host/chez/build-joltc.ss builds joltc into target/<profile>/joltc: it emits a flat source of the full runtime + compiler image + inlined build.ss + every jolt-core/stdlib file as a baked string literal + a cli.ss-style launcher, then (in a fresh Chez, so the inlined runtime's redefinition of error doesn't strand early references and runtime eval still sees the runtime's top-level procedures) compiles it and cc-links it with the Chez petite/scheme boots and the launcher stub embedded as C arrays. The launcher reads those arrays via FFI on (jolt-materialize-bundles!) and registers them so build-self-contained can spill them. joltc itself is cc-linked (clean signature for Homebrew); only the apps it later builds use the appended-stub path. build.ss: skip the csv toolchain check on the self-contained path and create the build dir with a subprocess-free bld-mkdir-p, so a from the distributed binary shells out to nothing. release = optimize-level 3 + no inspector info + compressed; debug = optimize-level 0 + inspector + procedure source + debug-on-exception. joltc-selfbuild-smoke.sh (make joltcsmoke) builds joltc and, with an empty environment (no chez/cc/PATH), drives it through the build-app fixture, asserting the produced binary's output. .gitignore ignores target/.
