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. Source inspection shows a domain-specific x402 trust gate with documented, user-invoked network calls and configuration env reads, not stealth execution or package-install abuse. Optional paid checks require caller-provided x402 fetch/options and are aligned with the package purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-09T20:52:08.543Z - **Finished:** 2026-07-09T20:52:49.371Z - **Download time:** 260 ms - **Static scan time:** 26 ms - **AI review time:** 40540 ms - **Total time:** 40828 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 malicious attack surface. The package provides user-invoked x402 payment gating that calls TWZRD trust endpoints and can optionally use a caller-provided paying fetch for receipt/escalation checks. - **Trigger:** Import constructs default config; network activity occurs when users call exported gate/wrapper/evaluation helpers around x402 flows. - **Impact:** May block or allow caller payment flows based on TWZRD API responses; no evidence of exfiltration, persistence, destructive behavior, or install-time mutation. - **Evidence paths:** package.json, dist/index.js, dist/config.js, dist/policy.js, dist/merchant-card.js, dist/wrap-fetch.js, dist/with-guard.js, dist/auto-gate.js, dist/evaluate.js, dist/quick.js, dist/sponsored.js, dist/mcp-hook.js - **Review source:** ai\_review - **Reviewed:** 2026-07-09T20:52:49.371Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** user-invoked x402 trust preflight and optional paid receipt/quick checks - **Rationale:** Source inspection shows a domain-specific x402 trust gate with documented, user-invoked network calls and configuration env reads, not stealth execution or package-install abuse. Optional paid checks require caller-provided x402 fetch/options and are aligned with the package purpose. - **Network endpoints:** https://intel.twzrd.xyz, https://intel.twzrd.xyz/v1/intel/preflight, https://intel.twzrd.xyz/v1/intel/merchant\_card/{wallet}, https://intel.twzrd.xyz/v1/intel/quick/{wallet}, https://intel.twzrd.xyz/v1/intel/trust/{wallet} ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Runtime network calls to TWZRD intel API are present in dist/policy.js, dist/merchant-card.js, dist/quick.js, and dist/evaluate.js., dist/evaluate.js can call user-supplied x402Fetch for paid quick/trust receipt checks when opts enable escalation/autoReceipt. - **Evidence against:** package.json has no preinstall/install/postinstall hooks; only prepublishOnly build hook., dist/index.js only re-exports modules; no installer, file mutation, or agent config writes found., dist/config.js only reads TWZRD\_\* env vars for documented configuration and defaults intelBase to https://intel.twzrd.xyz., No child\_process, eval, dynamic require/import, native binaries, filesystem writes, credential harvesting, or broad persistence found., Network behavior is package-aligned: x402 trust-gate preflight, merchant-card, quick, and receipt endpoints under the configured TWZRD base. ## Affected versions and remediation This report applies to twzrd-x402-gate@0.5.0. - Review the evidence and your use of twzrd-x402-gate@0.5.0 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.
