fix(remote): restore auto-connect SSH hosts on Desktop start - #800
A discovered SSH connection with auto-connect already enabled stayed disconnected after Codex Desktop was fully quit and relaunched through codexhost. The remote workspace came back only after a manual disconnect and connect in Settings.
Turning auto-connect on again does not reopen a host that already has the flag set, and the previous restore ran only when Web listed hosts, once, even if the host was still disconnected. A codexhost/* method refusal on that connection was also remembered for the life of the request client, so a refusal from before the remote control channel was ready was not tried again.
On Desktop start, and when Web reads the host list, codexhost now turns auto-connect off and back on for SSH hosts that are disconnected or failed, then checks again a few times (at most 5 attempts per host in one Desktop lifetime). Hosts that are already connecting, and hosts the user turned off, are left alone. A state read that fails does not change the flag. After the host is connected, remembered method refusals on that connection are dropped so the remote control channel can answer. Remote Control still receives a single enable when its catalog is read.
NODE_OPTIONS=--max-old-space-size=8192 npx tsc -p tests/tsconfig.json --noEmit --pretty false — passed. The same command at the default heap aborted with out-of-memory; the 8GB rerun passed.
npx vitest run --config tests/vitest.config.js packages/renderer-extension/test/renderer-binding-probe-host-catalog.test.ts — 26 passed.
npx eslint on the changed TypeScript files — passed.
Node evaluation of the built Desktop controller expression: a disconnected autoConnect SSH host is switched off, then on.
Pre-commit prettier --check on the staged files — passed.
Not run:
Live Codex Desktop, a real SSH host, and a real Harness. This environment has none of them. The startup path and the sticky method-refusal cache were confirmed in code and covered by the tests above. Remaining risk: a native connection state other than disconnected, error, connecting, or connected is not toggled, and the retry window is about a minute after launch.
Full npm run check, full Vitest, full npm run lint, and Playwright e2e. Dependency direction is unchanged. macOS and Windows were not run; the change is TypeScript in the renderer and desktop-control.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

The new SSH auto-connect recovery can leave a host disconnected, or even turn off a user's auto-connect setting, if a catalog read fails right after the temporary disable. A Harness method refusal can also stay cached after recovery. These paths need specific failure timing, but they should be fixed before merge.

Web 恢复连接后也要清除方法拒绝缓存。
如果 Web 在启动定时检查结束后恢复 SSH 连接，rendererRemoteSession 会丢弃 restore 返回的已连接主机。若连接复用原模型客户端，方法拒绝缓存可能保留，导致后续请求仍被拒绝。
Web 路径观察到连接恢复时，应通知渲染器清除对应缓存并刷新 Harness 可用性。连接在本轮状态读取后才恢复时，也应在后续读取中处理。

Keep SSH auto-connect when the probe lacks restoreSshConnection.
The remote-control: condition at packages/desktop-control/src/renderer-remote-sessions.ts:88-92 now gates the auto-connect branch. SSH host IDs fail this test. When api.restoreSshConnection is absent, the SSH hook at lines 82-87 is skipped. Enabled, disconnected SSH hosts then remain disconnected.
Restore SSH auto-connect through the existing probe when it has no hook. Alternatively, ensure that the Controller replaces any probe that lacks the new hook. The current install path does not do that.
Schedule retry after an acknowledged enable that later fails.
After connect(hostId, true) succeeds, restore reads the state once (lines 73-78). If that state is not connected and not a disconnected or error with an error, retryAt stays Infinity (line 29). Later restore calls then check only for connected (lines 18-27). They do not turn a later error into a retry.
If native setAutoConnect can resolve while the host is still connecting, or while it is disconnected without an error, this host can stay disconnected until the user acts or the connection succeeds. The enable has already been acknowledged, so the outcome is known. Line 80 already treats it as a failure (failed = acknowledged). The code does not carry that failure into a retry.
Record the acknowledged enable on the attempt. In the observation path at lines 18-27, schedule retryAt from the existing backoff when the state is disconnected or error with an error. Keep the rule that writes with unknown outcomes are not resent automatically.
