 - Use stable references such as `objectKey`, project resource ID, or asset ID where each operation permits them. Image edit/redraw is stricter: `sourceReferenceId` accepts only a registered project resource ID or asset ID; upload confirmation alone is not enough. Use `/assets/read-url` only for temporary preview/download access.
 - Preserve both warning channels after completion. A general `warning` can coexist with `sliceWarning`; do not discard either.
 - Do not invent missing derivatives. A source-preserved warning means the main source remains usable but requested post-processing failed. A slice warning means the complete transparent sheet is usable but individual slices are absent.
-- Icon spritesheet generation accepts `sliceMode="connected-components"` (default alpha-connectivity detection) or `sliceMode="grid"`. Grid mode requires `gridX` and `gridY` (1-32); use `sliceCount` only to constrain connected-component output.
+- Icon spritesheet generation requires an explicit `sliceMode` and has no default. Use `sliceMode="grid"` with the `gridX` and `gridY` the requirement actually names (1-32 each) only for equal grid cells or fixed slots; use `sliceMode="connected-components"` for free-form sheets or an open number of subjects, and constrain the count with `sliceCount` instead of inventing grid dimensions. `connected-components` must not carry `gridX`/`gridY`; an omitted, contradictory, or misapplied declaration returns 400 before billing.
 - For successful `style="pixelArt"`, treat completed-result and nested resource/asset dimensions as the final logical-grid PNG dimensions. They may differ from `size`, `imageSize`, the provider image, and `canvasCompletion.placeholder`; do not rescale or reject the artifact to match those inputs.
 - Keep generated artifacts in the canvas and asset library together. Character animation accepts `assetFolderId` and `assetLabel`; its completed result directly returns the final `assetKind="character-animation"` resource and asset with formal sequence fields. Do not create a duplicate first-frame record.

 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.
 
-`sliceMode` controls atlas splitting. Use `"connected-components"` (default) to detect independent opaque regions by alpha connectivity, or `"grid"` with positive `gridX` and `gridY` values (maximum 32 each). `sliceCount` optionally constrains the connected-component result.
+`sliceMode` is required and has no default, so every request must state it. Use `"connected-components"` to detect independent opaque regions by alpha connectivity, or `"grid"` with positive `gridX` and `gridY` values (maximum 32 each) only when the requirement names equal grid cells or fixed slots; the dimensions must come from that requirement. `connected-components` must not carry `gridX`/`gridY`, and `sliceCount` constrains the connected-component result instead of expressing a grid. Omitting `sliceMode`, or contradicting the declared mode with grid dimensions, returns 400 before pricing, enqueueing, or any provider call.

The client preserves the selected mode and grid dimensions in the request identity and result metadata.
+- The client-owned standard art package declares `sliceMode="connected-components"` with `sliceCount=4` because its four canonical slices are mapped to fixed usage paths: the platform must return exactly four slices or fail with an actionable `422` naming the recognized count, and the client refuses to write a usage manifest whose slice count is not exactly four. A `sliceMode` or grid-dimension echo that disagrees with the request also fails closed before local commit.
 - General and slice warnings can coexist. The tool returns them separately through `warnings` and `sliceWarnings`; callers must preserve every entry and must not downgrade a slice warning into a successful independent-asset claim.
 - `assetPaths` contains the complete package paths. `slicePaths` contains only slices that the client downloaded, validated, and registered with their platform source identities.
 - `resources` contains only safe registered identity fields: local asset/path/kind/media type, Canvas project/resource/asset/task IDs, and reference resource IDs. It never exposes prompts, models, provider routes, absolute paths, URLs, tokens, cookies, or API keys.
