S-9: CurrentAsOf() returned the maximum shard-log sequence across every
shard the database holds, but that sequence is a per-shard counter -
mixing shards' counters together could report a page as exact "as of" a
sequence a different, untouched shard advanced to while the page's own
shard sat still. CultNetDatabase gains CurrentAsOf(shardId), the watermark
of one shard's own log, and CultNetDocumentRegistry.SelectPage now scopes
asOf to the single shard EnsureSingleShard already resolves the matched
rows to, falling back to the caller-supplied value only when the selection
matches no rows.
S-11: CultNetDatabaseServer.HandleSubscribeV1Async refused a hop-bearing
selection before running the door (Validate), so a selection invalid for
an unrelated reason (an empty keys list, an undeclared index, ...) got a
hop refusal that had nothing to do with why it was actually rejected. The
door now runs first, unconditionally. The hop refusal also always named
the field "cites" even when the selection carried Cited instead; it now
names whichever hop is actually set.
