v0.1.0-alpha.8

Alpha.8 introduces two exact-payment profiles for Kaspa x402.

• standard-native is the default exact profile.
• Optional KIP-10 additive exact uses the successor delta as the sole merchant payment.
• Durable reusable head pools replace consumable reservations.
• Payer request authorization, bounded retries, trusted reconciliation, replay protection and recovery checks are strengthened.
• The alpha.7 batch-settlement lifecycle remains supported.

The complete release gate passes with 357 tests, Rusty Kaspa 2.0.1 consensus vectors, SilverScript fixtures, browser and Worker checks, offline proofs, funded TN10 evidence, clean registry imports and zero production dependency vulnerabilities.

The public npm packages are available at 0.1.0-alpha.8 under the alpha dist-tag.

The hosted alpha.8 Worker was deployed from follow-up commit 37a4704 after the release tag. Its funded standard-native canary settled transaction 198191204a1b1cc5ab79e56d83621f8cf880358ef970adf545379e0b9e3584f9 at accepted finality, returned the protected resource, replayed idempotently, and rejected cross-resource reuse. The tag remains immutable; these operational follow-ups are recorded on main.

This remains alpha software for Kaspa Testnet 10. Mainnet spending and broadcast remain disabled.
