+GitHub Actions runs `xcodebuild clean build analyze` on every push and pull request to `main`. A separate [reproducibility verification workflow](.github/workflows/reproducible-build-check.yml) builds the project twice, normalizes both outputs, and compares them to catch non-determinism regressions.
+
+### Reproducible Builds
+
+Birch supports **functionally equivalent** reproducible builds. Given the same source code and Xcode version, two independent builds will produce the same compiled logic after normalization. Certain metadata bytes (Mach-O UUIDs, timestamps, build-machine identifiers) are expected to differ and are zeroed by the normalization step.
+
+**What IS reproducible** (after normalization): all code-bearing sections, resources, and application logic.
+
+**What is NOT reproducible**: code signing timestamps, Mach-O LC_UUID values, Xcode build-machine metadata, App Store .ipa files (Apple re-signs and applies FairPlay DRM).
+
+#### Prerequisites
+
+- Exact Xcode version matching `.xcode-version` (currently 26.4)
+- macOS with the matching SDK
+
+#### Producing a verifiable build
+
+```bash
+./scripts/build-release.sh
+```
+
+This creates an unsigned archive at `/tmp/birch-build/birch.xcarchive`.
+
+#### Verifying two builds
+
+```bash
+# Normalize both builds
+./scripts/normalize-app.sh /path/to/build1.app
+./scripts/normalize-app.sh /path/to/build2.app
+
+# Compare
+./scripts/compare-builds.sh /path/to/build1.app /path/to/build2.app
+```
+
+The comparison exits 0 if the builds are functionally equivalent, 1 if code differences are found.
+
+## Generating Screenshots
+
+Birch uses [`fastlane snapshot`](https://docs.fastlane.tools/actions/snapshot/) to generate marketing and App Store screenshots. A single UI test walks the app from Welcome through the main tabs, capturing every major screen on each configured device in both dark and light mode.
+
+### One-time setup
+
+1. Install [Bundler](https://bundler.io/) if you don't already have it:
+   ```bash
+   gem install bundler
+   ```
+2. Install fastlane via the project `Gemfile`:
+   ```bash
+   bundle install
+   ```
+3. Install [ImageMagick](https://imagemagick.org/) — used to composite iPhone 13 mini screenshots onto their bezel (frameit's bundled 13 mini frame has a pixel-misalignment bug that leaves a visible gap, so we bypass frameit for that device):
+   ```bash
+   brew install imagemagick
+   ```
+4. Patch the installed fastlane gem with iPhone 16/17 device support (from
+   [fastlane PR #29921](https://github.com/fastlane/fastlane/pull/29921)):
+   ```bash
+   bundle exec ruby scripts/patch-frameit.rb
+   ```
+   This is idempotent — safe to re-run. If you upgrade fastlane, the script
+   aborts with a clear error so you can review the patch for the new version.
+
+   On a fresh machine, also download the device frame PNGs before running
+   the patch (they live at `~/.fastlane/frameit/latest/` and are not in the repo):
+   ```bash
+   bundle exec fastlane frameit download_frames
+   ```
+
+5. Make sure the required simulators are downloaded. The screenshot lane targets:
+   - **iPhone 17 Pro Max** (6.9")
+   - **iPhone 17 Pro** (6.3")
+   - **iPhone 11 Pro Max** (6.5")
+   - **iPhone 13 mini** (5.4")
+
+   You can trigger a download by booting them once in Xcode (**Window → Devices and Simulators → Simulators → +**) or via the command line:
+   ```bash
+   xcrun simctl list devices | grep -E "iPhone 17 Pro Max|iPhone 17 Pro|iPhone 11 Pro Max|iPhone 13 mini"
+   ```
+
+### Running
+
+From the repo root:
+
+```bash
+bundle exec fastlane screenshots
+```
+
+This runs the `screenshots` lane defined in [`fastlane/Fastfile`](fastlane/Fastfile), which:
+
+1. Captures all 23 stops in **dark mode** first (the product's default aesthetic)
+2. Captures the same stops in **light mode**
+3. Moves iPhone 13 mini bare captures aside (frameit's bundled 13 mini frame has a pixel-misalignment bug)
+4. Runs `frameit` to composite device bezels onto iPhone 17 Pro Max, iPhone 17 Pro, and iPhone 11 Pro Max screenshots
+5. Moves every `*_framed.png` into a sibling `framed/` subfolder
+6. Composites iPhone 13 mini captures onto the bezel directly with ImageMagick (upscaling to 1086×2353 so the screenshot fully covers the frame's screen hole) and writes the result into the same `framed/` directory
+
+Output lands in:
+
+```
+fastlane/screenshots/
+├── dark/
+│   ├── en-US/
+│   │   ├── iPhone 17 Pro Max-01-Welcome.png

+    └── ...
+```
+
+### How it works
+
+- [`birchUITests/ScreenshotTests.swift`](birchUITests/ScreenshotTests.swift) is a dedicated XCUITest that walks the app. It reuses the existing `-UITesting` launch argument (defined in `birch/birchApp.swift`), which wipes `UserDefaults`/keychain and uses an in-memory SwiftData store so every run starts from a deterministic Welcome screen.
+- The test imports a real testnet4 1-of-2 `wsh(sortedmulti(...))` descriptor with live history, waits for Electrum sync, then visits each screen.
+- Dark/light mode is driven by the simulator's OS appearance (`xcrun simctl ui ... appearance`). The app's `RootView` follows the OS when the theme is set to `.system`, which it is by default after the `-UITesting` wipe, so no app-side toggle is required.
+- The device matrix, scheme, status bar override, and other `snapshot` options live in [`fastlane/Snapfile`](fastlane/Snapfile). Device destinations (simulator OS version), the frameit pass, and the custom 13 mini ImageMagick composite all live in [`fastlane/Fastfile`](fastlane/Fastfile).
+
+### Customizing
+
+- **Add/remove devices:** edit both the `devices([...])` array in `fastlane/Snapfile` and the `DEVICES` hash in `fastlane/Fastfile`.
+- **Change which screens are captured:** edit `testScreenshotTour` in `birchUITests/ScreenshotTests.swift` and add or remove `snapshot("NN-Name")` calls.
+- **Skip framing:** remove the `frameit(...)` lines and the ImageMagick composite block (steps 4–7) from `fastlane/Fastfile` if you only need the bare PNGs.
+
+> **Known workaround** (contained in `fastlane/Fastfile`): `frameit` gem 2.232.2's bundled iPhone 13 Mini frame PNG has a ~3-pixel placement-offset bug that leaves a visible edge gap, so 13 mini is composited directly with ImageMagick instead. iPhone 16/17 device support is patched in via `scripts/patch-frameit.rb` (see setup step 4 above).
