1// nx_meet_signals.nx -- P5: the anti-fake signal table as EDITABLE DATA (LIBRARY, no main). A data-driven twin of 2// the hardcoded R6 scorer (nx_meet_trust), so an operator can tune detection -- add a buzzword, change a weight -- 3// by editing a `sig|<kind>|<dir>|<weight>|<phrase>` file, no recompile. kind=resume|posting, dir=fake(subtract)| 4// good(add). The numeric digit-bonus stays structural (a char-class, not a phrase). The gate PROVES this reproduces 5// the hardcoded reference on the R6 fixtures (so nothing regresses) AND that editing the table changes detection. 6// license_tier: ORIGINAL 7import "nx_syscalls.nx" 8import "nx_meet_lib.nx" 9import "nx_meet_trust.nx" 10const K_MAGIC_1024: i64 = 1024 11 12func sig_streq(a: *u8, b: *u8) -> i64 { 13 let al: i64 = mlen(a); let bl: i64 = mlen(b) 14 if al != bl { return 0 } 15 var i: i64 = 0 16 while i < al { if a[i] != b[i] { return 0 } i = i + 1 } 17 return 1 18} 19func sig_atoi(s: *u8) -> i64 { 20 var v: i64 = 0; var i: i64 = 0 21 while s[i] != (0 as u8) { let c: i64 = s[i] as i64; if c >= 48 { if c <= 57 { v = v * 10 + (c - 48) } } i = i + 1 } 22 return v 23} 24 25// the default signal table -- BYTE-FOR-BYTE the markers + weights hardcoded in nx_meet_trust (so the data-driven 26// scorer reproduces it exactly).
