The Exporter Was Easy. Making It Deterministic Was the Work.

Short summary

A developer built a mobile export pipeline that prioritizes determinism through pure serializers, injectable IO ports, and audit logging. Key insight: when using AI heavily in engineering, the fix isn't less AI but stronger architectural boundaries—pure transformations, deterministic outputs, and clear seams between concerns. This pattern makes adding new export formats safe, testable, and fast without rewrites.

• •Deterministic exports through pure functions separated from side effects
• •Dependency injection enables both production and test execution without mocks
• •Architectural seams make AI-assisted development faster and safer
