nx_code_embed_gate.nx -- SOVEREIGN CODE-EMBEDDING gate (2026-07-14). Grounds the jina-code-embeddings recipe (arXiv:2508.21290, backbone = Qwen2.5-Coder-0.5B = OUR coder) on the no-float stack: embedding = last-token pooled final-norm hidden state = nsv_embed(). Task instruction prefixes = jina's EXACT strings. GATES (liar-killer style): A ORDER jina model-card 2x2 demo: cos(q1,p1)>cos(q1,p2) AND cos(q2,p2)>cos(q2,p1) (bf16 jina-tuned oracle values 817/124/120/553 pm -- we gate ORDER only: base weights differ) B DETERM re-embed q1 AFTER all other texts -> vector must be BITWISE IDENTICAL (catches KV/state leak) C SELF cos(q1,q1') >= 999 pm (isqrt floor can give 1000+/-1) D RETRIEVE 3x3 Nishi-corpus NL->code argmax must hit the diagonal 3/3 E API synthetic HTTP POST /embed through nsv_handle -> 200 + ok:1 + dim:896 (the daemon serves these exact bytes -> the capability is API-reachable, rule-27 style, not gate-only) HONEST SCOPE: this proves PIPELINE CORRECTNESS on BASE coder weights. SOTA retrieval quality is NOT claimed -- that grading pends the jina-weight oracle (cc-by-nc-4.0 -> benchmark-only, like gcc). license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
