Separate content, workflow, and persistent business records

Atlas assigns authored content and form definitions to Contentful, process/task state to Camunda, authentication identity to IAM, and durable business data to simulated systems of record. MuleSoft mediates experience and system APIs. Private file bytes live in document storage with business metadata and access relationships in a document registry.

The prototype uses one persistent backend simulator divided into logical business modules, plus document storage. This gives the six-product demo durable state and testable ownership boundaries while keeping its deployment scope bounded. It does not replace the requested Contentful, Camunda, or MuleSoft components with mocks.

Consequences

Applications, claims, saved answers, and customer documents are not CMS content. Workflow variables carry references and the minimum step data rather than becoming the master business record. Business identifiers remain distinct from platform identifiers. Linked records preserve the accepted employer and personal-access boundaries.

Each business module owns its updates. Task completion and business completion are separate facts, and cross-component work requires acknowledged, retry-safe commands, pending/recovery states, and reconciliation. The design cannot rely on one atomic transaction spanning the platforms.

The accepted workflow contract applies these boundaries to human decisions, fulfillment, payments, cancellation, and reconciliation. The form contract defines release binding. The Experience Layer contract and ADR 0005 define API and delivery boundaries. Exact schemas, storage products, runtime choices, and security mechanisms remain downstream. The ownership matrix and domain diagram define this decision's boundaries.

Evidence: the owner accepted the proposed model with "Yes. proceed" in Assign authoritative business records and domain boundaries.
