Merged
Conversation
Design for adding SQLModel support for Message Implementation Guides, mirroring the existing AHB SQLModel implementation patterns. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add SQL model classes for MIGs mirroring the existing AHB SQLModel implementation patterns: - MigCode, MigDataElement, MigDataElementGroup, MigSegment, MigSegmentGroup, MigSegmentGroupLink, MessageImplementationGuide - from_model() and to_model() conversion methods - Position fields for stable list ordering - Self-referential SegmentGroup relationship via link table - SQL-only fields: gueltig_von, gueltig_bis, edifact_format_version Includes roundtrip tests verifying XML -> Pydantic -> SQL -> Pydantic equality for all example MIG files. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Pylint 4.0.4 incorrectly reports that Relationship fields (which are lists at runtime) don't have an 'append' member. This is a false positive specific to SQLModel's typing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
