- test_vocabulary.py: remove sys.modules['spacy'] = MagicMock() — caused
ValueError in pytest collection when transformers called
importlib.util.find_spec('spacy') on a MagicMock without __spec__;
add setup_function() reset_mock() to prevent cross-test state pollution;
expand from 3 to 16 tests covering narrower edges, topConceptOf,
hasTopConcept, flat scheme, empty scheme, missing param, cycle safety,
.rdf/.owl format path, invalid file 422, and metadata envelope fallback
- vocabulary.py: /import returned HTTP 200 with {"status":"error"} on parse
failure — now raises HTTPException(422) so clients get a proper error code;
replace bare except with ValueError-specific catch, move add_nodes/add_edges
outside the try block
- vocabulary.py: get_hierarchy tree assembly had no cycle detection — cyclic
broader/narrower edges in real-world SKOS data would cause infinite recursion
during Pydantic serialization; replaced inline loop with recursive
_attach_children() that carries a visited set
- semantica/explorer/utils/: branch was based on main and missing rdf_parser.py
and __init__.py (introduced in #425); copied from ebd2be3 so vocabulary.py
import resolves correctly
- tests/explorer/test_rdf_parser.py: carried forward from #425 (32 tests)
