Does forking a Codex conversation preserve full context?

Just wanted to confirm the following behavior: When Codex forks a thread, the entire previous context is used 1:1 in the new thread. If the original thread had already been compacted earlier, the fork inherits whatever the persisted rollout now contains, including any prior compaction artifacts. It does not recover pre-compaction detail, and it does not create a new compacted version just because of the fork. As a thought experiment: you could manage the thread and context yourself because all of the text is still there at the file level. It is just no longer sent to the model after automatic compaction.
