- Add neo4j>=5.0 to requirements.txt
- New lore_engine_poc/neo4j_graph.py: Neo4jGraph class implementing
the GraphBackend Protocol skeleton (reified :Relation shape per
ADR 0009):
* Lifecycle: __init__, close, ensure_schema (idempotent
constraints on Entity.name_lower, LoreSource.path,
Relation.edge_id)
* Reads (slice 5.3 ships minimum; 5.4 fills the rest):
by_name, all_names, all_entity_types, entities_of_type,
lore_source, find_edge_by_id (returns None), edges_for_* (stub)
* Writes (slice 5.3 ships entity/source helpers; 5.5 fills rest):
add_entity_of_type (SET n:Label for dynamic label, no APOC
dep on community image), register_name, register_alias (Alias
node + CANONICAL_OF edge), add_lore_source; add/replace_edge/
remove_entity/remove_entity_of_type/rename_entity (stubs)
- _sanitize_label() helper: strip non-[A-Za-z0-9_] from dynamic
labels so SET n:Label is safe to interpolate
- 12 docker-gated tests in test_neo4j_graph.py: connects, schema
idempotent, add_node creates typed node, upsert semantics,
case-insensitive by_name, alias fallback, dynamic label, find by
id returns None, driver reconnect, HTTP probe, bolt protocol v5,
module-scoped fixture reuses driver
- Test gating: skipif(!HAS_DOCKER || !neo4j reachable); module
fixture reuses one driver; function-scoped fixture wipes state
per test so ordering doesn't matter
- Used neo4j GraphDatabase with auth=none (loopback only, per
the plan's NEO4J_AUTH=none)
Suite: 584 -> 596 passed (+12 new tests, 559 baseline preserved)
