Converting an approved spec into an engineering plan requires generating a restartable plan artifact that structures sequenced milestones, interfaces, and validation checkpoints. This ensures implementation steps remain buildable and testable throughout execution.

A restartable engineering plan artifact is a self-contained document that defines execution status, recovery notes, and explicit validation commands. It allows implementers to confidently resume incomplete work without losing context or skipping build and test checkpoints.

Structuring implementation milestones with validation checkpoints involves breaking down spec acceptance into sequenced, buildable steps that conclude with a final command validation. This approach prevents costly rework by verifying each milestone independently before proceeding.

Updating an existing workflow plan incorporates accepted review feedback without silently expanding scope. Product-contract gaps identified during updates are routed back to the spec creation phase to maintain strict boundary control.

Engineering planning applies to both greenfield development and enhancement updates. It turns spec acceptance into concrete execution steps, ensuring sequenced milestones and recovery notes are generated regardless of whether the project is new or existing.
