Release: 5.2.1-rc0

A mode's own drain-rate bucket starts empty until it accumulates history,
so toggling ANC into an unlearned mode fell straight through to Apple's
optimistic spec rating while the mode just left showed its worse measured
rate. Result: enabling ANC could make the displayed time jump up ~1h.

Fill an empty ANC bucket at display time with the less-optimistic of the
mode-agnostic UNKNOWN reading and a sibling mode's learned rate, scaled by
the ratio of the two modes' rated drain. Scoped to spec'd models and
device-supported modes; picks the best-evidenced sibling, tie-broken by
closest rated drain then recency. No persistence or UI change.

The existing spec ceiling and display clamp still backstop the borrowed rate.

 ## Key Components
 
-### PodMonitor System
+### Device Monitoring
 
-- `PodMonitor`: Core service that detects and tracks AirPods via Bluetooth LE
-- `MonitorControl`: Manages MonitorService lifecycle
-- `MonitorService`: Foreground service that continuously scans for AirPods
-- `BluetoothEventReceiver`: Handles system Bluetooth events
+`monitor/core/` is split into two data-source siblings that `DeviceMonitor` merges:
+
+- `monitor/core/ble/BlePodMonitor` — passive BLE scanning; reads Apple advertisement beacons (battery, case state, in-ear, etc.). Works for any pod in range; no pairing required
+- `monitor/core/aap/` — AAP connection lifecycle layer on top of `AapConnectionManager`:
+  - `AapLifecycleManager` — starts/stops the AAP subsystem
+  - `AapAutoConnect` — auto-opens AAP sessions for bonded/known devices
+  - `AapKeyPersister`, `AapLearnedSettingsPersister` — persist session keys and learned pod settings across app restarts
+  - `StemConfigSender`, `StemPressReaction`, `AncGestureResolver` — push config and react to stem/HID events
+- `monitor/core/cache/DeviceStateCache` — persisted last-known state so profiles still show data when a device is out of range
+- `DeviceMonitor` — singleton that `combine`s `BlePodMonitor.devices + AapConnectionManager.allStates + DeviceStateCache + profiles` into unified `PodDevice` objects. ViewModels observe `DeviceMonitor.devices`; they do **not** reach into `BlePodMonitor` or the AAP layer directly
+- `MonitorControl` / `MonitorService` — foreground service lifecycle holding the scan awake
+- `BluetoothEventReceiver`, `BootCompletedReceiver` — system triggers that wake the service
+
+**BLE vs AAP — what each path gives you:**
+
+| | BLE (advertisements) | AAP (L2CAP session) |
+|---|---|---|
+| Direction | Read-only, passive | Bidirectional commands + events |
+| Prerequisite | Bluetooth on | Bonded + `BLUETOOTH_CONNECT` + active L2CAP socket |
+| Data | Battery, case open, in-ear, pod model | Settings, ANC mode control, press controls, stem events, device info |
+| Availability | Any pod in range | Only your own paired pods |
 
 ### Reaction System
 
-- `ReactionSettingsFragment`: Configuration for popup notifications
+- `ReactionsCard`: Compose UI for reaction settings, embedded in the device settings screen
 - `PopUpWindow`: Displays AirPods status when case is opened
-- `PopUpPodViewFactory`: Creates UI components for different pod models
+- `PopUpContent`: Compose pod rendering — model-specific UI branches inline, no factory class
+
+### Widget System (Glance)
+
+- `BatteryGlanceWidget`, `AncGlanceWidget`: Jetpack Glance-based home-screen widgets
+- `WidgetConfigurationActivity`: Configuration UI launched on widget placement
+- Lives under `app/src/main/java/eu/darken/capod/main/ui/widget/`
+
+### Upgrade / Pro Features
+
+- `UpgradeRepo` interface with two flavor implementations:
+  - `UpgradeRepoGplay` — billing-client backed, includes grace-period handling for interrupted purchases
+  - `UpgradeControlFoss` — cache/sponsor-backed; users are `isPro = false` until they call `upgrade()`, after which the pro flag is persisted via DataStore
+- FOSS is **not** "always pro" — it's opt-in via a local sponsor flow
+
+### AAP (Apple Accessory Protocol) Stack
+
+Three-layer structure under `pods/core/apple/aap/`:
+
+- **`protocol/`** — pure data: `AapMessage`, `AapCommand`, `AapSetting`, `AapDeviceProfile`, `AapDeviceInfo`, `StemPressEvent`, `KeyExchangeResult`. Plus `DefaultAapDeviceProfile` and `Model.Features` capturing per-model capability
+- **`engine/`** — session state machine for one connection:
+  - `AapConnection` — the L2CAP socket wrapper
+  - `AapSessionEngine` — drives the session lifecycle; tested in `AapSessionEngineTest`
+  - `AapInboundInterpreter` / `AapOutboundController` — decode incoming messages, encode outgoing
+  - `AapSettingsCoordinator`, `AapAncController`, `HidTracker`, `AapDeviceInfoDiagnostics` — feature-specific coordinators that sit on top of the session
+- **`AapConnectionManager`** (singleton) — owns all open AAP sessions keyed by `BluetoothAddress`, uses `L2capSocketFactory` to create sockets. Consumers don't touch `AapConnection` directly — they call `sendCommand(...)` and observe `allStates`
+
+The monitor-layer glue (`monitor/core/aap/`) described above wires this stack into the foreground service and persists its learned state.
 
 ### Common Utilities
 
@@ -54,31 +104,20 @@ globs:
 
 ## Data Flow
 
-The app follows a unidirectional data flow:
-
-1. `BluetoothEventReceiver` detects Bluetooth events
-2. `MonitorService` scans for AirPods beacon data
-3. `PodMonitor` processes and stores device information
-4. ViewModels observe monitor data via repositories
-5. UI components react to ViewModel state changes
-6. `ReactionSystem` triggers popups and notifications
-
-## Bluetooth LE Implementation
-
-The app uses Android's Bluetooth LE APIs to scan for Apple device advertisements. The core scanning logic is in `MonitorService` which runs as a foreground service.
-
-## Multi-Platform Considerations
-
-Code shared between phone and Wear OS apps is placed in `app-common`. When modifying shared functionality, ensure compatibility across both platforms.
+1. `BluetoothEventReceiver` / `BootCompletedReceiver` wake `MonitorService` (foreground)
+2. `MonitorService` keeps `BlePodMonitor` scanning (passive advertisements) and `AapLifecycleManager` running (active L2CAP sessions via `AapConnectionManager`)
+3. `DeviceMonitor` merges BLE + AAP + cached state + profiles into `PodDevice` objects
+4. ViewModels (`OverviewViewModel`, `DeviceSettingsViewModel`, `PressControlsViewModel`, widget view models) observe `DeviceMonitor.devices`; settings/command changes are sent back through `AapConnectionManager.sendCommand(...)`
+5. Reaction triggers (case-open popup, auto-play, notifications) and widget state updates react to the merged flow
 
 ## Testing Strategy
 
-- **Unit Tests**: Located in `app-common/src/test/` for shared logic
-- **Test Flavors**: Separate test configurations for FOSS and Google Play variants
+- **Unit Tests**: `app/src/test/` (shared), `app/src/testFoss/`, `app/src/testGplay/` (flavor-specific — e.g. `UpgradeRepoGplayTest`, `FossUpgradeSerializationTest`)
+- **Screenshot Tests**: `app/src/screenshotTest/` — Compose Preview Screenshot Testing, powers the Play Store screenshot pipeline
 
 ## Key Dependencies
 
 - **Hilt**: Dependency injection framework
-- **AndroidX Navigation**: Fragment navigation with SafeArgs
+- **Navigation**: Navigation3 (`addNavigation3()`) drives current Compose screen routing. Some legacy `androidx.navigation` helpers still exist (`NavDirectionsExtensions`, `ViewModel3`) — don't assume SafeArgs is fully gone
 - **kotlinx.serialization**: JSON serialization for configuration and caching
-- **Material Design**: UI components following Material Design guidelines
+- **Material Design 3**: Compose Material3 UI components

+# Release Process
+
+Releases are cut via the **Release prepare** workflow (`.github/workflows/release-prepare.yml`). It bumps `version.properties` and `VERSION`, commits to `main`, tags `v<version>`, pushes atomically, and dispatches `release-tag.yml` which builds, signs, and uploads.
+
+## Dispatch
+
+```bash
+# Plan only — no commit, no tag, no push.
+gh workflow run release-prepare.yml -f bump_kind=build -f dry_run=true
+
+# Real cut.
+gh workflow run release-prepare.yml -f bump_kind=build -f dry_run=false
+```
+
+After `dry_run=false`: Job 1 computes + writes the summary, then Job 2 immediately commits/tags/pushes (no env gate — cancel the run between Job 1 and Job 2 if the summary looks wrong; you have ~seconds). The tag push naturally triggers `release-tag.yml` (the App-token push fires `on: push:` workflows; only `GITHUB_TOKEN`-pushes are suppressed). `release-tag.yml` then runs `validate-tag` and the existing `release-github` (`foss-production` approval) + `release-gplay` (`gplay-production` approval) jobs — those are the two human checkpoints, matching the pre-migration UX.
+
+## Inputs
+
+| Input | Default | Notes |
+|---|---|---|
+| `bump_kind` | `build` | `build` \| `patch` \| `minor` \| `major` |
+| `version_type` | `keep-current` | Preserves current `rc`/`beta`. Set explicitly to switch. |
+| `version_override` | empty | e.g. `5.1.2-rc0`. Bypasses bump_kind/version_type. |
+| `expected_current` | empty | Optional: fail if `version.properties` ≠ this. Useful for tight coordination. |
+| `dry_run` | `true` | Default is plan-only. |
+
+Bump rules: `build` increments build; `patch`/`minor`/`major` zero everything to the right of the bumped field. All numeric fields bounded `0..99` (the `versionCode` formula collapses at ≥100).
+
+## Local
+
+```bash
+./tools/release/bump.sh --mode=plan --bump-kind=build --version-type=keep-current
+./tools/release/bump.sh --mode=check
+bats tools/release/bump.bats
+```
+
+## Channel mapping
+
+| Tag suffix | FOSS APK | GitHub release | Fastlane lane | Play track | Rollout |
+|---|---|---|---|---|---|
+| `-beta*` | `assembleFossBeta` | pre-release | `beta` | `beta` | 10% |
+| `-rc*` (or anything else) | `assembleFossRelease` | full release | `production` | **`beta`** | 10% |
+
+`lane :production` in `Fastfile` uploads to Play's **beta** track at 10% — manually promoted to production via Play Console.
+
+## Rollback
+
+| Stage reached | Steps |
+|---|---|
+| Bump on `main`, downstream not started | `git push origin :refs/tags/v<bad>`, `git revert <bump-sha>`, push |
+| GitHub release created | Above + `gh release delete v<bad> --yes --cleanup-tag` |
+| Play upload completed | Above + halt rollout in Play Console (or `bundle exec fastlane supply --track beta --rollout 0 --version-code <bad-code>`) |
+| Job 2 ran but downstream rejected at env approval | Treat as first row — bump+tag are public on `main` regardless of downstream outcome |
+
+`bump.sh` enforces strict `versionCode` monotonicity, so re-using a code is impossible without manually editing `version.properties`.
+
+## Auth setup
+
+`release-prepare.yml` Job 2 uses a GitHub App token (not `GITHUB_TOKEN`) to push the bump commit and tag. The App identity is in the rulesets' bypass list, which is what allows the push to bypass branch protection + tag-creation restrictions.
+
+Required org secrets (set on the d4rken-org organization, accessible to `capod`):
+
+- `RELEASE_APP_CLIENT_ID` — Client ID of the `d4rken-org-releaser` GitHub App (visible on the App's settings page, format `Iv1.<hex>` or similar)
+- `RELEASE_APP_PRIVATE_KEY` — full `.pem` contents (including BEGIN/END lines)
+
+The App is installed on this repo and added as a bypass actor to:
+- The main-branch ruleset (PR + status check requirements)
+- The tag ruleset (creation restriction on `v*`)
+
+Other apps in the org can reuse the same App + secrets — just install the App on each repo and add it to that repo's rulesets' bypass lists.
+
+## Defense in depth
+
+`release-tag.yml` includes `validate-tag` which: (1) regex-checks `github.ref_name`, (2) runs `bump.sh --mode=check`, (3) asserts the parsed name matches the tag. Manual `gh workflow run release-tag.yml --ref vfoo` or hand-pushed tags fail before any build.
+
+## Stuck-dispatch recovery
+
+If Job 2's atomic push lands but the natural `on: push:` trigger doesn't fire `release-tag.yml` (rare — would mean GitHub dropped the event), the tag is public but no pipeline runs. Re-dispatch manually: `gh workflow run release-tag.yml --ref v<new> -f dry_run=false`.

-- Batch size defaults to 2 locales (16 renders) to avoid layoutlib memory leak (~10MB/image)
+- Batch size defaults to 2 locales; renders per batch = `BATCH_SIZE × screen count` (currently 2 × 7 = 14). Small batches avoid layoutlib memory leaks (~10MB/image)
