Tool: MeshLab 2025.07 (macOS arm64)
Result: BLOCKED FOR UNATTENDED DECIMATION
Input attempted: original.obj (32,269 triangles)
Outcome: The installed 2025.07 macOS package contains only the GUI binary. `meshlab -h` advertises mesh/project opening only; the historical `meshlabserver` batch executable is absent. The source model opened successfully in the GUI, but no noninteractive filter runner is shipped, so an unattended repeatable quadric-collapse output was not produced. PyMeshLab was intentionally not substituted because this ForgeApps environment prohibits Python tooling.
Evidence: /Users/forgebot/tmp/pedal-tool-hypothesis-study/tools/meshlab-help.log and installed application inspection.
