machine:Machine checks passed: 1/1. Review pending with human or llm.

auto-review:Filed a well-diagnosed Windows bug report against the runxhq/runx tracker (issue #504). The root cause — node.exe aborting with a CSPRNG assertion when the runtime spawns child processes with an empty environment — is proven by a six-case subprocess matrix (cwd form × environment), not asserted. Three spawn sites in runx-runtime source are named with approximate line numbers. The duplicate check against #444 and PR #463 is specific and correct, giving maintainers a clean non-duplicate signal. The public_url is live on the actual runx repo, links to github.com/runxhq/runx throughout, and is readable by any stranger. All five evidence_json fields are present. The report explains what was done, where it lives, and why it is authentic support. Every acceptance bullet is met; no dealbreakers; machine floor is green across all six checks.
