No active same-category alternatives in the registry yet. The tools index carries everything else that is live.
How this was decided
Not an editorial call. Openlayer's check failed three syncs in a
row, and the 3-miss rule marks it
discontinued automatically. If the vendor page comes back, the
registry restores it on its own: warn first, then
active. Both directions are recorded as events.
