1// nx_forge_bestof.nx -- BEST-OF-N sampling on fbench T1 with the 1.5B coder + mini-pack (quality lever #2, 2// 2026-07-15). Greedy 1.5B+minipack COMPILES+RUNS but misses bytes (semantic near-miss); temperature sampling 3// explores variants and the byte-exact judge (fg_run) picks any GREEN -- soundness by judging, diversity by 4// sampling. PREFIX-CACHE makes this affordable: sample 1 prefills the ~1350-tok prompt ONCE (snapshot), every 5// further sample re-prefills only the clamped last token (identical prompt) + generates. Early-exit on GREEN. 6// Appends an organ-authored living record (localpass=) to the codegen bench ledger. license_tier: ORIGINAL 7// expect_exit: 0 (measurement organ; the count is the deliverable) 8import "nx_nofloat_serve_core.nx" 9import "nx_forge.nx" 10const K_MAGIC_32768: i64 = 32768 11const K_MAGIC_16384: i64 = 16384 12const K_MAGIC_30000: i64 = 30000 13const K_MAGIC_65536: i64 = 65536 14 15// read the mini-pack file into buf; ret len (or <0) 16func bo_read_pack(buf: *u8, cap: i64) -> i64 { 17 let fd: i64 = sys_openat_rd("knowledge/forge/nishilang_pack_mini_v1.txt" as *u8) 18 if fd < 0 { return 0 - 1 } 19 var o: i64 = 0 20 var reading: i64 = 1 21 while reading == 1 { 22 let q: *u8 = buf + o 23 let rem: i64 = cap - 1 - o 24 if rem <= 0 { reading = 0 } else { 25 let r: i64 = sys_read(fd, q, rem) 26 if r <= 0 { reading = 0 } else { o = o + r } 27 } 28 } 29 sys_close(fd) 30 buf[o] = 0 as u8 31 if o < 1000 { return 0 - 1 } 32 return o 33} 34 35func bo_cat(buf: *u8, o: i64, s: *u8) -> i64 { 36 var i: i64 = 0 37 var oo: i64 = o 38 while s[i] != (0 as u8) { buf[oo] = s[i]; oo = oo + 1; i = i + 1 } 39 buf[oo] = 0 as u8 40 return oo 41} 42 43// strip a leading ```fence + trailing ``` (copy of lg_strip semantics, self-contained) 44func bo_strip(src: *u8, n: i64, out: *u8) -> i64 { 45 var f0: i64 = 0 - 1 46 var i: i64 = 0 47 let stop: i64 = n - 3 48 while i <= stop { 49 let c0: i64 = src[i] as i64 50 let c1: i64 = src[i + 1] as i64 51 let c2: i64 = src[i + 2] as i64 52 if c0 == 96 && c1 == 96 && c2 == 96 { f0 = i; i = stop + 1 } 53 if f0 < 0 { i = i + 1 } 54 } 55 if f0 < 0 { 56 var k: i64 = 0 57 while k < n { out[k] = src[k]; k = k + 1 } 58 out[n] = 0 as u8 59 return n 60 } 61 var cs: i64 = f0 + 3 62 var sc: i64 = 1 63 while sc == 1 { 64 if cs >= n { sc = 0 } 65 if sc == 1 { 66 let c: i64 = src[cs] as i64 67 cs = cs + 1 68 if c == 10 { sc = 0 } 69 } 70 } 71 var f1: i64 = n 72 var j: i64 = cs 73 let stop2: i64 = n - 3 74 while j <= stop2 { 75 let d0: i64 = src[j] as i64 76 let d1: i64 = src[j + 1] as i64 77 let d2: i64 = src[j + 2] as i64 78 if d0 == 96 && d1 == 96 && d2 == 96 { f1 = j; j = stop2 + 1 } 79 if f1 == n { j = j + 1 } 80 } 81 var o: i64 = 0 82 var p: i64 = cs 83 while p < f1 { out[o] = src[p]; o = o + 1; p = p + 1 } 84 out[o] = 0 as u8 85 return o 86} 87 88// write buf[0,n) to path (0644) 89func bo_write(path: *u8, buf: *u8, n: i64) -> i64 { 90 let fd: i64 = sys_openat_wr(path, 420) 91 if fd < 0 { return 0 - 1 } 92 var off: i64 = 0 93 while off < n { 94 let q: *u8 = buf + off 95 let w: i64 = sys_write(fd, q, n - off) 96 if w <= 0 { off = n } 97 if w > 0 { off = off + w } 98 } 99 sys_close(fd) 100 return n 101} 102 103// v2 (2026-07-15): ONE SAMPLE PER PROCESS (argv[1]=sample index 0..3) at i8 fast mode -- fits reliable 104// foreground tool calls (the WSL background lifecycle SIGTERMs long detached runs; root-caused exit-15). 105// Sample 0 prefills + SAVES the snapshot to disk; samples 1..3 LOAD it (fresh process, no re-prefill). 106// Judge-side soundness: mode cannot fake a green (fg_run compiles+runs+byte-compares the OUTPUT). 107func main(argc: i64, argv: *i64) -> i64 { 108 var green: i64 = 0 109 var compiled: i64 = 0 110 var s: i64 = 0 111 var firstgreen: i64 = 0 - 1 112 let N: i64 = 1 113 114 if argc >= 2 { 115 let a1: i64 = argv[1] 116 let arg1: *u8 = a1 as *u8 117 let d: i64 = arg1[0] as i64 118 if d >= 48 { if d <= 57 { s = d - 48 } } 119 } 120 std_puts("BEST-OF-N v2 (per-process sample, i8): sample=" as *u8) 121 std_pdec(s) 122 std_puts("\n" as *u8) 123 124 // prompt = mini-pack + T1 task + contract 125 let pbuf: *u8 = sys_mmap(K_MAGIC_32768) as *u8 126 var plen: i64 = bo_read_pack(pbuf, K_MAGIC_32768) 127 if plen <= 0 { 128 std_putln("PACK READ FAIL" as *u8) 129 sys_exit(1) 130 return 1 131 } 132 plen = bo_cat(pbuf, plen, "\nTASK: print EXACTLY this line then exit 0:\nFBENCH-T1 fib10=55 sum100=5050\n(fib(10), fib(1)=fib(2)=1; sum 1..100.)\n" as *u8) 133 plen = bo_cat(pbuf, plen, "Write a COMPLETE NishiLang program.
