## Notes

- **`eolStatus`** is a derived projection (`active` / `eol` / `ongoing` / `null`) computed against today's UTC date — agents can answer "is this version still supported?" without parsing dates.
- **Boolean dates → strings.** endoflife.date sometimes ships `true` for "ongoing support" / `false` for "no LTS". The adapter normalises:
  - `true` → `"ongoing"`
  - `false` / `null` → `null`
  - ISO date string → returned as-is
- **No API key required.** Slugs are exactly what appears at `https://endoflife.date/<product>`.
- **Errors.** Bad slug shape → `ArgumentError`; unknown product → `EmptyResultError` (HTTP 404); rate-limited → `CommandExecutionError`.
