Host or attach the asset service, archive generated and terminal outputs, and provide image/video/audio/text/3D viewers with fullscreen and gallery navigation. Load only visible bounded previews, generate video posters and text excerpts, and normalize legacy thumbnails off the UI thread.
Expose video frame counts and Sandbox chat providers, make failed queue cleanup idempotent, compact the panels, and correct short-wire direction. Replace App view with a movable, resizable CodeEditor overlay with debounced source saves, live graph updates, invalid-source preservation and close/reopen geometry.
Validation: release Flow, Flow UI and flowgraph suites passed 335 tests (two ignored). Updated Flow UI suite passed 107 tests; asset route suites passed nine tests after legacy preview fixes. The rebuilt release app passed remote editing, dragging, resizing, invalid-source, close/reopen and App removal checks; final All assets scrolling measured 16.5 ms median and 18.3 ms maximum over 12 inputs. Test instances were closed through the remote protocol.
Model and format pickers, the inspector's one-of rows, the Ask face's
choice and face-declared pickers all render as ComboBox; the popup and
its input map through the canvas zoom. ComboBoxRef gains changed_label
and set_selected_by_label so the bindings did not have to change shape.
