Thread-safe data persistence in Swift using actors with in-memory cache and file-backed storage. \n \n Implements an actor-based repository pattern that eliminates data races at compile time, replacing manual synchronization with Swift's actor model \n Combines fast O(1) in-memory lookups with atomic file persistence, supporting any Codable & Identifiable model type \n Provides synchronous initialization to avoid async complexity, with automatic await enforcement on all public API calls \n

Durable graph execution with thread-scoped checkpoints, state history, and cross-thread long-term memory. \n \n Three checkpointer options: InMemorySaver for testing, SqliteSaver for local development, PostgresSaver for production; always pass thread_id in config to enable persistence \n Browse and replay from past checkpoints using get_state_history() , fork execution by updating state at a past point, or manually modify state before resuming \n Store API provides cross-thread memory for user p
