Architecture, contracts, runtime orchestration, and evidence-driven release policy.
This hub maps event flow, gateway trust, tenant isolation, contract strictness, and release gate behavior to concrete implementation and validation artifacts.

Engineering decision map
Runtime behavior is constrained by architecture decisions and test gates. Changes are expected to maintain contract compatibility and release evidence freshness.
Event-native services
Service boundaries follow event contracts and explicit failure handling with tenant-safe DLQ patterns.
Release gates
Preflight, contract tests, security regressions, and upstream CI freshness checks are mandatory before go/no-go.
Observability + proof
Every release decision references validator logs, control matrix state, and evidence index entries.
