Praxist hits 4,817 stars in four days by treating research campaigns as lineages, not runs
Sapient's Praxist repo was created 2026-08-27 and reached 4,817 stars by 2026-08-31, backed by an arXiv paper (2608.25955, 2026-08-26) that names the structural problem it targets: autonomous R&D systems treat each attempt as self-contained, so logs and search trees record what happened without establishing which design element caused an improvement or whether its evidence survived validation, and long campaigns keep re-learning the same lessons. Praxist converts reproducible artifacts and evaluator outcomes into a typed evidence graph of findings, lane-structured frontiers and agendas, separating local artifact construction from cohort-level synthesis. It installs into Codex or Claude Code and has a Codex-native mode that runs off an existing subscription without an API key.
