+Saved C2 **orange_round_belt** prior evidence (radius 2.95 mm). **Agent visual and numerical review is complete; owner prior approval remains pending.** The prior is ready for owner review with both inferred hand-hidden arcs and depth/contact uncertainty disclosed below.

+The saved statistical filter used 20 neighbours / 2 sigma and kept **13304 of 13935** eroded points. The run used `waft_stereo_dav2l5`, 2 px erosion, a 400-round budget and reprojection weight **4**.
+
+Appearance initialization contains **13304 observed + 51840 mesh-derived = 65144 seeds**. Vertex colors are observed for 551 mesh vertices and median-filled for 313. Mesh vertices and appearance seeds are not mechanical particles. No post-prior mechanical population or unit-mass total is supplied by this prior run; trained appearance and physical fitting are separate stages.

+**Agent findings.** All 21 initial input, centerline, tube, spatial/depth, residual, color and hybrid images were inspected, together with orbit frames 0, 4, 8, 12, 16, 20, 24, 28 and 32 of 36. These were directly selected frame reads; no full-decode or continuous-playback claim is made. [Exact findings and coverage](<agent_findings.json>).
+
+The visible belt is followed closely in all four camera overlays, with small local contour offsets. Spatial views and the sampled rotation show one smooth, nearly planar oval with slight height variation; no gross wrong-loop displacement, kink or crossing was seen. The orbit displays cross-section rings, so watertightness and intersection results come from the saved numerical checks. **Both hand-hidden arcs remain inferred**, including the substantial foreground-hand/arm and right-side occlusion in camera 12933256. Camera 17736741 retains a small exposed belt patch between the foreground fingers. The 313 median-filled vertex colors lie mainly on the underside and hidden arcs and are not observed texture.
+
+**Vertical placement and table contact remain uncertain.** Minimum tube z is **−2.258 mm** relative to nominal table z=0. Belt-interior-minus-local-table median heights are **9.868 / 5.885 / 8.765 / 5.220 mm** in camera order. The spatial/hybrid plots retain gaps near the hidden arcs, lateral contour bands and depth spread above and around the tube. No depth correction was applied.
+
+Visible-centerline-in-mask fractions are **99.33 / 99.07 / 99.66 / 98.97%**. They are not silhouette IoU. Median point-to-centerline residuals range from **4.824 to 7.024 mm**; all views have small tails beyond 10 mm. Camera 17736741 has the largest median/p90 residuals, **7.024 / 9.083 mm**. These distances include cord radius and measurement/model differences rather than measuring ground-truth reconstruction error.
+
+The length is **638.708 mm**, **3.708 mm** above the lower soft bound; the saved within-1-mm flag is **false**. One fit round stopped at the configured gradient tolerance. Maximum curvature is **19.332/m**, and **48.8%** of samples exceed the soft **10/m** curvature threshold. These soft-loss diagnostics do not establish global optimality. No blocking issue for presenting this saved prior to the owner was identified.
+
+Owner prior approval remains pending. No prior payload, source settings, case status, owner acceptance or downstream approval was changed. The completed temporal-reference review was not rerun; mechanical populations, trained appearance and physical fitting remain separate.
+
+## Owner decision, 2026-10-28
+
+“Approve 231046’s prior”. Accept this reviewed orange-belt prior for mechanical input preparation and reference static appearance training, retaining hidden-arc and table-contact limitations. Trained appearance acceptance and physical fitting remain separate.
