ci: add parameterized build workflow (env x target x platform)

Manually-triggered, build-only GitHub Actions workflow on GitHub-hosted runners. Inputs: environment (staging/prod), target (all/customer/mitra/ backend/control_center), platform (android/ios/both). Runner split: iOS app jobs run on macos-latest, all else on ubuntu-latest. Apps build debug-signed APKs; control_center bakes VITE_API_BASE_URL; backend exports a docker-save tarball. iOS jobs await per-flavor Xcode schemes + signing.

+# CI Workflows
+
+## `build.yml` — parameterized build
+
+Manually-triggered, **build-only** pipeline (no push, no deploy). Produces downloadable artifacts.
+
+### How to run
+1. GitHub → **Actions** tab → **Build** (left sidebar) → **Run workflow**.
+2. Pick:
+   - **environment** — `staging` or `prod`
+   - **target** — `all`, `customer`, `mitra`, `backend`, or `control_center`
+   - **platform** — `android`, `ios`, or `both` (only affects the customer/mitra apps; ignored for backend/control_center)
+3. **Run workflow**. Open the run; artifacts appear at the bottom of the summary page when it finishes.
+
+(You can also trigger it from the CLI: `gh workflow run build.yml -f environment=staging -f target=all -f platform=android`.)
+
+### Runner split (Linux vs macOS)
+iOS can only be built on macOS, so the workflow routes jobs accordingly:
+
+| Job | Runner |
+|---|---|
+| `customer-ios`, `mitra-ios` | `macos-latest` |
+| `customer-android`, `mitra-android`, `backend`, `control_center` | `ubuntu-latest` |
+
+> ⚠️ **macOS runner minutes bill at ~10× Linux.** That's why `platform` defaults to `android`. Choose `ios`/`both` deliberately.
+
+### What each target produces
+
+| Target | Platform | Tool | Artifact | Notes |
+|---|---|---|---|---|
+| `customer` | android | Flutter | `customer-<env>-android-apk` → `app-<env>-release.apk` | Debug-signed (no keystore in repo). Fine for internal/Firebase App Distribution. |
+| `customer` | ios | Flutter | `customer-<env>-ios-app` (`Runner.app`) | **Unsigned** (`--no-codesign`). See iOS prerequisites below. |
+| `mitra` | android | Flutter | `mitra-<env>-android-apk` | Same as customer-android. |
+| `mitra` | ios | Flutter | `mitra-<env>-ios-app` | Same caveats as customer-ios. |
+| `control_center` | — | Vite | `control-center-<env>-dist` (the `dist/` folder) | `VITE_API_BASE_URL` baked in at build time — see below. |
+| `backend` | — | Docker | `backend-<env>-image` (`*.tar.gz`) | Env-**agnostic** image (config is runtime env vars). Load with `docker load`. |
+
+`all` runs every selected job in parallel; each is independent, so one failing doesn't block the others.
+
+### ⚠️ iOS prerequisites (not satisfied yet)
+The iOS jobs are wired but will **fail until two things are done**:
+1. **Per-flavor Xcode schemes** (`staging`, `prod`) must exist in `ios/Runner.xcodeproj`. Today there's only the default `Runner` scheme, so `flutter build ios --flavor staging` errors with *"The Xcode project does not define custom schemes"*. This mirrors the Android flavor setup but on the iOS side (schemes + build configurations + per-config bundle IDs).
+2. **Code signing** for a distributable `.ipa`: Apple Developer certificate + provisioning profiles stored as GitHub secrets. The current jobs use `--no-codesign`, which only validates that the app **compiles** and produces an unsigned `Runner.app` (not installable on devices).
+
+Until then, `platform=ios`/`both` is useful only once the schemes land. `platform=android` works today.
+
+### Environment specifics
+- **Apps (customer/mitra):** `environment` selects the Flutter flavor + entrypoint + `env/<env>.json` (`--flavor`, `-t lib/main_<env>.dart`, `--dart-define-from-file`). Reminder: `env/staging.json` still has a **placeholder API URL** until the staging backend is deployed.
+- **control_center:** `VITE_API_BASE_URL` is compiled in. Defaults: prod → `https://internal.halobestie.com`, staging → `https://staging-internal.halobestie.com`. Override without editing the workflow by setting repo **Variables** (Settings → Secrets and variables → Actions → Variables): `CC_API_BASE_URL_PROD`, `CC_API_BASE_URL_STAGING`.
+- **backend:** the image is identical across environments; env/secrets are supplied at `docker run` time (see [backend/DEPLOY.md](../../backend/DEPLOY.md)). The `<env>` in the artifact name is just a label.
+
+### Deploying a build artifact (manual, since we don't push yet)
+- **Backend:** download `backend-<env>-image`, copy to the host, then:
+  ```bash
+  gunzip -c halobestie-backend-<env>.tar.gz | docker load
+  # then run per backend/DEPLOY.md
+  ```
+- **control_center:** download `control-center-<env>-dist`, serve the `dist/` behind Nginx (internal-only).
+- **Apps:** download the APK and install / upload to Firebase App Distribution.
+
+### Pinned versions
+Flutter `3.41.9`, JDK `17`, Node `20` (see `env:` block in [build.yml](build.yml)). Bump them there when the team upgrades.
+
+### Not included yet (by design)
+Pushing images to a registry and deploying are intentionally out of scope for this first iteration. When you're ready, the natural next step is a `release.yml` that pushes to GHCR and (optionally, via a self-hosted runner or SSH) deploys to the VPS.

+# Backend — Docker Deployment Guide
+
+Operational guide for building, deploying, and observing the Halo Bestie backend as a **Docker container** on self-hosted infra (VPS, Docker Engine, or Kubernetes). **Not** Cloud Run / serverless.
+
+> Architecture / env-var reference: [../requirement/deployment.md](../requirement/deployment.md) · [.env.example](.env.example)
+
+---
+
+## 1. What gets deployed
+
+A single image (multi-stage [Dockerfile](Dockerfile)) running `node src/server.js`, which starts **two listeners** ([src/server.js](src/server.js)):
+
+| Listener | Bind | Port | Exposed? |
+|---|---|---|---|
+| Public API (`client_app` + `mitra_app`) | `0.0.0.0` | `PUBLIC_PORT` (default **3000**) | **Yes** — publish this |
+| Internal API (control center) | `INTERNAL_HOST` (default `127.0.0.1`) | `INTERNAL_PORT` (default 3001) | **No** — loopback only, never publish |
+
+Runtime image: Node 20 (bookworm-slim), prod-only deps, runs as non-root `node`, native `bcrypt` precompiled in the build stage.
+
+---
+
+## 2. Install Docker (one-time, on the host)
+
+### Ubuntu / Debian VPS
+```bash
+# Remove any old packages, then install Docker Engine from the official repo
+curl -fsSL https://get.docker.com | sh
+
+# Run docker as your user without sudo (log out/in afterward)
+sudo usermod -aG docker "$USER"
+
+# Verify
+docker version
+docker compose version   # Compose v2 ships as a plugin with modern Docker
+```
+
+### Kubernetes
+No Docker Engine needed on nodes — just push the image to a registry your cluster can pull from (see §4) and apply your manifests (§7).
+
+---
+
+## 3. Configure environment
+
+Create `backend/.env.staging` (or `.env.production`) from the template — **never commit it**:
+```bash
+cp .env.example .env.staging
+```
+Fill in at minimum (full list in [.env.example](.env.example)):
+
+| Var | Notes |
+|---|---|
+| `PUBLIC_PORT` | `3000` (keep default unless your proxy expects otherwise) |
+| `INTERNAL_HOST` / `INTERNAL_PORT` | leave default `127.0.0.1:3001` — keeps control center private |
+| `DATABASE_URL` | Postgres connection string |
+| `VALKEY_URL` | `redis://<host>:6379` |
+| `SERVER_TZ` | `UTC` |
+| `AUTH_JWT_SECRET` | **fresh per environment** — never reuse prod's |
+| `FIREBASE_SERVICE_ACCOUNT_PATH` | path to the **mounted** SA JSON, e.g. `/secrets/firebase-sa.json`. Must be from the env's Firebase project (staging = `my-bestie-876ec`) |
+| `XENDIT_ENABLED` | `false` until test keys + webhook are wired |
+| `CC_ORIGIN`, `ADMIN_EMAIL`, `ADMIN_PASSWORD` | control-center access |
+
+> Secrets (`.env`, the Firebase SA JSON) are provided at **runtime** via `--env-file` / volume mounts / k8s Secrets. They are **not** baked into the image (`.dockerignore` excludes `.env*`).
+
+---
+
+## 4. Build & push the image
+
+```bash
+# From the repo root
+docker build -t <registry>/halobestie-backend:staging ./backend
+
+# Push to your registry (Docker Hub, GHCR, GCP Artifact Registry, self-hosted, …)
+docker push <registry>/halobestie-backend:staging
+```
+For a purely single-host setup you can skip the registry and build directly on the host.
+
+---
+
+## 5. Run database migrations (one-off)
+
+Run **before** (re)starting the service. Never auto-migrate on container boot — concurrent replicas would race.
+```bash
+# Migrate (every deploy that includes new migrations)
+docker run --rm --env-file backend/.env.staging \
+  <registry>/halobestie-backend:staging node src/db/migrate.js
+
+# Seed (first deploy only)
+docker run --rm --env-file backend/.env.staging \
+  <registry>/halobestie-backend:staging node src/db/seed.js
+```
+
+---
+
+## 6. Deploy — plain Docker Engine
+
+```bash
+docker run -d --name halobestie-staging \
+  --env-file backend/.env.staging \
+  -p 3000:3000 \
+  -v /opt/halobestie/secrets/firebase-sa.json:/secrets/firebase-sa.json:ro \
+  --restart unless-stopped \
+  --log-driver json-file --log-opt max-size=10m --log-opt max-file=5 \
+  <registry>/halobestie-backend:staging
+```
+- Publish **only** `3000`. Do **not** map `3001`.
+- `--log-opt` enables log rotation — see §8.
+- Put a TLS-terminating reverse proxy (Nginx / Traefik / Caddy) in front for `https://staging-api.halobestie.com`. WebSocket upgrade must be proxied (the apps use `/api/shared/ws`).
+
+### Or with Docker Compose
+A ready-to-use [docker-compose.staging.yml](docker-compose.staging.yml) is included (backend only — Postgres/Valkey are expected via `DATABASE_URL`/`VALKEY_URL`). It publishes only `3000`, mounts the Firebase SA + log volume, and sets json-file rotation. Point it at your image via the `BACKEND_IMAGE` env var (or uncomment `build: .` to build on the host):
+```bash
+cd backend
+cp .env.example .env.staging          # then fill it in
+BACKEND_IMAGE=<registry>/halobestie-backend:staging \
+  docker compose -f docker-compose.staging.yml up -d
+```
+
+---
+
+## 7. Deploy — Kubernetes (sketch)
+
+- **Deployment** with the image, `envFrom` a Secret/ConfigMap, the Firebase SA JSON mounted from a Secret volume at `/secrets/firebase-sa.json`.
+- **Service** exposing only container port `3000`. Liveness/readiness probes: `tcpSocket: { port: 3000 }` (no HTTP health route — TCP probe matches the Dockerfile HEALTHCHECK).
+- Migrations: a one-off **Job** (`command: ["node","src/db/migrate.js"]`) run before rolling out, not an initContainer on every pod.
+- Logs: pods write to stdout (§8) — your cluster's node agent (Fluent Bit / Loki / Cloud Logging) collects them automatically.
+
+---
+
+## 8. Logs — where they go and how to map them
+
+### 8a. Application logs → **stdout/stderr** (the Docker-native way)
+The backend uses Fastify's pino logger (`logger: true` in [src/app.public.js](src/app.public.js) / [src/app.internal.js](src/app.internal.js)), emitting **structured JSON to stdout**, plus a few `console.log` lifecycle lines. It does **not** write its own app-log files. So:
+
+```bash
+# Tail live
+docker logs -f halobestie-staging
+
+# Last 200 lines
+docker logs --tail 200 halobestie-staging
+
+# Pretty-print the JSON (pino output is one JSON object per line)
+docker logs -f halobestie-staging | jq .
+
+# Compose equivalent
+docker compose -f docker-compose.staging.yml logs -f backend
+```
+
+**Rotation (important — default json-file logs grow unbounded):**
+set it per-container as in §6 (`--log-opt max-size=10m --log-opt max-file=5`), or globally in `/etc/docker/daemon.json`:
+```json
+{
+  "log-driver": "json-file",
+  "log-opts": { "max-size": "10m", "max-file": "5" }
+}
+```
+then `sudo systemctl restart docker`.
+
+**Ship logs off-host (optional):** point Docker at a log driver instead of/alongside json-file — e.g. `--log-driver=loki`, `--log-driver=fluentd`, `--log-driver=syslog`, or `--log-driver=gcplogs`. On k8s, stdout is collected by the node logging agent; no per-container config needed.
+
+**Persist raw stdout to a host file (simple VPS option):**
+```bash
+docker run -d --name halobestie-staging ... \
+  <image> > /var/log/halobestie/backend.log 2>&1
+# better: use the json-file driver (above) and read /var/lib/docker/containers/<id>/<id>-json.log,
+# or redirect via your reverse proxy / a sidecar. Prefer a real log driver for rotation.
+```
+
+### 8b. Xendit webhook fallback JSONL → **needs a volume** (only if enabled)
+The one component that writes a **file** is the optional webhook fallback sink ([src/services/webhook-log.service.js](src/services/webhook-log.service.js)), **off by default**. When `XENDIT_WEBHOOK_FALLBACK_ENABLED=true`, it writes rolling JSONL to `XENDIT_WEBHOOK_FALLBACK_DIR` (default `./logs` → `/app/logs` in the container). To keep those across restarts, **mount a volume**:
+```bash
+docker run -d ... \
+  -e XENDIT_WEBHOOK_FALLBACK_ENABLED=true \
+  -e XENDIT_WEBHOOK_FALLBACK_DIR=/app/logs \
+  -v /opt/halobestie/logs:/app/logs \
+  <image>
+```
+(The Compose example in §6 already declares the `backend-logs` volume for this.) If the fallback stays disabled, you don't need this volume — everything is on stdout.
+
+---
+
+## 9. Health, upgrade, rollback
+
+```bash
+# Health — the image has a built-in TCP HEALTHCHECK; check it:
+docker inspect --format '{{.State.Health.Status}}' halobestie-staging
+
+# Upgrade to a new image
+docker pull <registry>/halobestie-backend:staging
+docker run ... node src/db/migrate.js          # if new migrations
+docker stop halobestie-staging && docker rm halobestie-staging
+docker run -d --name halobestie-staging ...    # re-run with the new image
+
+# Rollback = re-run the previous tag/digest. Graceful shutdown is handled:
+# server.js traps SIGTERM and drains the listeners before exit.
+```
+
+---
+

+# Build Flavors — client_app (Android + iOS identity)
+
+Three build flavors map each environment to its own app ID, backend URL, app
+display name, and Firebase config. This lets dev / staging / prod builds sit
+**side-by-side** on one device (distinct package / bundle IDs).
+
+> Scope: **Android flavors + Dart + env files are fully wired.** On iOS, only
+> the **bundle identity** is set (see the iOS section below); the iOS **Xcode
+> build-configuration + scheme wiring** (per-flavor bundle suffixing,
+> per-scheme `GoogleService-Info.plist`) is a separate follow-up that needs a
+> Mac and is NOT done here.
+
+## Flavor table
+
+| Flavor   | applicationId           | App name           | API_BASE_URL                              |
+|----------|-------------------------|--------------------|-------------------------------------------|
+| dev      | `com.mybestie.dev`      | HaloBestie Dev     | `http://192.168.88.247:3000`              |
+| staging  | `com.mybestie.staging`  | HaloBestie Staging | `https://staging-api.halobestie.com` ⚠️\* |
+| prod     | `com.mybestie`          | HaloBestie         | `https://api.halobestie.com`              |
+
+\* staging URL is a **PLACEHOLDER** — confirm the real staging host and update
+`env/staging.json` (see the `_TODO` key there).
+
+The `applicationId` is set in `android/app/build.gradle.kts` via
+`applicationIdSuffix` (dev/staging) on top of the base `com.mybestie`; prod has
+no suffix. The app name comes from a per-flavor `resValue("string","app_name",…)`
+consumed by `android:label="@string/app_name"` in `AndroidManifest.xml`.
+
+## iOS bundle identity — DIFFERENT base from Android ⚠️
+
+The customer app already exists on the App Store under bundle ID
+**`com.asc.hallobestie`** (published by a prior vendor — note the `asc` prefix
+and `hallobestie` spelling). **Decision: v2 ships as an _update_ to that existing
+listing**, so the iOS **prod** bundle ID must stay `com.asc.hallobestie` (you
+cannot change a published app's bundle ID without it becoming a new app). The
+iOS flavors therefore suffix **that** base, NOT the Android `com.mybestie` base:
+
+| Flavor  | Android `applicationId` | iOS bundle ID                  |
+|---------|-------------------------|--------------------------------|
+| dev     | `com.mybestie.dev`      | `com.asc.hallobestie.dev`      |
+| staging | `com.mybestie.staging`  | `com.asc.hallobestie.staging`  |
+| prod    | `com.mybestie`          | `com.asc.hallobestie`          |
+
+A bundle ID differing across platforms is normal. What's done so far on iOS:
+- `ios/Runner.xcodeproj/project.pbxproj` — base `PRODUCT_BUNDLE_IDENTIFIER` set
+  to `com.asc.hallobestie` (+ `com.asc.hallobestie.RunnerTests`). Once iOS
+  schemes are wired, dev/staging suffix off this base.
+- `firebase_options_{dev,staging,prod}.dart` — `iosBundleId` set to the table
+  above. dev's iOS appId/apiKey are now PLACEHOLDERs (the old `com.mybestie`
+  iOS app no longer matches) — register `com.asc.hallobestie.dev` in the dev
+  project and paste the values.
+- `ios/Runner/Info.plist` — `CFBundleURLName` aligned to `com.asc.hallobestie`
+  (the `halobestie://` deeplink scheme itself is unchanged).
+
+Still TODO on iOS (the deferred Mac/Xcode work):
+- The existing `ios/Runner/GoogleService-Info.plist` still lists `com.mybestie`
+  — replace per flavor once the iOS apps are registered.
+- Xcode build configs + schemes to actually apply the `.dev`/`.staging` bundle
+  suffixes per build, with a copy-script selecting the right `GoogleService-Info.plist`.
+- You need access to the **`asc` Apple Developer account** + its signing
+  certs/provisioning profiles to release the prod update.
+
+> **mitra app is unaffected** — it's a brand-new app (`com.mybestie.mitra` +
+> suffixes) on both platforms; only the customer iOS app inherits the legacy
+> `com.asc.hallobestie` identity.
+
+## How the pieces fit
+
+| Concern              | dev                                   | staging                                    | prod                                    |
+|----------------------|---------------------------------------|--------------------------------------------|-----------------------------------------|
+| Dart entrypoint      | `lib/main_dev.dart`                   | `lib/main_staging.dart`                    | `lib/main_prod.dart`                    |
+| Firebase Dart opts   | `lib/firebase/firebase_options_dev.dart` | `…_staging.dart` (PLACEHOLDER)          | `…_prod.dart` (PLACEHOLDER)             |
+| Android Firebase cfg | `android/app/src/dev/google-services.json` | `android/app/src/staging/…` (MISSING) | `android/app/src/prod/…` (MISSING)      |
+| Env / dart-define    | `env/dev.json`                        | `env/staging.json`                         | `env/prod.json`                         |
+
+A bare `flutter run` (no `-t`) still works and defaults to **dev**:
+`lib/main.dart`'s `main()` delegates to `bootstrap(flavor: 'dev', …)`.
+
+## Run / build commands
+
+Each command needs three things: `--flavor <f>`, `-t lib/main_<f>.dart`, and
+`--dart-define-from-file=env/<f>.json`.
+
+### Run on a connected device/emulator
+```bash
+# dev
+flutter run --flavor dev     -t lib/main_dev.dart     --dart-define-from-file=env/dev.json
+
+# staging
+flutter run --flavor staging -t lib/main_staging.dart --dart-define-from-file=env/staging.json
+
+# prod
+flutter run --flavor prod    -t lib/main_prod.dart    --dart-define-from-file=env/prod.json
+```
+
+### Build a release APK
+```bash
+# dev
+flutter build apk --flavor dev     -t lib/main_dev.dart     --dart-define-from-file=env/dev.json
+
+# staging
+flutter build apk --flavor staging -t lib/main_staging.dart --dart-define-from-file=env/staging.json
+
+# prod
+flutter build apk --flavor prod    -t lib/main_prod.dart    --dart-define-from-file=env/prod.json
+```
+
+### Build an App Bundle (Play release)
+```bash
+flutter build appbundle --flavor prod -t lib/main_prod.dart --dart-define-from-file=env/prod.json
+```
+
+Output APKs land in `build/app/outputs/flutter-apk/app-<flavor>-release.apk`.
+
+## ⚠️ CRITICAL warnings
+
+### (a) Every build/install/run command now needs `--flavor`
+Once product flavors exist, a bare `flutter build apk` / `flutter install` /
+`flutter run` **with no `--flavor`** FAILS (Gradle can't pick a flavor). All
+build, install, and run invocations — CI scripts, local muscle memory, IDE
+launch configs — must pass `--flavor <dev|staging|prod>` plus the matching
+`-t lib/main_<flavor>.dart` and `--dart-define-from-file=env/<flavor>.json`.
+
+### (b) The dev applicationId is now `com.mybestie.dev`, not `com.mybestie`
+Anything that references the package name by string must be updated for dev:
+
+- **GA4 DebugView:**
+  ```bash
+  adb shell setprop debug.firebase.analytics.app com.mybestie.dev
+  ```
+- **adb commands** (force-stop, pm clear, am start, grant, etc.):
+  ```bash
+  adb shell am force-stop com.mybestie.dev
+  adb shell pm clear com.mybestie.dev
+  ```
+- **Maestro flows:** any `appId: com.mybestie` must become `appId: com.mybestie.dev`
+  for the dev build. Check `.maestro/` configs and per-flow `appId` headers.
+
+Staging uses `com.mybestie.staging`; prod stays `com.mybestie`.
+
+## Firebase config — STATUS: configured ✅ (2026-06-04)
+
+All apps are registered and config files are in place for **both platforms**,
+across 3 projects (one Firebase project per env):
+
+| Env     | Firebase project       | Android applicationId  | iOS bundle ID                 |
+|---------|------------------------|------------------------|-------------------------------|
+| dev     | `halobestie-clone-dev` | `com.mybestie.dev`     | `com.asc.hallobestie.dev`     |
+| staging | `my-bestie-876ec`      | `com.mybestie.staging` | `com.asc.hallobestie.staging` |
+| prod    | `my-bestie-production` | `com.mybestie`         | `com.asc.hallobestie`         |
+
+In place and verified:
+- `android/app/src/<flavor>/google-services.json` — all 3, each containing a
+  client matching the flavor `applicationId`.
+- `ios/config/<flavor>/GoogleService-Info.plist` — all 3, bundle IDs verified.
+- `lib/firebase/firebase_options_{dev,staging,prod}.dart` — real android + iOS
+  values (regenerated from the native files above; no placeholders left).
+
+### Regenerating after any ID / key change
+Either re-run flutterfire per flavor, or re-download the native files and
+re-extract. Project IDs:
+```bash
+flutterfire configure --project=halobestie-clone-dev  --out=lib/firebase/firebase_options_dev.dart
+flutterfire configure --project=my-bestie-876ec       --out=lib/firebase/firebase_options_staging.dart
+flutterfire configure --project=my-bestie-production  --out=lib/firebase/firebase_options_prod.dart
+```
+
+### Still TODO — iOS only (Mac/Xcode)
+- [ ] iOS **Xcode schemes + build-phase copy script** to apply per-flavor bundle
+      suffixes and select the right `GoogleService-Info.plist` at build time.
+      Until then, iOS bundles only `ios/Runner/GoogleService-Info.plist`.
+- [ ] Replace `ios/Runner/GoogleService-Info.plist` (still the legacy
+      `com.mybestie` dev file) — or let the copy script overwrite it per build.
+- [ ] Prod iOS release needs the **`asc` Apple Developer account** + signing.
+
+## Files in this setup
+
+- `android/app/build.gradle.kts` — `flavorDimensions` + `productFlavors`
+- `android/app/src/main/AndroidManifest.xml` — `android:label="@string/app_name"`
+- `lib/main.dart` — `bootstrap()` + dev-default `main()`
+- `lib/main_dev.dart` / `lib/main_staging.dart` / `lib/main_prod.dart`
+- `lib/firebase/firebase_options_{dev,staging,prod}.dart`
+- `env/{dev,staging,prod}.json`
+- `android/app/src/{dev,staging,prod}/` Firebase config source sets

+PROD google-services.json — NOT YET PRESENT
+===========================================
+
+The Gradle google-services plugin reads this flavor's Firebase config from:
+
+    android/app/src/prod/google-services.json   <-- MISSING
+
+This file is deliberately a README, NOT a fabricated google-services.json.
+A wrong/placeholder google-services.json compiles fine but SILENTLY breaks
+Firebase Analytics and FCM at runtime (no build error, no crash — just no
+events / no push). Do not invent one.
+
+How to produce the real file
+----------------------------
+1. In the Firebase Console for the PRODUCTION project, register an Android app
+   with package name:
+
+       com.mybestie
+
+   (no suffix — prod is the un-suffixed applicationId). Use the SEPARATE prod
+   Firebase console, NOT halobestie-clone-dev. See BUILD_FLAVORS.md.
+
+2. Download the generated google-services.json.
+
+3. Drop it here, replacing this README:
+
+       android/app/src/prod/google-services.json
+
+4. Also generate the Dart options:
+
+       flutterfire configure --project=<prod-project> \
+         --out=lib/firebase/firebase_options_prod.dart
+
+   (firebase_options_prod.dart currently holds PLACEHOLDER values.)
+
+Until both files hold real values, do NOT release a production build.

+# iOS per-flavor Firebase config — client_app
+
+iOS has **no** automatic per-flavor resolution (unlike Android's
+`android/app/src/<flavor>/google-services.json`). Stage the three
+`GoogleService-Info.plist` files here, one per flavor:
+
+```
+ios/config/
+  dev/GoogleService-Info.plist        → bundle com.asc.hallobestie.dev      (dev project)
+  staging/GoogleService-Info.plist    → bundle com.asc.hallobestie.staging  (staging/nonprod)
+  prod/GoogleService-Info.plist       → bundle com.asc.hallobestie          (prod project, live App Store app)
+```
+
+> The customer iOS bundle base is **`com.asc.hallobestie`** (the existing App
+> Store app), NOT the Android `com.mybestie`. See `../../BUILD_FLAVORS.md`.
+
+## Wiring (Xcode — Mac follow-up, not done yet)
+
+The active plist Xcode bundles is `ios/Runner/GoogleService-Info.plist`. To make
+it per-flavor, add a **Run Script** build phase to the Runner target, placed
+**before** "Compile Sources":
+
+```bash
+cp "${PROJECT_DIR}/config/${FLAVOR}/GoogleService-Info.plist" \
+   "${PROJECT_DIR}/Runner/GoogleService-Info.plist"
+```
+
+`${FLAVOR}` is a per-scheme/configuration build setting you define when creating
+the dev/staging/prod schemes (e.g. `FLAVOR = dev` in the dev configuration).
+
+### Single-env shortcut
+If you only need one env working (e.g. dev) before the full scheme setup, just
+drop that env's plist directly at `ios/Runner/GoogleService-Info.plist` — no
+script needed for a single environment.

+# Build Flavors — mitra_app (Android)
+
+The mitra_app has three Android build flavors: **dev**, **staging**, **prod**.
+Each has its own `applicationId`, backend URL, app display name, Dart entrypoint,
+Firebase Dart options, and `google-services.json` source set — so all three can
+be installed side-by-side on one device.
+
+> Scope note: this is **Android + Dart + env-files** only. iOS Xcode schemes are
+> a separate follow-up and are NOT set up yet.
+
+## Flavor matrix
+
+| Flavor  | applicationId               | API_BASE_URL                              | App name                  | Entrypoint            | env file          |
+|---------|-----------------------------|-------------------------------------------|---------------------------|-----------------------|-------------------|
+| dev     | `com.mybestie.mitra.dev`    | `http://192.168.88.247:3000`              | Mitra HaloBestie Dev      | `lib/main_dev.dart`   | `env/dev.json`    |
+| staging | `com.mybestie.mitra.staging`| `https://staging-api.halobestie.com` ⚠️   | Mitra HaloBestie Staging  | `lib/main_staging.dart`| `env/staging.json`|
+| prod    | `com.mybestie.mitra`        | `https://api.halobestie.com`              | Mitra HaloBestie          | `lib/main_prod.dart`  | `env/prod.json`   |
+
+⚠️ The staging `API_BASE_URL` is a **placeholder** — confirm the real staging
+host and update `env/staging.json` + `lib/firebase/firebase_options_staging.dart`.
+
+The `applicationId` suffix is applied in `android/app/build.gradle.kts`
+(`applicationIdSuffix = ".dev"` / `".staging"`; prod has none). The app name is
+emitted per flavor via `resValue("string", "app_name", "...")` and read by
+`android/app/src/main/AndroidManifest.xml` through `android:label="@string/app_name"`.
+
+## Build / run commands
+
+Every command MUST pass `--flavor`, a matching `-t` entrypoint, and
+`--dart-define-from-file` for the env. Examples:
+
+### Run (debug, on a device/emulator)
+```bash
+flutter run --flavor dev     -t lib/main_dev.dart     --dart-define-from-file=env/dev.json
+flutter run --flavor staging -t lib/main_staging.dart --dart-define-from-file=env/staging.json
+flutter run --flavor prod    -t lib/main_prod.dart    --dart-define-from-file=env/prod.json
+```
+
+### Build APK
+```bash
+flutter build apk --flavor dev     -t lib/main_dev.dart     --dart-define-from-file=env/dev.json
+flutter build apk --flavor staging -t lib/main_staging.dart --dart-define-from-file=env/staging.json
+flutter build apk --flavor prod    -t lib/main_prod.dart    --dart-define-from-file=env/prod.json
+```
+
+### Build App Bundle (Play Store)
+```bash
+flutter build appbundle --flavor prod -t lib/main_prod.dart --dart-define-from-file=env/prod.json
+```
+
+A bare `flutter run` (no `-t`) still works — `lib/main.dart` delegates to the
+dev bootstrap — but it builds with no flavor selected on Android, so prefer the
+explicit commands above.
+
+## ⚠️ CRITICAL warnings
+
+1. **`--flavor` is now mandatory for builds.** Once product flavors exist, a
+   bare `flutter build apk` (without `--flavor`) FAILS with a Gradle error
+   (no default flavor). Every build/run command must specify `--flavor` and the
+   matching `-t lib/main_<flavor>.dart` entrypoint.
+
+2. **The dev applicationId changed to `com.mybestie.mitra.dev`.** Any tooling
+   that references the old package id must be updated when running the dev
+   flavor:
+   - `adb` commands: `adb shell pm clear com.mybestie.mitra.dev`,
+     `adb shell am start ... com.mybestie.mitra.dev/...`, etc.
+   - Maestro flows: `appId: com.mybestie.mitra.dev`.
+   - Any deeplink / FCM tooling keyed on the package name.
+   Prod keeps `com.mybestie.mitra`; staging is `com.mybestie.mitra.staging`.
+
+## Firebase config — STATUS: configured ✅ (2026-06-04)
+
+Firebase init is **Dart-side** (`Firebase.initializeApp(options:)` in
+`lib/bootstrap.dart`), driven by the per-flavor
+`lib/firebase/firebase_options_<flavor>.dart`. The mitra app is a **brand-new
+app** on both platforms (no legacy App Store identity), so the iOS bundle base
+is `com.mybestie.mitra` — unlike the customer app, which inherits
+`com.asc.hallobestie`.
+
+All apps registered + config in place across 3 projects (one per env):
+
+| Env     | Firebase project       | Android applicationId         | iOS bundle ID                |
+|---------|------------------------|-------------------------------|------------------------------|
+| dev     | `halobestie-clone-dev` | `com.mybestie.mitra.dev`      | `com.mybestie.mitra.dev`     |
+| staging | `my-bestie-876ec`      | `com.mybestie.mitra.staging`  | `com.mybestie.mitra.staging` |
+| prod    | `my-bestie-production` | `com.mybestie.mitra`          | `com.mybestie.mitra`         |
+
+In place and verified:
+- `android/app/src/<flavor>/google-services.json` — all 3, client matches the flavor applicationId.
+- `ios/config/<flavor>/GoogleService-Info.plist` — all 3, bundle IDs verified.
+- `lib/firebase/firebase_options_{dev,staging,prod}.dart` — real android + iOS values, no placeholders.
+
+### Regenerating after any ID / key change
+```bash
+flutterfire configure --project=halobestie-clone-dev  --out=lib/firebase/firebase_options_dev.dart
+flutterfire configure --project=my-bestie-876ec       --out=lib/firebase/firebase_options_staging.dart
+flutterfire configure --project=my-bestie-production  --out=lib/firebase/firebase_options_prod.dart
+```
+
+### Still TODO — iOS only (Mac/Xcode)
+- [ ] iOS Xcode schemes + build-phase copy script to select the right
+      `GoogleService-Info.plist` per flavor (until then iOS bundles only
+      `ios/Runner/GoogleService-Info.plist`). See `ios/config/README.md`.
+
+> The Google Services Gradle plugin is **not** applied in this app — Android
+> Firebase init is Dart-side. The `src/<flavor>/google-services.json` files are
+> laid out for if/when that plugin is added.
+
+## File map
+
+| File | Purpose |
+|---|---|
+| `android/app/build.gradle.kts` | `flavorDimensions "env"` + `productFlavors` (id suffix + app_name) |
+| `android/app/src/main/AndroidManifest.xml` | `android:label="@string/app_name"` |
+| `android/app/src/dev/google-services.json` | dev Firebase config |
+| `android/app/src/{staging,prod}/google-services.json.README` | placeholders — drop real json here |
+| `lib/bootstrap.dart` | shared `bootstrap()` + `App` widget |
+| `lib/main.dart` | bare entrypoint → delegates to dev |
+| `lib/main_{dev,staging,prod}.dart` | per-flavor entrypoints |
+| `lib/firebase/firebase_options_{dev,staging,prod}.dart` | per-flavor Dart Firebase options |
+| `env/{dev,staging,prod}.json` | dart-define values (`API_BASE_URL`, `FLAVOR`) |

+PROD flavor — google-services.json goes HERE
+============================================
+
+This directory is the `prod` flavor source set. The Google Services Gradle
+plugin reads `android/app/src/prod/google-services.json` when you build the
+prod flavor. It is intentionally MISSING right now.
+
+To make the prod flavor build:
+
+1. In the Firebase Console (the PRODUCTION project), add an Android app with
+   package name:
+
+       com.mybestie.mitra
+
+   (prod has NO applicationIdSuffix — it keeps the base id.)
+
+2. Download the generated `google-services.json`.
+
+3. Drop it in this folder, replacing this README:
+
+       android/app/src/prod/google-services.json
+
+4. Also run `flutterfire configure` for the production project/package and paste
+   the generated Dart values into:
+
+       lib/firebase/firebase_options_prod.dart
+
+DO NOT copy the dev google-services.json here and edit it by hand — the
+mobilesdk_app_id / api_key must come from the real Firebase registration.

+STAGING flavor — google-services.json goes HERE
+================================================
+
+This directory is the `staging` flavor source set. The Google Services Gradle
+plugin reads `android/app/src/staging/google-services.json` when you build the
+staging flavor. It is intentionally MISSING right now.
+
+To make the staging flavor build:
+
+1. In the Firebase Console (the staging / nonprod project), add an Android app
+   with package name:
+
+       com.mybestie.mitra.staging
+
+   (note the `.staging` suffix — set by `applicationIdSuffix` in
+   android/app/build.gradle.kts).
+
+2. Download the generated `google-services.json`.
+
+3. Drop it in this folder, replacing this README:
+
+       android/app/src/staging/google-services.json
+
+4. Also run `flutterfire configure` for that project/package and paste the
+   generated Dart values into:
+
+       lib/firebase/firebase_options_staging.dart
+
+DO NOT copy the dev google-services.json here and edit it by hand — the
+mobilesdk_app_id / api_key must come from the real Firebase registration.

+# iOS per-flavor Firebase config — mitra_app
+
+iOS has **no** automatic per-flavor resolution (unlike Android's
+`android/app/src/<flavor>/google-services.json`). Stage the three
+`GoogleService-Info.plist` files here, one per flavor:
+
+```
+ios/config/
+  dev/GoogleService-Info.plist        → bundle com.mybestie.mitra.dev      (dev project)
+  staging/GoogleService-Info.plist    → bundle com.mybestie.mitra.staging  (staging/nonprod)
+  prod/GoogleService-Info.plist       → bundle com.mybestie.mitra          (prod project)
+```
+
+> The mitra app is a **brand-new app** on both platforms — no legacy App Store
+> identity (unlike the customer app, which inherits `com.asc.hallobestie`).
+
+## Wiring (Xcode — Mac follow-up, not done yet)
+
+The active plist Xcode bundles is `ios/Runner/GoogleService-Info.plist`. To make
+it per-flavor, add a **Run Script** build phase to the Runner target, placed
+**before** "Compile Sources":
+
+```bash
+cp "${PROJECT_DIR}/config/${FLAVOR}/GoogleService-Info.plist" \
+   "${PROJECT_DIR}/Runner/GoogleService-Info.plist"
+```
+
+`${FLAVOR}` is a per-scheme/configuration build setting you define when creating
+the dev/staging/prod schemes (e.g. `FLAVOR = dev` in the dev configuration).
+
+### Single-env shortcut
+If you only need one env working (e.g. dev) before the full scheme setup, just
+drop that env's plist directly at `ios/Runner/GoogleService-Info.plist` — no
+script needed for a single environment.

+
+### Manual staging deploy runbook
+
+Goal: stand up a staging backend so the Android **staging** flavor (`com.mybestie.staging`) has a real `API_BASE_URL` to talk to. Done manually for now (no CI/CD yet — see open ops).
+
+> **Deploy target: self-hosted Docker** (VPS / Kubernetes / Docker Engine) — not Cloud Run. The backend ships a multi-stage [backend/Dockerfile](../backend/Dockerfile) (Node 20, non-root runtime, native `bcrypt` compiled in the build stage). Build with `docker build -t halobestie-backend ./backend`.
+>
+> **Full operational runbook — install Docker, build/push, migrate, run (Docker + Compose + k8s), and log mapping/rotation — lives in [backend/DEPLOY.md](../backend/DEPLOY.md).** The steps below are the staging-bring-up summary.
+
+**A1 — Provision the staging database (Cloud SQL Postgres)**
+1. Create a Cloud SQL Postgres instance (or a separate `halobestie_staging` DB on a shared instance). Pin the **same region** as the Cloud Run service.
+2. Capture its connection string for `DATABASE_URL` (use the Cloud SQL connector / Unix socket form for Cloud Run, or private IP over the VPC connector).
+3. Run migrations + seed against it:
+   ```bash
+   cd backend
+   DATABASE_URL=postgresql://... npm run db:migrate
+   DATABASE_URL=postgresql://... npm run db:seed
+   ```
+
+**A2 — Provision staging Valkey** — self-hosted Docker on the VM is fine for staging (`--appendonly yes`, see [§ Valkey](#valkey)). Note the `VALKEY_URL`.
+
+**A3 — Staging Firebase Admin creds** — the app's staging `google-services.json` / `GoogleService-Info.plist` point at Firebase project **`my-bestie-876ec`**. The backend's `FIREBASE_SERVICE_ACCOUNT` **must be a service-account key from that same project**, or FCM push + token verification will silently target the wrong project. Mount it as a secret and set `FIREBASE_SERVICE_ACCOUNT_PATH` (or switch to a Secret Manager mount).
+
+**A4 — Build the image + run migrations, then start the container.**
+
+Build (on a build host or in CI), then push to your registry:
+```bash
+docker build -t <registry>/halobestie-backend:staging ./backend
+docker push <registry>/halobestie-backend:staging
+```
+
+Run migrations as a **one-off** before (re)starting the service — never auto-migrate on boot (replica race):
+```bash
+docker run --rm --env-file backend/.env.staging \
+  <registry>/halobestie-backend:staging node src/db/migrate.js
+# first deploy only:
+docker run --rm --env-file backend/.env.staging \
+  <registry>/halobestie-backend:staging node src/db/seed.js
+```
+
+Run the service (plain Docker Engine example; k8s = Deployment + Service with the same env/secrets and liveness/readiness probes on `:3000`):
+```bash
+docker run -d --name halobestie-staging \
+  --env-file backend/.env.staging \
+  -p 3000:3000 \
+  -v /path/to/firebase-sa.json:/secrets/firebase-sa.json:ro \
+  --restart unless-stopped \
+  <registry>/halobestie-backend:staging
+```
+- Publish **only** port 3000. The internal listener (3001) stays bound to `127.0.0.1` inside the container — do not map it.
+- `FIREBASE_SERVICE_ACCOUNT_PATH` must point at the mounted path (e.g. `/secrets/firebase-sa.json`), not a baked-in file.
+- Put a TLS-terminating reverse proxy (Nginx / Traefik / Caddy) in front for `https://staging-api.halobestie.com`.
+
+Staging-specific env values (`backend/.env.staging`; see [backend/.env.example](../backend/.env.example) for the full list):
+| Var | Staging value |
+|---|---|
+| `AUTH_JWT_SECRET` | a fresh secret — **not** the prod one |
+| `XENDIT_ENABLED` | `false` until you wire test-mode keys + webhook |
+| `XENDIT_SECRET_KEY` / `XENDIT_WEBHOOK_TOKEN` | Xendit **test** credentials |
+| `XENDIT_SUCCESS/FAILURE_REDIRECT_URL` | staging backend's `/payment/return/*` URLs |
+| `FAZPASS_ENABLED` | `false` (test-user OTP bypass path) unless testing real OTP |
+| `CC_ORIGIN` | staging control-center origin (if deployed) |
+| `ADMIN_EMAIL` / `ADMIN_PASSWORD` | staging control-center login |
+
+> **Public listener only.** The internal listener (port 3001, control center) must stay off the public internet — don't expose it from this Cloud Run service. CC for staging, if needed, goes behind the VPC/VPN per the root architecture rules.
+
+**A5 — Capture the URL.** Point a DNS record (e.g. `staging-api.halobestie.com`) at the host/reverse proxy and terminate TLS there. **This HTTPS URL is the value the app needs** in Phase B.
+
+### App handoff (Phase B) — once A5 gives a URL
+1. Put the real URL in [`client_app/env/staging.json`](../client_app/env/staging.json) + [`mitra_app/env/staging.json`](../mitra_app/env/staging.json) (`API_BASE_URL`), and remove the `_TODO` key from the client file.
+2. Build the staging APK:
+   ```bash
+   cd client_app
+   flutter build apk --flavor staging -t lib/main_staging.dart --dart-define-from-file=env/staging.json
+   ```
+   Output: `build/app/outputs/flutter-apk/app-staging-release.apk`.
+3. Distribute via **Firebase App Distribution** (debug-signed APK is accepted — no upload keystore needed for staging) or share the APK directly. `com.mybestie.staging` installs side-by-side with prod.
+
+> **Release signing is still debug keys** ([client_app/android/app/build.gradle.kts](../client_app/android/app/build.gradle.kts) `release { ... }`). Fine for Firebase App Distribution / direct APK. A real upload keystore is only required if you later publish staging to a Play Store internal-testing track. iOS staging is **not** wired yet (only one `Runner.xcscheme` — no per-flavor schemes/build-configs).
