From 12a444e7f93fd866c72fd186ad8f6634f0bac5d3 Mon Sep 17 00:00:00 2001 From: Tobias Knecht Date: Tue, 13 Jan 2026 14:15:14 +0100 Subject: [PATCH 1/6] feat: add schema-driven validation infrastructure (Phase 1) - Bundle XARF v4 JSON schemas from xarf-spec (35 schema files) - Add schema_utils.py for schema file discovery and loading - Add SchemaRegistry singleton for centralized schema access - Dynamic category/type validation from schemas - Field metadata extraction (required, optional, recommended) - Evidence source validation - Category-specific field discovery - Add SchemaValidator for JSON Schema validation using jsonschema - Validates against core schema and type-specific schemas - User-friendly error messages - Support for all 7 categories and 33 types - Add comprehensive tests (67 new tests, all passing) - Update pyproject.toml to include schemas in package - Export new classes from xarf package This aligns xarf-python with xarf-javascript reference implementation. ---

Update ContactInfo to use 'domain' instead of 'type' - Add required 'sender' field to XARFReport - Make 'evidence_source' optional (recommended) - Add ValidationResult dataclass for validate() method - Update v3 converter to produce v4-compliant output - Update all tests to use v4-compliant test data - Add shared test fixtures in conftest.py Also: - Replace black/isort/flake8/bandit with ruff in pre-commit - Modernize type annotations (dict instead of Dict, etc.) - Fix trailing whitespace and EOF issues in sample files --- .github/QUICK_START.md | 2 +- .pre-commit-config.yaml | 66 +-- CODE_OF_CONDUCT.md | 1 -
