naksheap: reconstruct heap object graphs from core dumps 
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/

Generated artifacts, not hand-edited sources.

File Contents
toy-server.core A deterministic synthetic ELF64 core dump
toy-server.core.manifest.json The ground-truth manifest for that core: arenas, objects, roots, edges

Regenerate from the repo root:

cargo run -p naksheap-testkit --example gen_fixture -- fixtures

The build is byte-for-byte deterministic. This golden core guards against regressions in the parser, carver, and scanner.
