Aion Framework: External Architecture Summary

Aion is a contract-first architecture for declarative graph modules. At the boundary, authors define module manifests and objects using typed schemas; the compiler resolves and validates module content into deterministic bundles; the engine performs install planning and lifecycle application; and Studio MCP exposes these capabilities through stable request and response envelopes. The architecture enforces explicit boundaries between authoring, compile-time validation, runtime lifecycle execution, and integration sidecars, with compatibility rules and CI gates governing evolution. This creates a clear system model where guarantees are tied to contracts and verifiable checks, not implicit conventions.
