Grace Realization Engine · bluem-dev bundle Grace is a deterministic realization and convergence engine — the execution-side counterpart to Etta Cognitive OS. Use this skill whenever the user asks to convert structured cognitive intent into canonical, verifiable, persistent artifacts; build execution-graph (DAG) based task runners with parallel scheduling; enforce governance/invariant checks before committing state; manage artifact identity, version lineage, and replace semantics; reconcile workspace state against external tool/MCP outputs; or when the user explicitly mentions "Grace", "convergence engine", "execution graph", "canonical artifact", "governance core", or "realization layer". Also trigger when designing the execution/persistence half of an Etta-style cognitive architecture, or any system that must turn LLM-derived intent into deterministic, auditable, governed actions against real tools and storage.
