🚫 Major version bump — flagged for review (not auto-merged).

• Package: @babel/core (devDependency, declared in apps/desktop/package.json; hoisted, so it also drives apps/mobile), 7.29.7 → 8.0.1 — a major (v7 → v8) release.

CI status: ❌ Desktop Checks (35/35 suites) and ❌ Mobile Checks (17/17 suites) fail. All other checks pass. The failure is a direct consequence of this bump, not a flake:

Starting from Babel 8.0.0, the 'loadPartialConfig' function expects a callback.
If you need to call it synchronously, please use 'loadPartialConfigSync'.
  at loadPartialConfig (node_modules/@babel/core/lib/index-shared.js)
  at ScriptTransformer._getCacheKey (node_modules/@jest/transform/build/ScriptTransformer.js)

Breaking changes relevant to this codebase

• loadPartialConfig is now async in Babel 8 — Jest 29's @jest/transform (babel-jest) still calls it synchronously. This breaks every test suite on both platforms before a single test runs. There is no code we own to fix; the incompatibility is between the pinned Jest 29 toolchain and Babel 8. Affected: apps/desktop/** and apps/mobile/** Jest runs (both use jest ^29.7.0 / babel-jest ^29.7.0).

Breaking changes NOT relevant (APIs/features we don't use)

• preset-env useBuiltIns removal (#18079) — we don't use @babel/preset-env.
• @babel/runtime-corejs3 corejs export removal (#18036) — not used.
• Parser locations: "packed" removal (#18034) — not used.
• modules: auto ESM-support fallback (#18069) — our configs don't rely on it.
• No source file imports @babel/core APIs directly; it is used only transitively via babel.config.js presets and Jest transform.

Peer dependency impacts (cascading updates required — this is not a drop-in)

• jest / babel-jest ^29.7.0 → would need Jest 30+ (first line with Babel-8-compatible transform).
• jest-expo ^55.0.13, babel-preset-expo (Expo SDK ~55.0.11), and @react-native/babel-preset 0.86.0 (RN 0.86.0) all ship Babel 7 presets. Babel 8 support has to land in the Expo/React-Native toolchain first.
• Effectively this is an ecosystem-wide migration (Jest + Expo + RN Babel presets), not a single dependency bump.

Recommendation: Do not merge. Hold (or close) until the Expo SDK / React-Native / Jest toolchain officially supports Babel 8. Auto-fixing was intentionally not attempted: the break is in third-party transform code, and forcing Jest 30 / a Babel-8 preset ahead of Expo+RN support risks a much larger, riskier change than a dev-dependency bump warrants. Dependabot will re-open a compatible bump once the toolchain catches up.
