+# Google Play Release Runbook
+
+## Purpose
+
+This runbook prepares and ships the Android release build for `com.meshcore.sar.meshcore_sar_app`.
+
+## Distribution Modes
+
+- GitHub release: signed APK for direct install or manual distribution.
+- Google Play: signed AAB uploaded through Fastlane to Play internal testing and, for non-prerelease GitHub releases, production.
+
+## Required Secrets and Local Files
+
+GitHub Actions secrets for `dz0ny/meshcore-sar`:
+
+- `ANDROID_KEYSTORE_BASE64`
+- `ANDROID_KEYSTORE_PASSWORD`
+- `ANDROID_KEY_ALIAS`
+- `ANDROID_KEY_PASSWORD`
+- `GOOGLE_PLAY_SERVICE_ACCOUNT_JSON`
+
+Local files used to seed the secrets:
+
+- `android/key.properties`
+- release keystore referenced by `android/key.properties`
+- `/Users/dz0ny/android-keystores/fastlane-480919-0cb30c62db50.json`
+
+The Play Console service account must have release access for `com.meshcore.sar.meshcore_sar_app`.
+
+## CI Release Flow
+
+The release flow runs from `.github/workflows/build-artifacts.yml` when a GitHub release is published.
+
+Android release steps:
+
+1. Validate all Android signing and Google Play secrets.
+2. Recreate `android/release-keystore.jks` and `android/key.properties` from GitHub secrets.
+3. Build the signed APK with `flutter build apk --release`.
+4. Build the signed Play AAB with `flutter build appbundle --release`.
+5. Upload the APK and AAB as GitHub release assets.
+6. Upload the AAB to Play internal testing with `bundle exec fastlane android internal`.
+7. Upload the AAB to Play production when the GitHub release is not marked as prerelease.
+
+The same workflow also builds Linux, macOS, Windows, iOS unsigned, and web artifacts.
+
+## Versioning Rules
+
+- Version source of truth: `pubspec.yaml`.
+- Android `versionCode` is the number after `+`.
+- `versionCode` must always increase for Play uploads.
+- `make bump`, `make build`, and `make bundle` increment the version.
+- Use `make build-no-bump` or `make bundle-no-bump` only when intentionally rebuilding the same version locally.
+
+## Manual Build Commands
+
+Run commands from the repo root.
+
+```bash
+flutter build apk --release
+flutter build appbundle --release
+```
+
+Repo shortcuts:
+
+```bash
+make build
+make bundle
+make build-no-bump
+make bundle-no-bump
+```
+
+## Fastlane Lanes
+
+Run commands from `android/`.
+
+```bash
+bundle exec fastlane android direct_apk
+bundle exec fastlane android internal
+bundle exec fastlane android production
+```
+
+Set `SKIP_ANDROID_BUILD=1` when an AAB has already been built and Fastlane should only upload it.
+
+```bash
+SKIP_ANDROID_BUILD=1 GOOGLE_PLAY_SERVICE_ACCOUNT_JSON="$(cat /Users/dz0ny/android-keystores/fastlane-480919-0cb30c62db50.json)" bundle exec fastlane android internal
+```
+
+## Expected Artifacts
+
+- APK: `build/app/outputs/flutter-apk/app-release.apk`
+- AAB: `build/app/outputs/bundle/release/app-release.aab`
+- Release APK asset: `meshcore-sar-<tag>-android.apk`
+- Release AAB asset: `meshcore-sar-<tag>-play.aab`
+
+## Internal Testing Release Checklist
+
+1. Confirm `pubspec.yaml` version is correct and `versionCode` increased.
+2. Confirm `android/key.properties` points to the release keystore for local builds.
+3. Confirm all five GitHub Actions secrets exist.
+4. Publish a prerelease in GitHub to build assets and upload Play internal testing without production promotion.
+5. Install from the internal testing track on a real Android device.
+6. Smoke test startup, permissions, map, messaging, telemetry, and offline map behavior.
+
+## Production Release Checklist
+
+1. Complete internal testing validation first.
+2. Confirm Play Console forms are current:
+   - App content
+   - Data safety
+   - App access
+   - Ads declaration
+   - Content rating
+3. Confirm store assets are current:
+   - app icon
+   - feature graphic
+   - phone screenshots
+   - tablet screenshots if used
+   - support URL
+   - privacy policy URL
+4. Publish a non-prerelease GitHub release.
+5. Confirm the GitHub release has the APK and AAB assets.
+6. Confirm Play Console has the new internal and production release entries.
+
+## Rollback Rules

+# Swarm Mode Technical Design
+
+## 1. Overview
+
+Swarm mode is a shared media-recovery transport used by both voice and image
+sessions when the original sender path stops responding after some fragments
+have already propagated through the mesh.
+
+It adds a lightweight **swarm discovery plane** on top of the existing
+**direct raw-data transfer plane**:
+
+- **Discovery plane (raw custom control payloads):**
+  - `MediaSwarmRequest`
+  - `MediaSwarmAvailability`
+- **Transfer plane (direct raw binary):**
+  - existing `VoiceFetchRequest` / `ImageFetchRequest`
+  - existing `VoicePacket` / `ImagePacket`
+
+Swarm mode does not broadcast media payloads. It fans out raw control requests
+to reachable peers, collects raw availability responses, and then fetches media
+from the best responder.
+
+## 2. Problem It Solves
+
+Without swarm mode, media fetch is limited to the original sender's direct raw
+path. If that sender goes offline, moves, or stops responding, a receiver can
+be left with a partial session even when other peers already hold useful
+fragments.
+
+Swarm mode lets the receiver discover alternate peers and fetch the missing
+subset directly from them.
+
+## 3. Control Messages
+
+### 3.1 Media Swarm Request (binary)
+
+```text
+[magic=0x6d][kind=0x01][mediaType:1B][sessionId:4B][requesterKey6:6B][missingCount:1B][missingIndices...]
+```
+
+Fields:
+
+- `mediaType` — `voice` or `image`
+- `sessionId` — 8 hex chars
+- `requesterKey6` — 12 hex chars identifying the requesting device
+- `missingCount` — `0` means the requester needs all fragments
+- `missingIndices` — exact missing fragment indices when `missingCount > 0`
+
+Example:
+
+```text
+6d 01 02 de ad be ef aa bb cc dd ee ff 03 00 02 09
+```
+
+### 3.2 Media Swarm Availability (binary)
+
+```text
+[magic=0x6d][kind=0x02][mediaType:1B][sessionId:4B][requesterKey6:6B][responderKey6:6B][availableCount:1B][availableIndices...]
+```
+
+Fields:
+
+- `mediaType` — `voice` or `image`
+- `sessionId` — 8 hex chars
+- `requesterKey6` — copied from the swarm request
+- `responderKey6` — 12 hex chars identifying the responding peer
+- `availableCount` — `0` means the responder can satisfy the full request
+- `availableIndices` — exact fragment indices held when `availableCount > 0`
+
+Example:
+
+```text
+6d 02 02 de ad be ef aa bb cc dd ee ff 11 22 33 44 55 66 02 02 09
+```
+
+## 4. Requester Behavior
+
+When a voice or image session is incomplete:
+
+1. Prefer the original sender if its direct raw route is healthy.
+2. If the original sender path is unavailable or not responding, send a raw
+   swarm request to reachable peers with the exact missing fragment indices.
+3. Wait up to **10 seconds** for raw availability responses.
+4. Rank responders by overlap with the current missing set.
+5. Skip the original sender when choosing alternate peers.
+6. Send a direct binary fetch request to the best responder for only the
+   missing subset that responder advertised.
+
+Actual media transfer uses the same `cmdSendRawData` / `pushRawData` path as the
+swarm control messages.
+
+## 5. Responder Behavior
+
+A peer that receives a swarm request:
+
+- checks whether it has fragments for the requested media session
+- replies only if it has at least one requested fragment
+- advertises only fragments it actually holds
+- may reply from:
+  - its outgoing cache, or
+  - a partially/fully received incoming session
+
+This enables torrent-like relay behavior without requiring the peer to be the
+original sender.
+
+## 6. Visibility and Routing
+
+- Swarm control payloads are carried by `cmdSendRawData` and received through
+  `pushRawData`.
+- They are intercepted by the app and **must not be surfaced in chat**.
+- Discovery is a direct raw fan-out to reachable peers, not a public-channel
+  broadcast.
+- Media packets themselves remain direct-route raw packets.
+
+## 7. Constraints
+
+- No firmware changes are required.
+- Swarm mode only helps if at least one peer has already received some useful
+  fragments.
+- Peers can only relay fragments they actually have.
+- Alternate peers still need a valid direct raw route back to the requester.
+- Swarm mode improves recovery from sender-path failure, but it does not change
+  the underlying raw-packet size, airtime, or hop constraints.
