Postbox refactor waves 138–276: 168-commit squash
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.
