FR-PLAT-AND-5. Android asks for memory back through onTrimMemory and kills the process if it is not given; until now nothing listened, so the answer was always "no". A tiered registry answers instead: GPU caches first, then proxies, then thumbnails, driven from android_main on MainEvent::LowMemory and MainEvent::Stop. The order is the argument. A backgrounded app has no window to draw and therefore no use for a render pipeline, while its thumbnails are exactly what the user will be looking at half a second after they come back -- so going into the background frees only the GPU tier, and only being measured against death frees everything. Sinks register beside the cache they free and hold weak handles, so the registry cannot keep a controller -- and every decoded portrait in it -- alive past the interface it belonged to. `try_borrow_mut` and skip: a warning can land mid-render, freeing textures under the code drawing with them is worse than missing one, and a warning not acted on is always followed by another. The GPU test is the one that matters: an eviction must change no pixel. A freed intermediate pool whose `colour_key` promise still stands renders an empty texture, and nothing else would have caught it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
