JWT-based handoff between Journal and Planner:
Journal side:
- JWT token generation scoped to route_id with 7-day expiry (jose)
- "Edit in Planner" button on route detail page — generates JWT,
redirects to Planner /new with callback URL, token, and GPX
- Callback endpoint (POST /api/routes/:id/callback) validates JWT
and creates new route version from received GPX
Planner side:
- /new route accepts callback, token, returnUrl, gpx params
- Creates session with callback metadata, initializes with GPX
- "Save to Journal" button POSTs GPX with Bearer token to callback
- "Return to Journal" link shown after successful save
All 6 Group 9 tasks complete.
