+## Blocker
+
+`flutter build ipa --release --build-name=1.0.2 --build-number=54 --export-method app-store ...` failed during IPA export:
+
+```text
+error: exportArchive No Accounts
+error: exportArchive No signing certificate "iOS Distribution" found
+```
+
+Local keychain currently has only:
+
+```text
+Apple Development: Ejun Park (9NWQBWJ4DF)
+```
+
+The repository also has no iOS/TestFlight GitHub Actions workflow, no Fastlane setup, and the visible GitHub environment secrets for `staging` only cover Android/Google Play release credentials.
+
+## Next steps
+
+1. Add an Apple Distribution certificate and App Store provisioning profile for `club.devkor.ontime.ios`, or configure Xcode/App Store Connect account access for automatic signing.
+2. Re-run the IPA build:
+
+```sh
+flutter build ipa --release \
+  --build-name=1.0.2 \
+  --build-number=54 \
+  --export-method app-store \
+  --dart-define=ENV=staging \
+  --dart-define=REST_API_URL=https://ontime-back.duckdns.org \
+  --dart-define=GOOGLE_RESERVED_CLIENT_ID_IOS=com.googleusercontent.apps.456571312261-e0g33a9qnct35j1uud89dmfcnv9lffeq
+```
+
+3. Upload the generated IPA to App Store Connect/TestFlight with Xcode Organizer or a configured App Store Connect API key workflow.
