Conversation
…#1226) Phase 3 of graph memory epic (#1222): augment existing recall with graph traversal, scoring, and context injection. - Add graph_recall function with fuzzy word-split entity matching, depth-tracked BFS expansion, composite scoring, and deduplication - Add bfs_with_depth to GraphStore with MAX_FRONTIER=300 guard against SQLite bind variable limit - Add MemoryRoute::Graph variant with RELATIONSHIP_PATTERNS heuristic - Add BudgetAllocation.graph_facts (4% when graph-memory enabled) - Add recall_graph method to SemanticMemory with graph_store field - Add graph facts context injection with [known facts] prefix, fact-by-fact token budget enforcement, and sanitization - Add GraphConfig to MemoryState for runtime recall_limit/max_hops - Use f32::total_cmp for NaN-safe composite score sorting
