1// nx_studio_tiers.nx -- CAPABILITY-ADAPTIVE WYSIWYG (operator's idea: let users select, by their capability, 2// HOW they want to build). The editor offers tiers -- GUIDED (novice/elderly: answer a few fields, the 3// structure is guaranteed), BLOCK (intermediate: arrange blocks), FREE-FORM (power: place freely) -- but ALL 4// tiers normalize to the ONE governed, portable .site data model and build through the SAME sovereign engine 5// (se_build_site). So escaping, the publish-time UX gate, and portability are INVARIANT across tiers: no 6// capability tier can escape governance. tier_normalize is the single funnel. 7// GUIDED : a compact answer set (brand|.. headline|.. cta|.. ..) -> a COMPLETE compliant .site by 8// construction (every required block is in the template; missing answers fall back to defaults), 9// so a novice CANNOT produce a broken page. 10// FREE-FORM: a .site plus layout-only `place|idx|x|y` lines -> the placement lines are stripped to the 11// governed block .site (free placement is a presentation hint, never a way around the engine). 12// BLOCK : already a .site -> passthrough. 13// license_tier: ORIGINAL 14import "nx_sitegen_studio.nx" 15import "nx_sitegen_freeform.nx" 16import "nx_syscalls.nx" 17const TIER_MAGIC_65536: i64 = 65536 18const TIER_MAGIC_65535: i64 = 65535 19 20const TIER_GUIDED: i64 = 0 21const TIER_BLOCK: i64 = 1 22const TIER_FREEFORM: i64 = 2 23 24func tn_strlen(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} return n } 25func tn_puts(out: *u8, off: i64, s: *u8) -> i64 { var o: i64=off; var k: i64=0; while s[k]!=(0 as u8){out[o]=s[k];o=o+1;k=k+1} return o } 26func tn_putrange(out: *u8, off: i64, src: *u8, a: i64, b: i64) -> i64 { var o: i64=off; var j: i64=a; while j<b { out[o]=src[j]; o=o+1; j=j+1 } if o>off { if (out[o-1] as i64)==13 { o=o-1 } } return o } 27 28// does input[ls..le) start with key followed by '|'?
