Atelier 1.6.1-rc.1 - quality fixes preview

This preview fixes defects found while inspecting actual AI edits and video previews. Final GPU quality validation remains unfinished; this is not a visual-quality sign-off.

Changes:

• Align video selection previews with the first processed frame, including fractional seeks.
• Preserve shading and alpha in video tint instead of flattening the image with a color overlay.
• Add explicit Director removal controls, expanded shadow context and protection for nearby foreground objects. Painted mask boundaries remain fixed.
• Preserve cancellation status and saved attempts when the game guard interrupts a run.
• Strengthen AI review prompts for material changes and removal ghosts.

Validation: 107 backend tests and 30 frontend behavior checks pass locally. The refined 24-frame CPU tint preview was inspected frame by frame and checked for protected pixels, original audio, full decode, lossless export and muted playback.

Known limits: optical-flow mask holes and H3 material changes remain. The new automatic removal path, the SAM/H3 moving-video case and a SAM-tracked tint comparison still need GPU validation. See quality status.

Atelier H3 Image Editor 1.6.0

A local image and short-video workspace with searchable tools, clearer CPU/GPU controls, AI Director, ComfyUI and optional LM Studio vision.

Connects image compositions to H3 Prompt Studio 1.7.1 as separate video drafts.

Download the ZIP, extract it, then follow README.md. Windows: Setup.ps1 then Launch.ps1 -OpenBrowser. Model weights and ComfyUI are separate installations; see docs/MODELS.md. Linux defaults to CPU mode.

Validated: 98 Python checks on Windows and Linux, 30 frontend checks, a real CPU tracked-video round trip with audio and full decode, browser UI and real H3 draft transfer. GitHub CPU CI passed. No new GPU inference was run during this release pass. AI review can miss defects, and H3 video edits remain short frame-based previews.
