Package lexical-graph Problem statement OpenSearch error handling has minimal test coverage (only NotFoundError retry tested). Neptune error tests already exist in test_neptune_graph_stores.py. Checkpoint, cascading deletion, and multi-tenant vector store have no error-path tests. Related: #408 Proposed solution OpenSearch: connection timeout, bulk insert partial failure, auth failure (403), index_exists 404 handling Checkpoint: missing directory, unreadable file (PermissionError), read-only filesystem delete_sources: error mid-cascade propagation, empty source_ids list Multi-tenant: query/write with wrong tenant scoped correctly, no cross-tenant leakage Alternatives considered No response

Package lexical-graph Problem statement 11 graph builder methods generate Cypher via f-strings. Tests verify call counts but never assert on query string content — structurally invalid Cypher (like #408's WHERE () AND ...) passes all tests. source_graph_builder has no test file at all. test_delete_sources.py and test_entity_graph_builder_label_injection.py already assert on query strings — this targets the remaining builders. test_version_manager.py only tests version numbering (get/set/increment/compare). Query generation, source node lookup, lifecycle orchestration, and vector store updates have zero coverage. Related: #408, #415 Proposed solution Add at least one query-string assertion per builder method (11 total: source, graph_summary, entity, entity_relation, topic, fact, statement, chunk builders + version_manager._get_existing_source_nodes + delete_sources.accept + neo4j_graph_store.init) Test VersionManager state transitions: first-time indexing, re-indexing with existing

Package lexical-graph Problem statement graph_utils.py functions lack boundary and edge-case test coverage. test_graph_utils.py covers happy paths; test_graph_utils_injection.py covers basic injection patterns (6 tests). The remaining gaps: parse_metadata_filters_recursive: NOT + empty filters, 3-level nesting, mixed children types escape_cypher_label: empty string, only-backtick, newline inputs formatter_for_type: empty string input Adversarial escaping: unicode null bytes, homoglyphs, oversized keys (10KB+), newlines in keys, nested backtick+quote combos, values containing Cypher syntax, non-string metadata values Related: #408, #415 Proposed solution Extend test_graph_utils.py and test_graph_utils_injection.py with the above edge cases.
