Keep synchronous cached CE pixels and hardware headers at stable addresses
outside the fixed Xbox arena, bounded to 128 MiB and 8192 entries. Only
older-frame textures can be evicted; unregister bindings, GPU copies and
channel annotations before freeing, including map/bitmap teardown and flush.
Preserve the original readers, conversion, normal GPU caching and HUD
replacement behavior. Refresh Android GL shadow state before each draw.
Keep the player-tested Android streaming geometry bypass and its regression
tests, since current upstream main does not contain that fix yet. Desktop
and web preserve their cache, upload and draw-state behavior. No fullscreen,
simulation, networking or map-format changes are included.
The engine-owned bitmap getter and teardown require small source hooks,
each marked port:. The renderer admits heap pixels only through a registered
header and validates the resource extent against its allocation. Diagnostics
are limited to unload summaries and the first allocation warning per lifetime.
Device evidence: the tester reports correct rendering and stable FPS, with
zero allocation failures, fallback substitutions or evictions across four CE
visits on Mali-G615 and 87.5 MiB peak residency. Local tests cover stable
uploads, bounds, OOM, frame locks, eviction, cleanup, HUD residency, reduced
diagnostics, normal write tracking, Android-only state refresh and geometry
streaming. All 30 upstream-focused checks passed before final CI validation.
Full Android/web builds require CI because local targets are unavailable.
No fork packaging, branding, map adapters or unrelated changes are included.
Player-Note: Fix Android Custom Edition texture corruption and repeated cache upload hitches.
Player-Note: Prevent stretched or missing geometry on Android by streaming geometry directly.
