Arctic finite ground: domain and blend qualification

The exact 1536x1024 opaque native arctic ground retains crisp snow strokes, unequal rock shelves and a broad asymmetric exposed-ice area without its parent focal crater. Independent PNG and Sharp decodes agree on all1,572,864opaque pixels. Its inherited metadata blend polygon contains426,632native pixel centers(27.12%);1,146,232lie outside. This is prospective declaration geometry,not an actual live crop,feathered screen coverage or subject-preservation result. A fresh read-only canonical engine check found27unoccupied arctic cells for the full proposed rectangle at a naturally selected existing magic foreground. Neither this ground nor its preserved parent has a local/production source contract. Resolve the finite terrain domain and inherited blend coverage in normal desktop/phone Region/Hex context before any artwork or admission decision. Three retired historical review links remain explicitly historical. No normal world frame,approval or live appearance is claimed.

The native study and original Celestial Crater companion remain unchanged. The exposed ice is part of an opaque terrain composition; it is not being judged as a freestanding transparent object. The inherited polygon is only a metadata declaration, and there is no candidate runtime contract. Its point coverage therefore identifies a question for actual rendering rather than proving an active clipping defect. The preserved image remains the preferred study until a source-bound comparison demonstrates a better result.

The eligible disposable-world location uses the existing magic-arctic-triptych foreground and native snow floor, not a fabricated Celestial Crater site. No geography, hydrology, feature, ownership, resource or save is changed. The next capture must recheck the connected engine before drawing. It must compare a complete unique composition and any proposed terrain-domain blend, inspect the actual foreground, and keep full physical grain, state/lifecycle, GPU/fallback and performance gates open. No pattern may repeat this scene.

The old three review paths are retained as historical provenance in metadata. Current native bytes, the prior exact-source review facet and the new read-only findings supply current evidence; retired planning artifacts are not recreated.
