## Summary This changes `js_repl` so saved references to `codex.tool(...)` and `codex.emitImage(...)` keep working across cells. Previously, those helpers were recreated per exec and captured that exec's `message.id`. If a persisted object or saved closure reused an old helper in a later cell, the nested tool/image call could fail with `js_repl exec context not found`. This patch: - keeps stable `codex.tool` and `codex.emitImage` helper identities in the kernel - resolves the current exec dynamically at call time using `AsyncLocalStorage` - adds regression coverage for persisted helper references across cells - updates the js_repl docs and project-doc instructions to describe the new behavior and its limits ## Why We already support persistent top-level bindings across `js_repl` cells, so persisted objects should be able to reuse `codex` helpers in later active cells. The bug was that helper identity was exec-scoped, not kernel-scoped. Using `AsyncLocalStorage` fixes the cross-cell reuse case without falling back to a single global active exec that could accidentally attribute stale background callbacks to the wrong cell.
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_launch_services = true: enables LaunchServices lookups and open/launch operations.macos_accessibility = true: enablescom.apple.axservermach lookup.macos_calendar = true: enablescom.apple.CalendarAgentmach lookup.macos_contacts = "read_only": enables Address Book read access and Contacts read services.macos_contacts = "read_write": includes the readonly Contacts clauses plus Address Book writes and keychain/temp helpers required for writes.
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.
