The vecino/market view had three gaps: - Publishing inventory duplicated the listing. discover() appended every offer the relay streamed, but relays legitimately resend an addressable NIP-99 event (stored copy + live echo on publish). Merge by (authorPubkeyHex, id) so each offer appears once; two authors reusing a lot id stay distinct. - No product detail. Tapping a card jumped straight to chat. Add a read-only "product page" (MarketOfferDetailScreen) with title, mode, category, eco badge, coarse location, price, a "Shared by" seller section (profile fetched by pubkey) and the message button. Reached via a new /market/offer route; cards are now fully tappable. Shows only what the network already carries — no photos/description added to the wire. - No filters. Add a filter bar (type, category, eco) mirroring inventory, each chip group shown only when a discovered offer can match it. To make the eco filter real, publish the organic flag on the wire: Offer.isOrganic -> NIP-99 'organic' tag -> OfferMapper -> ShareableLot. Tests: commons_core organic round-trip; app-side dedup, two-author separation, filter logic, mapper passthrough; detail-screen widget tests. i18n keys added to en/es/pt/ast and slang regenerated.
