# Admin Frontend Context

This document describes the current real structure of the console frontend. The goal is to help future page development, table refactoring, layout governance, and state consolidation quickly find the right entry points.

Related references:

- [Project Rules](/home/ray/dev/linkong/planet/rules.md)
- [Frontend Layout Guidelines](/home/ray/dev/linkong/planet/docs/technical/en/frontend-layout-guidelines.md)

## Current Goal

The console frontend is a backend workbench, not a display-style dashboard. Current constraints:

- Pages default to a single-screen work area
- Primary interaction happens through in-module scrolling, not relying on the whole page growing infinitely
- Lists, tables, and analysis pages prioritize keeping the main work area visible
- Common layout, scrollbar, and table scroll behavior should be reused across pages

## Current Route Entry Points

Main entry point:

- [App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx)

Current admin-related routes:

- `/admin`
- `/users`
- `/datasources`
- `/data`
- `/alerts/system`
- `/alerts/bgp`
- `/alerts/situational`
- `/bgp`
- `/ai`
- `/settings`

`/earth` is a standalone display page and is not part of the console shell.

## Current Page Shell

The console shared shell is at:

- [AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx)

Responsibilities:

- Left-side navigation
- Collapse and expand
- Current account / version information
- Content area height closure
- Site-wide unified sidebar scrollbar

Current structure:

```tsx
<Layout className="dashboard-layout">
  <Sider className="dashboard-sider">...</Sider>
  <Layout>
    <Content className="dashboard-content">
      <div className="dashboard-content-inner">{children}</div>
    </Content>
  </Layout>
</Layout>
```

Future console pages should adapt to this shell rather than redefining full-page height semantics.

## Current Shared Components

### 1. `Scrollbar`

File:

- [Scrollbar.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/Scrollbar.tsx)

Purpose:

- Ordinary content containers like the console sidebar
- Internally manages visibility, thumb size, drag, and dual-axis overflow detection

Current constraint:

- The scrollbar must be a floating overlay that does not participate in layout
- Should leave no visible trace when there is no overflow
- Real scrolling is still handled by the native container; only the visible layer and interaction layer are replaced

### 2. `ScrollbarOverlay`

File:

- [ScrollbarOverlay.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/ScrollbarOverlay.tsx)

Purpose:

- Areas like Ant Table that already have an internal scroll container
- Does not take over scroll semantics; only adds a new scrollbar visible layer

Current usage:

- Data sources
- Collected data
- User management
- Settings page
- Alerts page
- BGP page

### 3. `TableScrollRegion`

File:

- [TableScrollRegion.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/TableScrollRegion.tsx)

Purpose:

- Provides a unified wrapper for table scroll areas
- New table pages should reuse this rather than repeating the "table area + overlay scrollbar" boilerplate

### 4. `SegmentedControl`

Files:

- [SegmentedControl.tsx](/home/ray/dev/linkong/planet/frontend/src/components/SegmentedControl/SegmentedControl.tsx)
- [SegmentedControl.css](/home/ray/dev/linkong/planet/frontend/src/components/SegmentedControl/SegmentedControl.css)

Purpose:

- Segmented controls for language, theme, mode, or other 2 to 3 option settings
- Settings that need the shared animated slider, active state, and compact button layout
- The `/docs` footer language switcher and theme switcher already reuse it

Interface semantics:

- `options`: each option contains `value` and `label`, with optional `icon` and `title`
- `value`: current active value
- `onChange`: called when the selected option changes
- `ariaLabel`: accessible name for the control
- `className`: page-level hook for size or local style overrides

Current constraints:

- The component owns slider count, position, and spring-like transition
- Feature pages should only pass options and state, not recreate private slider DOM
- Prefer CSS variable overrides for colors instead of hard-coding theme colors in feature components
- Best for a small set of mutually exclusive choices; do not use it as a long list, navigation menu, or select replacement

### 5. `MarkdownRenderer`

File:

- [MarkdownRenderer.tsx](/home/ray/dev/linkong/planet/frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx)

Purpose:

- Renders Markdown content for `/docs`
- Supports headings, lists, blockquotes, code blocks, tables, and basic inline formatting
- Code blocks and tables reuse `Scrollbar` so horizontal content does not blow out the docs page
- Docs content is returned by backend `/api/v1/docs/...` endpoints according to Gatekeeper permissions; the frontend only renders content visible to the current user

Current constraints:

- It is not a full GitHub Markdown engine; it only covers the syntax currently needed by project docs
- Internal document links should be converted to `/docs/:slug` through `transformLink`
- Heading anchors are injected through `getHeadingId`, keeping route state outside the renderer

### 6. `ConnectionTestInput`

File:

- [ConnectionTestInput.tsx](/home/ray/dev/linkong/planet/frontend/src/components/ConnectionTestInput/ConnectionTestInput.tsx)

Purpose:

- Console form fields that combine an endpoint/Base URL value with a connection check
- Connection-test entry points for AI Provider and WebSearch
- Future collector configuration fields should reuse it when the test action belongs inside the input

Current constraints:

- The input suffix shows a single plug/connector icon, not an adjacent text button
- Disabled integrations must grey out both the input and its connection-test action
- The component only combines the input and action; callers still own form state, loading, disabled state, and the request itself

### 7. `TableActions`

File:

- [TableActions.tsx](/home/ray/dev/linkong/planet/frontend/src/components/TableActions/TableActions.tsx)

Purpose:

- Shared action entry for table operation columns
- Shows inline actions when expanded
- Uses a more-actions dropdown when collapsed

Companion export:

- `actionCellProps`: for action-column `onCell`, preventing action buttons from being ellipsized or wrapped

## Current State Sources

### 1. Auth State

File:

- [auth.ts](/home/ray/dev/linkong/planet/frontend/src/stores/auth.ts)

Responsibilities:

- Token
- Current user
- Gatekeeper groups
- Login / logout

`App.tsx` uses it to decide whether to redirect to the login page. `/docs` remains a public route, but the backend decides the visible catalog and content from the token; anonymous visitors only receive public docs.

### 2. AI

File:

- [AISettings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/AISettings/AISettings.tsx)

Responsibilities:

- `/ai` now owns LLM Provider, AI Tool configuration, and the testbench instead of nesting them under `/settings`
- The `模型供应商` tab manages default provider, model, base URL, provider key, local `aiprovider` proxy, and connection test; provider and model fields use editable comboboxes so users can manually enter new providers/models if the models.dev catalog stops updating
- The `工具` tab first selects a tool from a dropdown menu, then renders that tool's configuration; it currently includes WebSearch and OCR
- WebSearch configuration includes provider, search key, base URL, timeout, result count, and advanced provider options
- OCR configuration includes provider, Base URL, API key, model/engine, languages, timeout, file-size limit, and output format
- The `测试台` tab embeds the former Playground real session, preset prompts, and AI Provider status debugging
- The page reuses the Settings single-screen tabs, panel card, and internal scrolling style
- AI Provider and WebSearch connection tests use `ConnectionTestInput`, with the connector icon fixed at the end of the Base URL input; when WebSearch is disabled, every configuration field and the test entry point are greyed out except the switch

Legacy `/settings?tab=ai` should redirect to `/ai?tab=providers`.
Legacy `/playground` should redirect to `/ai?tab=playground`.

### 3. Business Data Gateway

AI / situational awareness related services are currently in:

- [http-gateway.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/http-gateway.ts)
- [port.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/port.ts)
- [types.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/types.ts)

Constraints:

- Pages must not scatter URL construction directly
- Define boundaries through port/types first
- Then implement via http/mock gateway

## Current Page Layer Recommendations

### 1. Dashboard and Summary Pages

Example:

- [Dashboard.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Dashboard/Dashboard.tsx)

Priority goals:

- Stable header
- Summary cards compact first
- Main work area occupies primary height

### 2. Table Pages

Examples:

- [DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx)
- [DataList.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataList/DataList.tsx)
- [Users.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Users/Users.tsx)
- [Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx)

Constraints:

- Prefer internal scrolling
- Do not let tables blow out the full page
- New table areas should reuse `TableScrollRegion` / `ScrollbarOverlay`

### 3. Complex Workspace Pages

Examples:

- [BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx)
- [Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx)

Constraints:

- Tab content must not share the same height logic
- Table tabs, Markdown tabs, and config tabs each need their own scroll responsibility
- AI result areas and long text areas should maintain a minimum readable height

## Current Layout Constraints

These principles have been repeatedly validated in the project:

1. Parent container height chain must close
2. `min-height: 0` must not be omitted
3. Overflow responsibility must be explicit
4. Do not use `overflow: hidden` to mask structural issues
5. Do not compress the main work area to make summary cards show completely
6. Custom scrollbars must be floating overlays; they must not squeeze content width

For detailed experience, see:

- [Frontend Layout Guidelines](/home/ray/dev/linkong/planet/docs/technical/en/frontend-layout-guidelines.md)

## Recommended Change Approach

For future console page changes:

1. Confirm whether the page is a summary page, table page, or complex workspace
2. Integrate into the existing shell and scroll semantics first
3. Reuse shared scroll components
4. Handle visual and detail interactions last

Do not write local CSS patches first, then retrofit the structure.

## Current Clear Boundary

The console frontend and the Earth frontend are not the same system:

- Console frontend: React + Ant Design workbench
- Earth frontend: independent native HUD system under `public/earth`

Therefore:

- Do not move Earth's HUD / animations / state machine directly into the console
- Do not force the console's table / scroll strategy onto the Earth HUD

For Earth-related structure, see:
