Sessions & artifacts

A session is the durable record behind an answer: messages, tool calls, results, approvals, usage, artifacts, checkpoints, attachments, and lineage.

Storage

Session transcripts and artifacts live under ~/.jeden/sessions/. Oversized tool results are persisted as artifacts and replaced in the model loop with compact references.

Inspect and recover

$ jeden sessions 20
$ jeden show <session>
$ jeden export <session> output.json
$ jeden artifacts <session>
$ jeden artifact <session> <name> output.bin
$ jeden resume <session> "continue"

Resuming starts a fresh session seeded with selected history; it does not append destructively to the original record.

Interactive lineage

Checkpoints and rewind

/checkpoint before-refactor
/checkpoint list
/rewind <checkpoint-event-id>

A checkpoint records the exact model-visible context. Rewind appends a new active lineage without deleting the abandoned history.

Attachments

/attach path/to/context.txt
/attachments
/detach <id|all>

The attachment tray accepts bounded workspace-jailed text and PNG, JPEG, GIF, or WebP inputs for the next submitted turn.
