The rebindable-BaseException vector the bot flagged existed in every except clause of the settlement path, not just the _run outer catch: safe_model_traceback (three guards) and the post-done flush swallow resolved the module-global BaseException at runtime, so a __main__.BaseException rebind plus a throwing __str__ could let a render-time exception escape and lose the done frame. Bind BaseException into a _run local (at the top) and a closure cell in _make_failure_reporter, and change every such except clause to catch the local — immune to a one-line rebind.

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.

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 | — |
