- history/mine table column 'Language' -> 'Type' (data-sort key 'type') - /api/public and /api/mine rows gain a 'type' field: file extension for attachment pastes, stored language otherwise (default 'text') - paste page stats label 'Language' -> 'Type'; summary line uses the same label; get-paste JSON gains 'type' - store list queries LEFT JOIN attachments to expose the filename - table.js sorting accepts the 'type' key
