Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No malicious attack was identified. The launchd relaunch behavior is part of the remote hub's sandbox handling and runs when the hub is started in that condition. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-07T20:08:49.749Z - **Finished:** 2026-10-07T20:09:47.520Z - **Download time:** 250 ms - **Static scan time:** 1994 ms - **AI review time:** 55526 ms - **Total time:** 57771 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No malicious attack was identified. The launchd relaunch behavior is part of the remote hub's sandbox handling and runs when the hub is started in that condition. - **Trigger:** Starting the hub inside the package's macOS Seatbelt sandbox. - **Impact:** This permits the package's remote hub to continue operating outside the sandbox; inspected source does not establish covert persistence or an unrelated control-surface mutation. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:09:47.520Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hub creates a temporary LaunchAgent plist and asks launchd to bootstrap the hub outside the sandbox. - **Rationale:** The install hook only makes a token-authenticated request to the local hub's upgrade endpoint, while the launchd behavior supports the package's remote hub when sandboxed. The inspected source did not establish malicious activity. - **Files touched:** package.json, dist/remote/hub-sandbox.js, dist/backend/resolve.js, dist/runtime.js, dist/remote/hub-server.js ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** package.json limits postinstall to a local upgrade notification; it does not install a nested release., hub-sandbox.js writes a temporary launchd plist and bootstraps the hub when this runtime feature is invoked., backend/resolve.js resolves the ZCode CLI executable for the app-server subprocess., runtime.js selects Bun or Node for the package's own long-lived processes., hub-server.js authenticates requests with a timing-safe token comparison. ## Affected versions and remediation This report applies to zcode-acp-server@0.48.1. - Review the evidence and your use of zcode-acp-server@0.48.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
