Native ruin matte and actual Region contribution

The preferred native ruin matte removes the surrounding repeated tundra without repainting the structure. Every original native RGB value across1572516pixels remains exact at1254x1254;only alpha changes. Native light/dark inspection retains the complete slate roof,masonry damage,front wall,pole,blue flag and courtyard/rubble detail,without the first trial's geometric collar. A generated transparency guide supplies the outline;all generated RGB is discarded. Conservative interior-opacity restoration and recovery of the original blue cloth silhouette avoid a translucent structure and brown background extension from a longer generated flag. The final native alpha covers118676opaque and22527partial pixels,with1431313fully transparent pixels and no visible image-edge contact. The irregular immediate ground contact still needs actual matching tundra inspection;no normal family/ruin-state contract,physical scale,neighbor occlusion,lifecycle,performance,source admission or production appearance is approved. A full alpha-component audit then removes 1558 disconnected alpha-1-only background pixels before publication;all 141129 connected ruin/contact pixels remain unchanged. Actual visible-domain bounds are [314,412,915,832].

Four normal Region control/candidate cases directly measure the selected glyph contribution in actual composited map pixels. Omitting only its normal paint call changes11848and11840desktop pixels,and11946and11939phone pixels. No pixels outside the complete transformed source rectangle change,and restoring the call reproduces the entire map exactly in all four cases. Initial snapshots also match the settled baselines;four normal pan/reconnect maps remain exact. This is positive visible contribution evidence rather than source-cache availability or a paint-call count. It covers this one unchanged arctic magic site and these private cohorts. The earlier missing desktop glyph capture is retained;its cause,broader startup recurrence and full combined memory/performance acceptance remain unresolved.

Original artwork,earlier failed witnesses and every readiness gate remain preserved. No source admission or public renderer change.
