visionA learned matcher (SuperPoint+LightGlue, L4, 09-03) took registration from 31.9% to 59.1% at the same cost per registered frame and 8.7× faster than loop detection — but components went 22 → 39 and the largest shrank 122 → 75 frames. The matcher was worth ~2×; it cannot join a scene the camera never tied together. Next lever is capture, not another matcher. Closed as an algorithm questionOURS
All three GPU lanes are open
AWSOPEN 2026-09-03 — the operator upgraded the account off AWS's Free Plan and a real g4dn.xlarge (Tesla T4) launched, ran FluidX3D from the same image digest as the other two clouds, and scored 2,793 MLUPs/s. The SCP still denies Spot and us-east-1; on-demand in us-east-2 is what the lane usesDONE
GCPCLEARED 2026-08-31 — trial upgraded. T4×8, L4×16, V100×8, 3000 vCPU; a real T4 instance launched and was deleted. GPUS_ALL_REGIONS is gone from project-info entirelyDONE
