# UI Structure

The UI has 4 main tabs: **Exchanges**, **Dashboard**, **Runtime**, **Deployments**.

- **Exchanges** — route execution search and detail (`ui/src/pages/Exchanges/`)
- **Dashboard** — metrics and stats with L1/L2/L3 drill-down (`ui/src/pages/DashboardTab/`)
- **Runtime** — live agent status, logs, commands (`ui/src/pages/RuntimeTab/`). AgentHealth supports compact view (dense health-tinted cards) and expanded view (full GroupCard+DataTable per app). View mode persisted to localStorage.
- **Deployments** — app management, JAR upload, deployment lifecycle (`ui/src/pages/AppsTab/`)
  - Config sub-tabs: **Monitoring | Resources | Variables | Traces & Taps | Route Recording**
  - Create app: full page at `/apps/new` (not a modal)
  - Deployment progress: `ui/src/components/DeploymentProgress.tsx` (7-stage step indicator)

**Admin pages** (ADMIN-only, under `/admin/`):
- **Sensitive Keys** (`ui/src/pages/Admin/SensitiveKeysPage.tsx`) — global sensitive key masking config. Shows agent built-in defaults as outlined Badge reference, editable Tag pills for custom keys, amber-highlighted push-to-agents toggle. Keys add to (not replace) agent defaults. Per-app sensitive key additions managed via `ApplicationConfigController` API. Note: `AppConfigDetailPage.tsx` exists but is not routed in `router.tsx`.

## Key UI Files

- `ui/src/router.tsx` — React Router v6 routes
- `ui/src/config.ts` — apiBaseUrl, basePath
- `ui/src/auth/auth-store.ts` — Zustand: accessToken, user, roles, login/logout
- `ui/src/api/environment-store.ts` — Zustand: selected environment (localStorage)
- `ui/src/components/ContentTabs.tsx` — main tab switcher
- `ui/src/components/ExecutionDiagram/` — interactive trace view (canvas)
- `ui/src/components/ProcessDiagram/` — ELK-rendered route diagram
- `ui/src/hooks/useScope.ts` — TabKey type, scope inference
- `ui/src/components/StartupLogPanel.tsx` — deployment startup log viewer (container logs from ClickHouse, polls 3s while STARTING)
- `ui/src/api/queries/logs.ts` — `useStartupLogs` hook for container startup log polling, `useLogs`/`useApplicationLogs` for bounded log search (single page), `useInfiniteApplicationLogs` for streaming log views (cursor-paginated, server-side source/level filters)
- `ui/src/api/queries/agents.ts` — `useAgents` for agent list, `useInfiniteAgentEvents` for cursor-paginated timeline stream
- `ui/src/hooks/useInfiniteStream.ts` — tanstack `useInfiniteQuery` wrapper with top-gated auto-refetch, flattened `items[]`, and `refresh()` invalidator
- `ui/src/components/InfiniteScrollArea.tsx` — scrollable container with IntersectionObserver top/bottom sentinels. Streaming log/event views use this + `useInfiniteStream`. Bounded views (LogTab, StartupLogPanel) keep `useLogs`/`useStartupLogs`

## Alerts

- **Sidebar section** (`buildAlertsTreeNodes` in `ui/src/components/sidebar-utils.ts`) — Inbox, Rules, Silences.
- **Routes** in `ui/src/router.tsx`: `/alerts` (redirect to inbox), `/alerts/inbox`, `/alerts/rules`, `/alerts/rules/new`, `/alerts/rules/:id`, `/alerts/silences`. No redirects for the retired `/alerts/all` and `/alerts/history` — stale URLs 404 per the clean-break policy.
- **Pages** under `ui/src/pages/Alerts/`:
  - `InboxPage.tsx` — single filterable inbox. Filters: severity (multi), state (PENDING/FIRING/RESOLVED, default FIRING), Hide acked toggle (default on), Hide read toggle (default on). Row actions: Acknowledge, Mark read, Silence rule… (duration quick menu), Delete (OPERATOR+, soft-delete with undo toast wired to `useRestoreAlert`). Bulk toolbar (selection-driven): Acknowledge N · Mark N read · Silence rules · Delete N (ConfirmDialog; OPERATOR+).
  - `SilenceRuleMenu.tsx` — DS `Dropdown`-based duration picker (1h / 8h / 24h / Custom…). Used by the row-level and bulk silence actions. "Custom…" navigates to `/alerts/silences?ruleId=<id>`.
  - `RulesListPage.tsx` — CRUD + enable/disable toggle + env-promotion dropdown (pure UI prefill, no new endpoint).
  - `RuleEditor/RuleEditorWizard.tsx` — 5-step wizard (Scope / Condition / Trigger / Notify / Review). `form-state.ts` is the single source of truth (`initialForm` / `toRequest` / `validateStep`). Seven condition-form subcomponents under `RuleEditor/condition-forms/` — including `AgentLifecycleForm.tsx` (multi-select event-type chips for the six-entry `AgentLifecycleEventType` allowlist + lookback-window input).
  - `SilencesPage.tsx` — matcher-based create + end-early. Reads `?ruleId=` search param to prefill the Rule ID field (driven by InboxPage's "Silence rule… → Custom…" flow).
  - `AlertRow.tsx` shared list row; `alerts-page.module.css` shared styling.
- **Components**:
  - `NotificationBell.tsx` — polls `/alerts/unread-count` every 30 s (paused when tab hidden via TanStack Query `refetchIntervalInBackground: false`).
  - `AlertStateChip.tsx`, `SeverityBadge.tsx` — shared state/severity indicators.
  - `MustacheEditor/` — CodeMirror 6 editor with variable autocomplete + inline linter. Shared between rule title/message, webhook body/header overrides, and (future) Admin Outbound Connection editor (reduced-context mode for URL).
  - `MustacheEditor/alert-variables.ts` — variable registry aligned with `NotificationContextBuilder.java`. Add new leaves here whenever the backend context grows.
- **API queries** under `ui/src/api/queries/`: `alerts.ts`, `alertRules.ts`, `alertSilences.ts`, `alertNotifications.ts`, `alertMeta.ts`. All env-scoped via `useSelectedEnv` from `alertMeta`.
- **CMD-K**: `buildAlertSearchData` in `LayoutShell.tsx` registers `alert` and `alertRule` result categories. Badges convey severity + state. Palette navigates directly to the deep-link path — no sidebar-reveal state for alerts.
- **Sidebar accordion**: entering `/alerts/*` collapses Applications + Admin + Starred (mirrors Admin accordion).
- **Top-nav**: `<NotificationBell />` is the first child of `<TopBar>`, sitting alongside `SearchTrigger` + status `ButtonGroup` + `TimeRangeDropdown` + `AutoRefreshToggle`.

## UI Styling

- Always use `@cameleer/design-system` CSS variables for colors (`var(--amber)`, `var(--error)`, `var(--success)`, etc.) — never hardcode hex values. This applies to CSS modules, inline styles, and SVG `fill`/`stroke` attributes. SVG presentation attributes resolve `var()` correctly. All colors use CSS variables (no hardcoded hex).
- Shared CSS modules in `ui/src/styles/` (table-section, log-panel, rate-colors, refresh-indicator, chart-card, section-card) — import these instead of duplicating patterns.
- Shared `PageLoader` component replaces copy-pasted spinner patterns.
- Design system components used consistently: `Select`, `Tabs`, `Toggle`, `Button`, `LogViewer`, `Label` — prefer DS components over raw HTML elements. `LogViewer` renders optional source badges (`container`, `app`, `agent`) via `LogEntry.source` field (DS v0.1.49+).
- Environment slugs are auto-computed from display name (read-only in UI).
- Brand assets: `@cameleer/design-system/assets/` provides `camel-logo.svg` (currentColor), `cameleer-{16,32,48,192,512}.png`, and `cameleer-logo.png`. Copied to `ui/public/` for use as favicon (`favicon-16.png`, `favicon-32.png`) and logo (`camel-logo.svg` — login dialog 36px, sidebar 28x24px).
- Sidebar generates `/exchanges/` paths directly (no legacy `/apps/` redirects). basePath is centralized in `ui/src/config.ts`; router.tsx imports it instead of re-reading `<base>` tag.
- Global user preferences (environment selection) use Zustand stores with localStorage persistence — never URL search params. URL params are for page-specific state only (e.g. `?text=` search query). Switching environment resets all filters and remounts pages.
