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 payment-safety library with user-invoked network and subprocess behavior aligned to its x402 trust-gate purpose, not install-time execution or covert data theft. The suspicious primitives are opt-in runtime/CLI paths with package-specific endpoints and no unconsented agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-07-10T08:18:33.818Z - **Finished:** 2026-07-10T08:19:35.032Z - **Download time:** 253 ms - **Static scan time:** 83 ms - **AI review time:** 60877 ms - **Total time:** 61214 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 was established. Runtime behavior is an explicit x402 payment trust gate/CLI that calls package-aligned TWZRD endpoints and may invoke AgentCash only when the user runs the CLI. - **Trigger:** User imports wrappers/hooks or runs twzrd-safe-fetch CLI - **Impact:** Blocks or allows user-initiated x402 payments based on TWZRD policy; no exfiltration or persistence identified - **Evidence paths:** package.json, bin/twzrd-safe-fetch.js, dist/safe-fetch.js, dist/config.js, dist/policy.js, dist/merchant-card.js, dist/evaluate.js, dist/with-guard.js, dist/wrap-fetch.js, dist/mcp-hook.js, dist/x402-client-hook.js, dist/auto-gate.js - **Review source:** ai\_review - **Reviewed:** 2026-07-10T08:19:35.032Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** x402 payment preflight and optional paid trust check - **Rationale:** Source inspection shows a payment-safety library with user-invoked network and subprocess behavior aligned to its x402 trust-gate purpose, not install-time execution or covert data theft. The suspicious primitives are opt-in runtime/CLI paths with package-specific endpoints and no unconsented agent control-surface mutation. - **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/{sellerWallet}, https://intel.twzrd.xyz/v1/intel/trust/{payTo} ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** bin/twzrd-safe-fetch.js uses child\_process spawnSync only as a dev fallback when dist is absent, dist/safe-fetch.js can spawn npx agentcash@latest fetch after explicit CLI invocation and TWZRD approval, dist/evaluate.js optionally calls paid TWZRD quick/trust endpoints when caller supplies x402Fetch and opts in - **Evidence against:** package.json has no install/preinstall/postinstall hooks; only prepublishOnly build hook, dist/config.js defaults network calls to package-aligned https://intel.twzrd.xyz and env overrides are TWZRD-specific, dist/policy.js posts payment metadata to /v1/intel/preflight for trust gating; no credential/env/file harvesting found, dist/with-guard.js, dist/wrap-fetch.js, dist/mcp-hook.js, and dist/x402-client-hook.js gate x402 payments before signing instead of mutating agent config, No file writes, persistence, broad AI-agent control-surface mutation, eval/vm, or native/binary loading found ## Affected versions and remediation This report applies to twzrd-x402-gate@0.5.2. - Review the evidence and your use of twzrd-x402-gate@0.5.2 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.
