+## Execution Notes
+
+- Packer runtime output projection is the `assets.pa` asset table generated by
+  `FileSystemPackerWorkspaceService`; `PLN-0088` and `PLN-0089` now project the
+  runtime-effective `palette_count` there.
+- `PackerAssetDetailsService` and `PackerReadMessageMapper` project palette
+  color data through `pipelinePalettes` and do not expose
+  `palette_authored` as runtime-effective metadata.
+- Studio asset details mapping forwards packer details without deriving a
+  runtime count from `palette_authored`.
+- No DTO field was added because doing so would create a new Studio/packer API
+  surface not required by `DEC-0038`.
