The distributable's host-compiled pieces (launcher bin, libapplauncher.so, jlink runtime) are linked against Arch's glibc 2.38/libstdc++ — bookworm has 2.36/3.4.30, so a straight repackage silently exits 1 at launch. dist/bookworm-compat/ holds bookworm-built replacements (launcher-bin, libapplauncher.so, runtime/) extracted once from the known-good 0.1.0-1 deb; make-deb.py injects them into the tar stream without touching the build tree. Verified in a bookworm container: apt install -> ii, zero unresolved libs, app stays up 30s under Xvfb, build 6efec57.
