Allow optional API keys in desktop and mobile settings and share credential
resolution across model requests. Missing stored credentials remain errors.
Enable user-configured HTTP endpoints and pin signed AgentKit 0.13.1, which
omits empty authentication headers for probes and inference.
Validation: AgentKit's 216 tests and iOS's 461 tests passed, along with Swift
formatting, localization checks, native screenshots, and real HTTP smoke tests
on both apps. macOS passed 1419 of 1422 tests initially; existing Metrics timing,
waveform PNG comparison, and MCP upload runner failures were observed. MCP and
Metrics passed a focused rerun, while Metrics remains intermittent and waveform
comparison still fails. iOS simulator LAN-IP access timed out; desktop LAN-IP
and both platforms' localhost, loopback-IP, and local-domain requests passed.
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.
