v2.0.0-alpha.30

This prerelease adds local completed-result recovery and explicitly authorized replacement attempts for tool-free structured requests. It does not resume a remote provider stream. See the verification report.

Added

• Added opt-in recovery for ephemeral, tool-free structured requests: frozen account-bound requests, durable attempt accounting, host authorization before each generation POST including authentication reissues, and local completed-result receipts that survive relaunch. This supports explicit replacement generations, not remote stream resumption. See structured request recovery.
• Added typed Responses interruption metadata including provider response ID, sequence cursor, output/tool activity, and underlying transport error domain/code.
• Added signed iOS/macOS demo comparisons for dropped connections and receipt retrieval in a second app process with zero generation requests.

Fixed

• Ignore repeated numbered stream events and repeated function-call IDs within a turn; reject conflicting repeated tool arguments. Tool deduplication does not extend across new requests or app restarts.

Changed

• Responses transport URL failures now surface as AgentRuntimeError with typed interruption and retry information. Callers that catch only URLError should inspect interruption.transportErrorCode.
