Addresses the review's two registration-text accuracy findings: - The cross-thread t.join() deadlock is a process-isolation-backend property (the pump runs on the child's main event loop), so it is split out of the wide-binding REPLY bullet into its own Known Limitations entry with the correct attribution (fix belongs in this backend, not packages/core/session); the zh half-width space is removed. - The settlement note's _done_with_value def-time default-arg sentence is qualified: it guards a rebind of _check_done_value/_encode_json_plain, while a transitive encoder dep (_dump_scalar/io) rebind can still downgrade, which is registered as an accepted residual in the package README. Pairing re-recorded; corpus-wide verify-translation-pairing passes 1004.

code-runtime/ — code-execution capability family
English | 中文
Summary
The code-runtime/ group provides program execution: a model writes one program that calls host-provided functions as ordinary async calls, and a runtime executes it in isolation and returns only what the program printed and returned. One package defines the shared capability (ctx.codeRuntime), a second executes TypeScript programs in a fresh Node worker thread, and a third owns the wire protocol between a Node host and a CPython subprocess for the Python backend. Every run is independent — no state carries from one program to the next — and failures come back as part of the result, so the caller can see why a program failed and feed that back to the model.

Packages
These three packages together provide program execution; each README describes what its part does.
| Package | Role | ctx key |
|---|---|---|
code-runtime/ |
Defines what a code runtime does: run one program against host-provided bindings and report what it printed and returned | ctx.codeRuntime |
code-runtime-worker-thread/ |
Executes TypeScript programs, each in a fresh Node worker thread | registers ctx.codeRuntime |
code-runtime-python/ |
Owns the fd-3 wire protocol between a Node host and a CPython subprocess, the Python backend's protocol layer | — |
