When a host closes a lifecycle hook’s stdout pipe, Node reports
EPIPEthrough an asynchronous stream error. The existingtry/catchguards cannot catch it, so activation and mode tracking exit with an unhandled error instead of completing quietly.Handle
EPIPEonce in the shared runtime and keep all other output errors visible. A subprocess regression closes a real output pipe for both hooks, checks ordinary output, and confirms that a non-EPIPEerror still fails.Validation: rule-copy and version checks passed;
npm testpassed (97 root, 23 Pi, 3 MCP tests). The closed-pipe regression fails on unchanged main with exit 1 andwrite EPIPE. Verified with Node 22.19.0 on macOS; Windows was not run locally.
