 ## P2 dock shell
 
 The main window now behaves as a compact engineering shell rather than a fixed
-form. Signal Preview is a right-side dock that can be hidden or detached into a
-real secondary Qt window. Status History and Output Monitor share a collapsible
-bottom dock so runtime evidence stays visible without displacing the manual
-injection grid. The Views menu restores closed panels and detaches Preview.

+form. Engineering source, profile, scaling, quick setup, and runtime details
+live in a dedicated Smart / Expert Configuration window instead of consuming
+permanent space beside the injector. Phasor View and Waveform View are separate
+right-side docks; each can be hidden or detached into its own real Qt window.
+Status History and Output Monitor share a bottom dock that starts collapsed.
+The View ribbon restores closed panels, detaches either plot, and expands the
+bottom monitor.
+
+The shell uses nested draggable splitters: editor vs preview docks, Phasor vs
+Waveform, and workspace vs bottom monitor. Every pane keeps a protective
+minimum size, while its split can be resized directly like an engineering MDI
+shell. The complete monitor header is clickable for smooth expand/collapse.
+
+Smart mode is the default and guides device recognition, PTP inspection, and SV
+profile selection. Expert mode exposes the detailed SV profile compiler plus
+bounded PTP domain, transportSpecific, VLAN, interval, and peer-delay controls.
+Deploy and Start remain disabled until the serial response proves the connected
+port is the ARStack ESP32-P4 injector.
+
+PTP remains explicitly labeled as a laboratory timing companion. The firmware
+serial surface now supports `PTP SHOW`, `PTP START`, `PTP STOP`, and bounded
+`PTP CONFIG`; none of these claims external grandmaster lock or changes the
+truthful `smpSynch` boundary.
+
+The safety-critical editor remains the stable center pane. Split sizes are
+operator-adjustable, while arbitrary drag-reordering and layout persistence
+remain follow-up work; detaching a view must never move or duplicate the output
+controls.
