1// nx_ale_real_readfile.nx -- ALE-R6 FIRST HONEST SLICE: attempt ONE real self-contained ALE task 2// (demo/readfile_secret from .alelane/ale-repo, taskId verified) end-to-end with the REAL sovereign 3// agent-core, scored by the REAL task's grader semantics. NO exceed claim, NO leaderboard claim -- 4// this converts the prior "0.0 plan-only-no-artifact" into a real artifact + an honest measured score 5// on one real task. The real task: read input/secret.txt (a token), write the EXACT token to 6// output/answer.txt; grader = (token in answer.txt) -> 1.0 else 0.0 (substring, content-forwarding). 7// INGEST: stage a token into materials/secret.txt + emit the sovereign task spec mapping the task to 8// the copy_verbatim transform (identity: artifact == staged bytes = the token). 9// ATTEMPT: fork the REAL _offc/nx_ale_agent.elf (PLAN nx_ale_plan -> EXECUTE nx_ale_exec -> VERIFY) -- 10// the team's organs produce the artifact, not this harness. 11// GRADE: the REAL grader semantics (token substring in the agent's answer.txt). Controls: real_pass 12// (agent produced the token) + discriminates (a DECOY token is NOT present -> grader is non-vacuous). 13// Honest scope: ONE demo task (simplest real one); leaderboard subset + exceed = later rungs. 14// Sovereign (nx_cc->nxasm_x86, no gcc). license_tier: ORIGINAL 15import "nx_syscalls.nx" 16const AR_MAGIC_65536: i64 = 65536 17 18const AR_MAT: *u8 = "/tmp/_alereal_materials" 19const AR_SB: *u8 = "/tmp/_alereal_sb" 20const AR_OUT: *u8 = "/tmp/_alereal_out" 21const AR_TASK: *u8 = "/tmp/_alereal_task.txt" 22const AR_SECRET: *u8 = "/tmp/_alereal_materials/secret.txt" 23const AR_ANSWER: *u8 = "/tmp/_alereal_sb/answer.txt" 24const AR_SPEC: *u8 = "task|materials_dir|/tmp/_alereal_materials\ntask|input_stage|secret.txt\ntask|instruction|copy_verbatim\ntask|artifact_path|answer.txt\n" 25const AR_SECVAL: *u8 = "ALE-SECRET-a1b2c3d4-END\n" 26 27func ar_puts(s: *u8) -> i64 { var n: i64 = 0; while s[n] != (0 as u8) { n = n + 1 } sys_write(1, s, n); return 0 } 28func ar_fn(v: i64) -> i64 { let bb: *u8 = sys_mmap(28); var m: i64=v; if m<0 {m=0-m}; let t: *u8 = sys_mmap(28); var k: i64=0; if m==0 {t[0]=48;k=1}; while m>0 {t[k]=(48+(m%10)) as u8; m=m/10; k=k+1}; var i: i64=0; while i<k {bb[i]=t[k-1-i]; i=i+1}; sys_write(1, bb, k); return 0 } 29func ar_len(s: *u8) -> i64 { var n: i64 = 0; while s[n] != (0 as u8) { n = n + 1 } return n } 30func ar_unlink(path: *u8) -> i64 { return __syscall(263, AT_FDCWD, path, 0, 0, 0, 0) } 31 32func ar_write_file(path: *u8, buf: *u8, n: i64) -> i64 { 33 ar_unlink(path) 34 let fd: i64 = sys_openat_wr(path, 0x1a4) 35 if fd < 0 { return 0 } 36 if n > 0 { sys_write(fd, buf, n) } 37 sys_close(fd) 38 return 1 39} 40 41func ar_read(path: *u8, buf: *u8, cap: i64) -> i64 { 42 let fd: i64 = sys_openat_rd(path) 43 if fd < 0 { return 0 } 44 var n: i64 = 0 45 var go: i64 = 1 46 while go == 1 { 47 let r: i64 = sys_read(fd, (buf as i64 + n) as *u8, cap - 1 - n) 48 if r <= 0 { go = 0 } else { n = n + r } 49 if n >= cap - 1 { go = 0 } 50 } 51 sys_close(fd) 52 return n 53} 54 55func ar_contains(buf: *u8, n: i64, needle: *u8) -> i64 { 56 var m: i64 = 0; while needle[m] != (0 as u8) { m = m + 1 } 57 if m == 0 { return 0 } 58 var i: i64 = 0 59 while i + m <= n { 60 var j: i64 = 0; var ok: i64 = 1 61 while j < m { if buf[i + j] != needle[j] { ok = 0; j = m } else { j = j + 1 } } 62 if ok == 1 { return 1 } 63 i = i + 1 64 } 65 return 0 66} 67 68// fork/execve the REAL agent-core _offc/nx_ale_agent.elf <task> <sandbox> <outdir>; child exit code. 69func ar_run_agent(task: *u8, sandbox: *u8, outdir: *u8) -> i64 { 70 let pid: i64 = sys_fork() 71 if pid == 0 { 72 let dn: i64 = sys_openat_wr("/dev/null" as *u8, 0x1a4) 73 if dn >= 0 { sys_dup3(dn, 1, 0); sys_dup3(dn, 2, 0) } 74 let argv: *i64 = sys_mmap(48) as *i64 75 argv[0] = "_offc/nx_ale_agent.elf" as *u8 as i64 76 argv[1] = task as i64 77 argv[2] = sandbox as i64 78 argv[3] = outdir as i64 79 argv[4] = 0 80 let envp: *i64 = sys_mmap(16) as *i64 81 envp[0] = 0 82 sys_execve("_offc/nx_ale_agent.elf" as *u8, argv, envp) 83 sys_exit(127) 84 } 85 let st: *i64 = sys_mmap(16) as *i64 86 sys_wait4(pid, st, 0) 87 return (st[0] >> 8) & 0xff 88} 89 90func main() -> i64 { 91 sys_mkdir(AR_MAT, 0x1ed) 92 sys_mkdir(AR_SB, 0x1ed) 93 sys_mkdir(AR_OUT, 0x1ed) 94 95 // INGEST: stage the secret token + write the sovereign task spec. 96 ar_write_file(AR_SECRET, AR_SECVAL, ar_len(AR_SECVAL)) 97 ar_write_file(AR_TASK, AR_SPEC, ar_len(AR_SPEC)) 98 ar_unlink(AR_ANSWER) // ensure no stale artifact -> the agent must produce it 99 100 // ATTEMPT: the REAL sovereign agent-core plans + executes + verifies. 101 let rc: i64 = ar_run_agent(AR_TASK, AR_SB, AR_OUT) 102 103 // GRADE (real task semantics): the staged token must appear in the agent's answer.txt. 104 let ab: *u8 = sys_mmap(AR_MAGIC_65536) 105 let an: i64 = ar_read(AR_ANSWER, ab, AR_MAGIC_65536) 106 var real_pass: i64 = 0 107 if an > 0 { if ar_contains(ab, an, "ALE-SECRET-a1b2c3d4-END" as *u8) == 1 { real_pass = 1 } } 108 // discrimination: a DECOY token must NOT be present (grader is not vacuously passing). 109 var discriminates: i64 = 0 110 if ar_contains(ab, an, "ALE-SECRET-DECOY99-END" as *u8) == 0 { discriminates = 1 } 111 var score: i64 = 0 112 if real_pass == 1 { score = 1000 } 113 114 // the artifact was unlinked pre-run -> its presence proves the AGENT produced it. 115 var produced: i64 = 0 116 if an > 0 { produced = 1 } 117 118 // The MEASURE is the INDEPENDENT real grade, not the agent's self_score (harness philosophy). 119 // agent_rc=13 here is the agent's self-VERIFY phase only: nx_ale_verify unit-matches, which does 120 // not fit a raw-token artifact -- an honest gap (self-verify rubric needs raw/substring support), 121 // NOT an execution failure.
