For an icon-spritesheet primary spec, additionally create a project resource or asset record with `assetKind="icon-spec"`, then pass the returned resource or asset ID as `referenceId`.
 6. For generation endpoints that support the fields, include `projectId`, `assetFolderId`, an asset label, and `canvasCompletion` so the result enters both the canvas and its same-name library folder.
 7. Treat every generation POST as asynchronous. Send one stable `Idempotency-Key` per logical request, retain the returned `operationId`, and poll the returned `statusUrl` or `GET /api/external/v1/generations/{operationId}` according to `pollAfterMs`.
 8. Consume `result` only after `status=completed`. On `failed`, surface the safe error. On a client timeout or lost response, retain the operation/key; do not create a replacement request.

+The icon-spritesheet primary `referenceId` is intentionally stricter than ordinary image references: it accepts only a current-owner project resource ID or asset ID whose authoritative `assetKind` is `icon-spec`. It does not accept an `objectKey`, URL, Data URL, or Blob URL.

 For a playable Canvas game, do not stop at generation. Make `code-prototype` depend on `art-asset-plan` and consume the persisted `iconImageSrcs` slices for core players, blocks or targets, scene obstacles, and feedback. For the four-category game-chat contract, require exactly four slices before registering the local runtime sheet; both fewer and extra components fail closed. Treat `art-spec.png` as reference-only. A full-sheet `<img>`, CSS background, path-only mention, guessed equal-grid crop, or code-drawn replacement for core entities is not runtime asset use. If slicing produces `sliceWarning`, keep the complete transparent sheet as a valid editor artifact, but fail the playable game asset gate until real slice files or verified atlas coordinates exist; never invent coordinates or replace the icon-spritesheet route with ordinary image generation.
