 ## Common Mistakes
 
 - **Forgetting `translatable="false"`** — these should never appear in locale files
 - **Not checking string-arrays/plurals** — only checking `<string>` misses other resource types
-- **Modifying files** — this is a read-only research task unless the user asks to add entries
\ No newline at end of file
+- **Diffing each locale separately** — only diff against `cs-rCZ`; assume the same keys are missing everywhere
+- **Inserting strings in a specific position** — always append at the bottom; ordering is handled separately
