ChaosEngineAI v0.7.2

ChaosEngineAI v0.7.2 packages everything that landed since v0.5.2 — 133 commits over two weeks. First stable release of the video generation line, alongside major work on diffusion cache compression, the Apple Silicon mlx-video runtime, the Windows installer pipeline, and a brand-new in-app Diagnostics panel. Includes ten post-tag smoke-test fixes (PRs #21–#30) that landed before the final rebuild.

Highlights

• Video Studio — full video generation tab with model picker, prompt input, runtime status overlay, real-time progress, and cancellable generation.
• Multi-engine video catalog — Wan 2.1 T2V (1.3B / 14B), Wan 2.2, Lightricks LTX-Video 2.0/2.0-distilled/2.3/2.3-distilled, HunyuanVideo, CogVideoX, Mochi, plus FLUX.1 for image.
• TeaCache diffusion cache compression — five DiT families wired (FLUX, HunyuanVideo, LTX-Video, CogVideoX, Mochi) with per-model rescale coefficients.
• In-app Diagnostics panel under Settings, with per-section error fallback and platform-aware repair actions.
• Windows installer pipeline stabilised — embedded Python sidecar + llama-server now ship in the NSIS bundle; PowerShell 5.1 build path hardened; CUDA torch DLL lock fixed; GGUF downloads scoped to lightweight base + selected quant.
• macOS Python framework switched to python-build-standalone (Astral) for reliable framework relocation.

Smoke-test fixes (post-tag, in this rebuild)

• #21 — MLX-only catalog variants (FLUX.1 Dev · mflux, LTX-2 MLX entries) hidden on Linux / Windows where mlx is not installable. New backend_service/helpers/platform_filter.py + 15 unit tests.
• #22 — Windows CUDA detection no longer reports system RAM as VRAM. Reads torch.cuda.get_device_properties(0).total_memory first; falls back to nvidia-smi; returns vram_total_gb=None when neither answers. Image-runtime probe calls importlib.invalidate_caches() so newly-installed GPU bundle packages are picked up without a full backend restart.
• #23 — Tauri NSIS installer hook (src-tauri/installer.nsh) documents the contract that %LOCALAPPDATA%\ChaosEngineAI\extras\cp{maj}{min}\site-packages must survive uninstall + reinstall. InstallLogPanel CSS establishes a stacking context so the streaming pip output renders above the Prompt + Recent Outputs cards on Windows during a long GPU bundle install.
• #24 — CI test reliability: imageDiscoverMemoryEstimate describe block pins navigator.userAgentData.platform to macOS so the MPS-calibrated expectations pass on Linux runners.
• #25 — torch.cuda probe now runs in a short-lived subprocess so the backend never holds locks on torch/lib/*.dll. Without this, pip's --target install of a fresh torch fails with [WinError 5] Access is denied. InstallLogPanel background switched to opaque var(--surface) + contain: layout so it can never visually overlap sibling Prompt / Recent Outputs cards.
• #26 — test_gpu.py accepts vram_total_gb=None as the no-GPU response (orphaned PR #24 fix landed direct).
• #27 / #28 — Tauri 2.10.3 → 2.11.0; tauri-build 2.5.6 → 2.6.0 (Dependabot Cargo bumps + Windows package version alignment).
• #29 — HunyuanVideo NF4 + 1280×720 × 33 frames CUDA estimate no longer crosses the danger ratio. Discount sliced attention to 60% of the dense fp16 8-slab estimate when CUDA + runtime override are present (real fp8-KV / attention-slicing behaviour).
• #30 — test_legacy_tauri_app_data_extras_are_import_candidates patches sys.platform = "win32" so the Linux CI runner exercises the LOCALAPPDATA branch.

Video Generation

New: Video Studio

• New Video Studio tab with model picker, prompt input, runtime status overlay, and live progress.
• Cancellable image and video generation across the app.
• Async library scan with persisted cache (library_cache.json) — startup no longer blocks on filesystem walks.
• Tooltip portal — info hovers now render via a top-level portal with viewport-clamped placement.
• Platform-aware mlx-video reinstall button in Diagnostics.
• Auto-recover Video Studio after a backend sidecar crash.
• Variant-specific video download status (sibling Q4/Q6/Q8 rows no longer marked active just because they share repos).
• Cleaned-up Video Studio runtime action layout; GPU runtime installs now recover from CPU-only torch wheels.

New: Video catalog

• Wan 2.1 T2V 1.3B / 14B (with Wan 2.2 catalog fix).
• Lightricks LTX-Video 2.0 / 2.0-distilled / 2.3 / 2.3-distilled (via mlx-video on Apple Silicon).
• HunyuanVideo.
• CogVideoX.
• Mochi.
• FLUX.1 (image).

New: Apple Silicon mlx-video LTX-2 engine

• LTX-2 (prince-canuma/LTX-2-{distilled,dev,2.3-distilled,2.3-dev}) routed through a subprocess engine — backend_service/mlx_video_runtime.py.
• Spatial upscaler resolver, distilled-pipeline accounting, dist-info cleanup.
• Real LTX-2 module path + corrected CLI flags.
• LTX-2 MLX download false-positive fix + LTX prompt-length hint.

New: stable-diffusion.cpp engine scaffold (cross-platform)

• Binary staging in scripts/stage-runtime.mjs; path resolution in src-tauri/src/lib.rs (resolve_sd_cpp + CHAOSENGINE_SDCPP_BIN_DIR).
• Engine class SdCppVideoEngine in backend_service/sdcpp_video_runtime.py.
• Manager exposes sdcpp_video_capabilities() so Setup / Studio can surface staging state.

New: LongLive scaffold (CUDA only)

• Real-time causal long video generation for Wan 2.1 T2V 1.3B.
• Install path — collapsible terminal panel for streaming progress, hang fix on Windows.
• Discover Install CTA in Video Studio.

Quality + safety

• Phase E1 — auto-enhance short video prompts with model-tuned suffixes.
• Phase E2 — CFG decay schedule + extend prompt enhancer to LTX-2 family.
• Three Phase E2 regressions caught on real Mac runs.
• Tuned video safety estimator + LTX-2 subprocess error visibility.
• Improved video gen quality across LTX / Wan / HunyuanVideo + new engine scaffolds.
• Scale video gen safety by device memory and show Studio capacity.
• Detect corrupt diffusers snapshots, add output-folder pickers, MPS-safe defaults.
• In-app install for mp4 encoder deps; isolated video output dir in test harness.
• HunyuanVideo NF4 + 1280×720 × 33 frames now lands on caution rather than danger on a 4090; long-clip danger warnings still trigger for genuinely risky configs.

Cache compression for diffusion DiTs (TeaCache)

• TeaCache integration with vendored teacache_forward patches under cache_compression/_teacache_patches/.
• Five model families wired: FLUX, HunyuanVideo, LTX-Video, CogVideoX, Mochi.
• Per-model rescale coefficients pulled from upstream calibration tables.
• Quality knob rel_l1_thresh (default 0.4).
• TeaCache strategies are filtered out of the LLM RuntimeControls picker via the appliesTo domain field.

Memory + warm pool

• Memory-budgeted warm pool + library-only chat picker.
• Improved model catalog UX and memory estimates.
• Base LLM library RAM estimate on real on-disk size.
• Include model footprint in video gen memory estimate.
• Fix TurboQuant install detection + warm pool memory guard.
• Show release dates and accurate on-disk sizes across model listings.

Diagnostics + Settings UI

• New in-app Diagnostics panel under Settings with per-section error fallback.
• Reject load_model for models not on disk; disable chat Send until loaded.
• Rename dashboard engine label from "No backend" to "Idle".
• Split Settings page into logical sections with sub-navigation.
• Drop the side-menu Settings layout, always use the tab bar.
• Redesign the Storage section and surface resolved paths.
• Diagnostics: catch find_spec on missing namespace + scroll body.
• Fix Diagnostics panel scroll on tall viewports + long path wrapping.
• Tabs-mode sidebar, SubtabBar, and Settings → Appearance toggle.
• Group sidebar tabs into Models / Images / Benchmarks / Tools with SVG icons.

Windows pipeline

• Ship embedded Python + llama-server in the installer — no source checkout needed at first launch.
• Fix Windows restart deadlock.
• PowerShell 5.1 hardening — strip non-ASCII, drop &&, avoid backslash-before-paren, strip apostrophes / ampersands.
• Stop the video runtime probe timing out on Windows.
• Stabilise the Windows dev/build loop and surface CUDA-vs-CPU torch detection.
• Unblock Windows video / image studios during first-boot torch import.
• Warn on CPU fallback and stop Video Studio stalling on Windows.
• Stop build.ps1 dying on git checkout's success message.
• Fix LongLive install on Windows.
• Real CUDA VRAM detection via torch.cuda (was reporting 12 GB on a 24 GB RTX 4090).
• Image-runtime probe re-checks importable packages after a GPU bundle install.
• CUDA torch clobber + DLL lock during GPU bundle install fixed (subprocess probe).
• Persist installed runtime path across backend restarts; auto-restart when required.
• Logical install package counts reported correctly.
• GGUF video downloads fetch only the lightweight base pipeline + the selected quantized transformer file.
• Windows test + runtime edge cases for directory sizing, library fingerprints, path formatting, optional GGUF import failures.
• Tauri 2.10.3 → 2.11.0; tauri-build 2.5.6 → 2.6.0 alignment.

macOS Python framework

• Switched to python-build-standalone (Astral) so @loader_path / @rpath references are baked in — avoids the install_name_tool regression with Xcode 16.4 + actions/setup-python that previously crashed at launch with Library not loaded: Python.framework.
• Persistent extras dir namespaced by Python ABI ...
