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.
The 5090 listed flux2-dev ready (total VRAM passed the gate) then refused
every job (29696 + 2048 reserve > ~30510 usable); the flow picked it by
domain ETA and never retried. Nodes now publish vram_usable_mb and mark
un-admittable models too_small; the fleet gate uses usable VRAM; the
flow's gen executor picks admitted nodes for the requested model (ready
first), retries up to three nodes after an admission refusal, and when no
node can take the model its error says why per node (role, too small with
the numbers, waiting for VRAM). The flow's model listing drops (model,
node) pairs the node's fleet role bars, so the picker no longer counts the
chat-only PRO 6000 as ready for image; its label reads ready/absent/too
small with the GPUs named.

Real adapters by default (HubChat, FleetGen, HubHttp); seams for tests; the
gen path is proven end to end against the in-process testpattern hub service.
