rota-brainstorm — Per-item Design

Sits between /rota-capture (what) and /rota-plan (how). Scope is one backlog item (#N; file backend B07/F03/T05); project-level exploration is /rota-vision. The design (rota design show <ID>) is soft input to /rota-plan, never required. Milestone tags are context only.

Copy this checklist and track your progress:

- [ ] Step 1 — Resolve target
- [ ] Step 2 — Load context
- [ ] Step 3 — One draft
- [ ] Step 4 — One approval
- [ ] Step 5 — Store

Step 1 — Resolve target

Target: #N / bare number (issue backend) or [BFT]\d{2,} (file backend), plus optional --grill (Step 3). Reject milestone and slice IDs: "/rota-brainstorm operates on a single backlog item. For project-level exploration use /rota-vision; for slice planning use /rota-plan." rota item field get <ID> --name title exits 3 for an unknown item: refuse and point at /rota-capture.

If a design exists, ask once (View / Edit / Replace, default View): View runs rota design show <ID> and exits; Edit loads it as the starting draft; Replace runs rota design rm <ID> first.
