Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The entrypoint and lifecycle metadata show a library whose prepublishOnly script builds it. The inspected POST sends telemetry to the package-aligned API, and the scanner’s callback signal does not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-07T22:08:07.855Z - **Finished:** 2026-10-07T22:08:32.895Z - **Download time:** 515 ms - **Static scan time:** 3362 ms - **AI review time:** 21162 ms - **Total time:** 25040 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 confirmed attack surface was identified. The reported POST is SDK telemetry directed to the package’s own API host. - **Trigger:** Telemetry is sent when the SDK queues and flushes events during normal use. - **Impact:** This is consistent with the package’s SDK function; no unrelated data recipient or malicious behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T22:08:32.895Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The transport posts event batches to api.arcyai.com using its configured token. - **Rationale:** The entrypoint and lifecycle metadata show a library whose prepublishOnly script builds it. The inspected POST sends telemetry to the package-aligned API, and the scanner’s callback signal does not establish malicious behavior. - **Network endpoints:** https://api.arcyai.com/api/v1/sdk/telemetry ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes the built library entrypoints and shows prepublishOnly runs the build., The reported callback is SDK telemetry sent to api.arcyai.com, matching the package’s ARCY identity., Telemetry sends queued events with a bearer token to the SDK endpoint; no unrelated recipient or credential harvesting was identified. ## Affected versions and remediation This report applies to arcy.js@0.2.0. - Review the evidence and your use of arcy.js@0.2.0 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.
