Consolidates 137 wave commits + 31 supporting commits (CLAUDE.md bump, typealias additions, AnyObject→EngineMedia restoration) into one squashed commit. Migrates dozens of consumer-side public APIs, struct fields, protocol methods, and enum payloads from Postbox protocols/structs to TelegramEngine engine wrappers and typealiases. Drops `import Postbox` from many files. Adds new TelegramCore typealiases and one TelegramEngineUnauthorized facade. Notable changes by category: **TelegramCore typealias additions** (rule 2 — narrow utility typealiases): - EngineChatListIndex, EngineTempBoxFile, EngineItemCollectionItemIndex, EngineItemCollectionViewEntryIndex, EngineValueBoxEncryptionParameters, EngineMessageAndThreadId, EnginePeerStoryStats, EngineMessageHistoryAnchorIndex, EngineChatListTotalUnreadStateCategory, EngineChatListTotalUnreadStateStats, EnginePeerSummaryCounterTags, EngineChatListTotalUnreadState, EngineItemCacheEntryId, EngineHashFunctions, EngineCachedMediaResourceRepresentationResult, EngineMediaResourceDataFetchResult, EngineMediaResourceDataFetchError, EngineMediaResourceStatus, EngineCachedPeerData **TelegramCore engine extensions/forwarders**: - EngineMessage.engineMedia, EngineMessage.enginePeers, EngineMessage.adAttribute, EngineMessage.effectivelyIncoming - engineFileSize forwarder - TelegramEngine.Resources.clearCachedMediaResources(mediaResourceIds: Set<EngineMediaResource.Id>) - TelegramEngine.Resources.fetchStatus(id:resourceSize:) - TelegramEngineUnauthorized.UnauthorizedResources facade with storeResourceData **Public API/struct migrations to engine types**: - ChatAvailableMessageActions.banAuthor/banAuthors → EnginePeer?/[EnginePeer] - WebSessionsContextState.peers → [EnginePeer.Id: EnginePeer] - CacheUsageStats.peers → [EnginePeer.Id: EnginePeer] - PeerCommand.peer → EnginePeer - PeerInfoControllerMode.calls(messages:) → [EngineMessage] - CallControllerNodeProtocol.updatePeer → EnginePeer params - ChatHistoryListNode.messageInCurrentHistoryView (and 4 variants) → EngineMessage? - ChatHistorySearchContainerNode.messageForGallery → EngineMessage? - PeerInfoPaneNode.findLoadedMessage / ensureMessageIsVisible / transitionNodeForGallery → engine-typed - GalleryHiddenMediaTarget.getTransitionInfo / GalleryHiddenMediaManager.findTarget → engine-typed - ChatPanelInterfaceInteraction.presentReactionDeletionOptions / presentBan*MessageOptions → EnginePeer - DrawingMessageRenderer.messages → [EngineMessage] - ChatVideoGalleryItemScrubberView.setFetchStatusSignal → EngineMediaResource.FetchStatus - ChannelDiscussionGroupActionSheetItem.peer, VoiceChatPeerEntry.peer, VoiceChatFullscreenParticipantItem.peer, MediaStreamComponent.chatPeer, MediaStreamVideoComponent.callPeer, ChatMessageContactBubbleContentNode.contactPeer, ChatMessageForwardInfoNode.peer, ChatMessageCommentFooterContentNode.replyPeers, ChatReportPeerTitlePanelNode.peer, ChatMessageActionUrlAuthController.bot, PeerMediaCollectionInterfaceState.peer, ChatMessageCallBubbleContentNode.peopleAvatars, ChatLoadingNode.renderedPeer (→ EngineRenderedPeer) — all to engine types **Wave-71-shadow stored-field migrations** (Postbox Peer/Message → Engine wrapper): - LegacyCallControllerNode.peer - CallStatusBarNode.currentPeer **Dead-code / dead-field removals**: - CallController.peer, CallControllerNodeV2.account, ContactMultiselectionController PeerNameIndex fields, preparedChatListNodeViewTransition account: Account param, FetchResource.swift entirely (unused function) **Module-level Postbox import drops**: 30+ files including TelegramRootController, EditStories, GiftViewScreen, AnimatedStickerUtils, FetchPhotoLibraryImageResource, PeerInfoGiftsPaneNode, PeerInfoPaneContainerNode, PresentAddMembers, PeerInfoProfileItems, ChatControllerAdminBanUsers, PresentationData typealiases, DefaultDayPresentationTheme, ChatListViewTransition, GalleryHiddenMediaManager, RecentSessionsController, GifContext, AuthorizationSequenceController, PeerInfoHeaderEditingContentNode, PeerInfoHeaderNode, PeerAllowedReactionListController, CallControllerNodeV2, and 6 PeerInfo pane files. **AnyObject restoration**: rule 8 added (never substitute Postbox protocols with Any/AnyObject) — undid previous AnyObject substitutions in waves 141/143 back to EngineMedia. Doc maintenance: CLAUDE.md updated to reflect new typealiases and forwarders. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
