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.
