Original-RGB finite ruined-wall study

The preferred study separates the low ruined enclosure in WOG-A-001710 from its repeating diagonal outer terrain. It retains the original 1254 by 1254 canvas, every one of the original 1,572,516 RGB samples, the complete curved and straight broken walls, central rubble, detached lower-right wall, loose stones, moss and site plants. Only alpha changes; the original painting and WOG-A-005349 historical lossy comparison remain intact. The archive's accepted comparison disposition and existing goal action are preserved.

The built-in image_gen tool supplied an aligned transparent extraction proposal. Its generated RGB is discarded. The selected native PNG copies the original RGB samples exactly, uses the generated alpha with a bounded edge cleanup, and protects an authored 192,482-pixel ruin region at full opacity. No source or mask resizing, crop, rotation, mirroring, sharpening or lossy recompression occurs. The original colour chunks are retained; the original provenance container stays in the untouched original instead of being copied into a modified asset. Exact prompt and generation record generation.json.

Independent PNG and Sharp decodes prove zero changed RGB pixels across the entire native image. Ordinary HTMLImageElement/Canvas decoding preserves every opaque RGB pixel and every protected-region RGBA pixel exactly. The candidate has 1,282,697 transparent pixels, 8,888 partial-alpha pixels, 280,931 opaque pixels and zero visible image-border pixels. The partial fringe has 6,339 browser RGB readback differences, maximum channel difference 14; these remain explicit rather than being hidden by a tolerance. Native proof native-matte.json, browser proof browser-native-proof.json.

The complete native source, full alpha composite and side-by-side native crops were visually inspected. Masonry detail, the curved inner section, upper-right broken wall, detached lower-right wall and associated loose rubble remain recognizable and complete. Shared world ground is intended to supply the background while this finite site is drawn once. Its irregular soil/contact fringe still needs actual terrain matching, edge and shadow review. Parent mountain, hills and grasslands intentions are proposed context scope, with no inherited canonical scale, anchor, source permission or gameplay behavior.

WOG-A-009285 is a preferred study with no full artwork approval or source admission. Normal desktop/phone Region/Hex role, scale, contact, neighboring/UI composition, state, lifecycle, performance and actual production-world appearance remain pending. The static native browser proof contributes zero normal world frames. No functioning keep, garrison, ownership, defensive action or new player interaction is created.

Keep the original and the selected native study. Retire the unselected generated RGB/alpha-input file and the single temporary full-alpha preview only after final preservation and Atlas checks. Retain the compact proofs and one decisive native crop comparison native-comparison.png. The active 90-contract canonical run and the preceding lifecycle release remain separate.
