UART0 and admin SSH submit to one bounded queue, and one dispatcher task is the sole caller of `esp_console_run()`. Consequently, SSH commands execute the canonical UART0 handlers and produce the same status and mutation behavior rather than using a second command implementation. Remote output is routed into the authenticated session's bounded output ring; only the SSH transport task accesses wolfSSH.
Admin SSH supports four-entry per-session command history with Up/Down, shared whole-line Tab completion using the same hints as UART0, inline cursor editing with Left/Right, Home/End (including Pos1/Ende terminal sequences), Backspace/Delete, Ctrl-C, and visible or no-echo interactive prompts. History is RAM-only, private to the session, and wiped on disconnect. Ping callbacks enqueue bounded typed results so all formatting remains on the dispatcher task.
Admin SSH supports four-entry per-session command history with Up/Down, shared whole-line Tab completion using the same hints as UART0, inline cursor editing with Left/Right, Home/End (including Pos1/Ende terminal sequences), Backspace/Delete, Ctrl-C, and visible or no-echo interactive prompts. A Tab that cannot extend an ambiguous command prefix prints the same matching candidates supplied to the UART0 completion callback, then redraws the current input line. History is RAM-only, private to the session, and wiped on disconnect. Ping callbacks enqueue bounded typed results so all formatting remains on the dispatcher task.
`reboot`, `ssh stop`, session disconnect, and SSH host-key reset/rotation are deferred until the command acknowledgement has left both the administration output ring and transport TX buffer. The shell stops accepting another command while such an action is pending. SSH host-key replacement or service stop closes all SSH sessions; reconnect and verify the new fingerprint where applicable. Web recovery credentials/certificates, Wi-Fi secrets, and interactive user passwords/keys are available to authenticated administrators and must therefore be treated as remotely accessible administrative material. `user bootstrap` and `user recover --force` remain UART0-only. A connected administrator also cannot generate its own replacement password remotely, preventing the one-time password from being lost during self-revocation. SSH does not provide `exec`, SFTP, SCP, forwarding, or subsystems.
