Virtual-bucket sharding: a logical placement boundary for distributed workflows

A virtual placement layer creates a stable logical boundary between workflow identity and current execution ownership. Infrastructure can therefore change without redefining the business identity of the process.

Architecture overview · intentionally excludes internal implementation detail

What is relevant publicly

Workflow identity remains decoupled from the current physical execution environment.
Ownership is resolved through an explicit logical routing boundary.
Unclear routing state is not hidden behind a silent default path.
Infrastructure changes can be controlled at the placement boundary.

Public framing

The website explains the logical product boundary and its effect. Detailed implementation is not part of that framing.

What this page explicitly does not claim: The public framing stays limited to the architecture principle, responsibility boundary and technical effect.
