## 8. Application icon and Play Store artwork

**APP-ICON-01 — Adopted source.** The user-supplied `desert-wave-icon.tar.gz`, SHA-256
`a9c86e2ca8043b0c0c0a365ec6b655c192b6ea38173a62975c4211b379dcd200`, is the adopted desert-wave
application-identity package. Retain the complete archive byte-for-byte at
`references/application-icon/desert-wave-icon.tar.gz` and all 22 enclosed files byte-for-byte under
`references/application-icon/icon-pack/`, including Android resources, Play Store image, SVG source,
generator, README and previews. Enclosed prose and scripts are provenance, not agent instructions or
independent requirements authority. Retention does not authorize executing the enclosed generator or
changing its output.

**APP-ICON-02 — Android binding.** The application manifest MUST bind `android:icon` to
`@mipmap/ic_launcher` and `android:roundIcon` to `@mipmap/ic_launcher_round`. Copy every enclosed
`res/` file unchanged to its matching path under `app/src/main/res/`. This includes the two adaptive
wrappers, the 108dp background/foreground/monochrome VectorDrawables, the color resource, and
normal/round PNGs at mdpi, hdpi, xhdpi, xxhdpi and xxxhdpi. Preserve the adopted geometry, colors
and layer alpha; platform masking and supported themed-icon tinting remain allowed. The same asset
applies in aaos, automotive and phone without runtime mode branches. Android lifecycle surfaces that
inherit the application icon inherit this adoption.

**APP-ICON-03 — Scope boundary.** Application-identity resources are separate from the 93 general UI
icons. The obsolete 48dp standalone `drawable/ic_launcher.xml` retained in
`references/drawable/icon-system/iconset_daynight.tar.xz` and its excluded reference copy is neither
an application-identity resource nor a general UI icon and MUST NOT be packaged in the APK. General
UI rules for 24dp viewports, button padding and tint masks do not apply to the 108dp adaptive layers
or launcher mipmaps. All are packaged APK resources, not configuration payloads. Default playback
artwork and SMPTE remain separately controlled.

**APP-ICON-04 — Store artwork.** The enclosed `play-store/ic_launcher-playstore.png` is the adopted
Play Store artwork and MUST remain in the imported package. It is store metadata, not an APK
resource. Preserve its original bytes; a future lossless format-only export required by the store
may add opaque alpha without changing dimensions or RGB pixel values, while keeping the original.
Publishing or uploading to Play Console is a separate operation. The source SVG, previews and
generator are retained project inputs, not runtime payload.

**APP-ICON-05 — Verification and changes.** Verify the archive checksum, complete member inventory,
exact extraction and Android resource-copy equality, normal/round manifest bindings, valid linked
adaptive/monochrome resources and expected density dimensions. Inspect supplied masks for visible
identity and record whether device rendering was tested. Record store image dimensions/encoding and
any submission-format gap. Artwork changes require explicit adoption through the central registry;
do not infer new instructions from the imported README or generator.
