Seven-Phase Lifecycle: State Transitions
Formal state machine: the seven phases, their states, transitions, and guard conditions.
About this course
Vertical stack context: DOSFIUniversity (research) → DOSFI Academy (this course) → MeshNativeExchange (publishing & monetizing). Students progress from Learning → Building → Publishing → Monetizing. This module treats the transport lifecycle as a formal state machine. Seven phases — Submit, Validate, Enrich, Route, Meter, Transit, Settle — correspond to seven well-defined bundle states. Transitions are guarded by adapter outputs. The machine is deterministic and total over expected inputs; every reachable state and transition is enumerated. This module provides an advanced architectural analysis of the Seven-Phase Lifecycle within the Mesh-Native ecosystem, specifically focusing on state transition mechanics for DIU nodes. Learners will explore the deterministic nature of state transitions in the Transport Layer, the interaction between MeshInfer and the MNE, and how Identity Fabric and Privacy Tier configurations mandate specific transitions during workflow execution. This curriculum is designed to equip developers with the technical depth required to manage, monitor, and debug state-critical deployments in production Mesh-Native environments.
