📜 Description

Upgrades the performance test apps (TestAppPlain/TestAppSentry) from React Native 0.80.2 to 0.85.1, aligning them with the RN version used in the e2e test matrix.

Changes across both apps:

Component	Before	After
`react-native`	0.80.2	0.85.1
`react`	19.1.0	19.2.3
`@react-native-community/cli*`	19.1.x	20.1.0
`@react-native/{babel-preset,metro-config,typescript-config}`	0.80.2	0.85.1
Android `buildToolsVersion`	35.0.0	36.0.0
Android `compileSdkVersion`/`targetSdkVersion`	35	36
Gradle	8.14.1	9.3.1

Additional changes:

Added edgeToEdgeEnabled=false to gradle.properties (new RN 0.85 template property)
Added nkf gem to Gemfiles (Ruby 3.4 compatibility, per RN 0.85 template)
Set REACT_NATIVE_NODE_MODULES_DIR for perf test iOS builds to fix podspec RN version detection in the yarn workspace (the podspec was resolving packages/core/node_modules/react-native at 0.80.1 instead of the test app's 0.85.1, causing the old Hermes profiling API to be compiled)
Bumped iOS binary size threshold from 1470 to 1550 KiB to accommodate the increased Sentry-vs-plain diff after the RN upgrade
Relaxed iOS startup time diffMin from -20 to -3000 — on RN 0.85.1, the plain app consistently shows ~2.6s slower startup via Appium's activateApp() duration measurement. This is a measurement artifact (not real overhead); the diffMax still guards against SDK overhead regressions. See Flaky E2E Metrics App Start Time #3413

Notes:

newArchEnabled is intentionally kept as false (default). CI toggles it for the new-arch matrix variant.

💡 Motivation and Context

Closes #4426

This is a followup on #4414 which bumped the apps from RN 0.70.6 to 0.70.15 as a minimal fix. Upgrading to 0.85.1 brings the perf test apps in line with the e2e test matrix and modern Android/iOS tooling.

💚 How did you test it?

CI — monitoring the metrics job for binary size and startup time regressions.

📝 Checklist

I added tests to verify changes
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
I updated the docs if needed.
I updated the wizard if needed.
All tests passing
No breaking changes

🔮 Next steps

Investigate improving the iOS startup time measurement to use a more reliable signal than Appium activateApp() duration (related: Flaky E2E Metrics App Start Time #3413)

The podspec's node resolution finds packages/core/node_modules/react-native (0.80.1) instead of the perf test app's (0.85.1) due to yarn workspace symlink resolution. This causes NEW_HERMES_RUNTIME to not be defined, and the old Hermes static profiling API (removed in RN 0.85) to be compiled. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The RN 0.80 to 0.85 upgrade increased the Sentry-vs-plain iOS binary size diff from ~1.44 MiB to ~1.51 MiB. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

LGTM!

On RN 0.85.1, the iOS startup time test consistently shows the plain app ~2.6s slower than the Sentry app. This is a measurement artifact of using Appium's activateApp() duration rather than actual UI render time — the command returns at different times based on binary characteristics unrelated to SDK overhead. Relaxing diffMin to -3000 for iOS only. Android keeps -20 as it doesn't exhibit this behavior. The diffMax (150ms) still catches real SDK overhead regressions.
