Mesh Model #

The mesh is a live representation of system structure.

Each deployed service instance corresponds to a graph node.

The mesh exists in two forms:

• Dev Mesh (experimental)
• Prod Mesh (stable)

Dev Mesh #

The Dev Mesh is:

• Forkable
• Propagation-enabled
• Test-gated
• Disposable

When a contract changes, a subgraph is forked into Dev Mesh.

Dependent services are updated within this fork.

Prod Mesh #

The Prod Mesh:

• Contains validated nodes
• Is mutation-resistant
• Accepts only promoted graph states

Promotion is atomic at the graph level.

Mesh as State #

The mesh is not just deployment topology.

It represents:

• Service versions
• Contract versions
• Dependency edges
• Validation status

The mesh is architecture encoded as runtime state.
