-Saved C2 **grey_timing_belt** prior evidence (width 25.00 mm, zero-thickness surface). The owner accepted this prior on 2026-10-29. The numerical packet below reports saved values. A bounded agent visual review is recorded in [agent findings](agent_findings.json); it found no gross mismatch in the inspected four-camera initial overlays and sampled rotation, and records no owner 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 **44603 of 45856** eroded points. The run used `waft_stereo_dav2l5`, 2 px erosion, a 400-round budget and reprojection weight **4**.
-
-Appearance initialization contains **44603 observed + 21600 mesh-derived = 66203 seeds**. Vertex colors are observed for 426 mesh vertices and median-filled for 24. 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.

-Bounded visual review is complete in [agent findings](agent_findings.json), with inspected images and quarter-orbit samples listed explicitly. The main limitations are the 0.732 mm soft-length-bound excess, larger 23007103 depth residuals, a −2.884 mm minimum geometry height in the table frame, and sampled rather than frame-by-frame video inspection. The residual-histogram axis uses a generic centerline label; these timing-prior values measure ribbon-surface distance. The owner accepted this prior on 2026-10-29. No case status, prior acceptance, mechanics approval or trained-appearance approval is changed here.
-
-## Owner judgment
-
-The owner accepted this reviewed prior with “I approve for both” on 2026-10-29. [Exact accepted artifact](../../../owner_prior_acceptance_c6a_v1.json). The limitations above remain; mechanical/static-appearance preparation is authorized. No trained appearance or physical fit is accepted by this decision.
