Headless Linux benchmark/hash tool (Clang 19 / GCC 14) sharing the viewer's plan builder and streaming pipeline (moved verbatim into StreamBenchmarkPipeline.h / WorldAssemblyPrototype.h). Owner Round17 view: density/mesh/payload/topology hashes equal the Windows S13 reference at W1/W8/W12 (Clang, 3 runs each) and W8 (GCC), with -ffp-contract=off. No output change. Baseline (i9-12900H, CPUs 0-11, powersave/balance_performance): whole view W8 3.562 s median, W12 3.512 s, W1 16.555 s; peak RSS < 605 MiB. Review: the default-stack crash is 17.3 MiB of static TLS per thread (glibc puts it in the thread stack; HeightfieldColumnCache 6.8 MB), not recursion -- open, after S14. MSVC compile of the viewer refactor not verified (no MSVC here). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
