Closing the control pipe after the result rejected outstanding birpc calls; an unawaited binding promise then crashed the child and its trace reached the result logs. Once the result is returned or the pipe closes, binding calls now never settle, including those the closure rejects.

ptc-runtime/ — PTC execution capability family
English | 中文
Summary
The ptc-runtime/ group executes model programs against host-provided async functions. The default Node backend starts a fresh process under the configured sandbox policy. Its opt-in executionMode: persistent-in-memory keeps a separate confined REPL for each explicit state owner; memory ends with the process or owner. The experimental Python backend uses a fresh CPython process. Failures return as results for callers to diagnose or present to the model.

Packages
These three packages together provide program execution; each README describes what its part does.
| Package | Role | ctx key |
|---|---|---|
ptc-runtime/ |
Defines what a PTC runtime does: run one program against host-provided bindings and report what it printed and returned | ctx.ptcRuntime |
ptc-runtime-node/ |
Executes TypeScript in fresh processes under file policy or an opt-in retained REPL under the same file policy | registers ctx.ptcRuntime |
experimental/ptc-runtime-python/ |
The experimental Python backend: owns the fd-3 wire protocol between a Node host and a CPython subprocess and the CPython runtime implementation | — |
