Design for auto-scrolling the ResizableSheetComponent scroll view on text
change so the caret in either ListMultilineTextFieldItemComponent stays
visible above the soft keyboard.
Six-task implementation plan covering the parser / resolver / codegen
extension path described in the 2026-04-21 design spec. Tasks land
end-to-end, with a final Bazel build verification of the regenerated
SecretApiLayer*.swift files.

Adds the design spec for extending SwiftTL to parse TL schemas
with ===N=== layer markers (secret_scheme.tl), emitting one
cumulative-snapshot Swift file per declared layer. Flat schemas
are unchanged. No CLI surface changes.

Replace the Ruby decrypt.rb shell-out with a direct Python call to
decrypt_match_data(). The iOS build no longer depends on a Ruby
interpreter. Includes the spec, plan, AES-256 port, tightened error
surfaces for key length and V1 fallback, and the BuildConfiguration
wire-up that drops decrypt.rb.

Closes the last future-wave candidate from wave 8 by eliminating the
Icon.media(Media, ...) enum case in StorageFileListPanelComponent.swift
and dropping import Postbox. StorageUsageScreen (the module as a whole)
is now fully Postbox-free.
Icon enum split:
case media(Media, TelegramMediaImageRepresentation) ->
case mediaFile(TelegramMediaFile, TelegramMediaImageRepresentation)
case mediaImage(TelegramMediaImage, TelegramMediaImageRepresentation)
Equatable rewritten as switch-over-tuple with id-based equality per
concrete type (lFile.fileId == rFile.fileId / lImage.imageId ==
rImage.imageId), same semantics as the old media.id comparison.
Binding site: `if case let .media(media, representation)` +
`as? TelegramMediaFile` / `as? TelegramMediaImage` downcasts ->
compound case-binding `case let .mediaFile(_, representation), let
.mediaImage(_, representation):` to lift the shared representation
variable, plus an inner switch for the setSignal branch. The compiler-
enforced exhaustiveness of the split improves call-site safety.
Construction sites (2): `.media(file, representation)` -> `.mediaFile(
file, representation)`, `.media(image, representation)` -> `.mediaImage(
image, representation)`.
Placeholder fixup:
messageId: EngineMessage.Id(peerId: PeerId(namespace: PeerId.Namespace
._internalFromInt32Value(0), id: PeerId.Id._internalFromInt64Value(0)
), namespace: 0, id: 0)
->
messageId: EngineMessage.Id(peerId: component.context.account.peerId,
namespace: 0, id: 0)
Inside a measureItem layout-measurement instance. Caught by second-pass
build failure `cannot find 'PeerId' in scope`. PeerId / PeerId.Namespace
/ PeerId.Id are raw Postbox types (not TelegramCore typealiases —
consistent with wave 9's MessageId -> EngineMessage.Id fixup). Using
context.account.peerId is semantically equivalent for the measurement
use case (messageId only feeds image-fetch userLocation and Equatable
comparison, neither exercised for this standalone instance).
Net: 1 file changed, +22 / -29 lines.

Closes the first of the two future-wave candidates left open by wave 8 by
rewriting both AccountSpecificCacheStorageSettings preferences-view
observation sites in StorageUsageScreen.swift using engine APIs, and
drops import Postbox from that file.
Site 1 — cacheSettingsExceptionCount (former 1047-1087):
postbox.combinedView(keys: [.preferences(keys: Set([...]))]) +
PreferencesView ->
context.engine.data.subscribe(TelegramEngine.EngineData.Item
.Configuration.ApplicationSpecific-
Preference(key: ...))
+ preferencesEntry?.get(...)
Site 2 — peerExceptions (former 3131-3196):
- Same preferences-observation replacement as Site 1.
- postbox.transaction { transaction.getPeer / getPeerCachedData as?
CachedGroupData / CachedChannelData; FoundPeer(peer:subscribers:) }
-> context.engine.data.get(EngineDataMap(...TelegramEngine.Engine-
Data.Item.Peer.Peer.init(id:))) + pattern match on EnginePeer
.user / .secretChat / .legacyGroup / .channel
- Signal element: [(peer: FoundPeer, value: Int32)] -> [(peer: Engine-
Peer, value: Int32)]. FoundPeer wrapper and its `subscribers` field
dropped — computed but never read downstream (consumers only read
.isEmpty, .count, and .prefix(3).map { EnginePeer($0.peer.peer) }).
Consumer update:
peerExceptions.prefix(3).map { EnginePeer($0.peer.peer) } ->
.prefix(3).map { $0.peer }
Typealias fixup (caught by first-pass build failure):
var mergedMedia: [MessageId: Int64] -> [EngineMessage.Id: Int64]
(MessageId is raw Postbox; must use the EngineMessage.Id typealias
when import Postbox is removed.)
Reusable pattern documented in CLAUDE.md: TelegramEngine.EngineData.Item
.Configuration.ApplicationSpecificPreference(key: ValueBoxKey) is the
general-purpose engine replacement for the postbox.combinedView(keys:
[.preferences(keys: Set([key]))]) + PreferencesView idiom. Works from
any module importing TelegramCore (without import Postbox) because
passing PreferencesKeys.<name> keeps ValueBoxKey as an inferred-only
type that never gets named in the consumer.
Net: 1 file changed, +30 / -54.
StorageUsageScreen.swift is now Postbox-free. The wave 8 outcome's other
future candidate (StorageFileListPanelComponent.swift's Icon.media(Media,
...) enum case) remains — trivial future wave will land the whole-module
drop.

Narrow consumer-module migration of raw Message types to EngineMessage in
the StorageUsageScreen component. Two files touched; the module keeps
import Postbox because of two out-of-scope site clusters (preferences-
view observation + a Media-carrying Icon enum case) — both flagged in
CLAUDE.md and the wave doc as future-wave targets.
StorageUsageScreen.swift:
SelectionState.togglePeer(availableMessages:)
[EngineMessage.Id: Message] -> [EngineMessage.Id: EngineMessage]
AggregatedData.messages
[MessageId: Message] -> [EngineMessage.Id: EngineMessage]
AggregatedData.clearIncludeMessages / .clearExcludeMessages
[Message] -> [EngineMessage]
AggregatedData.init messages param — same swap
RenderResult.messages
[MessageId: Message] -> [EngineMessage.Id: EngineMessage]
openMessage(message: Message) -> openMessage(message: EngineMessage)
(unwrap to raw at OpenChatMessageParams
/ chatMediaListPreviewControllerData
call sites via ._asMessage())
StorageFileListPanelComponent.swift:
Item.message: Message -> EngineMessage
(internal .id / .timestamp / .media
usage compiles unchanged against the
EngineMessage class).
Wave-7 facade-boundary bridging dropped:
- renderStorageUsageStatsMessages call site: the .mapValues(EngineMessage.init)
on existingMessages and .mapValues { $0._asMessage() } on the result vanish;
AggregatedData.messages and RenderResult.messages are now engine-typed on
both sides of the facade.
- clearStorage call sites (2): the .map(EngineMessage.init) wraps around
includeMessages / excludeMessages vanish; locals become [EngineMessage].
- Inside AggregatedData.updateSelected... accumulation loop, four
item.message._asMessage() calls (where item.message was EngineMessage
and the target was [Message]) drop back to plain item.message.
- StorageMediaGridPanelComponent.Item(message: EngineMessage(message), ...)
at the RenderResult-build loop loses the EngineMessage(...) wrap since
`message` is already EngineMessage.
Out of scope (module keeps import Postbox):
- StorageUsageScreen.swift:1047-1062 / 3131-3185 — AccountSpecificCache-
StorageSettings observation via postbox.combinedView + PreferencesView
and a postbox.transaction block doing transaction.getPeer / getPeerCached-
Data as? CachedGroupData/CachedChannelData for peer-category classification.
- StorageFileListPanelComponent.swift:105 — Icon.media(Media, ...) enum case.
Constructed only as .media(TelegramMediaFile, ...) or .media(TelegramMedia-
Image, ...); trivial future wave to split into two cases.
Build verified green: 59s incremental, 27 actions, Telegram.ipa produced.

Closes the seven remaining raw-Postbox leaks in TelegramEngine public
facades surfaced by a post-wave-6 scouting pass (all non-permanently-
blocked candidates).
Facades migrated in place (6 rewrites + 1 deletion; all _internal_*
implementations unchanged per the "internal Postbox-facing stays raw"
rule):
Messages:
downloadMessage Signal<Message?> -> Signal<EngineMessage?>
topPeerActiveLiveLocationMessages Signal<(Peer?, [Message])> -> Signal<(EnginePeer?, [EngineMessage])>
getSynchronizeAutosaveItemOperations deleted (dead facade; sole caller uses _internal_ directly)
Peers:
updatedRemotePeer Signal<Peer> -> Signal<EnginePeer>
(PeerReference param kept; no EnginePeer.Reference alias today)
Resources:
renderStorageUsageStatsMessages [EngineMessage.Id: Message] -> [EngineMessage.Id: EngineMessage]
clearStorage(peerId: ...) [Message] -> [EngineMessage]
clearStorage(peerIds: ...) [Message] -> [EngineMessage]
clearStorage(messages:) [Message] -> [EngineMessage]
(no external callers; migrated for overload-set consistency)
Consumer call-site updates (5 files):
- ChatListSearchListPaneNode drop redundant .flatMap(EngineMessage.init) wrap
- LocationViewControllerNode drop redundant .map(EngineMessage.init) wrap
- LiveLocationSummaryManager drop redundant EnginePeer(...) / EngineMessage(...) ctors
- StorageUsageScreen bridge [Message] <-> [EngineMessage] at the 4 facade-call points
(internal [MessageId: Message] / [Message] storage kept;
full-consumer-module migration is out of scope)
Discovery: grep of TelegramEngine/*/TelegramEngine*.swift public signatures
for `: Postbox|: Account|: MediaBox|: MediaResource|: Peer\b|: Message\b|
-> Signal<.*(Peer|Message)` turned up these seven candidates and no others.
After this wave, the full TelegramEngine.* facade surface is engine-typed
modulo the four permanently-blocked TelegramMediaResource-conforming
classes recorded in CLAUDE.md (ICloudFileResource, InstantPageExternal-
MediaResource, VideoLibraryMediaResource, YoutubeEmbedStoryboardMedia-
Resource).
No modules became Postbox-free in this wave. Plan: docs/superpowers/
plans/2026-04-20-postbox-to-telegramengine-wave-7.md.
Full project build verified green.

First build-verified unused-import sweep: speculatively dropped
import Postbox from 782 consumer files (plain ^import Postbox$ lines,
excluding TelegramCore/Postbox/TelegramApi paths), iterated 18 full
project builds with --continueOnError, restored the import on every
file that failed to compile. 183 drops survived; 189 consumer modules
newly Postbox-free.
Bundled: spec + plan + C1 atomic batch drop + C2 CLAUDE.md outcome and
permanent methodology guidance under Wave-selection. The methodology
subsection captures the reusable playbook (--continueOnError is
essential, dependency graphs are deep so expect many iterations,
pattern-based preemptive restores accelerate convergence, and
CLAUDE.md's engine typealias cheat sheet arrows are migration targets
rather than typealiases in TelegramCore).

Migrates uploadSecureIdFile's public signature from (context:,
postbox: Postbox, network: Network, resource: MediaResource) to
(context:, engine: TelegramEngine, resource: EngineMediaResource).
SecureIdVerificationDocumentsContext refactored to hold
engine: TelegramEngine instead of raw postbox + network, drops
import Postbox (tally +1). The one instantiation site in
SecureIdDocumentFormControllerNode updates to pass
engine: self.context.engine.
Completes the last explicitly-named future-wave candidate from
CLAUDE.md.

Adds three thin forwarding methods on TelegramEngine.Resources
(fetch, status, data) over MediaBox, then migrates SaveToCameraRoll's
three public functions to use them, drops import Postbox from the
module (source + Bazel dep), and updates all 23 call sites across 14
caller files atomically.
Bundled: spec + fix + plan + C1 facades + C2 SaveToCameraRoll rewrite
+ BUILD dep drop + CLAUDE.md outcome.

Introduces a pin-to-edge mode for list items: items whose
pinToEdgeWithInset flag is true are pinned to the bottom edge of the
visible area, with the list geometry (pin inset, scrollToItem,
inset-transition offsetFix, visible-size updates) adjusted to handle
this new mode consistently.
Collected from spec, plan, and 12 iterative fixes during
implementation that refined pin-inset helpers, scroll landings, and
transition math. Pin-inset computation uses frame.size.height;
scrollToItem lands on the item's pinned position via apparentBounds.

Drive raw `MediaResource` out of the `TelegramEngine` public facade for
photo-upload APIs, and complete a first batch of consumer-side
migrations. Behavior-preserving. The `_internal_*` Postbox-facing
functions are untouched — only the facade signatures change, bridging
inside via `_asResource()` / `EngineMediaResource(_:)`.
TelegramEngine facades migrated (signatures now take EngineMediaResource):
- TelegramEngine.Peers.uploadedPeerPhoto / uploadedPeerVideo
- TelegramEngine.Peers.updatePeerPhoto (closure param too)
- TelegramEngine.AccountData.updateAccountPhoto / updateFallbackPhoto
- TelegramEngine.Contacts.updateContactPhoto
- TelegramEngine.Auth.uploadedPeerVideo
Consumer-side changes:
- MapResourceToAvatarSizes utility: signature is now
(engine: TelegramEngine, resource: EngineMediaResource, ...). Uses
engine.resources.data(id:) internally. The submodule drops
`import Postbox` and the Bazel dep.
- AuthorizationUI: avatar-video signal retyped from
Signal<TelegramMediaResource?> to Signal<EngineMediaResource?>.
- 27 `mapResourceToAvatarSizes(postbox:...)` call sites across 5
TelegramUI/TelegramCallsUI files migrated to the new form.
Deferred:
- SaveToCameraRoll (planned Task 8) abandoned — module has three
public functions taking `postbox: Postbox` (umbrella-type leak,
banned by rule 2) and requires a full module-migration wave, not a
type swap. Reason recorded in the wave-2 plan doc.
- Other TelegramEngine facades still leaking MediaResource
(TelegramEngineStickers.uploadSticker; UploadSecureIdFile.* —
additionally leaks Postbox) flagged for a future wave.
Docs:
- CLAUDE.md: new rule 7 (TelegramCore never imports UIKit/Display,
shared with Telegram-Mac), and a new "MediaResource →
EngineMediaResource consumer migration" section describing the
wrap/unwrap helpers and the modify-in-place facade-bridging
pattern.

Drop direct `import Postbox` from four leaf consumer submodules, routing
data access through TelegramEngine/TelegramCore. Behavior-preserving.
Consumers migrated:
- ChatInterfaceState
- ChatSendMessageActionUI
- ContactListUI
- DrawingUI
TelegramCore additions (typealiases + one EngineData item):
- EngineMemoryBuffer, EnginePostboxDecoder, EnginePostboxEncoder,
EngineAdaptedPostboxDecoder (narrow utility aliases for coding support)
- EngineData.Item.Configuration.ContactsSettings
Six planned modules were abandoned in wave 1 with reasons recorded in
the plan: ActionSheetPeerItem, ChatListSearchRecentPeersNode,
DirectMediaImageCache, FetchManagerImpl, GalleryData, ICloudResources.
Each either has a public API that leaks `Postbox`/`Account`/`MediaBox`
(banned umbrella-type aliases) or cascades into out-of-wave modules.
CLAUDE.md now records the wave rules, typealias cheat sheet, and the
wave-selection guidance learned from this pass.

TelegramCore does not re-export Postbox, so dropping the Postbox

typealias. Spell this out, and clarify that new typealiases are in
