Review Comment:
**Suggestion:** Replace the unannotated walrus assignment with an explicitly
declared, typed local variable before the conditional check. [custom_rule]
**Severity Level:** Minor ⚠️
<details>
<summary><b>Why it matters? 🤔 </b></summary>
The rule requires type hints for relevant variables that can be annotated in
new or modified Python code. This new walrus assignment introduces the local
variable `existing` without any type annotation, so the suggestion accurately
identifies a real rule violation.
