Integrate AgentKit 0.18.1 with native authorization on macOS and iOS, device-local OAuth credentials, V43 configuration persistence, and Assistant authorization prompts.
Add HTTPS callback metadata, keep native callbacks safe across actor boundaries, and distinguish authorization setup failures from cancellation. Extend the external MCP server to negotiate 2025-03-26.
Add one-use download tickets, bounded HTTP file responses, source validation, shared transfer capacity, cancellation, and metadata-only audit.
Verification: 181 focused tests, macOS/iOS builds, Swift formatting, and Chinese localization checks passed. Full test run: 1430 tests with five failures in unchanged areas; no live-server integration performed.
Share Vault, persistence, SSH/SFTP, forwarding, and SwiftUI components across platforms. Add mobile editors, terminal input, standalone Assistant, Metrics navigation, transfers, and a unified Live Activity with host system icons.
Validation: 35 iOS tests and 100 focused macOS tests pass; formatting and zh-Hans checks pass. The full macOS run reports 14 issues in the documented timing, Keychain, and popover suites. Remaining Assistant tool and CloudKit work is tracked in Memory/MOBILE_ROLLOUT.md.
