+# Bootstrap Architecture
+
+PraisonAIUI provides a unified bootstrap entrypoint through `aiui run app.py` that automatically detects and handles different application patterns.
+
+## Supported Patterns
+
+### 1. Chat Applications
+```python
+import praisonaiui as aiui
+
+@aiui.reply
+async def on_message(message: str):
+    await aiui.say(f"You said: {message}")
+```
+
+**Run**: `aiui run app.py`
+
+### 2. Dashboard Applications  
+```python
+from praisonaiui.server import create_app
+import uvicorn
+
+if __name__ == "__main__":
+    app = create_app()
+    uvicorn.run(app, host="0.0.0.0", port=8082)
+```
+
+**Run**: `aiui run app.py` (automatically detects `create_app()` pattern)
+
+### 3. Gateway Applications
+```python
+import asyncio
+from praisonaiui.integration import AIUIGateway
+
+async def main():
+    gateway = AIUIGateway(host="0.0.0.0", port=8083)
+    # ... register agents
+    await gateway.start()
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+**Run**: `aiui run app.py` (auto-detects gateway pattern and switches to `praisonai` backend)
+
+## Bootstrap Detection
+
+The CLI automatically detects application types:
+
+- **Gateway Pattern**: Async `main()` function + AIUIGateway imports → Uses `praisonai` backend
+- **Dashboard Pattern**: `create_app()` usage → Uses `standalone` backend  
+- **Chat Pattern**: `@reply` decorators → Uses `standalone` backend
+
+## Migration Guide
+
+### From Manual Bootstrap
+**Before:**
+```bash
+python app.py
+```
+
+**After:**
+```bash
+aiui run app.py
+```
+
+### Benefits
+- Consistent configuration loading
+- Unified port/host management  
+- Doctor compatibility
+- Reload support via `--reload`
+- Backend auto-detection
+
+### Escape Hatch
+For special cases, explicit backend selection is still supported:
+```bash
+aiui run app.py --backend praisonai  # Force gateway backend
+aiui run app.py --backend standalone # Force standalone backend
+```

+
+Any provider can attach rich media to chat messages using ``MESSAGE_ELEMENT``
+events. The UI renders them inline and persists them in session history.
+
+```python
+class ImageProvider(BaseProvider):
+    async def run(self, message, *, session_id=None, agent_name=None, **kw):

+            "alt": "Generated image",
+        })
+        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Here is your image.")
+```
+
+Tool results from PraisonAI agents are also detected automatically when they
+match OpenAI image shapes (``{"data": [{"url": "..."}]}``) or explicit element
+dicts — no provider code required.
+
+Callback handlers can use ``Message.add_image()`` or ``await aiui.image(url)``
+and the default ``PraisonAIProvider`` maps those to ``MESSAGE_ELEMENT`` events.

+# A2UI canvas — agent-driven UI
+
+PraisonAIUI hosts **A2UI v0.9** surfaces: agents push structured UI messages to a live canvas while users chat in the same window or on a full-page workspace.
+
+For dashboard extension patterns (views, plugins, layout JSON), see [Agent UI host](agent-ui-host.md).
+
+## Quick start
+
+```python
+import praisonaiui as aiui
+
+aiui.set_style("dashboard")
+aiui.set_chat_preview(enabled=True, surface_id="main", width="38%")
+aiui.set_pages(["chat-canvas", "chat", "canvas"])
+
+@aiui.page("agent-canvas", title="Agent Canvas", icon="🖼️")
+async def agent_canvas():
+    return {"_surface": {"id": "main", "messages": []}}
+
+@aiui.surface_action("main")
+async def on_surface_action(action: dict):
+    return {"received": action}
+```
+
+Run the full example: [`examples/python/30-a2ui-canvas/app.py`](../../examples/python/30-a2ui-canvas/app.py).
+
+## Dashboard pages
+
+| Page id | Route | Purpose |
+|---------|-------|---------|
+| `chat-canvas` | `/chat-canvas` | Split view — chat left, live A2UI preview right |
+| `chat` | `/chat` | Vanilla chat (unchanged) |
+| `canvas` | `/canvas` | Full-page surface workspace |
+
+Enable the split preview with [`set_chat_preview`](../api/python.md#set_chat_previewenabled-surface_id-width). Settings appear in `/ui-config.json` as `chat.preview: { enabled, surfaceId, width }`.
+
+## Agent integration
+
+Agents should call **`send_a2ui_messages`** (from `praisonaiagents.tools.a2ui_tools`) with A2UI message dicts:
+
+```python
+send_a2ui_messages(messages=[
+    {"createSurface": {"surfaceId": "main", "catalogId": "basic"}},
+    {"updateComponents": {"components": [
+        {"component": "Text", "text": {"literal": "Hello"}},
+        {"component": "Button", "text": {"literal": "Submit"},
+         "action": {"name": "handleSubmit"}},
+    ]}},
+])
+```
+
+Wrap the tool with **`coerce_a2ui_tool_messages`** so common LLM argument shapes still work:
+
+```python
+from praisonaiui.a2ui_utils import coerce_a2ui_tool_messages
+
+@tool
+def send_a2ui_messages(messages):
+    coerced = coerce_a2ui_tool_messages(messages, surface_id="main")
+    return sdk_send_a2ui(messages=coerced)
+```
+
+`coerce_a2ui_tool_messages` accepts:
+
+- A JSON string or list of message dicts
+- A dict with a `messages` key
+- A bare `components` list (wrapped in `updateComponents`)
+- A single component dict (wrapped in `updateComponents`)
+- Missing `createSurface` (inserted automatically for the given `surface_id`)
+
+Tool results are detected by [`a2ui_utils`](../../src/praisonaiui/a2ui_utils.py) and ingested into the surface store; connected clients receive WebSocket `a2ui_surface` events.
+
+## HTTP API
+
+| Method | Path | Behaviour |
+|--------|------|-----------|
+| `GET` | `/api/surfaces` | List surfaces and message counts |
+| `GET` | `/api/surfaces/{id}` | Surface state; **200 with `{ messages: [] }`** if not created yet (empty canvas is normal) |
+| `POST` | `/api/surfaces/{id}/messages` | Append or replace messages (`replace: true` in body) |
+| `POST` | `/api/surfaces/{id}/actions` | User action from a button/component |
+| `DELETE` | `/api/surfaces/{id}` | Clear surface |
+
+Realtime updates use the existing dashboard WebSocket (`a2ui_surface` payload).
+
+## CLI
+
+Manage surfaces against a running server (`--server` / `AIUI_SERVER`, default `http://127.0.0.1:8000`):
+
+```bash
+aiui surface list
+aiui surface get main
+aiui surface get main --json
+aiui surface push main --file messages.json
+aiui surface push main --file messages.json --replace
+aiui surface clear main
+aiui surface status
+```
+
+`messages.json` must contain `{ "messages": [ ... ] }`.
+
+## Frontend modules
+
+Shared dashboard JS (lazy-loaded with `chat-canvas`):
+
+| Module | Role |
+|--------|------|
+| `surface-utils.js` | Load surface, WebSocket sync, post actions |
+| `canvas-preview.js` | Right-hand preview panel |
+| `a2ui-mapper.js` | Default DOM mapper (Text, Button, Column, Row, Card, …) |
+| `plugins/views/chat-canvas.js` | Composes chat + preview without modifying `chat.js` |
+
+Override rendering: `window.aiui.registerSurfaceRenderer("main", fn)`.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---------|--------------|-----|
+| Chat works but canvas stays empty | Agent did not call `send_a2ui_messages` | Strengthen instructions; wrap tool with `coerce_a2ui_tool_messages` |
+| Tool error / invalid JSON | LLM passed wrong shape | Use coercion wrapper; include schema prompt from `praisonaiagents.ui.a2ui.adapter` |
+| Preview shows raw JSON | Component type not in `a2ui-mapper` | Extend mapper or use supported components |
+| `GET /api/surfaces/main` empty | Normal before first push | Push via agent or `aiui surface push` |
+| Button click does nothing | No `@aiui.surface_action` handler | Register handler for that `surface_id` |

+YAML / Python config → server (pages API, plugins.json) → dashboard.js shell
+                              ↓

+
+**Extension priority** (first match wins):
+
+1. `window.aiui.registerView(pageId, …)`
+2. Dashboard manifest plugins (`dashboard-plugins/*/manifest.json`)

+
+## `window.aiui` extension API
+
+| API | Purpose |
+|-----|---------|
+| `version` | Shell protocol version (`'1'`) |
+| `registerView(pageId, renderFn, cleanup?)` | Replace or add a full page renderer |
+| `registerComponent(type, renderFn)` | Override a layout component type |
+| `registerSurfaceRenderer(surfaceId, renderFn)` | Custom A2UI surface renderer |
+| `selectPage(pageId)` | Navigate programmatically (e.g. open full canvas) |
+| `registerSlot(name, renderFn)` | Inject DOM into named slots |
+| `sdk.fetchJSON(url, opts?)` | Authenticated fetch helper |
+| `sdk.el(tag, attrs?, children?)` | Small DOM builder |
+| `sdk.themeVar('--db-*', fallback?)` | Read theme CSS variables |
+| `sdk.createBoard(root, { fetch, pollMs? })` | Live board with optional polling |
+
+### Slots
+
+| Slot id | Where it renders |
+|---------|------------------|
+| `shell:sidebar:footer` | Bottom of sidebar (default: health hint) |
+| `page:{pageId}:toolbar` | Right side of page header |
+
+Register only what you need; omit slots you do not use.
+
+## Layout components (Python → JS)
+
+Define pages with `@aiui.page()` returning `aiui.layout([...])`. Types are implemented once in [`ui.py`](../../src/praisonaiui/ui.py) and [`dashboard.js`](../../src/praisonaiui/templates/frontend/plugins/dashboard.js).
+
+**Kanban / board:** use `aiui.board(columns=[...])`. Columns contain `id`, `title`, and `cards` (from `aiui.card()` or dicts). The shell renders via `renderBoard`, composing existing card renderers (DRY).
+
+## A2UI surfaces (agent-driven UI)
+
+Three tiers work together:
+
+| Tier | Mechanism | Use case |
+|------|-----------|----------|
+| Dashboard | `aiui.layout()` → `_components` | Python-authored pages |
+| A2UI | `send_a2ui_messages` → `SurfaceHost` | Agent-generated UI in chat/canvas |
+| AG-UI | `POST /agui` SSE | CopilotKit / external clients |
+
+Register an empty canvas page:
+
+```python
+@aiui.page("agent-canvas", title="Agent Canvas", icon="🖼️")
+async def agent_canvas():
+    return {"_surface": {"id": "main", "messages": []}}
+```
+
+Or use `@aiui.surface_action("main")` for button callbacks.
+
+**Full guide:** [A2UI canvas](a2ui-canvas.md) — chat-canvas split view, `send_a2ui_messages`, HTTP/CLI, `coerce_a2ui_tool_messages`, troubleshooting. Example: [`examples/python/30-a2ui-canvas/`](../../examples/python/30-a2ui-canvas/app.py).
+
+## Optional dashboard modules
+
+Load heavy built-ins only when listed:
+
+```python
+aiui.set_dashboard(modules=["jobs", "auth", "api"])
+```
+
+```yaml
+dashboard:
+  modules: [jobs]
+```
+
+This adds `jobs.js`, `auth.js`, or `api.js` to the plugin chain and maps them in `BUILTIN_VIEWS`. `feedback` is always available as a built-in view when the page is enabled.
+
+## Third-party dashboard plugins
+
+Place folders under:
+
+- `~/.praisonai/dashboard-plugins/{name}/`
+- Or `src/praisonaiui/templates/frontend/dashboard-plugins/{name}/` (shipped examples)
+
+Each plugin needs `manifest.json` + `index.js` (optional `styles.css`):
+
+```json
+{
+  "name": "my-board",
+  "label": "My board",
+  "icon": "📋",
+  "tab": { "path": "/my-board" },
+  "entry": "index.js"
+}
+```
+
+The server exposes:
+
+- `GET /api/dashboard/plugins` — manifest list
+- `GET /dashboard-plugins/{name}/{path}` — static assets
+
+Plugins register views in `index.js`:
+
+```javascript
+window.aiui.registerView('my-board', async (container) => {
+  window.aiui.sdk.createBoard(container, {
+    fetch: async () => ({ columns: [...] }),
+  });
+});
+```
+
+Sample: [`sample-board`](../../src/praisonaiui/templates/frontend/dashboard-plugins/sample-board/).
+
+## Agent plugins vs dashboard plugins
+
+| System | Location | Purpose |
+|--------|----------|---------|
+| Agent plugins | `~/.praisonai/plugins/` | Python agent extensions |
+| Dashboard plugins | `~/.praisonai/dashboard-plugins/` | JS UI tabs |
+
+See [PraisonAI package integration](praisonai-package-integration.md) for backend wiring, jobs API, and deployment.
+
+## Granular control — opt-in / opt-out
+
+| What you control | How | Example |
+|------------------|-----|---------|
+| UI mode | `aiui.set_style(...)` | `"dashboard"`, `"chat"`, `"docs"` |
+| Sidebar pages | `aiui.set_pages([ids])` whitelist | `["chat", "sessions"]` |
+| Hide built-ins | YAML `pages.disabled: [...]` | Blacklist in server |
+| Sidebar on/off | `set_dashboard(sidebar=False)` | Chat-only full width |
+| Page title bar | `set_dashboard(page_header=False)` | Cleaner surface |
+| Optional modules | `set_dashboard(modules=[...])` | `["jobs"]` only |
+| Third-party tabs | Install chosen `dashboard-plugins/` folders | Manifest per plugin |
+| Shell chrome | `registerSlot` | Header/footer widgets |
+| Look only | `set_theme`, `set_branding`, `set_custom_css` | White-label |
+| Replace one page | `registerView(pageId, ...)` | Override built-in |
+| Board UI | `aiui.board()` or plugin | Not in default nav |
+
+**Note:** `@aiui.page()` custom pages are **not** filtered by `set_pages()` — only built-in dashboard pages are. Remove custom pages from code to hide them.
+
+### Example profiles
+
+```python
+# Chat-only
+aiui.set_style("dashboard")
+aiui.set_pages(["chat"])
+aiui.set_dashboard(sidebar=False, page_header=False)
+
+# Ops console — no chat
+aiui.set_pages(["sessions", "agents", "logs", "config", "usage", "approvals"])
+```
+
+```yaml
+style: dashboard
+pages:
+  enabled: [chat, agents, memory, sessions]
+dashboard:
+  sidebar: true
+  pageHeader: true
+  modules: [jobs]
+  plugin_dirs: [/opt/my-agent/plugins]
+```
+
+CLI: `aiui pages ids` lists built-in page ids for whitelists.
+
+## DRY rules for contributors
+
+1. Add new layout types in **`ui.py`** and one `case` in **`dashboard.js`**.
+2. Page-specific UI belongs in **`plugins/views/*.js`**, delegating to shared modules (`jobs.js`, etc.) via thin wrappers.
+3. Reuse **`_helpers.js`** (`pageToolbar`, `filterChips`, `searchInput`, `modalShell`, `toast`).
+4. Boards compose **`card`** / **`columns`** — do not duplicate card markup in plugins.

+# Backend Integration Contract
+
+PraisonAIUI supports a four-layer integration model so standalone mode and SDK-integrated mode can share the same feature APIs.
+
+## Four Layers
+
+1. **Feature API layer**  
+   Endpoints live in feature modules and expose stable HTTP/CLI behaviour.
+2. **Feature manager layer**  
+   Each feature manager keeps local fallback logic for standalone operation.
+3. **Backend factory layer**  
+   `praisonaiui.backends` provides optional injected factories (`get_workflow_runner()`, `get_hooks_lister()`, `get_usage_query()`, etc.).
+4. **SDK/runtime layer**  
+   PraisonAI or praisonaiagents implementations are used when injected or importable.
+
+## Injection Contract
+
+- Injected backends are optional and must be callable.
+- Features must keep local fallbacks when injected backends are absent or fail.
+- Backend call signatures should remain minimal and dict/list based.
+- Integration should not introduce hard imports in feature modules when a fallback already exists.
+
+## Operational Rule
+
+When integrated, wrappers should inject backend callables at startup; when standalone, features should run without any backend injection.

+# Image Preview in Chat
+
+Protocol-driven inline media for agent-generated images (and other element types) during chat streaming. Any backend that implements `BaseProvider` can emit images without PraisonAI-specific code in chat or the frontend.
+
+## Problem This Solves
+
+Before this feature, PraisonAIUI could **render** images (`Message.add_image`, `ElementRenderer`) but the **wire protocol dropped media** during agent runs. ImageAgent / tool results appeared as JSON in the tool-call panel instead of inline `<img>` previews.
+
+## Architecture
+
+Modular layers — same pattern as [A2UI surfaces](./agent-ui-host.md):
+
+```mermaid
+sequenceDiagram
+    participant Backend as Provider_or_Tool
+    participant Detect as media_utils.py
+    participant Protocol as RunEvent_MESSAGE_ELEMENT
+    participant Chat as chat.py
+    participant UI as chat.js_React
+
+    Backend->>Detect: tool result or callback payload
+    Detect->>Protocol: normalised element dict
+    Protocol->>Chat: broadcast message_element
+    Chat->>UI: WebSocket / SSE frame
+    UI->>UI: appendMediaElement / ElementRenderer
+    Chat->>Chat: persist elements in session history
+```
+
+### Layer responsibilities
+
+| Layer | Module | Backend-agnostic? |
+|-------|--------|-------------------|
+| **Detection** | [`media_utils.py`](../../src/praisonaiui/media_utils.py) | Yes — normalises OpenAI, URL, b64, element dicts |
+| **Protocol** | [`provider.py`](../../src/praisonaiui/provider.py) — `RunEventType.MESSAGE_ELEMENT` | Yes |
+| **Adapter** | [`providers/__init__.py`](../../src/praisonaiui/providers/__init__.py) — PraisonAI bridge only | No — maps SDK/callback queue → protocol |
+| **Transport** | [`chat.py`](../../src/praisonaiui/features/chat.py) — broadcast + persist | Yes |
+| **Storage** | [`attachments.py`](../../src/praisonaiui/features/attachments.py) — `GET /api/chat/media/{id}` | Yes — reuses attachment store for b64 |
+| **UI** | [`chat.js`](../../src/praisonaiui/templates/frontend/plugins/views/chat.js), [`ElementRenderer`](../../src/frontend/src/chat/MultimediaElements.tsx) | Yes — renders `{type, url, alt}` |
+
+Detection and UI do **not** import PraisonAI. Only the provider adapter knows ImageAgent / OpenAI `{data: [{url}]}` shapes.
+
+## Wire protocol
+
+### Event type
+
+```
+type: "message_element"
+element: { "type": "image", "url": "...", "alt": "..." }
+session_id: "..."
+run_id: "..."
+```
+
+Defined in Python as `RunEventType.MESSAGE_ELEMENT` and mirrored in [`types.ts`](../../src/frontend/src/types.ts).
+
+### Helper (any provider)
+
+```python
+from praisonaiui.provider import BaseProvider, RunEvent, RunEventType
+
+yield BaseProvider.message_element_event({
+    "type": "image",
+    "url": "https://example.com/out.png",
+    "alt": "Generated image",
+})
+```
+
+Element shape reuses the existing [message element schema](./message-elements.md) (`image`, `pdf`, `video`, `audio`, `file`, `code`).
+
+## Data flow paths
+
+### 1. Custom provider (swappable backend)
+
+```python
+import praisonaiui as aiui
+from praisonaiui.provider import BaseProvider, RunEvent, RunEventType
+
+class MyImageProvider(BaseProvider):
+    async def run(self, message, *, session_id=None, agent_name=None, **kw):
+        yield RunEvent(type=RunEventType.RUN_STARTED)
+        # Call any image API here (OpenAI, Stability, local, etc.)
+        yield BaseProvider.message_element_event({
+            "type": "image",
+            "url": image_url,
+            "alt": "Generated image",
+        })
+        yield RunEvent(type=RunEventType.RUN_COMPLETED, content="Here is your image.")
+
+aiui.set_provider(MyImageProvider())
+```
+
+Example app: [`examples/python/30-image-preview/app.py`](../../examples/python/30-image-preview/app.py).
+
+### 2. Callback handler (`@aiui.reply`)
+
+```python
+import praisonaiui as aiui
+from praisonaiui import Message
+
+@aiui.reply
+async def on_message(msg):
+    m = Message(content="Here is your image:")
+    m.add_image("https://example.com/chart.png", alt="Chart")
+    await m.send()
+```
+
+`PraisonAIProvider` maps queue events (`image`, `message` + `elements`) → `MESSAGE_ELEMENT`.
+
+### 3. Tool results (automatic detection)
+
+When a tool completes, `tool_completed_extra()` in [`a2ui_utils.py`](../../src/praisonaiui/a2ui_utils.py) calls `build_media_extra()` from `media_utils`. Supported shapes:
+
+| Input shape | Example |
+|-------------|---------|
+| OpenAI / ImageAgent | `{"data": [{"url": "...", "b64_json": "...", "revised_prompt": "..."}]}` |
+| Explicit element | `{"type": "image", "url": "..."}` |
+| Plain URL string | `"https://cdn.example.com/out.png"` |
+| Data URL | `"data:image/png;base64,..."` |
+| Nested elements | `{"elements": [{"type": "video", "url": "..."}]}` |
+
+`chat.py` broadcasts `message_element` for each detected element and attaches `elements` to the persisted assistant message.
+
+### 4. ImageAgent direct mode
+
+If the registered agent's `chat()` returns an OpenAI-shaped dict, `PraisonAIProvider._run_direct_mode` runs `extract_media_elements()` and emits `MESSAGE_ELEMENT` events before `RUN_COMPLETED`.
+
+## Base64 storage
+
+Large `b64_json` payloads are **not** stored inline in message history. They are decoded and saved via `AttachmentManager`, then served at:
+
+```
+GET /api/chat/media/{attachment_id}
+```
+
+If storage fails, the system falls back to a `data:image/png;base64,...` URL.
+
+## Frontend rendering
+
+| Surface | Handler |
+|---------|---------|
+| Dashboard chat (template) | `chat.js` — `case 'message_element': appendMediaElement()` |
+| React chat | `streamingStore.ts` — `pendingElements` + `ElementRenderer` |
+| Tool call panel | Thumbnail from `toolCall.elements` when expanded |
+| Session reload | `elements` on messages from `/api/chat/history` and `/sessions/{id}/runs` |
+
+See also [Message Elements](./message-elements.md) for element properties and display modes.
+
+## Deduplication
+
+`_collect_element()` in `chat.py` dedupes by URL so the same image is not stored twice when both a `MESSAGE_ELEMENT` event and a tool completion carry the same URL.
+
+## Out of scope
+
+- **REST image generation** (`POST /v1/images/generations`) — separate OpenAI-compat endpoint; not wired into chat streaming
+- **Canvas / A2UI surfaces** — separate feature for agent-driven UI catalogs
+- **Auto-registering ImageAgent** — agents are configured explicitly by the user
+
+## Tests
+
+```bash
+pytest tests/unit/test_media_utils.py \
+       tests/integration/test_chat_image_preview.py -v -o addopts=
+```
+
+Coverage includes: detection normalisation, b64 fallback, provider callback bridge, `_run_and_broadcast` persistence, media serve route, ImageAgent dict responses, URL dedup.

+# PraisonAI package integration
+
+How **PraisonAIUI** (`aiui`) connects to **`praisonai-package`** — the agent runtime, gateway, and CLI. For generic UI hosting see [Agent UI host](agent-ui-host.md).
+
+## Division of labour
+
+| Layer | Repo | Role |
+|-------|------|------|
+| Agent runtime | `praisonai-agents` | `Agent`, tools, memory, streaming |
+| Gateway, jobs, CLI | `praisonai` | WebSocket `/ws`, `/api/v1/runs`, `praisonai claw` |
+| Dashboard UI | **PraisonAIUI** | `dashboard.js`, `@aiui.page`, layout protocol |
+| Work tracking | `praisonai-platform` | Issues API (optional board data source) |
+
+Canonical app: `praisonai-package` → `src/praisonai/praisonai/claw/default_app.py`.
+
+## Deployment shapes
+
+### 1. Single process — `praisonai claw` (recommended)
+
+```bash
+praisonai claw   # → aiui run claw/default_app.py, default :8082
+```
+
+```text
+Browser → create_app() (same process)
+        → PraisonAISessionDataStore (sessions)
+        → PraisonAIProvider (@aiui.reply / agents)
+        → Built-in dashboard views
+```
+
+Use when: local dev, full dashboard, agents registered in Python.
+
+### 2. Unified — `AIUIGateway`
+
+```python
+from praisonaiui.integration import AIUIGateway
+gateway = AIUIGateway(port=8080)
+gateway.register_agent(agent)
+await gateway.start()   # create_app() + WebSocket /ws
+```
+
+Use when: you need **WebSocket gateway protocol** and dashboard on **one port**.
+
+### 3. Split — gateway + UI
+
+| Service | Default port | Endpoints |
+|---------|--------------|-----------|
+| `praisonai gateway start` | 8765 | `ws://…/ws`, `/health`, `/info` |
+| `praisonai claw` or `aiui run` | 8082 | Dashboard, `/run` SSE, `/api/*` |
+
+Use when: gateway runs headless; UI is a separate process. Point chat at gateway via provider config or run `AIUIGateway` instead.
+
+## Wiring checklist
+
+```python
+import praisonaiui as aiui
+from praisonai.ui._aiui_datastore import PraisonAISessionDataStore
+
+aiui.set_datastore(PraisonAISessionDataStore())
+aiui.set_style("dashboard")
+aiui.set_pages(["chat", "agents", "sessions", "config"])
+aiui.set_dashboard(modules=["jobs"], sidebar=True, page_header=True)
+
+# Optional: point jobs UI at package jobs server paths
+aiui.set_jobs_api(api_base="/api/v1/runs", backend="praisonai")
+```
+
+Or via host bootstrap:
+
+```python
+from praisonai.integration.host_app import configure_host, create_host_app
+
+configure_host(pages=[...], modules=["jobs"], agents=[...])
+app = create_host_app()
+```
+
+## API surface
+
+### Chat and agents (dashboard)
+
+| Endpoint | Purpose |
+|----------|---------|
+| `POST /run` | Stream agent run (SSE) |
+| `GET /sessions`, `POST /sessions` | Session CRUD |
+| `GET /agents`, `/api/agents/definitions` | Agent list / CRUD |
+| `GET /api/health` | Sidebar health slot |
+
+### Async jobs — two paths
+
+| Backend | Base path | When |
+|---------|-----------|------|
+| **aiui** `JobsFeature` | `/api/jobs` | Default; in-process job store |
+| **praisonai** jobs server | `/api/v1/runs` | Standalone `praisonai jobs` / FastAPI router |
+
+Configure the dashboard jobs view:
+
+```python
+aiui.set_jobs_api(api_base="/api/jobs", backend="aiui")       # default
+aiui.set_jobs_api(api_base="/api/v1/runs", backend="praisonai")
+```
+
+`/ui-config.json` exposes `jobs: { apiBase, backend }` for `jobs.js`.
+
+**Response shapes:** both return `{ jobs, total }`. Praison uses `job_id`; aiui uses `id`. The jobs view normalises either field.
+
+| Action | aiui | praisonai |
+|--------|------|-----------|
+| List | `GET /api/jobs` | `GET /api/v1/runs` |
+| Detail | `GET /api/jobs/{id}` | `GET /api/v1/runs/{id}` |
+| Cancel | `POST /api/jobs/{id}/cancel` | `POST /api/v1/runs/{id}/cancel` |
+| Stream | `GET /api/jobs/{id}/stream` | `GET /api/v1/runs/{id}/stream` |
+| Delete | `DELETE /api/jobs/{id}` | Not on package router |
+
+**Split jobs server (optional):** proxy aiui `/api/jobs/*` to an external jobs host:
+
+```python
+aiui.set_jobs_proxy("http://127.0.0.1:9000")  # forwards to /api/v1/runs/*
+aiui.set_jobs_api(api_base="/api/jobs", backend="aiui")
+```
+
+Use when the dashboard and jobs server run on different ports. Prefer `set_jobs_backend("praisonai")` when the browser can call `/api/v1/runs` on the same origin.
+
+### REST invoke (automation)
+
+| Path | Use |
+|------|-----|
+| `POST /api/v1/agents/{id}/invoke` | Sync invoke (n8n, scripts) — **package** `agent_invoke.py` |
+| `POST /run` | Streaming chat — **dashboard** chat page |
+
+Same agents if registered on both surfaces; different protocols.
+
+### Discovery (package serve)
+
+| Endpoint | Purpose |
+|----------|---------|
+| `GET /__praisonai__/discovery` | Serve-mode capability discovery |
+| `GET /health`, `GET /info` | Gateway liveness and metadata |
+| `GET /api/gateway/status` | aiui gateway feature status |
+
+See **Feature Explorer** page in dashboard for live probes.
+
+## Parallel UI protocols (not dashboard replacements)
+
+Under `praisonaiagents/ui/`:
+
+| Protocol | Purpose |
+|----------|---------|
+| **A2A** | Agent cards, `/.well-known/agent.json`, external agent hosts |
+| **AG-UI** | CopilotKit-style event stream (`POST /agui`) |
+| **A2UI** | Declarative surfaces in chat/canvas |
+
+Dashboard shell remains the ops console for `praisonai claw`. Use A2A/AG-UI/A2UI when embedding in other products.
+
+## Two plugin systems
+
+| System | Location | Purpose |
+|--------|----------|---------|
+| **Agent plugins** | `~/.praisonai/plugins/` | Python agent extensions (`praisonaiagents.plugins`) |
+| **Dashboard plugins** | `~/.praisonai/dashboard-plugins/` | JS tabs + `manifest.json` for aiui shell |
+
+Do not mix folders. Agent plugins extend runtime; dashboard plugins extend UI tabs only.
+
+## Optional modules
+
+```python
+aiui.set_dashboard(modules=["jobs", "auth", "api"])
+```
+
+Loads `jobs.js`, `auth.js`, `api.js` into the plugin chain and maps them in `BUILTIN_VIEWS`. Enable only what your deployment exposes.
+
+## Board / work tracking
+
+Neither repo ships Hermes-style Kanban. Options:
+
+1. **`aiui.board()`** — columns from `@aiui.page` handler (jobs by status, custom data).
+2. **`praisonai-platform` issues** — map issue `status` → board columns (see `examples/python/platform-board/`). Set `PRAISONAI_PLATFORM_URL` and `PRAISONAI_PLATFORM_WORKSPACE_ID` (default workspace `default`); issues are fetched from `GET /api/v1/workspaces/{workspace_id}/issues`.
+3. **`dashboard-plugins`** — rich JS via `registerView` + `sdk.createBoard`.
+
+Advanced board UX (drag-drop, WebSocket sync) is **deferred** — use polling via `sdk.createBoard({ pollMs })` or a custom plugin.
+
+## Smoke checklist
+
+After `praisonai claw` or `aiui run` with package bridges:
+
+- [ ] `GET /api/health` → sidebar footer shows healthy
+- [ ] Chat page sends message, streams reply
+- [ ] Sessions page lists `~/.praisonai/sessions/` data
+- [ ] Agents page CRUD (if agents registered)
+- [ ] Jobs page (if `modules` includes `jobs` and jobs API configured)
+- [ ] Explorer probes `/health`, `/ui-config.json`, `/api/dashboard/plugins`
+- [ ] Auth/API pages (if `modules` includes `auth` / `api`)

+# Standalone vs Integrated
+
+This page summarises the expected install and runtime shape for PraisonAIUI in both modes.
+
+## Install Matrix
+
+| Mode | Package install | Runtime dependency | Behaviour |
+| --- | --- | --- | --- |
+| Standalone UI | `pip install praisonaiui` | Optional SDK packages absent | Uses built-in local managers and fallbacks |
+| Integrated (PraisonAI) | `pip install praisonaiui praisonai praisonaiagents` | SDK and wrapper available | Uses injected backends and SDK-aware managers |
+
+## Backend injection (integrated mode)
+
+When hosted via `praisonai.integration.host_app.configure_host()`, the wrapper calls `praisonaiui.backends.set_backend()` for:
+
+| Backend key | Feature area |
+| --- | --- |
+| `hooks` | Hooks dashboard |
+| `workflows` | Workflow runs |
+| `usage_query` / `usage_sink` | Usage analytics |
+| `approvals_pending` / `approvals_policies` | HITL approvals |
+| `jobs_store` / `jobs_executor` | Async jobs (optional) |
+| `channel_bot` | Channel bots (optional) |
+| `tool_resolver` | Agent tool name resolution (optional) |
+
+Detect integrated mode in code: `praisonaiui.backends.is_integrated_mode()`.
+
+## Documented SDK gaps (local fallback)
+
+These features work standalone with in-memory stores. Health responses include `sdk_gap: true`:
+
+| Feature | Gap | Standalone behaviour |
+| --- | --- | --- |
+| **nodes** | No cluster API in praisonaiagents | In-memory node registry |
+| **auth** | No SDK auth module | In-memory API keys / sessions |
+| **channels** | Bot runtime via praisonai wrapper | In-memory channel registry; bots need `praisonai[bot]` |
+| **jobs** | Mock success only when standalone and agent missing | Integrated mode fails job instead of fake success |
+| **realtime** | WebRTC needs `OPENAI_API_KEY` | Mock stream standalone; degraded error when integrated without key |
+| **media / code** | SDK paths optional | `status: simulated` standalone; `status: degraded` integrated on failure |
+
+View gaps in the dashboard sidebar footer (`GET /api/health` → `sdk_gaps` array).
+
+## Practical Differences
+
+- **Session/data handling**: standalone uses UI datastore fallback; integrated aligns with SDK-backed stores.
+- **Feature backends**: standalone keeps in-memory/mock behaviour; integrated routes through injected factories.
+- **Lifecycle hooks**: integrated mode can subscribe to SDK hooks (handoff, MCP lifecycle, tracing/eval stores).
+
+## Recommendation
+
+Use standalone mode for local UI-only workflows. Use integrated mode when you need shared runtime state with PraisonAI agents, tools, tracing, approvals, and schedules.
+
+See also [backend-integration.md](backend-integration.md) and [praisonai-package-integration.md](praisonai-package-integration.md).

+# Video Studio
+
+The Video Studio integrates [PraisonAI Video](https://github.com/MervinPraison/praisonai-video) as an external Node render engine. PraisonAIUI provides the dashboard shell, project files, YAML editor, job UX, and HTTP proxying. The video engine handles parse, compile, lint, and MP4 export. **Agents live in PraisonAI (Chat + tools), not inside the renderer.**
+
+## Prerequisites
+
+1. Install PraisonAI Video CLI (`praisonai-video`) or run from the monorepo.
+2. Start the engine sidecar (recommended):
+
+```bash
+praisonai-video serve --port 3921
+```
+
+3. Run the example app:
+
+```bash
+aiui run examples/python/video-studio/app.py
+```
+
+Open the **Video** tab, create a project, edit `scene.yaml`, and use Lint / Render.
+
+For **Chat** to edit scenes, install `praisonaiagents` and set `OPENAI_API_KEY`. Optional: `VIDEO_STUDIO_PROJECT_ID` to target a specific project.
+
+## Configuration
+
+| Variable | Default | Purpose |
+|----------|---------|---------|
+| `VIDEO_ENGINE_URL` | `http://127.0.0.1:3921` | HTTP API base URL |
+| `VIDEO_ENGINE_TOKEN` | (none) | Optional Bearer token forwarded to the engine |
+| `PRAISONAI_PROJECTS_DIR` | `~/.praisonai/projects` | On-disk project roots |
+| `PRAISONAI_VIDEO_CLI` | (auto-detect) | Path to `praisonai-video` or `dist/cli.js` for subprocess fallback |
+| `VIDEO_STUDIO_PROJECT_ID` | (auto) | Active project for agent tools when not passed explicitly |
+| `PRAISONAI_MODEL` | `gpt-4o-mini` | LLM for Video Editor agent in the example app |
+
+Python API:
+
+```python
+from praisonaiui.video_config import set_video_engine
+
+set_video_engine(url="http://127.0.0.1:3921", projects_dir="~/my-videos")
+```
+
+## Projects
+
+Each project is a directory containing:
+
+- `scene.yaml` — scene definition
+- `scene.visual-test.yaml` — optional visual regression spec
+- `.praisonai/project.json` — metadata
+- `exports/` — rendered MP4 artefacts
+
+## API routes
+
+All routes are under `/api/video/`:
+
+- `GET /health` — sidecar status
+- `POST /lint`, `POST /compile` — scene validation
+- `GET /preview-url`, `POST /preview/start` — preview iframe URL (CLI; dashboard preview hidden)
+- `POST /render` — async render job (`type: video_render`); optional `backend` (`playwright` | `remotion`) overrides `scene.yaml` `render.backend`
+- `GET /jobs/{id}` — job status and download URL
+- `GET|POST /projects` — list and create projects
+- `GET /projects/{id}/studio-refresh` — poll after agent tool updates (`refresh: true` once)
+
+When the HTTP sidecar is unavailable, lint and render fall back to subprocess calls to `praisonai-video`.
+
+## Dashboard plugin
+
+The UI lives in `dashboard-plugins/video-studio/` (built-in) or `~/.praisonai/dashboard-plugins/video-studio/` for overrides. It uses `window.aiui.sdk.fetchJSON`.
+
+**Frame-by-frame composition preview is hidden** in the dashboard (`SHOW_COMPOSITION_PREVIEW = false`) until serve preview + seek are reliable. Use **Render MP4** and the **Your video** player for output. Set the flag to `true` in `index.js` to re-enable the optional iframe scrubber.
+
+After agent tool writes, the editor reloads via `video-studio:refresh` (custom event) or polling `studio-refresh`.
+
+## Agent workflow (PraisonAI-first)
+
+1. Open **Chat** with the Video Editor agent (example app registers tools when `praisonaiagents` is installed).
+2. Agent calls `video_get_scene` / `video_update_scene` / `video_lint_scene` / `video_render_project` (same outcomes as UI buttons).
+3. Video Studio tab picks up changes automatically.
+
+Tools are defined in `praisonaiui/video_agent_tools.py`. For Cursor/Codex outside the UI, use the skill at `skills/praisonai-video/SKILL.md` in the PraisonAI Video repo.
+
+### Optional render backends
+
+Default is **Playwright** (no `render:` block in `scene.yaml`). Use Remotion only when required:
+
+```yaml
+render:
+  backend: remotion   # needs Remotion licence + remotion-root export; lint will error on default YAML export
+```
+
+`video_render_project(backend="playwright")` overrides YAML for one agent run. Hyperframes is deferred.
+
+## CLI parity
+
+The text box edits the same `scene.yaml` the CLI uses. Equivalent commands (from the video repo):
+
+```bash
+praisonai-video project create "My video"
+praisonai-video project lint <project-id>
+praisonai-video project preview <project-id>
+praisonai-video project test <project-id>
+praisonai-video project render <project-id>
+praisonai-video project reset <project-id>
+```
+
+Lint editor text without saving: `praisonai-video lint --stdin < scene.yaml`
+
+See `docs/integrations/praisonaiui.md` in the PraisonAI Video repo for the full mapping table.

+# shadcn Dependencies Installation Demo
+
+This example demonstrates the automatic installation of shadcn UI components at build time using the `dependencies.shadcn` configuration.
+
+## How it works
+
+When you build this project, PraisonAIUI will automatically download and install the following 22 shadcn components:
+
+- **UI Components**: card, button, input, label, avatar, badge, progress, separator, switch, checkbox, radio-group, select, slider, tabs, accordion, dialog, dropdown-menu, popover, tooltip, table
+- **Advanced Components**: calendar, chart
+
+## What gets installed
+
+The components are downloaded from the shadcn/ui registry and installed in your project's components directory. They become available for use in your custom components and templates.
+
+## Note
+
+This example demonstrates dependency installation only. For actual component showcases with live demos, see the shadcn documentation at [ui.shadcn.com](https://ui.shadcn.com).
