About the Reference Case

ExampleCo and its Enterprise Evidence Assistant (EEA) are fictional teaching examples. Their source documents, questions, identities, approvals, operational events, and financial figures were created for this book. They are not redacted organizational records.

The architecture is a proposed reference design developed from the teaching requirements and broadly applicable enterprise AI concepts. It expresses the author's professional judgment about design choices, trade-offs, and validation. It does not report an employer implementation. Public technical specifications and independent references support external technical claims.

The exercises use a fixed fictional test date of 15 April 2030. Document intervals and approval events are interpreted within that test period. The financial model covers a separate first full twelve-month operating year; its forecast and modeled outcome are synthetic and do not represent observed commercial results.

The companion's case.json is the shared specification for documents, questions, roles, workflow states, and economics. All amounts are in US dollars. Source references identify a document, version, and passage; for example, EXPENSE@2:p1 is passage 1 of version 2 of the expense policy.

The offline companion implements a deliberately small deterministic control exercise. Semantic retrieval, model-connected drafting, protocol adapters, production identity, distributed processing, and external business actions are design extensions unless explicitly identified as implemented. The book does not treat fixture success as a statistical estimate of model quality.
