- H13 offer threads: the seller is ALWAYS the listing author (derived from the
event pubkey), never a self-declared role tag — a non-owner can no longer
appear as the seller with a payment pointer.
- H12 trade reputation: a preimage/deposit proof counts at most once, so a real
payment can't be reused across attestations to inflate payment-verified.
- Crew alerts: listed crews are filtered against the user's own membership
confirmation labels (one batched query), so a confirmed member no longer gets
a phantom 'confirm to join' badge/notification when the crew is edited.
- Error boundaries (app + route) and DesktopNavManager are translated; the
class boundary renders a translated functional ErrorFallback. New batch4
namespaces errorsUi.* / desktopNav.*.
