The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our experiments show that SkyScraper successfully finds 5x more events than traditional geocoding methods, demonstrating that agentic feedback is an effective strategy for surfacing new multi-temporal events in satellite imagery.

C2weakest assumption

That the multi-agent system can accurately geocode news events to visible changes in satellite imagery sequences and generate reliable captions without high rates of false positives or incorrect descriptions.

C3one line summary

SkyScraper uses iterative multi-agent feedback to geocode news articles and synthesize captions for satellite image sequences, locating 5x more events than traditional methods and producing a new 5,000-sequence dataset.
