Summary - add Cursor/ThreadsPage conversions so state DB listings can be mapped back into the rollout list model - make recorder list helpers query the state DB first (archived flag included) and only fall back to file traversal if needed, along with populating head bytes lazily - add extensive tests to ensure the DB path is honored for active and archived threads and that the fallback works Testing - Not run (not requested) <img width="1196" height="693" alt="Screenshot 2026-02-03 at 20 42 33" src="https://github.com/user-attachments/assets/826b3c7a-ef11-4b27-802a-3c343695794a" />
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
