+#### Yarn Line Tag Maintenance
+- **Line tags** (`#line:xxxxxxx`) must be unique across the entire file. Duplicate tags break Yarn Spinner localization.
+- Duplicates typically occur when copying an existing node to create a variant (e.g. `地铁ver1` → `地铁ver3`).
+- **Use the dedup tool** (`Tools/dedup_yarn_tags.py`) for bulk cleanup:
+  ```bash
+  # Preview duplicates from a specific node onward
+  python Tools/dedup_yarn_tags.py Assets/Resources/Yarn/Fiction_Day1_begin/Fiction_Day1_begin.yarn --from-node 地铁ver4
+  # Fix duplicates from a specific line onward
+  python Tools/dedup_yarn_tags.py Assets/Resources/Yarn/Fiction_Day1_begin/Fiction_Day1_begin.yarn --from-line 535 --fix
+  # Scan an entire directory (preview only)
+  python Tools/dedup_yarn_tags.py Assets/Resources/Yarn/ --scan-all
+  ```
+
+#### Yarn Script Generation
+- **Do NOT add `#line:` tags when generating or editing Yarn dialogue.** Leave all line-tag generation to the user's localization workflow (Unity Localization + Yarn Spinner import tools).
+- When creating new `.yarn` files, write plain dialogue lines without any `#line:` suffixes.

 ### Asset Naming
 - **Scripts**: PascalCase (e.g. `DialogController.cs`)
 - **Addressable Keys**: `Category/Path` — no spaces, no extensions, ≤3 levels
