nx_nishilang_norm.nx

nx_nishilang_norm.nx -- THE GENERAL-MODEL BRIDGE (autonomous-builder lane, 2026-07-20). The maker-climb root cause (NB7): a strong GENERAL coder (Qwen-class, coder15) emits `else if` / `else` blocks that NishiLang has no keyword for -> build breaks. This normalizer rewrites those into valid NishiLang EARLY-RETURN form so any off-the-shelf coder's output compiles. SOUND by construction of the loop: the transform is only a SYNTAX rewrite; the symbolic judge (nx_symjudge) then property-verifies the normalized fix over an exhaustive sweep, so a mis-normalization is caught (fail-closed) -- never a silent wrong fix. Rewrites (semantics-preserving for return-bodies): `} else if C {` -> `} if C {` (else-if chain -> separate early-return ifs) `} else { E }` -> `} E ` (strip the else wrapper + its matching close brace) argv: <infile> <outfile> (reads generated-fix text, writes normalized NishiLang) exit: 0 wrote | 2 io. Idempotent (already-valid NishiLang passes through byte-unchanged). license_tier: ORIGINAL No hw writes (Rule 26).
