v0.6.0

Added

• SSH transport — serve any ExRatatui.App to remote clients over OTP :ssh. New transport: :ssh option on ExRatatui.App and a standalone ExRatatui.SSH.Daemon for direct supervision-tree use. Each connected client gets its own isolated TUI session; works as a primary daemon or as a nerves_ssh subsystem via ExRatatui.SSH.subsystem/1
• ExRatatui.Session — in-memory transport-agnostic terminal session (Rust SharedWriter + Viewport::Fixed) with new/2, draw/2, take_output/1, feed_input/2, resize/3, size/1, and close/1
• ExRatatui.SSH — :ssh_server_channel implementation that drives a Session per channel, parses ANSI input via vte, and handles PTY negotiation, window_change, and alt-screen lifecycle
• ExRatatui.SSH.Daemon — GenServer wrapping :ssh.daemon/2 with port/1 and daemon_ref/1 introspection helpers
• ExRatatui.SSH.Daemon :auto_host_key option — when set, the daemon resolves the OTP application that owns :mod, ensures <priv_dir>/ssh/ exists, and generates a 2048-bit RSA host key on first boot. Subsequent boots reuse the same key. Lets Phoenix admin TUIs and similar drop the daemon straight into a supervision tree without hand-rolling host-key bootstrap
• ExRatatui.SSH.Daemon :system_dir accepts binary paths in addition to charlists; the daemon converts them before forwarding to :ssh.daemon/2
• VTE-based input parser covering arrows, function keys, SS3, CSI modifiers, Alt+letter, Ctrl+letter, and partial-sequence buffering across feeds (SSH delivers byte-at-a-time during interactive use)
• 7 new session NIFs on ExRatatui.Native: session_new/2, session_close/1, session_draw/2, session_take_output/1, session_feed_input/2, session_resize/3, session_size/1
• Guide: guides/ssh_transport.md — architecture, quick start, nerves_ssh integration, options reference, host-key generation, troubleshooting
• Examples ship an SSH mode: examples/system_monitor.exs --ssh and examples/task_manager via TASK_MANAGER_SSH=1 (multiple clients share one SQLite database)
• README "Running Over SSH" section
• CI enforces 100% Elixir test coverage threshold (NIF modules excluded)
• Missing doctests for ExRatatui, Event, Event.Key, Event.Mouse, Event.Resize, and SlashCommands
• Callback documentation for all ExRatatui.App callbacks

Changed

• ExRatatui.Server learns a transport: :local | :ssh option and an alternate init/1 path that drives an injected Session + writer function instead of the local terminal
• ExRatatui.App gains a :transport option that dispatches between ExRatatui.Server start_link/1 and ExRatatui.SSH.Daemon.start_link/1

Docs

• Expanded moduledoc prose for ExRatatui, Event, and event struct modules
• Added coverage requirement note to CONTRIBUTING.md

Tests

• Bumped Elixir test coverage to 100% — added server, rendering, layout, event, and widget tests
• End-to-end SSH integration test exercising :ssh.daemon/2 + :ssh.connect/3 round trip with a generated host key (mount → render bytes → keystroke roundtrip → window_change)
