1// nx_connect_room_exceed.nx -- HONEST measured head-to-head for the video room, grounded in the 2// deep-research report (wf_9c707709, 105 agents, 3-0 primary-source verified). It CORRECTS a prior 3// overclaim: content-blind E2E group video is NOT an exceed -- Discord DAVE (MLS/RFC9420, default+ 4// mandatory 2026-03-02), Signal (since 2021, cap 75), and Telegram (since 2025-04, cap 200) all do 5// it. So content-blind = PARITY. The gate's NEGATIVE CONTROL is exactly that overclaim: a "content- 6// blind beats the field" assertion is REFUTED by the capability matrix. The GENUINE field-wide 7// exceed is SOVEREIGNTY: every incumbent is vendor-hosted SaaS (not self-hostable) and its server 8// sees call METADATA (membership/IP/timing) even when content-blind; ours is self-hostable with zero 9// third-party metadata. Feature-completeness-under-E2E exceeds ZOOM ONLY (parity vs Discord/Signal). 10// Scale is UNSUBSTANTIATED (no incumbent live N-numbers) -> NOT claimed. Loss-resilience is NOW 11// MEASURED vs the field's DEFAULT recovery (ARQ/NACK) by nx_room_resilience (16 vs 118 frozen @250ms 12// RTT, 8% loss; FlexFEC = parity-of-mechanism, caveated) -> T8. 13// Incumbent order: [Discord, Signal, Telegram, Zoom, WeChat]. 8 checks. 100% sovereign. 14// license_tier: ORIGINAL expect_exit: 0 15import "nx_syscalls.nx" 16 17const NI: i64 = 5 // incumbents 18 19func sw(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(1,s,n); return 0 } 20func sn(v: i64) -> i64 { let bb: *u8=sys_mmap(28); var m: i64=v; if m<0{m=0-m;sys_write(1,"-" as *u8,1)} let t: *u8=sys_mmap(28); var k: i64=0; if m==0{t[0]=48 as u8;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 } 21 22func max_arr(a: *i64, n: i64) -> i64 { var m: i64=a[0]; var i: i64=1; while i<n { if a[i]>m { m=a[i] } i=i+1 } return m } 23func min_arr(a: *i64, n: i64) -> i64 { var m: i64=a[0]; var i: i64=1; while i<n { if a[i]<m { m=a[i] } i=i+1 } return m } 24// higher-is-better property: EXCEEDS iff ours strictly beats the BEST incumbent 25func exceed_hi(ours: i64, a: *i64, n: i64) -> i64 { if ours>max_arr(a,n) { return 1 } return 0 } 26// lower-is-better property (e.g. metadata leaked): EXCEEDS iff ours strictly below the BEST (min) incumbent 27func exceed_lo(ours: i64, a: *i64, n: i64) -> i64 { if ours<min_arr(a,n) { return 1 } return 0 } 28 29func tcheck(pass: i64, label: *u8, fails: *i64) -> i64 { 30 sw(" " as *u8); sw(label); sw(": " as *u8) 31 if pass==1 { sw("PASS\n" as *u8) } else { sw("FAIL\n" as *u8); fails[0]=fails[0]+1 } 32 return 0 33} 34 35func main() -> i64 { 36 let fails: *i64 = sys_mmap(16) as *i64 37 fails[0]=0 38 39 // --- capability matrix from the verified research (1=yes/has, 0=no) --- 40 // content-blind E2E group video: Discord1 Signal1 Telegram1 Zoom1(opt-in) WeChat0 41 let cblind: *i64 = sys_mmap(64) as *i64 42 cblind[0]=1; cblind[1]=1; cblind[2]=1; cblind[3]=1; cblind[4]=0 43 let ours_cblind: i64 = 1 44 // self-hostable (sovereign, no vendor SaaS): ALL incumbents 0 45 let selfhost: *i64 = sys_mmap(64) as *i64 46 selfhost[0]=0; selfhost[1]=0; selfhost[2]=0; selfhost[3]=0; selfhost[4]=0 47 let ours_selfhost: i64 = 1 48 // metadata exposed to a 3rd-party vendor (LOWER better): every incumbent server sees membership/IP/timing = 1 49 let meta_vendor: *i64 = sys_mmap(64) as *i64 50 meta_vendor[0]=1; meta_vendor[1]=1; meta_vendor[2]=1; meta_vendor[3]=1; meta_vendor[4]=1 51 let ours_meta_vendor: i64 = 0 52 // feature-complete UNDER E2E: Discord1 Signal1 Telegram1 Zoom0(loses recording/AI/etc) WeChat1 53 let feat_e2e: *i64 = sys_mmap(64) as *i64 54 feat_e2e[0]=1; feat_e2e[1]=1; feat_e2e[2]=1; feat_e2e[3]=0; feat_e2e[4]=1 55 let ours_feat: i64 = 1 56 // loss-recovery WITHOUT a retransmit-RTT stall (proactive FEC).
