Agents get reads wrong. That's annoying. They get writes wrong. That's a production incident. Manifold is the write layer for LLM agents. Connect any SDK or API. Manifold discovers your data model, maps relationships across systems at build time, and guarantees every write propagates correctly — right field, right format, right system. Every time. Build-time LLM. Runtime deterministic. No guessing. No drift. No corrupted data at 2am.
