 ## [Unreleased]
 
+## [1.1.0] - 2026-05-25
+
+### Added
+- Hilt 2.56.2 DI: `@Singleton` repository, `@HiltViewModel` on all ViewModels, `AppModule`
+- 13 instrumented tests: `NoiseLevelDaoTest` (9) + `NavigationTest` (4)
+- GitHub Actions CI/CD with green badge — unit tests on every push
+- `HiltTestRunner`, `TestAppModule` (in-memory Room), `TestUtils` for test infrastructure
+
+### Fixed
+- Multiple-ViewModel buffer bug: three independent `NoiseRepositoryImpl` instances
+  caused clearing history while monitoring to silently fail
+- `ActivityInvoker` ClassNotFoundException on instrumented test teardown
+
+## [1.0.2] - 2026-05-24
+
+### Fixed
+- Permission flow: app now requests microphone and notification permissions
+  on first launch via system dialog (previously showed blocked screen immediately)
+- Microphone unavailable toast appeared incorrectly when tapping STOP MONITORING
+- Version number in Settings was hardcoded as 1.0.0 (now uses BuildConfig.VERSION_NAME)
+- Notifications toggle showed ON even when Android notification permission was OFF
+
+## [1.0.1] - 2026-05-23
+
+### Fixed
+- License updated from CC BY-NC to BUSL-1.1
+- README: Hilt added to tech stack, Accompanist version corrected, Android Studio
+  version updated to Meerkat (2025.1.1)
+- ARCHITECTURE.md: removed incorrect "No Hilt" section, replaced with actual DI setup
+- ADRs renumbered (clean sequence), ADR-004 documents Hilt decision
+- Calibration offset corrected to 80 dB throughout docs

+82 tests total — 69 unit and 13 instrumented.
+
+Unit tests run on the JVM, no Android runtime needed. They cover noise
+classification, dB calculation, batch buffer logic, period filtering,
+and settings validation.
+
+Instrumented tests run on a physical device (the emulator mic returns
+~20 dB regardless of environment, which makes audio tests meaningless):
+- `NoiseLevelDaoTest` — 9 tests against an in-memory Room database
+- `NavigationTest` — 4 tests verifying the bottom nav flow
+
+Infrastructure: `HiltTestRunner` swaps the app component for a test
+component; `TestAppModule` provides the in-memory DB; `TestUtils` keeps
+timestamps deterministic.

 The singleton scope matters: without it, each ViewModel constructs its own `NoiseRepositoryImpl`, which means three independent write buffers. Clearing history while monitoring was broken until this was fixed. See [ADR-004](ADRs.md#adr-004-hilt-for-dependency-injection) for the full reasoning.
 
 No multi-module, no WorkManager — neither is warranted at this scale.

+## Testing
+
+**Unit tests (69)** run on the JVM — no Android runtime, no emulator needed.
+`AudioAnalyzer`, `NoiseRepository`, and ViewModel logic are covered.
+
+**Instrumented tests (13)** run on a physical device:
+- `NoiseLevelDaoTest` — Room DAO queries against an in-memory database
+- `NavigationTest` — Compose navigation via `createAndroidComposeRule<MainActivity>()`
+
+Test infrastructure:
+- `HiltTestRunner` — replaces the default runner, swaps Hilt component for test component
+- `TestAppModule` — provides in-memory Room DB, isolates tests from on-device data
+- `TestUtils` — fixed `BASE_TIMESTAMP` and helpers for deterministic test data
