 # Changelog
 
+## 2025-11-17 - 2.7.3 - fix(tsbuild.classes)
+Remove duplicate emitDecoratorMetadata from default compiler options and centralize it in protected defaults
+
+- Removed emitDecoratorMetadata from compilerOptionsDefault in ts/tsbuild.classes.tsbuild.ts to avoid duplicate configuration.
+- emitDecoratorMetadata remains enforced via getCriticalDefaults(), ensuring decorator metadata support is protected from tsconfig.json overrides.
+- Prevents inconsistencies during compiler option merging by centralizing the decorator-related setting.
+
 ## 2025-11-17 - 2.7.2 - fix(compilerOptions)
 Remove experimentalDecorators and useDefineForClassFields from default TypeScript compiler options
