Explanation: Delivering Integrated Value and Preventing Functional Silos

This document explores how SpecOps avoids the "Silo of Mocked Perfection" and guarantees end-to-end integration across autonomous AI coding workflows.

For the comprehensive architectural treatise, see Delivering Real Integrated Value.

The Failure Mode of Horizontal Layers

When multi-agent teams decompose software into horizontal layers (database tables, API controllers, frontend views):

• Each layer is authored in a separate work stream or agent session.
• Agents rely heavily on mocks to satisfy isolated unit tests.
• When layers are finally assembled, incompatible assumptions and contract mismatches cause widespread breakage.

How SpecOps Enforces Integration

1. Thin Vertical Slicing: Every task generated by spec-ops prd decompose touches the necessary layers to complete one user-observable behavior.
2. Blackbox Frontdoors: Tests must invoke public interfaces (CLI, HTTP, domain events) rather than reaching into private internals.
3. Executable Gherkin Scenarios: The acceptance criteria of user stories are executed as integration tests.
4. Relational Graph Lineage: The ProjectGraph ensures no task is executed unless it traces back to an accepted User Story and PRD.
