Names were still absent after fixing the confidence denominator, because no
vote was being cast at all. The cause is that `ATTRIBUTION_SETTLE` was doing
duty for two unrelated quantities.
It was written for one: how long node reports take to spread across the network
once telemetry has the block. Eight seconds is right for that. But the lookup
also has to wait out a second quantity nobody had measured — how far behind the
chain the feed itself runs. On Planck the two coincide, because ~240 nodes at a
13 s block time is ~18 reports a second and the feed keeps up. Mainnet is ~190
nodes at ~1 s, an order of magnitude more traffic, and the feed sits about 57
blocks back. Measured against the node: chain tip 9539, highest height the feed
had reported in the preceding 110 s was 9482.
So every lookup asked who reported a block roughly fifty seconds before
telemetry had heard of it. `first_import` missed every time, every observation
became an abstention, and no author was ever named.
The join now retries every 5 s until the feed reaches the block, giving up at
three minutes and recording an honest abstention then. It adapts to whatever
the lag is rather than assuming it is zero.
Confirmed live: the top miner resolved to `QUANPOOL - quanpool-com` at
confidence 1.00 within about two minutes of restart, from 3 votes cast over 21
blocks. That 3-of-21 is also why the previous commit was necessary and not
sufficient — under the old denominator it would have scored 0.15 against a 0.6
bar and stayed nameless.
