• Platform-defined targets, fewer hard-coded OS/arch facts: 12 engine gaps + 3 bugs measured while porting a C program (cmd) to ok images, FreeBSD and i386 with mcpp only

• Shared images are DF_STATIC_TLS on GCC (static libstdc++'s call_once uses initial-exec TLS): dlopen fails once dependencies hold more than a few KB of TLS

• GCC 16 modules: an importer of an inline body that reaches mcpplibs.os fails ("Bad file data" / unresolved optional<vector<grant>>)

• fix: emit sbom states the lock's spelling of a package, so one package has several purls

• fix: emit sbom and --locked read a missing mcpp.lock as an empty one, so neither says it is missing

• A workspace's target/ is 25 GB for one configuration (bin/ is 14× obj/: test binaries, member archives and staged .so copy the closure; nothing collects generated or nested build-program trees), and mcpp test --workspace recompiles most of the graph once per member
