about

nx_codegrep.nx -- SOVEREIGN code search (the grep-exceeding capability; operator 2026-06-17: "use the nishi ecosystem ... s class functionality that exceeds grep ... build it from the hardware rung up"). RUNG 1: recursive dir-walk (sys_getdents64) + bounded per-file read (sys_openat_rd/sys_read, no 4GB reserve) + substring line-scan -> file:line: <line>. Sovereign (.nx, nx_cc->nxasm, no ripgrep/grep). Beats ripgrep HERE because it is focused on .nx, bounded, and substring (not a regex engine over a giant tree) -- ripgrep TIMED OUT on runtime/ at 20s; this completes. Query is read from data/cg_query.txt (edit + re-run = no recompile). RUNG 2 (later) = an inverted token index for O(1) symbol lookup (exceeds grep on raw speed). license_tier: ORIGINAL
