 ## Milestone 4 - Interactive SSH Session UX
 
-Status: In Progress
+Status: Completed
 
-Started:
-- Milestone 4 draft added to spec
-- Interactive SSH terminal panel wiring started (backend output stream + input send path)
-- Host-key confirmation request/response signal flow added (`Ask` policy path)
-- `known_hosts_policy` defaults and profile dialog options updated to include `Ask`
+Delivered:
+- Embedded interactive SSH terminal using `KodoTerm` + vendored `libvterm`
+- Native in-terminal typing for SSH sessions (no separate input box)
+- ANSI/color rendering with selectable terminal themes (`Dark`, `Light`, `Solarized Dark`)
+- Cross-platform SSH auth path improvements (`ssh-askpass` handling and host-key policy wiring)
+- Session UX simplification: auto-connect on tab open, disconnect on tab close
+- Tab-state indicators via tab color and state suffix (`Connecting`, `Connected`, `Disconnected`, `Failed`)
+- Right-click tab menu for `Disconnect`, `Reconnect`, `Theme`, and `Clear`
+- Collapsible events panel retained as primary diagnostics surface; inline detail/status banners removed
+- Terminal behavior polish: better fixed-width font selection, cursor visibility, backspace handling, and terminal-size negotiation stability
 
-Pending:
-- End-to-end interactive behavior hardening across Linux/macOS/Windows
-- Terminal UX polish (control keys, resize behavior, output formatting)
-- Additional diagnostics and integration test coverage for reconnect/auth/host-key scenarios
