Only plain text response appears when resuming conversation; tool call history missing

0.47.0

Pro plan

What platform is your computer?

macOS

What issue are you seeing?

In the Codex CLI, when I resume a conversation that I had before, only the plain text response message is still present. All previous tool invocation interactions (like edit file, create file, or other tool calls) are missing.

What steps can reproduce the bug?

1. Start a conversation with Codex CLI and ask it to perform tool calls such as editing or creating a file.
2. End or exit the conversation.
3. Later, resume the same conversation from the CLI.
4. When the conversation resumes, only the plain text response message is shown and all tool call logs have vanished.

What is the expected behavior?

When I resume a conversation, the full conversation history should be preserved, including all previous tool call interactions (such as edit file, create file, etc.). The CLI should display all responses and tool call outputs.
