jcode-routed Codex adapter (Antigravity/Cursor stayed on their dedicated adapters per Phase 0's empirical spike - jcode 429s where the native agy/cursor-agent binaries work), agency-agents subagent picker synced into Claude Code's own agents dir, and a full Apple HIG sidebar rework of the app UI (fixes a dark-mode color byte-order bug, adds a macOS System Settings-style sidebar nav, consistent button/card styling). 146 tests green.
