audit detector) **Trust State:** WRITTEN_UNTESTED **Competitive State:** UNCLASSIFIED (no benchmark vs grep+awk substrate-internally yet)
