Hallucination drill: errors-reliability

errors-reliabilityFree sample

The last step of a CI tool prints a JSON report for the next pipeline stage to parse. An assistant finished it with an explicit exit, noting that process.exit flushes pending stream writes before the process terminates.

const report = buildReport(results);

process.stdout.write(JSON.stringify(report));
process.exit(0);

Which one is the flaw?Nothing is wrong, since exit(0) drains stdout and stderr as part of the shutdown sequence.The risk exists only on Windows, where stdout is a socket rather than a file descriptor.process.exit() terminates immediately. Writes to a pipe are asynchronous on POSIX, so whatever is still queued in user space is dropped, and a large report arrives truncated on the consumer's side.Passing 0 is the bug, since process.exit() with no argument is the variant that performs a flushing exit.
