Original-RGB finite keep service-lodge study
The small walled lodge in WOG-A-001697 has a separate finite transparency study,WOG-A-009286. Every native RGB pixel remains unchanged,including pixels hidden under alpha0;the complete original and its historical WOG-A-005348 comparison remain intact. The original1254by1254canvas,projection,palette,roof and facade detail are preserved without source or mask resampling. The wide repeated outer grass field and detached rocky rise are removed from the visible domain;the complete enclosing wall,gate,courtyard and narrow irregular contact fringe stay visible. This candidate is drawn once,never used as repeating mesh ground.
The built-in image_gen tool supplied only an aligned alpha guide;none of its generated RGB is used. An authored20863pixel lodge core is forced opaque to preserve the full native subject. Independent PNG and Sharp decoders prove all1572516RGBpixels exact. Normal HTMLImageElement/Canvas decoding preserves every opaque RGB sample and protected-region RGBA sample. There are1477partial-alpha pixels,of which1065have RGB readback differences with maximum channel difference14;these remain explicit. No visible image border pixel survives. Exact prompt generation.json,native proof native-matte.json,browser proof browser-native-proof.json.
The full original and the complete visible finite output inside the native comparison crop were personally inspected. The fine roof,masonry,gate,wall and courtyard details remain recognizable. Its small native subject cannot be enlarged through a performance shortcut;canonical size and terrain contact require normal desktop/phone Region/Hex verification. Parent mountain,hills and grasslands intentions are proposed scope only. Neighbor/UI,edge/shadow,state,lifecycle,memory/performance,source admission and actual world appearance remain pending. No functioning guardhouse,garrison,stock,ownership,defense or new player interaction is implied. Static native browser proofs contribute zero normal world frames and no full game-ready approval.
Keep every original and the selected native study plus the decisive native comparison native-comparison.png. Retire the raw generated alpha input only after final preservation and Atlas checks. The existing ninety-contract run and preceding ruined-wall release remain separate.
