Native transport SSH client with continuous infrastructure telemetry.
Built on Erlang/OTP transport, OS credential stores, xterm.js terminal emulation, and zero telemetry. Completely functional in air-gapped environments without external accounts.

Architecture Invariants
Design decisions prioritizing security and minimal overhead
Erlang Native :ssh Engine
Eliminates reliance on external ssh binaries or OpenSSH-for-Windows. Connects directly via OTP :ssh_connection in BEAM memory.
OS Credential Stores
Secrets never touch plaintext configs. Direct integration with Windows Credential Manager and Linux Secret Service (libsecret) with memory-only passphrase caching.
Focus-Aware Polling
Background hosts dynamically throttle telemetry checks. Non-interactive exec channels are used for metrics rather than holding open idle PTY shells.
