The object branch counted every own key before applying the size bound, so a forged done.value with millions of keys and a small cap forced an O(frame) walk — contradicting the O(cap) guarantee the comment promised and able to block the host event loop. Bail mid-count the instant the running minimum encoding (braces + 4 bytes/entry + commas) crosses maxBytes, and drop the now -redundant post-count check the loop subsumes. Add a Proxy-based test proving a 2M-key object enumerates fewer than 1000 keys under a 64-byte cap. Also correct the checkDoneValue JSDoc: per-scalar byte length is measured via scalarJson (exact BigInt digits for beyond-safe integers), not JSON.stringify.
code-runtime/ — code-execution capability family
English | 中文
The code-execution capability seam (see capability seams): an abstract runtime interface for executing one model-written program against host-provided async bindings, capturing what it printed and returned. The consumer is the tool registry's Code Mode (tools: { mode: code } — the run_code tool and the SDK generated in the loaded runtime's language); design in the Code Mode Agent Note. Product packages.
| Package | Role | ctx key |
|---|---|---|
code-runtime/ |
Code-execution seam and shared vocabulary | ctx.codeRuntime |
code-runtime-worker/ |
Worker-thread backend | registers ctx.codeRuntime |
Backends register the seam without changing its consumer. The child READMEs own language, isolation, and execution-budget details.
