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 flagged wallet transfer occurs in the explicitly invoked fund command and requires a source key and recipient. Client-side payment handling is part of the package’s stated purpose and applies mandate, spending, and token checks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-11-01T05:09:38.021Z - **Finished:** 2026-11-01T05:10:05.676Z - **Download time:** 774 ms - **Static scan time:** 390 ms - **AI review time:** 26490 ms - **Total time:** 27655 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; transfers and payment signing serve the package’s stated payment purpose. - **Trigger:** A user runs a CLI command or an application makes a payment-aware client request. - **Impact:** Funds may be transferred or spent within the user-configured payment flow and its limits. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T05:10:05.676Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CLI transfers require explicit source and recipient arguments; client payments are constrained by a mandate and recognized token checks. - **Rationale:** The flagged wallet transfer occurs in the explicitly invoked fund command and requires a source key and recipient. Client-side payment handling is part of the package’s stated purpose and applies mandate, spending, and token checks. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports its client library; the CLI is a separate executable entry point., The fund command requires an explicit source key and recipient before sending funds., Automatic challenge payments check mandate expiry, allowed realm, and spending limits., EVM payments require a mandate owner and a token recognized by the client. ## Affected versions and remediation This report applies to paidwithtab@2.4.0. - Review the evidence and your use of paidwithtab@2.4.0 before allowing it.
