PRD ↔ Spec
What it's for vs. how it's built — same artifact, two voices.
What it shows
The PRD names the user outcomes; the spec names the interfaces, data shapes, and acceptance tests. They live next to each other in the repo. If they disagree, the spec wins for code and the PRD wins for review.
Where it fits
