Codex desktop app default thread list does not include remote-ssh-codex-managed host after restart

Start at the app-server list_threads entry point and compare default list_threads(limit=50) with the query and hostId behavior described in the issue. Use the remote session_index.jsonl, state_5.sqlite, and app-server.log evidence to reproduce the omission; done means recent threads from remote-ssh-codex-managed hosts appear in the default list, merged and sorted by recency, with regression coverage.

Codex desktop app default thread list does not include remote-ssh-codex-managed host after restart

What steps can reproduce the bug?

Environment

• Codex CLI version: 0.142.3
• Codex App / Desktop remote SSH workflow
• Remote host: remote-ssh-codex-managed:codexu
• Remote cwd: /home/codexu/workdir
• Remote user: codexu
• Shell: bash
• Date observed: 2026-07-21
• Config: disable_response_storage = false

Issue

After restarting Codex, history for the current remote directory appears missing in the default thread/history list.

The records are not actually deleted. They exist locally on the remote host and can be found by search, but the default list_threads / recent history list does not include the remote-ssh-codex-managed:codexu host.

Evidence

On the remote host:

• /home/codexu/.codex/sessions contains historical rollout files.
• /home/codexu/.codex/session_index.jsonl contains the expected thread IDs.
• /home/codexu/.codex/state_5.sqlite has 7 threads for /home/codexu/workdir.
• Threads are not archived and have non-empty previews.

Codex App behavior:

• list_projects includes project /home/codexu/workdir with hostId remote-ssh-codex-managed:codexu.
• read_thread works when passing hostId=remote-ssh-codex-managed:codexu.
• list_threads(query="workdir") returns the missing remote threads.
• But default list_threads(limit=50) only returns local and remote-ssh-discovered:codex_50, not remote-ssh-codex-managed:codexu.

Expected behavior

Default recent thread list should include threads from all available hosts, including remote-ssh-codex-managed:*, merged and sorted by recency.

Actual behavior

Default recent thread list silently omits the remote-ssh-codex-managed:codexu host, making it look like history was lost after restart.

Additional suspicious log

/home/codexu/.codex/app-server-control/app-server.log contains:

Error: app-server control socket is already in use at /home/codexu/.codex/app-server-control/app-server-control.sock
