+# Files Moved
+
+The files in `superclaude/core/` have been reorganized into domain-specific directories:
+
+## New Structure
+
+### Framework (思想・行動規範・グローバルフラグ)
+- `PRINCIPLES.md` → `superclaude/framework/principles.md`
+- `RULES.md` → `superclaude/framework/rules.md`
+- `FLAGS.md` → `superclaude/framework/flags.md`
+
+### Business (ビジネス領域の共通リソース)
+- `BUSINESS_SYMBOLS.md` → `superclaude/business/symbols.md`
+- `BUSINESS_PANEL_EXAMPLES.md` → `superclaude/business/examples.md`
+
+### Research (調査・評価・設定)
+- `RESEARCH_CONFIG.md` → `superclaude/research/config.md`
+
+## Rationale
+
+The `core/` directory was too abstract and made it difficult to find specific documentation. The new structure provides:
+
+- **Clear domain boundaries**: Easier to navigate and maintain
+- **Scalability**: Easy to add new directories (e.g., `benchmarks/`, `policies/`)
+- **Lowercase naming**: Consistent with modern documentation practices
+
+## Migration
+
+All internal references have been updated. External references should update to the new paths.
+
+This directory will be removed in the next major release.
