+            3. If you used `*-ios-runner-app.zip`, create a signed `.ipa` from `Runner.app` during signing.
+            4. Install the signed `.ipa` on your iPhone using Apple Configurator 2 or Xcode (Devices and Simulators).

+
+MeshCore SAR helps teams coordinate in low-connectivity or no-connectivity environments with messaging, voice, images, maps, and live location context in one app.
+It uses the MeshCore protocol over LoRa for long-range, infrastructure-free communication.
+`iOS TestFlight:` https://testflight.apple.com/join/tngpPF12
+
+## Highlights
+
+- Rapid mesh chat for both 1:1 and group coordination
+- On-demand voice (Codec2) and image (AVIF) transfer tuned for low-bandwidth links
+- Offline-first mapping with tactical overlays and SAR incident markers
+- Live team location, movement trails, and shareable tactical drawings
+
+## Demo Video

+
+## Feature Overview
+
+| Area | What you get |
+|---|---|
+| Messaging | Direct and group chat over mesh, with contact/room awareness from live telemetry |
+| Voice | Push-to-talk voice clips (Codec2), fetched on demand when play is pressed, auto-play on completion |
+| Images | Camera/gallery image sending (AVIF), auto-compression, tap-to-load receiving, full-screen viewer |
+| Maps | Street/topo/satellite/terrain layers, offline tile downloads, optional MBTiles import |
+| SAR Operations | Team markers with freshness indicators, SAR markers for incidents and staging points |
+| Tracking | Continuous GPS updates, personal trails, distance/duration trail stats |
+| Trail Interop | GPX export/import for trail sharing and reuse |
+| Tactical Drawing | Line/rectangle drawing, distance measurement, drawing sharing to channel/room |
+
+## Voice, Image, and Maps
+
+### Voice
+- Built for short, urgent field communication
+- On-demand playback fetch reduces unnecessary mesh traffic
+- Ideal when typing is impractical during active operations
+
+### Images
+- Pre-send optimization for constrained links
+- Tap-to-load receiving keeps channels lightweight
+- Full-screen view supports rapid field verification
+
+### Maps
+- Works in both online and offline workflows
+- SAR context with team markers, incident markers, and orientation tools
+- Combines location, messaging, and tactical layers in one place
+
+## Built For
+
+- Search and Rescue field teams
+- Incident command and coordination roles
+- Operators working in weak/no cellular coverage
+
+## Connecting Your Radio (BLE)
+
+The app pairs with your MeshCore radio over Bluetooth Low Energy.
+
+### Windows
+
+On Windows 11 (tested on 25H2), pair the radio through the system Bluetooth menu **before** connecting in the app:
+
+1. Open **Settings → Bluetooth & devices → Add device → Bluetooth**.
+2. Select your MeshCore radio and complete pairing, entering the **PIN** when prompted.
+3. Launch MeshCore SAR and connect — the radio now appears as a paired device.
+
+If the radio does not show up or fails to connect in-app, remove it from the Windows Bluetooth menu and repeat the pairing step.
+
+### iOS / Android
+
+Connect directly from within the app — no separate system pairing step is required.
+
+## Permissions (App Use)
+
+- Bluetooth: mesh device communication
+- Location: team tracking and map position updates
+- Microphone: voice clip recording
+- Camera / Photos: image messaging

+# 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
+
+- Never reuse or lower an Android `versionCode`.
+- If a Play release is bad, halt rollout in Play Console and ship a new higher-version fix.
+- Keep GitHub direct APK and Play AAB artifacts separate; do not upload APKs to Play.

+# Image Mode Technical Design
+
+## 1. Overview
+
+Image mode mirrors the voice on-demand architecture exactly, including
+swarm-assisted recovery for stalled partial transfers:
+
+- **Control plane (text messages):**
+  - `IE4:` image envelope announces image availability in chat.
+- **Control plane (raw binary request):**
+  - Binary image fetch request (same raw route as image fragments).
+- **Data plane (raw binary packets):**
+  - `ImagePacket` binary payload streamed via `cmdSendRawData` / `pushRawData`.
+
+Images are never broadcast in full to channels.  Chat carries only metadata;
+pixels are fetched on demand when the user taps the image bubble.
+
+Shared swarm fallback is documented in
+[Swarm Mode Technical Design](./swarm-mode-technical.md).
+
+## 2. Key Modules
+
+- `lib/utils/image_message_parser.dart`
+  - `ImagePacket` (binary fragment format)
+  - `ImageEnvelope` (`IE4`)
+  - `ImageFetchRequest` (binary)
+  - `fragmentImage()` — split compressed bytes into packets
+  - `reassembleImage()` — join received fragments into bytes
+- `lib/screens/messages_tab.dart`
+  - Pick image from gallery or camera, compress with user settings, cache, send envelope
+- `lib/providers/image_provider.dart`
+  - Reassembly sessions, outgoing cache, deferred serving
+  - Outgoing sessions also registered as complete incoming sessions for immediate local display
+  - Received partial sessions can be re-served during swarm recovery
+- `lib/providers/app_provider.dart`
+  - Incoming routing for `IE4`, binary image fetch requests, binary `0x49` packets, and raw swarm control payloads
+- `lib/widgets/messages/image_message_bubble.dart`
+  - Square cover thumbnail (up to 256 px); tap-to-load for received images;
+    progress ring during fetch; full-screen `InteractiveViewer` on tap
+- `lib/services/image_codec_service.dart`
+  - `ImageCodecService.compress()` — aspect-ratio-preserving resize + optional
+    grayscale + AVIF encode via `flutter_avif`
+- `lib/services/image_preferences.dart`
+  - `ImagePreferences` — persists max size, compression level, grayscale toggle
+
+## 3. Wire Formats
+
+### 3.1 Image Envelope (`IE4`)
+
+Prefix: `IE4:` + colon-delimited compact payload (base36 numeric fields)
+
+Fields:
+
+| Field        | Type   | Description                                    |
+|--------------|--------|------------------------------------------------|
+| `sid`        | string | base36 token for 32-bit session ID             |
+| `fmt`        | base36 | `ImageFormat.id` (0 = AVIF, 1 = JPEG)         |
+| `total`      | base36 | Fragment count (1..255)                        |
+| `w`          | base36 | Actual image width after compression (pixels)  |
+| `h`          | base36 | Actual image height after compression (pixels) |
+| `bytes`      | base36 | Total compressed size in bytes                 |
+Compact format:
+
+```text
+IE4:{sid}:{fmt}:{total}:{w}:{h}:{bytes}
+```
+
+Example (256×171 landscape image, 14 fragments):
+
+```text
+IE4:a:0:e:74:4r:1mc
+```
+
+Note: `sid` is base36 on wire and expands to 8-hex internally.
+`w` and `h` reflect the actual post-compression dimensions, which preserve
+the source aspect ratio (contain within the configured max size).
+
+### 3.2 Image Fetch Request (`IR4` + binary)
+
+Text format:
+
+```text
+IR4:{sid}:{want}:{requesterKey6}
+```
+
+Binary payload format:
+
+```text
+[magic=0x69][sid:4B][flags:1B][requesterKey6:6B][missingCount:1B][missingIndices...]
+```
+
+| Field            | Value                    |
+|------------------|--------------------------|
+| `flags`          | bit0=1 => request missing indices, else all |
+| `requesterKey6`  | 6-byte requester key prefix |
+### 3.3 Raw Image Packet (data plane)
+
+Binary payload structure:
+
+- Byte 0: magic `0x49` (`'I'`)
+- Bytes 1..4: session ID (4 bytes)
+- Byte 5: fragment index (0-based)
+- Bytes 6..N: image data (max 152 bytes per fragment)
+
+Header is 6 bytes. Image format and total fragment count come from the `IE4` envelope.
+
+## 4. Compression Pipeline
+
+`ImageCodecService.compress(rawBytes, {maxDimension, compression, grayscale})`:
+
+1. **Probe** — decode source image at original resolution to read `srcW × srcH`.
+2. **Contain** — compute `dstW × dstH` that fits within `maxDimension × maxDimension`
+   while preserving aspect ratio.  Images smaller than the cap are not upscaled.
+3. **Decode** — `dart:ui.instantiateImageCodec` with `targetWidth: dstW, targetHeight: dstH`.
+4. **RGBA export** — `image.toByteData(format: rawRgba)`.
+5. **Grayscale** *(optional, default on)* — luminance `0.299R + 0.587G + 0.114B`
+   applied in-place; if disabled, colour pixels are passed through unchanged.
+6. **PNG re-encode** — `ui.ImageDescriptor.raw` → `toByteData(format: png)`.
+   Required because `encodeAvif()` takes an encoded image, not raw RGBA.
+7. **AVIF encode** — `flutter_avif.encodeAvif(pngBytes, maxQuantizer, minQuantizer, speed: 8)`.
+   `compression` (10–90) maps to libavif CQ scale:
+   `maxQ = round(compression/100 × 63)`, `minQ = round(maxQ × 0.65)`.
+8. **Fragment** — `fragmentImage()` at 152 bytes/packet (≤255 packets).
+
+Returns `({Uint8List bytes, int width, int height})` with the actual compressed dimensions.
+
+### User-configurable settings (`ImagePreferences`)
+
+| Setting      | Key                | Default | Range / Options |
+|--------------|--------------------|---------|-----------------|
+| Max size     | `image_max_size`   | 256     | 64 / 128 / 256  |
+| Compression  | `image_quality`    | 90      | 10–90           |
+| Grayscale    | `image_grayscale`  | true    | true / false    |
+
+### Expected sizes (grayscale AVIF, compression 90)
+
+| Max size | Typical size | Fragments |
+|----------|--------------|-----------|
+| 64×64    | 100–400 B    | 1–3       |
+| 128×128  | 300–900 B    | 2–6       |
+| 256×256  | 700–3000 B   | 5–20      |
+
+Non-square images produce fewer fragments than the square equivalent because
+only the shorter axis is padded — no cropping occurs.
+
+## 5. Outgoing Flow (Send)
+
+1. User picks image from gallery or camera (`image_picker`).
+2. `ImagePreferences` is read: max size, compression, grayscale.
+3. `ImageCodecService.compress()` returns `(bytes, width, height)`.
+4. `fragmentImage()` splits bytes into `ImagePacket` list (≤255 fragments).
+5. `ImageProvider.cacheOutgoingSession()` stores fragments in both the outgoing
+   cache (for serving to peers) and the incoming session map (so the local bubble
+   renders the image immediately without a fetch round-trip).
+6. `ImageEnvelope` built with actual `width`/`height` from step 3.
+7. Envelope sent via normal message path:
+   - Channel: `sendChannelMessage`
+   - Direct: `sendTextMessage`
+8. Local placeholder message added (`IE4:` text, `deliveryStatus.sending`).
+
+## 6. Incoming Flow (Receive)
+
+### 6.1 `IE4` envelope received
+
+`AppProvider` calls `imageProvider.registerEnvelope()` and adds the message to
+chat.  The bubble shows a grey square placeholder with a download icon.
+
+### 6.2 Binary image fetch request received
+
+`AppProvider` treats it as control-plane only (not added to chat):
+
+- Resolves requester contact.
+- Calls `imageProvider.serveSessionTo()` which streams all cached fragments.
+
+### 6.3 Swarm control messages received
+
+`AppProvider` also handles shared raw swarm discovery payloads:
+
+- binary swarm requests advertise which image fragments are still missing
+- binary swarm availability responses advertise which fragments another peer can relay
+- swarm payloads arrive via `pushRawData` and are intercepted instead of being added to chat
+
+Shared discovery and responder semantics are documented in
+[Swarm Mode Technical Design](./swarm-mode-technical.md).
+
+### 6.4 Raw packet received (`pushRawData`, magic `0x49`)
+
+`AppProvider.onRawDataReceived` parses `ImagePacket` binary and calls
+`imageProvider.addFragment()`.  When the session becomes complete, the bubble
+automatically rebuilds with the full image.
+
+## 7. Outgoing Cache Details
+
+`ImageProvider` outgoing cache:
+
+- key: `sessionId`
+- value: encoded fragment list + cached envelope + timestamp
+- TTL: 15 minutes
+- eviction: lazy on access
+
+When `cacheOutgoingSession()` is called it also writes all fragments into
+`_sessions[sessionId]`, so the sender sees the image immediately in the bubble
+(no tap-to-load required for own messages).
+
+If a peer later receives only part of an image session, those received fragments
+can also be served onward to another requester during swarm recovery.
+
+## 8. Display
+
+`ImageMessageBubble` (max width 256 px):
+
+- **Complete session**: `AspectRatio(1.0)` → `AvifImage.memory(fit: cover)`
+  square thumbnail; tap → full-screen `InteractiveViewer` with fade transition.
+- **Incomplete/missing**: grey square placeholder with download icon;
+  tap → sends binary fetch request, with raw swarm fallback if the original
+  sender path stalls.
+- **Loading**: circular progress indicator showing `received/total` count.
+- **Error**: broken-image icon.
+
+Status line below thumbnail:
+
+- Sender: `🖼️ {w}×{h} AVIF · {n} seg`
+- Receiver (complete): `🖼️ {w}×{h} AVIF`
+- Receiver (pending): `🖼️ Tap to load · {w}×{h}`
+- Loading: `📥 Loading… {received}/{total}`
+
+## 9. Transmit Time Estimate (UI)
+
+Image bubbles and Message Technical Details show an **estimated transmit time** (`~... tx`).
+
+The estimate is airtime-based (LoRa packet model), not just compressed image size:
+
+- Source inputs:
+  - `total` fragments and `bytes` from `IE4` envelope
+  - all numeric envelope values are decoded from base36
+  - `pathLen` from message metadata
+  - current radio params from `deviceInfo`: `radioBw`, `radioSf`, `radioCr`
+- Per-fragment payload model:
+  - `meshHeader(2)` + `pathLen` + `imageHeader(6)` + `fragmentBytes`
+- LoRa airtime:
+  - standard symbol-time formula (preamble + payload symbols)
+- Mesh pacing/hops:
+  - multiplied by `(1 + airtimeBudgetFactor)` where default factor is `1.0`
+  - multiplied by hop count `(pathLen + 1)`
+- Total estimate:
+  - sum over all fragments
+
+BW handling:
+
+- If `radioBw` is index `0..9`, app maps it to Hz (`7.8k` .. `500k`)
+- If `radioBw > 1000`, it is treated as Hz directly
+
+Fallback defaults are used when radio params are unavailable: `SF10`, `BW250kHz`, `CR5`.
+
+## 10. Persistence
+
+`ImageProvider` stores sessions in `SharedPreferences` under key
+`stored_image_sessions_v1`:
+
+- Incoming: fragment list serialized as base64 binary packets.
+- Outgoing: fragment list + envelope text + `cachedAt` timestamp.
+- Expired outgoing sessions (> 15 min) are not restored on startup.
+
+## 11. Operational Constraints
+
+- No firmware changes required (reuses `cmdSendRawData` / `pushRawData`).
+- On-demand fetch prefers the original sender, but a partial image can also be
+  completed from alternate peers that already hold matching fragments.
+- Raw return path requires a valid direct route to requester.
+- Available on iOS and Android (`image_picker` + `flutter_avif`).
+- Swarm discovery uses the same `cmdSendRawData` / `pushRawData` path as image
+  fetch and fragment delivery.
+
+### 11.1 Raw Binary Routing Semantics
+
+- Image fragment payloads use companion command `CMD_SEND_RAW_DATA` (`25` / `0x19`).
+- Companion push back to the app is `PUSH_CODE_RAW_DATA` (`0x84`).
+- Over-the-air packet type for this flow is `PAYLOAD_TYPE_RAW_CUSTOM` (`0x0F`).
+- This flow is direct-route only, not flood/broadcast:
+  - it is sent to one destination path;
+  - only nodes on that path relay it;
+  - it is **not** received by everyone in the mesh.
+

+# 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.
+

+# Voice Mode Technical Design
+
+## 1. Overview
+
+Voice mode uses a **two-plane architecture** with optional swarm-assisted
+recovery:
+
+- **Control plane (text messages):**
+  - `VE3:` voice envelope announces voice availability in chat.
+- **Control plane (raw binary request):**
+  - Binary voice fetch request (same raw route as voice packets).
+- **Data plane (raw binary packets):**
+  - `VoicePacket` payload streamed via `cmdSendRawData` and received through `pushRawData`.
+
+This design avoids broadcasting full voice payloads to channels/rooms. Chat carries only metadata; audio is fetched on demand when user presses play.
+
+Swarm fallback is documented in [Swarm Mode Technical Design](./swarm-mode-technical.md).
+
+## 2. Key Modules
+
+- `lib/utils/voice_message_parser.dart`
+  - `VoicePacket` (binary direct-packet format)
+  - `VoiceEnvelope` (`VE3`)
+  - `VoiceFetchRequest` (binary)
+- `lib/screens/messages_tab.dart`
+  - Capture/encode voice, cache encoded packets, send envelope only
+- `lib/providers/voice_provider.dart`
+  - Reassembly/playback sessions
+  - Outgoing session cache + deferred serving
+- `lib/providers/app_provider.dart`
+  - Incoming routing for `VE3`, binary voice fetch requests, and raw swarm control payloads
+  - Handles raw packet ingestion
+- `lib/widgets/messages/voice_message_bubble.dart`
+  - Play behavior (immediate play if complete, otherwise fetch + auto-play)
+- `lib/providers/messages_provider.dart`
+  - Message-level voice detection (`VE3`)
+- `lib/services/message_storage_service.dart`
+  - Persists `isVoice` and `voiceId`
+
+## 3. Wire Formats
+
+### 3.1 Voice Envelope (`VE3`)
+
+Prefix: `VE3:` + colon-delimited compact payload (base36 numeric fields)
+
+Fields:
+
+- `sid` (string): base36 token for 32-bit session ID
+- `mode` (base36): codec mode ID (`VoicePacketMode.id`)
+- `total` (base36): packet count (1..255)
+- `durS` (base36): estimated duration in seconds
+
+`sid` is base36 on wire and expands to 8-hex internally.
+
+Compact format:
+
+```text
+VE3:{sid}:{mode}:{total}:{durS}
+```
+
+Example:
+
+```text
+VE3:a:1:4:4
+```
+
+### 3.2 Voice Fetch Request (binary)
+
+Binary payload format:
+
+```text
+[magic=0x72][sid:4B][flags:1B][requesterKey6:6B][missingCount:1B][missingIndices...]
+```
+
+### 3.3 Raw Voice Packet (data plane)
+
+Binary payload structure:
+
+- Byte 0: magic `0x56` (`'V'`)
+- Bytes 1..4: session ID (4 bytes)
+- Byte 5: packet index
+- Bytes 6..N: codec2 data
+
+Header is 6 bytes. Mode and total packet count come from the `VE3` envelope.
+
+## 4. Outgoing Flow (Send)
+
+1. Recorder captures PCM chunks.
+2. Each chunk is codec2-encoded into `VoicePacket` objects.
+3. Packets are cached in `VoiceProvider` outgoing cache (TTL 15 min).
+4. Sender inserts local voice placeholder message (`isVoice=true`, `voiceId=sessionId`).
+5. Sender sends one envelope (`VE3`) through normal message path:
+   - channel/room: `sendChannelMessage`
+   - direct: `sendTextMessage`
+6. **No raw audio packets are sent during initial send.**
+
+## 5. Incoming Routing
+
+### 5.1 `VE3` envelope received
+
+`AppProvider` records sender identity from message metadata, registers the voice
+session envelope, marks the message as voice (`isVoice`, `voiceId`), and adds it to chat.
+
+### 5.2 Binary voice fetch request received
+
+`AppProvider` treats it as control-plane only:
+
+- request is not added to chat
+- resolves requester contact via key prefix
+- calls `voiceProvider.serveSessionTo(...)`
+
+### 5.3 Swarm control messages received
+
+`AppProvider` also handles raw swarm control payloads:
+
+- binary swarm requests advertise which voice fragments are still missing
+- binary swarm availability responses advertise which fragments a peer can relay
+- swarm control payloads arrive via `pushRawData` and are not added to chat history
+
+Swarm semantics are shared with image mode and documented in
+[Swarm Mode Technical Design](./swarm-mode-technical.md).
+
+### 5.4 Raw packet received (`pushRawData`)
+
+`AppProvider.onRawDataReceived` parses `VoicePacket` binary and appends to session in `VoiceProvider`.
+
+## 6. Play / Fetch Behavior
+
+In `VoiceMessageBubble`:
+
+- If session already complete: play immediately.
+- If incomplete/missing:
+  1. Resolve sender contact from message sender metadata
+  2. Prefer a direct fetch from the original sender if its raw route is healthy
+  3. If the sender path does not respond, fan out a raw swarm request with the
+     exact missing packet indices to reachable peers
+  4. Wait up to 10 seconds for raw peer availability responses
+  5. Send a direct binary fetch request to the best alternate peer for the
+     missing subset it advertised
+  6. Show requesting state in UI
+  7. Auto-play when session becomes complete
+
+If sender cannot be resolved or request cannot be sent, bubble remains and shows: **"Voice unavailable right now"**.
+
+## 7. Outgoing Cache Details
+
+`VoiceProvider` outgoing cache:
+
+- key: `sessionId`
+- value: encoded packet list + cached timestamp
+- TTL: 15 minutes (`_outgoingSessionTtl`)
+- eviction: lazy (on cache access/add/serve)
+
+Serving prerequisites:
+
+- session exists in outgoing cache or already-received session state
+- `sendRawPacketCallback` configured
+- requester has direct path (`outPathLen >= 0`)
+
+Received partial sessions can therefore act as relay sources during swarm
+recovery.
+
+## 8. Persistence
+
+`MessageStorageService` now stores and restores:
+
+- `isVoice`
+- `voiceId`
+
+This ensures envelope messages remain voice bubbles across app restart.
+
+## 9. Validation and Safety
+
+Parser validation enforces:
+
+- strict hex lengths for IDs and key prefixes
+- valid mode range
+- valid packet counts and duration bounds
+- compact base36 numeric fields in envelope/request
+- Binary request flags specify `all` or `missing` indices.
+- Request payload includes `requesterKey6` to resolve return route.
+
+## 10. Transmit Time Estimate (UI)
+
+Voice bubbles and Message Technical Details show an **estimated transmit time** (`~... tx`).
+
+The estimate is airtime-based (LoRa packet model), not file-duration-only:
+
+- Source inputs:
+  - `packetCount` and `durationMs` from `VE3` envelope, or
+  - numeric envelope values decoded from base36
+  - actual received `VoicePacket.codec2Data.length` bytes when local session packets exist
+  - `pathLen` from message metadata
+  - current radio params from `deviceInfo`: `radioBw`, `radioSf`, `radioCr`
+- Per-packet payload model:
+  - `meshHeader(2)` + `pathLen` + `voiceHeader(6)` + `codec2Bytes`
+- LoRa airtime:
+  - standard symbol-time formula (preamble + payload symbols)
+- Mesh pacing/hops:
+  - multiplied by `(1 + airtimeBudgetFactor)` where default factor is `1.0`
+  - multiplied by hop count `(pathLen + 1)`
+- Total estimate:
+  - sum over all packets
+
+BW handling:
+
+- If `radioBw` is index `0..9`, app maps it to Hz (`7.8k` .. `500k`)
+- If `radioBw > 1000`, it is treated as Hz directly
+
+Fallback defaults are used when radio params are unavailable: `SF10`, `BW250kHz`, `CR5`.
+
+## 11. Operational Constraints
+
+- No firmware changes required.
+- On-demand fetch prefers the original sender, but a partial session can also be
+  completed from alternate peers that already hold packets.
+- Raw return path needs a currently valid direct route to requester.
+- Voice capture is available on iOS and Android (`Platform.isIOS || Platform.isAndroid`).
+- Swarm discovery uses the same `cmdSendRawData` / `pushRawData` path as voice
+  fetch and packet delivery.
+
+### 11.1 Raw Binary Routing Semantics
+
+- Voice payload packets use companion command `CMD_SEND_RAW_DATA` (`25` / `0x19`).
+- Companion push back to the app is `PUSH_CODE_RAW_DATA` (`0x84`).
+- Over-the-air packet type for this flow is `PAYLOAD_TYPE_RAW_CUSTOM` (`0x0F`).
+- This flow is direct-route only, not flood/broadcast:
+  - it is sent to one destination path;
+  - only nodes on that path relay it;
+  - it is **not** received by everyone in the mesh.

+MeshCore SAR gives search and rescue teams a field-ready coordination workspace for low-connectivity operations.
+
+Use mesh chat, live location context, SAR markers, offline-first maps, tactical drawings, voice clips, and compressed image transfer in one app. The app is built around MeshCore and BLE so teams can coordinate over LoRa links when normal infrastructure is weak or unavailable.
+
+Key capabilities:
+- Direct and group mesh messaging
+- Live team contacts with signal, battery, and location context
+- Offline maps with SAR markers and tactical overlays
+- Voice clips optimized for low-bandwidth links
+- Image transfer with compact encoding
+- GPX trail import/export
+- Incident, staging, and discovery workflows for field teams
+
+MeshCore SAR is intended for search and rescue field teams, incident command, and operators who need practical coordination tools outside normal coverage.

+/// Callers can lookup localized strings with an instance of AppLocalizations
+/// returned by `AppLocalizations.of(context)`.
+///
+/// Applications need to include `AppLocalizations.delegate()` in their app's
+/// `localizationDelegates` list, and the locales they support in the app's
+/// `supportedLocales` list. For example:
+///
+/// ```dart
+/// import 'l10n/app_localizations.dart';
+///
+/// return MaterialApp(
+///   localizationsDelegates: AppLocalizations.localizationsDelegates,
+///   supportedLocales: AppLocalizations.supportedLocales,
+///   home: MyApplicationHome(),
+/// );
+/// ```
+///
+/// ## Update pubspec.yaml
+///
+/// Please make sure to update your pubspec.yaml to include the following
+/// packages:
+///
+/// ```yaml
+/// dependencies:
+///   # Internationalization support.
+///   flutter_localizations:
+///     sdk: flutter
+///   intl: any # Use the pinned version from flutter_localizations
+///
+///   # Rest of dependencies
+/// ```
+///
+/// ## iOS Applications
+///
+/// iOS applications define key application metadata, including supported
+/// locales, in an Info.plist file that is built into the application bundle.
+/// To configure the locales supported by your app, you’ll need to edit this
+/// file.
+///
+/// First, open your project’s ios/Runner.xcworkspace Xcode workspace file.
+/// Then, in the Project Navigator, open the Info.plist file under the Runner
+/// project’s Runner folder.
+///
+/// Next, select the Information Property List item, select Add Item from the
+/// Editor menu, then select Localizations from the pop-up menu.
+///
+/// Select and expand the newly-created Localizations item then, for each
+/// locale your application supports, add a new item and select the locale
+/// you wish to add from the pop-up menu in the Value field. This list should
+/// be consistent with the languages listed in the AppLocalizations.supportedLocales
+/// property.

+# MeshCore SAR Stats Worker
+
+This worker follows the same split as `/Users/dz0ny/site-vendorvigilance`:
+
+- Astro builds the dashboard UI into `dist`
+- a small Cloudflare Worker handles `/api/*` before assets are served
+
+## Layout
+
+- `src/pages/index.astro` - dashboard shell
+- `worker/index.ts` - Cloudflare Worker entrypoint
+- `worker/stats.ts` - D1 queries, payload validation, and aggregation helpers
+- `public/.assetsignore` - keeps Astro's private `_worker.js` bundle out of public asset uploads
+- `schema.sql` - D1 schema
+
+## Setup
+
+1. Install dependencies with `bun install`.
+2. Create a D1 database with `bunx wrangler d1 create meshcore_sar_rx_stats`.
+3. Apply the schema with `bunx wrangler d1 execute meshcore_sar_rx_stats --remote --file=./schema.sql`.
+4. Add the real D1 binding id to `wrangler.toml` when deploying.
+5. Build the dashboard with `bun run build`.
+6. Run checks with `bun run check`, `bun run test`, and `bun run typecheck`.
+
+## Routes
+
+- `GET /` - static Astro dashboard
+- `GET /api/dashboard?window=24h|7d|30d` - aggregated dashboard JSON
+- `POST /api/ingest` - anonymous RX stats ingest
