 ## Milestone 5 - RDP Fully Working
 
-Status: Planned
+Status: Completed
 
-Planned Scope:
-- Replace current unsupported RDP path with complete RDP implementation
-- Deliver usable in-app RDP session behavior aligned to SSH UX
-- Implement RDP connect/disconnect/reconnect lifecycle handling
-- Extend profile/session connect options needed by RDP
-- Standardize event log and error mapping behavior with SSH
+Delivered:
+- Added `RdpSessionBackend` and wired protocol selection so `RDP` no longer routes to unsupported backend
+- Pivoted RDP design to embedded-only integration (no external RDP process launches)
+- Implemented embedded FreeRDP client thread with connect/disconnect lifecycle and event-loop handling
+- Added in-window `RdpDisplayWidget` rendering surface with frame updates from FreeRDP GDI
+- Wired direct keyboard/mouse input from the embedded RDP surface to the backend
+- Added RDP connect-time password prompt flow and settings wiring (host/port/user/password, desktop size)
+- Added explicit profile `Domain` support for RDP auth (with `DOMAIN\username` fallback parsing)
+- Updated session tab/context-menu behavior so terminal-only actions are hidden on RDP tabs
+- Implemented dynamic in-session RDP resolution renegotiation from viewport resize events
+- Enabled minimal FreeRDP client-channel build (`drdynvc` + `disp`) and channel loading for runtime resize support
+- Added RDP profile-level security mode and performance profile options, wired into FreeRDP connection settings
+- Hardened RDP lifecycle handling for disconnect/reconnect/abort flows to avoid false failure states on user-initiated stops
+- Expanded RDP error/disconnect diagnostics with richer FreeRDP code mapping and raw disconnect detail events
+- Pulled FreeRDP source for integration planning and API review
