+## Database Schema Files
+
+**CRITICAL**: The database schema files must be kept in sync with each other. When making schema changes:
+
+| File                           | Purpose                                                     |
+| ------------------------------ | ----------------------------------------------------------- |
+| `sql/master_schema_rollup.sql` | Complete schema used by test database setup and reference   |
+| `sql/initial_schema.sql`       | Base schema without seed data, used as standalone reference |
+| `sql/migrations/*.sql`         | Incremental migrations for production database updates      |
+
+**Maintenance Rules:**
+
+1. **Keep `master_schema_rollup.sql` and `initial_schema.sql` in sync** - These files should contain the same table definitions
+2. **When adding columns via migration**, also add them to both `master_schema_rollup.sql` and `initial_schema.sql`
+3. **Migrations are for production deployments** - They use `ALTER TABLE` to add columns incrementally
+4. **Schema files are for fresh installs** - They define the complete table structure
+5. **Test database uses `master_schema_rollup.sql`** - If schema files are out of sync with migrations, tests will fail
+
+**Example:** When `002_expiry_tracking.sql` adds `purchase_date` to `pantry_items`, that column must also exist in the `CREATE TABLE` statements in both `master_schema_rollup.sql` and `initial_schema.sql`.

+## Secrets and Environment Variables
+
+**CRITICAL**: This project uses **Gitea CI/CD secrets** for all sensitive configuration. There is NO `/etc/flyer-crawler/environment` file or similar local config file on the server.
+
+### Server Directory Structure
+
+| Path                                          | Environment | Notes                                            |
+| --------------------------------------------- | ----------- | ------------------------------------------------ |
+| `/var/www/flyer-crawler.projectium.com/`      | Production  | NO `.env` file - secrets injected via CI/CD only |
+| `/var/www/flyer-crawler-test.projectium.com/` | Test        | Has `.env.test` file for test-specific config    |
+
+### How Secrets Work
+
+1. **Gitea Secrets**: All secrets are stored in Gitea repository settings (Settings → Secrets)
+2. **CI/CD Injection**: Secrets are injected during deployment via `.gitea/workflows/deploy-to-prod.yml` and `deploy-to-test.yml`
+3. **PM2 Environment**: The CI/CD workflow passes secrets to PM2 via environment variables, which are then available to the application
+
+### Key Files for Configuration
+
+| File                                  | Purpose                                              |
+| ------------------------------------- | ---------------------------------------------------- |
+| `src/config/env.ts`                   | Centralized config with Zod schema validation        |
+| `ecosystem.config.cjs`                | PM2 process config - reads from `process.env`        |
+| `.gitea/workflows/deploy-to-prod.yml` | Production deployment with secret injection          |
+| `.gitea/workflows/deploy-to-test.yml` | Test deployment with secret injection                |
+| `.env.example`                        | Template showing all available environment variables |
+| `.env.test`                           | Test environment overrides (only on test server)     |
+
+### Adding New Secrets
+
+To add a new secret (e.g., `SENTRY_DSN`):
+
+1. Add the secret to Gitea repository settings
+2. Update the relevant workflow file (e.g., `deploy-to-prod.yml`) to inject it:
+
+   ```yaml
+   SENTRY_DSN: ${{ secrets.SENTRY_DSN }}
+   ```
+
+3. Update `ecosystem.config.cjs` to read it from `process.env`
+4. Update `src/config/env.ts` schema if validation is needed
+5. Update `.env.example` to document the new variable
+
+### Current Gitea Secrets
+
+**Shared (used by both environments):**
+
+- `DB_HOST`, `DB_USER`, `DB_PASSWORD` - Database credentials
+- `JWT_SECRET` - Authentication
+- `GOOGLE_MAPS_API_KEY` - Google Maps
+- `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET` - Google OAuth
+- `GH_CLIENT_ID`, `GH_CLIENT_SECRET` - GitHub OAuth
+
+**Production-specific:**
+
+- `DB_DATABASE_PROD` - Production database name
+- `REDIS_PASSWORD_PROD` - Redis password (uses database 0)
+- `VITE_GOOGLE_GENAI_API_KEY` - Gemini API key for production
+- `SENTRY_DSN`, `VITE_SENTRY_DSN` - Bugsink error tracking DSNs (production projects)
+
+**Test-specific:**
+
+- `DB_DATABASE_TEST` - Test database name
+- `REDIS_PASSWORD_TEST` - Redis password (uses database 1 for isolation)
+- `VITE_GOOGLE_GENAI_API_KEY_TEST` - Gemini API key for test
+- `SENTRY_DSN_TEST`, `VITE_SENTRY_DSN_TEST` - Bugsink error tracking DSNs (test projects)
+
+### Test Environment
+
+The test environment (`flyer-crawler-test.projectium.com`) uses **both** Gitea CI/CD secrets and a local `.env.test` file:
+
+- **Gitea secrets**: Injected during deployment via `.gitea/workflows/deploy-to-test.yml`
+- **`.env.test` file**: Located at `/var/www/flyer-crawler-test.projectium.com/.env.test` for local overrides
+- **Redis database 1**: Isolates test job queues from production (which uses database 0)
+- **PM2 process names**: Suffixed with `-test` (e.g., `flyer-crawler-api-test`)
+
+### Dev Container Environment
+
+The dev container runs its own **local Bugsink instance** - it does NOT connect to the production Bugsink server:
+
+- **Local Bugsink**: Runs at `http://localhost:8000` inside the container
+- **Pre-configured DSNs**: Set in `compose.dev.yml`, pointing to local instance
+- **Admin credentials**: `admin@localhost` / `admin`
+- **Isolated**: Dev errors stay local, don't pollute production/test dashboards
+- **No Gitea secrets needed**: Everything is self-contained in the container

 ### Configure Environment Variables
 
-Create a systemd environment file at `/etc/flyer-crawler/environment`:
+**Important:** The flyer-crawler application does **not** use local environment files in production. All secrets are managed through **Gitea CI/CD secrets** and injected during deployment.
 
-```bash
-sudo mkdir -p /etc/flyer-crawler
-sudo nano /etc/flyer-crawler/environment
-```
+#### How Secrets Work
 
-Add the following (replace with actual values):
+1. **Secrets are stored in Gitea** at Repository → Settings → Actions → Secrets
+2. **Workflow files** (`.gitea/workflows/deploy-to-prod.yml`) reference secrets using `${{ secrets.SECRET_NAME }}`
+3. **PM2** receives environment variables from the workflow's `env:` block
+4. **ecosystem.config.cjs** passes variables to the application via `process.env`
 
-```bash
-# Database
-DB_HOST=localhost
-DB_USER=flyer_crawler
-DB_PASSWORD=YOUR_SECURE_PASSWORD
-DB_DATABASE_PROD=flyer_crawler
+#### Required Gitea Secrets
 
-# Redis
-REDIS_HOST=localhost
-REDIS_PORT=6379
-REDIS_PASSWORD_PROD=YOUR_REDIS_PASSWORD
+Before deployment, ensure these secrets are configured in Gitea:

-JWT_SECRET=YOUR_LONG_RANDOM_JWT_SECRET
+**Shared Secrets** (used by both production and test):
 
-# Google APIs
-VITE_GOOGLE_GENAI_API_KEY=YOUR_GEMINI_API_KEY

+#### Test Environment Details
+
+The test environment (`flyer-crawler-test.projectium.com`) uses **both** Gitea CI/CD secrets and a local `.env.test` file:
+
+| Path                                                   | Purpose                                  |
+| ------------------------------------------------------ | ---------------------------------------- |
+| `/var/www/flyer-crawler-test.projectium.com/`          | Test application directory               |
+| `/var/www/flyer-crawler-test.projectium.com/.env.test` | Local overrides for test-specific config |
+
+**Key differences from production:**
+
+- Uses Redis database **1** (production uses database **0**) to isolate job queues
+- PM2 processes are named with `-test` suffix (e.g., `flyer-crawler-api-test`)
+- Deployed automatically on every push to `main` branch
+- Has a `.env.test` file for additional local configuration overrides
+
+For detailed information on secrets management, see [CLAUDE.md](../CLAUDE.md).

+
+> **Note:** The dev container runs its own local Bugsink instance at `localhost:8000` - no remote DSNs needed for development.
 
 ### Step 12: Configure Application to Use Bugsink
 
-Update `/etc/flyer-crawler/environment` with the DSNs from step 11:
+The flyer-crawler application receives its configuration via **Gitea CI/CD secrets**, not local environment files. Follow these steps to add the Bugsink DSNs:
 
-```bash
-# Sentry/Bugsink Error Tracking
-SENTRY_DSN=https://YOUR_BACKEND_KEY@bugsink.yourdomain.com/1
-VITE_SENTRY_DSN=https://YOUR_FRONTEND_KEY@bugsink.yourdomain.com/2
-SENTRY_ENVIRONMENT=production
-VITE_SENTRY_ENVIRONMENT=production
-SENTRY_ENABLED=true
-VITE_SENTRY_ENABLED=true
+#### 1. Add Secrets in Gitea
+
+Navigate to your repository in Gitea:
+
+1. Go to **Settings** → **Actions** → **Secrets**
+2. Add the following secrets:
+
+**Production DSNs:**
+
+| Secret Name       | Value                                  | Description             |
+| ----------------- | -------------------------------------- | ----------------------- |
+| `SENTRY_DSN`      | `https://KEY@bugsink.yourdomain.com/1` | Production backend DSN  |
+| `VITE_SENTRY_DSN` | `https://KEY@bugsink.yourdomain.com/2` | Production frontend DSN |
+
+**Test DSNs:**
+
+| Secret Name            | Value                                  | Description       |
+| ---------------------- | -------------------------------------- | ----------------- |
+| `SENTRY_DSN_TEST`      | `https://KEY@bugsink.yourdomain.com/3` | Test backend DSN  |
+| `VITE_SENTRY_DSN_TEST` | `https://KEY@bugsink.yourdomain.com/4` | Test frontend DSN |
+
+> **Note:** The project numbers in the DSN URLs are assigned by Bugsink when you create each project. Use the actual DSN values from Step 11.
+
+#### 2. Update the Deployment Workflows
+
+**Production** (`deploy-to-prod.yml`):
+
+In the `Install Backend Dependencies and Restart Production Server` step, add to the `env:` block:
+
+```yaml
+env:
+  # ... existing secrets ...
+  # Sentry/Bugsink Error Tracking
+  SENTRY_DSN: ${{ secrets.SENTRY_DSN }}
+  SENTRY_ENVIRONMENT: 'production'
+  SENTRY_ENABLED: 'true'
 ```
 
-Restart the application to pick up the new settings:
+In the build step, add frontend variables:
 
-```bash
-pm2 restart all
+```yaml
+VITE_SENTRY_DSN=${{ secrets.VITE_SENTRY_DSN }} \
+VITE_SENTRY_ENVIRONMENT=production \
+VITE_SENTRY_ENABLED=true \
+npm run build
 ```
 
+**Test** (`deploy-to-test.yml`):
+
+In the `Install Backend Dependencies and Restart Test Server` step, add to the `env:` block:
+
+```yaml
+env:
+  # ... existing secrets ...
+  # Sentry/Bugsink Error Tracking (Test)
+  SENTRY_DSN: ${{ secrets.SENTRY_DSN_TEST }}
+  SENTRY_ENVIRONMENT: 'test'
+  SENTRY_ENABLED: 'true'
+```
+
+In the build step, add frontend variables:
+
+```yaml
+VITE_SENTRY_DSN=${{ secrets.VITE_SENTRY_DSN_TEST }} \
+VITE_SENTRY_ENVIRONMENT=test \
+VITE_SENTRY_ENABLED=true \
+npm run build
+```
+
+#### 3. Update ecosystem.config.cjs
+
+Add Sentry variables to the `sharedEnv` object in `ecosystem.config.cjs`:
+
+```javascript
+const sharedEnv = {
+  // ... existing variables ...
+  SENTRY_DSN: process.env.SENTRY_DSN,
+  SENTRY_ENVIRONMENT: process.env.SENTRY_ENVIRONMENT,
+  SENTRY_ENABLED: process.env.SENTRY_ENABLED,
+};
+```
+
+#### 4. Dev Container (No Configuration Needed)
+
+The dev container runs its own **local Bugsink instance** at `http://localhost:8000`. No remote DSNs or Gitea secrets are needed for development:
+
+- DSNs are pre-configured in `compose.dev.yml`
+- Admin UI: `http://localhost:8000` (login: `admin@localhost` / `admin`)
+- Errors stay local and isolated from production/test
+
+#### 5. Deploy to Apply Changes
+
+Trigger deployments via Gitea Actions:
+
+- **Test**: Automatically deploys on push to `main`

-### Install Logstash
+> **Note:** Logstash integration is **optional**. The flyer-crawler application already sends errors directly to Bugsink via the Sentry SDK. Logstash is only needed if you want to aggregate logs from other sources (Redis, NGINX, etc.) into Bugsink.
+
+### Step 1: Create Application Log Directory
+
+Create the log directory and set appropriate permissions:
+
+```bash
+# Create log directory for the flyer-crawler application
+sudo mkdir -p /var/www/flyer-crawler.projectium.com/logs
+
+# Set ownership to the user running the application (typically the deploy user or www-data)
+sudo chown -R $USER:$USER /var/www/flyer-crawler.projectium.com/logs
+
+# Ensure logstash user can read the logs
+sudo chmod 755 /var/www/flyer-crawler.projectium.com/logs
+```
+
+For the test environment:
+
+```bash
+sudo mkdir -p /var/www/flyer-crawler-test.projectium.com/logs
+sudo chown -R $USER:$USER /var/www/flyer-crawler-test.projectium.com/logs
+sudo chmod 755 /var/www/flyer-crawler-test.projectium.com/logs
+```
+
+### Step 2: Configure Application to Write File Logs
+
+The flyer-crawler application uses Pino for logging and currently outputs to stdout (captured by PM2). To enable file-based logging for Logstash, you would need to configure Pino to write to files.
+
+**Current Behavior:** Logs go to stdout → PM2 captures them → `~/.pm2/logs/`
+
+**For Logstash Integration:** You would need to either:
+
+1. Configure Pino to write directly to files (requires code changes)
+2. Use PM2's log files instead (located at `~/.pm2/logs/flyer-crawler-*.log`)
+
+For now, we'll use PM2's log files which already exist:
+
+```bash
+# Check PM2 log location
+ls -la ~/.pm2/logs/
+```
+
+### Step 3: Install Logstash
 
 ```bash
 # Add Elastic APT repository
 wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elastic-keyring.gpg
 echo "deb [signed-by=/usr/share/keyrings/elastic-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list
 
+# Update and install
 sudo apt update
 sudo apt install -y logstash
 ```
 
-### Configure Logstash Pipeline
+Verify installation:
 
-Create `/etc/logstash/conf.d/bugsink.conf`:
+```bash
+/usr/share/logstash/bin/logstash --version
+```
+
+### Step 4: Configure Logstash Pipeline
+
+Create the pipeline configuration file:
+
+```bash
+sudo nano /etc/logstash/conf.d/bugsink.conf
+```
+
+Add the following content (adjust paths as needed):

-Replace `YOUR_BACKEND_DSN_KEY` with the key from your backend project DSN.
+**Important:** Replace `YOUR_BACKEND_DSN_KEY` with the key from your Bugsink backend DSN. The key is the part before the `@` symbol in the DSN URL.
 
-### Start Logstash
+For example, if your DSN is:
+
+```text
+https://abc123def456@bugsink.yourdomain.com/1
+```
+
+Then `YOUR_BACKEND_DSN_KEY` is `abc123def456`.
+
+### Step 5: Create Logstash State Directory
+
+Logstash needs a directory to track which log lines it has already processed:
+
+```bash
+sudo mkdir -p /var/lib/logstash
+sudo chown logstash:logstash /var/lib/logstash
+```
+
+### Step 6: Grant Logstash Access to PM2 Logs
+
+Logstash runs as the `logstash` user and needs permission to read PM2 logs:
+
+```bash
+# Add logstash user to the group that owns PM2 logs
+# If PM2 runs as root:
+sudo usermod -a -G root logstash
+
+# Or, make PM2 logs world-readable (less secure but simpler)
+sudo chmod 644 /root/.pm2/logs/*.log
+
+# For Redis logs
+sudo chmod 644 /var/log/redis/redis-server.log
+```
+
+**Note:** If PM2 runs as a different user, adjust the group accordingly.
+
+### Step 7: Test Logstash Configuration
+
+Test the configuration before starting:
+
+```bash
+sudo /usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/bugsink.conf
+```
+
+You should see `Configuration OK` if there are no errors.
+
+### Step 8: Start Logstash
 
 ```bash
 sudo systemctl enable logstash
 sudo systemctl start logstash
+sudo systemctl status logstash
 ```
 
+View Logstash logs to verify it's working:
+
+```bash
+sudo journalctl -u logstash -f
+```
+

+| No events being processed  | Verify log file paths exist and contain data                                                             |
+| HTTP output errors         | Check Bugsink is running and DSN key is correct                                                          |
+| Logstash not starting      | Run config test: `sudo /usr/share/logstash/bin/logstash --config.test_and_exit -f /etc/logstash/conf.d/` |
+
+### Alternative: Skip Logstash
+
+Since the flyer-crawler application already sends errors directly to Bugsink via the Sentry SDK (configured in Steps 11-12), you may not need Logstash at all. Logstash is primarily useful for:
+
+- Aggregating logs from services that don't have native Sentry support (Redis, NGINX)
+- Centralizing all logs in one place
+- Complex log transformations
+
+If you only need application error tracking, the Sentry SDK integration is sufficient.
