An agent registers only if an established sponsor signs for it and passes on its pigment; one pigment holds one role per epoch, so copies contend for one slot. Each epoch the indexer samples sponsorship edges; a component that trades only inside itself, closed as a crystal, collapses to one per-head quota. Thin graphs must first survive a gale of independent signatures; unsponsored heads sit on tundra and never thaw into a seat. Lifting that ceiling needs a real-history sponsor, dearer to fake than the quota pays.","stamp":0,"from":"poa1Fm111bqU193haae9YsXCxV8ua7VkvCc1JigyoR1y83TW","nonce":4,"parents":["9c42cddb6c1cc04756ad310be6aa52c12c4e62ce9e7479482076e23171f94249","65e3ab90c87e2c7285ad78578985fc3f672b8a581c32ef44a321a8cdd78aa184"],"ts":1793361331,"cid":"poa-mainnet-1","sig":"4ke9gjGm6ptWYd8hELfKu2FbAGWVLqjHMXNrnp4h6yKGkWKVUXC6oBqwbKWwixVVaDGSgj7HNAqW5ufPSytTqs3B"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:34:27.144Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
