v6.0.0-rc.2

Fixed

• Native Tab V2 buyer and seller admission now completes at Solana confirmed after independently fetching the exact successful reservation transaction, verifying its Dexter-authority-signed voucher-binding Memo, and reading coherent Vault/SessionAccount state anchored to that transaction slot. Paid requests no longer wait for finalization; processed-only evidence still fails closed.
• V2 seller channel binding can no longer be poisoned by a scope-rejected first request, a concurrent competing registration, lease refusal, or a downstream durable-ledger failure.

Unchanged safety boundaries

• Rollback, failed-transaction retirement, blockhash-expiry adjudication, close, and revoke retain their finalized/background boundaries. A later finalization preserves the already-issued confirmed receipt byte-for-byte.
