description: "Observable browser state stores with explicit snapshots, subscriptions, and lifecycle ownership."
English | 中文
React-free observable and snapshot-store primitives shared by Client controllers and renderer adapters. The package owns synchronous and animation-frame publication, Immer-backed updates, shallow equality, and optional browser persistence; React hook construction remains in @deepseek-ai/dsh-client-ui-renderer. Use it when Client state must publish stable snapshots without depending on React.
None, as this package provides browser-side state primitives and registers nothing model-facing.
None; the stores neither assemble nor send model requests.
localStorage; non-browser runtimes disable persistence, and the package provides no cross-device synchronization.Runtime invariant: No companion is published. The package exports a library engine and creates no process-global state; each store instance is covered by its owning tests.
