The partial-contact imprint (#704, #751) split every face in the contact plane against every tool face, one call per face, and measured all the tool's cylinders for each pair: the sensor enclosure's Case shell went from 6.6 s to 76 s and timed out in the CI matrix. Only faces near the contact are split now, each surface once, in one call: 7.0 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
