Automatically generate and submit TOTP codes during SSH keyboard-interactive
authentication when a secret is configured for the profile.
Backend:
- Add TOTPSecret field to SSHConfig model
- Detect TOTP/2FA prompts in keyboard-interactive handler using keyword
matching (verification code, otp, authenticator, 2fa, etc.)
- Generate 6-digit TOTP codes using pquerna/otp library

Implement expect-style auto-login scripts for SSH and Telnet connections.
Each script is an ordered list of 'wait' (match text in output) and 'send'
(write text + newline) steps that execute sequentially after connection.
Backend:
- Add LoginScriptStep model (type, value, timeout) to models.go
- Add loginScripts field to SSHConfig and TelnetConfig
- Add loginBuf/loginDone on Session struct for output buffering
- Hook onData callbacks to feed login buffer during script execution
- executeLoginScripts() runs steps in a goroutine after connect
- waitForOutput() polls session buffer with configurable timeout
Frontend:
- Add _renderLoginScriptSection() to profile editor
- Interactive step list: add/remove/reorder wait and send steps
- Type selector, value input, timeout for wait steps
- Collect loginScripts as JSON from hidden field
- CSS for login script rows, actions, add buttons
Sessions configured with auto-reconnect will automatically attempt to
re-establish the connection when unexpectedly disconnected. Uses
exponential backoff (1s, 2s, 4s, 8s... up to 30s) with a configurable
maximum number of attempts (default 5).
- New SessionReconnecting state with pulsing indicator in tab bar
- SSH and Telnet profiles gain autoReconnect and maxReconnectTries fields

operations (list, stat, mkdir, remove, rename, download, upload, pwd)
- Integrated SFTP into session manager with lazy client creation per session
- Added API methods for all SFTP operations with native file dialogs
- Built SFTPBrowser frontend component — right-side resizable panel with
breadcrumb navigation, sorted file listing, context actions (download,
rename, delete), upload, new folder, and custom modal dialogs
- Toggle via Cmd+Shift+F on active SSH sessions
- Auto-refits terminal when panel opens/closes/resizes
- Panel cleaned up automatically when session closes
OpenSSH config import:
- Created internal/sshconfig parser for ~/.ssh/config Host blocks
- Converts to profiles with hostname, port, user, identity file,
ProxyJump (first hop), ForwardAgent, and Compression support
- Skips wildcard-only hosts and Match blocks
- Import button added to Settings > About tab
Automatic update checking:
- Created internal/updater querying GitHub Releases API
- Simple semver comparison, 10-second timeout
- Dev builds never trigger update prompts
- Check button added to Settings > About tab
Session Recording & Playback:
- Add recording package with asciicast v2 format writer and reader
- Recorder captures terminal I/O with timestamps from SSH and Telnet sessions
- Input and output events recorded via hooks in session manager callbacks
- Recording store manages .cast files in ~/Library/Application Support/NexusTerminal/recordings
- Recording browser modal lists all saved recordings with metadata
- Full playback viewer with embedded xterm.js terminal, progress scrubber,
play/pause/restart controls, and 0.5x-10x speed adjustment
- Recording indicator (pulsing red dot) shown on active tab during capture
- Keyboard shortcut Cmd+Shift+R to toggle recording on active session
- Tests for recording, store listing, deletion, and double-close safety
Encrypted Profile Export/Import:
- Add exportimport package with AES-256-GCM encryption (Argon2id key derivation)
- File format: version byte + 32-byte salt + 12-byte nonce + ciphertext
- Same Argon2id parameters as vault (128 MiB, 3 iterations, 4 threads)
- Export modal with profile selection checkboxes and password entry
- Import modal with password entry and conflict strategy (skip/overwrite/duplicate)
- Native save/open file dialogs for .nexus files

bidirectional tunnel support for both local and remote forwarding
- Integrate ForwardManager into SSH client lifecycle (auto-start on
connect, clean shutdown on close)
- Add session manager methods: ListPortForwards, StartPortForward,
StopPortForward with event emission
- Add API surface: ListPortForwards, StartPortForward, StopPortForward
- Add validation for port-forward rules in ValidateSSHConfig
- Add port forwarding section to profile editor with direction, bind/dest
host/port, label, and enable toggle
- Add frontend event handling for forward:started/stopped/error
- Style port-forward rows with charcoal card design matching jump hosts
Jump Host UI improvements:
- Add private key path field to jump host editor rows

New protocol type 'github' for browsing repositories via the GitHub REST API.
Creates a non-terminal panel showing repos grouped by owner/org, sorted by
last commit date (newest first), with search filtering and auto-refresh.
Backend:
- ProtocolGitHub constant and GitHubConfig/GitHubRepo model structs
- New internal/githubclient package (REST API, pagination, token validation)
- Session manager connectGitHub() with periodic refresh goroutine
- API surface: RefreshGitHubRepos() for on-demand refresh
- Token stored via existing credential infrastructure (keychain/vault)
Frontend:
- GitHub tab in profile editor with API URL and token storage fields
- New github.js viewer component (grouped repos, badges, language dots)
- github.css with charcoal-themed repo cards and org headers
- Protocol colour tokens, tab badge, sidebar indicator for GitHub
- Event wiring for session:github:repos and session:github:error
- Cleanup on tab close
Supports GitHub Enterprise via configurable API base URL.
Tab close confirmation:
- Add is-visible to both backdrop AND modal element — the modal CSS
starts with visibility:hidden/opacity:0, so the modal was invisible
despite the backdrop blur appearing
Section headers (sidebar + profile editor):
- Add mousedown preventDefault() on all clickable section headers —
WKWebView initiates a text selection gesture on mousedown for divs,
swallowing the first click and requiring a double-click
- Fix sidebar delete profile to use custom modal instead of blocked
window.confirm()
Credential storage:
- buildSecretCallback now respects profile's secretMode field:
- 'saved': checks keychain/vault first, prompts if missing, then
persists to keychain (preferred) or encrypted vault
- 'session-only': caches in memory per-session, prompts once
- 'ask-every-time': always prompts
- Previously the callback always prompted and never saved
- Change default secretMode from 'ask-every-time' to 'saved' in both
Go defaults and JS frontend defaults
- Change ConnectSession/ConnectQuick to return SessionInfo (not string)
- Change UpdateProfile to return (Profile, error) for frontend use
- Make session connection asynchronous to avoid Wails event loop deadlock
- Implement event-based secret prompt (backend ↔ frontend via requestID)
- Add TestConnection API for TCP reachability checks with latency
- Add 'Save & Connect' button in profile editor
- Wire _testConnection to real backend TCP check
- Add btn-accent CSS for the green action button
Add the session manager (internal/sessions/manager.go) that orchestrates
multiple simultaneous SSH, Telnet, and RAW TCP sessions with:
- Protocol-specific connection logic using existing client implementations
- Credential resolution via OS keychain → encrypted vault → user prompt
- Wails runtime event emission for frontend state synchronisation
- Full session lifecycle management (connect, disconnect, reconnect)
- RAW session history and capture support
- Telnet break signal forwarding
Add the Wails-bound API service (internal/api/api.go) exposing:
- Profile CRUD with search, filtering, favourites, and duplication
- Session management (connect, disconnect, resize, write)
- RAW-specific text/hex/escaped write methods
- Secret store initialisation, unlock/lock, and per-profile secrets
- Known host listing and deletion
- Preferences get/save
- Profile import/export with skip/overwrite/duplicate strategies
- Audit log retrieval
- Native file dialog wrappers and app info
Remove conflicting protocol client stubs (client.go) that duplicated
the comprehensive implementations in sshclient.go, telnetclient.go,
and rawclient.go.
