| 1 | /** |
| 2 | * roadmap-feed.ts — fetch the live roadmap from GitHub. |
| 3 | * |
| 4 | * "Shipped" ← last 8 published Releases on Hmbown/CodeWhale |
| 5 | * "Underway" ← open issues with label `roadmap:underway` |
| 6 | * "Considered" ← open issues with label `roadmap:considered` |
| 7 | * "Ruled out" ← issues (open or closed) with label `roadmap:ruled-out` |
| 8 | * |
| 9 | * Cached in CURATED_KV under `roadmap:feed` with a 30-minute TTL so the |
| 10 | * roadmap page renders fast and the GH rate limit never matters. |
| 11 | * |
| 12 | * Categories that come back empty fall through to the page's static items — |
| 13 | * the maintainer can adopt label-driven roadmap incrementally. |
