fix: handle null hostOptions when no active hosts exist

- Remove Alpine x-for template for xterm containers (async rendering bug)
- Add static #xterm-wrapper div, JS creates/removes container elements directly
- addTab() uses document.createElement + appendChild for instant DOM
- switchTab() toggles display:block/none, closeTab() removes from DOM
- Add console.log for WebSocket open/close/error debugging
- Terminal now connects on page load

+
+## 2. V1 Status — FROZEN 🧊
+
+| Aspek | Detail |
+|-------|--------|
+| Kode | Semua di `v1/` — cmd/, internal/, pkg/, test/ |
+| Build | `cd v1 && go build ./cmd/hostkeeper` |
+| Test | `cd v1 && go test ./...` — 105 tests passing |
+| Branch backup | `v1-snapshot` — snapshot sebelum dipindah ke subdirektori |
+| Aturan | **JANGAN** mengubah file di `v1/` |
+
+---
+
+## 3. V2 Architecture — HTMX (Keputusan Penting)
+
+**Hostkeeper V2 menggunakan GoFiber + HTMX, BUKAN React.**
+
+Alasan:
+- Developer lebih nyaman dengan Go daripada JavaScript
+- ~90% kode adalah Go + HTML template
+- Hanya ~410 baris JS yang diperlukan (xterm.js, clipboard, toggle)
+- Build lebih sederhana — tanpa Vite, npm, TypeScript, Webpack
+- Bisa berjalan di browser biasa tanpa Electron
+
+```
+┌───────────────────────────────────────────────────┐
+│  Browser / Electron WebView                       │
+│  ┌─────────────────────────────────────────────┐  │
+│  │  HTMX (14kb) + Alpine.js (15kb) + xterm.js  │  │
+│  │  ● HTMX: search, filter, modal, form, nav   │  │
+│  │  ● Alpine: client state (toast, toggle)     │  │
+│  │  ● xterm.js: terminal (halaman terminal)    │  │
+│  │  ● Vanilla JS: clipboard, toggle, utils     │  │

+```
+
+| Library | Ukuran | Fungsi |
+|---------|--------|--------|
+| HTMX | 14kb | HTML-over-HTTP interaktivitas |
+| Alpine.js | 15kb | Client state (modal, toast, tab) |
+| xterm.js | ~100kb | Terminal emulator (WAJIB) |
+| TailwindCSS v4 | ~27kb | Utility-first CSS |
+
+---
+
+## 4. V2 Status — Sprint 0—6 Complete
+
+### ✅ Sudah Selesai
+- Semua dokumentasi diupdate ke HTMX (10 file di `docs/`)
+- Template UI dianalisis (Lumina System — bright-tech glassmorphic, TailwindCSS v4)
+- Root dibersihkan — V1 di `v1/`, V2 siap dimulai di `app/`
+- `template/` tetap sebagai referensi desain (warna, layout, spacing)
+- Bug template sudah diidentifikasi (animasi CSS, w-4.5, error boundary, dll)
+- **Sprint 0**: GoFiber v2 server + HTMX + Alpine.js + TailwindCSS v4 + custom CSS + layout + nav + health endpoint
+- **Sprint 1**: Host model (8 mock hosts), dashboard CRUD, search/filter HTMX, grid/list Alpine toggle, add host modal (Alpine events), delete host (hx-delete), transfers panel
+- **Sprint 2**: Snippets + Keychain CRUD, clipboard.js, utils.js
+- **Sprint 3**: Settings + Brief, tabs, toggles, danger zone
+- **Sprint 4**: SFTP Dual-Pane, breadcrumb, file icons by type, create/delete
+- **Sprint 5**: Terminal + xterm.js + WebSocket mock shell, tab management
+- **Sprint 6**: JSON file persistence (store package), `go.mod replace` directive for V1 crypto+knownhosts, model SSH fields, real SSH client for terminal (falls back to mock), dynamic host list from server
+
+### 🐛 UI Fix Checklist — Lihat `docs/PERBAIKANUI.md`
+- **107 task** teridentifikasi dari audit visual vs template React
+- Acuan utama: 7 file di `template/src/components/`
+- Setiap task dihapus dari checklist setelah selesai
+- Urutan: Dashboard (P0) → Terminal (P0) → Snippets (P0) → Keychain/SFTP/Settings/Brief (P1)

+
+## 6. Yang Harus Dilakukan Selanjutnya (UI Fix)
+
+1. Baca `docs/PERBAIKANUI.md` — 107 task teridentifikasi
+2. Urutan: Dashboard (P0) → Terminal (P0) → Snippets (P0) → Keychain (P1) → SFTP (P1) → Settings (P1) → Brief (P1) → Global (P1)
+3. Setiap selesai satu task, hapus dari checklist `docs/PERBAIKANUI.md`
+4. Verify: `cd app/backend && go build && ./backend` lalu buka http://localhost:1947
+
+---
+
+## 7. Path Penting & Referensi
+
+| Untuk | Lihat di |
+|-------|----------|
+| Arsitektur HTMX lengkap | `docs/ARCHITECTURE_HTMX.md` |
+| API spec | `docs/API.md` |
+| Data models (Go struct) | `docs/DATA_MODELS.md` |
+| HTMX component tree | `docs/UI_COMPONENTS.md` |
+| Sprint plan detail | `docs/SPRINT_PLAN.md` |
+| Timeline 3.5 minggu | `docs/TIMELINE.md` |
+| Build system | `docs/BUILD_SYSTEM.md` |
+| Status tracker | `docs/PROGRESS.md` |
+| UI fix checklist | `docs/PERBAIKANUI.md` |
+| Template desain (React) | `template/AGENTS.md` (Lumina System) |
+| Template komponen (referensi) | `template/src/components/` |
+| V1 shared packages | `v1/pkg/ssh/`, `v1/pkg/crypto/`, `v1/pkg/storage/`, `v1/pkg/config/`, `v1/pkg/knownhosts/` |
+| V1 build & test | `cd v1 && go build ./cmd/hostkeeper && go test ./...` |
+
+---
+
+## 8. Aturan Penting
+
+- **JANGAN** mengubah file di `v1/` — V1 FROZEN
+- **JANGAN** mengubah `template/` — itu referensi desain, bukan source aktif
+- Semua kode V2 baru di `app/`
+- Saat reuse `v1/pkg/*`, pakai `go.mod replace` — jangan copy
+- Template React hanya untuk referensi visual (warna, layout, spacing)
+- Gunakan TailwindCSS v4 + custom CSS (Lumina System)
+- Pakai bahasa Indonesia untuk komunikasi dengan user (swanadiva)

+# Changelog
+
+## [Unreleased] — V2 Planning Complete (2026-06-29)
+
+### Added (V2 Planning Documents)
+- `docs/PROGRESS.md` — Status tracker for V2 development
+- `docs/ARCHITECTURE.md` — System architecture (GoFiber + React + Electron)
+- `docs/API.md` — REST API + WebSocket specification
+- `docs/DATA_MODELS.md` — Extended data models (Groups, PortForward, Workspace)
+- `docs/UI_COMPONENTS.md` — React component tree + state management
+- `docs/UI_TERMIUS_REFERENCE.md` — Termius visual reference
+- `docs/SPRINT_PLAN.md` — Sprint-by-sprint task breakdown
+- `docs/BUILD_SYSTEM.md` — Cross-platform build pipeline
+- `docs/PERFORMANCE.md` — Performance & stability guide
+
+### Architecture Decision
+- Backend: GoFiber v2 (fasthttp-based) replacing chi/net/http
+- WebSocket: gofiber/contrib/websocket (fasthttp/websocket) replacing gorilla/websocket
+- Frontend: React 19 + TypeScript + xterm.js + Zustand
+- Desktop: Electron (electron-builder)
+- Mobile: gomobile + WebView
+
+### V1 Status (FROZEN)
+- All V1 code (pkg/, internal/, cmd/, test/) is complete and frozen
+- V1 CLI/TUI remains functional alongside V2 GUI
+- 105 tests passing, zero race conditions
+
+## [Unreleased] — 2025-01-31
+
+### Fixed
+- TUI host list footer now includes `Ctrl+E:edit`
+- New hosts/keys/snippets created via TUI form now get UUID + timestamps (`CreatedAt`, `UpdatedAt`)
+- Storage layer auto-generates UUID + timestamps on save if empty (defense-in-depth)
+- **host_form_tab.go**: Space/Left/Right keys now passthrough to text input when not on auth type field (fixes typing spaces and cursor navigation)
+- **tui.go**: Key and snippet list tabs now properly refresh after save/delete (mirrors host flow)
+- **tabs.go**: WindowSizeMsg now forwarded to ALL tabs, not just the active one (fixes stale dimensions after resize)
+
+### Changed
+- All tab footers are now context-specific (no global status bar)
+- SFTP browser uses full-width panes (`t.width/2`)
+- **sftp_browser_tab.go footer**: Added `Enter/→:open`, `←/Backspace:up`
+- **form tabs footer**: Added `Shift+Tab:prev`, `↑↓:nav`
+
+### Responsive Layout (Done)
+- **NEW `responsive.go`**: Shared helpers (`wrapFooter`, `adaptiveSidePad`, `clampWidth`, `truncateStr`)
+- Footer auto-wraps to multi-line when terminal is narrow (full labels preserved)
+- Box width clamped to terminal width — no more overflow
+- Host/key/snippet rows truncated with `…` when names are too long; compact row format on narrow screens
+- SFTP panes stack vertically when terminal < 50 cols
+- Tab bar truncates tab names on overflow
+- Form contentW minimum lowered from 50 to 30 for mobile (Termux)
+- Fixed: key_list_tab & snippet_list_tab were dropping last data row (off-by-one in `rows[:len(rows)-1]`)
+- Fixed: SFTP pane width — lipgloss `Width(n)` renders `n+2` chars (border extra). halfW now `t.width/2-2` to compensate. File names truncate to `…` within inner text area. Filter line also truncated.
+- Verified: zero overflow at 80, 60, 50 (side-by-side), 40, 30 cols (stacked)
+
+### SFTP Stacked Mode Fix (Done)
+- Stacked mode (<50 cols) now renders only the active pane (Local or Remote)
+- Added pane indicator bar: `[Local]  Remote` with active pane highlighted
+- Side-by-side mode (≥50 cols) unchanged — both panes remain visible
+- Tab key now visually switches between panes on narrow terminals
+- Default active pane: Local (was Remote)
+- Border height fix: pane uses fixed `Height(maxH)` — border no longer shrinks/grows when scrolling
+- `renderPane` now takes `maxH` parameter to control content area height
+- Stacked: `maxH = t.height - 6`; Side-by-side: `maxH = t.height - 5`
+- Breakpoints: compact (<60), medium (60–100), wide (≥100)
+
+### SFTP Performance Fix
+- Added directory listing cache (`dirCache map[string][]os.FileInfo`) to each pane
+- Cache hit: instant navigation (no disk/network call)
+- Cache miss: read from disk/SFTP, store in cache
+- `R` key now clears cache for current directory and forces re-read
+- Cache is per-path: navigating to a previously visited folder is instant
+
+### SFTP File Transfer Progress Bar
+- Added progress bar during upload/download: `[████████░░░░] 67% 12.3MB/18.5MB`
+- `progressWriter` wraps `io.Writer` and reports bytes transferred
+- Footer shows live progress during transfer
+- Auto-refresh destination pane after transfer completes
+- Success message shown for 1 second before clearing
+
+### SFTP Auto-Refresh Fix
+- Added `program *tea.Program` field to SFTPBrowserTab and Model
+- `SetProgram()` method allows goroutines to send messages to Bubble Tea
+- After transfer: `t.program.Send(sftpRefreshMsg{})` triggers re-render
+- Model stores program reference, passes it to SFTP tab on creation
+
+### SFTP Bug Fixes
+- Auto-refresh: clear dirCache before refresh after transfer/delete/mkdir
+- Cache was stale after file operations — old entries returned instead of fresh
+- Filter mode: allow command keys (c, d, n, r) and navigation (↑↓, Tab) to pass through
+- Filter mode no longer blocks transfer, delete, mkdir, or pane switch
+- Delete: clear cache + trigger re-render after file removal
+- Mkdir: clear cache + trigger re-render after directory creation
+
+### SFTP Rename Feature
+- Added `M` key to rename files and directories
+- Rename mode: shows input with current name, type new name, Enter to confirm
+- Works on both Local and Remote panes
+- Clears cache and refreshes after rename
+- Footer updated: `M:rename` added
+- Filter mode allows `M` to pass through
+
+## v1.0.0 (2025-01-30)
+
+### Added
+
+- Initial release of Hostkeeper SSH/SFTP management tool
+- **Host management**: CRUD operations for SSH hosts (add, list, edit, delete)
+- **SSH connections**: Native SSH (default) and Go SSH direct mode
+- **TUI interface**: Interactive host browser using Bubble Tea
+- **Export/Import**: JSON export and import with merge/replace strategies
+- **Cross-platform builds**: Support for Linux, macOS, Windows, Termux
+- **Shell completion**: Bash, Zsh, Fish, and PowerShell support
+- **Configuration**: File-based credential storage with `0600` permissions
+- **Tag and group**: Host categorization with tags and groups
+- **Search and filter**: Filter hosts by group, tag, or text search
+
+### Commands
+
+- `hostkeeper add` — Add SSH hosts (interactive and flag-based)
+- `hostkeeper list` — List hosts with table/JSON output
+- `hostkeeper connect` — Connect to hosts with custom timeout
+- `hostkeeper edit` — Edit host configurations
+- `hostkeeper delete` — Delete hosts with confirmation
+- `hostkeeper export` — Export data to JSON
+- `hostkeeper import` — Import data with merge/replace
+- `hostkeeper tui` — Terminal user interface
+- `hostkeeper completion` — Shell completion generation
+- `hostkeeper version` — Version information
+
+### Technical
+
+- Cobra CLI framework for command structure
+- Bubble Tea TUI with keyboard navigation
+- Go SSH client for direct connections
+- Comprehensive test suite with unit and integration tests
+- Build automation via Makefile and build.sh
+
+### Notes
+
+- Initial MVP release, all core features functional
+- Encrypted storage planned for future release
+- Interactive shell in Go SSH direct mode not yet available
+
+## Phase 2 — Security Enhancement
+
+### AES-256-GCM Encryption
+- New `pkg/crypto/crypto.go`: AES-256-GCM encrypt/decrypt with PBKDF2 key derivation
+- 100,000 iterations, 16-byte salt, SHA-256 key derivation
+- `Encrypt(plaintext, password)` → base64(salt + nonce + ciphertext)
+- `Decrypt(encoded, password)` → plaintext
+- `IsEncrypted(data)` checks if data looks like encrypted content
+
+### Storage Layer Encryption
+- `JSONStorage` now has `password` field for master encryption key
+- `SetPassword()`, `GetPassword()`, `IsEncrypted()` methods
+- `readJSON()` auto-decrypts if password is set and data is encrypted
+- `replaceHosts/KeyPairs/Snippets()` auto-encrypt before writing
+- All existing CRUD operations transparently encrypt/decrypt
+
+### Known Hosts Verification
+- New `pkg/knownhosts/knownhosts.go`: TOFU (Trust-On-First-Use) model
+- `KnownHosts` manages `known_hosts` file (JSON format)
+- `Verify()` checks if host key matches stored key
+- `HostKeyCallback()` returns `cryptossh.HostKeyCallback` for SSH config
+- Warns on key mismatch (potential MITM attack)
+
+### SSH Client Security
+- `Client` now supports `hostKeyCallback` and `passphraseCallback`
+- `SetHostKeyCallback()` — replaces `InsecureIgnoreHostKey()`
+- `SetPassphraseCallback()` — prompts for passphrase on encrypted keys
+- `getKeySigner()` tries passphrase callback if key is encrypted
+
+### Models Updated
+- `AppConfig`: added `EncryptionEnabled`, `PasswordHash`, `KnownHostsFile`
+
+## Phase 2 UX Polish (Done)
+
+### Theme System
+- **NEW `themes.go`**: `Theme` struct with full color palette
+- 3 predefined themes: `dark` (Gruvbox), `light`, `dracula`
+- `SetTheme(name)` — updates all component styles at runtime
+- `GetActiveTheme()` — returns current theme
+- All palette vars now derived from active theme
+
+### Config Profiles
+- **`models.go`**: `Profile` struct — name, theme, default group, default auth, editor, notes
+- `AppConfig.Profiles []Profile` — list of named profiles
+- `AppConfig.ActiveProfile string` — currently active profile
+- `GetProfile(name)`, `GetActiveProfile()`, `AddProfile()`, `RemoveProfile()`
+- Default config includes "default" profile
+
+### Enhanced Error Display
+- **NEW `error_banner.go`**: `ErrorBanner` with severity levels (Error/Warning/Info)
+- Structured format: title + detail + numbered hints
+- Auto-dismiss after 5 seconds (configurable)
+- Color-coded: red (error), yellow (warning), blue (info)
+- `Show()`, `Hide()`, `Update()`, `View(width)` methods
+
+### Tests
+- **`test/tui/theme_test.go`**: GetTheme, SetTheme, GetActiveTheme, registry
+- **`test/tui/error_banner_test.go`**: Show/Hide, AutoDismiss, Severity, View
+- **`test/models_test.go`**: DefaultConfig, Profile CRUD
+
+## Phase 3 Testing (Done)
+
+### Security-Critical Tests (0% → 100%)
+- **`test/crypto/crypto_test.go`** (19 tests): DeriveKey, Encrypt/Decrypt round-trip, empty/large/unicode/newlines data, wrong/empty password, IsEncrypted, HashPassword, randomness
+- **`test/knownhosts/knownhosts_test.go`** (14 tests): New, Add/Get/Remove CRUD, Verify unknown/match/mismatch (MITM), HostKeyCallback autoAdd, persistence, corrupted file
+
+### Core Tests (40% → 90%)
+- **`test/storage/json_storage_test.go`** (20 tests): KeyPair CRUD (6), Snippet CRUD (6), encryption (SetPassword, IsDataEncrypted, wrong password), MergeStrategy (merge/replace), edge cases
+
+### Config Tests (22% → 80%)
+- **`test/config/config_test.go`** (9 tests): New first run, Save, UpdateAppConfig, path getters
+
+### UI Tests (40% → 70%)
+- **`test/tui/responsive_test.go`** (10 tests): WrapFooter, ClampWidth, TruncateStr
+
+### Bug Fixes
+- **knownhosts deadlock**: `Add()`/`Remove()` now call `saveInternal()` instead of `Save()` to avoid re-locking
+- **responsive.go**: Exported `WrapFooter`, `ClampWidth`, `TruncateStr` for testing
+
+### Coverage Summary
+- `pkg/crypto`: 0% → **100%** (19 tests)
+- `pkg/knownhosts`: 0% → **100%** (14 tests)
+- `pkg/storage`: 40% → **90%** (20 tests)
+- `pkg/config`: 22% → **80%** (9 tests)
+- `pkg/tui`: 40% → **70%** (10 new tests)
+- Total: **105 tests**, all passing, zero race conditions

+# Hostkeeper V2 — Architecture
+
+> **Status**: Migrasi React → HTMX
+> **Last Updated**: 2026-07-07
+> **Dokumen arsitektur baru**: [ARCHITECTURE_HTMX.md](ARCHITECTURE_HTMX.md)
+> **V1 (existing)**: CLI/TUI SSH/SFTP manager — frozen, no changes.
+
+---
+
+## ⚠️ Keputusan Arsitektur
+
+Hostkeeper V2 menggunakan **GoFiber + HTMX**, **bukan React/SPA**.
+
+Keputusan ini diambil karena:
+1. Developer lebih nyaman dengan Go daripada JavaScript
+2. ~90% kode adalah Go + HTML template
+3. Hanya ~410 baris JS yang diperlukan (xterm.js, clipboard, toggle)
+4. Build lebih sederhana — tanpa Vite, npm, TypeScript
+5. Bisa berjalan di browser biasa tanpa Electron
+
+**Dokumen arsitektur lengkap ada di** [`ARCHITECTURE_HTMX.md`](ARCHITECTURE_HTMX.md).

+
+## 4. Process Model
+
+### Startup Sequence
+
+```
+1. User double-clicks Hostkeeper.app (Electron)
+2. Electron main process starts
+3. Electron spawns Go binary as child process
+4. Go binary starts GoFiber server on localhost:randomPort
+5. Go serves frontend dist (embedded in Electron)
+6. Electron loads web UI from localhost:PORT
+7. Web UI renders vault unlock screen
+8. User enters password -> Go unlocks vault (decrypts data)
+9. User sees host list screen -> ready to use
+```
+
+### Shutdown Sequence
+
+```
+1. User closes window / Cmd+Q
+2. Electron sends SIGTERM to Go child process
+3. Go receives signal -> starts graceful shutdown
+4. Go disconnects all active SSH sessions
+5. Go saves any pending state
+6. Go closes fiber server
+7. Go exits
+8. Electron exits
+```
+
+### Development Mode
+
+```
+1. Terminal: cd app/backend && go run .
+2. Terminal: cd app/frontend && npm run dev
+3. Go server at localhost:8080
+4. Frontend dev server at localhost:5173 (Vite HMR)
+5. Frontend proxies API requests to localhost:8080
+6. Open browser at localhost:5173
+```
+
+---
+
+## 5. Data Flow
+
+### REST API Request Flow
+
+```
+React component
+  → useQuery/useMutation (React Query or manual fetch)
+    → API client (fetch wrapper)
+      → HTTP request to GoFiber (localhost:PORT/api/...)
+        → GoFiber router -> handler function
+          → Handler calls pkg/storage (read/write JSON)
+            → Response sent back through the chain
+```
+
+### Terminal WebSocket Flow
+
+```
+User opens terminal tab
+  → React: XTermWrapper mounts
+    → XTermWrapper opens WebSocket to ws://localhost:PORT/ws/terminal?host_id=xxx&cols=80&rows=24
+      → GoFiber WebSocket handler accepts connection
+        → Go: SSH client connects to remote host (reuse pkg/ssh)
+          → SSH session created, PTY requested
+            → SSH stdout goroutine -> reads SSH output -> c.WriteMessage(BinaryMessage, data)
+              -> xterm.js receives data -> renders in terminal
+            -> xterm.js onKey -> c.WriteMessage(BinaryMessage, input)
+              -> Go receives input -> session.Stdin.Write(input) -> SSH remote
+```
+
+### SFTP File Transfer Flow
+
+```
+User drags file to remote pane
+  → React: FileList onDrop handler
+    → API client: POST /api/sftp/upload (multipart/form-data)
+      → Go: bridge/sftp.go receives upload
+        → Go: pkg/sftp client writes to remote
+          → Response: { "success": true }
+            → React: refresh remote file list
+```
+
+---
+
+## 6. Security Architecture
+
+### Encryption Model
+
+| Layer | Method | Implementation |
+|-------|--------|----------------|
+| Data at rest | AES-256-GCM | `pkg/crypto/crypto.go` (reuse V1) |
+| Key derivation | PBKDF2 (100k iterations) | `pkg/crypto/crypto.go` (reuse V1) |
+| Password storage | SHA-256 hash | `pkg/config/config.go` (reuse V1) |
+| Known hosts | TOFU verification | `pkg/knownhosts/knownhosts.go` (reuse V1) |
+| Transport | localhost only | No TLS needed (same machine) |
+| Export | AES-256-GCM with password | `pkg/storage/json_storage.go` (reuse V1) |
+
+### Vault Flow
+
+```
+App start -> vault locked -> prompt password
+  -> PBKDF2 derive key from password
+    -> Try decrypt hosts.json
+      -> Success -> vault unlocked, data accessible
+      -> Fail -> wrong password, show error
+        -> Vault locked -> no data accessible
+          -> Auto-lock after inactivity timer
+```
+
+### OS Keychain Integration
+
+| Platform | Library | Purpose |
+|----------|---------|---------|
+| macOS | `security` CLI or `go-keychain` | Store vault master key |
+| Windows | `go-credential` | Store vault master key |
+| Linux | `dbus` Secret Service | Store vault master key |
+| Electron | `safeStorage` API | Store vault master key |
+
+---
+
+## 7. WebSocket Protocol
+
+### Terminal WebSocket
+
+**Connection**: `ws://localhost:PORT/ws/terminal?host_id=xxx&cols=80&rows=24`
+
+**Message types** (binary frames):
+
+| Direction | Type | Content |
+|-----------|------|---------|
+| Client → Server | Input | Raw keystroke bytes |
+| Server → Client | Output | Terminal output bytes |
+| Client → Server | Resize | JSON: `{ "type": "resize", "cols": 120, "rows": 40 }` |
+| Server → Client | Status | JSON: `{ "type": "status", "state": "connected" }` |
+| Server → Client | Error | JSON: `{ "type": "error", "message": "..." }` |
+
+**Keepalive**: Client sends ping every 30s, server responds with pong.
+
+---
+
+## 8. Build System
+
+### Development
+
+```bash
+# Terminal 1: Go backend
+cd app/backend
+go run .
+
+# Terminal 2: Frontend with hot reload
+cd app/frontend
+npm run dev
+
+# Browser opens at http://localhost:5173
+```
+
+### Production Build
+
+```bash
+# Full build
+./scripts/build.sh
+
+# Output:
+# dist/hostkeeper-mac-arm64.dmg
+# dist/hostkeeper-win-x64.exe
+# dist/hostkeeper-linux-x64.AppImage
+```
+
+### Cross-Compilation Matrix
+
+| Platform | GOOS | GOARCH | Output |
+|----------|------|--------|--------|
+| macOS ARM64 | darwin | arm64 | hostkeeper-mac-arm64 |
+| macOS x64 | darwin | amd64 | hostkeeper-mac-x64 |
+| Windows x64 | windows | amd64 | hostkeeper-win-x64.exe |
+| Linux x64 | linux | amd64 | hostkeeper-linux-x64 |
+| Linux ARM64 | linux | arm64 | hostkeeper-linux-arm64 |
+| Android ARM64 | android | arm64 | hostkeeper-android.aar |
+| iOS ARM64 | ios | arm64 | hostkeeper-ios.xcframework |
+
+---
+
+## 9. Error Handling
+
+### Go Backend Errors
+
+```go
+// All API errors follow this format:
+{
+    "error": "Human-readable error message",
+    "code": "MACHINE_READABLE_CODE",
+    "details": "Optional technical details"
+}
+
+// HTTP status codes:
+// 200 - Success
+// 201 - Created
+// 400 - Bad Request (validation error)
+// 401 - Unauthorized (vault locked)
+// 404 - Not Found
+// 409 - Conflict (duplicate)
+// 500 - Internal Server Error
+```
+
+### Frontend Error Handling
+
+- Network errors: automatic retry with exponential backoff (3 retries)
+- API errors: toast notification with error message
+- WebSocket errors: reconnect button in terminal, auto-reconnect 3 times
+- Validation errors: inline field-level error messages
+
+---
+
+## 10. Testing Strategy
+
+| Layer | Tool | Coverage Target |
+|-------|------|----------------|
+| Go unit tests | `go test` | 80%+ |
+| Go integration tests | `go test -tags=integration` | Key flows |
+| React unit tests | Vitest + React Testing Library | 70%+ |
+| React E2E tests | Playwright | Critical flows |
+| Manual testing | All platforms | Every sprint |
+
+### Test Commands
+
+```bash
+# Go backend tests
+cd app/backend && go test ./...
+
+# Frontend tests
+cd app/frontend && npm test
+
+# Full test suite
+make test

+# Hostkeeper V2 — Architecture (HTMX)
+
+> **Status**: Approved — Menggantikan arsitektur React sebelumnya
+> **Last Updated**: 2026-07-07
+> **Keputusan**: React → GoFiber + HTMX + Alpine.js + minimal JS
+
+---
+
+## 1. Arsitektur Baru
+
+Hostkeeper V2 menggunakan arsitektur **server-rendered HTML** dengan interaktivitas via HTMX, bukan SPA React.

+```
+
+---
+
+## 4. Komponen UI & State Management
+
+### 4.1 Navigasi (HTMX)
+
+Sidebar navigation menggunakan HTMX untuk swap halaman:
+
+```html
+<a href="/hosts"
+   hx-get="/hosts"
+   hx-target="#main-content"
+   hx-push-url="true"
+   class="nav-item {{if eq .View "hosts"}}active{{end}}">
+  {{svg "server"}}
+  <span>Hosts</span>
+</a>
+```
+
+### 4.2 State Client (Alpine.js)
+
+State yang butuh client-side reactivity:
+
+```html
+<!-- Toggle view mode -->
+<div x-data="{ view: 'grid' }">
+  <button @click="view = 'list'" :class="view === 'list' ? 'bg-primary text-white' : ''">
+    List
+  </button>
+  <div x-show="view === 'grid'" id="host-grid">
+    {{template "host_list" .}}
+  </div>
+</div>
+
+<!-- Modal -->
+<div x-data="{ open: false }">
+  <button @click="open = true">Add Host</button>
+  <div x-show="open" class="modal-backdrop">
+    <div @click.outside="open = false" class="modal-content">
+      <form hx-post="/hosts" hx-target="#host-list" @submit="open = false">
+        ...
+      </form>
+    </div>
+  </div>
+</div>
+
+<!-- Toast -->
+<div x-data="{ toast: '', show: false }"
+     x-init="$watch('show', v => v && setTimeout(() => show = false, 3000))"
+     x-show="show"
+     class="toast">
+  <span x-text="toast"></span>
+</div>
+```
+
+### 4.3 JS Murni (Vanilla)
+
+```javascript
+// clipboard.js — copy to clipboard
+function copyToClipboard(text) {
+  navigator.clipboard.writeText(text);
+  // trigger toast via Alpine
+  document.querySelector('[x-data]').__x.$data.toast = 'Copied!';
+  document.querySelector('[x-data]').__x.$data.show = true;
+}
+
+// toggles.js — custom toggle switch
+function toggleSwitch(el) {
+  const checked = el.getAttribute('aria-checked') === 'true';
+  el.setAttribute('aria-checked', !checked);
+  fetch(`/settings/toggle?key=${el.dataset.key}&val=${!checked}`, { method: 'POST' });
+}
+```
+
+---
+
+## 5. Data Models (Go Structs)
+
+Semua data model di `internal/model/`, mapping dari template React `types.ts`:
+
+```go
+// model/host.go
+type Host struct {
+    ID        string `json:"id"`
+    Name      string `json:"name"`
+    IP        string `json:"ip"`
+    OS        string `json:"os"`
+    Provider  string `json:"provider"`
+    Status    string `json:"status"`    // "active" | "offline"
+    LastSeen  string `json:"lastSeen"`
+    Type      string `json:"type"`      // "api" | "db" | "edge" | "web" | "desktop" | "server"
+}
+
+// model/snippet.go
+type Snippet struct {
+    ID          string   `json:"id"`
+    Title       string   `json:"title"`
+    Description string   `json:"description"`
+    Code        string   `json:"code"`
+    Tags        []string `json:"tags"`
+    Collection  string   `json:"collection"` // "favorites" | "recent" | "all"
+    UpdatedAt   string   `json:"updatedAt"`
+    Icon        string   `json:"icon"`
+}
+```
+
+Lihat `docs/DATA_MODELS.md` untuk definisi lengkap.

+## 6. HTMX Patterns yang Digunakan
+
+| Pattern | Contoh | Keterangan |
+|---------|--------|------------|
+| Search | `hx-get="/hosts?q=..." hx-trigger="keyup delay:200ms" hx-target="#host-list"` | Debounced search |
+| Filter | `hx-get="/hosts?filter=active" hx-target="#host-list"` | Tab filter |
+| Modal | Alpine `x-show` + `hx-post` | Form dalam modal |
+| Infinite scroll | `hx-get="/hosts?page=2" hx-trigger="revealed" hx-target="#host-list" hx-swap="beforeend"` | Load more |
+| Delete | `hx-delete="/hosts/123" hx-target="#host-card-123" hx-swap="delete" hx-confirm="Yakin?"` | Confirm + delete |
+| Toast | Alpine state + `hx-trigger="htmx:afterRequest"` dari response header `HX-Trigger: showToast` | Notifikasi |
+| Tab | Alpine `x-data` + `x-show` | Panel tab |

+## 7. Keuntungan HTMX Dibanding React
+
+| Aspek | React (sebelumnya) | HTMX (sekarang) |
+|-------|-------------------|-----------------|
+| Dependency JS | 10+ library (React, Zustand, dll) | 3 library (HTMX, Alpine, xterm) |
+| Baris JS | ~2.878 baris TS/JSX | ~410 baris vanilla JS |
+| Build step | Vite + TypeScript + npm | CSS build + copy static |
+| Bahasa dominan | 60% TS + 40% Go | 90% Go + 10% HTML/JS |
+| State management | Zustand store | Server-side (HTMX) + Alpine |
+| API layer | REST JSON + manual fetch | HTML partials langsung |
+| Electron | Wajib (SPA) | Opsional (bisa browser) |
+| Debugging | React DevTools | Browser DevTools (HTML langsung) |
+| Time to implement | ~6 minggu | ~4 minggu (estimasi) |
+
+---
+
+## 8. Cara Kerja: React → HTMX Mapping per Halaman
+
+### Dashboard (Host List)
+
+| React | HTMX |
+|-------|------|
+| `useState` searchQuery | `hx-get="/hosts?q={search}"` |

+| File click navigation | `hx-get="/sftp/ls?path={dir}" hx-push-url` |
+| Upload/download | `hx-post="/sftp/upload"` |
+| Toast | Alpine `x-data` + `setTimeout` |
+
+### Snippets
+
+| React | HTMX |
+|-------|------|
+| `useState` search/tag/collection | `hx-get="/snippets?q=&tag=&col="` |
+| `useState` copiedId | JS `copyToClipboard()` |
+| `useState` showAddForm | Alpine `x-show="open"` |
+| Copy | `onclick="copyToClipboard('code')"` |
+
+### Keychain
+
+| React | HTMX |
+|-------|------|
+| `useState` search | `hx-get="/keys?q=..."` |
+| `useState` revealPassId | Alpine `x-data="{ reveal: false }"` |
+| `useState` copiedId | JS `copyToClipboard()` |
+| Strength badge | Go template: `{{if gt (len .Passphrase) 12}}secure{{end}}` |
+
+### Settings
+
+| React | HTMX |
+|-------|------|
+| Form state | HTML `<form>` + `hx-post="/settings"` |
+| Toggle switches | JS click handler + `fetch POST /settings/toggle` |
+| Danger zone | `onclick="localStorage.clear(); location.reload()"` |
+
+### Brief Overlay
+
+| React | HTMX |
+|-------|------|
+| `isOpen` + `onClose` | Alpine `x-show="open"` + `@click="open = false"` |
+| Konten statis | Go template render (HTML murni) |

+# Hostkeeper V2 — Build System
+
+> **Status**: Updated untuk HTMX
+> **Last Updated**: 2026-07-07
+> **Frontend**: Go HTML template + HTMX + TailwindCSS v4 (tanpa Vite/npm/React)
+
+---
+
+## 1. Build Overview
+
+Hostkeeper V2 adalah **single Go binary** yang melayani HTML + static files.
+
+| Platform | Output | Wrapper | Backend |
+|----------|--------|---------|---------|
+| macOS (ARM64) | `.dmg` | Electron (opsional) | Go binary |
+| macOS (x64) | `.dmg` | Electron (opsional) | Go binary |
+| Windows (x64) | `.exe` installer | Electron (opsional) | Go binary |
+| Linux (x64) | `.AppImage` | Electron (opsional) | Go binary |
+| Android (ARM64) | `.aab` | WebView | Go library (.aar) |
+| iOS (ARM64) | `.ipa` | WKWebView | Go framework (.xcframework) |
+
+**Catatan**: Tanpa Electron app tetap bisa jalan — tinggal buka `http://localhost:1947` di browser.

+# Hostkeeper V2 — Extended Data Models
+
+> **Status**: V2 Planning Complete
+> **Last Updated**: 2026-06-29
+> **V1 models**: `internal/models/models.go` — frozen, no changes.
+
+---
+
+## 1. Overview
+
+V2 extends V1 models with new entities for groups, vault, port forwarding, workspaces, and sessions. All V1 models remain unchanged. New models are added in `app/backend/models/` (or `internal/models/` with backward-compatible additions).
+
+---
+
+## 2. V1 Models (FROZEN — do not modify)
+
+These exist in `internal/models/models.go` and are used as-is:
+
+- `Host` — SSH host connection configuration
+- `AuthConfig` — Authentication configuration (password/key/agent)
+- `KeyPair` — SSH key pair
+- `Snippet` — Command snippet
+- `Profile` — Named configuration profile
+- `AppConfig` — Application configuration
+- `KnownHost` — Verified host key
+
+---
+
+## 3. V2 Models (NEW)
+
+### 3.1 HostGroup
+
+Nestable group for organizing hosts. Groups can contain other groups and hosts.
+
+```go
+type HostGroup struct {
+    ID          string       `json:"id" bson:"_id,omitempty"`
+    Name        string       `json:"name"`
+    ParentID    *string      `json:"parent_id,omitempty"` // nil = root group
+    Color       string       `json:"color,omitempty"`     // hex color e.g. "#e78a4e"
+    Icon        string       `json:"icon,omitempty"`      // icon name e.g. "server", "globe"
+    Order       int          `json:"order"`               // sort order within parent
+    Children    []*HostGroup `json:"children,omitempty"`  // populated at runtime, not stored
+    HostCount   int          `json:"host_count,omitempty"` // populated at runtime
+    CreatedAt   time.Time    `json:"created_at"`
+    UpdatedAt   time.Time    `json:"updated_at"`
+}
+```
+
+**Storage**: `groups.json`
+```json
+{
+    "groups": [
+        {
+            "id": "550e8400-e29b-41d4-a716-446655440000",
+            "name": "Production",
+            "parent_id": null,
+            "color": "#e78a4e",
+            "icon": "server",
+            "order": 0,
+            "created_at": "2024-06-22T10:00:00Z",
+            "updated_at": "2024-06-22T10:00:00Z"
+        }
+    ]
+}
+```
+
+**Rules**:
+- Maximum nesting depth: 5 levels
+- Root groups have `parent_id: null`
+- Deleting a group moves its hosts to parent (or ungrouped)
+- Group names must be unique within the same parent
+
+---
+
+### 3.2 Extended Host
+
+New fields added to the existing `Host` struct:
+
+```go
+// V2 additions to Host struct
+type HostV2 struct {
+    // ... all V1 fields ...
+    
+    GroupID      *string  `json:"group_id,omitempty"`      // reference to HostGroup.ID
+    IsFavorite   bool     `json:"is_favorite"`             // quick access
+    Color        string   `json:"color,omitempty"`         // override group color
+    Order        int      `json:"order"`                   // sort order within group
+    StartupSnippets []string `json:"startup_snippets,omitempty"` // snippet IDs to run on connect
+    Proxy        *ProxyConfig `json:"proxy,omitempty"`     // proxy configuration
+    JumpHost     *string  `json:"jump_host_id,omitempty"`  // jump host ID
+    Keepalive    int      `json:"keepalive,omitempty"`     // keepalive interval in seconds
+}
+```
+
+**Note**: V1 Host fields are untouched. V2 fields are added with `omitempty` for backward compatibility.
+
+---
+
+### 3.3 ProxyConfig
+
+Proxy configuration for SSH connections through proxy servers.
+
+```go
+type ProxyConfig struct {
+    Type     string `json:"type"`      // "socks5", "http", "command"
+    Host     string `json:"host"`      // proxy host
+    Port     int    `json:"port"`      // proxy port
+    Username string `json:"username,omitempty"`
+    Password string `json:"password,omitempty"`
+    Command  string `json:"command,omitempty"` // for "command" type (netcat-style)
+}
+```
+
+---
+
+### 3.4 PortForward
+
+SSH port forwarding configuration.
+
+```go
+type PortForward struct {
+    ID          string    `json:"id" bson:"_id,omitempty"`
+    Name        string    `json:"name"`
+    HostID      string    `json:"host_id"`                  // reference to Host.ID
+    Type        string    `json:"type"`                     // "local", "remote", "dynamic"
+    LocalAddr   string    `json:"local_addr"`               // e.g. "127.0.0.1:8080"
+    RemoteAddr  string    `json:"remote_addr"`              // e.g. "localhost:3000"
+    Status      string    `json:"status"`                   // "stopped", "running", "error"
+    AutoStart   bool      `json:"auto_start"`               // start tunnel on app launch
+    CreatedAt   time.Time `json:"created_at"`
+    UpdatedAt   time.Time `json:"updated_at"`
+}
+```
+
+**Storage**: `forwards.json`
+```json
+{
+    "forwards": [
+        {
+            "id": "forward-uuid",
+            "name": "Local Redis",
+            "host_id": "host-uuid",

+        }
+    ]
+}
+```
+
+**Forward Types**:
+- **Local**: `ssh -L localPort:remoteHost:remotePort` — forward local port to remote
+- **Remote**: `ssh -R remotePort:localHost:localPort` — forward remote port to local
+- **Dynamic**: `ssh -D localPort` — SOCKS5 proxy through SSH

+## 6. Migration from V1
+
+V2 data is backward-compatible with V1. New fields are optional (`omitempty`).
+
+**Migration steps** (automatic on first V2 launch):
+1. Read existing `hosts.json` — V2 fields default to zero values
+2. Create `groups.json` if not exists — empty groups
+3. Create `forwards.json` if not exists — empty forwards
+4. Create `workspaces.json` if not exists — empty workspaces
+5. Update `config.json` — add V2 config fields
+
+**No data loss**: V1 data is preserved. V2 fields are additive.

+
+## 2. Go Backend Performance
+
+### 2.1 GoFiber Configuration
+
+```go
+app := fiber.New(fiber.Config{
+    // Timeouts (prevent hung connections)
+    ReadTimeout:  30 * time.Second,
+    WriteTimeout: 30 * time.Second,
+    IdleTimeout:  120 * time.Second,
+    
+    // Concurrency (limit goroutines)
+    Concurrency: 256,
+    
+    // Body limit (prevent large payload attacks)
+    BodyLimit: 10 * 1024 * 1024, // 10MB
+    
+    // Buffer sizes (optimize for typical requests)
+    ReadBufferSize:  4096,
+    WriteBufferSize: 4096,
+    
+    // Disable startup banner
+    DisableStartupMessage: false,
+    
+    // JSON encoder (fastest)
+    JSONEncoder: json.Marshal,
+    JSONDecoder: json.Unmarshal,
+})
+```
+
+### 2.2 Connection Pooling (SSH)
+
+```go
+// app/backend/ws/pool.go
+type SessionPool struct {

+            delete(p.sessions, key)
+        }
+    }
+}
+```
+
+### 2.3 Buffer Pooling
+
+```go
+// app/backend/ws/buffers.go
+var bufferPool = sync.Pool{
+    New: func() interface{} {
+        buf := make([]byte, 4096)
+        return &buf
+    },
+}
+
+func GetBuffer() *[]byte {
+    return bufferPool.Get().(*[]byte)
+}
+
+func PutBuffer(buf *[]byte) {
+    // Reset buffer
+    (*buf) = (*buf)[:0]
+    bufferPool.Put(buf)
+}
+```
+
+### 2.4 Goroutine Management
+
+```go
+// Limit concurrent SSH sessions
+var sshSemaphore = make(chan struct{}, 50) // max 50 concurrent sessions
+
+func handleTerminal(c *websocket.Conn) {
+    // Acquire semaphore
+    select {
+    case sshSemaphore <- struct{}{}:
+        defer func() { <-sshSemaphore }()
+    default:
+        c.WriteJSON(fiber.Map{
+            "type":    "error",
+            "message": "Too many connections",
+        })
+        return
+    }
+    
+    // ... handle session
+}
+```
+
+---
+
+## 3. Frontend Performance
+
+### 3.1 Code Splitting (Lazy Loading)
+
+```typescript
+// app/frontend/src/router.tsx
+import { lazy, Suspense } from 'react';
+
+const HostListScreen = lazy(() => import('./screens/HostListScreen'));
+const TerminalScreen = lazy(() => import('./screens/TerminalScreen'));
+const SFTPScreen = lazy(() => import('./screens/SFTPScreen'));
+const SettingsScreen = lazy(() => import('./screens/SettingsScreen'));
+
+const router = createBrowserRouter([
+    {
+        path: '/',
+        element: <MainLayout />,
+        children: [
+            {
+                index: true,
+                element: (
+                    <Suspense fallback={<LoadingSpinner />}>
+                        <HostListScreen />
+                    </Suspense>
+                ),
+            },
+            // ... other routes
+        ],
+    },
+]);
+```
+
+### 3.2 Virtual Scrolling (Host List)
+
+```typescript
+// app/frontend/src/components/VirtualList.tsx
+import { useVirtualizer } from '@tanstack/react-virtual';
+
+interface VirtualListProps<T> {
+    items: T[];
+    renderItem: (item: T) => React.ReactNode;
+    estimateSize?: number;
+}
+
+function VirtualList<T>({ items, renderItem, estimateSize = 48 }: VirtualListProps<T>) {
+    const parentRef = useRef<HTMLDivElement>(null);
+    
+    const virtualizer = useVirtualizer({
+        count: items.length,
+        getScrollElement: () => parentRef.current,
+        estimateSize: () => estimateSize,
+        overscan: 10, // Render 10 items outside viewport
+    });
+    
+    return (
+        <div ref={parentRef} className="h-full overflow-auto">
+            <div style={{ height: virtualizer.getTotalSize() }}>
+                {virtualizer.getVirtualItems().map(virtualRow => (
+                    <div
+                        key={virtualRow.key}
+                        style={{
+                            position: 'absolute',
+                            top: virtualRow.start,
+                            height: virtualRow.size,
+                            width: '100%',
+                        }}
+                    >
+                        {renderItem(items[virtualRow.index])}
+                    </div>
+                ))}
+            </div>
+        </div>
+    );
+}
+```
+
+### 3.3 React.memo for Expensive Components
+
+```typescript
+// Prevent re-render when props haven't changed
+const HostItem = React.memo(function HostItem({ host, isActive, onClick }: HostItemProps) {
+    return (
+        <div onClick={onClick}>
+            {/* ... */}
+        </div>
+    );
+}, (prev, next) => {
+    return prev.host.id === next.host.id
+        && prev.isActive === next.isActive;
+});
+```
+
+### 3.4 useMemo for Expensive Computations
+
+```typescript
+function HostList({ hosts, filter }: { hosts: Host[]; filter: string }) {
+    const filteredHosts = useMemo(() => {
+        if (!filter) return hosts;
+        return hosts.filter(h =>
+            h.name.toLowerCase().includes(filter.toLowerCase()) ||
+            h.hostname.toLowerCase().includes(filter.toLowerCase())
+        );
+    }, [hosts, filter]);
+    
+    return <VirtualList items={filteredHosts} renderItem={renderHostItem} />;
+}
+```
+
+### 3.5 useCallback for Event Handlers
+
+```typescript
+function HostItem({ host, onSelect }: { host: Host; onSelect: (id: string) => void }) {
+    const handleClick = useCallback(() => {
+        onSelect(host.id);
+    }, [host.id, onSelect]);
+    
+    return <div onClick={handleClick}>{/* ... */}</div>;
+}
+```
+
+### 3.6 Zustand Selector Optimization
+
+```typescript
+// Bad: re-renders on ANY store change
+const hosts = useHostStore(state => state.hosts);
+
+// Good: only re-renders when hosts change
+const hosts = useHostStore(state => state.hosts);
+
+// Good: only re-renders when selectedHost changes
+const selectedId = useHostStore(state => state.selectedHost);
+
+// Good: granular selector
+const hostName = useHostStore(state => {
+    const host = state.hosts.find(h => h.id === state.selectedHost);
+    return host?.name;
+});
+```
+

+
+## 4. WebSocket Stability
+
+### 4.1 Keepalive
+
+```typescript
+// Client side (React)
+class TerminalWebSocket {
+    private ws: WebSocket;
+    private pingInterval: NodeJS.Timeout;
+    
+    connect(url: string) {
+        this.ws = new WebSocket(url);
+        
+        // Send ping every 30 seconds
+        this.pingInterval = setInterval(() => {
+            if (this.ws.readyState === WebSocket.OPEN) {
+                this.ws.send(new Uint8Array([0])); // ping frame
+            }
+        }, 30000);
+    }
+    
+    disconnect() {
+        clearInterval(this.pingInterval);
+        this.ws.close(1000, 'Client closing');
+    }
+}
+```
+
+```go
+// Server side (Go)
+func handleTerminal(c *websocket.Conn) {
+    // Set pong handler
+    c.SetPongHandler(func(string) error {
+        c.SetReadDeadline(time.Now().Add(60 * time.Second))
+        return nil
+    })
+    
+    // Read loop (detects disconnect)
+    for {
+        _, _, err := c.ReadMessage()
+        if err != nil {
+            break
+        }
+    }
+}
+```
+
+### 4.2 Auto-Reconnect
+
+```typescript
+// app/frontend/src/hooks/useTerminalReconnect.ts
+function useTerminalReconnect(ws: TerminalWebSocket) {
+    const [reconnectAttempts, setReconnectAttempts] = useState(0);
+    const maxReconnectAttempts = 5;
+    
+    useEffect(() => {
+        if (ws.status === 'disconnected' && reconnectAttempts < maxReconnectAttempts) {
+            const delay = Math.min(1000 * Math.pow(2, reconnectAttempts), 30000);
+            
+            const timer = setTimeout(() => {
+                setReconnectAttempts(prev => prev + 1);
+                ws.reconnect();
+            }, delay);
+            
+            return () => clearTimeout(timer);
+        }
+    }, [ws.status, reconnectAttempts]);
+    
+    return { reconnectAttempts, maxReconnectAttempts };
+}
+```
+
+### 4.3 Error Boundaries
+
+```typescript
+// app/frontend/src/components/ErrorBoundary.tsx
+class ErrorBoundary extends React.Component {
+    state = { hasError: false, error: null };
+    
+    static getDerivedStateFromError(error: Error) {

+
+## 5. Memory Management
+
+### 5.1 Terminal Cleanup
+
+```typescript
+function XTermWrapper({ tabId }: { tabId: string }) {
+    useEffect(() => {
+        const term = new Terminal({
+            scrollback: 10000, // Limit scrollback buffer
+        });
+        
+        return () => {
+            term.dispose(); // Free memory on unmount
+        };
+    }, []);
+}
+```
+
+### 5.2 WebSocket Cleanup
+
+```typescript
+useEffect(() => {
+    const ws = new WebSocket(url);
+    
+    return () => {
+        ws.close(); // Close on unmount
+    };
+}, [hostId]);
+```
+
+### 5.3 Image/Icon Lazy Loading
+
+```typescript
+// Only load icons when needed
+const Icon = lazy(() => import('./Icon'));
+
+// Or use intersection observer
+function LazyIcon({ name }: { name: string }) {
+    const [loaded, setLoaded] = useState(false);
+    const ref = useRef<HTMLDivElement>(null);
+    
+    useEffect(() => {
+        const observer = new IntersectionObserver(([entry]) => {
+            if (entry.isIntersecting) {
+                setLoaded(true);
+                observer.disconnect();
+            }
+        });
+        
+        if (ref.current) observer.observe(ref.current);
+        return () => observer.disconnect();
+    }, []);
+    
+    return <div ref={ref}>{loaded && <Icon name={name} />}</div>;
+}
+```

+
+## 6. Crash Recovery
+
+### 6.1 Go Panic Recovery
+
+```go
+// Already built into GoFiber
+app.Use(recover.New())
+
+// Custom panic handler
+app.Use(recover.New(recover.Config{
+    Handler: func(c *fiber.Ctx, err error) {
+        log.Printf("PANIC: %v\n%s", err, debug.Stack())
+        c.Status(500).JSON(fiber.Map{
+            "error": "Internal server error",
+            "code":  "PANIC",
+        })
+    },
+}))
+```
+
+### 6.2 Electron Crash Reporter
+
+```typescript
+// app/electron/main.ts
+import { crashReporter } from 'electron';
+
+crashReporter.start({
+    productName: 'Hostkeeper',
+    submitURL: '', // No remote reporting (privacy)
+    uploadToServer: false,
+    compress: true,
+});
+```
+
+### 6.3 State Persistence
+
+```typescript
+// Save critical state to localStorage
+window.addEventListener('beforeunload', () => {
+    const state = {
+        sidebarWidth: useUIStore.getState().sidebarWidth,
+        activeTab: useTabStore.getState().activeTab,
+        theme: useUIStore.getState().theme,
+    };
+    localStorage.setItem('hostkeeper-ui-state', JSON.stringify(state));
+});
+
+// Restore on load
+const savedState = localStorage.getItem('hostkeeper-ui-state');
+if (savedState) {
+    const state = JSON.parse(savedState);
+    useUIStore.getState().setSidebarWidth(state.sidebarWidth);
+    useUIStore.getState().setTheme(state.theme);
+}
+```
+
+---
+
+## 7. Logging
+
+### 7.1 Structured Logging (Go)
+
+```go
+import "github.com/gofiber/fiber/v2/log"
+
+// Request logging (built into GoFiber)
+app.Use(logger.New(logger.Config{
+    Format: "${time} ${method} ${path} ${status} ${latency}\n",
+    Done: func(c *fiber.Ctx, log string) {
+        // Custom log processing
+        if c.Response().StatusCode() >= 500 {
+            log.Error(log)
+        }
+    },
+}))
+
+// Application logging
+log.Info("Server started on port", port)
+log.Warn("Connection pool full")
+log.Error("SSH connection failed", err)
+```
+
+### 7.2 Frontend Logging
+
+```typescript
+// Only log in development
+const logger = {
+    info: (...args: any[]) => {
+        if (import.meta.env.DEV) console.log('[INFO]', ...args);
+    },
+    warn: (...args: any[]) => {
+        if (import.meta.env.DEV) console.warn('[WARN]', ...args);
+    },
+    error: (...args: any[]) => {
+        console.error('[ERROR]', ...args); // Always log errors
+    },
+};
+```
+
+---
+
+## 8. Monitoring
+
+### 8.1 Health Check Endpoint
+
+```go
+app.Get("/api/health", func(c *fiber.Ctx) error {
+    return c.JSON(fiber.Map{
+        "status":       "ok",
+        "version":      version,
+        "uptime":       time.Since(startTime).Seconds(),
+        "connections":  sessionPool.ActiveCount(),
+        "memory":       getMemoryUsage(),
+    })
+})
+```
+
+### 8.2 Metrics (Optional)
+
+```go
+// Simple metrics middleware
+var (
+    requestCount   = prometheus.NewCounter("requests_total")
+    requestLatency = prometheus.NewHistogram("request_latency_seconds")
+)
+
+app.Use(func(c *fiber.Ctx) error {
+    start := time.Now()
+    err := c.Next()
+    duration := time.Since(start).Seconds()
+    
+    requestCount.Inc()
+    requestLatency.Observe(duration)
+    
+    return err
+})
+```
+
+---
+
+## 9. Testing for Performance
+
+### 9.1 Load Testing (Go)
+
+```bash
+# Install hey (HTTP load testing)
+go install github.com/rakyll/hey@latest
+
+# Test API endpoints
+hey -n 1000 -c 50 http://localhost:8080/api/hosts
+hey -n 1000 -c 50 http://localhost:8080/api/keys
+hey -n 1000 -c 50 http://localhost:8080/api/snippets
+```
+
+### 9.2 Terminal Latency Test
+
+```typescript
+// Measure keystroke to display latency
+function measureTerminalLatency(term: Terminal): number {
+    const start = performance.now();
+    term.write('x'); // Write character
+    // Measure time until character is rendered
+    return performance.now() - start;
+}
+```
+
+### 9.3 Memory Profiling
+
+```go
+import "runtime"
+
+// Log memory usage
+var memStats runtime.MemStats
+runtime.ReadMemStats(&memStats)
+log.Printf("Memory: %d MB allocated, %d MB sys",
+    memStats.Alloc/1024/1024,
+    memStats.Sys/1024/1024,
+)
+```
+
+---
+
+## 10. Common Performance Pitfalls
+
+| Issue | Symptom | Fix |
+|-------|---------|-----|
+| Memory leak in terminals | Memory grows over time | Dispose terminals on unmount |
+| WebSocket not closing | Connections pile up | Close on component unmount |
+| Large JSON responses | Slow API | Pagination, field filtering |
+| No connection pooling | Slow SSH reconnect | Use SessionPool |
+| Synchronous SFTP | UI freezes | Use goroutines + channels |
+| Re-render storms | Jank, low FPS | React.memo, useMemo, Zustand selectors |
+| No code splitting | Slow initial load | Lazy load screens |
+| Oversized bundles | Slow startup | Tree shaking, purging |

+
+## 6. How to Continue
+
+### For a new AI agent:
+
+All Sprint 0—6 tasks for HTMX are **complete**. The V2 backend is fully functional with:
+- GoFiber v2 server on `:1947`
+- HTMX + Alpine.js for interactivity
+- JSON file persistence in `~/Library/Application Support/hostkeeper/v2/`
+- Real SSH terminal (with mock fallback)
+- All CRUD operations for hosts, snippets, keychain, settings
+
+Future work areas (beyond Sprint 6):
+- **Real SFTP**: Connect SFTP dual-pane to real SSH via `github.com/pkg/sftp`
+- **Mobile wrapper**: `gomobile` + WebView
+- **Electron wrapper**: Wrap in Electron for standalone desktop app
+- **Tests**: Write Go unit/integration tests for handlers and store
+- **CI/CD**: GitHub Actions for build + test
+- **Encryption**: Wire up `v1/pkg/crypto` to encrypt stored data
+- **Known Hosts**: Integrate `v1/pkg/knownhosts` for SSH host key verification
+
+### For a returning AI agent:
+
+1. **Read this file** — check "Last Session Notes" for context
+2. **Check git log** — `git log --oneline -10`
+3. **All Sprint items are `[x]`** — pick from "Future work areas" above
+4. **Update this file** when done

+# Hostkeeper V2 — Termius UI Reference
+
+> **Status**: V2 Planning Complete
+> **Last Updated**: 2026-06-29
+> **Purpose**: Visual reference for replicating Termius-like UI in Hostkeeper V2.
+
+---
+
+## 1. Termius Design Analysis
+
+### Design Philosophy
+
+Termius follows a **dark-first, minimal, professional** design language:
+- Dark backgrounds with muted colors
+- High contrast for active elements
+- Subtle hover states (no harsh highlights)
+- Generous padding and whitespace
+- Rounded corners (subtle, not bubbly)
+- Consistent iconography (Feather-style line icons)
+
+### Key Design Principles
+
+1. **Content-first** — Terminal/SFTP content takes maximum space
+2. **Sidebar minimal** — Thin sidebar, collapsible, icons + labels
+3. **Tab bar compact** — Small tab height, status dots, close buttons
+4. **Forms clean** — Labeled inputs, generous spacing, clear validation
+5. **Modals focused** — Centered, focused, one task at a time
+
+---
+

+# HostKeeper | Developer & AI System Brief
+
+> **MANDATORY INSTRUCTION FOR DOWNSTREAM AI AGENTS:**
+> Before proposing or implementing any changes, code edits, or new features in this workspace, you **MUST** read this instruction set fully. Every visual and architectural decision must align strictly with the rules defined below.
+
+---
+
+## 1. Visual Identity & Design System (Lumina System)
+
+Unlike standard, heavy, dark-themed hacker dashboards, HostKeeper uses the **Lumina System**—a premium, "bright-tech" glassmorphic developer workspace featuring clean off-whites, slate cards, vibrant accent highlights, and a high-clarity layout.
+
+### A. Color Palette
+Maintain the exact CSS variables and color definitions declared in `/src/index.css`:
+*   **Primary (Lumina Blue):** `#0050cb` (Focus boundaries, active selections, primary indicators)
+*   **Secondary (Neon Green):** `#006e2f` (Active/Online indicators, progress bars, successful transactions)
+*   **Tertiary (Tech Purple):** `#7e23cc` (File directories, custom command responses, highlight badges)
+*   **Surface Base Background:** `#f7f9fb`
+*   **Containers & Cards Lowest:** `#ffffff` (High-contrast pure white cards for depth separation)
+*   **Text/On-Surface Dark Slate:** `#191c1e` (Main UI text)
+*   **Subtle Labels/On-Surface Variant:** `#424656`
+
+### B. Grid, Depth & Glassmorphic Accents
+*   **Dot Grid Texture:** The background uses a responsive 16px repeating radial dot pattern:
+    `radial-gradient(#e2e8f0 1.5px, transparent 1.5px)` with a size of `16px 16px`.
+*   **Frosted Glass Sidebars & Overlays:** Use `backdrop-blur-md` and semi-transparent white backgrounds (`rgba(255, 255, 255, 0.7)`) to show subtle grid depth underneath overlays.
+*   **Elevation & Shadows:** Focus containers should never have heavy dark borders. Instead, apply thin borders (`border-outline-variant/30`) paired with subtle, color-matched glow shadows (`shadow-primary/10`).
+
+### C. Typography Pairing
+*   **Interface UI Font:** **Inter** (weights `300` to `900`). Used for titles, descriptive labels, tables, navigation buttons, and settings forms.
+*   **Technical / Data Font:** **JetBrains Mono** (weights `300` to `700`). Used exclusively for file paths, IP addresses, terminal prompt commands, and cataloged snippet blocks.
+
+---
+
+## 2. File & Component Architecture
+
+Keep the project highly modular. Do not merge separate view components into a single file to avoid hitting token limit cutoffs.
+
+*   `/src/types.ts`: Holds shared global interfaces (e.g., `Host`, `FileItem`, `Snippet`, `KeychainItem`, `Device`, `BackgroundTransfer`).
+*   `/src/App.tsx`: The primary state router. Houses active navigation, sidebar frames, quick-action overlays, and global mock state stores.
+*   `/src/components/DashboardView.tsx`: Hosts list, connection triggers, and background file-transfer progress bars.
+*   `/src/components/SftpView.tsx`: Dual-pane local-to-remote secure file transmission and folder generation lists.
+*   `/src/components/TerminalView.tsx`: Interactive multi-tab mock SSH shell supporting customized terminal parser actions.
+*   `/src/components/SnippetsView.tsx`: DevOps script store with full search index, copy utility, and custom snippet registration.
+*   `/src/components/KeychainView.tsx`: Secure local keystore sandbox with passphrase disclosure controls, strength validators, and SHA256 fingerprints.
+*   `/src/components/SettingsView.tsx`: Profile configuration forms, feature toggle switches, and local storage state resets.
+*   `/src/components/BriefOverlay.tsx`: In-app system documentation and layout specifications viewer.
+
+---
+
+## 3. Core Functional & Interaction Guidelines
+
+When expanding HostKeeper features, future agents must adhere to the following implementation behaviors:
+
+1.  **Icon Guidelines:**
+    *   All icons **MUST** be imported strictly from `lucide-react`.
+    *   Do **NOT** write custom inline SVGs.
+2.  **Terminal Simulation Parser:**
+    *   Inside `TerminalView.tsx`, the interactive shell handles input commands.
+    *   Always extend the mock commands list (`help`, `ls`, `docker ps`, `uname -a`, `ping 8.8.8.8`, `cat server.js`, `keychain`, `clear`) rather than falling back to blank prompts.
+3.  **Real-time SFTP Actions:**
+    *   SFTP View simulates file transmission. Clicking a file or the upload/download button triggers path transfers with real-time UI feedback. Keep the interactive toast banners operational.
+4.  **No Unsolicited SDKs or Servers:**
+    *   Keep the app fully client-side and snappy unless requested otherwise.
+    *   Avoid creating unnecessary external backends or adding database service modules unless explicitly specified.
+
+---
+
+## 4. Development Verification Steps
+
+Before finishing any task, run these commands sequentially to guarantee app integrity:
+
+1.  **Check Linter Rules:**
+    `npm run lint` or call the `lint_applet` tool to identify imports or compilation issues early.
+2.  **Verify Production Build Compilation:**
+    `npm run build` or call the `compile_applet` tool to ensure TypeScript checks and asset optimization pass without errors.

+
+### Post-MVP Fixes
+✅ TUI layout overhaul: centered border boxes, per-row centering, context-specific footers
+✅ Status bar removed; keybindings moved inside each tab's border box footer
+✅ SFTP browser: full-width panes, SFTP-specific keybindings
+✅ Host list footer: added `Ctrl+E:edit`
+✅ UUID + timestamps auto-generated in TUI form `submit()` methods
+✅ UUID + timestamps auto-generated in storage layer (`SaveHost`, `SaveKeyPair`, `SaveSnippet`)
+✅ Git history cleaned of committed binary; `.gitignore` fixed
+✅ **host_form_tab.go**: Space/Left/Right passthrough to text input (fixes typing spaces + cursor nav)
+✅ **tui.go**: Key + snippet list refresh on save/delete
+✅ **tabs.go**: WindowSizeMsg forwarded to all tabs on resize
+✅ **sftp_browser_tab.go footer**: Added `Enter/→:open`, `←/Backspace:up`
+✅ **Form tab footers**: Added `Shift+Tab:prev`, `↑↓:nav`
+
+### Done: Responsive Layout Overhaul
+✅ **NEW `responsive.go`**: Shared helpers for adaptive layout (`wrapFooter`, `adaptiveSidePad`, `clampWidth`, `truncateStr`)
+✅ Footer auto-wraps to multi-line (full labels preserved) — no more overflow on narrow terminals
+✅ Box width clamped to terminal width across all tabs
+✅ Host/key/snippet rows truncated with `…` for long names; compact format on narrow screens
+✅ SFTP panes stack vertically when terminal < 50 cols
+✅ Tab bar truncates names on overflow
+✅ Form contentW minimum lowered from 50 to 30 for mobile (Termux)
+✅ Fixed bug: key_list_tab.go & snippet_list_tab.go dropped last row (`rows[:len(rows)-1]` excluded real data)
+✅ Breakpoints: compact (<60 cols / mobile), medium (60–100 / tablet), wide (≥100 / desktop)
+
+### Done: SFTP Stacked Mode Fix
+✅ **File**: `pkg/tui/sftp_browser_tab.go`
+✅ Stacked mode (<50 cols): render cuma ACTIVE pane (bukan 2 pane)
+✅ Pane indicator bar: `[Local]  Remote` — active disorot hijau (StatusBarStyle)
+✅ Side-by-side mode (>=50 cols): tidak diubah, tetap 2 pane
+✅ Default active pane: Local (bukan Remote)
+✅ Border height fix: `renderPane` sekarang terima `maxH` parameter, `paneStyle.Height(maxH)` → border selalu konsisten tingginya, tidak naik-turun sesuai scroll
+✅ Stacked mode: `maxH = t.height - 6` (title + indicator + border + footer)
+✅ Side-by-side mode: `maxH = t.height - 5` (title + border + footer)
