RealityPatch

Agents keep executing plans built on facts that are no longer true. RealityPatch versions every fact in MongoDB, tracks which plan steps depend on which fact version, and when reality is corrected it reverses the affected actions, rolls back, and re-plans — propagated live to running agents via change streams.
