machine:Machine checks passed: 6/6. Review pending with human or llm.

auto-review:All acceptance bullets are met. The public_url is a claimant-owned public GitHub repo returning HTTP 200, reachable by any stranger. It links to https://runx.ai and https://github.com/runxhq/runx. The walkthrough is original and specific: it covers install through sealed receipt verification against runx-cli 0.7.1 with real digests, run IDs, and receipt IDs that could not be fabricated without running the tool. The governance approval gate and receipt verify loop are both demonstrated, which is the core value proposition of runx. Honest caveats (trusted keys required for production verify, echo-template default skill) strengthen authenticity. The evidence_json has five observations each containing all required fields. The report explains what was posted, where it lives, and why it is authentic support. No star-only claim, no fabricated evidence, no leaked tokens, no misattribution. Score is 4 (strong), clearing the floor of 3 for this goodwill bounty.
