  "limitations": "Accounting microbenchmark. Same signed fixtures and correlated issuer; many allocations reference the same descriptor. Heap delta includes ledger-owned policy/path and excludes prebuilt inputs/caller receipts; requested bytes, not allocator metadata or RSS. Timings single-run with filesystem sync, not throughput or production latency."
