"""EXP-3D-RGBD-ENSEMBLES-ARKIT-V1: scoring and the preregistered analysis of both ensembles on ARKit (real sensors). score: every prediction must be sealed and unchanged — the arms seal (REPROJ_HARMONIC, NEAR, G1 for three seeds), the geometry seal (REPROJ7_HARMONIC, NEAR7, ray cosine; replayed against the arms seal) and the DepthSplat seals (J1-J3: CTX; ZS: CACHE, TTT_m1); only then is query depth read. Completion ensemble (three context frames; FAR = valid pixels outside the 8-px NEAR of the context reprojection): H3 REPROJ_HARMONIC; G1 mean of three seeds; J where >= 2 of the 3 J seeds cover (alpha >= 0.5) the mean ray depth of the covering seeds, else H3; JG covered (J + G1) / 2 else G1; HG (H3 + G1) / 2; HJ covered (H3 + J) / 2 else H3; HJG covered (H3 + J + G1) / 3 else (H3 + G1) / 2. ALL versions use H3 in NEAR. TTT ensemble (context + four stream frames): R7 REPROJ7_HARMONIC; CACHE, TTT ray depth where alpha >= 0.5 else R7; R7_TTT_GEO sqrt(R7 x TTT); R7_CACHE_GEO sqrt(R7 x CACHE); R7_TTT (R7 + TTT) / 2. Regions ALL, NEAR7, FAR7. 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.
