All examples use the same fictional project (SAP-Peças, a self-service parts ordering portal) and are consistent with one another from the spike to the Go/No-Go: same requirements (RF/RNF), same risks (RISK-NNN), same decisions (ADR-NNN), same characters. Together they form a complete, navigable reference case.
