Module codex 

Typed schema for Codex rollout JSONL (~/.codex/sessions/.../rollout-*.jsonl).

Each line is an envelope {timestamp, type, payload}. The type selects the envelope kind; for response_item the inner payload.type selects the conversation item. Discriminants we don’t model land in Unknown variants so the audit can enumerate them; unmodeled fields land in extra maps.

Structs

CodexLine

One line of a Codex rollout file.

EventMsg

A UI event echo. We only need its discriminant for the audit.

SessionMeta

Codex session_meta payload.

TurnContext

Codex turn_context payload (loosely modeled — many policy fields).

Enums

CodexRecord

A Codex envelope.

ResponseItem

A canonical conversation item (response_item payload).
