- Log messages, script output, test labels, Makefile errors and comments are English. Red log lines start with "[RED] " (was 【红】). - Shader map stage column: vertex / pixel / compute / geometry / hull / domain (generators, dmsh_build / dmsh_facts and nvn_mtl.m stage_of follow). - The NSP script's regexes match the new shader_split.py / dmsh_build.py summary lines; patch_nso cut scopes are all / host-only. - Host UI text table (dm_i18n_tab.h) is English only; dm_lang_zh() removed. - Text that matches game data (t_swkbd.c, t_textbox.c) is written as \x escapes. - Shader chain: the chain files lose their bilingual comments, so every profile has a new chain version. dmsh_xlate.dll rebuilt from the translated Program.cs (SPIR-V byte-identical on 4,500 shaders of Wonder, TOTK and Age of Calamity), lock and dmsh_chain.h headers regenerated. c1_full.tsv restamped for Dread, 13 Sentinels and Wonder; the other profiles follow when their rebuild finishes. - AGENTS.md and docs/agents: the language rule now covers logs; quoted log lines updated.
