fix(security): resolve 32 pnpm audit vulnerabilities

Upgrade direct dependencies to patched versions:
- electron: 37.3.1 -> 39.8.5
- vite: 5.4.21 -> 6.4.2
- @tailwindcss/vite: 4.1.17 -> 4.2.4
- fastify: 5.8.4 -> 5.8.5
- uuid: 13.0.0 -> 14.0.0
- Remove @types/uuid (uuid 14 ships its own types)

Add pnpm.overrides to force transitive deps:
- fastify, tar, @octokit/request-error,
  @octokit/plugin-paginate-rest, @octokit/request,
  tmp, @tootallnate/once, esbuild

pnpm audit: 0 vulnerabilities (was 32: 6L/15M/11H)

+# lodash-es-runtime-guards
+
+Replace runtime `typeof` checks and ad-hoc empty-string checks with `lodash-es` predicates.
+
+## When to Use
+
+- You see runtime checks like `typeof value === 'string'`.
+- You see object guards like `value && typeof value === 'object'`.
+- You see emptiness checks like `value.trim() !== ''` or `value.trim() === ''`.
+- You want consistent guard style across app, server, IPC, and tests.
+
+## Do Not Replace
+
+- Type-level `typeof` (TypeScript only), for example:
+  - `ReturnType<typeof fn>`
+  - `keyof typeof CONST_MAP`
+  - `z.infer<typeof Schema>`
+
+These are compile-time types and must remain as-is.
+
+## Guard Mapping
+
+- `typeof x === 'string'` -> `isString(x)`
+- `typeof x !== 'string'` -> `!isString(x)`
+- `typeof x === 'number'` -> `isNumber(x)`
+- `typeof x === 'boolean'` -> `isBoolean(x)`
+- `typeof x === 'function'` -> `isFunction(x)`
+- `typeof x === 'undefined'` -> `isUndefined(x)`
+- `x && typeof x === 'object'` -> `isObjectLike(x)`
+- `typeof x === 'object' && x !== null` -> `isObjectLike(x)`
+- `typeof x === 'object' && !Array.isArray(x)` -> `isObjectLike(x) && !isArray(x)`
+
+## String Emptiness Pattern
+
+- Prefer:
+  - `isEmpty(value.trim())`
+- Instead of:
+  - `value.trim() === ''`
+  - `value.trim() !== ''`
+  - `value.trim().length === 0`
+
+## Import Style
+
+- Use named imports from `lodash-es`:
+
+```ts
+import { isString, isNumber, isObjectLike, isEmpty } from 'lodash-es';
+```
+
+- Do not use full-package imports.
+- Reuse existing imports in file; avoid duplicate imports.
+
+## Refactor Checklist
+
+1. Replace runtime checks first, preserving behavior.
+2. Keep array/object branching semantics unchanged.
+3. Re-scan:
+
+```bash
+rg -n "typeof\s+[^\n]+(?:===|!==)\s*'" src
+```
+
+4. Confirm only type-level `typeof` remains:
+
+```bash
+rg -n "\btypeof\b" src
+```
+
+5. Run verification:
+
+```bash
+npm run type-check
+```
+

+## Design Context
+
+### Users
+
+Developers and power users who manage multiple AI accounts (Google Gemini, Claude) through a desktop Electron app. They use IDEs like Cursor, OpenCode, and Windsurf. They need to monitor token usage across accounts in real-time to avoid quota exhaustion.
+
+### Brand Personality
+
+- **Professional**: Clean, precise, no clutter
+- **Technical**: Data-dense but readable, developer-friendly
+- **Efficient**: Information at a glance, minimal clicks
+- 3 words: "precise", "technical", "focused"
+
+### Aesthetic Direction
+
+- Dark mode primary (this is a developer tool used for long sessions)
+- Deep navy/slate backgrounds, not pure black
+- Sharp accent colors for data visualization (subtle blues, teals, amber for warnings)
+- High information density without visual noise
+- Monospace for numbers/data, clean sans-serif for UI chrome
+- No gradients on text, no glassmorphism, no rounded-everything
+
+### Design Principles
+
+1. Data first — charts and numbers are the heroes
+2. Every pixel earns its place — no decorative elements
+3. Density over whitespace — developers want to see everything
+4. Motion only for state changes — no gratuitous animations
+5. Consistent with shadcn/ui + Tailwind system already in place

+Here is the code review report for the Token Usage Counter feature.
+
+## Summary
+
+The review found 2 critical security issues and 2 warnings. The overall architecture is solid, but the security issues must be addressed before this code is merged.
+
+## Critical Issues
+
+### CR-01: SQL Injection Vulnerability in TokenUsageRepo filter methods
+
+**Issue:** `buildAccountFilter` concatenates `accountId` directly into raw SQL.
+**Fix:** Use parameterized queries.
+
+```typescript
+function buildAccountFilter(accountId?: string): { sql: string; params: string[] } {
+  return accountId ? { sql: `AND account_id = ?`, params: [accountId] } : { sql: '', params: [] };
+}
+```
+
+### CR-02: Missing validation in TokenUsageRepo queries
+
+**Issue:** `buildDateFilter` directly interpolates `start` and `end` arguments.
+**Fix:** Ensure parameters are passed safely using parameterized queries.
+
+```typescript
+function buildDateFilter(start?: number, end?: number): { sql: string; params: number[] } {
+  const conditions: string[] = [];
+  const params: number[] = [];
+  if (start !== undefined) {
+    conditions.push(`timestamp >= ?`);
+    params.push(start);
+  }
+  if (end !== undefined) {
+    conditions.push(`timestamp <= ?`);
+    params.push(end);
+  }
+  return {
+    sql: conditions.length > 0 ? `AND ${conditions.join(' AND ')}` : '',
+    params,
+  };
+}
+```
+
+## Warnings
+
+### WR-01: Synchronous Database Writing in ProxyService
+
+**Issue:** `recordUsage` calls a synchronous database insertion on every proxy request, which can cause severe performance bottlenecks under load.
+**Fix:** Consider making the usage recording asynchronous (fire-and-forget), using an asynchronous database driver, or implementing a batching mechanism.
+
+### WR-02: Missing Unsubscribe / Cleanup in React Query hooks
+
+**Issue:** The usage dashboard queries lack an auto-refresh mechanism.
+**Fix:** Add `refetchInterval: 10000` to the query configuration.
+
+## Info
+
+Consider using CSS variables for the Recharts colors instead of hardcoded hex values to support light/dark mode better.

+
+## Summary
+
+This review covers the new Token Usage Counter feature introduced in the `feature/token-usage-counter` branch. The feature introduces a new `token_usage` table in SQLite, an IPC router and UI components for displaying token usage dashboards with charts, and hooks into `ProxyService` to record usage per request.
+
+Overall the architecture is well-structured and aligns with the existing project layout. The introduction of `TokenUsageRepo` directly querying the DB with `getCloudDb()` is consistent with the rest of the app. The UI is built using Recharts and properly localized.
+
+However, there are several **critical security and architecture issues** relating to SQLite usage (specifically SQL injection vulnerabilities in `TokenUsageRepo`) and some minor logic/performance concerns.
+
+## Critical Issues
+
+### CR-01: SQL Injection Vulnerability in TokenUsageRepo filter methods
+
+**File:** `src/ipc/database/usageHandler.ts:33-35`
+**Issue:** The `buildAccountFilter` function directly concatenates the `accountId` string into the SQL query without using parameterized queries or escaping. This allows for SQL injection if an attacker can manipulate the `accountId` value.
+**Fix:**
+Use parameterized queries (e.g., `?` placeholders) and pass the `accountId` as an argument to `raw.prepare().all(accountId)`.
+
+```typescript
+function buildAccountFilter(accountId?: string): { sql: string; params: string[] } {
+  return accountId ? { sql: `AND account_id = ?`, params: [accountId] } : { sql: '', params: [] };
+}
+```
+
+### CR-02: Missing try-catch and cleanup around database connection in TokenUsageRepo queries
+
+**File:** `src/ipc/database/usageHandler.ts:89`
+**Issue:** In `TokenUsageRepo`, the schema explicitly sets `timestamp` as an `integer`, but `start` and `end` arguments are directly interpolated into the query via `buildDateFilter` (lines 23-29). If `start` or `end` are somehow strings, this could also lead to SQL injection.
+**Fix:**
+Ensure `start` and `end` are strictly validated as integers before passing to the query, or use parameterized queries.
+
+```typescript
+function buildDateFilter(start?: number, end?: number): { sql: string; params: number[] } {
+  const conditions: string[] = [];
+  const params: number[] = [];
+  if (start !== undefined) {
+    conditions.push(`timestamp >= ?`);
+    params.push(start);
+  }
+  if (end !== undefined) {
+    conditions.push(`timestamp <= ?`);
+    params.push(end);
+  }
+  return {
+    sql: conditions.length > 0 ? `AND ${conditions.join(' AND ')}` : '',
+    params,
+  };
+}
+```
+
+## Warnings
+
+### WR-01: Synchronous Database Writing in ProxyService
+
+**File:** `src/server/modules/proxy/proxy.service.ts:57`
+**Issue:** The `recordUsage` method calls `this.tokenUsageService.recordUsage()`, which internally calls `TokenUsageRepo.recordUsage()`. `TokenUsageRepo.recordUsage()` performs a synchronous database insertion (`orm.insert(...).run()`) and closes the connection. Since this is called for every single proxy request (in `handleAnthropicMessages` and `handleOpenAIMessages`), the synchronous opening, inserting, and closing of the database connection could severely impact the performance and throughput of the proxy service under high load.
+**Fix:** Consider making the usage recording asynchronous (fire-and-forget), using an asynchronous database driver, or implementing a batching mechanism for token usage recording to avoid blocking the proxy request cycle.
+
+### WR-02: Missing Unsubscribe / Cleanup in React Query hooks
+
+**File:** `src/routes/usage.tsx`
+**Issue:** The `useQuery` hooks are configured properly, but the UI lacks an auto-refresh mechanism. Given this is a dashboard tracking live API usage, it might be beneficial to include a `refetchInterval` or a manual refresh button.
+**Fix:** Add `refetchInterval: 10000` to the query configuration.
+
+## Info
+
+### IN-01: UI Chart Colors and Styling
+
+**File:** `src/routes/usage.tsx:23`
+**Issue:** The `COLORS` array is hardcoded with hex values. In a themable application (e.g., light/dark mode), these colors might not adapt correctly, potentially causing visibility issues on certain backgrounds.
+**Fix:** Consider using CSS variables from the theme (e.g., `hsl(var(--primary))`) instead of hardcoded hex colors for Recharts components.

+# Proxy Page — Feature Brainstorm
+
+> Generated from designer agent analysis of `src/routes/proxy.tsx`
+> Date: 2026-04-22
+
+## Current State
+The proxy page (`src/routes/proxy.tsx`) is a 724-line monolith that exposes basic proxy controls (start/stop, port, protocol, API key, code examples) but leaves significant value on the table. The backend (`ProxyService`, `ProxyModule`) already implements many advanced features with no UI exposure.
+
+## Proposed New Features
+
+### 1. Live Traffic Monitor
+- Real-time SSE/WebSocket feed of proxied requests
+- Show request method, model, account used, latency, token count
+- Filter by status (success, rate-limited, error)
+- Inspired by: Request logging already exists in `TrafficLogger`
+
+### 2. IDE Quick-Connect Panel
+- One-click copy of ready-to-use configurations for:
+  - Cursor (`settings.json` snippet)
+  - OpenCode (`.env` snippet)
+  - Windsurf (`config.yaml` snippet)
+  - Claude Code / CLI tools
+- Include the local IP, port, and API key pre-filled
+- QR code for mobile/quick access
+
+### 3. API Playground
+- Built-in Swagger/OpenAPI UI or custom test panel
+- Pre-loaded with all supported endpoints:
+  - `/v1/chat/completions` (OpenAI-compatible)
+  - `/v1/messages` (Anthropic-compatible)
+  - `/v1beta/models/...generateContent` (Gemini-native)
+- Allow sending test requests and viewing formatted responses
+- Show exact curl equivalent for every request
+
+### 4. Health Dashboard
+- Real-time metrics cards:
+  - Requests/minute
+  - Average latency (p50, p95, p99)
+  - Error rate %
+  - Active connections
+  - Circuit breaker status (open/closed/half-open)
+- Sparkline charts for the last 5 minutes
+- Color-coded status indicators
+
+### 5. Model Availability Status
+- Live grid showing which models are currently available
+- Per-model indicators:
+  - Green: available
+  - Yellow: rate-limited (retry after)
+  - Red: unavailable / quota exhausted
+- Show last-used time and remaining quota (if known)
+- Collapse/expand by provider (Gemini, Anthropic)
+
+### 6. Error Feed
+- Scrollable log of recent errors
+- Columns: timestamp, endpoint, model, account, error code, message
+- Click to expand full request/response
+- Filter by error type (rate limit, timeout, auth, network)
+- Export to JSON/CSV
+
+### 7. Connection Visualizer
+- Diagram showing: IDE → Proxy → Account Pool → Upstream API
+- Animated flow dots representing live requests
+- Highlight currently active account
+- Show queue depth / waiting requests
+- Simple but effective for understanding routing
+
+### 8. One-Click Diagnostics
+- "Run Diagnostics" button that performs:
+  - Check if proxy port is accessible
+  - Test each configured account
+  - Verify model mapping resolution
+  - Check upstream API reachability
+  - Validate API key format
+- Output: green checkmarks or detailed error report with fix suggestions
+
+### 9. Session Stats
+- Summary of current session since proxy started:
+  - Total requests handled
+  - Total tokens proxied
+  - Unique accounts used
+  - Top 3 models used
+  - Uptime counter
+- Resettable per-session (not persisted)
+
+---
+
+## Implementation Notes
+- Many of these features require new IPC endpoints in `src/ipc/proxy/router.ts`
+- Health metrics likely already exist in `ProxyService` but need exposure
+- Traffic logging exists via `TrafficLogger` — just needs UI
+- Model availability data is already fetched for the account pool page

+# Proxy Page — UI/UX Improvements
+
+> Generated from designer agent analysis of `src/routes/proxy.tsx`
+> Date: 2026-04-22
+
+## Current Pain Points
+1. **Visual noise**: Gradient backgrounds (`bg-gradient-to-br`) feel dated and clash with the dark, technical aesthetic
+2. **Information overload**: All content is visible at once — no progressive disclosure
+3. **Code examples dominate**: Large, always-visible code blocks push important controls below the fold
+4. **Inconsistent density**: Too much padding in some areas, cramped in others
+5. **Security concern**: API key is displayed in plain text with only a basic copy button
+6. **No status context**: User can't see which account/model is being used for requests
+
+## Proposed Improvements
+
+### 1. Remove Gradient Backgrounds
+- Replace `bg-gradient-to-br from-slate-800 to-slate-900` with solid `bg-card` or subtle borders
+- Use elevation (borders, subtle shadows) instead of gradients to create hierarchy
+- Align with the rest of the app which uses flat, technical styling
+
+### 2. Tabs-Based Layout
+Organize the page into tabs:
+- **Status** (default): Service state, quick actions, health metrics
+- **Routing**: Model mapping, account scheduling, protocol settings
+- **API Docs**: Code examples, endpoint documentation, IDE configs
+- **Logs**: Live traffic feed, error history
+
+### 3. Compact Protocol Selector
+- Current: large buttons with icons
+- Proposed: `Select` dropdown or compact segmented control
+- Save horizontal space for more important controls
+
+### 4. Collapsible Code Examples
+- Wrap each code block in a `Collapsible` or `Accordion`
+- Show only the title + language icon by default
+- Expand on click
+- Add nested tabs for different languages (cURL, Python, JavaScript, TypeScript)
+
+### 5. Security-Focused API Key Display
+- Mask the API key by default (show `sk-••••••••`)
+- Reveal on explicit "Show" toggle
+- Add "Regenerate" button with confirmation dialog
+- Show "Last used" timestamp
+- Add warning if key is the default/weak key
+
+### 6. Configurable Model Mapping Table
+- Instead of a static list, show an editable table:
+  - Requested model | Resolved model | Provider | Status
+- Allow users to add custom mappings
+- Show which mappings are active/inactive
+- Validate that resolved models exist in the account pool
+
+### 7. Account Quota Context
+- Show the currently selected "primary" account with its quota bar
+- If auto-switching is enabled, show "Pool Mode: Active (N accounts)"
+- Link to the account pool page for detailed management
+
+### 8. Toast Copy Feedback
+- When user clicks "Copy", show a `Toast` or `Sonner` notification
+- Current: no feedback — user doesn't know if copy succeeded
+- Message: "Copied to clipboard" or "Failed to copy"
+
+### 9. Health Metrics Stub
+- Even if backend metrics aren't wired yet, create the UI skeleton
+- Show placeholder charts with "Coming soon" badge
+- This sets expectations and makes the page feel more complete
+
+### 10. Empty States
+- When proxy is stopped, show a clear empty state:
+  - Icon: `ServerOff` from lucide
+  - Message: "Proxy is not running"
+  - Action: "Start Proxy" button prominently displayed
+- When no accounts are configured, show a CTA to add accounts
+
+---
+
+## Design Principles
+- **Density over whitespace**: This is a developer tool — show more information per pixel
+- **Progressive disclosure**: Hide advanced options behind tabs/accordions
+- **Immediate feedback**: Every action should have a visible result (toast, spinner, state change)
+- **Security first**: API keys and sensitive data should never be displayed casually

+# Proxy Page — Advanced Features Hidden in Backend
+
+> Generated from oracle agent analysis of `src/server/modules/proxy/`
+> Date: 2026-04-22
+
+## Discovery
+The backend (`ProxyService`, `ProxyController`, `ProxyModule`) implements many sophisticated features that are **completely invisible** in the current UI. The proxy page only shows: port, protocol, API key, and basic start/stop.
+
+## Hidden Backend Features
+
+### 1. Advanced Routing & Scheduling Controls
+**Backend location**: `proxy.service.ts`, `proxy-scheduler.service.ts`
+**What's implemented**:
+- `scheduler.maxRequestsPerAccount`: Limit requests per account before switching
+- `scheduler.maxWaitTime`: Max time to wait for an available account
+- `scheduler.retryAttempts`: Number of retries per request
+- `scheduler.backoffStrategy`: `exponential` | `linear` | `fixed`
+- `scheduler.priorityAccounts`: Array of account IDs to prioritize
+
+**UI exposure**: None. These are hardcoded or set via config files only.
+
+### 2. Live Traffic Inspector
+**Backend location**: `traffic-logger.service.ts`
+**What's implemented**:
+- `TrafficLogger` captures every request/response with metadata
+- Fields: timestamp, requestId, accountId, model, promptTokens, completionTokens, latency, status, error
+- Log rotation and cleanup policies
+- Export to JSON/CSV
+
+**UI exposure**: None. Logs are only written to files.
+
+### 3. Circuit Breaker Dashboard
+**Backend location**: `proxy-circuit-breaker.service.ts`
+**What's implemented**:
+- Per-account circuit breaker state: `CLOSED`, `OPEN`, `HALF_OPEN`
+- Failure threshold and recovery timeout
+- When open: requests fail fast without hitting the API
+- Metrics: failure rate, last failure time, consecutive successes
+
+**UI exposure**: None. Circuit breaker state is internal only.
+
+### 4. Parity Testing Sandbox
+**Backend location**: `proxy-parity.service.ts`
+**What's implemented**:
+- Send identical requests to multiple models simultaneously
+- Compare responses for consistency
+- Detect model drift or API changes
+- Configurable test suites
+
+**UI exposure**: None. Only accessible via manual API calls or scripts.
+
+### 5. Custom Model Mapping Table
+**Backend location**: `proxy-model-mapper.service.ts`
+**What's implemented**:
+- Dynamic model resolution: `claude-opus-4` → `gemini-3-flash`
+- User-defined mappings stored in database
+- Regex-based model matching
+- Fallback chain: if mapped model unavailable, try next
+
+**UI exposure**: A static, read-only list is shown. No editing capability.
+
+### 6. Upstream Proxy Configuration
+**Backend location**: `proxy-upstream.service.ts`
+**What's implemented**:
+- `upstreamProxy.url`: Route all traffic through another proxy
+- `upstreamProxy.auth`: Basic auth or bearer token for upstream
+- `upstreamProxy.bypassList`: Domains to bypass
+
+**UI exposure**: None. Set via environment variables only.
+
+### 7. IDE Integration Quick-Setup
+**Backend location**: `proxy-config.service.ts` — `generateIdeConfig()`
+**What's implemented**:
+- Generates ready-to-paste configs for:
+  - Cursor (`settings.json`)
+  - VS Code + Cline/Roo Code
+  - OpenCode (`.env`)
+  - Claude Code (`claude_desktop_config.json`)
+  - Generic OpenAI client
+- Includes local IP detection, port, and API key
+
+**UI exposure**: Code examples are generic curl snippets. No IDE-specific configs.
+
+### 8. Health & Performance Metrics
+**Backend location**: `proxy-metrics.service.ts`
+**What's implemented**:
+- Request latency histogram (p50, p95, p99)
+- Requests per minute counter
+- Error rate by status code
+- Active connection gauge
+- Token throughput (tokens/minute)
+- Account utilization percentage
+
+**UI exposure**: None. Metrics are only exposed via a `/metrics` endpoint for Prometheus.
+
+### 9. Request Replay & Debug Tool
+**Backend location**: `proxy-replay.service.ts`
+**What's implemented**:
+- Store recent requests (last 100 by default)
+- Replay any request with one click
+- Modify headers/body before replay
+- Compare original vs. replayed response
+- Export request as curl command
+
+**UI exposure**: None.
+
+### 10. Global Timeout & Max Wait Controls
+**Backend location**: `proxy-config.service.ts`
+**What's implemented**:
+- `requestTimeout`: Global timeout for all upstream requests
+- `connectTimeout`: TCP connection timeout
+- `maxWaitTime`: Max time to wait for an available account
+- `idleTimeout`: Close idle connections after N seconds
+
+**UI exposure**: None. Hardcoded defaults.
+
+---
+
+## Recommendation
+Create a new "Advanced" tab on the proxy page that exposes these features progressively:
+1. **Phase 1**: Read-only views (circuit breaker status, health metrics, traffic logs)
+2. **Phase 2**: Interactive controls (model mapping editor, scheduler settings)
+3. **Phase 3**: Power-user tools (replay, parity testing, upstream proxy config)
+
+This would transform the proxy page from a simple on/off switch into a comprehensive API gateway dashboard.

+> Generated from oracle agent analysis of `src/routes/proxy.tsx`
+> Date: 2026-04-22
+
+## Current State
+`src/routes/proxy.tsx` is a **724-line monolith** containing:
+- Route definition
+- State management (useState, useEffect, useMemo)
+- Data fetching (useQuery equivalents for proxy config, local IPs)
+- Derived state (code examples, URLs)
+- UI rendering (service card, model mapping, code examples, local access banner)
+- Event handlers (start/stop, copy, protocol change)
+- Constants and helper functions
+
+## Target Architecture
+Split into **7+ files** following the project's conventions:
+
+```
+src/
+├── routes/
+│   └── proxy.tsx              # ~50 lines — route definition + composition
+├── components/
+│   └── proxy/
+│       ├── ProxyServiceCard.tsx
+│       ├── ProxyModelMappingCard.tsx

+└── utils/
+    └── proxy.ts               # URL builders, formatters, parsers
+```
+
+## File Breakdown
+
+### 1. `src/hooks/useProxyConfig.ts`
+**Responsibility**: Fetch and mutate proxy configuration
+```typescript
+export function useProxyConfig() {
+  // Fetches from ipc.client.proxy.getConfig()
+  // Provides: config, isLoading, error, updateConfig, startProxy, stopProxy
+  // Handles optimistic updates for start/stop toggling
+}
+```
+
+### 2. `src/hooks/useLocalIps.ts`
+**Responsibility**: Get local IP addresses for the access banner
+```typescript
+export function useLocalIps() {
+  // Fetches from ipc.client.system.getLocalIps()
+  // Returns: ips[], isLoading, error
+}
+```
+
+### 3. `src/hooks/useProxyExamples.ts`
+**Responsibility**: Generate code examples based on current config
+```typescript
+export function useProxyExamples(config: ProxyConfig, localIps: string[]) {
+  // Returns memoized examples for curl, Python, Node.js
+  // Updates when port, protocol, or API key changes
+}
+```
+
+### 4. `src/components/proxy/ProxyServiceCard.tsx`
+**Responsibility**: The main service control card
+- Start/stop toggle
+- Port input
+- Protocol selector
+- API key display (with mask/reveal)
+- Status indicator
+
+### 5. `src/components/proxy/ProxyModelMappingCard.tsx`
+**Responsibility**: Model mapping display/editor
+- Read-only list (current state)
+- Future: editable table with add/remove
+- Show provider badges
+
+### 6. `src/components/proxy/ProxyUsageExamplesCard.tsx`
+**Responsibility**: Code examples section
+- Collapsible/accordion layout
+- Tabs for different languages
+- Copy-to-clipboard buttons
+- Syntax highlighting (if available)
+
+### 7. `src/components/proxy/ProxyLocalAccessBanner.tsx`
+**Responsibility**: "Access your proxy locally" banner
+- Show local IPs
+- QR code (future)
+- Copy URL buttons
+
+### 8. `src/constants/proxy.ts`
+**Responsibility**: Constants
+```typescript
+export const DEFAULT_PROXY_PORT = 3000;
+export const PROTOCOLS = ['http', 'https'] as const;
+export const EXAMPLE_MODELS = ['gpt-4o', 'claude-3-opus', 'gemini-pro'];
+```
+
+### 9. `src/utils/proxy.ts`
+**Responsibility**: Pure helper functions
+```typescript
+export function buildProxyUrl(protocol: string, ip: string, port: number): string;
+export function maskApiKey(key: string): string;
+export function formatCurlExample(url: string, model: string, apiKey: string): string;
+```
+
+## Route File After Refactoring
+
+```typescript
+// src/routes/proxy.tsx — ~50 lines
+import { createFileRoute } from '@tanstack/react-router';
+import { useProxyConfig } from '@/hooks/useProxyConfig';
+import { useLocalIps } from '@/hooks/useLocalIps';
+import { ProxyServiceCard } from '@/components/proxy/ProxyServiceCard';
+import { ProxyModelMappingCard } from '@/components/proxy/ProxyModelMappingCard';
+import { ProxyUsageExamplesCard } from '@/components/proxy/ProxyUsageExamplesCard';
+import { ProxyLocalAccessBanner } from '@/components/proxy/ProxyLocalAccessBanner';
+
+function ProxyPage() {
+  const { config, isLoading, startProxy, stopProxy } = useProxyConfig();
+  const { ips } = useLocalIps();
+
+  if (isLoading) return <ProxySkeleton />;
+
+  return (
+    <div className="space-y-6 p-6">
+      <ProxyServiceCard config={config} onStart={startProxy} onStop={stopProxy} />
+      <ProxyModelMappingCard mappings={config.modelMappings} />
+      <ProxyUsageExamplesCard config={config} ips={ips} />
+      <ProxyLocalAccessBanner ips={ips} port={config.port} />
+    </div>
+  );
+}
+
+export const Route = createFileRoute('/proxy')({ component: ProxyPage });
+```
+
+## Migration Steps
+1. Create new files (hooks, components, constants, utils)
+2. Move code from `proxy.tsx` to appropriate files
+3. Update imports in `proxy.tsx`
+4. Extract and test each hook independently
+5. Add Storybook stories for each component (if Storybook is used)
+6. Verify no regression in functionality
+
+## Benefits
+- **Testability**: Each hook and component can be unit tested in isolation
+- **Reusability**: `useLocalIps` can be used in other pages (e.g., settings)
+- **Maintainability**: 50-line route file vs. 724-line monolith
+- **Code review**: Smaller files = faster, more focused PRs
+- **Onboarding**: New developers can understand the page in minutes

+# Proxy Page — Code Quality Issues
+
+> Generated from fixer agent analysis of `src/routes/proxy.tsx`
+> Date: 2026-04-22
+
+## Severity Legend
+- 🔴 **Critical**: Bugs or crashes
+- 🟡 **High**: Performance or reliability issues
+- 🟢 **Medium**: Maintainability or best practice violations
+
+## Issues Found
+
+### 1. 🔴 State Duplication Between Proxy Config and Local State
+**Location**: Lines ~120-180
+**Issue**: The component maintains both `proxyConfig` (from IPC) and local `useState` copies for `port`, `protocol`, `apiKey`. These can drift out of sync if the backend config changes externally.
+**Fix**: Use a single source of truth. Either:
+- Derive local state from `proxyConfig` with `useEffect` sync
+- Or use `useQuery` with `staleTime: 0` and no local cache
+
+### 2. 🟡 Race Condition in Start/Stop Toggle
+**Location**: Lines ~200-250
+**Issue**: If user clicks start/stop rapidly, multiple IPC calls fire in parallel. The UI shows intermediate states that may not reflect the actual backend state.
+**Fix**: Disable the toggle button while a transition is in progress. Add an `isTransitioning` flag.
+
+### 3. 🟢 Clipboard Error Handling
+**Location**: Lines ~300-320
+**Issue**: `navigator.clipboard.writeText()` can fail (permission denied, not in secure context). The code has no try/catch.
+**Fix**:
+```typescript
+async function copyToClipboard(text: string) {
+  try {
+    await navigator.clipboard.writeText(text);
+    toast.success('Copied!');
+  } catch {
+    toast.error('Failed to copy');
+  }
+}
+```
+
+### 4. 🟢 Unstable Callbacks Causing Re-renders
+**Location**: Throughout
+**Issue**: Event handlers are defined inline in JSX, causing child components to re-render unnecessarily.
+**Fix**: Wrap handlers in `useCallback`:
+```typescript
+const handleStart = useCallback(() => startProxy(), [startProxy]);
+const handleStop = useCallback(() => stopProxy(), [stopProxy]);
+```
+
+### 5. 🟡 Memory Leak in setTimeout
+**Location**: Lines ~400-420
+**Issue**: A `setTimeout` is used for a "copy feedback" animation but is never cleared on unmount.
+**Fix**: Use `useEffect` cleanup:
+```typescript
+useEffect(() => {
+  const timer = setTimeout(() => setCopied(false), 2000);
+  return () => clearTimeout(timer);
+}, [copied]);
+```
+
+### 6. 🟢 Missing Loading States for Mutations
+**Location**: Lines ~200-250
+**Issue**: When starting/stopping the proxy, there's no loading spinner or disabled state on the button.
+**Fix**: Add `isPending` state to the mutation hook and disable the button + show spinner while pending.
+
+### 7. 🟢 Hardcoded i18n Strings
+**Location**: Throughout
+**Issue**: Many UI strings are hardcoded in English instead of using `useTranslation()`:
+- "Proxy Service"
+- "Start Proxy"
+- "Stop Proxy"
+- "Copy"
+- "Copied!"
+**Fix**: Extract all strings to `src/localization/i18n.ts` and use `t('proxy.startProxy')`, etc.
+
+### 8. 🟢 Magic Numbers
+**Location**: Lines ~450-500
+**Issue**: Port validation uses hardcoded `3000`, `65535` without constants.
+**Fix**:
+```typescript
+const MIN_PORT = 1024;
+const MAX_PORT = 65535;
+const DEFAULT_PORT = 3000;
+```
+
+### 9. 🟢 Unsafe Type Cast
+**Location**: Lines ~550-600
+**Issue**: `event.target.value` is cast to `Protocol` without validation.
+**Fix**:
+```typescript
+const protocol = event.target.value;
+if (!PROTOCOLS.includes(protocol)) return;
+setProtocol(protocol as Protocol);
+```
+
+### 10. 🟡 Dangerous Parsing of Local IPs
+**Location**: Lines ~650-700
+**Issue**: `localIps` is parsed from a shell command output using string splitting that could break on unexpected formats.
+**Fix**: Use a robust parser or, better, expose `os.networkInterfaces()` via a safe IPC endpoint.
+
+### 11. 🟢 Unnecessary Re-renders from Inline Objects
+**Location**: Lines ~350-380
+**Issue**: Inline style objects and arrays are recreated on every render, breaking `React.memo` optimizations in child components.
+**Fix**: Extract static styles outside the component or memoize:
+```typescript
+const cardStyle = useMemo(() => ({ padding: '1.5rem' }), []);
+```
+
+### 12. 🟢 No Validation on Port Input
+**Location**: Lines ~150-170
+**Issue**: User can type any value into the port field, including non-numbers, negatives, or out-of-range values.
+**Fix**: Add input validation:
+```typescript
+<input
+  type="number"
+  min={1024}
+  max={65535}
+  value={port}
+  onChange={(e) => {
+    const value = parseInt(e.target.value, 10);
+    if (value >= 1024 && value <= 65535) setPort(value);
+  }}
+/>
+```
+
+---
+
+## Testing Recommendations
+- Add unit tests for `useProxyConfig` hook (mock IPC client)
+- Test race conditions: rapid start/stop clicks
+- Test clipboard failure path
+- Test port validation edge cases (0, 80, 65536, NaN)
+- Test with `react-testing-library` + `user-event`

+
+## Key Observations
+1. **Backend is significantly more capable than the UI suggests** — 12 services vs. 1 page
+2. **IPC layer is thin** — most backend services are not exposed via IPC, only HTTP
+3. **ProxyConfig schema is the source of truth** — it documents everything the backend can do
+4. **No real-time communication** — UI polls for status; no WebSocket or SSE for live updates
+5. **Separation of concerns is good on backend**, terrible on frontend (724-line monolith)
+
+## Recommended Architecture Changes
+1. Extend `src/ipc/proxy/router.ts` to expose all `ProxyConfig` fields
+2. Add IPC endpoints for:
+   - `proxy.getTrafficLogs()`
+   - `proxy.getCircuitBreakerStatus()`
+   - `proxy.getMetrics()`
+   - `proxy.replayRequest()`
+3. Create a WebSocket or SSE channel for live traffic updates
+4. Refactor frontend into the 7-file structure proposed in `04-code-organization.md`

+## ✨ Por que o Gemini Nexus?
+
+Quando você usa suas IDEs favoritas, já encontrou estes problemas?
+
+- 😫 A cota da sua única conta acaba rápido, exigindo trocas manuais frequentes
+- 🔄 Gerenciar múltiplas contas do Google/Claude é cansativo
+- 📊 Você não sabe quanta cota resta na conta atual
+- 🔌 Precisa de um proxy local e confiável para suas ferramentas de desenvolvimento
+
+**Gemini Nexus** está aqui para resolver tudo isso! Ele é um app desktop profissional construído em Electron que te ajuda a:
+
+- ✅ **Contas Ilimitadas** - Adicione quantas contas Google Gemini / Claude quiser
+- ✅ **Troca Automática** - Troca inteligentemente para a próxima conta disponível quando o limite é atingido
+- ✅ **Monitoramento em Tempo Real** - Visualize o uso de cota de todas as contas
+- ✅ **Proxy de API Local** - Servidor proxy integrado compatível com OpenAI/Anthropic
+- ✅ **Criptografia Segura** - Criptografia AES-256-GCM para seus dados sensíveis
+
+---
+
+## 🌟 Melhorias sobre o Projeto Base

+**✅ Documento Completo: Integração com Custom Endpoint do OpenCode (Provedores Custom / OpenAI-Compatible)**
+
+OpenCode (https://opencode.ai) é um agente de IA para terminal que usa o **Vercel AI SDK** para se comunicar com provedores de LLM. Ele suporta nativamente provedores customizados via o pacote `@ai-sdk/openai-compatible`, que segue o padrão **OpenAI Chat Completions API** (`/v1/chat/completions`).
+
+Isso significa que **sua API precisa implementar exatamente o formato OpenAI-compatible** para que o OpenCode consiga conversar com ela diretamente.
+
+---
+
+### 1. Como Configurar um Provedor Custom no OpenCode
+
+Crie ou edite o arquivo de configuração (recomendado: `~/.config/opencode/opencode.json` ou `opencode.json` na raiz do projeto):
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "provider": {
+    "minha-ia-custom": {
+      "npm": "@ai-sdk/openai-compatible",
+      "name": "Minha IA Custom (OpenCode)",
+      "options": {
+        "baseURL": "https://sua-api.com/v1",
+        "apiKey": "sk-sua-chave-aqui-ou-{env:MINHA_API_KEY}",
+        "headers": {
+          "X-Custom-Header": "valor-opcional"
+        }
+      },
+      "models": {
+        "meu-modelo-principal": {
+          "name": "Meu Modelo Principal",
+          "limit": {
+            "context": 128000,
+            "output": 8192
+          }
+        },
+        "meu-modelo-rapido": {
+          "name": "Modelo Rápido",
+          "limit": {
+            "context": 32000,
+            "output": 4096
+          }
+        }
+      }
+    }
+  },
+  "model": "minha-ia-custom/meu-modelo-principal"
+}
+```
+
+**Campos importantes:**
+
+- `npm`: Sempre use `"@ai-sdk/openai-compatible"` para APIs que expõem `/v1/chat/completions`.
+- `baseURL`: URL base da sua API (deve terminar com `/v1`).
+- `apiKey`: Pode ser valor direto ou `{env:NOME_VARIAVEL}`.
+- `models`: Defina os modelos que sua API expõe. O `limit` ajuda o OpenCode a gerenciar contexto.
+- `model`: Define o modelo padrão no formato `provider_id/model_id`.
+
+Depois de salvar, reinicie o OpenCode ou use `/models` para selecionar.
+
+**Comando rápido para adicionar chave:**
+
+```bash
+opencode /connect
+# Escolha "Other" → digite o provider_id (ex: minha-ia-custom) → cole a API key
+```
+
+---
+
+### 2. Como o OpenCode Envia Requisições
+
+O OpenCode (via AI SDK) faz chamadas **POST** para:
+
+```
+POST {baseURL}/chat/completions
+```
+
+**Headers enviados:**
+
+- `Authorization: Bearer <sua-api-key>`
+- `Content-Type: application/json`
+- Headers customizados que você definir em `options.headers`
+
+**Payload típico (exemplo real):**
+
+```json
+{
+  "model": "meu-modelo-principal",
+  "messages": [
+    {
+      "role": "system",
+      "content": "Você é um assistente de código experiente..."
+    },
+    {
+      "role": "user",
+      "content": "Crie uma função em Python que..."
+    }
+  ],
+  "stream": true,
+  "temperature": 0.7,
+  "max_tokens": 8192,
+  "tools": [
+    /* array de tools se o agente estiver usando ferramentas */
+  ],
+  "tool_choice": "auto"
+}
+```
+
+**Parâmetros comuns que o OpenCode envia:**
+
+- `messages` (array completo do histórico)
+- `stream: true` (quase sempre, para UX em tempo real)
+- `temperature`, `max_tokens`, `top_p`
+- `tools` + `tool_choice` (quando usa agentes com ferramentas/MCP)
+- `response_format` (às vezes)
+- `providerOptions` (opções específicas do provedor – raras no openai-compatible)
+
+---
+
+### 3. Como o OpenCode Recebe e Processa Respostas
+
+#### A. Streaming (recomendado – usado na maioria das interações)
+
+Sua API deve responder com `Content-Type: text/event-stream` e eventos SSE:
+
+```
+data: {"id":"chatcmpl-123","object":"chat.completion.chunk","created":1712345678,"model":"meu-modelo-principal","choices":[{"index":0,"delta":{"content":"Olá"},"finish_reason":null}]}
+
+data: {"id":"chatcmpl-123","choices":[{"index":0,"delta":{"content":"! Como"},"finish_reason":null}]}
+
+data: [DONE]
+```
+
+O OpenCode processa cada chunk em tempo real.
+
+#### B. Resposta não-streaming (completa)
+
+```json
+{
+  "id": "chatcmpl-123",
+  "object": "chat.completion",
+  "created": 1712345678,
+  "model": "meu-modelo-principal",
+  "choices": [
+    {
+      "index": 0,
+      "message": {
+        "role": "assistant",
+        "content": "Resposta completa aqui..."
+      },
+      "finish_reason": "stop"
+    }
+  ],
+  "usage": {
+    "prompt_tokens": 150,
+    "completion_tokens": 320,
+    "total_tokens": 470
+  }
+}
+```
+
+#### Suporte a Tool Calling (essencial para agentes)
+
+Se sua API suportar `tools`, o OpenCode pode:
+
+1. Enviar `tools` na requisição.
+2. Receber `tool_calls` na resposta.
+3. Executar a ferramenta (via MCP ou built-in).
+4. Enviar o resultado de volta como mensagem `tool`.
+
+**Exemplo de resposta com tool call:**
+
+```json
+{
+  "choices": [
+    {
+      "message": {
+        "role": "assistant",
+        "tool_calls": [
+          {
+            "id": "call_123",
+            "type": "function",
+            "function": {
+              "name": "read_file",
+              "arguments": "{\"path\": \"src/app.ts\"}"
+            }
+          }
+        ]
+      }
+    }
+  ]
+}
+```
+
+---
+
+### 4. Como é Exibido no Chat do OpenCode (TUI)
+
+- **Streaming**: Texto aparece caractere por caractere com efeito de digitação.
+- **Markdown**: Suporte completo a código (syntax highlight), listas, tabelas, etc.
+- **Tool Calls**: Mostra “Executando ferramenta: read_file...” + resultado.
+- **Multi-turn**: Mantém histórico completo na conversa.
+- **Erros**: Mostra mensagens de erro claras no terminal.
+- **Contexto**: Respeita os limites de `context` e `output` que você definiu no config.
+
+O OpenCode usa o TUI (Terminal User Interface) baseado em React/Ink para renderizar tudo de forma bonita.
+
+---
+
+### 5. Requisitos Mínimos da Sua API para Funcionar Perfeitamente
+
+| Recurso                | Obrigatório? | Recomendado? | Observação                         |
+| ---------------------- | ------------ | ------------ | ---------------------------------- |
+| `/v1/chat/completions` | Sim          | -            | Endpoint principal                 |
+| Streaming (SSE)        | Sim          | -            | Essencial para UX                  |
+| Tool Calling           | Não          | Sim          | Para agentes completos             |
+| System messages        | Sim          | -            | -                                  |
+| Multi-turn history     | Sim          | -            | -                                  |
+| Usage stats            | Não          | Sim          | Mostra tokens gastos               |
+| Error handling         | Sim          | -            | Retorne JSON de erro padrão OpenAI |
+
+**Endpoint exato esperado:**  
+`POST https://sua-api.com/v1/chat/completions`
+
+---
+
+### 6. Exemplo Completo de Configuração + Teste
+
+1. Configure o `opencode.json` como acima.
+2. Rode:
+   ```bash
+   opencode
+   ```
+3. Digite algo ou use `/models` para selecionar seu provedor.
+4. Teste com:
+   ```bash
+   curl -X POST https://sua-api.com/v1/chat/completions \
+     -H "Authorization: Bearer sk-..." \
+     -H "Content-Type: application/json" \
+     -d '{"model":"meu-modelo-principal","messages":[{"role":"user","content":"Olá"}],"stream":true}'
+   ```
+
+---
+
+### 7. Troubleshooting Comum
+
+- **“Route not found” ou requests indo para lugar errado** → Verifique se `baseURL` termina com `/v1` e não com `/v1/chat/completions`.
+- **Custom provider não aparece** → Certifique-se que o ID do provider no `/connect` bate com a chave no `opencode.json`.
+- **Sem streaming / resposta lenta** → Implemente SSE corretamente.
+- **Tool calls não funcionam** → Sua API precisa retornar `tool_calls` no formato OpenAI exato.
+- **Erro de autenticação** → Use `apiKey` ou `headers` corretamente.
+
+---
+
+### Referências Oficiais
+
+- **Docs Principais**: https://opencode.ai/docs/providers/
+- **Models**: https://opencode.ai/docs/models/
+- **Config**: https://opencode.ai/docs/config/
+- **Schema de Config**: https://opencode.ai/config.json
+- **GitHub**: https://github.com/anomalyco/opencode
+- **AI SDK OpenAI-Compatible**: https://ai-sdk.dev/providers/openai-compatible-providers
+
+---
+
+**Resumo Final para Você (que está construindo a API):**
+
+Sua API **precisa ser 100% compatível** com o endpoint OpenAI `/v1/chat/completions` (streaming + tool calling recomendado).  
+O OpenCode vai:
+
+1. Configurar via `opencode.json` (baseURL + apiKey)
+2. Enviar requisições padrão OpenAI
+3. Receber streaming ou resposta completa
+4. Renderizar tudo lindamente no TUI com suporte a ferramentas
+
+Se você implementar exatamente o padrão OpenAI Chat Completions, vai funcionar perfeitamente com o OpenCode.
+
+Quer que eu monte um **exemplo de servidor mínimo** (em Node.js/Fastify ou Python/FastAPI) que já funcione com o OpenCode? Posso criar um template completo para você.

+# Proxyman Debugging Guide for Antigravity and Gemini Nexus
+
+This guide explains how to use Proxyman for two debugging targets:
+
+1. The installed official `Antigravity` desktop client
+2. The `Gemini Nexus` development build from this repository
+
+Before you start, complete [Proxyman Installation and Basic Setup on Windows](./proxyman-install.md).
+
+## Scope
+
+Use this guide when you want to:
+
+- inspect login, quota, project context, or model-list requests from `Antigravity`
+- inspect OAuth, quota refresh, or proxy traffic from `Gemini Nexus`
+- compare requests from the official client with requests produced by this project
+
+## Understand the Two Traffic Paths
+
+### Official `Antigravity` Client
+
+`Antigravity` is an Electron application. Its traffic may come from:
+
+- Chromium or renderer-side requests
+- Electron or Node-side requests
+
+### `Gemini Nexus` in This Repository
+
+This project is also an Electron app, but it additionally includes Node, Undici, and internal proxy flows. You may need to inspect:
+
+- Electron main-process outbound requests
+- renderer-side requests
+- upstream requests emitted by `src/server/`
+
+## Debug the Installed Official Antigravity Client
+
+### Recommended Path: Use the Repository Script
+
+Use the provided script:
+
+- [scripts/start-antigravity-with-proxyman.ps1](../scripts/start-antigravity-with-proxyman.ps1)
+
+This should be the default path for the installed official client because it already does the following:
+
+- sets `HTTP_PROXY`, `HTTPS_PROXY`, and `ALL_PROXY`
+- sets `NODE_EXTRA_CA_CERTS`
+- passes `--proxy-server` and `--proxy-bypass-list`
+- stops existing `Antigravity` processes so the new environment takes effect
+
+Typical usage:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\start-antigravity-with-proxyman.ps1
+```
+
+If Proxyman is using a different port:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\start-antigravity-with-proxyman.ps1 -Port 9091
+```
+
+If you are temporarily debugging TLS failures:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\start-antigravity-with-proxyman.ps1 -AllowInsecureTls
+```
+
+Notes:
+
+- This script targets the installed official `Antigravity` client.
+- It does not launch this repository's `Gemini Nexus` development build.
+- Override `-AppPath`, `-CaPath`, `-ProxyHost`, or `-NoProxy` if your local environment differs.
+
+### Suggested Flow
+
+1. Open Proxyman.
+2. Confirm that installation and certificate setup are already complete.
+3. Confirm the local proxy port, for example `9090`.
+4. Launch `Antigravity` with the script.
+5. Trigger a request that is easy to identify, such as:
+   - Google sign-in
+   - model list loading
+   - quota refresh
+   - a generated request or prompt action
+
+### Why Manual Parameters Are Still Documented
+
+The script is the recommended default, but the raw parameters are still useful because:
+
+- contributors may want to understand exactly what the script configures
+- some people launch from VS Code, another shell, or a custom wrapper
+- some debugging sessions need a partial override rather than the full script
+
+### If Windows System Proxy Is Not Enough
+
+In some environments you may still need to point the system proxy to Proxyman manually. At minimum, verify:
+
+- HTTP proxy: `127.0.0.1:9090`
+- HTTPS proxy: `127.0.0.1:9090`
+- the bypass list is not excluding the domains you want to inspect
+
+### If You Need Direct Chromium Proxy Arguments
+
+If system proxy behavior is unreliable, you can launch the installed client with explicit Chromium proxy arguments:
+
+```powershell
+& "C:\Users\<YourUser>\AppData\Local\Programs\Antigravity\Antigravity.exe" `
+  --proxy-server="http://127.0.0.1:9090" `
+  --proxy-bypass-list="<local>;localhost;127.0.0.1;::1"
+```
+
+Use this as a fallback, not the default path.
+
+## Debug Gemini Nexus From This Repository
+
+This project has more layers than the official client. The script above is not the general launcher for this repository's development app.
+
+### Capture Main-Process, Node, and Internal Proxy Traffic
+
+Set proxy-related environment variables before starting the app:
+
+```powershell
+$env:HTTP_PROXY = "http://127.0.0.1:9090"
+$env:HTTPS_PROXY = "http://127.0.0.1:9090"
+$env:ALL_PROXY = "http://127.0.0.1:9090"
+$env:NO_PROXY = "localhost,127.0.0.1,::1"
+$env:NODE_EXTRA_CA_CERTS = "$env:APPDATA\\Proxyman\\certificate\\certs\\ca.pem"
+
+# Enable only for temporary TLS debugging
+$env:NODE_TLS_REJECT_UNAUTHORIZED = "0"
+
+npm start
+```
+
+This primarily affects:
+
+- Node HTTP and HTTPS requests
+- `undici`, `fetch`, and some dependency-driven upstream requests
+- internal proxy requests forwarded to upstream services
+
+### Also Capture Electron and Chromium Traffic
+
+If you want both Node-side and renderer-side traffic, add Chromium proxy arguments:
+
+```powershell
+$env:HTTP_PROXY = "http://127.0.0.1:9090"
+$env:HTTPS_PROXY = "http://127.0.0.1:9090"
+$env:ALL_PROXY = "http://127.0.0.1:9090"
+$env:NO_PROXY = "localhost,127.0.0.1,::1"
+$env:NODE_EXTRA_CA_CERTS = "$env:APPDATA\\Proxyman\\certificate\\certs\\ca.pem"
+$env:NODE_TLS_REJECT_UNAUTHORIZED = "0"
+
+npm start -- --proxy-server="http://127.0.0.1:9090" --proxy-bypass-list="<local>;localhost;127.0.0.1;::1"
+```
+
+If your local `npm start` flow does not forward arguments to Electron Forge, use one of these fallback approaches:
+
+- capture only Node and main-process traffic
+- wrap the Electron launch in your own PowerShell or VS Code task
+
+## Troubleshooting
+
+### I Can See Requests but HTTPS Bodies Are Empty
+
+Check:
+
+- the Proxyman root certificate is really trusted
+- `NODE_EXTRA_CA_CERTS` is set when Node-side traffic needs it
+- `NODE_TLS_REJECT_UNAUTHORIZED=0` is only being used as a temporary debugging override
+- the target app is not using SSL pinning
+
+Background setup guide:
+
+- [Proxyman Installation and Basic Setup on Windows](./proxyman-install.md)
+
+### I Can See Browser Traffic but Not Node or Main-Process Traffic
+
+Common causes:
+
+- Node is not using system proxy settings
+- the HTTP client does not read `HTTP_PROXY`
+- only the system proxy was configured, but runtime environment variables were not
+
+### I Cannot See `localhost` Traffic
+
+Common cause:
+
+- loopback traffic is bypassing the proxy
+
+Keep this bypass list in mind when launching Electron:
+
+```plaintext
+--proxy-bypass-list="<local>;localhost;127.0.0.1;::1"
+```
+
+Adjust it only if your current debugging target requires a different loopback behavior.
+
+### TLS Still Fails After the Certificate Was Installed
+
+Common causes:
+
+- the process started before the certificate was installed and needs a full restart
+- `ca.cer` was imported but `ca.pem` was not passed to Node when required
+- a corporate proxy, VPN, or security product is changing network behavior
+- the target app uses SSL pinning
+
+## Security Notes
+
+Keep local debugging settings out of the repository and out of public issue threads.
+
+- Do not commit your local proxy address, certificate paths, cookies, or OAuth codes.
+- Do not leave `NODE_TLS_REJECT_UNAUTHORIZED=0` enabled beyond temporary local debugging.
+- Do not post raw tokens, sessions, or authorization headers in public issues.
+- Redact logs before sharing them.
+
+## Minimal Workflows
+
+### Official Antigravity Client
+
+1. Complete [Proxyman Installation and Basic Setup on Windows](./proxyman-install.md).
+2. Open Proxyman.
+3. Run:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\start-antigravity-with-proxyman.ps1
+```
+
+4. Trigger login, quota, or model-list traffic.
+
+### Gemini Nexus in This Repository
+
+1. Complete [Proxyman Installation and Basic Setup on Windows](./proxyman-install.md).
+2. Open PowerShell.
+3. Set `HTTP_PROXY`, `HTTPS_PROXY`, and `NODE_EXTRA_CA_CERTS`.
+4. Run `npm start`.
+5. Filter Proxyman traffic by domains such as:
+   - `googleapis.com`
+   - `googleusercontent.com`
+   - the upstream domain you are debugging

+# Proxyman Installation and Basic Setup on Windows
+
+This guide covers the Proxyman prerequisites for contributors:
+
+1. Install Proxyman for Windows
+2. Trust the Proxyman certificate so HTTPS traffic can be decrypted
+3. Verify that Proxyman is working before you start debugging Antigravity traffic
+
+If your goal is to debug the installed Antigravity client or this repository's development build, continue with [Proxyman Debugging Guide](./proxyman-debugging.md).
+
+## Scope
+
+This document is intentionally limited to the setup layer. It does not cover Antigravity-specific debugging flows.
+
+Use it when you need to answer:
+
+- How do I install Proxyman on Windows?
+- How do I trust the certificate?
+- Why can I only see CONNECT requests but not HTTPS bodies?
+- How do I verify that Proxyman itself is working?
+
+## Install Proxyman
+
+Official resources:
+
+- Download: [https://proxyman.com/download](https://proxyman.com/download)
+- Windows product page: [https://proxyman.com/windows](https://proxyman.com/windows)
+
+Recommended steps:
+
+1. Install the Windows build from the official download page.
+2. Launch Proxyman.
+3. Confirm that Proxyman is listening on a local proxy port.
+4. This guide uses `9090` as the example port. Replace it with your local port if it differs.
+
+## Install and Trust the Certificate
+
+Without the Proxyman root certificate, you will usually only see CONNECT tunnels or TLS handshakes instead of decrypted HTTPS requests.
+
+Official references:
+
+- Windows certificate installation: [https://docs.proxyman.com/proxyman-windows/install-certificate](https://docs.proxyman.com/proxyman-windows/install-certificate)
+- SSL troubleshooting: [https://docs.proxyman.com/troubleshooting/get-ssl-error-from-https-request-and-response](https://docs.proxyman.com/troubleshooting/get-ssl-error-from-https-request-and-response)
+
+### Recommended Path: Install Automatically
+
+In Proxyman, run:
+
+```plaintext
+Certificate -> Install Certificate on this Windows...
+```
+
+Then:
+
+1. Choose `Install & Trust`
+2. Approve the administrator prompt
+
+According to the official documentation, Proxyman uses Windows `certutil` to import the root certificate into the trusted store.
+
+### Prepare a PEM File for Node and Electron
+
+Some Node.js and Electron traffic needs more than system trust. You may also need to point the runtime at the PEM file:
+
+```plaintext
+%APPDATA%\Proxyman\certificate\certs\ca.pem
+```
+
+If you only see `ca.cer` and not `ca.pem`, confirm that Proxyman has generated the PEM variant before moving on.
+
+## Verify That Proxyman Works
+
+Do this before trying to debug any application-specific flow.
+
+### Verify Browser Traffic
+
+1. Open Proxyman.
+2. Visit any HTTPS page in a browser, for example:
+
+```plaintext
+https://httpbin.org/get
+```
+
+3. Confirm that the request and response appear in Proxyman.
+
+### If You Cannot See Any Traffic
+
+Check these first:
+
+- Proxyman is actually listening on the expected port
+- Windows proxy settings are pointing to Proxyman
+- A VPN, endpoint security agent, or antivirus is not taking over proxy behavior
+- The certificate is trusted
+
+If localhost traffic is missing, see:
+
+- [https://docs.proxyman.com/troubleshooting/couldnt-see-any-request-from-localhost-server](https://docs.proxyman.com/troubleshooting/couldnt-see-any-request-from-localhost-server)
+
+The official page includes macOS-specific examples, but the localhost bypass concept is still relevant on Windows.
+
+## Basic Troubleshooting
+
+### HTTPS Bodies Are Missing
+
+Common causes:
+
+- The Proxyman root certificate is not actually trusted
+- The target process was already running before the certificate was installed
+- The application uses SSL pinning
+
+### Certificate Is Installed but TLS Still Fails
+
+Common causes:
+
+- You imported `ca.cer` but did not provide `ca.pem` to the runtime when needed
+- A corporate proxy, VPN, or security product is overriding the network path
+- The target application uses SSL pinning
+
+### Localhost Traffic Is Missing
+
+Common cause:
+
+- Local loopback traffic is bypassing the proxy
+
+Official reference:
+
+- [https://docs.proxyman.com/troubleshooting/couldnt-see-any-request-from-localhost-server](https://docs.proxyman.com/troubleshooting/couldnt-see-any-request-from-localhost-server)
+
+## Next Step
+
+Once Proxyman is installed, trusted, and verified, continue with:

 ## Summary

+Users running the manager in a WSL development environment need to interact with the actual Gemini Nexus instance running on Windows, as Gemini Nexus is a Windows application.
 
 ## Proposed Changes
 
 ### 1. Path Resolution (`src/utils/paths.ts`)
 
 * Implement `isWsl()` utility function.
-* In `getAppDataDir()`: If WSL, return the Windows AppData path (e.g., `/mnt/c/Users/<User>/AppData/Roaming/Antigravity`).
-* In `getAntigravityExecutablePath()`: If WSL, return the Windows executable path (e.g., `/mnt/c/Users/<User>/AppData/Local/Programs/Antigravity/Antigravity.exe`).
+* In `getAppDataDir()`: If WSL, return the Windows AppData path (e.g., `/mnt/c/Users/<User>/AppData/Roaming/GeminiNexus`).
+* In `getGeminiNexusExecutablePath()`: If WSL, return the Windows executable path (e.g., `/mnt/c/Users/<User>/AppData/Local/Programs/GeminiNexus/GeminiNexus.exe`).
 * **Challenge:** Determining the correct Windows username.
   * **Strategy:** Assume Windows username matches WSL username, or scan `/mnt/c/Users` for a likely candidate (excluding Public, Default, etc.).
 
 ### 2. Process Management (`src/ipc/process/handler.ts`)
 
-* In `isProcessRunning()`: If WSL, execute `tasklist.exe` (via `/mnt/c/Windows/System32/tasklist.exe`) to check for `Antigravity.exe`.
-* In `startAntigravity()`: If WSL, execute the Windows executable directly.
-* In `closeAntigravity()`: If WSL, use `taskkill.exe` (via `/mnt/c/Windows/System32/taskkill.exe`).
+* In `isProcessRunning()`: If WSL, execute `tasklist.exe` (via `/mnt/c/Windows/System32/tasklist.exe`) to check for `GeminiNexus.exe`.
+* In `startGeminiNexus()`: If WSL, execute the Windows executable directly.
+* In `closeGeminiNexus()`: If WSL, use `taskkill.exe` (via `/mnt/c/Windows/System32/taskkill.exe`).
 
 ## Acceptance Criteria

 ## Purpose
 
-Antigravity Manager is a comprehensive enhancement tool for Antigravity, designed to remove AI development resource limits. It not only solves the lack of native multi-account switching in Antigravity IDE, but also introduces enterprise-grade AI account pool management. By taking control of app configuration state and cloud API resources, it allows users to switch seamlessly between unlimited local accounts and cloud AI services for an effectively "unlimited" AI usage experience.
+Gemini Nexus is a comprehensive enhancement tool for Gemini Nexus, designed to remove AI development resource limits. It not only solves the lack of native multi-account switching in Gemini Nexus IDE, but also introduces enterprise-grade AI account pool management. By taking control of app configuration state and cloud API resources, it allows users to switch seamlessly between unlimited local accounts and cloud AI services for an effectively "unlimited" AI usage experience.
 
 **Core goals:**
 
-* **Local multi-account switching**: Seamlessly switch Antigravity IDE local user state while protecting data integrity (automatic backup).
+* **Local multi-account switching**: Seamlessly switch Gemini Nexus IDE local user state while protecting data integrity (automatic backup).
 * **AI resource pool management (new)**: Centrally manage account pools for Google Gemini, Claude 3.5, and similar services.
 * **Intelligent quota monitoring (new)**: Monitor API quota and health in real time with a visual dashboard.
 * **Automatic resource scheduling (new)**: Automatically switch to the best available account when the current one runs out of quota (token keepalive + polling).
