DEAS 0.2.21 BETA — AMD Linux backend, H3 clean-VAE, preview & confirm fixes

DEAS 0.2.21 BETA

New & fixed

• AMD Radeon (Linux) can now run DEAS's owned ComfyUI backend: RDNA2–RDNA4 detection in setup, pinned ROCm environment, real-computation GPU verification. RTX Video refine and RTX frame generation stay NVIDIA-only and are refused at submit with a named reason. NOTE: this AMD path is declared, not yet verified support — development happened without an AMD card, so the first real RDNA card is the acceptance gate.
• MiniMax H3 now auto-picks the clean blending video VAE; installing the fast Sol window decoder no longer silently becomes the default and paints 128/256-pixel seam lines into every frame. The Sol decoder stays selectable by hand.
• The enhanced video preview plays as a video again — the companion's fragmented-MP4 animated previews are accepted and fed to the looping player instead of falling back to a still image.
• Consent popups now sit on top of the video preview (real in-app dialogs; the native preview steps aside while a dialog is open).
• Comparing models in the same family keeps your settings: switching between two H3 checkpoints no longer resets steps/CFG/sampler/scheduler/size.

Assets & provenance

• Source commit: 86601cb (tag v0.2.21)
• deas-linux-amd64: local CachyOS build (rust 1.94), direct-run glibc floor 2.39, ldd clean — built on this machine, UNSIGNED.
• deas.exe: MSVC cross-compile via cargo-xwin (LNK4099 missing-debug-info warning is benign), WebView2 runtime required. A cross-compiled exe is not Windows runtime-accepted; first real Windows launch is the acceptance test.
• No NSIS installer / deb / AppImage in this fallback (no native Windows runner / patchelf bundling); four-asset set only.
