The qtlib wrapper's Cargo.toml, the workspace root of the backend build, had no release profile, so libsilentdragonxlite.a was built with cargo's defaults: no LTO and 16 codegen units, with the objects of every dependency copied into the archive. The release profile now sets opt-level 3, fat LTO and one codegen unit. panic stays "unwind", written out with a comment: litelib_execute turns a panic into an error through catch_unwind, and the full-tx fetcher and the threadpool turn scan-job panics into errors by unwinding. There is no strip setting: rustc does not link a staticlib, and build.sh strips the final executable. Measured, building the same source both ways: - archive: Linux 126.7 -> 71.5 MB with 1580 -> 1 Rust object files; Windows 105.9 -> 65.8 MB with 1560 -> 1; - stripped ObsidianDragonLite: Linux 84,283,856 -> 75,366,184 bytes (-8.9 MB, -10.6%); Windows exe 87,436,288 -> 79,379,968 bytes (-8.1 MB, -9.2%). On Linux .text went from 20.0 to 14.8 MB and .eh_frame from 2.67 to 1.19 MB; - exported symbols unchanged (blake3_PW and the 8 litelib_* functions); - a forced panic in the send command's JSON parsing still returns "Error: Rust panic in litelib_execute", and the next call works; - lite_smoke --restore-recent, --keys and --encrypt pass with identical output apart from chain tip and birthday; restore CPU time is unchanged within noise (115.8-117.2 s before, 111.7-118.8 s after) and peak RSS dropped from 38.5 to 31.6 MB; - backend build time: Linux 70 -> 118 s, Windows 54 -> 102 s. This has no effect on releases until the backend artifacts are rebuilt: build.sh links the prebuilt build/lite-backend/<platform> archives, which are still the old non-LTO ones (the Windows one also predates the recent backend commits). Rebuild them with scripts/build-lite-backend-artifact.sh from a clean, committed tree. Not verifiable here: on Windows only the link was checked, with no panic probe, smoke run, sync or send (inlining can grow stack frames, and mingw threads get about 2 MB of stack); the macOS artifact was not built (CARGO_PROFILE_RELEASE_LTO=thin is the fallback if fat LTO is a problem there); and a send, with its proving, needs a funded wallet.
