1// nx_audio_render_gate.nx -- gate for the zero-JS audiobook player (SC33-37 rung 1): 2// nx_m4b_fixture -> nx_m4b_book -> reader/<slug>/audio.json -> nx_audio_render -> player.html. 3// Asserts the page is a SOVEREIGN zero-JS native player: 0 <script>, a native <audio controls src=track>, the 4// liberated metadata (title/narrator), and the daemon-API affordances (speed-variant / sleep-timer / bookmark 5// controls that target the Nishi audio daemon -- the "Nishi-code APIs" that do the player work server-side, NOT in 6// the browser). GREEN = SC33 basic playback works zero-JS + the SC33-37 daemon surface is laid out. tier: ORIGINAL 7import "nx_syscalls.nx" 8 9func gp(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(1,s,n); return 0 } 10func gnum(v0: i64) -> i64 { var v: i64=v0; if v<0 { sys_write(1,"-" as *u8,1); v=0-v } let b: *u8=sys_mmap(24); var k: i64=0; if v==0 {b[0]=48 as u8;k=1} while v>0 {b[k]=(48+(v%10)) as u8; v=v/10; k=k+1} let o: *u8=sys_mmap(24); var j: i64=0; while j<k {o[j]=b[k-1-j];j=j+1} sys_write(1,o,k); return 0 } 11func ghas(hay: *u8, hl: i64, needle: *u8) -> i64 { 12 var nl: i64=0; while needle[nl]!=(0 as u8){nl=nl+1} 13 if nl == 0 { return 0 } 14 var i: i64 = 0 15 while i + nl <= hl { var k: i64=0; var hit: i64=1; while k<nl { if hay[i+k]!=needle[k]{hit=0;k=nl}else{k=k+1} } if hit==1 {return 1} i=i+1 } 16 return 0 17} 18func rd(path: *u8, lenp: *i64) -> *u8 { lenp[0]=0; return sys_read_file(path, lenp) } 19func spawn(path: *u8, a0: *u8, redir: *u8) -> i64 { 20 let pid: i64 = sys_fork() 21 if pid == 0 { 22 let fd: i64 = sys_openat_wr(redir, 420) 23 if fd >= 0 { sys_dup3(fd, 1, 0); sys_dup3(fd, 2, 0) } 24 let argv: *i64 = sys_mmap(64) as *i64 25 argv[0] = path as i64 26 if (a0 as i64) != 0 { argv[1] = a0 as i64; argv[2] = 0 } else { argv[1] = 0 } 27 let envp: *i64 = sys_mmap(16) as *i64 28 envp[0] = "PATH=/usr/bin:/bin\x00" as *u8 as i64; envp[1] = 0 29 sys_execve(path, argv, envp) 30 sys_exit(127) 31 } 32 let st: *i64 = sys_mmap(16) as *i64 33 sys_wait4(pid, st, 0) 34 return (st[0] >> 8) & 0xff 35} 36 37func main() -> i64 { 38 gp("=== nx_audio_render_gate: zero-JS audiobook player page (SC33-37 rung 1, native <audio> + daemon API) ===\n" as *u8) 39 let RUNNER: *u8 = "_offc/nx_sov_build_run.elf\x00" as *u8 40 let SC: *u8 = "knowledge/status/audio_render_gate_scratch.log\x00" as *u8 41 42 spawn(RUNNER, "nx_m4b_fixture\x00" as *u8, SC) 43 spawn(RUNNER, "nx_m4b_book\x00" as *u8, SC) 44 let rc: i64 = spawn(RUNNER, "nx_audio_render\x00" as *u8, SC) 45 46 let lh: *i64 = sys_mmap(8) as *i64; let h: *u8 = rd("knowledge/staging/media/reader/nishi_m4b_fixture/player.html\x00" as *u8, lh); let hn: i64 = lh[0] 47 48 gp(" rc_render=" as *u8); gnum(rc); gp(" player.html=" as *u8); gnum(hn); gp("B\n" as *u8) 49 50 var pass: i64 = 0; var fail: i64 = 0 51 if rc == 0 { pass=pass+1 } else { fail=fail+1; gp(" FAIL render-nonzero\n" as *u8) } 52 if (h as i64)==0 { gp("AUDIO-RENDER-GATE pass=" as *u8); gnum(pass); gp(" fail=1 verdict=RED no-player.html\n" as *u8); sys_exit(1); return 1 } 53 // SOVEREIGN zero-JS 54 if ghas(h, hn, "<script" as *u8)==0 { pass=pass+1 } else { fail=fail+1; gp(" FAIL has-script\n" as *u8) } 55 // native player + the liberated track 56 if ghas(h, hn, "<audio controls" as *u8)==1 { pass=pass+1 } else { fail=fail+1; gp(" FAIL no-audio-element\n" as *u8) } 57 if ghas(h, hn, "src=\"track0.m4b\"" as *u8)==1 { pass=pass+1 } else { fail=fail+1; gp(" FAIL no-track-src\n" as *u8) } 58 // metadata 59 if ghas(h, hn, "The Hobbit (Nishi M4B Fixture)" as *u8)==1 { pass=pass+1 } else { fail=fail+1; gp(" FAIL no-title\n" as *u8) } 60 if ghas(h, hn, "J.R.R.
