+# Codemagic integration plan
+
+Guía para integrar Codemagic en `sf-app-platform`. **Codemagic se usa exclusivamente como herramienta de release a tiendas** (Play Store + App Store), no como CI general. La validación de develop / feature branches sigue siendo local (`melos run analyze`, `melos run test`, `flutter build` manual).
+
+El plan está adaptado a la realidad de este repo (monorepo Melos + pub workspace, configs gitignored, generated files commiteados, fusión legacy↔payment en curso).
+
+## Decisiones tomadas
+
+| Tema | Decisión | Por qué |
+| --- | --- | --- |
+| Alcance | **Solo 4 workflows**: staging + production × Android + iOS | Codemagic = herramienta de release. Development no se corre en CI — la validación es local |
+| Triggers | `fusion-app` → staging, tag → prod | La rama `main` no está activa; `fusion-app` es el integration branch durante la fusión legacy↔payment |
+| Formato de tag prod | `v1.0.0(N)` / `1.0.0(N)` (formato actual) | Mantener convención existente — última release fue `v1.0.0(8)` |
+| Configs JSON | **Codemagic Encrypted Files** (solo staging + production) | Más seguro y auditable que env vars; el repo los tiene gitignored y Codemagic los materializa antes del build |
+| Code generation | **No correr `build_runner` en CI** | 355 `.freezed.dart`/`.g.dart` están commiteados — solo `melos bootstrap` |
+| Quality gates | `melos run analyze --no-select` + `melos run test --no-select` bloqueantes | Si alguien pushea código roto a `fusion-app`, no queremos que llegue a Play Internal Track ni TestFlight. **`--no-select` es obligatorio** (sin TTY melos crashea) |
+| Versionado | `version` desde `pubspec.yaml` (manual), build number desde tag en prod | Como hoy. CI no toca pubspec.yaml |
+| **APP_MODE en builds a tiendas** | **Siempre `legacy`** | Aunque la rama `fusion-app` integra legacy+payment, los AAB/IPA publicados a App Store y Play Store deben arrancar en flujo legacy hasta que el roadmap premium de Treezor esté listo para producción |
+| Web | No incluido | sf-app-platform es mobile-only |
+
+## Cosas del repo que importan (chequeadas, no asumidas)
+
+- **Entry points**: `apps/mobile_app/lib/main_{development,staging,production}.dart`
+- **Configs (gitignored)**: `apps/mobile_app/config/{development,staging,production}.json` — claves: `env`, `apiBaseUrl`, `apiOrigin`, `wsUrl`, `juphoonAppKey`
+- **iOS schemes por flavor**: `development.xcscheme`, `staging.xcscheme`, `production.xcscheme` (ya existen)
+- **iOS Firebase configs por flavor**: `apps/mobile_app/ios/flavors/{dev,stag,prod}/GoogleService-Info.plist` (ya existen — el script Build Phase los copia)
+- **Android Firebase configs**: ya están configuradas. `apps/mobile_app/android/app/google-services.json` (root) contiene los packages `com.savefamily.app.dev` Y `com.savefamily.app.stag` (project `sf-platform-pre`); `src/production/google-services.json` override para `com.savefamily.app` (project `sf-platform-pro`). Commits de referencia: `81284d7e`, `e83adbfd`
+- **Bundle IDs**:
+  - iOS / Android: `com.savefamily.app.dev`, `com.savefamily.app.stag`, `com.savefamily.app`
+- **Bridges nativos**: `flutter_treezor_entrust_sdk_bridge`, `sca_treezor` son `path:` dependencies locales. No requieren maven privado ni Pod source extra
+- **Native repos**: solo `google()` + `mavenCentral()`. Cero credenciales adicionales en Gradle
+- **AntelopAppDelegate caveat**: el swizzling de FCM se rompe si se regenera `Runner.xcodeproj`. CI no debe regenerar el proyecto Xcode
+- **iOS deployment target**: 15.0 mínimo
+- **Dart SDK**: `^3.9.2` → Flutter ≥ 3.27 (requerido por `resolution: workspace` en pubspec raíz)
+- **App Store Connect / Apple Developer**: Team `KQ73NP6L4Q`, Account Holder Jorge Alvarez — la API key para Codemagic la tiene que generar él
+- **App Store IDs**: staging `6759873957`, prod `6759875039`
+- **Play Internal track**: prod Android track id `4700720707717247246`
+
+## Estrategia de configs vía Encrypted Files
+
+En Codemagic UI → **Environment variables → Add encrypted file**. Subir cada JSON con `Path on virtual machine` = path relativo al build dir:
+
+| Archivo local | Path en VM |
+| --- | --- |
+| `apps/mobile_app/config/staging.json` | `apps/mobile_app/config/staging.json` |
+| `apps/mobile_app/config/production.json` | `apps/mobile_app/config/production.json` |
+
+Codemagic los desencripta en disco antes de los scripts. **No hace falta script de materialización**. Si una key rota (ej. `juphoonAppKey`), se re-sube el archivo desde la UI sin tocar el repo ni env vars.
+

+## Scripts
+
+### `project_setup.sh`
+
+```sh
+#!/bin/bash
+set -eu
+
+dart pub global activate melos 7.5.1
+melos bootstrap
+```
+
+Nada de `build_runner`: los `.freezed.dart` y `.g.dart` ya están commiteados (355 archivos). Si en el futuro decidimos dejar de commitearlos, se agrega `melos run generate` acá.
+
+### `analyze_and_test.sh`
+
+```sh
+#!/bin/bash
+set -euo pipefail
+
+melos run analyze --no-select
+melos run test --no-select
+```
+
+Los dos targets ya están definidos en el bloque `melos.scripts` del `pubspec.yaml` raíz.
+
+**Críticos** (aprendidos en Fase 0):
+- `--no-select` es obligatorio en non-TTY. Sin esto, melos prompts interactivamente y crashea con `StdinException`
+- `set -o pipefail` evita que pipes downstream enmascaren un exit code de fallo
+
+### `android_dependencies.sh`
+
+```sh
+#!/bin/bash
+set -eu
+
+cd apps/mobile_app/android
+./gradlew --version
+```
+
+Diferencia con effi: no se regenera el wrapper (`gradle wrapper --gradle-version 7.4`). El repo ya commitea el wrapper actual; regenerarlo en cada build es ruido.
+
+### `android_key_properties.sh`
+
+```sh
+#!/bin/bash
+set -eu
+
+cat > "$CM_BUILD_DIR/apps/mobile_app/android/key.properties" <<EOF
+storePassword=$CM_KEYSTORE_PASSWORD
+keyPassword=$CM_KEY_PASSWORD
+keyAlias=$CM_KEY_ALIAS
+storeFile=$CM_KEYSTORE_PATH
+EOF
+```
+
+El `build.gradle.kts` busca `rootProject.file("key.properties")` → `apps/mobile_app/android/key.properties`.
+
+### `ios_signing_cocoapods.sh`
+
+```sh
+#!/bin/bash
+set -eu
+
+gem install cocoapods -v $COCOAPODS_VERSION
+xcode-project use-profiles --project apps/mobile_app/ios/Runner.xcodeproj
+```
+
+`xcode-project` viene preinstalado en imágenes Mac mini de Codemagic.
+
+### `flutter_build.sh`
+
+Parser adaptado al formato real `1.0.0(N)` y `pubspec.yaml: version: 1.0.0+10`. `APP_MODE` por flavor: staging y production fuerzan `legacy` (lo que se publica a tiendas); development queda en el default del código (`legacy`, pero se puede sobreescribir vía un 3er argumento si en el futuro queremos un smoke test del flujo payment).
+
+```sh

+
+## Environment groups en Codemagic
+
+### `codemagic-common-vars`
+- `FLUTTER_VERSION` = `3.27.0` (mínimo para `resolution: workspace`)
+- `COCOAPODS_VERSION` = `1.15.2`
+- `GOOGLE_BUILDS_CHAT_URL` (opcional, webhook fallos)
+- `GOOGLE_CHAT_URL` (opcional, webhook releases)
+
+### `codemagic-staging`
+- `GCLOUD_SERVICE_ACCOUNT_CREDENTIALS`
+
+### `codemagic-production`
+- `GCLOUD_SERVICE_ACCOUNT_CREDENTIALS`
+- `RELEASE_NOTES_LANGUAGE` = `es-ES` (o lo que defina el equipo)
+- `RELEASE_NOTES` = texto multilinea de release notes
+
+### Code Signing (UI separada de groups)
+- **Android keystore** → uploaded como `upload_keystore`. Codemagic expone `CM_KEYSTORE_PATH`, `CM_KEYSTORE_PASSWORD`, `CM_KEY_PASSWORD`, `CM_KEY_ALIAS`
+- **App Store Connect API integration** → la genera Jorge Alvarez desde App Store Connect → Users and Access → Keys. En CM se llama `SaveFamily ASC Key` (referenciado desde `integrations.app_store_connect`)
+
+### Encrypted Files (UI separada también)
+- `apps/mobile_app/config/staging.json`
+- `apps/mobile_app/config/production.json`
+
+## Bloqueantes antes de prender CI
+
+Cosas que hay que resolver antes de que el primer build dev verde sea posible:
+
+1. **App Store Connect API key** — Jorge Alvarez (Account Holder) tiene que generar la key desde App Store Connect → Users and Access → Integrations → Team Keys, descargar el `.p8` (solo se puede descargar una vez), y configurar la integration en Codemagic
+2. **Provisioning profiles**:
+   - `com.savefamily.app.stag` → tipo **app_store** (para TestFlight)
+   - `com.savefamily.app` → tipo **app_store** (para release)
+   - El perfil `com.savefamily.app.dev` no se usa en CI (solo desarrollo local en Xcode)
+3. **Upload keystore Android** — verificar si ya existe el upload key actual del equipo. Si no, generar uno (`keytool -genkey -v -keystore upload.keystore ...`) y registrarlo en Play Console Internal App Sharing
+4. **Google Play service account** — necesita `androidpublisher` API enabled + permisos en Play Console (Release Manager) para `com.savefamily.app.stag` (staging) y `com.savefamily.app` (production)
+
+## Pasos para arrancar (orden)
+
+1. **Resolver bloqueantes** (sección anterior)
+2. **Crear archivos** en el repo:
+   - `codemagic.yaml`
+   - `codemagic_scripts/*.sh` (8 scripts) con `chmod +x`
+   - Commitear en feature branch + PR a `fusion-app`
+3. **Conectar repo a Codemagic UI** (`SaveFamily/sf-app-platform`)
+4. **Crear los 3 Environment Groups** (common-vars, staging, production) y poblar variables
+5. **Subir Encrypted Files** (2 JSON: staging + production)
+6. **Subir keystore Android** + configurar App Store Connect integration
+7. **Disparar `staging_android` MANUAL** desde la UI (sin esperar push) para validar `melos bootstrap` + analyze + test + build end-to-end. Validar el AAB en Play Internal Track con un tester
+8. **Disparar `staging_ios` MANUAL** — más puntos de falla por signing/Pods/CocoaPods, esperar fricción. Validar el IPA en TestFlight
+9. **Activar trigger automático** en push a `fusion-app` solo cuando ambos staging estén verdes
+10. **Tag de RC para producción** (ej. `0.99.0(1)`) para validar el pipeline de tag-driven release sin afectar producción real
+11. **Primer release real con tag** `1.0.0(N)` solo después de coordinación con stakeholders y validación del RC
+
+## Riesgos y caveats específicos
+
+- **Tiempo de build estimado**: `melos bootstrap` (~1 min) + `melos run analyze` (~2-3 min, 30+ paquetes) + `melos run test` (depende, ~2-5 min) + build (~5-10 min). Total: 10-20 min por workflow. Mac mini m2 escala mejor que linux_x2 para iOS
+- **AntelopAppDelegate**: cualquier `pod install` con `--repo-update` puede regenerar archivos que rompen el swizzling. El `Podfile.lock` ya está commiteado — CI debe usar `pod install` plain, no `pod update`
+- **`resolution: workspace`** requiere Flutter ≥ 3.27. Pinear `FLUTTER_VERSION` exacto en `codemagic-common-vars`, no `latest`
+- **`flutter_secure_storage`** está pinned a `9.2.4` vía `dependency_overrides`. CI no debería romper esto pero si melos hace algo raro con overrides en workspace, validar localmente primero
+- **Tests con backend mock**: hay tests que llaman APIs (`questia_api_test`?). Si fallan en CI sin red, hay que skiparlos con `@Skip()` o un tag de melos. Validar antes del primer push
+- **Flag `--no-select` obligatorio en `melos run`**: en non-TTY (cualquier CI) melos prompts y crashea con `StdinException`. Validado en Fase 0
+- **`set -o pipefail` en todos los scripts**: pipes como `melos run test | tail -50` enmascaran el exit code del comando upstream. Sin pipefail, un fallo de melos se reporta como success. Validado en Fase 0
+- **Release notes en prod**: actualmente se hace manual. Si automatizamos via `android_release.sh` (estilo effi), las release notes vienen de la env var `RELEASE_NOTES`. Cambiar la convención del equipo o seguir manual via Play Console UI
