Adjust the Chinese prompt text in build_editor_character_image_prompt to clarify instructions: emphasize generating a character illustration based on the role description, rephrase the visual-spec reference, and separate/clarify the prohibitions (keep centered composition, green-screen background, and disallow non-character scene elements). This is a wording/clarity change only; no functional logic was modified.
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.
