Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 13 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:** 0.9.11 - **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 has no install hook, and the library entry point only exports modules. The flagged process execution and fixture request serve explicit CLI flows consistent with the package’s payment-gating purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-31T01:21:38.029Z - **Finished:** 2026-10-31T01:22:20.321Z - **Download time:** 780 ms - **Static scan time:** 726 ms - **AI review time:** 40784 ms - **Total time:** 42292 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 identified; payment and network actions are exposed through user-invoked commands and the package’s intended payment-gating flow. - **Trigger:** A user runs a payment CLI or the refusal demo; package installation and library import do not trigger those actions. - **Impact:** No unauthorized collection or action was identified. An explicitly run safe-fetch command can make a payment if the gate approves and the payer accepts the challenge. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T01:22:20.321Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The safe-fetch command checks a request with the configured TWZRD preflight, blocks when approval is false, and invokes AgentCash only after approval and outside dry-run mode. - **Rationale:** The manifest has no install hook, and the library entry point only exports modules. The flagged process execution and fixture request serve explicit CLI flows consistent with the package’s payment-gating purpose. - **Network endpoints:** https://intel.twzrd.xyz/v1/intel/preflight, https://intel.twzrd.xyz/v1/intel/refuse-fixture ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest declares \`prepublishOnly\` for release verification and no install-time hook., The package entry point exports library modules; I found no automatic import-time action., The safe-fetch flow returns a blocked result when payment approval is false., The AgentCash subprocess is part of the safe-fetch payment flow and runs only after approval and unless dry-run is enabled. - **Evidence against:** The safe-fetch CLI can run \`npx agentcash@latest fetch\` after its preflight approves a user-supplied request., A separate refusal demo contacts the package’s own \`intel.twzrd.xyz\` service using a fixed fixture. ## Affected versions and remediation This report applies to twzrd-x402-gate@0.9.11. - Review the evidence and your use of twzrd-x402-gate@0.9.11 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.
