The miner league from your scanned blocks, and which witnesses the Watch page follows. Everything stays in your browser — nothing is sent anywhere.
Which pools include the most OP_RETURNs over the 80/83-byte standard — an inclusion-policy scoreboard, ranked per block mined so hashrate share doesn't decide the table. Attribution is the pool's own coinbase tag, read from blocks this browser fetched and verified itself. When a chain split appears on the Watch page, this is each arm's form guide.
Which NIP-333 publishers and relays the Watch page polls (one per line). Explorer witnesses
(mempool.space, blockstream.info) are always on. Mesh witnesses join via a
?peer=wss://…&room=… link, or set them here. Changes apply when the Watch page reloads.
