# Releasing Sauci Mobile App

This guide covers local release builds for Android and iOS.

JavaScript-only changes can also ship over the air between store releases. See
[Mobile over-the-air updates](mobile-ota.md). Anything that changes native code
still requires a store build with a bumped `expo.version`, because the OTA
explicit runtime version is synchronized with the app version.

## Prerequisites

- **Java JDK 17** - Required for Android Gradle builds
- **Android Studio** - For SDK and build tools (including Android SDK/NDK)
- **Xcode** - For iOS builds (macOS only)
- **EAS CLI** - `npm install -g eas-cli`
- **Expo account** - Run `eas login` to authenticate

---

## EAS Build Local (Recommended)

The `--local` flag runs the EAS build process on your machine instead of Expo's cloud servers. This automatically handles signing credentials and produces the same output as cloud builds.

### Quick Start

```bash
cd apps/mobile

# Android - produces .aab file (for Play Store)
npm run release:android

# iOS - produces .ipa file (for App Store)
npm run release:ios
```

Output files are placed in the current directory by default.

These scripts create signed artifacts only. They do not upload or submit them.
An explicit request for a mobile release, upload, or store-submission workflow
authorizes the requested store upload within its stated platform and destination
scope. Building an artifact alone does not authorize an upload.

Before every production build, run the deterministic source gate:

```bash
cd apps/mobile
npm run release:preflight
```

It checks public and OTA runtime version parity, iOS app/widget build parity,
and that the public OTA certificate is tracked and not excluded by root archive
rules. It does not replace inspection of the exported artifact.

## Submit a local artifact with EAS

The production submission credentials are managed by EAS. Never add App Store
Connect `.p8` files, Google service-account JSON files, or local credential paths
to the repository or `eas.json`.

Submit only an independently verified artifact by its exact absolute path:

```bash
cd apps/mobile

# Uploads an Android internal-track draft; it does not roll out the release.
eas submit --platform android --profile production --path /absolute/path/to/sauci.aab --wait

# Uploads to App Store Connect/TestFlight; it does not submit for App Review.
eas submit --platform ios --profile production --path /absolute/path/to/sauci.ipa --wait
```

Agents must not upload an unverified artifact, whether they use EAS, Fastlane,
Xcode Organizer, or a store console. Before upload, they must verify and report
the platform, exact path, bundle/package identifier, version, build number,
signing identity, SHA-256 digest, and destination. Once those details match the
user's stated scope, proceed without asking for a second confirmation.

Before an iOS upload, inspect App Store Connect for automatic TestFlight
distribution. If upload will add the build to existing groups or testers, report
them before proceeding. If the effect cannot be established, stop. Changing
automatic-distribution settings is a separate action and requires its own
authorization.

App Store Connect API group association alone does not reveal whether automatic
distribution is enabled. Verify the switch in an authenticated App Store Connect
UI session before upload. If the UI cannot be checked, stop instead of
inferring the effect from API data.

Do not use `--latest` for a local release. Before upload, verify the artifact's
package or bundle identifier, public version, build number, signature, and
SHA-256 digest. After upload, read back the same identity and version from Google
Play Console or App Store Connect. Public rollout, App Review submission, and
additional TestFlight group distribution remain separate, explicitly authorized
actions unless the original request expressly includes them. If an upload command
returns an ambiguous result, inspect EAS and the store first; do not retry unless
the user explicitly authorizes another upload.

### Source integrity

Sauci commits its native `ios/` and `android/` projects. Start a release from a
clean worktree whose `HEAD` matches its fetched upstream, and do not run
`expo prebuild` before a routine release build. EAS detects the native projects
and packages the checked-in sources directly.

After the build, inspect `git diff`. Only the expected local EAS version fields
may change: `app.json`, the platform native version file, and the iOS widget
`Info.plist` for an iOS build. Any widget implementation, resource, or Xcode
project rewrite means the source was regenerated and the artifact must be rebuilt
from the clean tracked sources.

Accept an artifact only after independent inspection. Verify Android package,
version, signer, all four ABIs, required Worklets/Reanimated/Skia libraries,
forbidden media-read permissions, OTA runtime/channel/certificate, and SHA-256.
Verify the iOS IPA's app and every extension version/build/signature after export.
Quarantine or remove a rejected artifact before presenting any artifact for
upload. Tag the exact verified build-source commit, then promote it through
staging and main only after the release gates pass.

The committed Android Gradle ordering fix makes Prefab inputs available before
dependent native tasks. Preserve that explicit dependency ordering. Do not try to
solve Gradle task validation by removing Firebase or cycling dependency versions.

After Android upload, EAS Submit `FINISHED`, the exact internal/DRAFT/no-rollout
submit configuration, and the retained artifact digest are the authoritative
available read-back when direct Play track inspection would require creating an
edit. Never create an edit merely to claim read-only verification.

### Android media permission policy

Sauci uses the Android system photo picker for user-selected images and videos.
Android release manifests must not contain `READ_MEDIA_IMAGES` or
`READ_MEDIA_VIDEO`. Gallery save flows request add-only access and must not add
broad read access. After any Expo, media-library, image-picker, or native Android
change, run `:app:processReleaseMainManifest` and inspect the merged release
manifest before building an artifact for Google Play.

### Building an APK (for Testing)

The production profile creates an AAB (Android App Bundle), which can't be directly installed on devices. To build an APK for testing:

```bash
# Use the preview profile (configured for APK output)
eas build --platform android --profile preview --local
```

Or add a custom profile to `eas.json`:

```json
{
  "build": {
    "local-apk": {
      "android": {
        "buildType": "apk"
      }
    }
  }
}
```

Then run:
```bash
eas build --platform android --profile local-apk --local
```

### Installing the APK

```bash
# Via ADB (device connected via USB)
adb install ./build-*.apk

# Or drag-and-drop onto Android Emulator
```

### Build Profiles

| Profile | Output | Use Case |
|---------|--------|----------|
| `production` | .aab | Play Store / App Store submission |
| `preview` | .apk | Internal testing, device installation |
| `development` | .apk | Dev client with hot reload |

### Environment Variables

Useful for debugging build issues:

| Variable | Purpose |
|----------|---------|
| `EAS_LOCAL_BUILD_SKIP_CLEANUP=1` | Keep build directory after completion |
| `EAS_LOCAL_BUILD_WORKINGDIR=/path` | Custom build directory (default: /tmp) |
| `EAS_LOCAL_BUILD_ARTIFACTS_DIR=/path` | Output directory for build artifacts |

Example with debugging enabled:
```bash
EAS_LOCAL_BUILD_SKIP_CLEANUP=1 \
EAS_LOCAL_BUILD_WORKINGDIR=~/eas-builds \
eas build --platform android --profile production --local
```

For local builds, choose stable ignored working and artifact directories and
retain them with the command log until the artifact is accepted or rejected.
Check free disk space first. `ENOSPC`, EAS plugin startup, archive construction,
and dependency installation failures occur before native compilation: fix and
preflight those inputs without starting another build. Make one meaningful build
per newly proven input state.

Report provider progress by phase: packaging, native compilation, submission
queue, or store processing. Do not describe every failure as a rebuild.

If the normal EAS invocation cannot find its local-build plugin, use a matching
CLI and plugin version and set `EAS_LOCAL_BUILD_PLUGIN_PATH` to that plugin's
executable `bin/run`, not its package directory. Do not commit or document a
machine-specific package-cache path. Run `npm run release:preflight:local-eas`
after setting the variable. See https://docs.expo.dev/build-reference/local-builds/
and https://github.com/expo/eas-cli/issues/2787.

### Limitations of Local Builds

- **Single platform only** - Can't use `--platform all`
- **Software versions ignored** - `node`, `yarn`, `ndk`, `image` fields in eas.json are ignored
- **No caching** - Each build starts fresh
- **Secret env vars not available** - Set them in your local environment instead
- **macOS/Linux only** - Windows requires WSL (unsupported)

### Troubleshooting Local Builds

**Java version mismatch:**
```bash
# Check Java version (should be 17)
java -version

# On macOS, switch Java version
export JAVA_HOME=$(/usr/libexec/java_home -v 17)
```

**Gradle daemon issues:**
```bash
cd android && ./gradlew --stop && cd ..
```

**Native regeneration after dependency changes:**

Treat `expo prebuild` as a source change, not a release step. Run it separately
only when native dependencies intentionally changed, review the full native diff,
verify it, and commit it before starting the release from a clean worktree. Use
`expo prebuild --clean` (see `docs/mobile-ota.md`); as of `@bacons/apple-targets`
5.x, a non-clean prebuild against an already-generated iOS project fails while
updating the widget's Xcode target.

**Out of memory:**
```bash
# Increase Gradle memory
echo "org.gradle.jvmargs=-Xmx4g" >> android/gradle.properties
```

## Manual Android Release Build

### Step 1: Get the Production Keystore

The production keystore is stored in EAS. Download it:

```bash
cd apps/mobile
eas credentials --platform android
```

Select:
1. `production`
2. `Keystore`
3. `Download Keystore`

Save the keystore file and note the **password** and **alias** shown.

### Step 2: Configure Signing

Ensure `android/gradle.properties` has the keystore configuration:

```properties
MYAPP_UPLOAD_STORE_FILE=sauci-release.keystore
MYAPP_UPLOAD_KEY_ALIAS=<alias from EAS>
MYAPP_UPLOAD_STORE_PASSWORD=<password from EAS>
MYAPP_UPLOAD_KEY_PASSWORD=<password from EAS>
```

**Important:** Never commit these credentials to git.

### Step 3: Confirm tracked native sources

The committed `android/` project is the release source. If native dependencies
changed, regenerate and review that project as a separate change before release.

### Step 4: Build the Release Bundle

```bash
cd android
./gradlew bundleRelease
```

The AAB file will be at:
```
android/app/build/outputs/bundle/release/app-release.aab
```

### Step 5: Upload to Play Store

Apply the upload execution policy above before opening or changing the release.
Uploading the AAB and starting any rollout are separate actions unless the
original request expressly includes the rollout.

1. Go to [Google Play Console](https://play.google.com/console)
2. Select **Sauci** app
3. Go to **Internal testing**, unless the user authorized a different exact track
4. **Create new release**
5. Upload the `.aab` file
6. Add release notes, save the release as a draft, and read it back

Do not send the draft for review or start a rollout unless the original request
expressly includes that action.

### Verifying Keystore Fingerprint

To verify you're using the correct keystore:

```bash
keytool -list -v -keystore android/sauci-release.keystore -storepass <password>
```

Expected EAS production upload-key SHA1: `F0:60:26:C7:54:B0:46:F2:80:FE:AC:43:8A:69:10:BD:9A:62:B4:59`

---

## iOS Release Build

### Step 1: Confirm tracked native sources

The committed `ios/` project is the release source. If native dependencies
changed, regenerate and review that project as a separate change before release.

### Step 2: Install Pods

```bash
cd ios
pod install
cd ..
```

### Step 3: Build Archive in Xcode

1. Open `ios/Sauci.xcworkspace` in Xcode
2. Select **Any iOS Device (arm64)** as the build target
3. Go to **Product** → **Archive**
4. Wait for the build to complete

### Step 4: Upload to App Store

Apply the upload execution policy above before using Xcode Organizer. Report any
verified automatic TestFlight distribution before uploading.

1. In Xcode Organizer (Window → Organizer), select the archive
2. Click **Distribute App**
3. Select **App Store Connect** → **Upload**
4. Follow the prompts to upload

### Step 5: Submit in App Store Connect

Submitting for App Review is not authorized by an upload request unless the
original request expressly includes App Review submission.

1. Go to [App Store Connect](https://appstoreconnect.apple.com)
2. Select **Sauci**
3. Create a new version or select the uploaded build
4. Fill in release notes and submit for review

---

## Version Management

Version is managed locally by EAS with `appVersionSource: "local"` in
`apps/mobile/eas.json`. Production builds auto-increment the platform build
number and synchronize the tracked native version file. For a public-version
bump, use the release version script rather than editing individual sources: it
updates and verifies `app.json`, the explicit Expo runtime string, and the
checked-in iOS and Android public/runtime values together.

```bash
node .codex/skills/generate-release/scripts/set_version.mjs --version 1.0.7
node .codex/skills/generate-release/scripts/set_version.mjs --check
```

To inspect or deliberately set versions:

```bash
# Check current version
eas build:version:get

# Set version manually
eas build:version:set --platform android --version 1.0.1
eas build:version:set --platform ios --version 1.0.1
```

The user-facing version remains in `app.json`:

```json
{
  "expo": {
    "version": "1.0.1"
  }
}
```

And for Android, update `android/app/build.gradle`:

```gradle
versionCode 2
versionName "1.0.1"
```

---

## Troubleshooting

### Wrong Keystore Error

If Play Store rejects with "signed with wrong key":

1. Run `eas credentials --platform android`
2. Download the correct keystore
3. Verify fingerprint matches expected SHA1
4. Replace your local keystore file

### Build Failures After Dependency Changes

```bash
# Clean the existing tracked Android project and rebuild it
cd android && ./gradlew clean && cd ..
cd android && ./gradlew bundleRelease
```

If native regeneration is genuinely required, do it as a separate reviewed and
committed source change before running the release build.

### iOS Signing Issues

Ensure your Apple Developer certificates and provisioning profiles are up to date in Xcode:
- **Xcode** → **Settings** → **Accounts** → Download Manual Profiles

For a checked-in entitlement, first read the corresponding Apple App ID
capability state. EAS capability sync can report success while Apple rejects a
malformed update, as tracked in https://github.com/expo/eas-cli/issues/3986.
Read back Associated Domains, regenerate only the affected profile, and decode
the replacement profile to confirm `com.apple.developer.associated-domains`
before rebuilding. With noninteractive managed App Store Connect key auth, set
`EXPO_APPLE_TEAM_ID` when the command cannot otherwise select the correct team.
Preserve existing certificates and unrelated target profiles.
