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.
Move editor generation pricing to backend: remove priceMudPoints from public request schemas and docs, require backend to compute model prices and perform pre-charge via execute_billable_asset_operation_with_cost. Update character animation and video handlers to use authenticated owner IDs and wrap generation requests in billing; remove client-side price validation. Adjust OpenAPI, project-memory docs, pricing management docs, and related tests to reflect that front-end only displays prices and must not submit priceMudPoints. Also document new user registration reward and wallet refund outbox behavior. Code and test changes applied across api-server handlers, shared contracts, and image-editor client/tests.
Introduce a new detailed Agent handbook (docs/【协作规范】Agent工作入口与执行准则-2026-06-22.md) and refactor AGENTS.md to be an entry-only navigation page. Update documentation cross-references (docs/README.md, project-memory README, document-map, team-conventions, development-workflow, decision-log and project-overview) to point to the new file and clarify reading/order rules, submission/validation constraints, and SpacetimeDB/back-end wording. Also adjust image canvas generation placement rules in the frontend doc and apply related changes to image-editor hooks/tests (src/components/image-editor/*). Purpose: separate high-level entry rules from complex execution details to reduce startup cost for complex tasks and centralize execution practices in a single guideline document.
Remove explicit cancel callback and centralize dismissal: clicking the canvas now dismisses active UI extraction (handled in ImageCanvasEditorView) instead of relying on an onCancel prop. Simplify ImageCanvasStageView and ImageCanvasUiAssetExtractionOverlayView APIs by removing onCancel and related UI. Improve preview bounds and rendering: add normalization to mark bounds, clamp to source dimensions, and render crop previews using an absolutely-positioned <img> for accurate, coordinate-based previews. Update styles for toolbar active states and preview image layout, and reduce SVG stroke width. Update tests and docs to reflect new behaviors and UI wording (tool highlight, accurate crop preview, and dismissal behavior).
Unify and lower default mud-point prices across editor generation features and update related API/schema, docs and tests. Changes set gpt-image-2 to 1K=3 / 2K=5, audio1.0 to 5, and chirp-v5 to 12, and update server default JSON, frontend models/workflows, OpenAPI schema (require aspectRatio/imageSize/priceMudPoints for UI extraction), multiple UX docs (quick-edit viewport, UI extraction panel, pricing guidance) and accompanying tests to match the new defaults and validation rules.
Require an explicit red-box selection before extracting UI-design assets: add rectangular/ellipse/brush selection UI, render red-outline marks into a marked Data URL on the client, and update the extraction prompt to "仅提取被红色框框选的素材并整理成spritesheet". Add frontend overlay/raster models and tests to support the selection flow and adjust numerous image-editor tests and views to wire up the selection lifecycle. On the dev ops side, enhance scripts/dev to detect a local %LOCALAPPDATA%/Genarrative/ffmpeg/bin installation on Windows, prepend it to PATH and inject CHARACTER_ANIMATION_FFMPEG_PATH/FFPROBE_PATH (with tests), and export the helper. Server config now prefers GENARRATIVE_*-prefixed FFmpeg env vars and includes a Rust test to validate reading the prefixed variables. Update docs to describe the new UI extraction behavior and local FFmpeg handling.
