Phase 1 — Generation: - Add SHACLGenerator, SHACLGraph, NodeShape, PropertyShape to ontology_generator.py - 6-stage pipeline: class index → node shapes → property shapes → inheritance propagation → quality tier → serialization - Three output formats: Turtle, JSON-LD, N-Triples - Three quality tiers: basic / standard (default) / strict (sh:closed) - 3-level+ inheritance propagation, cycle-safe, no duplicate shapes - No-domain properties attach to all node shapes - OntologyEngine.to_shacl(), export_shacl() added to engine.py - RDFExporter.export_shacl() added to rdf_exporter.py Phase 2 — Runtime Validation: - Add SHACLViolation, SHACLValidationReport, _run_pyshacl to ontology_validator.py - OntologyEngine.validate_graph() with shacl= or ontology= arguments - explain_violations(): rule-based plain-English explanations for all 7 SHACL constraint types - summary(), to_dict() on SHACLValidationReport for pipeline and LLM consumers - pyshacl/rdflib are optional deferred imports (pip install semantica[shacl]) Security & reliability fixes: - Replace path-heuristic (len/newline) with os.path.exists() in validate_graph - Add shacl_format parameter to validate_graph and _run_pyshacl; thread format through correctly - Fix validate_output format alias map in to_shacl (json-ld, n-triples aliases) - Deep-copy PropertyShape in _propagate_inheritance (dataclasses.replace) — no shared mutable refs - Deterministic Turtle prefix output via sorted(graph.prefixes.items()) - Use full rdf:type URI in sh:ignoredProperties — no prefix dependency Tests & docs: - Add TestSHACLGeneration (16 tests) to test_ontology_comprehensive.py - Add TestSHACLHierarchicalAndValidation (18 tests) to test_ontology_advanced.py - 34 new tests, 0 failures, 0 regressions across 1111-test suite - Update README: Unreleased section, Features, Modules table, Ontology code block, Installation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
