+
+Saved C2 **orange_round_belt** prior evidence (radius 2.95 mm). **Agent numerical/visual review is complete; owner prior approval remains pending.** The projected geometry follows the exposed belt in all four views without a gross mismatch. Both hand-hidden arcs and the underside remain inferred. This packet is ready for owner review with the recorded depth and contact limitations; it records no acceptance.
+
+Initial reference frames are the saved nearest-camera observations of the first 30 Hz sample. The local row, converted frame, native-container frame and capture clock remain distinct in [the metrics JSON](<prior_metrics.json>).

+The saved statistical filter used 20 neighbours / 2 sigma and kept **13302 of 13938** eroded points. The run used `waft_stereo_dav2l5`, 2 px erosion, a 400-round budget and reprojection weight **4**.
+
+Appearance initialization contains **13302 observed + 51840 mesh-derived = 65142 seeds**. Vertex colors are observed for 541 mesh vertices and median-filled for 323. 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.

+Camera 12540311 has upper and lower foreground hidden arcs; 12933256 has a broad lower foreground-arm arc plus the upper-right grip; 17736741 has upper and lower-left gaps; 23007103 has upper-left and lower-right gaps. The combined cloud is sparse or absent near both ends of the elongated loop.
+
+**Depth and contact limitation:** The depth cloud is spread above the fitted tube and has lateral bands, particularly along the right side in the top view. Camera 23007103 has the largest median/p90 centerline residuals, 7.826/9.963 mm. Histograms for cameras 12540311, 17736741 and 23007103 have tails beyond 10 mm. Minimum tube z is -1.259323 mm relative to the nominal z=0 table plane. Belt-interior-minus-local-table medians are 9.781, 4.525, 6.684 and 5.700 mm in listed camera order. Camera-dependent offsets and depth spread leave vertical placement and table contact uncertain; no correction was applied.
+
+The spatial views and sampled orbit show a coherent, nearly planar oval with no gross crossing, detached component or sharp kink. One optimization round stopped at the configured gradient tolerance. Maximum curvature is 18.449/m and 44.4 percent of evaluated samples exceed the soft 10/m regularization threshold. That threshold is not a hard geometry acceptance test, and this review does not establish global optimality. The saved length is 638.305 mm within the 635-660 mm soft bounds, 3.305 mm above the lower bound; the within-1-mm bound flag is false. Full-loop shape and length remain model estimates where hand-hidden arcs lack observations.
+
+Both hand-hidden arcs and the underside remain inferred geometry. Projecting the prior across the hands does not reveal the hidden belt shape or verify physical contact. Sparse initial support does not independently determine those missing arcs. Median-filled colors on the underside and hidden arcs are initialization values, not observed texture.
+
+[Agent findings and exact review coverage](<agent_findings.json>) record all four initial native input panels, four centerline overlays, four masked and four unmasked tube overlays, the five spatial/residual/depth/color/hybrid plots, and orbit frames **0, 4, 8, 12, 16, 20, 24, 28, 32** of 36. The orbit displays sampled rings/vertices; saved numerical checks provide the topology evidence. The prior payload was read only and the temporal-reference review was not repeated.
+
+Owner prior approval remains pending. No case status, prior acceptance, mechanics approval or trained-appearance approval is changed here.
+
+## Owner decision, 2026-10-28
+
+“Approve 230830’s prior”. Accept this reviewed orange-belt prior for mechanical input preparation and reference static appearance training. Trained appearance acceptance and physical fitting remain separate.
