Note

Set up EAS CI preview builds for the mobile app

• Adds a pull request workflow that deploys an Expo EAS preview using the new preview:dev profile when EXPO_TOKEN is present; falls back to eas update --no-bytecode if fingerprint deployment fails.
• Adds the preview:dev EAS profile in eas.json with developmentClient=true, internal distribution, APK build type, and MOBILE_VERSION_POLICY=fingerprint.
• Makes the runtimeVersion.policy in app.config.ts configurable via MOBILE_VERSION_POLICY (defaults to appVersion).
• Adds a patch to @expo/metro-config@56.0.13 that strips invalid source map segments before composing maps.
• Adds a .fingerprintignore to exclude build artifacts, tests, and local env files from Expo fingerprinting.

Changes since #2911 opened

• Removed error handling and fallback deployment logic from mobile preview workflow [d7a2294]
• Removed @expo/cli dependency from mobile app package [d7a2294]
• Changed package manager configuration in mobile-eas-preview.yml workflow [d876387]
• Configured the mobile EAS preview workflow to use pnpm instead of vp as the package manager [f313c1f]

Note

Medium Risk
Touches CI secrets and automated Expo deploys plus a patched Metro bundler dependency; no app auth or data-layer changes, but failed or misconfigured previews could affect reviewer access to PR builds.

Overview
Adds automated mobile PR previews via a new workflow (.github/workflows/mobile-eas-preview.yml) that runs only when EXPO_TOKEN is set: checks out the repo, sets up Vite+/pnpm/EAS, pulls preview env vars, and deploys with expo/expo-github-action/continuous-deploy-fingerprint using profile preview:dev, branch pr-<number>, and MOBILE_VERSION_POLICY=fingerprint.

Introduces the preview:dev EAS profile (preview variant + dev client, internal APK on Android, fingerprint runtime policy) and wires runtimeVersion.policy in app.config.ts to MOBILE_VERSION_POLICY (still defaults to appVersion locally/production). Adds eas:ios/android:preview:dev scripts and documents the CI fingerprint flow in the mobile README.

Adds .fingerprintignore so fingerprints ignore build dirs, tests, docs, and local env files. Patches @expo/metro-config@56.0.13 to sanitize invalid Hermes/Metro source-map segments before @jridgewell/remapping composition (registered in pnpm-workspace.yaml / lockfile). Also pins @babel/plugin-transform-react-jsx@7.28.6 at the repo root.

Approvability

Verdict: Approved

CI/CD setup for EAS mobile preview builds. Changes are primarily workflow configuration, build profiles, and documentation. The app.config.ts change defaults to existing behavior and only affects CI preview builds. The metro-config patch fixes source map handling at build time.

Missing concurrency can race deploys

Medium Severity

The new EAS preview workflow has no concurrency group for the pull request, so several pushes in quick succession can run overlapping deploy/update jobs against the same pr-<number> branch at once, unlike other PR workflows in this repo that cancel in-progress runs per PR.
