1// nx_research_cleanup.nx -- SOVEREIGN deletion of the 7 copy-paste nx_*_research_fetch organs, now SUPERSEDED by 2// thin topic organs composing nx_research_engine (rule-15 DRY correction). Uses unlinkat(263) -- the ecosystem's 3// own delete (the nx_cad_nas_probe precedent), NOT a shell rm. Idempotent: confirms each file is gone after unlink. 4// expect_exit: 0 license_tier: ORIGINAL 5import "nx_syscalls.nx" 6import "nx_itoa_lib.nx" // shared MSB-first emitter (zero-alloc) 7 8func g_puts(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(1,s,n); return 0 } 9// MIGRATED to the shared emitter (debt 1785563586).
