Bayesian SSH v1.4.1

[1.4.1] - 2026-03-05

Added

• TUI tab-based navigation: Three tabs — Connections (1), History (2), Config (3) — switchable with number keys or Tab/Shift+Tab
• Add new connection form: Press a in the Connections tab to create a connection directly from the TUI with a 9-field overlay (Name, Host, User, Port, Bastion, Bastion User, Key Path, Kerberos, Tags) and validation
• Session history view: History tab with sortable columns (Date, Name, Duration, Status), connection name filter (/), failed-only toggle (f), and reconnect on Enter
• Environment management: Config tab listing all environments with the active one highlighted; switch (Enter), create (a), or delete (d) environments without leaving the TUI
• Connection grouping by tag: Toggle grouped view with f — connections are organized under collapsible tag headers
• Quick-connect bar: Press : and type [user@]host[:port] to connect to an ad-hoc host without saving it
• Multi-select and batch operations: Space to toggle selection, Ctrl+A to select all, x to batch-delete selected connections with a confirmation dialog
• SSH command preview: Press p to see the full SSH command that would be executed, broken down by component (host, port, user, bastion, kerberos flags, key path)
• Async TCP ping with status indicators: Press P to ping the selected connection in the background; results appear as colored indicators — green ● with round-trip time for reachable, red ● for unreachable, yellow ◌ while checking
• Shared ping service (services/ping.rs): Lightweight TCP-level reachability check using tokio::net::TcpStream with timeout — no external process spawning; pings bastion host on port 22 for bastion connections

Changed

• TUI modular architecture: Split monolithic tui/app.rs (721 lines) and tui/ui.rs (572 lines) into focused modules:
  • models.rs — enums and small types (Tab, AppMode, EditState, PingStatus, etc.)
  • state.rs — App struct and state management with tokio::sync::mpsc ping channel
  • input.rs — keyboard handlers dispatched per tab and mode
  • event_loop.rs — terminal setup/teardown and main loop with async ping result draining
  • ui/mod.rs — draw dispatcher routing to tab views and overlays
  • ui/header.rs, ui/list.rs, ui/detail.rs, ui/status.rs, ui/overlays.rs, ui/history.rs, ui/config.rs, ui/helpers.rs
• Edit overlay extended: Now supports 9 fields (added Key Path); EditState includes is_new flag and validate() for required-field checks
• Ping indicators use distinct colors: Reachable (green), unreachable (red), checking (yellow) — previously all rendered identically

Fixed

• Unreachable key binding patterns: Ctrl+A select-all now correctly takes precedence over plain a add-connection; removed dead g grouping arm that was shadowed by go-to-top
