## Description This PR makes new threads with `history_mode = "paginated"` persist `ItemCompleted(item: <turn_item>)` in their rollout JSONL file. Legacy threads keep persisting the existing legacy events. Because the format is selected per thread, a rollout is either legacy or paginated; we do not need to support mixed rollouts containing both representations. This PR depends on [#31473](https://github.com/openai/codex/pull/31473). ## Why Paginated thread history needs stable turn/item IDs and completed item snapshots so the later SQLite projector can materialize appended rollout JSONL without rebuilding the whole thread. Keeping the legacy persistence policy unchanged avoids changing historical rollouts or the readers that still consume them. ## What changed - Made rollout filtering history-mode aware. Paginated threads keep completed canonical `ItemCompleted` events and drop their redundant legacy projections; legacy threads keep the existing event set. - Made forks inherit the source thread history mode, so copied legacy history is never filtered as paginated. - Made paginated threads assign IDs to locally-created response items even when `Feature::ItemIds` is off, and reject streamed output items that arrive without server IDs. - Updated legacy turn replay, rollout list/search, and SQLite metadata extraction to understand completed canonical user-message items.
codex-protocol
This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between codex-core and codex-tui, as well as "external types" used with codex app-server.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce Ext-style traits to add functionality to types in other crates.
