Mapper, wrapper and validator

Describe data fields centrally and validate request-to-model transitions.

01

Structured models

Mapper definitions identify sources, fields and types for application data.

02

Early validation

Validators reject invalid input before persistence and wrappers expose consistent model access.

03

Visual result

Examples are deterministic previews. PHP and shell code is never executed in the browser or on the public server.
