What issue are you seeing?

I had a Codex CLI/TUI session open on my machine. I opened the same session
from my phone. The phone session appended user messages and agent work to the
same thread. The CLI/TUI remained open the whole time, but did not receive or
integrate those remote events into its live context. When I continued typing
in the CLI/TUI, it appended a second continuation from stale in-memory context
to the same JSONL transcript.

What steps can reproduce the bug?

Uploaded thread: 019e199a-3d58-7863-b06e-c84a99bd9a87

What is the expected behavior?

Expected:
If a remote client attaches to an existing live CLI/TUI session, remote events
should either:

• stream back into the CLI/TUI and update its live context, or
• be rejected/locked/forked explicitly so two clients cannot append divergent

continuations to one linear transcript.

Actual:
Both paths were appended to the same transcript file linearly, but the CLI-
side model context did not include the phone-side segment.
