PASS - GNU Chess 6.3.0 native UI revisions 6.3.0.8 EN / 6.3.0.9 DE

Current hashes and native test scope: native/native-report.json
Build/engine/memory preservation: ui-engine-and-memory-audit.json
Source rebuild: ../../DEVELOPMENT/source-rebuild-report.json

Both editions rebuild exactly: 13 portable tests and 9 icon/object tests,
including odd/even heap walks. Each edition also passes actual16-bit code
execution with modeled kernel boundaries:24 bounds sets,4295 hit checks,
832 mouse-handler dispatches and26 paint cases, balanced GStates/locks,
unchanged engine arena and keyboard/mouse game/Undo agreement.

Pixel QA passes12 native screenshots at cell sizes24 through79: no invalid
colors, stray piece pixels or empty-square contamination. Original piece
silhouettes and protected pixels are preserved; see pixel-native-summary.json
and pixels-final/ for exact image, source-comparison and cursor-mask scope.

Native: supplied English Ensemble1.2 in emulation; both languages at2MiB
VGA, EN at4MiB SVGA1024x768. Maximize/restore/frame drag/window move, mouse
and keyboard input, depth4, Undo, illegal input, German text, close/reopen,
and old6-to-new8 cache-preserving upgrade pass. No TokenDB deletion.

Independent five-app2MiB pressure loads Write, Draw, Notepad and Calculator
with Chess. All29 swappable engine resources and artwork62 swapped and
reloaded. Resized paint, depth4 reply, pixel-identical Undo and matching
initial/reopened219216-byte/66-handle allocation pass. Idle locks/context
return to zero. Application-owned allocation is zero after close. Dynamic
open UI allocation varies with size/state; shared/font caches are additional.

Static fixed resources plus49152-byte stack: EN128320, DE128336 bytes.
Increase versus preceding slim releases:544 fixed bytes per edition.
All resource reservations plus stack:215552 bytes for either edition.
Native measured fixed: EN128928, DE128944 bytes; oldEN128384.
Arena34336, DGROUP8400, stack49152 and engine/artwork bytes are unchanged.
These reservation figures are not total physical/system RAM consumption.

Historical engine performance/19-million-check evidence is under ../slim
and ../slim-history/COMPARISON for releases6/7. Those timing tests were not
rerun for these UI changes. No exhaustive-position, physical-hardware,
German-system-runtime or all-Ensemble1.x compatibility claim is made.
