**Summary**

- Add `@json-render/yaml` package with streaming parser, YAML prompt generation, and AI SDK transform
- Add universal edit modes (patch, merge, diff) to `@json-render/core`, usable across both JSONL and YAML formats
- Integrate YAML support and edit mode selection into the web playground with format toggle, token usage display, and prompt caching

* improvements

* fixes

+## Edit Modes
+
+Universal edit mode utilities for modifying existing specs. Used by `buildUserPrompt` internally and available for direct use.
+
+```typescript
+import {
+  buildEditInstructions,
+  buildEditUserPrompt,
+  isNonEmptySpec,
+  type EditMode,
+  type EditConfig,
+} from '@json-render/core';
+
+type EditMode = "patch" | "merge" | "diff";
+```
+
+### buildEditInstructions
+
+Generate the prompt section describing available edit modes. Supports both JSON and YAML formats.
+
+```typescript
+function buildEditInstructions(config: EditConfig, format: "json" | "yaml"): string
+
+const instructions = buildEditInstructions({ modes: ["patch", "merge"] }, "json");
+```
+
+### buildEditUserPrompt
+
+Build a user prompt for editing an existing spec. Includes the current spec (with line numbers when diff mode is enabled) and mode-specific instructions.
+
+```typescript
+function buildEditUserPrompt(options: BuildEditUserPromptOptions): string
+
+interface BuildEditUserPromptOptions {
+  prompt: string;
+  currentSpec?: Spec | null;
+  config?: EditConfig;
+  format: "json" | "yaml";
+  maxPromptLength?: number;
+  serializer?: (spec: Spec) => string;
+}
+```
+
+### isNonEmptySpec
+
+Check whether a value is a non-empty spec (has a root string and at least one element).
+
+```typescript
+function isNonEmptySpec(spec: unknown): spec is Spec
+```
+
+## Deep Merge and Diff
+
+Format-agnostic utilities for merging and diffing spec objects.
+
+### deepMergeSpec
+
+Deep-merge with RFC 7396 semantics: `null` deletes, arrays replace, objects recurse. Neither input is mutated.
+
+```typescript
+import { deepMergeSpec } from '@json-render/core';
+
+function deepMergeSpec(
+  base: Record<string, unknown>,
+  patch: Record<string, unknown>
+): Record<string, unknown>
+
+const merged = deepMergeSpec(currentSpec, { elements: { main: { props: { title: "New" } } } });
+```
+
+### diffToPatches
+
+Generate RFC 6902 JSON Patch operations that transform one object into another. Arrays are compared shallowly and replaced atomically; plain objects recurse.
+
+```typescript
+import { diffToPatches } from '@json-render/core';
+
+function diffToPatches(
+  oldObj: Record<string, unknown>,
+  newObj: Record<string, unknown>,
+  basePath?: string
+): JsonPatch[]
+
+const patches = diffToPatches(oldSpec, newSpec);
+// [{ op: "replace", path: "/elements/main/props/title", value: "New Title" }]
+```
+

+```
+
+## Components
+
+### Renderer
+
+```tsx
+<Renderer spec={spec} registry={registry} loading={false} />
+```
+
+Renders a `Spec` tree using your registry.
+
+### createRenderer
+
+Build an app-level renderer from catalog + components:
+
+```tsx
+const AppRenderer = createRenderer(catalog, {
+  Card: (renderProps) => <div>{renderProps.children}</div>,
+});
+
+<AppRenderer spec={spec} state={{}} onAction={(name, params) => {}} />;
+```
+
+## Hooks
+
+- `useStateStore()`
+- `useStateValue(path)` - returns an accessor
+- `useStateBinding(path)` - returns `[Accessor<T | undefined>, setValue]`
+- `useVisibility()` / `useIsVisible(condition)`
+- `useActions()` / `useAction(binding)`
+- `useValidation()` / `useOptionalValidation()`
+- `useFieldValidation(path, config)` - returns accessor-backed `state`, `errors`, and `isValid`
+- `useBoundProp(value, bindingPath)`
+- `useUIStream(options)`
+- `useChatUI(options)`
+
+## Built-in Actions
+
+`ActionProvider` handles these built-in actions:
+
+- `setState`
+- `pushState`
+- `removeState`
+- `validateForm`
+
+## Component Props
+
+Registry components receive:
+
+```ts
+interface ComponentRenderProps<P = Record<string, unknown>> {
+  element: UIElement<string, P>;
+  children?: JSX.Element;
+  emit: (event: string) => void;
+  on: (event: string) => EventHandle;
+  bindings?: Record<string, string>;
+  loading?: boolean;
+}
+```
+
+Use `emit("event")` to dispatch event bindings. Use `on("event")` to access `EventHandle` metadata (`bound`, `shouldPreventDefault`, `emit`).
+
+## Reactivity Notes
+
+- Keep changing reads in JSX expressions, `createMemo`, or `createEffect`.
+- Avoid props destructuring in component signatures when you need live updates.
+- `StateProvider` and other contexts expose getter-backed values so consumers read live signals.
+- `useStateValue`, `useStateBinding`, and `useFieldValidation` expose reactive accessors; call them as functions.
