Pingogram v0.1.0

Added

• Project scaffold, documentation, CI, TDLib and release workflows.

• Gradle project: version catalog, build-logic convention plugins, Gradle 9.8.1 wrapper and the
  :app, :core:* and :feature:* modules from docs/ARCHITECTURE.md (mostly empty for now).
  AGP 9.4.1, Kotlin 2.4.21, Compose BOM 2026.09.00; foss/gms flavors; app version and
  per-ABI version codes from -Pversion.

• Telegram API credentials come from the git-ignored secrets.properties; the build fails with a
  clear message (never echoing values) when the file or a key is missing or malformed.

• Committed debug keystore for consistent debug signatures; release signing from environment or
  keystore.properties (v2/v3/v4), and release packaging fails early when signing is not configured.

• Static analysis in ./gradlew check: ktlint 1.8 (./gradlew ktlintFormat), detekt 1.23.8 with the
  PingogramHardcodedToken rule (no literal colors, text sizes, sizes, shapes or animation specs in
  :feature:* code), Android Lint with warnings as errors, and ./gradlew dependencyUpdates.

• :benchmark module: Macrobenchmark StartupBenchmark and Baseline/Startup Profile generation
  (./gradlew :app:generateBaselineProfile); release builds ship the profile via profileinstaller.

• PingogramTheme on MaterialExpressiveTheme: six generated brand color schemes (seed #E8457C,
  standard/medium/high contrast), dynamic color on Android 12+, system contrast on Android 14+,
  AMOLED black, harmonized online green; the full Google Sans Flex type scale (15 styles + 15
  emphasized, per-style variable axes); the expressive shape scale with MaterialShapes helpers;
  spacing tokens; preview helpers; splash and window themes.

• Roborazzi screenshot tests (Robolectric, native graphics) verified by ./gradlew check.

• Release builds produce one APK per ABI (arm64-v8a, armeabi-v7a, x86_64) plus a universal APK,
  with distinct version codes. Native code for other ABIs is left out, so devices that only support
  32-bit x86 cannot install the app.

• TDLib 1.8.68 for Android, built by the Build TDLib workflow and published as the tdlib-a94b83d67a
  release; the build downloads it and verifies its pinned SHA-256 (pingogram.tdlib.aar overrides it with
  a local AAR).

• core:tdlib: coroutine TdlibClient with typed authorization and connection state, automatic
  SetTdlibParameters (honest client identification), database key wrapped by the Android Keystore and
  kept out of backups; FakeTdlibClient and TdApi fixtures for tests.

• App shell: MainActivity (splash, edge-to-edge, predictive back) with type-safe navigation and an
  adaptive NavigationSuiteScaffold — short navigation bar on phones, navigation rail on larger
  screens — with Chats, Contacts and Settings placeholder tabs and Material Symbols Rounded icons.

• Sign-in flow (feature:auth): welcome, phone number with country picker and live formatting, login
  codes of every type with resend countdown, two-step verification password with recovery by email,
  registration with terms of service, QR code login, email address and email code, and an explanation when
  an account needs Telegram Premium to sign in (no purchase flow). Rate limits show a countdown and an
  offline banner appears while there is no connection; errors map to readable messages.

• The app opens on the sign-in flow when logged out and on the chats when logged in; the splash screen
  waits up to 300 ms for TDLib. Logging out (Settings → Log out, with confirmation), being logged out
  elsewhere, or a closed session returns to sign-in with nothing of the previous account left behind.

• Sign-in screens polished: real QR code for QR login (ZXing), password visibility toggle, adaptive layout
  for tablets, landscape and large fonts, shared-axis transitions and predictive back between steps,
  screen-reader friendly countdowns and banners; screenshot tests for every step in light, dark and
  dynamic color.

Changed

• Package root and applicationId are dev.kyralabs.pingogram (debug: dev.kyralabs.pingogram.debug).
• compileSdk is 37 (needed by Compose 1.12); targetSdk stays 36.
• Uses the pre-release androidx.compose.material3:material3:1.5.0-beta01 (allowed by CLAUDE.md rule 7):
  in the stable 1.4.0 the Material 3 Expressive APIs (MotionScheme.expressive(), MaterialShapes,
  the emphasized type styles, the increased shape sizes) are internal.
• Backups and device transfer are disabled for all app data.

Downloads

• universal — works on every device (largest)
• arm64-v8a — most phones from 2017 onwards
• armeabi-v7a — older 32-bit devices
• x86_64 — emulators / Chromebooks
