Reviewed both pages at desktop and phone widths. Desktop was fine; on
phones three things were wrong. The top bar wrapped into four rows
because the font-comparison pill and full-size links all stayed; on
screens under 640px the pill is hidden and links and buttons tighten.
The dashboard menu rendered as five full-width blocks because the
wide-screen width:100% rule outranked the phone override; it is now a
row of pills, the wallet block collapses to one line (short address,
live balance, refresh), and the sub-tabs scroll sideways instead of
wrapping. The long address had also been pushing the whole page wider
than the viewport, fixed with minmax(0,1fr) on the grid column.
The market showed an empty filter bar and a one-line status when there
were no listings; it now shows a proper empty state with the two things
a visitor can do (sell from the dashboard, register a new name) and
hides the filters until there is something to filter. Buy buttons go
full width on phones.
Two gaps the owner panel left open. First, a hidden TLD was only a UI
gate: anyone could still broadcast a REG under it and every indexer
admitted it. Second, there was no way to sell a name without trusting
the other side.
Co-sign rule (consensus, applied in lockstep by bns.js and
resolver-web.js): a REG under a TLD whose records at that height say
policy "cosign" or hidden 1 is indexed only if the transaction carries
the TLD's own certificate. The certificate can only be spent by the
owner's key and is re-issued to them in the same transaction, so it is
a co-signature nobody can forge and nothing is consumed. The TLD map
now keeps the TUPD timeline so policy is evaluated at the REG height.
Owners register under their private TLDs with the certificate added
from their own wallet; third parties under a "cosign" TLD build the
full transaction, sign their inputs and queue it at /api/cosign, where
the owner approves it from the dashboard (signCosignRequest refuses to
sign unless the certificate returns to the same locking script).
Marketplace: a listing is the seller's certificate input plus a price
output signed SIGHASH_SINGLE|ANYONECANPAY, stored by the gateway as a
bulletin board (/api/market, verified against the on-chain owner and
pruned when the certificate moves). The buyer completes it in one
transaction, so the seller is paid exactly when the name moves.
Cancelling also spends the certificate once so the offer is void.
Site: market.html, Sell sub-tab and Pending approvals in the portal,
Market link in nav and footer, six dictionaries extended, cache tags
bumped. Verified on chipnet: cosigned.sc registered by a throwaway
wallet through the queue with the .sc certificate back at the owner;
aloevera.test listed and delisted through the API.
Ariadne's resolver-web.js copy and the mobile Bns.java port still need
the co-sign rule; until then they admit REGs this index rejects.
