From 52de48ec6063e59d403a90dccc7755def45d7f4f Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 6 Jun 2026 16:02:09 +0000 Subject: [PATCH 1/4] Refactor handle_messages to reduce nesting by adding early return The `handle_messages` function in `notifications.py` had a deeply nested structure for checking the MQTT topic path segments. This commit adds an early return (`if len(parts) < 3`) which significantly reduces the indentation and cognitive complexity of the function while preserving the exact same behavior (including appending the log with `user_id=None` when `len(parts) < 3`). Tests pass successfully.
