ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a narrowly scoped SSH lifecycle fix: desktop shutdown now leaves remote work running while explicit disconnect still stops managed servers. The production logic is isolated and accompanied by focused process-ownership tests; the other changes are documentation or test-only. You can add or adjust custom eligibility rules. Learn more. |

Tunnel cleanup no longer stops the remote server. Explicit disconnect still stops it. Tests cover managed and external servers, and documentation records the behavior. ChangesRemote server lifecycle
Priority: ⬆️ High Estimated code review effort: 3 (Moderate) | ~20 minutes Severity of issue fixed: High Merge Risk: ⚪ Minimal · up to Managed SSH servers now remain available across desktop-client closure and reconnects while explicit disconnect continues to stop them. The test fixture preserves its parent environment, so no current merge-blocking risk remains. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

What Changed
Closing the desktop client stopped its managed SSH server and interrupted running agent turns. Tunnel teardown now closes only the local forward; explicit Disconnect/Remove still stops a managed server.
Reconnect also preserves managed ownership when the default runtime file identifies the same PID. Without this check, the launcher mistakes its own surviving server for an external one and sends it SIGTERM.
Why
Fixes #10934. Remote work should survive a client restart. This keeps #9843's correct process ownership and the existing explicit-stop behavior, including stop errors and external-server protection.
Validation: reproduced three failing assertions on unmodified main, then passed all 37 focused tunnel and runner-process tests. The reconnect regression runs the generated shell script against an isolated HTTP process and verifies no SIGTERM, the same live PID, and preserved ownership. SSH package typecheck, targeted lint, and formatting pass. No live SSH host, desktop/Codex session, or personal T3 state was used.
