BPMN Core Execution in MEMM: distributed execution with a clear ownership boundary

MEMM separates workflow identity from the current physical execution environment. State-changing execution stays bound to a named local ownership boundary; cluster-wide views and ownership changes are treated as explicit distributed operations.

Implemented engineering foundation

The product owner confirms completion of the bounded BPMN engineering scope. Public wording is limited to architecture principles, responsibility boundaries and technical effects.

Architecture principles of the runtime foundation

  • Stable logical placement of workflow identity at a responsible execution boundary.
  • Localized state changes instead of an implicit cluster-wide write transaction.
  • Explicit distributed read views instead of hidden global database semantics.
  • Fail-closed ownership when routing state is unclear or contradictory.
  • Recoverable ownership transfer as a controlled operating action.

Why this matters for long-lived workflows

Workflows can outlive individual deployments. A logical ownership boundary keeps business process identity stable while infrastructure can evolve in a controlled way.

The public page describes the technical effect rather than the mechanism used to achieve it.

What this page explicitly does not claim: Implementation details, operating parameters and internal verification procedures are outside the public product documentation.
