feat: add source badge to LogViewer entries

LogEntry now accepts an optional `source` field. When present, a small
badge (container/app/agent) renders between the level and message columns.
Backward compatible — entries without source render as before.

+# GitNexus — Code Intelligence
+
+This project is indexed by GitNexus as **design-system** (1461 symbols, 2336 relationships, 23 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.
+
+> If any GitNexus tool warns the index is stale, run `npx gitnexus analyze` in terminal first.
+
+## Always Do
+
+- **MUST run impact analysis before editing any symbol.** Before modifying a function, class, or method, run `gitnexus_impact({target: "symbolName", direction: "upstream"})` and report the blast radius (direct callers, affected processes, risk level) to the user.
+- **MUST run `gitnexus_detect_changes()` before committing** to verify your changes only affect expected symbols and execution flows.
+- **MUST warn the user** if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
+- When exploring unfamiliar code, use `gitnexus_query({query: "concept"})` to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
+- When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use `gitnexus_context({name: "symbolName"})`.
+
+## When Debugging
+
+1. `gitnexus_query({query: "<error or symptom>"})` — find execution flows related to the issue
+2. `gitnexus_context({name: "<suspect function>"})` — see all callers, callees, and process participation
+3. `READ gitnexus://repo/design-system/process/{processName}` — trace the full execution flow step by step
+4. For regressions: `gitnexus_detect_changes({scope: "compare", base_ref: "main"})` — see what your branch changed
+
+## When Refactoring
+
+- **Renaming**: MUST use `gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})` first. Review the preview — graph edits are safe, text_search edits need manual review. Then run with `dry_run: false`.
+- **Extracting/Splitting**: MUST run `gitnexus_context({name: "target"})` to see all incoming/outgoing refs, then `gitnexus_impact({target: "target", direction: "upstream"})` to find all external callers before moving code.
+- After any refactor: run `gitnexus_detect_changes({scope: "all"})` to verify only expected files changed.
+
+## Never Do
+
+- NEVER edit a function, class, or method without first running `gitnexus_impact` on it.
+- NEVER ignore HIGH or CRITICAL risk warnings from impact analysis.
+- NEVER rename symbols with find-and-replace — use `gitnexus_rename` which understands the call graph.
+- NEVER commit changes without running `gitnexus_detect_changes()` to check affected scope.
+
+## Tools Quick Reference
+
+| Tool | When to use | Command |
+|------|-------------|---------|
+| `query` | Find code by concept | `gitnexus_query({query: "auth validation"})` |
+| `context` | 360-degree view of one symbol | `gitnexus_context({name: "validateUser"})` |
+| `impact` | Blast radius before editing | `gitnexus_impact({target: "X", direction: "upstream"})` |
+| `detect_changes` | Pre-commit scope check | `gitnexus_detect_changes({scope: "staged"})` |
+| `rename` | Safe multi-file rename | `gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})` |
+| `cypher` | Custom graph queries | `gitnexus_cypher({query: "MATCH ..."})` |
+
+## Impact Risk Levels
+
+| Depth | Meaning | Action |
+|-------|---------|--------|
+| d=1 | WILL BREAK — direct callers/importers | MUST update these |
+| d=2 | LIKELY AFFECTED — indirect deps | Should test |
+| d=3 | MAY NEED TESTING — transitive | Test if critical path |
+
+## Resources
+
+| Resource | Use for |
+|----------|---------|
+| `gitnexus://repo/design-system/context` | Codebase overview, check index freshness |
+| `gitnexus://repo/design-system/clusters` | All functional areas |
+| `gitnexus://repo/design-system/processes` | All execution flows |
+| `gitnexus://repo/design-system/process/{name}` | Step-by-step execution trace |
+
+## Self-Check Before Finishing
+
+Before completing any code modification task, verify:
+1. `gitnexus_impact` was run for all modified symbols
+2. No HIGH/CRITICAL risk warnings were ignored
+3. `gitnexus_detect_changes()` confirms changes match expected scope
+4. All d=1 (WILL BREAK) dependents were updated
+
+## Keeping the Index Fresh
+
+After committing code changes, the GitNexus index becomes stale. Re-run analyze to update it:
+
+```bash
+npx gitnexus analyze
+```
+
+If the index previously included embeddings, preserve them by adding `--embeddings`:
+
+```bash
+npx gitnexus analyze --embeddings
+```
+
+To check whether embeddings exist, inspect `.gitnexus/meta.json` — the `stats.embeddings` field shows the count (0 means no embeddings). **Running analyze without `--embeddings` will delete any previously generated embeddings.**
+

 ## Charting Strategy
 
-The design system includes built-in **AreaChart**, **BarChart**, **LineChart**, and **Sparkline** components for standard use cases. For advanced chart types (treemap, radar, heatmap, pie, sankey, etc.), consuming apps should use **Recharts** directly with the design system's theme preset for visual consistency.
+The design system provides a **ThemedChart** wrapper component that applies consistent styling to Recharts charts. Recharts is bundled as a dependency — consumers do not need to install it separately.
 
-**Recharts is the app's dependency, not the design system's.** The design system only exports a theme config object.
+### Usage
-
-### Setup in consuming app
-
-```bash
-npm install recharts
-```

+# Recharts Migration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the design system's hand-rolled SVG chart components with a single `ThemedChart` wrapper around Recharts, using Recharts-native data format.
+
+**Architecture:** Add Recharts as a DS dependency. Create `ThemedChart` component that renders `ResponsiveContainer` + `ComposedChart` with pre-themed grid/axes/tooltip. Consumers compose Recharts elements (`<Line>`, `<Area>`, `<Bar>`, `<ReferenceLine>`) as children. Delete old `LineChart/`, `AreaChart/`, `BarChart/`, `_chart-utils.ts`. Migrate the server UI's `AgentInstance.tsx` to the new API.
+
+**Tech Stack:** React 19, Recharts, CSS Modules, Vitest

+
+### Task 4: Update Barrel Exports and Delete Old Charts
+
+**Files:**
+- Modify: `src/design-system/composites/index.ts`
+- Delete: `src/design-system/composites/LineChart/`
+- Delete: `src/design-system/composites/AreaChart/`
+- Delete: `src/design-system/composites/BarChart/`
+- Delete: `src/design-system/composites/_chart-utils.ts`
+
+- [ ] **Step 1: Update composites/index.ts**
+
+Remove these lines:
+```
+export { AreaChart } from './AreaChart/AreaChart'
+export { BarChart } from './BarChart/BarChart'
+export { LineChart } from './LineChart/LineChart'
+export { CHART_COLORS } from './_chart-utils'
+export type { ChartSeries, DataPoint } from './_chart-utils'
+```
+
+Add in their place:
+```tsx
+// Charts — ThemedChart wrapper + Recharts re-exports
+export { ThemedChart } from './ThemedChart/ThemedChart'
+export { CHART_COLORS, rechartsTheme } from '../utils/rechartsTheme'
+export {
+  Line, Area, Bar,
+  ReferenceLine, ReferenceArea,
+  Legend, Brush,
+} from 'recharts'
+```
+
+- [ ] **Step 2: Remove the rechartsTheme re-export from main index.ts**
+
+In `src/design-system/index.ts`, remove this line (it's now re-exported via composites):
+```
+export * from './utils/rechartsTheme'
+```
+
+Replace with a targeted export that avoids double-exporting `CHART_COLORS`:
+```tsx
+export { rechartsTheme } from './utils/rechartsTheme'
+```
+
+Wait — actually `composites/index.ts` already re-exports both `CHART_COLORS` and `rechartsTheme`. And `index.ts` does `export * from './composites'`. So the main `index.ts` line `export * from './utils/rechartsTheme'` would cause a duplicate export of both symbols. Remove it entirely:
+
+Delete this line from `src/design-system/index.ts`:
+```
+export * from './utils/rechartsTheme'
+```
+
+- [ ] **Step 3: Delete old chart directories and utilities**
+
+```bash
+rm -rf src/design-system/composites/LineChart
+rm -rf src/design-system/composites/AreaChart
+rm -rf src/design-system/composites/BarChart
+rm src/design-system/composites/_chart-utils.ts
+```
+
+- [ ] **Step 4: Verify lib build**
+
+```bash
+npm run build:lib
+```
+
+Expected: Build succeeds. The old components are gone, ThemedChart and Recharts re-exports are the new public API.
+
+- [ ] **Step 5: Run all tests**
+
+```bash
+npx vitest run
+```
+
+Expected: All tests pass. No test files existed for the deleted components.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add -A
+git commit -m "feat!: replace custom chart components with ThemedChart + Recharts
+
+BREAKING: LineChart, AreaChart, BarChart, ChartSeries, DataPoint removed.
+Use ThemedChart with Recharts children (Line, Area, Bar, etc.) instead."
+```
+
+---
+
+### Task 5: Update COMPONENT_GUIDE.md
+
+**Files:**
+- Modify: `COMPONENT_GUIDE.md`
+
+- [ ] **Step 1: Update the charting strategy section**
+
+Find the section starting with `## Charting Strategy` (around line 183) and replace through line 228 with:
+
+```markdown
+## Charting Strategy
+
+The design system provides a **ThemedChart** wrapper component that applies consistent styling to Recharts charts. Recharts is bundled as a dependency — consumers do not need to install it separately.
+
+### Usage
+
+```tsx
+import { ThemedChart, Line, Area, ReferenceLine, CHART_COLORS } from '@cameleer/design-system'
+
+const data = metrics.map(m => ({ time: m.timestamp, cpu: m.value * 100 }))
+
+<ThemedChart data={data} height={160} xDataKey="time" yLabel="%">
+  <Area dataKey="cpu" stroke={CHART_COLORS[0]} fill={CHART_COLORS[0]} fillOpacity={0.1} />
+  <ReferenceLine y={85} stroke="var(--error)" strokeDasharray="5 3" label="Alert" />
+</ThemedChart>
+```
+
+### ThemedChart Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `data` | `Record<string, any>[]` | required | Flat array of data objects |
+| `height` | `number` | `200` | Chart height in pixels |
+| `xDataKey` | `string` | `"time"` | Key for x-axis values |
+| `xType` | `'number' \| 'category'` | `"category"` | X-axis scale type |
+| `xTickFormatter` | `(value: any) => string` | — | Custom x-axis label formatter |
+| `yTickFormatter` | `(value: any) => string` | — | Custom y-axis label formatter |
+| `yLabel` | `string` | — | Y-axis label text |
+| `children` | `ReactNode` | required | Recharts elements (Line, Area, Bar, etc.) |
+| `className` | `string` | — | Container CSS class |
+
+### Available Recharts Re-exports
+
+`Line`, `Area`, `Bar`, `ReferenceLine`, `ReferenceArea`, `Legend`, `Brush`
+
+For chart types not covered (treemap, radar, pie, sankey), import from `recharts` directly and use `rechartsTheme` for consistent styling.
+
+### Theme Utilities
+
+| Export | Purpose |
+|--------|---------|
+| `CHART_COLORS` | Array of `var(--chart-1)` through `var(--chart-8)` |
+| `rechartsTheme` | Pre-configured prop objects for Recharts sub-components |
+```
+
+- [ ] **Step 2: Update the component index table**
+
+Find the rows for `AreaChart`, `BarChart`, `LineChart` in the component index table and replace all three with:
+
+```
+| ThemedChart | composite | Recharts wrapper with themed axes, grid, and tooltip |
+```
+
+- [ ] **Step 3: Update the decision tree**
+
+Find lines 57-60 (the chart decision tree entries):
+```
+- Time series → **LineChart**, **AreaChart**
+- Categorical comparison → **BarChart**
+```
+
+Replace with:
+```
+- Time series → **ThemedChart** with `<Line>` or `<Area>`
+- Categorical comparison → **ThemedChart** with `<Bar>`
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add COMPONENT_GUIDE.md
+git commit -m "docs: update COMPONENT_GUIDE for ThemedChart migration"
+```
+
+---
+
+### Task 6: Publish Design System
+
+**Files:**
+- Modify: `package.json` (version bump)
+
+- [ ] **Step 1: Bump version**
+
+In `package.json`, change `"version"` to `"0.1.47"`.
+
+- [ ] **Step 2: Build and verify**
+
+```bash
+npm run build:lib
+```
+
+- [ ] **Step 3: Commit and tag**
+
+```bash
+git add package.json
+git commit -m "chore: bump version to 0.1.47"
+git tag v0.1.47
+git push && git push --tags
+```
+
+- [ ] **Step 4: Wait for CI to publish**
+
+Wait for the Gitea CI pipeline to build and publish `@cameleer/design-system@0.1.47` to the npm registry. Verify with:
+
+```bash
+npm view @cameleer/design-system@0.1.47 version
+```
+
+---
+
+### Task 7: Migrate Server UI AgentInstance Charts
+
+**Files:**
+- Modify: `C:\Users\Hendrik\Documents\projects\cameleer3-server\ui\src\pages\AgentInstance\AgentInstance.tsx`
+- Modify: `C:\Users\Hendrik\Documents\projects\cameleer3-server\ui\package.json`
+
+- [ ] **Step 1: Update design system dependency**
+
+```bash
+cd C:\Users\Hendrik\Documents\projects\cameleer3-server\ui
+npm install @cameleer/design-system@0.1.47
+```
+
+- [ ] **Step 2: Update imports in AgentInstance.tsx**
+
+Replace the chart-related imports:
+
+Old:
+```tsx
+import {
+  StatCard, StatusDot, Badge, LineChart, AreaChart, BarChart,
+  EventFeed, Spinner, EmptyState, SectionHeader, MonoText,
+  LogViewer, ButtonGroup, useGlobalFilters,
+} from '@cameleer/design-system'
+```
+
+New:
+```tsx
+import {
+  StatCard, StatusDot, Badge,
+  ThemedChart, Line, Area, ReferenceLine, CHART_COLORS,
+  EventFeed, Spinner, EmptyState, SectionHeader, MonoText,
+  LogViewer, ButtonGroup, useGlobalFilters,
+} from '@cameleer/design-system'
+```
+
+- [ ] **Step 3: Replace data prep — JVM metrics**
+
+Replace the 4 JVM series useMemo blocks (cpuSeries, heapSeries, threadSeries, gcSeries) with flat data builders:
+
+```tsx
+  const formatTime = (t: string) =>
+    new Date(t).toLocaleTimeString([], { hour: '2-digit', minute: '2-digit' });
+
+  // JVM chart data — merge all metrics into flat objects by time bucket
+  const cpuData = useMemo(() => {
+    const pts = jvmMetrics?.metrics?.['process.cpu.usage.value'];
+    if (!pts?.length) return [];
+    return pts.map((p: any) => ({ time: p.time, cpu: p.value * 100 }));
+  }, [jvmMetrics]);
+
+  const heapData = useMemo(() => {
+    const pts = jvmMetrics?.metrics?.['jvm.memory.used.value'];
+    if (!pts?.length) return [];
+    return pts.map((p: any) => ({ time: p.time, heap: p.value / (1024 * 1024) }));
+  }, [jvmMetrics]);
+
+  const threadData = useMemo(() => {
+    const pts = jvmMetrics?.metrics?.['jvm.threads.live.value'];
+    if (!pts?.length) return [];
+    return pts.map((p: any) => ({ time: p.time, threads: p.value }));
+  }, [jvmMetrics]);
+
+  const gcData = useMemo(() => {
+    const pts = jvmMetrics?.metrics?.['jvm.gc.pause.total_time'];
+    if (!pts?.length) return [];
+    return pts.map((p: any) => ({ time: p.time, gc: p.value }));
+  }, [jvmMetrics]);
+```
+
+- [ ] **Step 4: Replace data prep — throughput and error**
+
+Replace the throughputSeries and errorSeries useMemo blocks:
+
+```tsx
+  const throughputData = useMemo(() => {
+    if (!chartData.length) return [];
+    return chartData.map((d: any) => ({ time: d.date.toISOString(), throughput: d.throughput }));
+  }, [chartData]);
+
+  const errorData = useMemo(() => {
+    if (!chartData.length) return [];
+    return chartData.map((d: any) => ({ time: d.date.toISOString(), errorPct: d.errorPct }));
+  }, [chartData]);
+```
+
+- [ ] **Step 5: Replace chart JSX — CPU Usage**
+
+Replace the CPU chart card content:
+
+```tsx
+          {cpuData.length ? (
+            <ThemedChart data={cpuData} height={160} xDataKey="time"
+              xTickFormatter={formatTime} yLabel="%">

+            <EmptyState title="No data" description="No CPU metrics available" />
+          )}
+```
+
+- [ ] **Step 6: Replace chart JSX — Memory (Heap)**
+
+Replace the heap chart card content:
+
+```tsx
+          {heapData.length ? (
+            <ThemedChart data={heapData} height={160} xDataKey="time"

+- [ ] **Step 7: Replace chart JSX — Throughput**
+
+```tsx
+          {throughputData.length ? (
+            <ThemedChart data={throughputData} height={160} xDataKey="time"

+
+```bash
+cd C:\Users\Hendrik\Documents\projects\cameleer3-server\ui
+npm run build
+```
+
+Expected: Build succeeds.
+
+- [ ] **Step 13: Commit and push**
+
+```bash
+cd C:\Users\Hendrik\Documents\projects\cameleer3-server
+git add ui/
+git commit -m "feat: migrate agent charts to ThemedChart + Recharts

+# Composable Sidebar Refactor
+
+**Date:** 2026-04-02
+**Upstream issue:** cameleer3-server #112
+
+## Why
+
+The current `Sidebar` component is monolithic. It hardcodes three navigation sections (Applications, Agents, Routes), a starred items section, bottom links (Admin, API Docs), and all tree-building logic (`buildAppTreeNodes`, `buildRouteTreeNodes`, `buildAgentTreeNodes`). The consuming application can only pass `SidebarApp[]` data — it cannot control what sections exist, what order they appear in, or add new sections without modifying this package.
+
+This blocks two features the consuming application needs:
+1. **Admin accordion** — when the user enters admin context, the sidebar should expand an Admin section and collapse operational sections, all controlled by the application
+2. **Icon-rail collapse** — the sidebar should collapse to a narrow icon strip, like modern app sidebars (Linear, VS Code, etc.)
+
+## Goal
+
+Refactor `Sidebar` into a composable compound component. The DS provides the frame and building blocks. The consuming application controls all content.
+
+## Current Exports (to be replaced)
+
+```typescript
+// Current — monolithic
+export { Sidebar } from './Sidebar/Sidebar'
+export type { SidebarApp, SidebarRoute, SidebarAgent } from './Sidebar/Sidebar'
+```
+
+## New Exports
+
+```typescript
+// New — composable
+export { Sidebar } from './Sidebar/Sidebar'
+export { SidebarTree } from './Sidebar/SidebarTree'
+export type { SidebarTreeNode } from './Sidebar/SidebarTree'
+export { useStarred } from './Sidebar/useStarred'
+```
+
+`SidebarApp`, `SidebarRoute`, `SidebarAgent` types are removed — they are application-domain types that move to the consuming app.
+
+## Compound Component API
+
+### `<Sidebar>`
+
+The outer shell. Renders the sidebar frame with an optional search input and collapse toggle.
+
+```tsx
+<Sidebar
+  collapsed={false}
+  onCollapseToggle={() => {}}
+  searchValue=""
+  onSearchChange={(query) => {}}
+  className=""
+>
+  <Sidebar.Header ... />
+  <Sidebar.Section ... />
+  <Sidebar.Section ... />
+  <Sidebar.Footer ... />
+</Sidebar>
+```
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `collapsed` | `boolean` | `false` | Render as ~48px icon rail |
+| `onCollapseToggle` | `() => void` | - | Collapse/expand toggle clicked |
+| `onSearchChange` | `(query: string) => void` | - | Search input changed. Omit to hide search. |
+| `searchValue` | `string` | `''` | Controlled value for the search input |
+| `children` | `ReactNode` | - | Sidebar.Header, Sidebar.Section, Sidebar.Footer |
+| `className` | `string` | - | Additional CSS class |
+
+**Search state ownership:** The DS renders the search input as a dumb controlled input and calls `onSearchChange` on every keystroke. The consuming application owns the search state and passes it to each `SidebarTree` as `filterQuery`. This lets the app control filtering behavior (e.g., clear search when switching sections, filter only certain sections). The DS does not hold any search state internally.
+
+**Rendering rules:**
+- Expanded: full width (~260px), all content visible
+- Collapsed: ~48px wide, only icons visible, tooltips on hover
+- Width transition: `transition: width 200ms ease`
+- Collapse toggle button (`<<` / `>>` chevron) in top-right corner
+- Search input hidden when collapsed
+- Search input auto-positioned between `Sidebar.Header` and first `Sidebar.Section` (not above Header)
+
+### `<Sidebar.Header>`
+
+Logo, title, and version. In collapsed mode, renders only the logo centered.
+
+```tsx
+<Sidebar.Header
+  logo={<img src="..." />}
+  title="cameleer"
+  version="v3.2.1"
+/>
+```
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `logo` | `ReactNode` | - | Logo element |
+| `title` | `string` | - | App name (hidden when collapsed) |
+| `version` | `string` | - | Version text (hidden when collapsed) |
+
+### `<Sidebar.Section>`
+
+An accordion section with a collapsible header and content area.
+
+```tsx
+<Sidebar.Section
+  label="APPLICATIONS"
+  icon={<Box size={14} />}
+  collapsed={false}
+  onToggle={() => {}}
+  active={false}
+>
+  <SidebarTree nodes={nodes} ... />
+</Sidebar.Section>
+```
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `label` | `string` | - | Section header text (rendered uppercase via CSS) |
+| `icon` | `ReactNode` | - | Icon for header and collapsed rail |
+| `collapsed` | `boolean` | `false` | Whether children are hidden |
+| `onToggle` | `() => void` | - | Header clicked |
+| `children` | `ReactNode` | - | Content when expanded |
+| `active` | `boolean` | - | Override active highlight. If omitted, not highlighted. |
+
+**Expanded rendering:**
+```
+[icon] APPLICATIONS
+  (children rendered here)
+```
+
+**Collapsed rendering:**
+```
+[icon] APPLICATIONS
+```
+
+**In sidebar icon-rail mode:**
+```
+[icon]     <- centered, tooltip shows label on hover
+```
+
+Header has: icon and label (no chevron — the entire row is clickable). Active section gets the amber left-border accent (existing pattern). Clicking anywhere on the header row calls `onToggle`.
+
+**Implementation detail:** `Sidebar.Section` and `Sidebar.Header` need to know the parent's `collapsed` state to switch between expanded and icon-rail rendering. The `<Sidebar>` component provides `collapsed` and `onCollapseToggle` via React context (`SidebarContext`). Sub-components read from context — no prop drilling needed.
+
+**Icon-rail click behavior:** In collapsed mode, clicking a section icon fires both `onCollapseToggle` and `onToggle` simultaneously on the same click. The sidebar expands and the section opens in one motion. No navigation occurs — the user is expanding the sidebar to see what's inside, not committing to a destination. They click a tree item after the section is visible to navigate.
+
+### `<Sidebar.Footer>`
+
+Pinned to the bottom of the sidebar. Container for `Sidebar.FooterLink` items.
+
+```tsx
+<Sidebar.Footer>
+  <Sidebar.FooterLink icon={<FileText size={14} />} label="API Docs" onClick={() => {}} />
+</Sidebar.Footer>
+```
+
+In collapsed mode, footer links render as centered icons with tooltips.
+
+### `<Sidebar.FooterLink>`
+
+A single bottom link.
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `icon` | `ReactNode` | - | Link icon |
+| `label` | `string` | - | Link text (hidden when collapsed, shown as tooltip) |
+| `onClick` | `() => void` | - | Click handler |
+| `active` | `boolean` | `false` | Active state highlight |
+
+### `<SidebarTree>` (no changes, newly exported)
+
+Already exists at `Sidebar/SidebarTree.tsx`. No modifications needed — it already accepts all data via props. Just export it from the package.
+
+**Current props (unchanged):**
+
+| Prop | Type | Description |
+|------|------|-------------|
+| `nodes` | `SidebarTreeNode[]` | Tree data |
+| `selectedPath` | `string` | Currently active path for highlighting |
+| `filterQuery` | `string` | Search filter text |
+| `onNavigate` | `(path: string) => void` | Navigation callback |
+| `persistKey` | `string` | localStorage key for expand state |
+| `autoRevealPath` | `string \| null` | Path to auto-expand to |
+| `isStarred` | `(id: string) => boolean` | Star state checker |
+| `onToggleStar` | `(id: string) => void` | Star toggle callback |
+
+### `useStarred` hook (no changes, newly exported)
+
+Already exists at `Sidebar/useStarred.ts`. Export as-is.
+
+**Returns:** `{ starredIds, isStarred, toggleStar }`
+
+## What Gets Removed
+
+All of this application-specific logic is deleted from the DS:
+
+1. **`buildAppTreeNodes()`** (~30 lines) — transforms `SidebarApp[]` into `SidebarTreeNode[]`
+2. **`buildRouteTreeNodes()`** (~20 lines) — transforms apps into route tree nodes
+3. **`buildAgentTreeNodes()`** (~25 lines) — transforms apps into agent tree nodes with live-count badges
+4. **`collectStarredItems()`** (~20 lines) — gathers starred items across types
+5. **`StarredGroup`** sub-component (~30 lines) — renders grouped starred items
+6. **Hardcoded sections** (~100 lines) — Applications, Agents, Routes section rendering with localStorage persistence
+7. **Hardcoded bottom links** (~30 lines) — Admin and API Docs links
+8. **Auto-reveal effect** (~20 lines) — `sidebarRevealPath` effect
+9. **`SidebarApp`, `SidebarRoute`, `SidebarAgent` types** — domain types, not DS types
+10. **`formatCount()` helper** — number formatting, moves to consuming app
+
+Total: ~300 lines of application logic removed, replaced by ~150 lines of compound component shell.
+
+## CSS Changes
+
+### New styles needed
+
+- `.sidebarCollapsed` — narrow width (48px), centered icons
+- `.collapseToggle` — `<<` / `>>` button positioning
+- `.sectionIcon` — icon rendering in section headers
+- `.tooltip` — hover tooltips for collapsed mode
+- Width transition: `transition: width 200ms ease` on `.sidebar`
+
+### Styles that stay
+
+- `.sidebar` (modified: width becomes conditional)
+- `.searchWrap`, `.searchInput` (unchanged)
+- `.navArea` (unchanged)
+- All tree styles in `SidebarTree` (unchanged)
+
+### Styles removed
+
+- `.bottom`, `.bottomItem`, `.bottomItemActive` — replaced by `Sidebar.Footer` / `Sidebar.FooterLink` styles
+- `.starredSection`, `.starredGroup`, `.starredItem`, `.starredRemove` — starred rendering moves to app
+- `.section` — replaced by `Sidebar.Section` styles
+
+## File Structure After Refactor
+
+```

+├── Sidebar.tsx              # Compound component: Sidebar, Sidebar.Header,
+│                            # Sidebar.Section, Sidebar.Footer, Sidebar.FooterLink

+```
+
+## Testing
+
+Update `Sidebar.test.tsx` to test the compound component API:
+
+- Renders Header with logo, title, version
+- Renders Sections with labels and icons
+- Section toggle calls `onToggle`
+- Collapsed sections hide children
+- Sidebar collapsed mode renders icon rail
+- Collapse toggle calls `onCollapseToggle`
+- Footer links render with icons and labels
+- Collapsed mode hides labels, shows tooltips
+- Search input calls `onSearchChange`
+- Search hidden when sidebar collapsed
+- Section icon click in collapsed mode calls both `onCollapseToggle` and `onToggle`
+
+`SidebarTree` tests are unaffected.
+
+## Usage Example (for reference)
+
+This is how the consuming application (cameleer3-server) will use the new API. This code does NOT live in the design system — it's shown for context only.
+
+```tsx
+// In LayoutShell.tsx (consuming app)
+const [sidebarCollapsed, setSidebarCollapsed] = useState(false);
+const [filterQuery, setFilterQuery] = useState('');
+const [appsCollapsed, setAppsCollapsed] = useState(false);
+const [agentsCollapsed, setAgentsCollapsed] = useState(false);
+const [routesCollapsed, setRoutesCollapsed] = useState(true);
+const [adminCollapsed, setAdminCollapsed] = useState(true);
+
+// Accordion: entering admin expands admin, collapses others
+useEffect(() => {
+  if (isAdminPage) {
+    setAdminCollapsed(false);
+    setAppsCollapsed(true);
+    setAgentsCollapsed(true);
+    setRoutesCollapsed(true);
+  } else {
+    setAdminCollapsed(true);
+    // restore previous operational states
+  }
+}, [isAdminPage]);
+
+<Sidebar
+  collapsed={sidebarCollapsed}
+  onCollapseToggle={() => setSidebarCollapsed(v => !v)}
+  searchValue={filterQuery}
+  onSearchChange={setFilterQuery}
+>
+  <Sidebar.Header logo={<CameleerLogo />} title="cameleer" version="v3.2.1" />
+
+  {isAdminPage && (
+    <Sidebar.Section label="ADMIN" icon={<Settings size={14} />}
+      collapsed={adminCollapsed} onToggle={() => setAdminCollapsed(v => !v)}>
+      <SidebarTree nodes={adminNodes} ... filterQuery={filterQuery} />
+    </Sidebar.Section>
+  )}
+
+  <Sidebar.Section label="APPLICATIONS" icon={<Box size={14} />}
+    collapsed={appsCollapsed} onToggle={() => { setAppsCollapsed(v => !v); if (isAdminPage) nav('/exchanges'); }}>
+    <SidebarTree nodes={appNodes} ... filterQuery={filterQuery} />
+  </Sidebar.Section>
+
+  <Sidebar.Section label="AGENTS" icon={<Cpu size={14} />}
+    collapsed={agentsCollapsed} onToggle={() => { setAgentsCollapsed(v => !v); if (isAdminPage) nav('/exchanges'); }}>
+    <SidebarTree nodes={agentNodes} ... filterQuery={filterQuery} />
+  </Sidebar.Section>
+
+  <Sidebar.Section label="ROUTES" icon={<GitBranch size={14} />}
+    collapsed={routesCollapsed} onToggle={() => { setRoutesCollapsed(v => !v); if (isAdminPage) nav('/exchanges'); }}>
+    <SidebarTree nodes={routeNodes} ... filterQuery={filterQuery} />
+  </Sidebar.Section>
+
+  <Sidebar.Footer>
+    <Sidebar.FooterLink icon={<FileText size={14} />} label="API Docs" onClick={() => nav('/api-docs')} />
+  </Sidebar.Footer>
+</Sidebar>
+```
+
+## Mock App Migration — LayoutShell
+
+The 11 page files currently duplicating `<AppShell sidebar={<Sidebar apps={SIDEBAR_APPS} />}>` will be consolidated into a single `LayoutShell` component.
+
+### `src/layout/LayoutShell.tsx`
+
+Composes the sidebar once using the new compound API. All page-specific content is rendered via `<Outlet />`.
+
+```tsx
+// src/layout/LayoutShell.tsx
+export function LayoutShell() {
+  const [sidebarCollapsed, setSidebarCollapsed] = useState(false)
+  const [filterQuery, setFilterQuery] = useState('')
+  const [appsCollapsed, setAppsCollapsed] = useState(false)
+  const [agentsCollapsed, setAgentsCollapsed] = useState(false)
+  const [routesCollapsed, setRoutesCollapsed] = useState(false)
+  const { starredIds, isStarred, toggleStar } = useStarred()
+  const location = useLocation()
+  // ... build tree nodes from SIDEBAR_APPS, starred section, etc.
+
+  return (
+    <AppShell
+      sidebar={
+        <Sidebar
+          collapsed={sidebarCollapsed}
+          onCollapseToggle={() => setSidebarCollapsed(v => !v)}
+          searchValue={filterQuery}
+          onSearchChange={setFilterQuery}
+        >
+          <Sidebar.Header logo={...} title="cameleer" version="v3.2.1" />
+          <Sidebar.Section label="Applications" icon={...}
+            collapsed={appsCollapsed} onToggle={() => setAppsCollapsed(v => !v)}>
+            <SidebarTree nodes={appNodes} filterQuery={filterQuery} ... />
+          </Sidebar.Section>
+          <Sidebar.Section label="Agents" icon={...}
+            collapsed={agentsCollapsed} onToggle={() => setAgentsCollapsed(v => !v)}>
+            <SidebarTree nodes={agentNodes} filterQuery={filterQuery} ... />
+          </Sidebar.Section>
+          <Sidebar.Section label="Routes" icon={...}
+            collapsed={routesCollapsed} onToggle={() => setRoutesCollapsed(v => !v)}>
+            <SidebarTree nodes={routeNodes} filterQuery={filterQuery} ... />
+          </Sidebar.Section>
+          {/* Starred section built from useStarred + SIDEBAR_APPS */}
+          <Sidebar.Footer>
+            <Sidebar.FooterLink icon={...} label="Admin" ... />
+            <Sidebar.FooterLink icon={...} label="API Docs" ... />
+          </Sidebar.Footer>
+        </Sidebar>
+      }
+    >
+      <Outlet />
+    </AppShell>
+  )
+}
+```
+
+### Route structure change
+
+`App.tsx` switches from per-page `<Route element={<Page />}>` to a layout route:
+
+```tsx
+<Route element={<LayoutShell />}>
+  <Route path="/apps" element={<Dashboard />} />
+  <Route path="/apps/:id" element={<Dashboard />} />
+  ...all existing routes...
+</Route>
+```
+
+All tree-building helpers (`buildAppTreeNodes`, `buildRouteTreeNodes`, `buildAgentTreeNodes`), starred section logic (`collectStarredItems`, `StarredGroup`), `formatCount`, and `sidebarRevealPath` handling move from `Sidebar.tsx` into `LayoutShell.tsx`. Each page file loses its `<AppShell sidebar={...}>` wrapper and becomes just the page content.
+
+The Inventory page's `LayoutSection` keeps its own inline `<Sidebar>` demo with `SAMPLE_APPS` data — it's a showcase, not a navigation shell.
+
+## Breaking Change
+
+This is a **breaking change** to the `Sidebar` API. The old `<Sidebar apps={[...]} onNavigate={...} />` signature is removed entirely. The consuming application must migrate to the compound component API in the same release cycle.
+
+Coordinate: bump DS version, update server UI, deploy together.

+# Recharts Migration Design
+
+## Goal
+
+Replace the design system's hand-rolled SVG chart components (LineChart, AreaChart, BarChart) with Recharts-based implementations. The current custom charts have responsiveness issues (preserveAspectRatio distorting text), limited tooltip/axis formatting, and growing maintenance burden.
+
+## Architecture
+
+Add Recharts as a DS dependency. Replace the three custom chart components and `_chart-utils.ts` with a single `ThemedChart` wrapper component. Consumers compose Recharts elements (`<Line>`, `<Area>`, `<Bar>`, etc.) as children inside `<ThemedChart>`. The DS re-exports Recharts components so consumers don't need to add Recharts as a separate dependency.
+
+Sparkline stays hand-rolled SVG (no axes, no tooltips — Recharts is overkill).
+
+### What gets removed
+
+- `composites/LineChart/` directory (LineChart.tsx, LineChart.module.css)
+- `composites/AreaChart/` directory (AreaChart.tsx, AreaChart.module.css)
+- `composites/BarChart/` directory (BarChart.tsx, BarChart.module.css)
+- `composites/_chart-utils.ts`
+- `ChartSeries` and `DataPoint` type exports
+
+### What gets added
+
+- `composites/ThemedChart/ThemedChart.tsx` — wrapper component
+- `composites/ThemedChart/ChartTooltip.tsx` — internal themed tooltip
+- `composites/ThemedChart/ThemedChart.module.css`
+- Recharts re-exports from the DS barrel
+
+### What stays unchanged
+
+- `utils/rechartsTheme.ts` (now also used internally by ThemedChart)
+- `CHART_COLORS`
+- `primitives/Sparkline/`
+
+## Data Format
+
+Consumers use Recharts-native flat data format instead of the current `ChartSeries[]`:
+
+```tsx
+// Before (custom)
+const series = [
+  { label: 'CPU %', data: pts.map(p => ({ x: new Date(p.time), y: p.value * 100 })) }
+]
+<AreaChart series={series} height={160} yLabel="%" />
+
+// After (Recharts-native)
+const data = pts.map(p => ({ time: p.time, cpu: p.value * 100 }))
+<ThemedChart data={data} height={160} xDataKey="time" yLabel="%">
+  <Area dataKey="cpu" stroke={CHART_COLORS[0]} fill={CHART_COLORS[0]} fillOpacity={0.1} />
+</ThemedChart>
+```
+
+This is a breaking change. The migration cost is bounded — only `AgentInstance.tsx` in the server repo uses these components.
+
+## ThemedChart API
+
+```tsx
+interface ThemedChartProps {
+  data: Record<string, any>[]
+  height?: number                 // default 200
+  xDataKey?: string               // default "time"
+  xType?: 'number' | 'category'   // default "category"
+  xTickFormatter?: (value: any) => string
+  yTickFormatter?: (value: any) => string
+  yLabel?: string
+  children: React.ReactNode       // Recharts elements
+  className?: string
+}
+```
+
+ThemedChart renders internally:
+- `ResponsiveContainer` (width 100%, height from prop)
+- `ComposedChart` (supports mixing Line + Bar + Area in one chart)
+- `CartesianGrid` with `rechartsTheme.cartesianGrid`
+- `XAxis` with `rechartsTheme.xAxis` + formatter
+- `YAxis` with `rechartsTheme.yAxis` + formatter + label
+- `Tooltip` with custom `ChartTooltip` component
+
+## Tooltip
+
+ThemedChart provides a custom `ChartTooltip` component (internal, not exported) that:
+- Shows the x-value formatted as date/time in a header row (mono font, subtle border separator)
+- Shows each series with colored dot + label + formatted value
+- Uses DS tokens for styling (surface bg, border, shadow, mono font)
+
+Consumers can override by passing their own `<Tooltip content={...} />` as a child. Recharts uses the last Tooltip it finds, so a consumer-provided one replaces the default.
+
+## DS Re-exports
+
+Selected Recharts components re-exported so consumers don't need `recharts` in their own package.json:
+
+```tsx
+export { ThemedChart } from './ThemedChart/ThemedChart'
+export {
+  Line, Area, Bar, ReferenceLine, ReferenceArea,
+  Legend, Brush, ComposedChart,
+} from 'recharts'
+```
+
+More can be added on demand.
+
+## Consumer Migration — Server UI
+
+`AgentInstance.tsx` has 6 charts to migrate:
+
+| Chart | Before | After |
+|-------|--------|-------|
+| CPU Usage | `<AreaChart series={cpuSeries} threshold={...}>` | `<ThemedChart><Area dataKey="cpu" /><ReferenceLine y={85} /></ThemedChart>` |
+| Memory (Heap) | `<AreaChart series={heapSeries} threshold={...}>` | `<ThemedChart><Area dataKey="heap" /><ReferenceLine y={max} /></ThemedChart>` |
+| Throughput | `<LineChart series={throughputSeries}>` | `<ThemedChart><Line dataKey="throughput" /></ThemedChart>` |
+| Error Rate | `<LineChart series={errorSeries}>` | `<ThemedChart><Line dataKey="errorPct" /></ThemedChart>` |
+| Thread Count | `<LineChart series={threadSeries}>` | `<ThemedChart><Line dataKey="threads" /></ThemedChart>` |
+| GC Pauses | `<AreaChart series={gcSeries}>` | `<ThemedChart><Area dataKey="gc" /></ThemedChart>` |
+
+Data prep changes from building `ChartSeries[]` arrays to flat objects with named keys.
+
+## Not in Scope
+
+- Sparkline migration (no responsiveness issues, no axes/tooltips)
+- SaaS UI (no chart component usage)
+- Dashboard tab (already uses Recharts directly with `rechartsTheme`)
+- New chart types (treemap, radar, etc. — consumers compose these directly)
