# Requirements

This section stores explicit product intent, constraints, and open questions.

## When To Read

- Understand confirmed project behavior, scope, constraints, or unresolved product intent.

## Key Files

- [Product brief](./product-brief.md)
- [Functional requirements](./functional/INDEX.md)
- [Non-functional requirements](./non-functional/INDEX.md)
- [Constraints](./constraints.md)
- [Open questions](./open-questions.md)

## Placeholders Or Stale Areas

- `product-brief.md` is still a placeholder (project identity lives in
  [PROJECT.md](../PROJECT.md)); fill or remove during the next update.
