# Why

Add a small Swift helper for recording iOS Simulator screen output from EAS build workers. The helper produces either segmented fMP4 output with manifest metadata for playlist construction or one continuous MP4 when segmentation is disabled.

# How

- Added a `record-sim` Swift package under `@expo/build-tools` resources.
- Added `yarn workspace @expo/build-tools build:record-sim` for local builds into `packages/build-tools/bin/record-sim`.
- Updated iOS worker packaging to build `record-sim` from source and copy only the executable into the worker archive.
- Ignored the generated local `bin/record-sim` binary.

# Test Plan

- `yarn workspace @expo/build-tools build:record-sim`
- `packages/build-tools/bin/record-sim --help`
- `bash -n packages/worker/package.sh`
- `yarn workspace @expo/build-tools typecheck`
- `./node_modules/.bin/oxfmt --check packages/build-tools/.gitignore packages/build-tools/package.json packages/worker/package.sh packages/build-tools/src/index.ts`

+# RecordSim
+
+Small Swift library for non-exclusive iOS Simulator screen recording.
+
+It implements one recording path:
+
+1. Listen to SimRenderServer framebuffer callbacks.
+2. Copy the live `IOSurface` immediately into an owned `CVPixelBuffer`.
+3. Feed one continuous `AVAssetWriter`.
+4. Emit Apple HLS/CMAF-style fragmented MP4 segments.
+
+The output is suitable for uploading while recording. `session.json` contains
+the ordered segment metadata needed to build a playlist later.
+
+## Output
+
+```text
+session/
+  init.mp4
+  session.json
+  segments/
+    segment-000000.m4s
+    segment-000001.m4s
+```
+
+`init.mp4` is the fMP4 initialization segment. Individual `.m4s` files are not
+standalone MP4 files. `session.json` stores the wall-clock timestamp for the
+first video frame plus the metadata needed to build a playlist: HLS version,
+target duration, media sequence, `initSegment`, and the ordered `segments` array
+with file path and duration for each media segment.
+
+## CLI
+
+```bash
+swift run record-sim \
+  --udid <BOOTED_SIMULATOR_UDID> \
+  --output /tmp/sim-recording \
+  --segment-duration 120 \
+  --fps 30 \
+  --bitrate 30000000 \
+  --codec h264
+```
+
+For sparse 2h sessions, `--segment-duration 120` is a reasonable default: about
+60 media objects plus the init segment. The recorder appends a single duplicate
+hold frame near each segment boundary when the simulator is idle, so long idle
+periods still produce uploadable segments without encoding idle frames at 60fps.
+Use `--segment-duration 0` to write one continuous `recording.mp4` instead of
+`init.mp4` plus media segments.
+
+Frame timestamps use monotonic host time, not wall-clock time. The recorder also
+probes the framebuffer seed once per second; if the surface changes without
+callbacks for 5 seconds, it captures that frame and rewires the private callback
+registration.
+
+## Library
+
+```swift
+let recorder = SimulatorRecorder(
+  configuration: SimulatorRecordingConfiguration(
+    deviceUDID: udid,
+    outputDirectory: sessionDirectory,
+    segmentDuration: 120
+  )
+)
+
+recorder.onSegment = { segment in
+  // Enqueue upload of segment.url.
+}
+
+try recorder.start()
+try recorder.waitUntilFirstFrame()
+// ...
+let manifest = try recorder.stop()
+```
+
+`session.json` contains the precise wall-clock time for video PTS zero. In
+segmented mode it also contains the init segment and ordered media segment
+file/duration entries; in single-file mode it points at `recording.mp4`.

-## Project Overview
-
 This is an Expo/React Native mobile application. Prioritize mobile-first patterns, performance, and cross-platform compatibility.
 
-## Documentation Resources
+## Expo has changed — do not trust your training data
 
-When working on this project, **always consult the official Expo documentation** available at:
+Expo ships breaking changes every SDK release. APIs you remember are likely renamed, moved, or removed. Before writing any code that touches an Expo, EAS, or React Native API:
 
-- **https://docs.expo.dev/llms.txt** - Index of all available documentation files
-- **https://docs.expo.dev/llms-full.txt** - Complete Expo documentation including Expo Router, Expo Modules API, development process
-- **https://docs.expo.dev/llms-eas.txt** - Complete EAS (Expo Application Services) documentation
-- **https://docs.expo.dev/llms-sdk.txt** - Complete Expo SDK documentation
-- **https://reactnative.dev/docs/getting-started** - Complete React Native documentation
+1. Read the major version of the `expo` package in `package.json`.
+2. Fetch the matching versioned docs: `https://docs.expo.dev/versions/v<major>.0.0/`
+3. For anything else, fetch https://docs.expo.dev/llms.txt — an index of all Expo docs with corrections to common LLM misconceptions. Follow its links to the specific page you need; never answer from memory.
 
-These documentation files are specifically formatted for AI agents and should be your **primary reference** for:
+## Commands
 
-- Expo APIs and best practices
-- Expo Router navigation patterns
-- EAS Build, Submit, and Update workflows
-- Expo SDK modules and their usage
-- Development and deployment processes

-## Essential Commands
-
-### Development
+Use `bunx` instead of `npx` if the project uses bun (`bun.lock` present).
 
 ```bash
-npx expo start                  # Start dev server
-npx expo start --clear          # Clear cache and start dev server
-npx expo install <package>      # Install packages with compatible versions
-npx expo install --check        # Check which installed packages need to be updated
-npx expo install --fix          # Automatically update any invalid package versions
-npm run development-builds      # Create development builds (workflow)
-npm run reset-project           # Reset to blank template
+npx expo install <package>  # ALWAYS use instead of npm/yarn/pnpm/bun add — resolves SDK-compatible versions
+npx expo start              # start the dev server
+npx expo lint               # lint
+npx tsc --noEmit            # typecheck
+npx expo-doctor             # diagnose dependency and config issues
+npx expo install --fix      # fix incompatible package versions
 ```
 
-### Building & Testing
+Run lint and typecheck before declaring any task done.
 
-```bash
-npx expo doctor      # Check project health and dependencies
-npx expo lint        # Run ESLint
-npm run draft        # Publish preview update and website (workflow)
-```
+## Navigation & Routing
 
-### Production
+- Use **Expo Router** for all navigation. Routes live in `src/app/` — every file there is a screen, `_layout.tsx` files define navigators. Keep non-route code (components, hooks, utils) outside `src/app/`.
+- Import `Link`, `router`, and `useLocalSearchParams` from `expo-router`.
+- Docs: https://docs.expo.dev/router/introduction.md
 
-```bash
-npx eas-cli@latest build --platform ios -s          # Use EAS to build for iOS platform and submit to App Store
-npx eas-cli@latest build --platform android -s      # Use EAS to build for Android platform and submit to Google Play Store
-npm run deploy                                      # Deploy to production (workflow)
-```
+## Building with EAS
 
-## Development Guidelines
+Use EAS to build, sign, and submit the app in the cloud (`eas build`, `eas submit`) and to ship over-the-air updates (`eas update`) — no local Xcode or Android Studio required. Run EAS CLI as `bunx eas-cli <command>` in Bun projects, or `npx eas-cli@latest <command>` otherwise; substitute that for bare `eas` in docs examples.
+Docs: https://docs.expo.dev/eas/index.md
 
-### Code Style & Standards
+## Rules
 
-- **TypeScript First**: Use TypeScript for all new code with strict type checking
-- **Naming Conventions**: Use meaningful, descriptive names for variables, functions, and components
-- **Self-Documenting Code**: Write clear, readable code that explains itself; only add comments for complex business logic or design decisions
-- **React 19 Patterns**: Follow modern React patterns including:
-  - Function components with hooks
-  - Enable React Compiler
-  - Proper dependency arrays in useEffect
-  - Memoization when appropriate (useMemo, useCallback)
-  - Error boundaries for better error handling
-
-### Navigation & Routing
-
-- Use **Expo Router** for all navigation
-- Import `Link`, `router`, and `useLocalSearchParams` from `expo-router`
-- Docs: https://docs.expo.dev/router/introduction/
-
-### Recommended Libraries
-
-- **Navigation**: `expo-router` for navigation
-- **Images**: `expo-image` for optimized image handling and caching
-- **Animations**: `react-native-reanimated` for performant animations on native thread
-- **Gestures**: `react-native-gesture-handler` for native gesture recognition
-- **Storage**: Use `expo-sqlite` for persistent storage, `expo-sqlite/kv-store` for simple key-value storage
-
-## Debugging & Development Tools
-
-### DevTools Integration
-
-- **React Native DevTools**: Use MCP `open_devtools` command to launch debugging tools
-- **Network Inspection**: Monitor API calls and network requests in DevTools
-- **Element Inspector**: Debug component hierarchy and styles
-- **Performance Profiler**: Identify performance bottlenecks
-- **Logging**: Use `console.log` for debugging (remove before production), `console.warn` for deprecation notices, `console.error` for actual errors, and implement error boundaries for production error handling
-
-### Testing & Quality Assurance
-
-#### Automated Testing with MCP Tools
-
-Developers can configure the Expo MCP server with the following doc: https://docs.expo.dev/eas/ai/mcp/
-
-- **Component Testing**: Add `testID` props to components for automation
-- **Visual Testing**: Use MCP `automation_take_screenshot` to verify UI appearance
-- **Interaction Testing**: Use MCP `automation_tap_by_testid` to simulate user interactions
-- **View Verification**: Use MCP `automation_find_view_by_testid` to validate component rendering
-
-## EAS Workflows CI/CD
-
-This project is pre-configured with **EAS Workflows** for automating development and release processes. Workflows are defined in `.eas/workflows/` directory.
-
-When working with EAS Workflows, **always refer to**:
-
-- https://docs.expo.dev/eas/workflows/ for workflow examples
-- The `.eas/workflows/` directory for existing workflow configurations
-- You can check that a workflow YAML is valid using the workflows schema: https://exp.host/--/api/v2/workflows/schema
-
-### Build Profiles (eas.json)
-
-- **development**: Development builds with dev client
-- **development-simulator**: Development builds for iOS simulator
-- **preview**: Internal distribution preview builds
-- **production**: Production builds with auto-increment
-
-## Troubleshooting
-
-### Expo Go Errors & Development Builds
-
-If there are errors in **Expo Go** or the project is not running, create a **development build**. **Expo Go** is a sandbox environment with a limited set of native modules. To create development builds, run `eas build:dev`. Additionally, after installing new packages or adding config plugins, new development builds are often required.

-   - For general Expo questions: https://docs.expo.dev/llms-full.txt
-   - For EAS/deployment questions: https://docs.expo.dev/llms-eas.txt
-   - For SDK/API questions: https://docs.expo.dev/llms-sdk.txt
-
-2. **Understand before implementing**: Read the relevant docs section before writing code
-
-3. **Follow existing patterns**: Look at existing components and screens for patterns to follow
+- If `ios/` and `android/` directories do not exist, they are generated (Continuous Native Generation). Never create or edit them by hand — configure native behavior in `app.json` and config plugins.
+- Expo Go only includes its bundled native modules. After adding a library with native code, the app needs a development build: `npx expo run:ios|android` locally, or `eas build --profile development`.
+- Prefer recommended Expo modules over third-party libraries, and check your available skills before adding dependencies. Docs: https://docs.expo.dev/versions/latest/index.md
