nx_char_identity.nx

nx_char_identity.nx -- THE IDENTITY VECTOR: "a LoRA, but for riggable models" (operator 2026-07-27: "daz like models or whatever powers lust goddesses or nikke ... an emitter or proc generator but wireable, making CONSISTENT beauties almost like a lora on a diffusion but for riggable models"). WHAT A LoRA ACTUALLY IS, mechanically: a SMALL reproducible DELTA applied to a big frozen base, such that the same delta yields the same identity every time, under any prompt. The riggable equivalent is exactly the DAZ Genesis architecture: ONE base topology + a MORPH-DIAL VECTOR + a shared rig. Same dials => same woman, in any pose, any outfit, any art style. This organ is that dial vector. ★THE LAW IT ENFORCES (already written in nx_scene_contract.nx:9-13, now made GATE-ABLE): identity = f(seed) ONLY. STYLE transforms proportions and shading; it must NEVER touch identity. That single invariant is what "consistent beauties" means operationally, and T2 of the gate proves it. ★WHAT IT REUSES (check-before-build; none of this is rebuilt here): nx_morph.nx -- mo_begin/mo_add_delta/mo_apply: 32 dials x 0..256 weights, ADDITIVE and COMMUTATIVE, applied to the bind-pose mesh before skinning (industry standard). THE dial primitive. This organ emits weights FOR it. nx_body_proc.nx -- seed + {sex,build,musc,noise,stylize,eyecol} -> canon.dat, already deterministic and already carrying a realistic<->ANIME stylize axis (0..1000). nx_scene_contract -- the per-style proportion tables (anime head-ratio 205 vs realistic 137). nx_bodyatlas -- the base body + the 9-bone FK rig that glTF export already skins against. nx_canon_cid.nx -- the DURABLE character id (nxc1-<sha256>) at publish time. `idv_key` below is a fast in-memory dedup key ONLY, deliberately a different thing, not a rival CID. ★★WHAT IT REFUSES TO DO, AND WHY (the honest boundary): It does NOT score beauty. [[reference-beauty-canon-and-layered-anatomy-2026-07-26]]: Versluys 2018 found the aesthetic optimum FLIPS with stimulus realism -- silhouettes optimise BELOW baseline, detailed CG ABOVE. We render at clay fidelity, so a beauty judge calibrated here would teach the WRONG target and actively make the models worse. What IS honestly gate-able is CONSISTENCY, DIVERSITY, and conformance to MEASURED anthropometry -- so that is all this gates. Aesthetic judgement belongs to the high-fidelity lane, at the fidelity it will be used at. ★★AND IT HARD-REFUSES PHI: the golden ratio is ACTIVELY REFUTED for human proportion (Naini 2024; Burusapat 2019 measured 32 Miss Universe winners: "statistically significantly invalid"). WHR 0.7 is dead too -- our own ANSUR II parse found 0.0% of 1,986 women reach it. The gate carries a REGRESSION TOOTH so nobody can quietly reintroduce either. All integer, deterministic. LIB, no main. license_tier: ORIGINAL
