+- **Creating variables** → `gotcha/variables.md` (RegEx Table column names)
+- **Writing regex conditions** → `gotcha/regex.md` (RE2 limitations)
+- **Batch changes / publishing** → `gotcha/compilation.md` (workspace lifecycle)
+- **Using DTM CLI** → `gotcha/dtm-cli.md` (commands that don't actually work)
