Adds the ability to manage multiple Hermes installations — local and remote over SSH — from the same Scarf app, each in its own window. Architecture: - ServerContext value type carries per-server identity + paths through every VM and service. ContentView routes serverContext into each feature view's init; all 22 routed views thread it through to their @State VMs. - ServerTransport protocol with LocalTransport (FileManager/Process/ FSEvents) and SSHTransport (system ssh + scp + ControlMaster). Services were ported from direct Foundation I/O to transport-routed helpers so the same code runs against local or remote. - WindowGroup(for: ServerID.self) gives each window its own AppCoordinator + HermesFileWatcher + ChatViewModel. File menu has Open Server commands with keyboard shortcuts (⌘1..⌘9). MenuBarExtra fans out per-server with start/stop/restart controls. - ServerRegistry persists connections to ~/Library/Application Support/scarf/servers.json. Add Server sheet probes the remote with ssh -v to capture the full handshake on failure. - Connection-status pill in remote-window toolbars with silent reconnect (3s retry on first failure, escalate to red after 2 consecutive), known-hosts-mismatch + ssh-add hint cards with copy buttons. Concurrency / UX hardening (the parts learned the hard way during dogfooding — captured in the feedback memory): - ServerContext exposes context.readText / readData / writeText / fileExists / runHermes / openInLocalEditor as the canonical I/O surface. Every VM uses these; never raw FileManager / Process() / NSWorkspace.open with a Hermes path. - SSHTransport.remotePathArg rewrites ~/foo to "$HOME/foo" so paths expand correctly inside the sh -c command we build (POSIX shells don't expand ~ inside any quotes). - Heavy VM load() methods detach to a background task and commit results back via MainActor.run, so synchronous ssh round-trips don't beach-ball the UI. Applied to Dashboard, Memory, Settings, MCPServers, Cron, Plugins, Personalities, QuickCommands, Skills, Gateway, Health, CredentialPools. - LoadingOverlay modifier shows a spinner over empty/stale section content during background reloads. - enrichedShellEnv (zsh -l -i probe, up to 8s) is now warmed at app launch off-main so first MainActor caller doesn't block. - Drop the file watcher's 5s heartbeat — FSEvents covers real changes and the heartbeat was triggering wasted reloads across every subscribing view. Chat polish: - ChatViewModel.hermesBinaryExists is a stored bool probed once at init, not a sync transport call evaluated on every body re-render. - MessageGroupView identifies assistant bubbles by array offset rather than message.id, so the streaming → finalized id transition no longer destroys + recreates the bubble. - Static scroll anchor in RichChatMessageList prevents two onChange handlers from racing on isWorking flips. Branch state: feature complete, in active dogfooding. Plan + per-phase status live at ~/.claude/plans/we-developed-an-application-harmonic-stroustrup.md; the four hard-won transport/concurrency rules are saved in the ServerContext-pattern feedback memory for future sessions.
