Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 5 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:** 1.0.0-next.382 - **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 manifest contains no lifecycle hooks, and its entry points expose transport utilities without performing a connection on import. Socket and messenger activity is initiated through consumer-called APIs and serves the package’s stated VS Code data-client purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-11-01T19:44:26.291Z - **Finished:** 2026-11-01T19:44:47.188Z - **Download time:** 520 ms - **Static scan time:** 78 ms - **AI review time:** 20298 ms - **Total time:** 20897 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 attack was identified. The package provides VS Code messenger and local data-server connection utilities. - **Trigger:** No install-time or import-time action was identified; socket connection begins when a consumer calls the connection API. - **Impact:** No unauthorized data collection, account action, persistence, or destructive behavior was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T19:44:47.188Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The caller-provided messenger relays protocol messages to a socket, which defaults to 127.0.0.1 and accepts a caller-supplied port and optional host. - **Rationale:** The manifest contains no lifecycle hooks, and its entry points expose transport utilities without performing a connection on import. Socket and messenger activity is initiated through consumer-called APIs and serves the package’s stated VS Code data-client purpose. - **Network endpoints:** 127.0.0.1 (default socket host; caller may provide a different host) ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines package entry points and exports, with no install, preinstall, or postinstall hook., The listed scripts are build, clean, lint, test, watch, and a prepack packaging guard., The socket transport is created by an exported function and defaults to connecting to 127.0.0.1; the caller supplies the port and may supply a host., The connection function relays messages between the caller-provided webview messenger and the data-server socket. ## Affected versions and remediation This report applies to @hydranium/data-client-vscode@1.0.0-next.382. - Review the evidence and your use of @hydranium/data-client-vscode@1.0.0-next.382 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.
