Baseline had panic=abort only. Measured each setting in order (docs/RUST.md's new "APK size (2026-09-07)" subsection has the full table and crate breakdown): strip=true, lto="fat", codegen-units=1, opt-level="s" take libmain.so from 18,546,488 to 11,193,608 bytes (-39.7%) and the release APK from 20,678,956 to 13,326,076 bytes (-35.5%), arm64-v8a. opt-level="z" was measured (another ~800KB) but not adopted without a frame-time check. Investigated naga/wgpu backend features and tabs-ui/tabs-screen as trim candidates; both are already fully eliminated by the linker on Android (0 symbols in `llvm-nm` on the baseline .so), so no Cargo feature change would shrink the binary -- left as documented findings rather than a diff. Embedded Noto Sans fonts (3.6 MB) and the wgpu/naga/font-shaping stack account for most of what remains vs. Compose, which borrows the platform's own renderer and fonts for free; recorded honestly in the doc rather than trimmed, since subsetting fonts or dropping a backend would change what iris can render.
