Package altscreen reconstructs the current visible state of a full-screen TUI (Claude Code, vim, htop, less, fzf…) from a window of raw pty output, and serializes it back into a self-contained repaint sequence.

Package build holds version metadata stamped into the binary at link time.

Package cert manages the daemon's self-signed TLS certificate.

Package completions is the single source of truth for the subcommand and flag inventory of `mtroamd` and `mtroam`, used by the cmd/gen-completions generator to emit bash/zsh/fish completion scripts.

Package daemon orchestrates the long-running pieces of mtroamd: the session registry, the QUIC listener, and the unix-socket IPC server that `mtroamd connect` talks to.

Package ipc is the unix-socket IPC between `mtroamd serve` (the long-running daemon that owns the session registry) and `mtroamd connect` (the SSH-side helper that runs once per bootstrap to allocate or reattach a session).

Package protocol implements the wire format for meshTerm's mtRoam protocol over QUIC.

Package pty wraps creack/pty to spawn a child process attached to a PTY pair, exposing the io.Reader / io.Writer / io.Closer + SetSize surface that internal/session expects.

Package ptyclient is the daemon-side client for an out-of-process PTY sidecar.

Package ptysidecar implements the per-session PTY-owning helper process.

Package release implements mtroamd's self-update path: fetching signed binaries from GitHub Releases, verifying their integrity, and atomically swapping the running binary in place.

Package secret implements mtroamd's in-memory secret broker with value-hiding delivery.

Package session owns the per-session state for mtroamd: the output ring buffer, the Session value, and the concurrent registry.

Package svcmgr abstracts the host service manager (systemd-user / launchd / direct exec) so mtroamd's uninstall + update flows don't need to branch in three places.

Package transport binds the QUIC listener to the daemon's session registry.
