query: pending SH records join at live tip - #207
Merged
Conversation
Durable seed still lags accept, but collected create records sit on the write-behind job. Wallet SH reads merge those with the index and pin that visible height so mempool can drop confirmed txs without a hole between confirmed overlay and lagging Class B.

#207 joins pending creates at live tip, but rbtc-sh-wb popped the job before the watermark advanced. generate's drain then saw an empty queue while apply was still running, MiniWallet scantxoutset pinned the pre-tip view, and a spent coin looked live (bip68 orphaned). Hold the job in sh_applying until apply finishes so pending join covers that window.

Why
#206 left scripthash durable seed off the tip-accept path and pinned
wallet SH reads at the SH watermark. Mempool still drops confirmed
txs at live tip. Between those two, a tx can vanish: gone from
mempool, not yet in the lagging SH snapshot.
What
Collect create records onto the write-behind job at enqueue (cheap).
SH history/balance/utxo merge those RAM records with the durable
index and pin that visible height (live tip while jobs sit in RAM).
Durable
put_createseed still happens onrbtc-sh-wb.Accept still does not wait on locate_head.
