## Summary Lower the `js_repl` minimum Node version from `24.13.1` to `22.22.0`. This updates the enforced minimum in `codex-rs/node-version.txt` and the corresponding user-facing `/experimental` description for the JavaScript REPL feature. ## Rationale The previous `24.13.1` floor was stricter than necessary for `js_repl`. I validated the REPL kernel behavior under Node `22.22.0` still works. ## Why `22.22.0` `22.22.0` is a current, widely packaged Node 22 release across common developer environments and distros, including Homebrew `node@22`, Fedora `nodejs22`, Arch `nodejs-lts-jod`, and Debian testing. That makes it a better exact floor than guessing at an older `22.x` patch we have not validated. `22.x` is also a maintenance branch that will be supported through April 2027, where the previous maintenance branch of `20.x` is only supported through April of this year. ## Changes - Update `codex-rs/node-version.txt` from `24.13.1` to `22.22.0` - Update the `/experimental` JavaScript REPL description to say `Requires Node >= v22.22.0 installed.`
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.
Network access and filesystem read/write roots are controlled by
SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.
Seatbelt also supports macOS permission-profile extensions layered on top of
SandboxPolicy:
- no extension profile provided:
keeps legacy default preferences read access (
user-preference-read). - extension profile provided with no
macos_preferencesgrant: does not add preferences access clauses. macos_preferences = "readonly": enables cfprefs read clauses anduser-preference-read.macos_preferences = "readwrite": includes readonly clauses plususer-preference-writeand cfprefs shm write clauses.macos_automation = true: enables broad Apple Events send permissions.macos_automation = ["com.apple.Notes", ...]: enables Apple Events send only to listed bundle IDs.macos_accessibility = true: enablescom.apple.axservermach lookup.macos_calendar = true: enablescom.apple.CalendarAgentmach lookup.
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.
