Raw Blame History

Phase 4 — 원격 시즌 배포 + 분석 추상화 구현 계획

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 앱 스토어 업데이트 없이 새 시즌이 등장한다 — 정적 호스팅의 manifest.json을 확인해 새 팩을 SHA256 검증 후 원자적으로 캐시하고, 오프라인이면 캐시→번들 시즌1로 폴백한다. 분석 이벤트는 백엔드 추상화(디버그 로거)로 먼저 깔고 Firebase는 오너 작업 후 연결한다.

Architecture: ContentDownloader(HTTP fetch + SHA256 + temp-write-then-rename)가 캐시 디렉터리를 채우고, ContentRepository가 캐시+번들을 병합해 시즌 목록을 제공한다. 다운로더/캐시 디렉터리/HTTP 클라이언트는 전부 생성자 주입이라 테스트에서 실제 네트워크·path_provider가 필요 없다. 활성 시즌 = 목록의 마지막(seasonId 오름차순 최신). 분석은 AnalyticsBackend 인터페이스 뒤에 숨긴다.

Tech Stack: Flutter 3.35 / Riverpod 2 plain Notifier / 신규 패키지: http, crypto, path_provider (전부 Dart/Flutter 1st-party). Firebase는 이번 플랜에 없음 (오너의 flutterfire configure 후 후속).

Spec: ~/.claude/plans/jolly-waddling-meadow.md의 Phase 4 섹션 + "시즌 콘텐츠 파이프라인" 섹션.

확인된 사실 (구현자 참고):

tool/stage_generator/generate.dart는 spec의 theme를 SeasonTheme.fromJson으로 파싱(확장 비주얼 필드 호환)하고 copyToAssets는 옵셔널(as String?) — 시즌2는 이 키를 빼서 번들에 복사하지 않는다.
SeasonPack.fromJson은 schemaVersion > 1이면 FormatException — 다운로더가 아닌 Repository 로드 단계에서 자연 거부됨.
모든 명령은 /Volumes/Macintosh 2nd/Project/My_Game_Project/BlockSeasons 안에서, 경로 공백 주의.
테스트 개수 보고는 최종 +N: All tests passed! 라인 기준.

Task 1: 의존성 + RemoteManifest 모델

Files:

Modify: pubspec.yaml
Create: lib/data/remote/manifest.dart
Test: test/data/remote/manifest_test.dart
Step 1: 패키지 추가

flutter pub add http crypto path_provider

Expected: pubspec.yaml dependencies에 3개 추가, flutter pub get 성공.

Step 2: 실패하는 테스트 — test/data/remote/manifest_test.dart:

    expect(RemoteManifest.fromJson(manifest.toJson()).toJson(),
        manifest.toJson());
  });

  test('rejects unsupported schema', () {
    expect(
      () => RemoteManifest.fromJson({...json, 'schemaVersion': 99}),
      throwsFormatException,
    );
  });

  test('missing current falls back to last season id', () {
    final m = RemoteManifest.fromJson({...json}..remove('current'));
    expect(m.current, 'season_002');
  });
}

Step 2: 실패 확인

Run: flutter test test/data/content_repository_test.dart Expected: FAIL (cacheDir 파라미터 없음).

Step 3: 구현 — lib/data/content_repository.dart 전체 교체:

Step 4: providers.dart 주입 + main.dart 캐시 준비

lib/state/providers.dart — 기존 contentRepositoryProvider를 교체:

/// Overridden in main() with the real cache directory + downloader; tests
/// override with in-memory fixtures or keep the bundled-only default.
final contentRepositoryProvider =
    Provider<ContentRepository>((ref) => ContentRepository());

(시그니처가 기본 생성자 호환이라 선언 자체는 그대로여도 됨 — 변경 없으면 이 파일은 건드리지 않는다.)

lib/main.dart — runApp 전에 캐시 디렉터리와 다운로더를 준비해 override:

import 'dart:io';

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:path_provider/path_provider.dart';

import 'data/save_repository.dart';
import 'state/providers.dart';

/// Remote content origin. Swap per environment with
/// --dart-define=CONTENT_BASE_URL=...; the default points at the production
/// Firebase Hosting site (configured in Phase 4 owner setup).
const contentBaseUrl = String.fromEnvironment(
  'CONTENT_BASE_URL',
  defaultValue: 'https://block-seasons.web.app/content',
);

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final saveRepository = await SaveRepository.open();

  ContentRepository contentRepository;
  try {
    final support = await getApplicationSupportDirectory();
    final cacheDir = Directory('${support.path}/content');
    contentRepository = ContentRepository(
      cacheDir: cacheDir,
      downloader: ContentDownloader(
        baseUrl: contentBaseUrl,
        cacheDir: cacheDir,
      ),
    );
  } catch (e) {
    debugPrint('content cache unavailable, bundled only: $e');
    contentRepository = ContentRepository();
  }

  runApp(ProviderScope(
    overrides: [
      saveRepositoryProvider.overrideWithValue(saveRepository),
      contentRepositoryProvider.overrideWithValue(contentRepository),
    ],
    child: const BlockSeasonsApp(),
  ));
}

(기존 main의 다른 내용은 유지하면서 위 구조로 합칠 것.)

Task 4: 시즌 갱신 트리거 + 활성 시즌 선택

Files:

Modify: lib/state/providers.dart (seasonRefreshProvider)
Modify: lib/ui/screens/home_screen.dart (refresh listen)
Modify: lib/ui/screens/season_map_screen.dart (list.first → 활성 시즌)
Modify: lib/ui/screens/season_title_screen.dart (list.first → 활성 시즌)
Test: test/state/season_refresh_test.dart
Step 1: 실패하는 테스트 — test/state/season_refresh_test.dart:

import 'dart:io';

import 'package:block_seasons/data/content_repository.dart';
import 'package:block_seasons/state/providers.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:flutter_test/flutter_test.dart';

class _FakeRepo extends ContentRepository {
  _FakeRepo(this.result);
  final bool result;
  int calls = 0;

  @override
  Future<bool> refresh() async {
    calls++;
    return result;
  }
}

void main() {
  test('seasonRefreshProvider runs refresh once and exposes the result',
      () async {
    final repo = _FakeRepo(true);
    final container = ProviderContainer(
      overrides: [contentRepositoryProvider.overrideWithValue(repo)],
    );
    addTearDown(container.dispose);

    expect(await container.read(seasonRefreshProvider.future), isTrue);
    // Re-reading does not re-run (FutureProvider caches).
    expect(await container.read(seasonRefreshProvider.future), isTrue);
    expect(repo.calls, 1);
  });
}

Step 2: 실패 확인

Run: flutter test test/state/season_refresh_test.dart Expected: FAIL (seasonRefreshProvider 없음).

Step 3: 구현

lib/state/providers.dart에 추가:

/// One background content sync per app session. Home listens and refreshes
/// the season list when new packs arrived.
final seasonRefreshProvider = FutureProvider<bool>(
  (ref) => ref.read(contentRepositoryProvider).refresh(),
);

/// The season players land in by default: the newest available.
SeasonPack activeSeason(List<SeasonPack> seasons) => seasons.last;

(activeSeason은 단순 헬퍼 — provider로 만들 필요 없음. providers.dart 하단에 top-level 함수로.)

lib/ui/screens/home_screen.dart — build 시작부에 추가:

ref.listen(seasonRefreshProvider, (_, next) {
  if (next.valueOrNull == true) ref.invalidate(seasonsProvider);
});

lib/ui/screens/season_map_screen.dart — data: (list) => _JourneyMap(pack: list.first) 를 data: (list) => _JourneyMap(pack: activeSeason(list)) 로. (import는 providers.dart에 이미 있음.)

lib/ui/screens/season_title_screen.dart — final pack = list.first; 를 final pack = activeSeason(list); 로. (빈 리스트 가드는 그 위에 이미 있음 — 유지.)

Step 4: 통과 + 커밋

Run: flutter test && flutter analyze Expected: 전체 PASS, 0 issues.

git add lib/state/providers.dart lib/ui/screens test/state/season_refresh_test.dart
git commit -m "feat: session content sync trigger and newest-season selection"

Task 5: AnalyticsService — 백엔드 추상화 + 게임 이벤트 배선

Files:

Create: lib/services/analytics_service.dart
Modify: lib/state/providers.dart (analyticsProvider)
Modify: lib/state/season_flow_notifier.dart (stage_start)
Modify: lib/ui/screens/game_screen.dart (stage_end / endless_end / rescue)
Modify: lib/ui/screens/home_screen.dart (endless_start)
Modify: lib/state/tutorial_notifier.dart (tutorial_done)
Test: test/services/analytics_service_test.dart
Step 1: 실패하는 테스트 — test/services/analytics_service_test.dart:

import 'package:block_seasons/services/analytics_service.dart';
import 'package:flutter_test/flutter_test.dart';

class _RecordingBackend implements AnalyticsBackend {
  final events = <(String, Map<String, Object>)>[];

  @override
  void logEvent(String name, Map<String, Object> params) {
    events.add((name, params));
  }
}

void main() {
  test('typed helpers produce stable event names and params', () {
    final backend = _RecordingBackend();
    final analytics = AnalyticsService(backend);

    analytics.stageStart(seasonId: 'season_001', stageId: 's1');
    analytics.stageEnd(
      seasonId: 'season_001',
      stageId: 's1',
      won: true,
      stars: 3,
      score: 1200,
      movesUsed: 9,
    );
    analytics.endlessStart();
    analytics.endlessEnd(score: 500, isNewBest: true);
    analytics.rescueUsed(type: 'continue');
    analytics.tutorialFinished(skipped: false);

    expect(backend.events.map((e) => e.$1).toList(), [
      'stage_start',
      'stage_end',
      'endless_start',
      'endless_end',
      'rescue_used',
      'tutorial_finished',
    ]);
    expect(backend.events[1].$2, {
      'season_id': 'season_001',
      'stage_id': 's1',
      'won': 1,
      'stars': 3,
      'score': 1200,
      'moves_used': 9,
    });
    expect(backend.events[3].$2, {'score': 500, 'new_best': 1});
  });
}

Step 2: 실패 확인

Run: flutter test test/services/analytics_service_test.dart Expected: FAIL (파일 없음).

Step 3: 구현 — lib/services/analytics_service.dart:

import 'package:flutter/foundation.dart';

/// Where events land. Phase 4 ships the debug logger; the Firebase backend
/// plugs in here after the owner runs flutterfire configure.
abstract class AnalyticsBackend {
  void logEvent(String name, Map<String, Object> params);
}

class DebugAnalyticsBackend implements AnalyticsBackend {
  @override
  void logEvent(String name, Map<String, Object> params) {
    debugPrint('[analytics] $name $params');
  }
}

/// Typed event surface. Booleans are sent as 0/1 ints so every backend
/// (GA4 included) aggregates them the same way.
class AnalyticsService {
  AnalyticsService(this._backend);

  final AnalyticsBackend _backend;

  void stageStart({required String seasonId, required String stageId}) {
    _backend.logEvent('stage_start', {
      'season_id': seasonId,
      'stage_id': stageId,
    });
  }

  void stageEnd({
    required String seasonId,
    required String stageId,
    required bool won,
    required int stars,
    required int score,
    required int movesUsed,
  }) {
    _backend.logEvent('stage_end', {
      'season_id': seasonId,
      'stage_id': stageId,
      'won': won ? 1 : 0,
      'stars': stars,
      'score': score,
      'moves_used': movesUsed,
    });
  }

  void endlessStart() => _backend.logEvent('endless_start', const {});

  void endlessEnd({required int score, required bool isNewBest}) {
    _backend.logEvent('endless_end', {
      'score': score,
      'new_best': isNewBest ? 1 : 0,
    });
  }

  void rescueUsed({required String type}) {
    _backend.logEvent('rescue_used', {'type': type});
  }

  void tutorialFinished({required bool skipped}) {
    _backend.logEvent('tutorial_finished', {'skipped': skipped ? 1 : 0});
  }
}

Step 4: provider + 배선

lib/state/providers.dart:

final analyticsProvider = Provider<AnalyticsService>(
  (ref) => AnalyticsService(DebugAnalyticsBackend()),
);

(+ import '../services/analytics_service.dart';)

lib/state/season_flow_notifier.dart — startSeasonStage 끝에:

ref.read(analyticsProvider).stageStart(
      seasonId: pack.seasonId,
      stageId: pack.stages[index].id,
    );

lib/ui/screens/game_screen.dart — _onSessionChange의 phase 전환 블록:

won 분기 (if (!next.endless) recordWin 가드 안, recordWin 다음):

final flow = ref.read(seasonFlowProvider);
if (flow != null) {
  ref.read(analyticsProvider).stageEnd(
        seasonId: flow.pack.seasonId,
        stageId: flow.stage.id,
        won: true,
        stars: next.starsEarned,
        score: next.score,
        movesUsed: next.moveLimit - next.movesLeft,
      );
}

lost 처리부: endless면 (record(...) 호출 뒤):

ref.read(analyticsProvider).endlessEnd(
      score: next.score,
      isNewBest: isNew,
    );

(record(next.score).then((isNew) {...}) 콜백 안에서 호출.)

lost && !endless (시즌 스테이지 패배):

final flow = ref.read(seasonFlowProvider);
if (flow != null) {
  ref.read(analyticsProvider).stageEnd(
        seasonId: flow.pack.seasonId,
        stageId: flow.stage.id,
        won: false,
        stars: 0,
        score: next.score,
        movesUsed: next.moveLimit - next.movesLeft,
      );
}

주의: 엔드리스의 movesLeft는 1<<30 센티널이고 moveLimit은 0 — 위 stageEnd 호출들은 모두 flow != null(시즌 컨텍스트)에서만 일어나므로 안전.

rescue 두 곳: _resultOverlay의 notifier.useContinue / notifier.addExtraMoves onPressed에 각각:

ref.read(analyticsProvider).rescueUsed(type: 'continue');
// / type: 'extra_moves'

(onPressed를 블록으로 바꿔 분석 호출 후 기존 메서드 호출.)

lib/ui/screens/home_screen.dart — 클래식 onPressed의 startStage 직전:

ref.read(analyticsProvider).endlessStart();

lib/state/tutorial_notifier.dart — _finish()에 skipped 플래그가 필요하므로 시그니처 변경:

Future<void> dismissHud() async {
  if (state != TutorialStep.explainHud) return;
  await _finish(skipped: false);
}

Future<void> skip() async {
  if (state == null) return;
  await _finish(skipped: true);
}

Future<void> _finish({required bool skipped}) async {
  state = null;
  ref.read(analyticsProvider).tutorialFinished(skipped: skipped);
  await ref.read(saveRepositoryProvider).markTutorialDone();
}

Step 5: 통과 + 커밋

Run: flutter test && flutter analyze Expected: 전체 PASS (기존 tutorial_notifier_test 영향 없음 — 외부 동작 동일), 0 issues.

git add lib test/services
git commit -m "feat: analytics abstraction with debug backend and game event wiring"

Task 6: 시즌 2 콘텐츠 생성 + manifest 생성 도구

Files:

Create: content/season_002/spec.json
Create: tool/make_manifest.dart
Generated: content/season_002/pack.json, content/season_002/report.md, content/manifest.json
Step 1: 시즌 2 스펙 작성 — content/season_002/spec.json:

{
  "seasonId": "season_002",
  "version": 1,
  "title": { "en": "Summer Tide", "ko": "여름 파도" },
  "theme": {
    "tileSet": "summer",
    "background": "",
    "backgroundGradient": [4278854704, 4279253322, 4280179302],
    "accentColor": 4285456885,
    "particleType": "petals"
  },
  "stageCount": 30,
  "baseSeed": 20260612,
  "runsPerStage": 80
}

(그라데이션 = 0xFF0A2430/0xFF10394A/0xFF1E5A66 딥 틸, accent = 0xFF6FCDF5 시안 — 비주얼 컴패니언에서 "여름에 어울림"으로 평가된 톤. copyToAssets 없음 = 번들 미포함, 원격 전용. int는 JSON이라 10진수 표기.)

주의: 4285456885 = 0xFF6FCDF5 확인 계산: 0xFF6FCDF5 = 4285713909. 구현 시 반드시 Dart로 검증: print(0xFF6FCDF5); → 그 값을 spec에 쓸 것. (0xFF0A2430 = 4278920240, 0xFF10394A = 4279318858, 0xFF1E5A66 = 4280245862 — 역시 print로 검증 후 기입.)

Step 2: 시즌 2 생성

dart run tool/stage_generator/generate.dart content/season_002/spec.json

Expected: content/season_002/pack.json + report.md 생성, 콘솔에 스테이지별 보정 로그. (60스테이지 시즌1이 ~10초였으므로 30스테이지는 ~5초.)

생성 후 확인:

dart -e "import 'dart:convert'; import 'dart:io'; void main(){ final p=jsonDecode(File('content/season_002/pack.json').readAsStringSync()); print(p['seasonId']); print((p['stages'] as List).length); print(p['theme']); }"

Expected: season_002 / 30 / theme에 backgroundGradient·accentColor 포함.

Step 3: make_manifest.dart 작성 — tool/make_manifest.dart:

import 'dart:convert';
import 'dart:io';

import 'package:crypto/crypto.dart';

/// Builds content/manifest.json from the season packs under content/.
/// Usage: dart run tool/make_manifest.dart
void main() {
  final contentDir = Directory('content');
  final seasons = <Map<String, dynamic>>[];

  final dirs = contentDir
      .listSync()
      .whereType<Directory>()
      .where((d) => File('${d.path}/pack.json').existsSync())
      .toList()
    ..sort((a, b) => a.path.compareTo(b.path));

  for (final dir in dirs) {
    final file = File('${dir.path}/pack.json');
    final bytes = file.readAsBytesSync();
    final pack = jsonDecode(utf8.decode(bytes)) as Map<String, dynamic>;
    seasons.add({
      'seasonId': pack['seasonId'],
      'version': pack['version'],
      'packUrl': 'seasons/${pack['seasonId']}/pack.json',
      'sha256': sha256.convert(bytes).toString(),
    });
  }

  final manifest = {
    'schemaVersion': 1,
    'minAppBuild': 1,
    'current': seasons.isEmpty ? '' : seasons.last['seasonId'],
    'seasons': seasons,
  };

  File('content/manifest.json')
      .writeAsStringSync('${const JsonEncoder.withIndent("  ").convert(manifest)}\n');
  stdout.writeln('manifest.json written with ${seasons.length} season(s).');
}

Step 4: manifest 생성 + 검증

dart run tool/make_manifest.dart
cat content/manifest.json

Expected: season_001과 season_002 항목, current=season_002, 각 sha256 64자 hex.

주의: packUrl 규약은 seasons/<id>/pack.json인데 로컬 content/ 레이아웃은 content/<id>/pack.json — 배포 시 seasons/ 하위로 올리는 구조다. Task 7의 로컬 서빙 단계에서 디렉터리를 그 레이아웃으로 구성한다 (스크립트 제공됨).

Step 5: 커밋

git add content/season_002 content/manifest.json tool/make_manifest.dart
git commit -m "feat: season 2 'Summer Tide' content and manifest generator"

Task 7: 통합 검증 — 로컬 서버로 원격 시즌 E2E + 오너 가이드

Files:

Create: docs/firebase-hosting-guide.md
검증만: 시뮬레이터 E2E
Step 1: 전체 테스트 + analyze

flutter analyze
flutter test

Expected: 0 issues, 전체 PASS. 최종 +N 라인 기록.

Step 2: 로컬 콘텐츠 서버 구성

mkdir -p /tmp/bs_serve/content/seasons/season_001 /tmp/bs_serve/content/seasons/season_002
cp content/manifest.json /tmp/bs_serve/content/
cp content/season_001/pack.json /tmp/bs_serve/content/seasons/season_001/
cp content/season_002/pack.json /tmp/bs_serve/content/seasons/season_002/
cd /tmp/bs_serve && python3 -m http.server 8787 &
cd - 
curl -s http://localhost:8787/content/manifest.json | head -5

Expected: manifest JSON 출력.

Step 3: 시뮬레이터에서 원격 시즌 E2E

xcrun simctl boot "iPhone 17 Pro" 2>/dev/null
flutter build ios --simulator --debug --dart-define=CONTENT_BASE_URL=http://localhost:8787/content
xcrun simctl install booted build/ios/iphonesimulator/Runner.app
xcrun simctl launch booted com.airkjw.blockseasons

수동 확인 (콜드 스타트 2회 — 1회차에 다운로드, listen이 invalidate하면 1회차에도 반영될 수 있음):

홈 → 어드벤처: 시즌 맵이 "Summer Tide / 여름 파도" 30스테이지 + 딥 틸 배경으로 뜨면 성공 (= 스토어 업데이트 없이 시즌2 등장).
시즌 카드도 SEASON 2 표시.
스크린샷: xcrun simctl io booted screenshot /tmp/sim_remote_s2.png → docs/screenshots/sim_remote_season2.png 로 복사.

Step 4: 오프라인 폴백 E2E

kill %1  # python http.server 종료
xcrun simctl uninstall booted com.airkjw.blockseasons   # 캐시 제거(신규 설치 시나리오)
xcrun simctl install booted build/ios/iphonesimulator/Runner.app
xcrun simctl launch booted com.airkjw.blockseasons

확인: 서버가 죽어 있어도 앱이 정상 구동하고 어드벤처 = 번들 시즌1 (First Bloom/첫 개화 60스테이지). 크래시·멈춤 없어야 함. (= 비행기 모드 시나리오)

Step 5: 오너 가이드 작성 — docs/firebase-hosting-guide.md:

# Firebase Hosting 시즌 배포 가이드 (오너용)

## 1회 설정 (약 15분)

1. https://console.firebase.google.com → "프로젝트 추가" → 이름 `block-seasons`
   → Google Analytics **사용 설정** (분석 Phase에서 사용).
2. 터미널에서:
   ```bash
   npm install -g firebase-tools
   firebase login
   cd "/Volumes/Macintosh 2nd/Project/My_Game_Project/BlockSeasons"
   firebase init hosting   # 기존 프로젝트 block-seasons 선택, public 디렉터리: deploy

생성된 호스팅 도메인(예: https://block-seasons.web.app)을 Claude에게 알려주면 앱의 CONTENT_BASE_URL 기본값을 맞춰드립니다.

시즌 배포 (매 시즌 약 1분)

cd "/Volumes/Macintosh 2nd/Project/My_Game_Project/BlockSeasons"
dart run tool/make_manifest.dart
rm -rf deploy/content && mkdir -p deploy/content/seasons
cp content/manifest.json deploy/content/
for d in content/season_*/; do
  id=$(basename "$d")
  mkdir -p "deploy/content/seasons/$id"
  cp "$d/pack.json" "deploy/content/seasons/$id/"
done
firebase deploy --only hosting

배포 직후 모든 유저의 다음 콜드 스타트에서 새 시즌이 나타납니다. 앱 업데이트·심사 불필요.


- [ ] **Step 6: 스크린샷 + 최종 커밋 + 푸시**

```bash
git add docs
git commit -m "feat: phase 4 remote seasons verified end-to-end; owner hosting guide"
git push

Step 7: 오너 보고 — 시즌2가 원격으로 등장한 스크린샷 공유, Firebase 가이드 안내, Phase 5(수익화) 전 오너 선행 작업(AdMob 앱/광고단위 생성) 리마인드.

자체 검토 결과

Spec 커버리지: manifest+SHA256+원자 캐시(T2), 캐시→번들 폴백(T3), 갱신 트리거(T4), 분석 이벤트(T5), 시즌2 콘텐츠+배포물(T6), "스토어 업데이트 없이 시즌2 등장"+"비행기 모드 시즌1 정상" 검증(T7), 오너 Firebase 가이드(T7). 스트릭 UI는 Phase 3에서 완료(범위 제외 명시). theme.zip은 보류 — 현재 테마는 pack.json 내 JSON 필드로 충분(이미지 에셋 도입 시 Phase 6에서 추가).
플레이스홀더: 없음. 단 spec.json의 ARGB 10진수 값은 구현자가 Dart print로 검증 후 기입하도록 명시(계산 실수 방지).
타입 일관성: ContentDownloader(baseUrl:, cacheDir:, client:) (T2 정의 → T3 main 사용), ContentRepository(cacheDir:, downloader:) (T3), seasonRefreshProvider/activeSeason (T4 정의 → T4 사용처), AnalyticsService/AnalyticsBackend (T5), manifest 필드명 (T1 ↔ T2 ↔ T6 make_manifest) 일치 확인.
Firebase 미포함 확인: firebase_core/analytics 의존성 없음 — 오너 작업 완료 후 별도 태스크로 FirebaseAnalyticsBackend 추가 예정.
