Rust workspace that turns a core dump of a stripped, optimized C/C++ binary into a typed heap object graph: objects, sizes, allocator state, references, and probable struct layouts, all without debug info. - glibc ptmalloc carving (main + thread arenas, tcache/fastbin freed state, mmap allocations), ELF core + memory-list minidump parsing - pointer scan, layout clustering, vtable/string/vector detection, confidence + evidence on every node - ASCII/JSON/Graphviz/HTML output, synthetic fixtures with ground truth, and real-dump validation harness (aarch64 glibc 2.39) in scripts/ - web deployment reference stack in deploy/ MIT OR Apache-2.0
