+- `TdClientTrait` теперь facade поверх scoped traits; чтение текущих сообщений идёт через `Cow`, mutation - через явные update-операции.

+# TeleTuiIOS
+
+Native SwiftUI shell for the iOS client.
+
+Current scope:
+
+- SwiftUI + MVVM app shell backed by a deterministic fake bridge.
+- Auth, chat list, folder selector, chat detail, compose bar, profile sheet, and account switcher shell.
+- iOS-oriented storage boundaries: Keychain-shaped credential API and Application Support account paths.
+
+Build and smoke-test the portable shell:
+
+```bash
+cd apps/ios/TeleTuiIOS
+swift run TeleTuiIOSSmokeTests
+```
+
+Verify local iOS tooling:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/check-ios-prereqs.sh
+```
+
+Build the SwiftUI shell for iOS Simulator and package it as an installable `.app`:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-simulator-app.sh
+```
+
+Launch the fake-backed app in the first available iPhone simulator:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/run-ios-simulator-app.sh
+```
+
+Run the simulator launch plus screenshot sanity check:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/smoke-ios-simulator-ui.sh
+```
+
+Build the app against the local real Rust/TDLib FFI artifacts:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-real-ffi-xcframework.sh
+TELE_IOS_USE_LOCAL_FFI=1 DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-simulator-app.sh

+# tele-ios-ffi
+
+UniFFI bridge for the future native iOS app.
+
+Current scope:
+
+- Exposes a fake-backed `SessionHandle` for Swift integration tests and app shell work.
+- Mirrors the `tele-core::session` DTO/event model with UniFFI-compatible records and enums.
+- Supports a fake-only build for UI work and a real TDLib build path using local iOS TDLib artifacts.
+
+Generate Swift bindings and headers:
+
+```bash
+scripts/generate-ios-ffi-bindings.sh
+```
+
+The script builds `target/release/libtele_ios_ffi.a` and writes Swift sources,
+headers, a Swift typecheck-friendly `tele_ios_ffiFFI` module map, and an
+XCFramework-compatible module map under `build/ios-ffi/`.
+
+Build the fake-only iOS simulator XCFramework without linking TDLib:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-fake-ffi-xcframework.sh
+```
+
+Run an executable Swift smoke test against matching fake-only UniFFI bindings:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/smoke-ios-ffi-swift.sh
+```
+
+Typecheck the Swift app bridge against generated UniFFI bindings:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/typecheck-ios-uniffi-app-bridge.sh
+```
+
+Current linking status:
+
+- Xcode is installed at `/Applications/Xcode.app`, and `DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer xcodebuild -version` reports Xcode 26.5.
+- The iOS 26.5 simulator runtime is installed and `scripts/check-ios-prereqs.sh` passes with available iPhone/iPad simulators.
+- The current app shell uses the fake Swift bridge.
+- `tdlib-rs` does not publish iOS `download-tdlib` archives, so real iOS linking uses `tele-core/tdlib-local` and `LOCAL_TDLIB_PATH`.
+- Local TDLib linking is validated for `aarch64-apple-ios-sim` via `scripts/check-ios-tdlib-linking.sh` and for `aarch64-apple-ios` via `IOS_RUST_TARGET=aarch64-apple-ios scripts/build-ios-ffi-with-local-tdlib.sh`.
+- `scripts/build-ios-real-ffi-xcframework.sh` packages local simulator Rust slices plus local `libtdjson` into app-local XCFrameworks, generates Swift bindings, and enables Xcode builds with `TELE_IOS_USE_LOCAL_FFI=1`.
