Arc-style spaces, and the first agent sessions
Spaces got colour, ordering and a swipeable strip driven by real trackpad phases. Realm also ran its first agent session, on the Claude adapter.
The sidebar became a space strip you can swipe between, driven by native trackpad phases through a CGEventTap rather than by accumulated wheel deltas, so it tracks a finger the way macOS Spaces does and can be reversed mid-gesture.
Underneath, the first agent session: an adapter interface, a message mapper, a sessions store and a session pane with a transcript, tool cards, permissions and a composer.
Session status reached the sidebar, titles came from the first message, and a permission left dangling by a relaunch stopped blocking the session it belonged to.
