…ter and group deletion issues - Reset DPR on scaled tray icon logo to fix counter misalignment at high DPI AyuAssets::currentAppLogo() sets devicePixelRatio to style::DevicePixelRatio() (e.g. 2.0 at 200% scaling). After scaledToWidth() Qt preserves that DPR, making the logical canvas smaller than args.size while WithSmallCounter uses args.size as drawing coordinates — causing the badge to render partially outside bounds (visible as a grey triangle). Upstream loads from PNG files (DPR=1), so this mismatch only affects AyuGram. Fixes AyuGram#310 - Save and display media in message history Deleted/edited messages with media (photos, videos, voice notes, stickers, etc.) only stored a text placeholder. Media metadata was never serialized to the DB and the history viewer always passed MTP_messageMediaEmpty() to makeMessage(). Added kDocumentType* constants, AyuMapper::mapMediaToMessage() to serialize MTPInputDocument/MTPInputPhoto into documentSerialized, and resolveMedia() lambda in GenerateItems() to reconstruct MTPDocument/MTPPhoto with proper attributes (video, sticker, voice, audio, animated) for correct rendering - Save media-only deleted messages with type placeholder - Show delete own messages option for admins and creators in groups - Save expired TTL messages deleted via auto-delete in groups - Remove deleted messages from shared media index to fix incorrect counts

Problem
Deleted and edited messages with media (photos, videos, voice notes, stickers, GIFs, etc.) were stored in the database with a stub
mediaPath = "/"anddocumentType = 0. The history viewer always passedMTP_messageMediaEmpty()tomakeMessage(), so real media was never shown — only a text placeholder like "Photo" or "Video".Solution
Storage (
ayu_mapper.cpp,messages_storage.cpp):kDocumentType*constants for media type classificationAyuMapper::mapMediaToMessage()which serializesMTPInputDocument/MTPInputPhotointodocumentSerialized, setsdocumentType,mimeType, andmediaPathif the file is locally cachedmap()with a singleAyuMapper::mapMediaToMessage(item, message)callDisplay (
history_item.cpp):resolveMedia()lambda inGenerateItems()that deserializes the stored input, looks up the document/photo from session cache, and reconstructs a minimalMTPDocument/MTPPhotoDocumentDatapublic API: video (withround_message/supports_streamingflags), animated, sticker, audio/song, voice — so media renders with correct icons and controlsNotes
