Reported from the live site: a name would appear and then be "often forgotten
if it doesn't mine a new block within the window".
`attribute` dropped the held key the moment the vote window contained no vote
for it. That reads silence as contradiction — the same mistake as counting
abstentions in the confidence denominator, one layer further on. The window
holds twenty observations and mainnet resolves a first reporter on roughly one
block in seven, so an incumbent's votes routinely roll out before any
replacement earns one. The name vanished at that moment and the row fell back
to the raw preimage until three fresh votes rebuilt it.
A held name is now replaced rather than dropped: it stands until a different
node leads it by `TAKEOVER_MARGIN`. The margin is the other half of the same
problem — a window carrying about three cast votes flips on a single vote under
a bare majority rule, and pools demonstrably run several nodes that all report
their blocks (this miner has answered to both `QUANPOOL - quanpool-com` and
`quanpool-payout-mainnet`). Requiring a lead of two rides that out instead of
oscillating between siblings.
Takeover after a restart or rename still works, and is still tested: a node
that genuinely owns the blocks accumulates votes and passes the margin within a
few blocks.
