Use for cloud builds and OTA updates of an Expo + RN app via EAS: configuring eas.json profiles (development/preview/production), managing credentials (APNs key, Android keystore) without committing them to git, submitting builds to App Store Connect / Google Play via EAS Submit, shipping JS-only fixes via EAS Update with channels/branches, EAS Workflows for CI. Triggers on: "set up EAS Build", "OTA update", "EAS Submit", "configure eas.json", "deploy to Play Store / TestFlight". Not for: store metadata/screenshots/IAP (rn-publishing-payments), scaffolding (rn-bootstrap), or the end-to-end deploy orchestration (rn-eas-deploy).

rn-eas-build-submit-update — guardrail for EAS Build / Submit / Update / Workflows
The 5 rules (non-negotiable)
3 profiles in eas.json: development (dev client, internal), preview (TestFlight / Play Internal — test on real devices), production (the store). NEVER ship from a profile not pre-tested in preview.
Credentials server-side via eas credentials. NEVER commit .p12, .p8, *.keystore, *.jks, or google-services.json for production accounts. EAS holds them; local Apple/Google CLI never touches them.
OTA only for JS-only changes. If the diff touches app.json config plugins, native modules, or anything that would change prebuild output → it's a new build, not an Update.
Channels separate environments. preview channel for QA, production channel for end users. Ship updates to preview first, promote to production only after smoke-test.
expo-updates config in app.json is the source of truth for runtime version (runtimeVersion: { policy: "appVersion" } or "sdkVersion"). Mismatched runtime versions = OTAs ignored.
Quick decision tree
"Build, Submit, or Update — which do I need now?" → references/decision-tree.md
"How do I write the eas.json profiles?" → references/eas-json.md
"How do credentials work — where does the cert live?" → references/credentials.md
"How do I set up EAS Workflows for CI?" → references/workflows.md
Common anti-patterns (NEVER do)
❌ Committing certificates / keystores to git.
❌ eas build --profile production without ever having built --profile preview for that commit.
❌ eas update --channel production without --branch <name> and without testing on preview channel first.
❌ Updating app.json config plugins and shipping via OTA — fails silently or crashes on user devices.
❌ Bumping version in app.json without also bumping ios.buildNumber / android.versionCode — store reject.
❌ expo-updates with default runtimeVersion (none) — OTA gets applied to incompatible native builds → crash.
