From 3743ed4ca8d01534ab4449709aa1881363299bf6 Mon Sep 17 00:00:00 2001 From: Pier-Jean Malandrino Date: Tue, 31 Mar 2026 10:34:07 +0200 Subject: [PATCH 1/9] Refactor backend to hexagonal architecture for converter extensibility Extract domain value objects and ports from parsing.py, move Docling-specific code to infra/local_converter.py, and convert analysis_service to a class with injected DocumentConverter. This prepares the codebase for plugging in alternative conversion backends (e.g. Docling Serve) via the Protocol pattern.
