Linux; repo Playwright 1.60.0; /usr/bin/google-chrome; real OpenSSH server on port 2222.

main web 8693 / server 16733:
SSH command exited 255: Host key verification failed.
Settings > Devices > Add source > Machine over SSH > Test connection:
Device probe host failed: Could not communicate with device support. Try refreshing devices.
Saved-host status: Could not connect to this host over SSH.

PR web 5733 / server 13773:
Same target, port and identity, still untrusted:
Test connection and saved-host status explain that the key is not trusted on the machine running this T3 Code server and instruct connecting once with ssh there.
Changed the real sshd host key: changed-key guidance, including ssh-keygen -R.
Unresolvable ssh-probe.invalid: Could not resolve the host name ... Name or service not known.
Closed port 2223: Could not reach ... Connection refused; check host, SSH server, address and port.
Untrusted login key: SSH login failed while connecting ... Permission denied (publickey); login must work without a prompt.
Accepted the server key with OpenSSH and used the authorized key: Connection checks passed / Connected / Android available.
Retry saved host: SSH failure cleared; Android list may be incomplete because emulator is not installed.
Port 22 on local address: Already available locally.

Added /home/user/main as a project through the app; started real Codex gpt-6.1-sol turn through composer.
Actual command: git rev-parse --is-inside-work-tree && pwd
Result: true; /home/user/main; assistant returned SSH_PROVIDER_PATH_OK.

2 files passed; 81 tests passed.
GitHub head checks passed; no source edits, commits or pushes.

Not exercised: native mobile/Electron, macOS/Windows hosts, ProxyJump/bastion, actual emulator/device launch, external remote/tunnel clients.
Setup incident: first root-clone startup selected ~/.t3 and applied migrations before it was stopped. All PR verification used explicit task-only home .t3-pr31695.
