Enforce gpt-image-2 for publication-material workflows to ensure stable, predictable promotional asset generation. Updates include: docs clarifying the decision and UI behaviour; backend api-server normalize/force model to GPT_IMAGE_2 for kind = "publication-material"; frontend sets publication dialogs to use and display a disabled gpt-image-2 model capsule and computes cost using that model; submission flow no longer remembers or submits nanobanana2 for publication items. Added/updated unit tests and a demo panel test to validate the locked model. Key files changed: docs/* (decision log and editor guides), server-rs/crates/api-server/src/editor_project.rs, several src/components/image-editor/* files and tests.
Handle character-action generation results as real video assets: use backend previewVideoPath as layer src, set mediaType="video" and assetKind="character-animation", and store the first frame only as thumbnail/poster. Update docs to document the new behavior and preserve backend frame extraction/green-screen workflows. Update UI/UX: compact parameter labels (e.g. "16:9·1K"), quick-edit treats original image as an implicit last reference (hidden from the reference bar) and allows editable bottom capsules, and ensure exports preserve true media file types. Change upload toolbar icon to Upload and add tests to cover the icon and video-layer behavior; also add serialization/hydration test for video thumbnails and adjust many integration/unit tests to reflect new labels, sizes and generation semantics. Files touched include multiple docs under docs/, edited components and tests under src/components/image-editor/, and minor stylesheet updates.
Unify UI aliases for the Nanobanana image model by mapping display and legacy names to the real model ID (gemini-3.1-flash-image-preview). Added normalizeEditorImageModel and used it across generation, dialog, submission and workflow code paths to ensure consistent model selection and pricing. Server-side editor_generation_config and editor_project were updated to accept the display alias (nanobanana2) and legacy alias (nano-banana) for validation/pricing. Tests and docs were added/updated to cover alias normalization and related UI behavior; minor code formatting tweaks included.
Adds Seedance 2.0 reference-media constraints and forbids video data URLs; updates docs/decision-log and pitfalls to record the new rules. Introduces typed audio params (type: one-shot|loop, tempo: number|null), generator-specific placeholder styles/avoidance and UI changes for generation panels. Implements related front-end changes (new crop/ raster edit components, many image-editor models, tests and workflow hooks) and server-side contract/handler updates across api-server, shared-contracts, platform-audio, platform-image and vector_engine_audio_generation to support the new submission/asset flow and validations.
Add unified placement and UI updates for canvas generation: docs require ImageCanvasGenerationPlacementModel to compute placeholder positions (avoid overlaps, center viewport on placement) and limit frontend video model entries. Refactor UI components and tests: expose div props on PlatformFloatingMenu, make PlatformInlineOptionButton forwardRef, replace inline placeholder actions with ImageCanvasGenerationImageOptionsView in basic generation composer, enhance character animation panel with parameter menu portal and option choices, add reference chip UI, and update many tests to match new interactions and labels. These changes align generation workflows, accessibility labels, and positioning behavior across editor panels.
