Conclusion status
No confirmed conclusion exists for this pair. The evidence below is presented for transparency; a relationship conclusion requires a human review that has not happened, or a previous decision no longer matches the current evidence.
Evidence suggests ecrc/exageostatcpp may succeed ecrc/exageostat (directional claim found). Human review required before publication.
Seed context: 2026-09-23 researched; NOT APPROVED; pending normal evidence collection. Source README says active development moved to ExaGeoStatCPP and source is no longer maintained. New distinct repo has a 2026-05 push. The migration also changes C to C++ and adds R installation; no compatibility claim. Sources: https://github.com/ecrc/exageostat and https://github.com/ecrc/ExaGeoStatCPP. Canonical GitHub IDs 109120150 -> 717771886. Raw API snapshot: succession-research-20260923.json.
Evidence (1)
Verbatim excerpts from official sources, whitespace-normalized. Full payloads are hashed and retained by the pipeline; collection failures never fabricate evidence.

Timeline
“Event time” is an upstream timestamp when the source provides one; “first observed” is when this project saw it. They are deliberately separate columns.
