 - `sliceWarning` is a separate condition used only when transparent spritesheet post-processing succeeded but automatic slicing failed. Keep `sliceWarning.reason` as the original diagnostic and continue using the complete transparent spritesheet; a UI may add context when displaying it, but must not rewrite the stored reason.
 - The service contract keeps `warning` and `sliceWarning` mutually exclusive. As defensive handling for a malformed response containing both, treat the general `warning` as authoritative and do not misclassify the source-preserved result as a slicing-only warning.
 
+For reusable transparent game/UI sheets, do not substitute ordinary image generation merely because it can draw several objects in one image. Use icon spritesheet generation when a stable visual-spec reference and `iconDescriptions` exist; use UI extraction only for an existing annotated UI design. Pass `screenColor: "auto"` unless the art direction requires one of the supported solid chroma colors. A client must verify the returned full sheet really contains transparency before treating it as a transparent spritesheet. If a source-preserved `warning` is present, do not register the opaque provider source as the requested transparent deliverable. When only `sliceWarning` is present, the full transparent sheet remains usable, but no individual slices may be claimed.

+## AI Game Creator Canonical Visual DAG
+
+The AI game creator reuses its existing 16-task manifest; do not add a parallel task system or collapse the following artifacts into one ordinary generation request:
+
+1. `art-director` generates `assets/art-spec.png` with `POST /api/external/v1/editor/images/generations`, `kind: "spec"`, and registers it as `assetKind: "icon-spec"`. This is the real visual-spec image. The JSON value in `generationInputs.artSpec` is supporting structured context and does not replace this image.
+2. `design-foundation` uses the registered External Editor resource ID for `assets/art-spec.png` in `referenceImageSrcs`, then generates the complete `assets/ui-prototype.png` through `POST /api/external/v1/editor/images/generations` with `kind: "ui-design"`.
+3. `art-asset-plan` uses the same registered `assets/art-spec.png` resource ID as the required `referenceImageSrc` for `POST /api/external/v1/editor/icon-spritesheets/generations`, supplies concrete `iconDescriptions`, and registers the transparent full result as `assets/art-spritesheet.png`.
+
+Never use `assets/ui-prototype.png` as the icon spritesheet's visual-spec reference. `POST /api/external/v1/editor/ui-designs/assets/extractions` requires an existing UI design image with red-box annotations; it is not UI generation and is not part of this canonical DAG.

 ## Guardrails
 
 - Do not invent endpoints outside the OpenAPI, especially internal worker or runtime task-list routes.

 Before generating art assets, normalize the user's request into a current art spec with `assetType`, `subject`, `style`, `palette`, `composition`, `format`, `constraints`, and `references`. Ask follow-up questions only for missing fields that block the selected endpoint. Reuse the current spec automatically when the user asks for another asset without changing style/spec requirements. Put the spec in `generationInputs.artSpec` and summarize it in the prompt when useful.
 
+For the AI game creator's existing 16-task autonomous build, distinguish that JSON art spec from the required visual-spec image and keep this dependency chain:
+
+1. `art-director` -> `assets/art-spec.png` via `POST /api/external/v1/editor/images/generations`, with `kind=spec` and registered `assetKind=icon-spec`.
+2. `design-foundation` -> `assets/ui-prototype.png` via the same image generation endpoint with `kind=ui-design`, using the registered art-spec resource ID in `referenceImageSrcs`.
+3. `art-asset-plan` -> transparent `assets/art-spritesheet.png` via `POST /api/external/v1/editor/icon-spritesheets/generations`, using the registered art-spec resource ID as `referenceImageSrc` and providing `iconDescriptions`.
+
+Do not use the UI prototype as the spritesheet specification. UI extraction requires a stable source image with red-box annotations and is outside this canonical DAG.

 Infer the endpoint from the user's description. Do not present this as a menu unless the request is genuinely ambiguous.
