"""EXP-3D-RGBD-DEPTHSPLAT-JEPA-OVERLAP-SCALE-ARKIT-V1: scoring and the preregistered analysis on the VAL80 part of ARKIT160_OVERLAP (source_cohort ARKIT_VAL; queries = frames 6 and 7, or the next free frame where a record uses one). score: every prediction must be sealed and unchanged before query depth is read: the reused OVERLAP-V1 arms seal (REPROJ_HARMONIC = H3, NEAR, G1 depth and opacity, three seeds) and JO1-JO3 CTX seals (hashes in reused_seals.json), and this experiment's JOL1-JOL3 CTX seals (cap 3.0, each naming its trained checkpoint's hash). Per query (as OVERLAP-V1): JO, JOL where at least two of the three seeds cover the pixel (alpha >= 0.5): the mean ray depth (depth_z / alpha / cos) of the covering seeds; elsewhere H3 G1N per G1 seed depth / opacity where opacity >= 0.5, else H3, mean over seeds Regions: FARH = FAR (valid pixels outside the 8-px NEAR of the context reprojection) of the queries with at least one context hit; FAR of every query; NEAR. Only VAL80 scenes are scored (the CONFIRM80 scans are JOL training data). Scene value = mean over roles of the mean over queries (empty regions skipped). analyze: V1's paired scene bootstrap (10,000 draws, seed 20260928) and V2 gate.
