Editing earlier code invalidates its namespace session when you next evaluate. Run page starts fresh. Documents can require other documents. Hidden panels remain in the namespace; Show restores them.

Prompt context

Targets may be edited. References are read-only. Excluded panels are not sent. Hiding a panel does not change its context role.

Pinned instructions

Referenced definitions

Static lookup across journal namespaces. Codex can also search supported library APIs and read their docs and examples itself, without accessing other user documents or evaluating code. Imports are edited in the document's ns header.
