The Ark has not yet onboarded a Nostr key. A signed application cannot reach them here yet. The steward will announce arrival on the community page when ready.
What happens next
Your application becomes a signed addressable Nostr event (kind 30408) and reaches the steward via relay. A best-effort direct message nudges them too.
The steward reviews on their dashboard. They can mark it viewed, in conversation, filled, or declined — each transition is a signed event you will see on your side.
Conversation moves into direct messages when both sides are ready. The first public line here is the one you will both remember.
