ckpool reward address (coinbase-extracted)

Received block rewards as part of ckpool's coinbase output across 5 block(s) between heights 496708 and 532376. Attribution derived from on-chain coinbase scriptSig tag matching plus Jameson Lopp's blocks.csv mapping; this is hard evidence the address received pool rewards under that pool's signature, not clustering inference.
