Package addrspace reads bytes at runtime virtual addresses for the heap-native pprof label decoder.

Package capture writes the calling process's heap dump to a temp file and returns it positioned at offset 0.

Package heapdump parses the binary format written by runtime/debug.WriteHeapDump (see runtime/heapdump.go) into a normalized heapsnapshot.HeapSnapshot.

Package heaplabels prototypes recovery of runtime/pprof goroutine labels directly from the heap dump's runtime.g objects.

Package heapsnapshot holds the normalized in-memory model produced by parsing a runtime/debug.WriteHeapDump output.

Package memusage implements the core computation behind the /debug/memusage HTTP endpoint: it pairs heap-dump-derived reachability with heap-native pprof label recovery so callers can ask "how much heap is reachable from goroutines carrying these standard runtime/pprof labels?".

Package runtimelayout describes the private Go runtime layout that heap-native pprof label recovery depends on, and resolves it from a small verified table.

Package snapshotgraph turns a parsed heapsnapshot.HeapSnapshot into a compact process-wide object graph with per-goroutine and process-global reachability sets.
