An open, modular, inspectable perception pipeline that composes MiDaS / DAV2 (depth), YOLO (detection), MediaPipe (hands), MOG2 (background) under geometric glue — per-frame optical-flow pose chain, two-bone analytic IK, COLMAP sparse-cloud reuse for gsplat initialisation. We measure the pipeline across three regimes: novel-view synthesis against COLMAP, pose quality against ground truth on five TUM fr3 dynamic sequences, and detector-generation modularity. We report both wins and catastrophic failures honestly, and scope ORB-SLAM3 / DROID-SLAM / MASt3R-SLAM baselines as the explicit next experiment.

Controlled measurement of what a Layer-3 affordance descriptor extracted from one 5-second human-video clip adds over a no-demo hand-coded planner, under matched scaffolding across five MuJoCo Franka Panda tasks. Three default-sufficient control tasks (T1–T3): the demo adds nothing measurable. Two structural tasks: T4 (top-knob mug) exits the default regime; T5 (articulated-arc knob turn) is the paper's one clear positive demo-vs-default result (paired-McNemar p = 0.0026 strict / p = 3.6 × 10⁻⁵ relaxed). A short HOT3D fine-tune of DAV2 Metric brings Layer-1 wrist RMSE from 128.81 cm out-of-box to 13.71 cm pooled on held-out clips — a 4-9× in-distribution reduction.
