Software block architecture

A consistent shape for every component so it is testable, observable, and safe to promote.

We define a standard block shape with explicit inputs, outputs, tests, and observability so systems stay composable as they grow.

  • Every block follows the same shape.
  • Inputs and outputs are explicit contracts.
  • Tests and observability ship with the block.
  • Blocks can be promoted or replaced in isolation.

The shape of a block

Every block has the same shape so components can be composed, tested, and replaced safely.

  • Defined inputs with schemas.
  • Defined outputs with schemas.
  • Processing logic separated from I/O.
  • Contracts and tests.
  • Observability built-in.
