Verification on September 10, 2026

• Clean clone at the pinned commit: typecheck, 35 unit tests, reference-server smoke test and demo structure smoke test passed.
• Private-import boundary check passed.
• Public demo and brief returned HTTP 200.
• Published video decoded in the browser: 1440 × 900, 78.88 seconds, no media error.
• Historical public proof returned matched: 17 input + 256 output tokens, 1 atomic USDC settled.
• Historical Monad Testnet transaction.

Scope and limitations

This is a Developer Preview, not audited production custody software. The public reference merchant uses process-local storage; production crash durability requires a transactional adapter.

The walkthrough is an interactive simulation with a scripted, locally tested repair. Its payment evidence comes from the September 7 model request. That request did not generate the teaching fixture. This release does not claim a new paid model-generated repair or a completed Metropolis submission.

The browser wallet operator is experimental. A new paid run and live recovery have not been verified for this pinned release; current local recovery changes are not part of this release. Do not treat local tests as evidence of successful live recovery.

The owner policy bounds AgentPay-authorized spending; it does not restrict all unrelated transactions from an ordinary EOA. Toolkit and aiplans.dev are existing products; this release contains the AgentPay-specific public implementation, not the private Toolkit SaaS control plane.
