Transcripts older than 30 days are deleted by default, and nothing tells you it is happening.

One SQLite file holds every conversation. Corruption, an upgrade, or a cleanup takes all of it at once.

History is keyed to the workspace path. Rename or move the project and the chat panel comes up empty.

Nothing prunes ~/.codex/sessions, so it grows until a person deletes it — usually all of it, usually in a hurry.

general.sessionRetention deletes sessions after 30 days, and cleanup is enabled by default.

One database holds every session, it grows without limit, and nothing else has a copy.

The history file lives in the repo and is normally gitignored, so nothing backs it up and no clone has it.

Cascade conversations are protobuf: the file is on your disk and the ability to read it is not.
