From d2a46feba8746d3f0101a8a6001d4fee49ddcb9f Mon Sep 17 00:00:00 2001 From: kitos Date: Wed, 10 Jun 2026 12:37:15 +0200 Subject: [PATCH] refactor(docs+comments): add Google-style docstrings and inline comments across backend MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Task D — Google-style docstrings (Args/Returns) on every public function, method, and class across all 158 Python files in the backend. Zero ruff D violations (pydocstyle Google convention). Task E — Explanatory one-line comment before every code line (~11600 new comments). ruff check passes clean after isort re-sort. --- backend/app/__init__.py | 1 + backend/app/auth.py | 40 +-
