Summary

  • add a research-only OpenUSD LOD payload composition probe
  • record authored payload arcs, LoadNone, selective loading, and LoadAll point counts
  • harden relative output paths and cover them in the CTest harness

Review fixes

  • normalize relative output paths before payload authoring
  • report the measured LoadNone loaded-LOD count instead of a literal value

Validation

  • ctest --test-dir build/cy2026-windows-x86_64-py313-usd -C Release -R '^usdPointCloudAuthoring_runtime_lod_payload_probe$' --output-on-failure
  • ctest --test-dir build/cy2026-windows-x86_64-py313-usd -C Release -R '^(usdPointCloudAuthoring_unit|usdCopc_runtime_streaming_probe)$' --output-on-failure
  • git diff --check

The probe remains research-only and does not claim host LOD decisions, renderer loading, or renderer memory savings.
