This workspace stores durable narrowed problem briefs for very complicated work.

Use numbered JSON files such as `001-auth-boundary.json` or `002-release-smoke-gap.json`.
Each file should isolate one actionable problem and stay small enough to hand off to `plan` or `implement` without re-reading the entire original request.

Recommended fields:
- `id`
- `title`
- `status`
- `source_request`
- `narrowed_problem`
- `constraints`
- `unknowns`
- `acceptance_criteria`
- `next_skill`
