The linux-arm64 AppImage, the SBC PortMaster zip and the RG34XXSP zip shipped LuaJIT 2.1.0-beta3 (2017): Debian bullseye's libluajit-5.1-dev for the AppImage, PortMaster's love_11.5 runtime library for the zips. With the JIT enabled, beta3 segfaulted 3/3 runs on a TrimUI Brick; LuaJIT v2.1 commit c6ffc141 ran a 26-minute JIT-on soak without a crash. - Build LuaJIT c6ffc141 from a sha256-pinned tarball in a digest-pinned debian:bullseye (glibc 2.31) with the same apt sources as the AppImage builder; compile with PREFIX=/usr so no build path is baked into package.path, stage-install, and verify before use. - AppImage: compile it inside the builder instead of libluajit-5.1-dev, bundle it with jit/*.lua and its license; cache keys include the LuaJIT commit, recipe hash and Dockerfile hash. - PortMaster zips: replace libs.aarch64/libluajit-5.1.so.2 with the pinned build, pin the PortMaster runtime to commit 715f50fd with sha256 checks (rg34xxsp followed main), ship LuaJIT-COPYRIGHT, verify the finished zip. - verify_luajit.sh gates every package: version string, not beta, aarch64 ELF, /usr module path, max GLIBC <= 2.31; offline selftests cover it and the PortMaster helpers. - CI/release build LuaJIT once on an arm64 runner and pass it to the zip jobs via GEN1RECOMP_LUAJIT_LIB. The JIT stays off by default (LÖVE's jitsetup disables it on arm/arm64). POKEPORT_JIT=1 needs stability testing on H700, RK3566 and A133P devices before it can be enabled by default.
