Durable execution (checkpointing) and human-in-the-loop are genuinely hard problems in agent systems; solving them at the framework level instead of requiring manual implementation is signal. Inspired by Pregel/Beam, which is the kind of genealogy that matters. The slop score reflects: (1) unavoidable marketing noise in README, (2) integration gravity toward the LangSmith ecosystem, (3) 'trusted b...
