twzrd-x402-gate@0.9.13

Security fixes: payment-verdict integrity issues fixed through 0.11.4 (see the 0.11.2, 0.11.3 and 0.11.4 changelogs). Upgrade to twzrd-x402-gate@0.11.4.

Released identity 0.9.13. Buyer-side x402 trust gate: free preflight before signing USDC to a merchant. On Solana mainnet and Base mainnet (eip155:8453), a missing payTo is not approved, a buyer preflight outage does not sign unless TWZRD_FAIL_OPEN=true,

The flagged subprocess runs only in a user-invoked CLI flow, and the package documents that its two-request preflight is advisory. Default delivery capture sends payment metadata to the package's intel service, with opt-out switches documented in the published API declaration.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user invokes a CLI or calls a payment integration.

Impact

No unauthorized install-time or import-time action, credential collection, or payment action was identified. The CLI documents its challenge-binding limitation.

Mechanism

The CLI probes a user-supplied URL, requests TWZRD preflight, and may invoke AgentCash. Delivery capture sends documented payment metadata and has opt-out switches.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest has a prepublishOnly release check, but no install, preinstall, or postinstall hook.
The package entry point exports APIs; the safe-fetch CLI runs its main function only when invoked as a CLI.
The safe-fetch source labels its preflight advisory and warns that AgentCash may receive a different payment challenge on its second request.
The CLI requires a user-supplied URL; its AgentCash subprocess is part of the explicitly invoked payment flow.
Delivery capture reports payment metadata, not response bodies, and the published API declaration documents opt-out switches.

Evidence against

When the user invokes the payment flow, the CLI runs npx with agentcash@latest.
Delivery capture is enabled by default and sends merchant and settlement metadata to the TWZRD intel service.
