Add rational atlas cells and bounded authenticated Original-detail retention with standalone synthetic regression checks. Rebuild Linux and Windows runtimes; validate all 5384 supplied frames and preserve three exact 1080p regression controls.
Accept strict common-scale integer rounding for complete transparent PNG canvases while retaining source-aware alpha checks and existing opaque/exact cache identities. Add separate cache identity for newly eligible rounded transparent frames and matching Rust/Python regression coverage. Bundle rebuilt Linux and GNU Windows executables against the unchanged reviewed4978 asset pack.
Validation: 31 Rust HD tests, 7 Python audit tests, and 341 portable tests passed; zero failures. Original-data integration validated all4978 remasters at scales1–4 with bounded caches. Three fresh software SDL1920x1080 menu/mission captures are pixel-identical to published controls. Windows PE/dependency and complete shared data hashes verified; fresh Wine asset and45-mod validation passed. Artwork geometry remains independently reviewed; no held candidate is admitted by the format change.
